Welcome to our audio round up of everything on the blog during August. 

As the world continues to be in the grips of the Coronavirus pandemic there have been more papers looking at all aspects of this disease.

Simon reviewed the latest paper on Hydroxychloroquine and Charlie collated some of the top papers covering aspects from aerosol spread and use of CPAP to the effect on vulnerable groups and the effect on staff psychological health

It's not all COVID though. Sepsis is a condition we all want to be able to treat more effectively. Sadly there doesn't seem to be any encouraging news about the use of Vitamin C, Steroids and Thiamine in this latest RCT.

Many of the St Emlyn's group have special expertise in toxicology and Gareth wrote this incredibly informative post about the use of GBL. If you're not sure what "ChemSex" is then this post from a few years ago by Janos is worth a read.

The anonymously written "Look at what they make you give" post really struck a chord with readers, with an astonishing number of views. There are messages here for us all.

The numbers of Lesson Plans available continue to grow. We've had some great feedback following their use in induction. If tyou've not seen them yet, do have a look and let us know what you think.

A Comprehensive Review of St Emlyn’s Blog: August 2019 Highlights

Welcome to St Emlyn’s blog and podcast, where we reflect on the key topics and research from August 2019. In this review, we’ll explore the most impactful discussions and studies, providing valuable insights for emergency medicine professionals. From managing lower GI bleeding and addressing climate change in anaesthesia to examining PTSD in emergency services and the future of diagnostics, this post summarizes essential takeaways that are shaping our field.

Managing Lower GI Bleeding in the Emergency Department

One of the significant topics covered was the management of acute lower gastrointestinal (GI) bleeding, a common but challenging condition in the emergency department (ED). The complexity of managing these cases often lies in determining the correct priority of care, appropriate management strategies, and even the correct speciality for handling these patients.

We reviewed a consensus guideline from the British Society of Gastroenterology and Hepatology, published in Gut, which offers practical recommendations for the diagnosis and management of acute lower GI bleeds. The guideline emphasizes the importance of using stratification tools to distinguish between stable and unstable patients, which can help streamline management in the ED.

For stable patients, the Oakland score is recommended. This scoring system helps identify which patients can be safely managed on an outpatient basis, reducing unnecessary hospital admissions. Conversely, patients with a major bleed should be admitted and scheduled for a colonoscopy at the earliest opportunity. The guideline also highlights the value of CT angiography for hemodynamically unstable patients, a practice increasingly integrated into emergency care.

Transfusion thresholds, set at 70 grams per litre, align with standard practices in other clinical settings, with adjustments for patients with cardiovascular disease. The guideline also recommends having dedicated GI bleed leads within trusts to ensure seamless coordination with emergency services.

Sustainability and Climate Change in Anesthesia

Another crucial discussion from August focused on the environmental impact of healthcare, particularly in anaesthesia. In the UK, healthcare is a significant contributor to climate change, driven by factors like travel, disposable materials, and the use of anaesthetic gases such as nitrous oxide and desflurane.

A key paper by Cliff Shelton and colleagues underscores the need to adopt more sustainable practices in anaesthesia. For example, desflurane is approximately 3,000 times more potent as a greenhouse gas than carbon dioxide. The paper advocates for reducing the use of high-polluting gases and considering greener alternatives where possible.

This shift towards sustainability in healthcare is essential, although challenging, given the nature of medical practice. However, small changes, such as reducing nitrous oxide use in departments where alternatives exist, can collectively make a significant difference. The paper serves as a call to action for healthcare professionals to be more mindful of their environmental impact and to seek sustainable solutions in their practices.

Pre-Hospital Care: Comparing Macintosh and McGrath Laryngoscopes

The debate over the best laryngoscope for pre-hospital rapid sequence intubation (RSI) is ongoing, and in August, we reviewed a study that contributed valuable data to this discussion. Published in Critical Care Medicine, the study compared the Macintosh and McGrath laryngoscopes in pre-hospital settings, involving 514 adult emergency patients.

The study found that both devices were equally effective for pre-hospital RSI. Notably, it also revealed that switching to a different device after a failed intubation attempt was more successful than repeating the attempt with the same device. This finding aligns with the 30-second RSI drills many practitioners use, which advocate for changing the approach after a failed attempt.

These findings have practical implications for both pre-hospital and in-hospital care. In the ED, switching to a video laryngoscope, such as the McGrath, after a failed intubation attempt could improve patient outcomes. As video laryngoscopes become more accessible in emergency departments, integrating them into RSI protocols could be a beneficial strategy.

PTSD in Emergency Services: Rusty Carroll’s Series

Rusty Carroll’s ongoing series on PTSD within the ambulance service continues to be one of the most impactful contributions to the St Emlyn’s blog. The August instalment focused on the aftermath of PTSD, exploring the journey towards understanding what “normal” looks like after such an experience.

Rusty’s candid reflections resonate with many in the emergency services community, highlighting the mental health challenges prevalent in our field. The series has received positive feedback, with many readers finding comfort and validation in Rusty’s experiences.

However, the widespread relatability of this series also underscores a concerning reality: many emergency service professionals are struggling with similar issues. As a community, we need to support one another, promote mental health awareness, and advocate for resources to address the psychological toll of our work. Revisiting Rusty’s previous installments in this series is highly recommended for a deeper understanding of the complex emotions associated with PTSD in emergency services.

The Realities of Packed Red Cell Transfusions

Another fascinating topic from August was the metabolic and biochemical characteristics of packed red cell transfusions, which have significant implications for trauma care in the ED. This discussion was sparked by a conversation on Twitter, leading to critical reflections on the assumptions we hold about blood transfusions.

In trauma care, blood is often regarded as a superior alternative to crystalloids. However, the reality of what we’re transfusing—packed red cells—is quite different from whole blood. A study we reviewed highlighted some surprising statistics about the contents of packed red cells, including a pH of 6.79, a potassium level of 20, and a lactate level of 9.4. These figures reveal that packed red cells are far from the idealized image of whole blood.

The metabolic implications of these characteristics are significant, particularly in the context of massive transfusions. For instance, packed red cells have low levels of 2,3-DPG, which affects their ability to release oxygen to tissues. This raises important questions about how we use blood in trauma resuscitation and whether our current practices are truly optimal.

There’s also an ongoing pre-hospital trial in the UK, known as the RePHILL trial, which is examining the outcomes of patients randomized to receive either blood or no blood in pre-hospital settings. The results of this trial are eagerly anticipated and could challenge the assumption that blood is always better. This could lead to more nuanced transfusion practices in the future.

The Future of Diagnostics: Insights from Rick Body

Finally, we explored the future of diagnostics with insights from Rick Body. His presentation, originally given at the St Emlyn’s Live conference, offers a compelling vision of where diagnostics in the ED is heading. With the rise of machine learning, artificial intelligence (AI), and personalized diagnostics, the landscape of emergency medicine is rapidly evolving.

These technologies are already being integrated into diagnostic processes, but they bring new challenges. The data generated by AI and machine learning can be complex, requiring a shift in how we interpret diagnostic results. We must move away from binary thinking and embrace a more nuanced understanding that includes probabilities, uncertainties, and complexities.

As emergency medicine professionals, we need to prepare for this shift by engaging with these new technologies and incorporating them into our clinical practice. The future of diagnostics is exciting, but it will require ongoing education and adaptation to fully harness its potential.

Conclusion

August 2019 was a month rich with insightful discussions and important research that continue to influence our practice in emergency medicine. From managing lower GI bleeding and the environmental impact of anaesthesia to the complexities of blood transfusions and the future of diagnostics, these topics highlight the diverse challenges and opportunities we face in the ED.

The Paradox of a Good Day in Emergency Medicine: Key Insights

Emergency medicine is a field full of paradoxes, where the definition of a "good day" can differ starkly between healthcare professionals and their patients. This contradiction was a central theme in the discussions from June, which included reflections on the Don’t Forget the Bubbles (DFTB) conference, as well as key topics like the emotional toll of emergency medicine, the evolving nature of adolescent healthcare, and the importance of continuous learning.

Don’t Forget the Bubbles Conference: A Valuable Resource for Pediatric Emergency Medicine

The DFTB conference, held in London this year, has quickly become an essential event for those involved in pediatric emergency medicine. With a focus on both pediatric and adolescent healthcare, the conference offers invaluable insights and practical advice that can benefit even those who primarily work in adult emergency medicine.

One of the standout topics from the conference was the Paradox of a Good Day in Emergency Medicine. This paradox arises from the nature of emergency medicine, where a "good day" for a clinician—filled with successful procedures and exciting cases—often coincides with what is likely the worst day of a patient’s life. This duality highlights the emotional and ethical complexities that emergency physicians must navigate. As practitioners advance in their careers, they often shift from focusing on the technical aspects of their work to becoming more aware of the profound impact these situations have on patients and their families.

The Emotional and Psychological Impact of Emergency Medicine

The emotional burden of emergency medicine was another significant theme at the DFTB conference, especially in sessions led by Kim Holt and Neil Spenceley. Holt, who has been involved in whistleblowing in the high-profile Baby P case, shared her experiences of dealing with criticism and professional challenges. Her story serves as a reminder of the resilience required to navigate the ethical and emotional complexities of healthcare.

Spenceley’s session on doctors in distress emphasized the importance of creating supportive systems within healthcare departments. He argued that instead of focusing on making individuals more resilient, we should design systems that inherently support healthcare professionals. This shift in perspective is crucial in addressing the high levels of burnout and stress among emergency medicine practitioners.

Laura Howard’s research on the psychological well-being of emergency physicians further explored this issue. Her qualitative study, which involved interviews with senior emergency physicians, revealed that the emotional impact of the job affects everyone, regardless of their experience level. Events like traumatic deaths, particularly those involving children or body disruptions, were identified as particularly distressing and had lasting effects on the practitioners involved. Howard’s work underscores the need for robust support systems to help clinicians manage the cumulative toll of their work.

Bridging the Gap in Adolescent Medicine

The DFTB conference also shed light on the often-overlooked area of adolescent healthcare. As healthcare providers, we tend to categorize patients as either adults or children, but adolescents require a tailored approach that addresses their unique needs. Russell Viner, a leader in pediatric healthcare, discussed how the concept of adolescence has evolved over time. In previous generations, adolescence was a brief period between puberty and adulthood, often marked by early milestones like starting a family. Today, however, adolescence is prolonged, with young people delaying traditional markers of adulthood due to social, educational, and economic factors.

This shift has significant implications for how we approach healthcare for adolescents. In our practice, we must ensure that we are not only addressing the physical health of teenagers but also their mental and emotional well-being. This includes creating healthcare environments that are welcoming and appropriate for adolescents and offering resources that cater to their specific health concerns.

Continuous Learning: Beyond ATLS and Traumatic Cardiac Arrest

The importance of continuous learning and staying current with the latest research and best practices was another key message from June. Alan Grayson’s talk on going beyond ATLS (Advanced Trauma Life Support) was particularly impactful. While ATLS has been a cornerstone of trauma care globally, Grayson challenged us to think critically about its limitations, especially in high-income countries where multi-disciplinary teams are the norm.

Grayson emphasized the need to focus on the basics—such as administering tranexamic acid, providing adequate analgesia, and ensuring timely administration of antibiotics—before diving into more advanced interventions like REBOA (Resuscitative Endovascular Balloon Occlusion of the Aorta). This back-to-basics approach serves as a crucial reminder that even in a high-tech medical environment, the fundamentals of care are what ultimately save lives.

Jason Smith’s session on traumatic cardiac arrest offered new insights into how we approach this challenging situation. Traditional management has focused on chest compressions, adrenaline, and fluid resuscitation, but emerging evidence suggests that in cases of traumatic cardiac arrest, these interventions may not be as beneficial as once thought. Instead, giving blood and stopping the bleeding were identified as more critical interventions. However, Smith cautioned that this approach should be reserved for hypovolemic cardiac arrest, highlighting the importance of understanding the underlying cause of the arrest before determining the treatment course.

The Reality of Intraosseous (IO) Blood Sampling

A more technical but equally important topic discussed in June was the use of intraosseous (IO) blood sampling. For years, many clinicians have been taught that IO access can provide reliable blood samples for analysis. However, recent evidence suggests otherwise. A systematic review revealed that while it might be possible to obtain certain values like hemoglobin and sodium, the reliability of these results is questionable. Moreover, using IO samples for blood gas analysis or putting marrow through automatic analyzers can lead to equipment malfunction, a concern that has understandably caused anxiety among laboratory staff.

Given this evidence, it’s clear that we need to rethink our approach to IO blood sampling. While it might still have a place in certain situations, particularly for microbiological cultures, relying on IO samples for comprehensive blood analysis is not advisable. This is another example of how continuous learning and critical evaluation of existing practices are essential for improving patient care and ensuring the best possible outcomes.

Conclusion: Moving Forward with Insights from June

As we reflect on the lessons from June, it’s evident that emergency medicine is a constantly evolving field that demands both continuous learning and emotional resilience. Whether through attending conferences like Don’t Forget the Bubbles, staying updated on the latest research, or addressing the psychological impact of our work, it’s clear that adaptation and mutual support are key to thriving in this challenging yet rewarding profession.

At St Emlyn's, we are committed to fostering a culture of lifelong learning, open discussion, and mutual support. As we move into the second half of the year, let’s carry forward the insights we’ve gained, keep pushing the boundaries of our knowledge, and continue to support each other in the demanding yet rewarding field of emergency medicine. Take care, and keep up the incredible work you do.

St. Emlyn's Podcast: Key Insights from May in Emergency Medicine

As we transition into the warmer months, it's an opportune time to reflect on recent discussions and developments within the field of emergency medicine, particularly those highlighted in the latest episode of the St. Emlyn's podcast. This episode covered a wide range of topics, from workplace safety to advancements in pediatric care and innovative approaches in patient management. Below is a comprehensive summary of the key points discussed.

Workplace Safety: A Pressing Concern

The podcast began with a reflection on a recent violent incident at Newham Emergency Department (ED), which served as a stark reminder of the dangers healthcare professionals face daily. Emergency departments, by their very nature, are open and accessible, making them vulnerable to violent incidents. This recent attack has prompted a nationwide reassessment of safety measures, with many EDs enhancing their protocols to protect staff.

The conversation emphasized that violence in the workplace should never be normalized. It’s crucial that healthcare professionals feel safe and supported in their working environment. Leadership within departments plays a critical role in this, not only by implementing robust safety protocols but also by fostering a culture of solidarity and mutual support among staff. The incident at Newham underscores the need for constant vigilance and proactive measures to ensure the safety of everyone working in emergency medicine.

Leadership in Education: Simon Carley’s New Role

In more positive news, Simon Carley’s recent appointment as the CPD (Continuing Professional Development) lead for the college was discussed. This role is a significant milestone, not just for Simon but also for the integration of modern educational approaches within formal medical education. Simon’s involvement with St. Emlyn's has long been focused on innovative, social media-driven education, and this new role offers an opportunity to bring these methods into a broader educational framework.

The appointment highlights the value of combining traditional education with the dynamic, accessible formats offered by the #FOAMed (Free Open Access Meducation) community. It’s a recognition that medical education can benefit from new perspectives and that the integration of these ideas can enhance the learning experiences for healthcare professionals.

Pediatric Status Epilepticus: Evaluating Second-Line Agents

The discussion moved to a detailed analysis of pediatric status epilepticus, focusing on the findings from two key trials: the Eclipse trial and the ConSEPT trial. These studies compared the efficacy of levetiracetam (Keppra) and phenytoin as second-line agents for stopping seizures in children.

The trials found no significant difference between the two drugs in terms of their effectiveness, which has led to debate within the medical community about whether to switch from phenytoin to levetiracetam. While levetiracetam is perceived as easier to administer and safer, the lack of a clear superiority has left the decision somewhat open. However, the ease of use and safety profile of levetiracetam make it an appealing option, and some institutions are considering making the switch.

For clinicians, the takeaway is that while both drugs are viable options, the choice may ultimately come down to individual preferences and institutional protocols. The trials underscore the importance of continuous evaluation of treatment options, particularly in complex cases like pediatric seizures.

Understanding Clinical Trials: The Importance of Statistical Literacy

Simon Carley also highlighted the importance of understanding the statistical nuances in clinical trials, particularly the difference between demonstrating a difference between treatments and establishing their equivalence. This distinction is crucial for accurately interpreting research findings and making informed clinical decisions.

The discussion emphasized that clinicians must be cautious in how they interpret trial results, particularly when it comes to determining whether treatments are genuinely equivalent or if the lack of a significant difference merely reflects the study’s design. This level of critical appraisal is essential for ensuring that new research is applied correctly in clinical practice.

Prolonged Field Care in the ED: Learning from Military Medicine

Another topic discussed was prolonged field care, a concept borrowed from military medicine that is becoming increasingly relevant in emergency departments due to overcrowding and delays. Rich Carden introduced the HITMAN mnemonic—Hygiene and Hydration, Infection, Tubes, Medication, Analgesia, and Nutrition—as a framework for managing patients who are stuck in the ED for extended periods.

The HITMAN approach ensures that patients' fundamental needs are met even when resources are stretched. This method helps prevent complications and improves patient outcomes, even in less-than-ideal conditions. The approach is particularly relevant in today’s healthcare environment, where EDs are often overwhelmed and patients may wait longer than usual for admission or transfer.

Atrial Fibrillation: Reassessing Cardioversion Strategies

Atrial fibrillation (AF) management was another key topic. A recent study in the New England Journal of Medicine compared immediate cardioversion with a wait-and-see approach in patients with new-onset AF. The study found that a wait-and-see approach was non-inferior to immediate cardioversion, with 69% of patients in the wait-and-see group spontaneously cardioverting within 48 hours.

This finding challenges the traditional approach of immediate cardioversion and suggests that in many cases, a more conservative approach may be just as effective. However, the decision should be made through shared decision-making with the patient, taking into account their preferences and the specific circumstances of their condition. This patient-centered approach ensures that treatment decisions are made collaboratively and with the patient’s best interests in mind.

Traumatic Cardiac Arrest: Reevaluating Chest Compressions

The podcast also touched on the evolving management of traumatic cardiac arrest, particularly the role of chest compressions. Recent studies, including one involving porcine models, suggest that in cases of hypovolemic traumatic cardiac arrest, chest compressions may not be beneficial and could even be harmful. Instead, the focus should be on addressing the underlying cause, such as restoring circulating volume.

This shift in practice highlights the importance of understanding the specific etiology of cardiac arrest and tailoring resuscitation efforts accordingly. Communicating these changes to the entire resuscitation team is crucial, as there may be resistance to deviating from traditional protocols. Ensuring that everyone is on the same page and understands the rationale behind the approach is key to successful implementation.

Virtual Reality in Pain Management: An Emerging Tool

Virtual reality (VR) is emerging as a promising tool in pain management, particularly in pediatric patients undergoing painful procedures. A recent study discussed in the podcast found that children who used VR experienced less distress during procedures compared to those who received standard care.

VR offers an innovative, accessible method for managing pain and anxiety, and its use is likely to expand in the coming years. The ability to create immersive environments that distract patients during procedures has the potential to improve patient experiences and outcomes, not just in children but potentially in adults as well.

The Power of Peer Review: Enhancing Clinical Practice

Finally, Simon Carley discussed the importance of peer review in clinical practice. Peer review is a valuable tool for continuous improvement, allowing clinicians to receive feedback from colleagues on their performance. While it can be challenging to create a culture where feedback is welcomed and constructive, the benefits are significant.

Peer review helps clinicians avoid complacency, stay up-to-date with best practices, and continually refine their skills. It’s a simple, cost-effective way to ensure that healthcare professionals are delivering the highest standard of care. Creating a supportive environment where feedback is seen as an opportunity for growth rather than criticism is essential for the success of peer review initiatives.

Conclusion

The discussions in this month’s St. Emlyn's podcast highlight the complexities and challenges of working in emergency medicine, from ensuring workplace safety to staying current with evolving practices. By engaging with new research, embracing innovative tools like virtual reality, and fostering a culture of continuous improvement through peer review, we can continue to advance the field and improve patient care. As always, the St. Emlyn's blog and podcast remain valuable resources for staying informed and connected with the latest developments in emergency medicine.

Highlights from March 2019: Key Insights and Updates

Welcome to the St Emlyn's podcast. I'm Simon Carley and today; I'll be taking you through the highlights from our blog in March 2019. This was a busy month filled with exceptional content, insightful trips, and significant conferences. Let's dive into the details and explore some key topics, starting with adult congenital heart disease, top trauma papers, and the importance of responsible volunteering.

Management of Adult Congenital Heart Disease

March kicked off with an important post on the management of adult congenital heart disease (ACHD). This topic is particularly close to my heart as the hospital I work at is a level two centre for ACHD in the UK. Services have become centralized, and surgical components are now managed at a few specialized centres, with Liverpool being the hub for my region.

Despite this centralization, we still encounter a large population of ACHD patients in our area. These patients often present complex medical histories and unique pathologies that can be challenging to manage in emergency settings. The guidance available typically focuses on chronic and surgical management, but emergency care for these patients requires a different approach.

Common Issues in ACHD Patients

ACHD patients commonly present with dysrhythmias, which can be particularly challenging to manage. Chest pain is also prevalent, although the incidence of ischemic heart disease isn’t significantly higher in ACHD patients, except for those who have undergone certain procedures like the switch operation. Other common issues include:

• Cyanotic patients: Those with single ventricle physiology and right-to-left shunts.
• Endocarditis: A rare but serious complication.
• Non-cardiac problems: Managing ACHD patients with conditions like appendicitis or pneumonia can be complex due to their unique circulatory dynamics.

The bottom line is that these patients often require specialized management strategies. When ACHD patients present with cardiac complications, we consult our local cardiologist or the ACHD centre. However, non-cardiac issues in ACHD patients also warrant discussion with the ACHD centre to ensure comprehensive care.

Key Takeaways for Emergency Physicians

Emergency physicians should familiarize themselves with the unique aspects of Fontan circulation, which relies on venous return based on venous pressure. Aggressive interventions like CPAP, bagging, and diuretics can be detrimental. Understanding these nuances is crucial for providing optimal care.

A Deeper Dive into Fontan Circulation

The Fontan procedure, a surgical intervention for single ventricle defects, creates a unique circulatory system that can be difficult to manage in emergency settings. Unlike normal circulation, Fontan physiology depends heavily on passive blood flow from the veins to the lungs. This means that increasing intrathoracic pressure through methods like CPAP or bagging can reduce cardiac output and worsen the patient's condition.

Fontan patients are particularly vulnerable to fluid shifts and pressures, making careful management of intravenous fluids and medications essential. Understanding these dynamics can be life-saving in the ED. For example, while diuretics might seem a reasonable choice for a patient with fluid overload, they can lead to dangerously low preload and cardiac output in a Fontan patient.

Top Trauma Papers from the Trauma UK Conference

Next up, we revisited some of the top trauma papers presented at the Trauma UK conference. These papers covered a range of topics, from the use of bougies in the ED to bag-mask ventilation during hypertensive resuscitation. Here are some key highlights:

The PAMPer Trial

The PAMPer trial examined the use of prehospital plasma in trauma patients and found significant survival benefits. This trial has important implications for trauma care protocols, emphasizing the potential of early plasma administration to improve outcomes.

The trial showed that administering plasma before hospital arrival can reduce mortality rates in severely injured patients. This finding supports the concept of damage control resuscitation, aiming to stabilize patients early and prevent coagulopathy, acidosis, and hypothermia—the lethal triad in trauma.

Bougie Use in the ED

Another focal point was the utility of bougies in emergency airway management. Evidence suggests that bougies can significantly improve first-pass success rates in difficult intubations, making them a valuable tool in the ED.

A study highlighted at the conference demonstrated that the use of a bougie, even in routine intubations, could increase the success rates for first-pass intubations. This is particularly important in prehospital settings and emergency departments where difficult airways are common.

Late Presenting Head Injury Patients

A paper from Hull explored the management of patients presenting with head injuries more than 24 hours post-injury. The findings indicated that these patients have a significant incidence of important findings on CT scans, suggesting that delayed presentations should not be underestimated.

This study challenges the conventional exclusion of late-presenting head injury patients from acute imaging protocols. It suggests that significant injuries can still be present and warrant immediate attention, even if the patient presents days after the initial trauma.

The Zero Point Survey

The Zero Point Survey, which emphasizes situational awareness, team dynamics, and environmental control before initiating the primary survey, was also highlighted. This approach can significantly enhance resuscitation efforts, ensuring a more organized and effective response.

The Zero Point Survey encourages clinicians to prepare mentally and physically before patient contact. By assessing the situation, assembling the right team, and ensuring the environment is conducive to optimal care, clinicians can improve outcomes and reduce errors in high-stress scenarios.

Responsible Volunteering Overseas

One of the most thought-provoking posts of the month came from Stefan Brisions, discussing the need for responsible volunteering overseas. Volunteering in low and middle-income countries can be incredibly rewarding, but it’s essential to approach it with the right mindset and framework.

The Ethics of Volunteering

Stefan emphasized the importance of volunteering within a system that has sustainability and benefits for all parties involved. There have been concerns about individuals volunteering for personal gain rather than genuine altruism. It’s crucial to ensure that our efforts are focused on creating lasting, positive impacts.

Volunteering should always aim to build local capacity rather than create dependency. This means working with local healthcare providers to enhance their skills and infrastructure, ensuring that the benefits of volunteering continue long after volunteers have left.

Volunteering Responsibly

If you're considering volunteering abroad, it’s vital to engage with established organizations that have a clear mission and ethical framework. This ensures that your contributions are meaningful and aligned with the needs of the local community. Our discussions with experts like Shweta Gidwani, Hooling Harrison, Jennifer Hulls, and Najee Rahman offer valuable insights into this complex issue.

Case Study: Volunteering in South Africa

Kat Evans, who works in Mitchell’s Plain in South Africa, shared her experiences at St Emlyn’s Live. Kat discussed the challenges of working in a resource-limited environment, particularly in managing trauma and toxicology cases.

Her insights into managing trauma in a high-volume, low-resource setting were eye-opening. Kat also shared fascinating details about the use of high doses of atropine for poisoning cases, highlighting the unique medical practices required in such environments.

Kat’s presentation underscored the value of structured volunteer programs that integrate volunteers into local healthcare systems, providing both valuable learning experiences and much-needed support to local healthcare providers.

The Future of SMACC: CODA

March also marked the end of an era with the final SMACC conference in Sydney. SMACC has been a cornerstone for many in the emergency and critical care communities, offering unparalleled opportunities for learning and networking. However, the spirit of SMACC lives on in its successor, CODA.

CODA: A New Beginning

CODA aims to build on SMACC's successes while addressing broader health issues such as vaccination, climate change, and healthcare inequality. The goal is to leverage the engaged community SMACC created to drive meaningful change on a global scale.

CODA plans to tackle these global health issues by bringing together a diverse group of professionals, including those outside the traditional medical fields. This interdisciplinary approach aims to create innovative solutions to some of the world’s most pressing health challenges.

Looking Ahead

While we bid farewell to SMACC, we look forward to the new opportunities CODA will bring. Its emphasis on tackling significant health challenges aligns with the evolving needs of the global healthcare community, promising an exciting future.

What to Expect from CODA

CODA will continue the tradition of high-quality content and dynamic presentations that SMACC was known for. However, it will also incorporate new elements focused on global health advocacy and interdisciplinary collaboration. Expect to see more discussions on how healthcare professionals can contribute to solving broader societal issues.

Additional Highlights from March

Critical Appraisal Nuggets (CANS) on P-values

We also introduced a mini podcast series called Critical Appraisal Nuggets (CANS) focusing on p-values, featuring myself and Rick Body. P-values are a common topic in exams and critical appraisal, and understanding them is crucial for interpreting medical research.

This less-than-ten-minute podcast provides a concise overview of p-values, helping clinicians and students alike grasp this important concept. By demystifying p-values, we aim to enhance our audience's critical appraisal skills, enabling better evidence-based practice.

Dual Coding in Medical Education

Nick Smith, a recent addition to the St Emlyn's team and a brilliant clinical educator, shared insights on dual coding. Dual coding involves using both verbal and visual information to enhance learning and retention.

Nick’s post emphasized how our brains struggle to process multiple streams of information simultaneously. Effective teaching and communication require a balance between verbal explanations and visual aids, ensuring that learners can absorb and retain information without being overwhelmed.

The Impact of Reboa in Trauma Care

Zaf Qasim, a great friend of ours over in the US, examined the impact of Resuscitative Endovascular Balloon Occlusion of the Aorta (Reboa) in trauma care. This post, based on a paper published in JAMA Surgery, analyzed Reboa success rates in civilian trauma using a US database.

The findings suggested that Reboa was associated with higher mortality rates compared to similar patients who did not receive Reboa. This raises important questions about patient selection and the overall benefits of Reboa in trauma care.

Zaf’s post highlighted the need for ongoing research and evidence to determine Reboa's true value. While there are compelling pathophysiological arguments for its use, the clinical outcomes must be scrutinized to ensure it is applied appropriately and effectively.

The Role of Evidence-Based Practice

At St Emlyn's, we prioritize evidence-based practice in all aspects of emergency medicine. The discussions around Reboa, p-values, and dual coding all reinforce the importance of using high-quality evidence to guide clinical decisions and educational strategies.

Understanding P Values: A Comprehensive Guide for Clinicians

Welcome to St Emlyn's blog, where we delve into the complex world of P values—a crucial element in medical research. For emergency medicine clinicians, understanding P values is essential for interpreting study results and applying them effectively in clinical practice. This post aims to demystify P values and enhance your critical appraisal skills.

What Are P Values?

P values are a measure of the probability that an observed difference could have occurred just by chance if the null hypothesis were true. The null hypothesis generally states that there is no difference between two treatments or interventions. Thus, a P value helps us determine whether the observed data is consistent with this hypothesis.

The Null Hypothesis and Significance Testing

To grasp P values fully, we start with the null hypothesis. In any trial, we begin with the premise that there is no difference between the treatments being tested. Our goal is to test this null hypothesis and ideally disprove it, a process known as significance testing.

When we calculate a P value, we express the probability of obtaining a result as extreme as the one observed, assuming the null hypothesis is true. For instance, a P value of 0.05 suggests a 5% chance that the observed difference is due to random variation alone.

The Magic of 0.05

The threshold of 0.05 has become a benchmark in research. A P value below this threshold is often considered statistically significant, while one above is not. However, this binary approach oversimplifies statistical analysis. The figure 0.05 is arbitrary and does not imply that results just above or below this threshold are vastly different in terms of practical significance.

Clinical vs. Statistical Significance

Distinguishing between statistical significance and clinical significance is crucial. A statistically significant result with a very small P value may not always translate into clinical importance. For example, a large study might find that a new treatment reduces blood pressure by 0.5 millimetres of mercury with a P value of 0.001. While statistically significant, such a small reduction may not be clinically relevant.

Conversely, a clinically significant finding might not reach the strict threshold of statistical significance, particularly in smaller studies. Therefore, it's essential to consider both the magnitude of the effect and its practical implications in clinical practice.

The Fragility Index

The fragility index is an alternative measure that addresses some limitations of P values. It calculates the number of events that would need to change to alter the study's results from statistically significant to non-significant. This index provides insight into the robustness of the findings. Surprisingly, even large trials can have a low fragility index, indicating that their results hinge on a small number of events.

Moving Beyond 0.05

Recognizing the limitations of the 0.05 threshold, some researchers advocate for more stringent criteria, such as a P value of 0.02, particularly in large randomized controlled trials (RCTs). This approach aims to reduce the likelihood of false-positive results and improve the reliability of findings. However, it also raises the bar for demonstrating the efficacy of new treatments, which can be a double-edged sword.

Multiple Testing and Bonferroni Adjustment

A significant challenge in research is multiple testing. Conducting numerous statistical tests increases the probability of finding at least one significant result purely by chance. This issue is particularly relevant in exploratory studies where multiple outcomes are assessed.

One method to address this problem is the Bonferroni adjustment, which adjusts the significance threshold based on the number of tests performed. While this approach helps control the risk of false positives, it can be overly conservative and reduce the power to detect true effects. Therefore, it should be used judiciously.

Interim Analysis in Clinical Trials

Interim analysis is a crucial aspect of clinical trials, allowing researchers to assess the effectiveness or harm of an intervention before the study's completion. However, performing multiple interim analyses can increase the risk of false-positive findings. To mitigate this risk, researchers use techniques like P value spending functions, which adjust the significance threshold for each interim analysis.

Additionally, the number of interim analyses should be limited and pre-specified in the study protocol. This ensures that decisions to stop a trial early are based on robust evidence and not on arbitrary or opportunistic analyses.

Effect Size and Confidence Intervals

P values alone do not provide a complete picture of the study results. It's equally important to consider the effect size, which measures the magnitude of the difference between treatments. A small P value might indicate statistical significance, but without a substantial effect size, the clinical relevance of the finding remains questionable.

Confidence intervals (CIs) complement P values by providing a range within which the true effect size is likely to lie. A 95% CI means that if the study were repeated multiple times, 95% of the calculated intervals would contain the true effect size. CIs offer valuable context for interpreting P values and understanding the precision of the estimated effect.

Practical Tips for Interpreting P Values

1. Understand the Null Hypothesis: Always start with a clear understanding of the null hypothesis and what the study aims to test.
2. Look Beyond the P Value: Consider the effect size, confidence intervals, and clinical significance of the findings.
3. Be Cautious with Multiple Testing: Recognize the increased risk of false positives with multiple comparisons and apply appropriate adjustments.
4. Assess the Fragility Index: Use the fragility index to gauge the robustness of the study's findings.
5. Consider Interim Analysis: Ensure that interim analyses are pre-planned and interpreted with caution to avoid bias.
6. Question the Threshold: Remember that the 0.05 threshold is not a magic number. Interpret P values in the context of the study design, sample size, and practical implications.

Conclusion

P values are a fundamental aspect of medical research, but their interpretation requires a nuanced understanding. By considering the null hypothesis, clinical significance, effect size, and confidence intervals, we can make more informed decisions based on the data. As emergency medicine clinicians, our goal is to apply research findings judiciously to improve patient care.

We hope this deep dive into P values has clarified their role and limitations in research. Remember, the journey to mastering statistical concepts is ongoing, and continuous learning is key.

A Deep Dive into December: The Best of St. Emlyn’s Blog and Beyond

Welcome to the St. Emlyn’s Podcast! I’m Simon Carley, and today we’re going to journey through December 2018. This month has been filled with intriguing discussions, significant insights, and top-notch blogs from a variety of experts. As we wrap up the year and get ready to welcome 2019, it’s the perfect time to reflect on the key topics that have shaped our discussions around Christmas and the New Year.

Tribalism in Healthcare with Ross Fischer

First up, we have an insightful contribution from Ross Fischer, a key member of the St. Emlyn’s team and a Pediatric Surgeon based in Sheffield. Ross has delved into the topic of tribalism in healthcare, a subject we've explored previously but which remains ever relevant.

Tribalism refers to the formation of groups or 'tribes' based on common beliefs and cultures, which significantly influences our behaviour and treatment approaches in healthcare. Ross's blog revisits a remarkable presentation by Vic Brazil at SMACC Gold in 2014, highlighting how tribalism drives our interactions and behaviours within the medical field.

In healthcare, tribes often form around specialities – emergency physicians, surgeons, anaesthetists, etc. While having a strong group identity can be positive, it can also lead to unhealthy competition and misunderstandings. For example, emergency physicians might unfairly label surgeons as uncooperative, which is not only untrue but also counterproductive.

Ross's extensive experience across various medical cultures has given him a unique perspective on this issue. His blog emphasizes the importance of recognizing and mitigating tribalism to foster better cooperation and ultimately improve patient care. Some strategies he suggests include using personal names during referrals, face-to-face communication, being supportive rather than critical when things go wrong, organizing social events across specialities, and calling out tribalism in casual conversations.

Conservative Management of Chest Trauma

Next, I’ve put together a blog on the conservative management of chest trauma, inspired by several presentations I've done this year on torso trauma. The increasing body of evidence suggests that not all chest injuries, such as hemothoraces and small pneumothoraces, require invasive intervention.

Reflecting on my early days in emergency medicine, we operated under the strict guideline that any pneumothorax or hemothorax warranted a chest drain. However, advances in imaging technology, like whole-body CT scans, have revealed that many small pneumothoraces and hemothoraces were previously undetected and thus untreated without significant complications.

Recent studies, including a substantial observational study by Walker, support the safety of conservative management for many of these cases. This shift in practice aligns with our experiences here in Virchester, where we often opt to observe rather than immediately intervene with chest drains, even in ventilated patients. The evidence is still evolving, but it’s encouraging to see data supporting less invasive approaches.

Intensive Care Insights with Dan Horner

Dan Horner, Professor of Emergency Medicine at Virchester West, has shared three exceptional posts from our time at the Intensive Care Society conference in London. The interface between emergency medicine and ICU is a critical area, and Dan’s insights are invaluable for anyone interested in this field.

One standout topic from the conference was Tom Evans' presentation on exercise physiology. Though I missed it, the demonstration with Olympic rowers on stage, showcasing their lactate levels, was reportedly phenomenal. This type of hands-on demonstration highlights the extraordinary resilience and adaptability of human physiology, insights that are crucial for both emergency and intensive care practitioners.

In addition to exercise physiology, Dan and I covered the continuum of patient care from the roadside to critical care, emphasizing the importance of effective handovers and collaborative work with paramedics. Our discussions included the zero point survey, ATMIST handovers, and the significance of follow-ups to ensure paramedics receive feedback on their patients' outcomes, all crucial elements for improving patient care and professional practice.

FemInEM Conference Highlights with Natalie May

Natalie May wrapped up our review of the FemInEM conference, emphasizing the multifaceted nature of medicine. The themes of passion, role models, organization, consistency, persistence, mentorship, and leadership were central to the conference discussions. FIX19, the upcoming FemInEM event, promises to continue this tradition of exploring how medical professionals can impact not just clinical outcomes but also their own lives, colleagues, and the broader community.

HIV Management in Emergency Medicine

Gareth Roberts, a recent addition to our consultant team in Manchester, provided a comprehensive review of HIV management from an emergency physician’s perspective. His blog focuses on post-exposure prophylaxis (PEP) and pre-exposure prophylaxis (PrEP), critical areas for emergency physicians to master.

With the ongoing changes in HIV treatment and prevention, understanding the nuances of PEP and PrEP is vital. Gareth also touches on the rise of chemsex and its implications for emergency medicine, emphasizing the need for awareness and appropriate management strategies for patients involved in these practices.

Trauma Laparotomy: A Decade of Data

Rich Cardens explored the intriguing findings from his PhD research on trauma laparotomy. Despite significant advancements in trauma care over the past decade, the mortality rate for trauma laparotomy has remained unchanged. This surprising discovery prompts a deeper investigation into the factors influencing these outcomes.

Rich's research compares data from the JTTR military registry and the Royal London Hospital, highlighting the need for a comprehensive trauma emergency laparotomy audit. Understanding why mortality rates haven't improved could lead to better strategies and practices in trauma care.

Game of Thrones Mortality Study

For a lighter, yet still educational note, Janos Byan Beethar found an entertaining yet insightful study in the Injury Prevention Journal. This study analyzed the mortality of characters in Game of Thrones, a bit of fun that doubles as a critical appraisal exercise. With over half of the 330 characters meeting untimely deaths through injury, burns, or poisoning, the study offers a unique way to engage with epidemiological concepts and cause-effect associations.

Interestingly, the study also suggests that characters who change allegiances have a higher survival rate – perhaps a subtle hint at the importance of adaptability in both fictional and real-world scenarios.

Looking Ahead to 2019

As we close out December, it’s clear that 2018 has been a year of growth, learning, and exciting developments here at St. Emlyn’s.

Navigating the Landscape of Emergency Medicine: Insights from St. Emlyn's

Welcome to St. Emlyn's, your go-to resource for the latest in emergency medicine. Our recent discussions cover a range of topics, from evolving communication strategies in major incidents to the nuances of managing chronic health issues among healthcare professionals. Let's dive into key insights and updates from our blog and the recent College of Emergency Medicine conference.

Modernizing Major Incident Communication

Traditionally, emergency departments relied on landlines and telephone trees for major incident alerts. However, modern digital tools like WhatsApp, Facebook, and Twitter offer more efficient solutions. Inspired by incidents like the Manchester bombing, our recent blog post details how to set up a robust communication system using WhatsApp. This involves configuring specific alert tones and ensuring confidentiality, providing a quick and reliable way to mobilize staff during crises.

Clots and Immobilization: Current Research and Practices

Clot management, especially in the context of immobilization, remains a critical area of study. Dan Horner's work, including the Tilly study, explores whether prophylactic low molecular weight heparins should be used for patients with injuries like Achilles tendon ruptures. Current guidelines suggest a nuanced approach, advocating for patient-specific discussions based on individual risk factors for DVT. This research highlights the importance of personalized treatment and continuous guideline updates.

The Role of Ultrasound in Managing Superficial Vein Thrombosis

The management of superficial vein thrombosis (SVT) has been another focus. Using ultrasound, as Dan Horner suggests, can help assess the extent of SVTs and determine the need for anticoagulation, particularly when SVTs are near the saphenofemoral junction. This approach ensures comprehensive care and prevents complications from missed DVT diagnoses.

Global Perspectives: Insights from South Africa

Our collaboration with UK physicians working in South Africa provides a global perspective on emergency medicine. Despite resource limitations, the dedication to delivering quality care remains consistent across continents. This exchange of knowledge reinforces the universal principles of emergency medicine, emphasizing adaptability and resourcefulness.

Addressing Chronic Health Conditions in the Workplace

A guest post by Harriet, a Manchester-based emergency physician with rheumatoid arthritis, offers insights into managing chronic health issues while working in emergency medicine. Harriet's story highlights the physical demands of the job and the need for supportive workplace practices. It encourages a more inclusive approach, ensuring that all healthcare professionals can perform at their best, regardless of health challenges.

Re-Evaluating Oxygen Therapy in Acute Coronary Syndromes

Evidence-based medicine is at the heart of St. Emlyn's, and the DETO2X-AMI study has sparked significant discussion. This study suggests that supplemental oxygen may not always benefit patients with acute coronary syndromes, particularly those with normal oxygen saturation levels. This finding prompts a more tailored approach to patient care, aligning treatments with the latest evidence.

The Emergence of New Cardiac Biomarkers

Cardiac myosin-binding protein C has emerged as a promising new marker for early myocardial infarction diagnosis. However, Rick Body cautions that despite its potential, the transition from research to clinical practice involves numerous hurdles. The practical application of new biomarkers requires rigorous testing and regulatory approval.

Revisiting Tetanus Management

Chris Gray's exploration of tetanus management emphasizes the need for accurate administration of vaccinations and immunoglobulin. Despite being a well-known disease, misunderstandings about treatment protocols persist. Chris's post clarifies who needs boosters and who requires immunoglobulin, ensuring patients receive appropriate care.

Lessons from Mass Casualty Incidents

Zafira Kasim’s insights from the AAST meeting highlight critical lessons from mass casualty incidents like the Florida nightclub shooting and the Boston bombings. These experiences underline the importance of preparedness and the continuous updating of major incident protocols. The blog post provides practical strategies for refining emergency response plans.

The State of Emergency Medicine in the UK

The recent College of Emergency Medicine conference in Liverpool provided a comprehensive overview of the state of the specialty in the UK. Despite challenges like burnout and systemic pressures, the conference showcased a resilient and dedicated community. Presentations highlighted the importance of mental health, resilience, and compassion in maintaining quality care. Caroline Leach’s discussion on compassion underscored the emotional journey of healthcare professionals and the need for empathy in the workplace.

The Need for More Academic Involvement

The conference also stressed the importance of increasing academic involvement in emergency medicine. The UK currently has a low number of emergency medicine professors compared to other specialties. There is a strong call to foster the next generation of academic leaders, with initiatives like new NIH positions offering opportunities for growth.

In this episode of the St Emlyn's podcast, Ian Beardsell and Simon Carley review the top 10 trauma papers of the year, highlighting key findings and their implications for trauma care. The selection includes significant studies published in high-profile journals such as The Lancet and the New England Journal of Medicine, offering valuable insights for healthcare professionals in emergency and trauma medicine.

1. Whole Body CT Scanning: REACT-2 Study

The REACT-2 study explored the impact of whole-body CT (WBCT) scanning on trauma patients, particularly its effect on mortality rates. The study involved 1400 patients and found no significant difference in mortality between those who received WBCT and those who underwent more selective CT scanning. The difference in radiation exposure was minimal, suggesting that WBCT's comprehensive imaging might be more beneficial than harmful, especially in elderly patients where missed injuries can complicate outcomes. This study reassures trauma team leaders that current scanning practices are appropriate and highlights the importance of a patient-centred approach based on clinical presentation.

2. Impact Brain Apnea (IBA)

Impact brain apnea, characterized by apnea and a catecholamine surge following a severe head blow, has been increasingly recognized in trauma care. The paper, co-authored by John Hines and Mark Wilson, provides a detailed explanation of IBA's pathophysiological mechanisms. This condition can lead to cardiac arrest if not promptly addressed, emphasizing the need for immediate intervention in cases of traumatic brain injury (TBI). Understanding IBA helps emergency care providers identify and treat potentially life-threatening conditions that may not be immediately apparent.

3. Decompressive Craniectomy for Raised ICP: RESCUE-ICP Trial

The RESCUE-ICP trial examined the outcomes of decompressive craniectomy in patients with refractory intracranial pressure (ICP) due to severe TBI. The study found that while the procedure increased survival rates, many survivors experienced significant disability. This raises ethical considerations about the quality of life post-intervention. The trial underscores the importance of informed consent and discussions about potential outcomes with patients' families, aligning treatment with patient values.

4. STITCH Trial: Surgery Timing for Intracranial Bleeds

The STITCH trial focused on the timing of surgical intervention in patients with traumatic intracranial bleeds. Although the trial faced recruitment challenges and was terminated early, results suggested better outcomes with early surgery. This finding, while not statistically conclusive, supports the notion that timely intervention can reduce mortality and improve recovery. Emergency physicians and neurosurgeons should consider these findings when deciding on surgical timing in TBI cases.

5. Traumatic Cardiac Arrest: Epidemiology and Outcomes

Using data from the Trauma Audit and Research Network (TARN), this study examined traumatic cardiac arrest (TCA) cases, revealing a 30-day survival rate of 7.5%. This rate, similar to medical cardiac arrests, challenges the perception that TCA is almost always fatal. The study highlights the importance of aggressive resuscitation efforts and underscores the need for ongoing training to retain skills in managing these rare but critical events.

6. Open vs. Closed Chest Compressions in TCA

The effectiveness of open chest (thoracotomy) versus closed chest compressions in TCA was explored, with findings indicating similar outcomes in terms of end-tidal CO2 levels, a marker for effective CPR. This challenges the notion that thoracotomy should always be performed in TCA cases. The study suggests that standard advanced life support (ALS) protocols may suffice in certain scenarios, especially where thoracotomy is not practical.

7. Rocuronium vs. Succinylcholine for RSI in Severe Brain Injury

The choice between rocuronium and succinylcholine for rapid sequence intubation (RSI) in severe brain injury remains debated. An observational study found no significant overall difference in mortality between the two drugs, though succinylcholine was associated with higher mortality in severe head injury cases. This suggests a possible preference for rocuronium in such scenarios, though the evidence is not strong enough to mandate a change in practice.

8. Intraosseous Needle Length in Obese Patients

As obesity becomes more prevalent, appropriate intraosseous (IO) needle length is crucial for effective vascular access. The study recommended using longer yellow IO needles for patients with a BMI over 43, as standard blue needles may not reach the marrow. This is particularly important in emergency situations where IV access is difficult, ensuring proper drug administration and preventing complications like compartment syndrome.

9. Optimal Site for Needle Decompression in Tension Pneumothorax

A systematic review recommended the anterior axillary line as the preferred site for needle decompression in tension pneumothorax, aligning with standard chest drain placement. The review also noted significant complication rates associated with needle decompression, suggesting that alternative methods like thoracostomy may be necessary in certain cases. This finding emphasizes the need for precise technique and careful consideration in managing tension pneumothorax.

10. Weekend Effect in Major Trauma Care

The study examined the "weekend effect" in major trauma care, finding no significant difference in mortality between weekend and weekday admissions. This suggests that well-resourced, consultant-led trauma care can provide consistent outcomes regardless of the day. The findings advocate for the 24/7 availability of senior emergency physicians and trauma teams, ensuring high-quality care at all times.

Conclusion

This year's top trauma papers provide valuable insights into current practices and emerging trends in trauma care. While there may not have been groundbreaking changes, the studies reinforce the importance of evidence-based decision-making, ongoing training, and ethical considerations in patient management. As the field evolves, staying informed about the latest research is crucial for improving patient outcomes and delivering high-quality trauma care.

Summary of Selection Bias in Medical Research

Introduction

Selection bias is a critical issue in medical research that can undermine the validity of study findings. It occurs when there is a systematic difference between the study population and the broader population the research aims to represent. Understanding selection bias is essential for clinicians and researchers, as it can lead to questionable conclusions and affect clinical practice. This summary covers the definition of selection bias, its sources, and ways to mitigate it, along with a case study illustrating its impact.

What is Selection Bias?

Selection bias happens when the participants in a study do not accurately reflect the general population. This discrepancy can result from various factors, including how patients are selected, the setting of the study, and the timing of patient recruitment. Such biases can skew research results, making them less applicable to real-world situations. As medical professionals rely heavily on research to inform clinical decisions, recognizing and addressing selection bias is crucial.

Sources of Selection Bias

1. Study Environment

   The environment where a study is conducted can significantly influence patient selection. For instance, patients in a general practitioner's office might have a lower prevalence of serious conditions compared to those in an emergency department. Additionally, studies in specialized tertiary care centers often include patients with more severe or rare conditions, which may not represent the general patient population. This can lead to overestimating or underestimating the effectiveness of treatments or the accuracy of diagnostic tests.

2. Timing of Patient Recruitment

   The timing of patient recruitment is another source of selection bias. The stage of illness at which patients are recruited can affect study outcomes, especially in diagnostic studies. For example, the diagnostic value of CRP for appendicitis changes depending on when it is measured. Additionally, certain conditions may present differently depending on the time of day or week, potentially leading to an incomplete understanding of a condition's prevalence or severity if the study only includes patients from specific times.

3. Retrospective vs. Prospective Studies

   Retrospective studies, which rely on historical data, are particularly vulnerable to selection bias. These studies may selectively include data from periods with better patient outcomes, leading to skewed results. They may also suffer from incomplete data or changes in diagnostic criteria over time, making it difficult to generalize findings. Prospective studies, while more controlled, also need careful planning to avoid selection bias, especially in defining inclusion and exclusion criteria.

4. Convenience Sampling

   Convenience sampling involves selecting patients based on availability rather than a structured protocol, often due to resource limitations. This can result in a non-representative sample, such as including only daytime patients who might differ from those presenting at night. While convenience sampling can be a pragmatic choice, it often leads to underrepresentation of certain patient groups, potentially biasing study findings.

Mitigating Selection Bias

To mitigate selection bias, researchers should strive for comprehensive sampling strategies, such as random or consecutive sampling. Where complete sampling is not possible, they should transparently report potential biases and the measures taken to minimize them. For instance, using screening logs or adjusting for demographic differences can help address disparities between recruited and non-recruited patients. Sensitivity analyses can also be used to understand the impact of excluding certain patient groups.

Case Study: Thrombolysis in PEA Cardiac Arrest

A recent journal club discussion highlighted a retrospective cohort study by Shereefi et al., examining the efficacy of half-dose thrombolysis in patients with PEA cardiac arrest and confirmed pulmonary embolism (PE). The study raised concerns due to several potential biases. The arbitrary selection of a 23-month inclusion period, without a clear rationale, suggests the possibility of survival bias, as it included only patients who survived long enough to receive a confirmatory diagnosis of PE. This selective inclusion means the findings might overestimate the treatment's effectiveness, as the study only considered patients with a relatively favorable prognosis.

Moreover, the study's setting in a specialized environment and the inclusion of only confirmed PE cases limit the generalizability of the results. In practice, thrombolysis may be administered based on clinical suspicion rather than confirmed diagnosis, which involves a broader and potentially more diverse patient group. The study's focus on survivors also excludes those who may have died before a diagnosis, further skewing the data towards more favorable outcomes.

Implications of Selection Bias

Selection bias can significantly impact the interpretation of study results and, consequently, clinical decisions. It can lead to over- or underestimation of a treatment's effectiveness or the prevalence of a condition. This bias can also affect healthcare policy and practice guidelines, potentially disadvantaging underrepresented patient groups. For example, guidelines developed from biased research may fail to address the needs of older adults or those with comorbidities if these groups are underrepresented in studies.

Conclusion

Selection bias is a pervasive issue that can undermine the credibility of medical research. It arises from various sources, including the study environment, timing of recruitment, study design, and sampling methods. While complete elimination of selection bias is challenging, awareness and careful methodological design can mitigate its effects. Researchers and clinicians must critically appraise studies, considering potential biases and their implications for clinical practice. By doing so, we can make more informed decisions and improve patient care. At St. Emlyns, we continue to explore these critical appraisal topics to support evidence-based practice.

Introduction

Welcome to the St. Emlyn's induction podcast recap, where we dive deep into the management of asthma in the emergency department. Asthma is a prevalent condition that emergency medical professionals encounter frequently. This blog post will provide a detailed step-by-step guide to managing patients presenting with asthma, including case presentation, assessment, treatment, and discharge planning. Whether you're a seasoned practitioner or new to emergency medicine, this guide aims to enhance your understanding and improve patient outcomes.

Case Presentation: Recognizing Severe Asthma

Imagine you're in the resuscitation room when you're alerted about an incoming patient. A 30-year-old female with a history of acute severe asthma is being brought in. She's a smoker, consuming 20 cigarettes a day, and has had a history of hospital admissions, including an ICU stay a few years ago. As she is wheeled in, you notice she is short of breath with audible wheezing. This initial presentation provides critical information for immediate action.

First Steps: Rapid Assessment and Initial Management

Upon the patient's arrival, it's crucial to make a rapid assessment. Conducting an ABC (Airway, Breathing, Circulation) assessment is essential to confirm the diagnosis and gauge the severity of the asthma attack. Given the patient's severe condition, it's vital to start treatment immediately while continuing your assessment.

Immediate Actions

1. High-Flow Oxygen: Administer high-flow oxygen to improve oxygen saturation levels.
2. Nebulizers: Start with 5 mg of salbutamol and 500 mcg of ipratropium bromide. Don't hesitate to administer another dose if needed.
3. Listen to the Chest: A quick auscultation of the chest can help confirm the presence of wheezes and rule out other conditions like tension pneumothorax.

Understanding the Severity of Asthma

Assessing the severity of asthma is critical to guiding further treatment. The British Thoracic Society provides guidelines that classify asthma into mild, moderate, acute severe, and life-threatening categories.

Criteria for Severity

1. Mild Asthma: Patients might experience mild dyspnea but can generally manage with minimal intervention.
2. Moderate Asthma: Characterized by a peak flow more than 50% of predicted or best, moderate symptoms, and manageable at home with proper medication.
3. Acute Severe Asthma: Marked by a peak flow below 50%, respiratory rate over 25, heart rate over 110, or an inability to complete sentences.
4. Life-Threatening Asthma: Includes a peak flow less than 33%, low oxygen saturation below 92%, silent chest on auscultation, cyanosis, and signs of exhaustion.

Continuous Management: Treating Severe Asthma

In cases of severe or life-threatening asthma, continuous management and close monitoring are paramount.

Back-to-Back Nebulizers

Administering nebulizers continuously can help manage severe bronchoconstriction. Use salbutamol and ipratropium bromide back-to-back to provide relief.

Steroid Administration

Steroids play a crucial role in managing asthma by reducing inflammation. Administer oral steroids (1-2 mg/kg of prednisolone) or intravenous steroids if oral administration is not feasible.

Intravenous Bronchodilators

Consider intravenous bronchodilators like salbutamol if nebulized drugs are ineffective. Prepare IV salbutamol early to ensure it's available when needed.

Magnesium Sulfate

Magnesium sulfate can be considered in severe cases. Although recent studies suggest it might not significantly impact, it is relatively safe and may benefit a small subgroup of patients.

Advanced Interventions: When Initial Treatments Fail

If the patient's condition does not improve with initial treatments, advanced interventions may be necessary.

Critical Care Consultation

Engage with critical care colleagues early if the patient requires intensive care or ventilation. Ventilating an asthmatic patient is complex and requires experienced personnel.

Additional Therapies

1. Ketamine Infusion: Ketamine can act as a bronchodilator and is used in managing severe asthma.
2. CPAP: Continuous Positive Airway Pressure (CPAP) can be used in cases of severe air trapping and respiratory distress.

Importance of Senior Support

It's vital for less experienced doctors to seek senior help when managing severe asthma cases. These patients require the most experienced care available.

Discharge Planning: Ensuring Safe Transition

For patients showing improvement, careful discharge planning is essential to prevent relapse and ensure ongoing management.

Criteria for Discharge

1. Stability: Ensure the patient is stable for at least 6-8 hours after initial treatment.
2. Follow-Up: Arrange follow-up with a general practitioner or asthma nurse within a few days.
3. Medication Review: Ensure the patient has access to their inhalers and understands their use.
4. Safety Netting: Advise the patient to return if symptoms worsen, even if they are already on their way home.

Safety Measures

Natalie May from St. Emlyn's emphasizes the importance of advising patients to return if they have any concerns, even after leaving the hospital. Ensuring patients have their therapy and understand their treatment plan is crucial for safe discharge.

Conclusion: Recap and Key Takeaways

In summary, managing asthma in the emergency department requires a systematic approach:

1. Rapid Assessment: Quickly assess the severity using ABC and confirm the diagnosis.
2. Immediate Treatment: Administer high-flow oxygen and nebulizers without delay.
3. Continuous Management: Use back-to-back nebulizers, steroids, and consider IV bronchodilators and magnesium sulfate.
4. Advanced Interventions: Engage critical care and consider additional therapies like ketamine and CPAP.
5. Discharge Planning: Ensure the patient is stable, arrange follow-up, review medications, and provide safety netting advice.

Asthma management in emergency settings is challenging but manageable with the right approach and timely interventions. Always prioritize the patient's safety and seek senior support when needed.

Rapid Assessment: ABC Approach

1. Airway: Ensure the airway is clear. Asthma patients typically do not have airway obstructions, but it is crucial to check for any foreign bodies or swelling that might complicate the condition.

2. Breathing: Assess the patient's breathing. Look for signs of respiratory distress, such as rapid breathing, use of accessory muscles, and the presence of wheezing. Measure oxygen saturation using a pulse oximeter.

3. Circulation: Check the patient's heart rate and blood pressure. Asthma can cause tachycardia and hypertension due to the stress of breathing difficulties.

Initial Actions

1. Administer High-Flow Oxygen: The first and most crucial step is to administer high-flow oxygen. This intervention aims to improve the patient's oxygen saturation levels. Use a non-rebreather mask to deliver a high concentration of oxygen (usually 15 liters per minute).

2. Start Nebulizers: Administer bronchodilators through a nebulizer. Begin with 5 mg of salbutamol and 500 mcg of ipratropium bromide. These medications help to relax the bronchial muscles and reduce bronchospasm, facilitating easier breathing. If the patient remains symptomatic, additional doses can be administered without hesitation.

3. Listen to the Chest: Perform a quick auscultation of the chest to confirm the presence of wheezes and rule out other conditions such as a tension pneumothorax. The presence of bilateral wheezing supports the diagnosis of an asthma exacerbation.

Understanding Asthma Severity

Assessing the severity of the asthma attack is essential for guiding treatment decisions. The British Thoracic Society classifies asthma into mild, moderate, acute severe, and life-threatening categories based on specific clinical criteria.

Severity Criteria

1. Mild Asthma: Patients with mild asthma may experience mild dyspnea and can usually manage with minimal intervention.

2. Moderate Asthma: Characterized by a peak flow more than 50% of predicted or best, moderate symptoms, and manageable with proper medication at home.
