Ep 245 - Leading through failure with Kevin Cyr at Tactical Trauma 2024

Recorded at Tactical Trauma 2024, in this episode of the St. Emlyn’s podcast, Iain Beardsell and Liz Crowe sit down with Kevin Cyr, commander of a SWAT-like unit in the Royal Canadian Mounted Police, to discuss leadership, failure, and resilience in high-stakes environments. Kevin shares the powerful story of a tragic hostage situation that resulted in the unintended death of the hostage by the police, a failure of the highest order. Through this  tragedy, Kevin highlights the importance of visible leadership, team resilience, and learning from failure in both law enforcement and healthcare settings.

Key Themes:

1. Handling Failure in High-Pressure Situations:
Kevin discusses a significant incident where a hostage was killed by his SWAT team during a rescue attempt, describing it as the “epitome of failure.” This tragic event not only made national news but left an indelible mark on the team. The podcast dives into the lessons learned from this event and how the team used it to drive growth and improvement. In healthcare, much like in policing, failure can feel devastating and highly public, but it’s also a critical aspect of development for teams and leaders.

2. Visible Leadership and Unwavering Support:
In the aftermath of a traumatic event, Kevin emphasizes the importance of leadership being present and supportive. He recounts how he and his commanding officer went to visit the officers involved in the shooting immediately after the event, providing what he calls “unwavering support.” In healthcare, leaders should adopt similar strategies, offering visible and sustained support to their teams in the immediate aftermath of difficult cases.

3. Sustained Support Over Time:
While initial support following a traumatic event is crucial, Kevin points out that it’s often after 48 hours, or even weeks later, that people start feeling isolated. Leaders must continue to check in with their teams weeks after the event, when the immediate crisis may have passed, but the emotional toll is still present. This ongoing visibility and emotional support are key to retaining staff and ensuring their well-being in both law enforcement and healthcare.

4. Debriefing to Learn, Not to Blame:
Kevin advocates for a debriefing process that focuses on learning from failure rather than assigning blame. After their tragic event, his team didn’t just move on; they dissected the event to understand what went wrong and how to prevent similar failures in the future. In healthcare, this process is equally valuable—debriefs should aim to identify learning opportunities and reinforce positive actions, not to point fingers.

5. The Role of Organizational Culture:
Kevin touches on how organizational apathy, or a lack of emotional and psychological support, can cause more damage than the actual traumatic event itself. He highlights the importance of developing a high-trust environment where team members feel safe to express vulnerability. In healthcare, fostering a culture of open communication and mutual support is essential to prevent burnout and moral injury.

6. The Value of Failure in Team Growth:
One of the most profound insights Kevin shares is the idea that failure is a necessary part of growth. Three years after their tragic hostage situation, his team was called to a similar event, but this time they were successful in rescuing both hostages. Kevin attributes this success directly to the lessons learned from their earlier failure, emphasizing that failure, when handled correctly, can lead to transformational change.

7. Selection and Resilience in High-Performance Teams:
Kevin discusses the importance of selecting team members with high emotional intelligence and the humility to ask for help when needed. He explains how his team differentiates between rank and role, giving autonomy to those with the most subject matter expertise, regardless of their rank. In healthcare, this is a critical point—leaders must recognize that true leadership isn’t just about authority, but about empowering others to take charge when appropriate.

8. Managing Expectations and Mental Health:
The episode also delves into how individuals in high-stakes roles, whether in policing or healthcare, cope with the psychological aftermath of traumatic events. Kevin explains how his team has shifted from the belief that emotional support is unnecessary to recognizing the value of helping team members process their experiences in a healthy way. This parallels the increasing focus in healthcare on preventing burnout and ensuring emotional well-being through proactive support.

Key Takeaways:

- Failure is Inevitable: In high-stakes environments like policing and healthcare, failure will happen. What matters is how teams respond to failure—learning from it, growing stronger, and preventing future mistakes. Leadership Requires Visibility: Leaders must be present, especially in the aftermath of failure. Showing unwavering support and maintaining visibility over time is crucial for maintaining team morale and trust.

- Debriefing to Learn: After a failure, it’s essential to have structured debriefs that focus on learning and improving, rather than blaming. This helps teams identify areas of improvement and ensures they grow stronger from difficult experiences.

- Long-Term Support is Critical: Immediate support after a traumatic event is important, but equally important is sustaining that support over time, checking in with team members weeks or even months later to ensure their well-being.

- Resilience through Humility: Teams should be built on trust and humility, where members can ask for help when needed and offer help to others. Selecting individuals with high emotional intelligence is key to creating a resilient team.

- Failure Leads to Growth: When handled correctly, failure can drive transformational change within teams. It allows for the development of new skills and ensures that teams are better prepared for future challenges.

Quotes:

- “Failure is a necessary part of growth. It’s not just something to get over, it’s something you get better from.”
- “Visible leadership and unwavering support are critical in the immediate aftermath of failure. Your team needs to know you’re there with them.”
- “Debriefing to learn, not to blame, is essential. We must focus on what went well, what went wrong, and how to improve next time.”
- “In high-pressure environments, we can’t control every variable, but we can control how we respond to them and how we prepare for the future.”

 

Ep 244 - July 2024 Monthly Update - Chest Pain, REBOA, Lidocaine patches and lots of paediatric emergency medicine

Welcome back to the St. Emlyn’s podcast. This episode covers some of the most important developments in emergency medicine and critical care from July 2024. Whether you're practicing on the frontlines or keeping up with the latest research, this episode has something for you. From coronary risk scoring tools to cutting-edge AI in ECG interpretation, and the management of non-fatal strangulation, it’s packed with insightful updates. Here's a breakdown of the key topics:

The Manchester Acute Coronary Score (MACS Rule) is a valuable tool for risk-stratifying patients presenting with chest pain in the emergency department (ED). MACS uses both clinical characteristics and biomarkers like troponin to assess a patient's likelihood of experiencing an acute coronary event. A recent systematic review found that the T-MACS model (which uses troponin) has a sensitivity of 96%, making it highly effective at ruling out serious coronary events.

Though the specificity is lower, MACS’s real strength lies in its ability to drive clinical decisions and patient referrals. This tool is already integrated into the Electronic Patient Record (EPR) in Manchester, where it helps streamline the decision-making process for patients with chest pain. If you’re looking for a reliable method to quickly and accurately stratify risk, MACS could be the answer.

Artificial intelligence (AI) is revolutionizing healthcare, and its application in ECG interpretation is particularly exciting for emergency medicine. In this episode, Steve Smith joins us to talk about how AI can enhance the detection of occlusive myocardial infarction (OMI)—a concept that might one day replace the traditional ST-elevation and non-ST-elevation classifications.

By integrating AI into rapid assessment areas (like pit-stop zones in the ED), clinicians can benefit from real-time ECG analysis. This reduces the burden of interruptions and helps detect subtle abnormalities that might be missed in high-pressure environments. AI-driven ECG tools could dramatically improve patient outcomes, particularly in cases of high-risk cardiac events.

Non-fatal strangulation (NFS) is an often underdiagnosed condition in emergency medicine, but it carries significant risks, including carotid artery dissection. A new guideline from the Faculty of Forensic and Legal Medicine emphasizes the importance of detecting these cases and suggests that clinicians use contrast angiography to rule out vascular injuries.

Beyond the medical consequences, non-fatal strangulation is also a major indicator of future violence, including homicide. The guideline highlights the ethical challenges clinicians face when deciding whether to involve law enforcement, especially when patient consent is lacking. Safeguarding and appropriate referrals are essential for these high-risk patients.

REBOA has been evolving in recent years, and now it’s moving from the emergency department into the pre-hospital setting. In the latest advancements, partial REBOA—which allows for some blood flow below the balloon—is being used to resuscitate patients in traumatic cardiac arrest.

This partial occlusion technique may be more effective in maintaining coronary perfusion, essentially resuscitating the heart in cases of extreme hemorrhage. Early data from a feasibility study shows promise, with an 18% survival rate in patients who otherwise would have had little chance of survival. REBOA could become a life-saving pre-hospital intervention for trauma patients in the near future.

Paediatric eating disorders, particularly anorexia and diabulimia, remain under-recognized in emergency medicine. In this episode, we explore some of the red flags—such as rapid weight loss, bradycardia, and postural hypotension—and why emergency clinicians need to be more attuned to the signs of eating disorders.

Of all mental health disorders, anorexia has the highest mortality rate, and in cases of diabulimia, patients intentionally stop taking insulin to induce ketosis and lose weight. Given the severity of these conditions, it's crucial that we recognize them early and respond appropriately, especially when young diabetic patients present with unusual symptoms.

The advent of hybrid closed-loop insulin pumps is transforming the care of type 1 diabetes. These pumps act as an artificial pancreas, continuously monitoring blood glucose levels and adjusting insulin delivery automatically. The latest guidelines from NICE recommend these devices for all patients with type 1 diabetes in the UK.

However, these pumps come with their own set of challenges, especially in the emergency department, where clinicians need to know how to troubleshoot common problems, such as cannula blockages or starvation ketosis. In this episode, Nicola Trevelyan walks us through the essential steps for managing patients who use these devices.

Lidocaine patches have long been used as a low-risk intervention for managing pain in elderly patients with rib fractures, particularly when nerve blocks or NSAIDs aren’t viable options. But how effective are they? A recent feasibility study compared lidocaine patches with standard care and found that while the pulmonary complication rate remains high, the patches may offer some benefit for pain relief.

While more research is needed, lidocaine patches continue to be a low-harm option that might provide relief in certain patient populations, particularly where other pain management strategies are contraindicated.

Button battery ingestion remains one of the most dangerous emergencies in pediatric medicine. Francesca Stedman, a pediatric surgeon, explains the dangers of battery-induced burns, which can occur within hours of ingestion. Time is of the essence in these cases, and quick identification through radiographic imaging followed by rapid removal is critical to prevent long-term damage.

Even when batteries are lodged in places like the nose, they can cause significant tissue damage in a short time, making early intervention absolutely vital.

That’s a wrap for our July 2024 podcast update! From life-saving interventions like REBOA and AI in ECG analysis to the everyday challenges of managing pediatric emergencies and coronary risk, this month’s highlights offer a wealth of knowledge for clinicians. Be sure to check out the full blog posts and podcasts for more in-depth discussions on each of these topics. Thanks for listening and stay tuned for more cutting-edge insights from St. Emlyn’s!

Ep 243 - The Subarachnoid Haemorrhage in Emergency Department (SHED) Study

In this episode of the St Emlyn's podcast, Iain Beardsell is joined by Dan Horner, a consultant in Emergency Medicine and Neurocritical Care, and Tom Roberts, an Emergency Medicine Registrar and clinical lecturer, to discuss their recently published SHED study on subarachnoid haemorrhage in the Emergency Department (ED). This landmark study, published in the Emergency Medicine Journal, explores the safety of CT scans in diagnosing subarachnoid haemorrhage up to 24 hours after headache onset and evaluates the role of further investigations like a lumbar puncture.

The study examines acute severe headache presentations in the ED and the diagnostic approach to ruling out subarachnoid haemorrhage, a critical and often feared diagnosis among emergency physicians. Conducted through the Trainee Emergency Research Network (TURN), the study included over 3,600 patients from 88 UK EDs with acute severe headaches reaching maximum intensity within one hour and no focal neurology. Data collection included CT scans, lumbar puncture results, and 28-day follow-up to identify missed cases of subarachnoid hemorrhage.

Key findings from the study revealed a 6.5% prevalence of subarachnoid haemorrhage, with a significant number presenting within six hours of headache onset. The sensitivity of CT scans remained high beyond the traditional six-hour window, suggesting that CT alone could safely rule out subarachnoid haemorrhage up to 18 hours in many cases, potentially reducing the need for lumbar puncture. The risk of missing an aneurysmal subarachnoid haemorrhage after a negative CT was found to be extremely low, around 1 in 1,000.

These findings challenge the routine use of lumbar puncture in patients presenting beyond six hours if the CT scan is negative, potentially changing ED practice and reducing unnecessary invasive procedures. The discussion also emphasized the importance of shared decision-making and recognizing that diagnostic testing is about managing probabilities, not certainties. For clinicians, the episode highlights the need to expedite CT scans for patients with acute severe headaches, especially those presenting within 10 minutes of onset, as they are more likely to have significant pathology. Emergency physicians are encouraged to own the decision-making process for ruling out serious causes of headaches and not defer solely to 'specialists'.

The SHED study supports extending the diagnostic window for CT scans in ruling out subarachnoid hemorrhage up to 18 hours, reducing the need for lumbar puncture in many cases. This data empowers emergency clinicians to make informed decisions, manage patient expectations, and streamline ED processes. 

For more information, listeners are encouraged to read the SHED Study in the Emergency Medicine Journal and explore the related blog post on the St Emlyn’s website. Emergency clinicians are also invited to connect with TERN to get involved in future research opportunities. 

This episode provides valuable insights for clinicians in managing acute severe headaches, emphasizing a more nuanced approach to subarachnoid hemorrhage diagnosis and the importance of clinical decision-making in the ED.

Ep 242 - Prehospital Neuroprotection with Ed Langford at PREMIER 2024

Ep 241 - Paediatric Palliative Care with Tim Warlow at PREMIER 2024

In this episode, Dr Tim Warlow, a consultant in Paediatric Palliative Care, explores the complexities of caring for children with life-limiting conditions in the emergency department (ED). The discussion highlights the increasing prevalence of paediatric life-limiting conditions and the growing medical complexity of these cases, which pose significant challenges for ED staff.

The episode begins by clarifying what paediatric palliative care truly involves. Contrary to common misconceptions, palliative care is not about withdrawing care but rather enhancing the quality of life for children from the point of diagnosis, whether the condition is present from birth or develops as the child deteriorates. This proactive approach often involves increasing the level of care and support as the child’s needs evolve.

As the number of children with life-limiting conditions continues to rise, EDs are encountering more medically complex cases, including children who are technology-dependent and require high levels of care at home. These challenges are compounded by the evolving expectations of parents, who are often better informed and more involved in their child's care decisions. Post-COVID, community services have struggled to recover, particularly in nursing support, making the role of the ED even more critical.

The episode provides practical tips for ED professionals to better manage these cases. Key strategies include:

1. Recognising Life-Limiting Conditions: With over 400 recognized life-limiting conditions and many more undiagnosed, it’s crucial to assess whether a child might have palliative care needs.

2. Listening to Families: Families often have an intimate understanding of their child’s unique medical baseline. Listening deeply to their insights, even when they seem unusual, is essential for providing appropriate care.

3. Building Rapid Rapport: Quickly establishing a connection with the family is vital, as these children can deteriorate rapidly. Acknowledging the child’s presence, summarizing the situation, and validating the family’s experience can help build trust.

4. Understanding the Child Beyond Their Illness: Families worry that healthcare professionals only see their child when they are unwell. Taking the time to learn about the child’s life outside of the hospital can lead to better care decisions.

5. Reading the Advanced Care Plan: If available, review the child’s advanced care plan before discussing the case with the family. This ensures that the family doesn’t have to recount their entire journey and that care decisions are based on the most current information.

The episode also addresses the importance of being aware of unconscious prejudice. Healthcare professionals must ensure that decisions are based on the child’s specific needs rather than assumptions about their quality of life due to their disability.

In conclusion, the episode emphasizes that while caring for children with life-limiting conditions in the ED is challenging, it is also deeply rewarding. The key to providing excellent care lies not just in medical interventions but in being present, listening, and supporting the family through difficult times. Whether things go as planned or not, your presence and compassion are what families remember most.

This episode is a must-listen for anyone involved in pediatric care, offering valuable insights into the critical role of the ED in supporting children with life-limiting conditions and their families. There is more detail on the blogpost here.

Ep 239 - Button Battery Ingestion with Francesca Steadman at PREMIER 2024

In this podcast from the PREMIER conference 2024, Francesca Stedman, a consultant paediatric surgeon from Southampton Children's Hospital discusses the care of the child who has ingested a button battery. 

Button batteries are ubiquitous and come in various types and sizes. There are about 85 different kinds available or in use in the UK alone, found in everything from toys to hearing aids. The most notorious is the CR2032, which is about 20 millimeters in diameter and 3.2 millimeters thick. It contains lithium manganese oxide, and while its small size makes it convenient for electronics, it poses a significant risk if ingested.

The danger with button batteries lies in their potential to cause severe injuries when lodged in the esophagus. They can cause necrosis, which is essentially tissue death, due to a strong alkaline substance produced by the battery. This substance acts like a potent oven cleaner, rapidly causing damage. The esophagus has three natural narrowing points where these batteries often get stuck, increasing the likelihood of injury. The situation becomes critical very quickly, often within two hours of ingestion.

One of the most concerning aspects of these incidents is that button battery ingestions are rarely witnessed. Children might present with vague symptoms like drooling, difficulty swallowing, or even just being generally unwell. These can easily be mistaken for other common illnesses, leading to delays in diagnosis. In one particularly harrowing case, a child presented multiple times with symptoms of a respiratory infection, only for an x-ray to reveal a button battery lodged in the esophagus. By then, the damage was extensive.

When ingestion is suspected, immediate action is crucial. Getting a chest x-ray is the first step, and if necessary, a lateral x-ray can confirm the presence of a button battery by revealing a characteristic double rim or halo sign. Pre-hospital measures can include giving honey or jam, depending on the child’s age, to help mitigate the damage. However, these should never delay getting the child to the hospital.

Once at the hospital, the primary goal is to remove the battery as quickly as possible to prevent further injury. Depending on the location of the battery and available specialists, either ENT surgeons or paediatric surgeons may perform the removal. Post-removal care involves monitoring for complications like perforations or fistulas, which can develop days or even weeks later. In severe cases, these injuries can lead to life-threatening conditions, such as aorto-esophageal fistulas, which require immediate surgical intervention.

In summary, button battery ingestion is a serious and often underappreciated risk. Even in homes where precautions are taken, accidents can happen. The key is quick recognition and action. As parents and caregivers, we need to be vigilant about keeping these small, dangerous objects out of children's reach. And if an accident does occur, immediate medical attention is essential to minimize the risk of serious injury.

Ep 238 - Positive and Negative Predictive Values: Critical Appraisal Nugget

In this St. Emlyn's podcast, Rick Body and Greg Yates, continue our exploration of diagnostic test accuracy, shifting our focus to positive predictive value (PPV) and negative predictive value (NPV). These concepts are vital for anyone preparing for exams or looking to enhance their application of diagnostic tests in clinical practice. While our last podcast discussion centred on sensitivity and specificity, PPV and NPV offer a different, arguably more clinically practical perspective on interpreting test results.

Positive predictive value (PPV) and negative predictive value (NPV) are essential tools for understanding the effectiveness of diagnostic tests. PPV helps us determine the likelihood that a patient with a positive test result actually has the condition, whereas NPV helps us gauge the probability that a patient with a negative test result does not have the disease. These values are crucial for making informed clinical decisions, particularly when considering the prevalence of a condition in the population. Today, we’ll delve into these concepts, their practical applications, and why it's important to consider both PPV and NPV alongside sensitivity and specificity.

Ep 225 - A deep dive into ECMO with Andy Curry

One of the benefits of the use of online platforms for meetings is the ability to record and disseminate talks more widely. This is an edited version of a talk given by Dr Andy Curry, Consultant Cardiothoracic Intensive Care Consultant at University Hospital Southampton, covering the origins of Extra Corporeal Membrane Oxygenation (ECMO) right up to the present day. Throughout the talk, he gives real world experience, coupled with a knowledge of the literature to communicate all you could ever want to know about this fascinating and potentially very exciting therapy.

Ep 221 - Brief Resolved Unexplained Events with Jilly Boden at the PREMIER Conference

The clue to these is very much in the Title – BRUE is a diagnosis in itself. Children often do weird stuff, but they rarely do weird scary stuff.

In this talk, Jilly goes talks through how we can define these events as high and low risk and gives us tools to manage these patients (and their parents)

Along with colleagues, Jilly has written a guideline for BRUE, the full version of which you can find here

Jilly also mentions a flowchart from Peds Cases, which you can find here

 

There is also this superb blog post from Natalie May on the St Emlyn's website which accompanies this podcast, which goes through some really useful cases.

As a Wessex ST7 in Paediatric Emergency Medicine (RCPCH), Jilly Boden currently works in Queen Alexandra Hospital (Portsmouth).  Her specialist interests include acute stabilisation and transfer of the critically ill patient, having spent a year with the 'Southampton & Oxford Retrieval Team' (SORT) and hopes to find a way of combining this with her future PEM career.

Jilly has a passion for education, particularly 'PEM to the non-paediatrician', including international teaching of the tri-service military GPs, and being on the national committee to write a new standardised paramedic paediatric curriculum.

In her free time (you know, apart from the kids and all that) she works as part of the track medical team for the 'British Motorcycle Racing Club', providing pre-hospital care to high velocity polytrauma patients in the 'golden hour' following collisions often exceeding 120mph. 

Ep 220 - Penetrating Injuries with John O’Neil at the PREMIER Conference

This episode of the podcast is a live recording from the PREMIER Conference of John O Neil discussing penetrating injuries with learning points that are useful for clinicians who look after both adult and paediatric patients. 

There are three main mechanisms – violence, impalement and self harm, although the first is by far the most common. 

Penetrating injuries are rare but have significant morbidity and mortality. The key is early and accurate diagnosis, and many can be managed conservatively. The distribution of penetrating injuries across the UK differs widely, with most in the London area, although as seen in the news recently can happen anywhere.

Remember how traumatic it is to be a trauma patient. We put you on a bed, cut off your clothes, stick needles in you and take your family away. Some will also just not engage with you (teenage boys particularly) making assessment difficult. Be kind. Don’t get frustrated.

Physiologically there may be a strong vagal response that can hide some of the signs we’d expect. Also, bear in mind the events prior to the injury – the child may have been running a considerable distance (before and after the incident) raising their lactate (but don’t assume this is the cause). Children tend to ‘fall off a cliff’ – they appear well, but can suddenly decompensate – keep the momentum to definitive management going and do not be falsely reassured.

John mentioned a great friend of St Emlyn’s Vic Brazil and we would heartily endorse you have a look at her work.

Ep 219 - Blast Injuries with Chris Hillman at the PREMIER Conference

Chris brought us his reflections amnd knowledge from some of his extensive experience as a military EM consultant in two wars. Blast injury could be blunt, penetrating, may involve major haemorrhage: you have to expect any injury possible. It’s worldwide and it’s getting more common. 

Blast injury affects every body cavity, but it is the CABC approach that matters, Doing the basics well is still the key. Bleeding points may not be obvious so apply tourniquets wherever stops the bleeding.

Often patients will not arrive in ones or twos but as a whole group affected by an incident, so it is vital we are prepared. The Paediatric Blast Injury Field Manual is a free resource available to download here and is highly recommended.

Chris Hillman is a Consultant in Emergency Medicine and Paediatric Emergency Medicine, working in Southampton. Serving in the Royal Navy since university, he has deployed on Ships, Submarines and with Commando units globally, and with the Army to Afghanistan and Iraq. He is the outgoing Consultant Advisor in Emergency Medicine and Clinical Director Commando Forward Surgical Group. 

 

Ep 218 - Non epileptiform seziures with Steve Warriner at the PREMIER Conference

This is the second in our series of talks recorded live in June 2023 at the PREMIER conference.

Looking after patients with non-epileptiform seizures are a challenging, and common, event in the Emergency Department. 10% of attendances at paediatric neurology clinics are thought to be 'functional' and a lot of these will also present to the ED. These problems can involve a wide range of physical or sensory manifestations, almost all of wide have significant differentials which we cannot miss.

 

A large number of these patients can end up with an incorrect diagnosis, some of this due to confirmation bias by clinicians, but also some with psychogenic non-epileptiform seizures may coexist with organic problems.

 

The history is key and can be helped significantly by watching videos of events. There may be other factors giving a clue to a non-epileptic cause. Sometimes this will only happen in one place, like school, and the history may be inconsistent. Awareness and generalised bilateral movements, with episodes that are different each time all point to a non epileptiform origin. And then there are symptoms just 'not fitting' with our knowledge of dermatomal distribution.

 

There are Red Flags - Events happening during exercise, neurological signs, unpredictability and patterns to the events all point to a more sinister diagnosis

 

Management is incredibly difficult, particularly in trhe ED. Don't suggest an organic diagnosis and leave some ambiguity. There is time to get more information and there are few definitive diagnostic tests. EEGs are notoriously unreliable. Self help groups can help.

 

Steve Warriner has worked as a paediatrician at the QA in Portsmouth for the last 16 years. He trained in various regions in the UK including the Midlands, Yorkshire and the North East of England before working in Somerset for a brief period. He has a particular interest in epilepsy and neurological conditions in children and lead the district epilepsy service in Portsmouth. He teaches on the British Paediatric Neurology Association epilepsy training courses both in the UK and across the world. He was part of the team who designed and implemented the training course (initially in Myanmar) and the method of cascade training has recently been recognised by the World Health Organisation and the course now runs in nearly 30 counties in 3 languages. Steve recently chaired a multidisciplinary working group to update the Advanced Life Support Group guideline for management of prolonged seizures. In his spare time, Steve is a triathlete who qualified for and competed in the World Ironman Championship race in Hawaii in 2022.

Ep 213 - Sensitivity and Specificity (CAN 10)

The latest CAN is one of our brand-new 'revision editions' -- brief podcasts aimed at covering the essentials of critical appraisal for medical students and junior doctors preparing for exams.

With the help of Gregory Yates, an academic doctor based in Manchester, this episode introduces two core concepts: sensitivity and specificity. These are two ways of thinking about the accuracy of a diagnostic test. Knowing the sensitivity and specificity of an investigation will give you a decent idea of how it should be used in the emergency department.

Sensitivity (Sn) describes the chance that a test will be positive if your patient has the condition you're testing for. Some people call it the 'true positive rate' or alternatively the positivity in disease (PID) rate. If you need a hand remembering it, you can always remember that PID is a sensitive issue.

 

Meanwhile, specificity (Sp) considers the chance of a test being negative if the patient doesn't have the condition you're testing for. It's the 'true negative rate' or alternatively the negativity in health (NIH) rate. There are times when we particularly need a test to have a high sensitivity. This is generally when we want to be particularly confident that a test accurately identifies everyone with the relevant condition because we really don't want to miss it. We need a high sensitivity to rule out disease. (Sn-uff it out). At other times, we need to be confident that a patient with a positive test actually has the disease - for example, if the treatment is unpleasant or involves exposing patients to risk. In that case, we want a high specificity to rule in disease. (Sp-in it in).

 

In this CAN, we use D-Dimer as an example of a very sensitive investigation: it’s positive in nearly 100% of cases of venous thromboembolism. Specificity describes the likelihood that the test will be negative if your patient does not have the disease. We use HbA1c as an example of a highly specific investigation: it’s rarely used in the emergency department, but if it’s elevated, we can be almost certain that the patient is diabetic. HbA1c is almost never (<1%) raised in non-diabetics.

The trouble is, many patients with a positive D-Dimer do not have a venous clot, and the majority of diabetics will have a normal HbA1c! No test is perfect, and we discuss how emergency physicians weigh up sensitivity and specificity when choosing which investigations are the best "fit" for clinical decision-making. By the end of this CAN, you will be ready to do the same -- in your exams, and on the shop floor.

 

Ep 212 - February 2023 Monthly Round Up

Our regular monthly round up and chat from the St Emlyn's blog. We talk about the use of artificial intelligence in research and the use of remifentanil instead of neuromuscular blockade in rapid sequence intubation. Plus more about the StEmlynsWILD conference and Simon's new role as Dean of RCEM and how you can get involved. 

Ep 211 - Semi structured interviews (CAN 9)

Long term listeners to the St Emlyn’s podcast may remember our series entitled ‘Critical Appraisal Nuggets’ (CANs). We are absolutely delighted to reinvigorate this project under the leadership of Professor Rick Body, with the episode on semi structured interviews.

In this easily digestible and succinct podcast Rick and Laura Howard go through the pros and cons of setting up semi structured interviews and how these can be used effectively in qualitative research.

In the latest episode, we cover a qualitative research technique: semi-structured interviews. Qualitative research might be out of your comfort zone: we’re generally more comfortable with quantitative measures – numbers and statistics. It’s something they have experience with, having previously published a paper exploring the impact of events that happen at work on the wellbeing of emergency physicians. This was a labour of love for Laura. Laura wrote a powerful blog about it here.

Semi-structured interviews are a great way to get the really rich data we need to understand something in greater depth. They allow us to ask ‘why?’ as well as just ‘what?’, ‘who?’ and ‘when?’. But reading qualitative research papers can be difficult when it takes us out of our comfort zone. In this CAN podcast, Laura and Rick take us through what semi-structured interviews are, why we might use them, how you design and conduct them, and they also have some pearls of wisdom about how to make transcribing them a lot less painful. By the end, we hope that you’ll feel confident with the basics of the technique. And if you want to practice your critical appraisal, why not put their study under the microscope?

Ep 210 - January 2023 Monthly Round Up

Lots of chat about St Emlyn's WILD and just what you can expect if you join us in the Lake District in June, as well as discussion about ECMO in cardiac arrest and just how many of our patients with 'minor head injuries' will actually have ongoing symptoms weeks and even months later.

Ep 209 - November and December 2022 Round Up

A special double edition covering the blog posts from November and December and more. We discuss evidence based medicine with the DoseVF trial, and more from RECOVERY, discussion about 'what is downtime' and how we organise follow up for patients who don't live in our area and what happened at the amazing London Trauma Conference

We also announced some of the plans for StEmlynsWILD. Look out for booking details and more in the coming weeks. 

Ep 208 - What is Wellbeing with Liz Crowe

Wellbeing is very complex, as it is an individual construct that is strongly aligned and interpreted through a lens of personal values, philosophy, culture, faith, and goals for life. Most importantly, wellbeing is dynamic rather than homeostatic and a subjective state determined by the individual.

Yet we use the term wellbeing to describe a wide variety of different things (often in terms of being the opposite of burnout which it most certainly isn't). 

In this second episode of our series Liz Crowe discusses in detail what the literature says about wellbeing and how we may be able to use this going forward.

Please do like and subscribe. Thanks for listening.

Ep 207 - Burnout with Liz Crowe

Burnout is a term that seems to be used a lot these days, but what does it really mean? In this episode Dr Liz Crowe explains all, and will almost certainly change the way you view burnout. 

Liz, who be well known to St Emyn's audiences, has just completed her PhD on "Understanding the risk and protective factors for burnout and wellbeing of staff working in the Paediatric Intensive Care Unit: PICU staff wellbeing" and has an unrivalled real world and evidence based experience of what these terms really mean.

In this first in a special series Liz goes into depth describing not only what burnout is, but how it can be measured (and the limitations of this) and most importantly how this is a system issue and not a diagnosis.

In the next episode we will discuss another commonly used term 'wellbeing'.

We think this series is incredibly important and hope you will help us share it far and wide. You can read the accompanying blogpost here.
