Sie wissen ja vermutlich, dass ich absoluter Anhänger der Rubrik “Clinical Problem Solving” im New England Journal of Medicine bin. Didaktisch hervorragend aufbereitet, werden
auch schwierige und komplexe Fälle sehr praktisch anwendbar beschrieben. So auch hier bei einem Patienten mit therapierter Haarzellleukämie, der sich wegen Fieber, vesikulärem Ausschlag am Rücken und noch anderer Beschwerden vorstellt. Schrittweise führen die Autoren durch die Abklärung und dann auch Therapieversuche. Ich für mich habe wieder ein schon in die Tiefen des Gehirns verdrängtes Syndrom wiederentdeckt: Das “SWEET SYNDROM“. Auch differentialdiagnostisch gelegentlich in der Notfallversorgung zu erwägen.
Sie werden sich fragen, warum ich einen derartigen Fall in einem Blog zur Notfallmedizin vorstelle und bewerbe: Nun, wir sind immer wieder mit derartigen Fällen konfrontiert. Und auch wenn diese zur weiteren Abklärung dem Fachspezialisten zugewiesen werden, kann man aus derartigen Fällen viel über den Verlauf einer Erkrankung lernen. Außerdem zeigt es in brillianter Art und Weise auf, wie man über die Zeit schrittweise seine Arbeitshypothesen entwickeln kann, die Diagnostik anstossen und dann auch seine Arbeitshypothesen verwerfen kann. Aber, der Fall ist nicht nur didaktisch exzellent, er zeigt in brillianter Weise wie spannend Medizin sein kann. Voraussetzung ist natürlich, dass man Ressourcen hat … und das ist bei uns gelegentlich durch die Arbeitsbelastung, wie auch aktuell wieder bei uns am WE, häufig nicht so gegeben ist.

This Edition’s R&R Hall of Famer
Frat JP et al. High-flow oxygen through nasal cannula in acute hypoxemic respiratory failure. NEJM 2015; 372(23):2185-96. PMID 25981908
Two different takes on a potential game changer in how we initially manage hypoxic respiratory failure from our contributors.
- “HFNC for acute hypoxemic respiratory failure improves mortality and patient comfort over BiPAP and standard oxygen therapy” — This is the headline you are going to see BUT is not the entire truth. Here are a few of the caveats….
- There were significant exclusion criteria so these patients only had hypoxic respiratory failure (single organ failure).
- Included a significant proportion of unilateral lung disease (not just ARDS patients) whose mortality is historically a lot lower.
- Significant (and unreported) cross-over rates between NIV and HFNC groups, and it’s unclear why tidal volume targets were 7-10 cc/kg ideal body weight.Bottom line: HFNC should not replace or delay definitive management (an ET tube) in patients with acute hypoxemic respiratory failure.
- We know in hypercarbic respiratory failure (i.e. COPD & CHF Exacerbations), NIPPV decreases mortality and intubation rate. In this study in patients with hypoxemic respiratory failure without hypercarbia (majority of population with pneumonia), HFNC appears to be superior to both NIPPV & O2 with Face Mask and should be strongly considered as first line treatment.

The Best of the Rest
Emergency MedicineZonfrillo MR et al. Emergency Department Visits and Head Computed Tomography Utilization for Concussion Patients From 2006 to 2011.Acad Emerg Med 2015. PMID: 26111921
- Increasing awareness exists on concussions/mild traumatic brain injury (TBIs) and this correlates with an increase in ED presentations for concussions between 2006-2011. Similarly, there’s been an emphasis on use of clinical decision aids for mild head trauma during this period. Despite this, a significantly limited database review found there was an 11.1% absolute increase in the rate of head CT for concussion patients over this period despite apparent decreased injury severity, measured by ISS. Concussion/mild TBI certainly deserves increasing awareness but inappropriate imaging doesn’t behoove anyone and appears to be a growing problem in this realm.

Emergency MedicineBeam DM et al. Immediate Discharge and Home Treatment With Rivaroxaban of Low-risk Venous Thromboembolism Diagnosed in Two U.S. Emergency Departments: A One-year Preplanned Analysis. Acad Emerg Med 2015. PMID: 26113241
- Venous thromboembolism (PE and DVT) are almost always managed in the US with an inpatient stay while anticoagulation is begun. However, there are likely low risk groups that can be discharged from the ED without a hospital stay. This study prospectively looks at 106 patients with either DVT or PE who were identified as low risk based on the Hestia criteria. All of the patients were started on rivaroxaban (a Factor Xa inhibitor) and none had VTE recurrence (while on anticoagulation), major bleeding events or death due to VTE. This study further supports outpatient management for low risk VTE but a randomized controlled trial is needed (keep your eye out for the MERCURY-PE study)

Research and critical appraisalHorowitz BZ, et al. Droperidol–behind the black box warning. Acad Emerg Med. 2002; 9(6):615-8. PMID: 12045077
- An older, but outstanding blow by blow look at the cases which led to the FDA black box warning on droperidol in the U.S. The authors examine each case submitted and find some curiosities:-55 of the 93 deaths reported were submitted on the same day
- The overwhelming majority of adverse event cases were reported with significantly higher doses of the drug than that routinely used in the EDThe authors also nicely summarize what we knew about alternative agents at the time of the editorial (2002), and is well worth reading for all those wondering why such a useful drug has been eliminated from the formulary at many hospitals. HT to Sean Nordt and Rob Orman for their discussion of the issue and editorial on ERCast.

NeurologyAVERT Trial Collaboration group. Efficacy and safety of very early mobilisation within 24 h of stroke onset (AVERT): a randomised controlled trial. Lancet 2015. PMID: 25892679.
- In a massive and well-conducted RCT of 2104 patients with stroke, they randomized half of them to very early mobilization (median of 18.5 hours to first mobilization vs 22.4 hours), and more intensive mobilization (31 minutes per day vs. 10 minutes per day) for longer (202 total minutes vs 70 total minutes). Depending on how you prefer to analyze the results, there was either no difference (on the “assumption-free ordinal analysis” that uses the whole Rankin scale) or evidence of harm in the adjusted analysis that dichotomized the outcome scale.This surprised me–I had assumed that we were nowhere near giving “too much” exercise to anybody in any ICU. Apparently there may be a downward limb of the exercise/benefit curve. Clearly we need some more RCTs, not just willy-nilly assertions that more exercise is better. BUT, we should also remember just how much more exercise the usual care in this trial got, compared to the amount of exercise my typical medical ICU patients get. I do NOT think this paper provides an excuse to stop mobilizing patients who are currently getting next to nothing.

Critical CareHilton AK, Bellomo R. A critique of fluid bolus resuscitation in severe sepsis. Crit Care 2012; 16(1): 302. PMID: 22277834
- The concept of the fluid bolus in resuscitation of the critically ill, especially in septic shock, is almost sacrosanct. Hilton and Bellomo tear down the facade that underpins this dogma. Read this and you will be left wondering what to believe… Is it time for a FEAST trial in adults in the developed world? In the meantime, continue to take the middle road in septic shock – judicious use of resuscitation fluids (e.g. 2-3 L at most in most adult patients) and early use of noradrenaline.

Salminen P et al. Antibiotic Therapy vs Appendectomy for Treatment of Uncomplicated Acute Appendicitis The APPAC Randomized Clinical Trial. JAMA 2015; 313(23): 2340-2348. PMID: 26080338
- Can we treat acute, uncomplicated appendicitis with antibiotics alone? According to this RCT (can’t blind this one) the answer is yes. Antibiotics alone had a 72.7% success rate measured by the absence of needed appendectomy at 1 year. However, the failure rate (27.3%) exceeded their prespecified non-inferiority criteria of 24%. Appendectomy was successful in 99.6% of patients. Patients who underwent appy were much more likely to have complications (2.8% vs. 20.5%) but the vast majority of the appys were done by an open technique. Although we hoped this would answer the question, it has only added more. Antibiotics alone may be a reasonable 1st approach but we should expect a high failure rate if this strategy is pursued.
- An antibiotics-first strategy for acute appendicitis had a failure rate of about 27% at one year – not bad, but longer-term follow-up for durability of cure is needed to endorse such a strategy.

The post Research and Reviews in the Fastlane 090 appeared first on LITFL: Life in the Fast Lane Medical Blog.
Today, Thursday 9th of July 2015, I have the opportunity to speak to Australia’s medical students at The AMSA National Convention Melbourne 2015 about ‘Hacking Medical Education’. This post contains the resources for the talk.
The talk is dedicated to the memory of Dr John Hinds, who tragically died last weekend. The simplest advice one can give to any medical student is “Be like that guy – Dr John Hinds“. Ride on, John.
What do I mean by Hacking Medical Education?
Hacking means many things – all of which apply to this talk to some extent (especially the latter):
- “gaining unauthorised access to data in a system…”
- “cut with rough or heavy blows”
- “to modify or write… in a skillful or clever way”
By medical education, I don’t only mean getting through medical school, but also (and more importantly) our lifelong path of learning in medicine.
HACK #1 Learn from Osler!
HACK #2 Discover the hidden curriculum!
- There are three at least three ‘hidden curricula':
- the unintended things you learn from a course
- the things you really need to know to pass the course (may be different from what is stated)
- the ‘internal’ curriculum you need to develop to be the doctor you want to be and look after the patients in front of you
- The Necessary Evil of Examinations (they are ‘rocks of offence’, however ‘assessment drives learning’)
- FCICM Exam Preparation (preparation for an exam must be exam specific, this page outlines useful approaches for the Fellowship of the College of Intensive Care Medicine; however many of the suggestions and techniques are generalisable)
- We don’t need no FOAM Curriculum (we need to develop our own ‘internal curricula’ that supplement those set for use by Universities and Colleges – FOAM resources can help here… see below!)
HACK #3 Apply cognitive science!
- Effective learning techniques are not widely taught, are not widely known and are not widely performed
- Cognitive science highlights some promising techniques, although definitive evidence of their effectiveness in the medical setting is generally lacking
- We construct knowledge, it isn’t transferred
- Use these techniques:
- retrieval practice and take advantage of the ‘test effect’ (putting things into our brains isn’t that hard, being able to retrieve it at the right time can be – practice retrieval, ideally in the context in which you want to be able remember something)
- spaced repetition (try to practice retrieval at just the time you are about to forget something to promote durable learning)
- elaboration (channel your inner 3 year-old: ask ‘why?’ and explain things to yourself and others)
- generation (test your knowledge of a topic before learning about it – ask yourself questions and try to predict what will be said before reading a section of a book or article)
- reflection (reflect on your experience – combines retrieval practice and elaboration and is a way of giving feedback to yourself)
- calibration (get objective feedback so you are not deluding yourself as a learning)
- interleaved practice (mix up problem types and topics during practice to prepare you for the real world)
- Learning by Spaced Repetition (I used software called Anki to help me remember key facts for exams)
- Effective Learning Techniques Revealed (brief summary of the techniques given the thumbs by Dunlosky et al, 2013)
- Dunlosky J, et al. Improving Students’ Learning With Effective Learning Techniques: Promising Directions From Cognitive and Educational Psychology. Psychological Science in the Public Interest, 2013; 14 (1): 4 DOI:10.1177/1529100612453266 [Free Full Text] (great review of the science of effective learning techniques)
- Brown PC, Roedinger HL, McDaniel MA. Make It Stick. Harvard University Press, 14 Apr 2014 [Google Books] (excellent popularisation of the ‘new learning science’)
- Education Theory for the #MedEd Clinician (key insights from Jonathan Sherbino, a master clinician educator)
HACK #4 Simulate!
- good patient outcomes need more than individual competence, they need collective competence – team-based simulations can help achieve this
- Hadfield, C. An Astronaut’s Guide to Life on Earth. Random House of Canada, 29 Oct 2013 [Google Books]
- In situ simulation (simulation in the workplace, with real teams in the environment in which we work, rocks!)
- Simulation-based learning helps develop essential non-technical skills: Crisis Resource Managment, Communication in a crisis and Speaking up
HACK #5 Join the FOAM Party!
- Why FOAM? Facts, Fallacies and Foibles (my talk providing an overview of FOAM)
- Nickson CP, Cadogan MD. Free Open Access Medical education (FOAM) for the emergency physician. Emerg Med Australas. 2014;26:(1)76-83. [pubmed] [Free Full Text]
- FOAM (Free Open-Access Meducation homepage)
- Is FOAM at fault? (FOAM is an adjunct, nothing replaces the bedside mentor!)
- SMACC (the Social Media and Critical Care conference)
- RAGE podcast (the Resuscitationist’s Awesome Guide to Everything)
- INTENSIVE (the Alfred ICU’s education and knowledge translation blog)
HACK #6 Be a Critical Thinker!
HACK #7 Work Smarter and Get Things Done!
- Learning medicine is hard work, learn to love it
- Strive for mastery, not success
- “It is up to us to save the world” – Peter Safar
