Review – Auckland HEMS app

My friends over at Auckland HEMS have just released an app for both iOS and Android (see link at “test pilots wanted - HEMS app goes live“). I was lucky enough to score a pre-release download and play with it over the past week. It’s now been released live and available to all for feedback.

I’ve been a bit of a fan of the Auckland HEMS site – along with a few other retrieval services, they’ve made a commitment to having a web-presence (good for promotion, recruitment and also promoting information sharing via feedback). Their sim resource section is one I am watching closely, as there is great scope to share sim scenarios using the in-built function of the online community functionality of the iSimulate package

Other services, notably the collective UK HEMS, Sydney HEMS, RFDS have lead the way in sharing some of their resources in open-access format, to help others to learn and develop own procedures, as below :

Putting procedures and information up on the web is one thing…but the ultimate functionality for a retrievalist would be to have all of this information available even without immediate web access. Given the space constraints of a flight suit, and the ubiquity (and of course practicality) of a smartphone, it makes sense to develop retrieval apps that can be used on the primary communication device (iOS or Android phone).

Having a smartphone allows access to not just phone calls, but messaging, web access (if in range), ability to view documents, access apps etc. Smart app developers may also take advanatage of in-built functions such as torch/vibrate/sounds to enable visual, haptic & audio prompts. Inter-app integration for access to weather and map/GPS functions is achieveable. And the new iPhone reportedly has a barometer…opening the possibility of a retrieval app that helps flight planning and working out O2 requirements.

It’s probably worth reflecting on what the ideal retrieval app would allow a user to do. My opinion is that the ultimate app would allow

  • cross-platform functionality (iOS, Android) and usable on both phone and tablet screens
  • ease of use in sunlight and at night, with clear easy to navigate buttons
  • large buttons/tab/checkboxes, so that can be used even when wearing gloves
  • capability to record day-to-day activities within a service, eg: daily kit checks, viewing of approved rosters, navigation to useful contact numbers. Daily checklists should be exportable for audit purposes.
  • ability to record case details including case times (from activation through arrival/depart scene, dropoff at destination and return-to0base for audit purposes), record mode of transport, locations, patient demographics and coding of disease, with ability to easily export such data to databases such as Air Maestro or common office-based spreadsheets (Excel, Numbers), thus avoiding the duplication of data entry across multiple sources (ie case notes-apps-database). Naturally such recording should be password protected and HIPAA compliant.
  • ability to record scene photos or videos, protected as above, to communicate scene situation (useful particularly in a major incident) as well as to facilitate audit and training
  • integration with maps functionality, with ability to record GPS points and drop pins on location
  • access to marine & weather info
  • use of barometer function on newer smartphones for use in-flight
  • access to service-based standard operating procedures (SOPs), preferably with documents in an interactive iBook-type format to optimise viewability, rather than the difficulties of navigating PDFs on a small smartphone screen
  • access to service-approved short videos demonstrating procedures for training
  • access to relevant FOAMed links inc available podcasts/vodcasts (on the outward leg, especially via fixed wing in rural Australia, it would be hard to go wrong with the audio & video content from intensivecarenetwork.com, smacc.net.au, emcrit.org, prehopsitalmed.com etc)
  • ability to log any issues eg: equipment failure or hot debrief for the team
  • ability to record all data and export as appropriate to both service audit and governance needs, as well as record cases/procedures for clinicians requiring for logbook purposes
  • app available for moderate fee, and sharing of content between services where appropriate ie : where benefits of open-access information offer advantages (the obvious example being developing standardisation of SOPs, equipment between a retrieval service and the rural hospitals it services eg: infusion regimens etc)

So far no such app exists…but there have been some rapid developments in this area in recent times. The Auckland HEMS app is interesting, in that the authors (Robert Gooch, Chris Denny under IT tutelage of Scott Orman) have used the iBuildapp web-based service to create the content, thus saving a huge investment of $$$ on an app developer. As they say “if you can create a powerpoint presentation, you can create an app”. What I like is the commitment to evolve the app and update in real time.

The app starts with a simple splashscreen, then once loaded moves to a very easy to navigate interface, reminiscent of the UKHEMS SOP database web-interface.

IMG_4873
Auckland HEMS app is loading…

The initial screen has large, friendly coloured buttons that are easy to select even when wearing gloves, allowing access to each of :

  • emergency checklists
  • normal operations checklists
  • shift duties
  • major incident prompts (METHANE, NATO phonetic alphabet etc)
  • resources (including web links to FOAMed)
  • calendar
  • SOPs (standard operating procedures)
  • comms
IMG_4874
Easy navigation to selected content

Drilling down, the content is easily displayed and large – this is a plus, as small text is both hard to read and hard to select (especially in gloves). However I was disappointed to see that checklists did not actually allow ‘checking’. This is a shame – for a daily kit check, ability to select actions completed and then archive the actions (eg: CSV export via email) would be useful.

IMG_4876
Ventilated patient – accidental disconnect checklist

For a crisis checklist, the ability to check items or even build in audio-haptic-visual alerts using smartphone alarm-vibrate-torch functions can be very useful in a crisis, especially when time critical. The obvious example is that of RSI – and for a masterclass in how a checklist can be made part of workflow, see the excellent iRSI app, reviewed elsewhere.

IMG_4824

The ‘hot debrief’ function accessed from the bottom navigation file was useful – easy to access wherever you are in the app, this allows quick notation of mission details such as nature of mission, team members, timings and also commentary on any issues with kit, at the hospital or in transport. Again, ability to capture this data and export it to a spreadsheet for audit or training purposes would be invaluable.

I was pleased to see the inclusion of some FOAMed material, including Scott’s cric-con concept for emergency surgical airway. I couldn’t find mention of the Vortex approach, but as time goes on I think this and other resources will be incorporated both into the app and into common practice. Links to relevant sites are included…

Integration of marine and weather bulletins was a nice touch…

…along with calendar and contact info for operational purposes

Ultimately it is hard to demonstrate all functions with screenshots. My advice – get in quick, download the app and give your feedback. It is available from http://aucklandhems.com/2014/09/21/test-pilots-wanted-auckland-hems-app-goes-live/

I am fully confident of rapid improvements with subsequent iterations. To my mind, the scope for making an open-access app with broad-brush functionality according to the list above is achievable. The question, of course, is how much content should remain in-house (mindful of the considerable investment in time, money and intellectual copyright of content) and how much can usefully be shared.

Whether making one’s SOPs and resources open access is worth it remains unanswered. For blokes like me, trying to do best for rural patients, there are clear advantages in keeping up-to-date with current practice and especially in aiming to use the same kit and infusion regimens as the retrieval service. I appreciate however that there may be concerns in making one’s protocols available for all to share.

For the present, I am grateful for the availability of online resources such as those from Emergency Medical Retrieval Scotland, SydneyHEMS and UKHEMS

FOAMed – a Primer for Physicians

So this week I am giving a talk to a bunch of physicians at the Internal Medicine Society of Australia & New Zealand. In true FOAMed spirit, I’m making the talk available online prior to the session (as a nod to the concept of a ‘flipped classroom’) and putting up some useful links for those who decide to explore the FOAMed world a little closer.

Big thanks to Chris Nickson for the inspiration of using Star Wars stormtroopers as a metaphor for ‘taking the world by storm’…and of course to Joe Lex for both the oft-quoted phrase “if you want to know how we practiced medicine…” as well as introducing me to the terms of pedagogy, andragogy and heutagogy.

They say that an audience will only take away THREE things from any talk. The concepts I wanted to get across were :

  • half of what we learn is wrong; FOAMed is a tool to help narrow the knowledge translation gap and keep up-to-date
  • we live in an age of information overload, likened to ‘drinking from a firehose’. Social Media tools allow filters to help drill down to the information that is relevant to your needs
  • using the tools of FOAMed and social media, we can make a commitment to lifelong learning much easier. Moreover, with such accelerated learning comes the potential for metacognition – specifically to understand HOW we learn and make decisions as clinicians. This is important as our diagnostic acumen is subject to bias and may fool us, regardless of our knowledge base.

So, here’s the talk as a narrated slideshow hosted on vimeo :

http://vimeo.com/105729442

The slides can be downloaded by clicking HERE as a PDF file and HERE as a powerpoint inc embedded video

 

The introductory video (FOAMed – taking the world by storm) is below :

http://vimeo.com/105093904

What is FOAMed and why should I use it?

I like to think of FOAMed as a global sharing of information. We are all involved in clinical educators  we get up at journal clubs, grand rounds or conferences and deliver talks. But the reach of those talks is confined to those who attend…unless you take the bold step of creating online content – basically, putting up your ideas, talks, slides etc online in a form where ANYONE can access them. This might be in the form of a blog (reading commentary or analysis), a podcast (eg : listening to a discussion on a contentious topic) or a video (watching how to perform a procedure).

Good FOAMed sites collate information, curate it and disseminate it – with information made available for free (although attribution is expected).

It is hard to go beyond the summary of FOAMed origins and uses from the lifeinthefastlane.com crew

Chris Nickson talks about “Why FOAMed – facts fallacies and foibles”

Andy Neill’s pecha kucha talk is here “Effective Use of Social Media to Keep Up-to-Date

Richard Body talks on why FOAMed is essential for emergency clinicians (from #CEMExeter14 conference)

https://www.youtube.com/watch?v=WyAfkbcISDQ

David Marcus has a great set of slides here : FOAMed primer and other talks at EM IM blog

Some great examples of collated & curated FOAMed sites include :

gmep.org

lifeinthefastlane.com

emcrit.org

prehospitalmed.com

resus.me

scancrit.org

stemlynsblog.org

dontforgetthebubbles.com

ruraldoctors.net

BroomeDocs.com & KIDocs.org

and so on…

There are MANY MANY more – mostly emergency and critical care, but increasingly other specialties are coming on line – urologists (eg uroJC twitter journal club), general practitioners (FOAM4GP.com) etc.

The maxim is for :

content creation – with collation, curation … and communication

The list of available FOAMed resources is growing exponentially (over 400 blogs for EM/CC alone).

The sites above reflects MY bias and learning needs – it may not reflect yours!

So – dive on in and explore the FOAMed world (Google FOAMed)…and if you cannot find any relevant content on an area in which you have expertise or passion, then GET BUSY and CREATE YOUR OWN! The more quality content that is out there, the better for everyone…

 

The best medical conference – ever!

For an example of how an excellent medical conference should be run, it’s hard to top smacc. Cadogan commented that whilst FOAMed was conceived in a Dublin bar in 2012, FOAMed was conceived at smacc2013 in Sydney. A year later smaccGOLD built on that success, with many different ‘tribes’ involved in critical care and emergency medicine coming together to share stories and learn from each other. Next year we are off to Chicago for smaccUS…check it out & register at smacc.net.au

There is also an iTunes feed for downloadable podcasts - https://itunes.apple.com/au/podcast/smacc/id648203376?mt=2

Of course the collated videos of smacc talks are available on Vimeo via vimeo.com/smacc

Here’s some feedback on smacc from assorted bloggers

“Lessons learned from smacc – bye bye dogma, – hello best practice”

“You’ve gotta have love”

“Social media & critical care”

“smaccGOLD – it hurts”

“Where do you start with something like smacc?”

 

How to use tools of Social Media to help filter and signpost FOAMed

Social media (SoMe) is useful to disseminate and discuss clinical topics. By now you will be aware that there is a vast repository of useful educational resources “out there” on the net – blogs, podcast, videos etc. But how to filter them?

The easiest thing to do is just to read blogs on topics you are interested in or authored by people who you feel have something to offer. One of the nice things about the FOAMed community is that people share good content willingly and will signpost links to interesting content. Good sites collate quality FOAMed material, curate it and disseminate it. They may have a ‘search’ function on the site…failing that, there is always GoogleFOAM.com to search for good stuff.

Screen Shot 2014-09-16 at 11.37.05 am

RSS feeds are ideal – if you see this symbol on a website, click it to ensure that new content is delivered to your email, RSS aggregator or iTunes download queue. This makes it much easier to target FOAMed content that you are interested in – rather than have to trawl through blogs looking for updates, new content is streamed to you. By only clicking on feeds that are of interest to you, one can filter the FOAMed content, to a degree.

rss

 

I am a big fan of using RSS aggregators to collate input from twitter, blogs, google+ etc into an app – I use one called Feedly, which displays my content in a magazine style format

feedly_os_x_icon__ios_7_style__by_johnlongview-d6j9bpj

Twitter. Really?

I was a sceptic initially, but now find that twitter is a great way to keep in touch, ask questions of colleagues, discuss concepts and also signpost relevant journal articles or FOAMed resources.

Twitter is essentially a microblogging platform – once you’ve registered, set up a user ID and a brief description of self/interests, then you are free to either follow like-minded people or start opening up your own conversations. Tweets are limited to 140 characters, so it is very difficult to have a nuanced conversation, Hashtags are common for conferences eg #IMSANZ14 and can also be used to collate information eg : #FOAMed #resus would delineate tweets with these items as search terms.

Attachment-1

The Twitter app is free for download on mobile and PC/OS platforms. Afficiandos may decide to use an app like TweetDeck or TweetBot to allow collation of different content and even schedule tweets (I was involved in an on stage debate at #smaccGOLD on the use of checklists in airway management, and managed to wow the audience by talking and having simultaneous twitter feed broadcast to the audience both in the hall and worldwide, to broaden the reach of my delivery)

Learn how to get started with Twitter from these excellent videos from Rob Rogers and colleagues at theteachingcourse.com - expect more from them

Life Long Learning & Metacognition

More than anything else, FOAMed makes one think about HOW we learn in medicine. Osler nailed this “medicine is a science of uncertainty and an art of probability”. We like to think that we are astute diagnosticians – but we are constrained by our inherent cognitive bias.

Understanding HOW we make decisions is particularly important in critical care medicine – making decisions based on limited information, under pressure.

I recommend :

Simon Carley talks on ‘Guess or Gestalt’ regarding decision-making in EM (from #CEMExeter14 conference)

https://www.youtube.com/watch?v=VQBbXIBBQp4

Chris Nickson on why ‘All Doctors are Jackasses’ (from #smacc2013 conference)

https://vimeo.com/75271893

Joe Lex on why FOAMed is essential to medical education (includes discussion of pedagogy, andragogy and heutagogy)

as well as Lex on ‘from Hippcrates to Osler to FOAM’

…and Chris Edwards’ excellent talk on ‘May the FOAMed Be With You’

There are a few more videos on decision-making & education here :

Damian Roland on ‘Evaluating Education’

Victoria Brazil on ‘Evidence based education’

Cliff Reid on ‘Resuscitation Dogmalysis’

Simon Carley (again) on ‘Do Risk Factors Factor?’

…and yet again, Carley delivers ‘Wrestling with Risk’

…and again on ‘educational Leadership & Subversion’

 

Where to from here?

If you are inspired to create some GOOD medical education content and host as FOAMed, we’d love to hear from you

This post on blogging and blog basics is useful

 

Dive on in – the FOAMed is lovely!

 

ATACC Manual – Quality FOAMed

For those of you have been reading KIDocs over the past year or so will know that I am a harsh critic of the ATLS course (EMST in Australia). Not because I think it’s pants – it’s not. It does what it says on the tin, namely it teaches a basic approach to trauma management for the single responder in a community hospital. The A-B-C-D-E approach is easily taught and easy to recall under times of stress. I have no doubt that the ATLS course has done a world of good in bringing structure to trauma care worldwide.

I’ve been teaching on ATLS-EMST since 2006 and a course Director here in Australia for the past few years. In recent times I’ve seen how quickly FOAMed can narrow the ‘knowledge translation’ gap from concept to practice – and become increasingly frustrated that the ATLS-EMST manual doesn’t really address nuances of modern trauma care.

It should be borne in mind that the ATLS-EMST course is considered mandatory for credentialling in many hospitals. Like many other courses (APLS, ELS, ALSO, ALS) I think this is fine when setting a minimum standard. However it frustrates me that experienced clinicians are expected to repeat these ‘alphabet’ courses every few years.

Don’t get me wrong – I am not saying that experienced clinicians don’t need regular updates and ‘benchmarking’ – but it would be good if the content of the course built upon the basics, not just repeated the entry-level content. I have heard that post-Fellowship emergency physicians in the UK have been required to complete an ATLS course as part of revalidation – when the skills that they apply in their day-to-day job far outstrip those taught on ATLS.

And of course, successful trauma management isn;t just about knowledge and procedural skill. It requires an understanding of how a trauma team functions. We’ve all seen dysfunctional trauma teams, despite the individual excellence of the clinicians, dysfunction arises because of a complex interplay including human factors.

Last year the Australians kicked off the Emergency Trauma Management course (ETMcourse), which is aimed not to replace ATLS-EMST, but to offer content that includes cutting edge FOAMed good ness as well as apply principles of teamwork (clearly human factors are important in how a trauma team functions – or fails). You can read a review of the ETMcourse here.

Other courses such as the anaesthetists EMAC and the retrievalists STAR courses also explore some of these aspects, as well as more challenging scenarios – details on available courses here.

Introducing the Anaesthesia, Trauma & Critical Care Course (ATACC)

But there is another course – the ATACC course. I’d heard about this via doctors.net.uk and been in touch with the course organisers with a view to trying to get a course ‘down under’….which might be difficult! ATACC has an excellent reputation in the trauma world, for teaching real life scenarios in multi-disciplinary team. I am busting to attend one of these courses if I can get back to the UK

The ATACC Faculty include not just clinicians, but also luminaries of extrication such as Ian Dunbar (of the Holmatro extrication techniques app and book fame). Similarly the course is open to all – doctors, nurses, paramedics, physicians assistants, operating department practitioners – anyone who is involved in trauma. A far cry from the College of Surgeon’s ‘Advanced Trauma Life Support Course – for doctors’.

Screen Shot 2014-09-11 at 5.13.36 pm

 

ATACC Faculty includes Ian Dunbar (@Dunbarian) author of the excellent extrication manual sponsored by Holmatro – also available as a truly interactive app/iBook – worth every penny for anyone interested in prehospital care

 

ATACC Manual Available as FOAMed – PDF or iBook versions

 

So mega-kudos to the ATACC mob for launching their course manual as FOAMed – I’ve just got my hands on a copy and I can attest that it is thoroughly excellent.

Screen Shot 2014-09-11 at 5.01.13 pm

The PDF copy is available here

http://www.atacc.co.uk/e-learning/

or in iBook format via iTunes here

https://itunes.apple.com/us/book/anaesthesia-trauma-critical/id917866158?ls=1&mt=13

I cannot begin to tell you how good this manual is – it covers modern trauma management, is interactive and authoritative. It covers the usual trauma stuff, but is packed with some extra nuggets – I am a big fan of the MARCH approach and was pleased to see this included, along with some other adjuncts to haemorrhage control including haemostatic agents, clamps and the like. Up to date controversies (#dogmalysis) on topics such as cervical spine immobilisation are also covered – and my understanding is that content will be regularly updated.

Screen Shot 2014-09-11 at 5.17.56 pm
The ITclamp for haemostasis
The MARCH approach to roadside trauma
The MARCH approach to roadside trauma

One of the strengths of the manual is that it covers trauma from the roadside, through retrieval, the ED and to ICU. It’s trauma run by traumatologists (did I just say that? Bah!) – not by surgeons. As such I recommend it to anyone involved in trauma care – prehospital clinicians & retrievalists, rural docs, EM types, anaesthetists, doctors, nurses, paramedics…

Awesome
Everything is Awesome When You Are Part of A (Trauma) Team

That the authors have made it freely available as FOAMed is truly humbling! I remember that it was only a couple of years ago that ATLS made their course manual available for non-attendees…and they still charge a packet for the hardcopy. There is an ATLS app – but the less said about that, the better.

The ATACC manual is true FOAMed – quality medical education, up-to-date and freely available because the ATACC mob believe in what they do.

Kudos to you. Seriously.

Loving the section on cervical collars - mentions the Brisbane protocol, decision-making rules, clearance in ICU etc

I’ll let you know if I ever get to an ATACC course in the UK and review it online. From what I’ve heard and seen of the manual, the three day intensive course must be orders of magnitude of awesomeness!

Meanwhile, I will leave you with this thought on the 9th edition of ATLS-EMST (attribution unknown, apologies)

...seriously - does EVERY trauma patient need a rectal exam? ATLS dogma still says YES (except on courses I direct)

IMSANZ 2014 – ‘FOAMed Taking Life Long Learning by Storm’

I have been asked to speak at the Internal Medicine Society of Australia & NZ annual scientific conference, which will be  held in Adelaide this September.

The idea is to introduce physicians to the concept of #FOAMed. I reckon this could be a tough gig….there are only a few physicians active on SoMe in Aus/NZ and I am not sure how well the anarchic, free-form and rapidly moving concept of #FOAMed will be embraced by them.

Whilst emergency and critical care physicians have been the main early adopters of FOAMed, I reckon that physicians lie somewhere towards the right of the ‘innovation adoption lifecycle model’.

Screen Shot 2014-09-03 at 8.45.49 pm

So my cunning plan is to try and entice as many of the audience in, by playing a short video during the one hour lunch break before the scheduled afternoon session.

I am in a concurrent, going up against local cardiologist Julian Vaule talking on NOACs (“novel oral anti-coagulants”) – or, as I prefer to call them “evil Big Pharma meds that aren’t all they are supposed to be and unlike rat poison cannot be reversed“.

Now I dont know about you guys, but I have sat through a load of lectures on NOACs…but I don’t reckon I ever sat through a lecture on tools for lifelong learning, on metacognition, on use of Social Media to filter educational content for self-development.

The video borrows from the meme of ‘taking life ling learning’ by storm(trooper) – a concept I first saw in a FOAMed lecture from Chris Nickson of LITFL fame, then taken up by others such as Andy Neill from emergencymedicineireland.

The video allows the inclusion of stormtroopers twerking and shufflin’  - what’s not to like? It struck me that these talks plus the video could be used by others when preparing an audience for FOAMed…(since originally posting, was contacted by Simon Carley of StEmlyns.org and asked if could use the video to introduce FOAMed at the 2014 College of Emergency Medicine conference in Exeter, UK this week. Nice to share)

Screen Shot 2014-09-10 at 9.01.13 am

I’ll bung up a slideshow of the IMSANZ on the day it is to be delivered – 19th Sept – as an example of a ‘flipped classroom’. Wish me luck! Gonna be a tough audience….

Resus Room Feng Shui

It’s been a pleasure to present at the biannual EMSA2014 (Emergency Medicine South Australia 2014) in Adelaide, South Australia.

Like smaccGOLD (social media & critical care conference, Gold Coast 2014), the audience was an nice mix of clinicians – grizzled old rural doctors, hardcore emergency physicians, vastly experienced emergency nurses and paramedics…as well as a nice smattering of students.

As always, I suffer from a degree of ‘imposter syndrome’ – what can a rural doctor possibly have to say of interest to this sort of audience?

Spot the Imposter
Spot the Imposter

Unlike smaccGOLD, many of the audience were naive to the concept of #FOAMed (free open access medical education) – so I opted to tell a personal story of how my practice as a rural clinician has changed in the past 2 years, shaped by the mentors in the photo above

“as a rural clinician, FOAMed means there is no longer an excuse for my lack of knowledge to be the weak link in patient care”

In order to close the loop, I’ve made a commitment to put my slides and relative links up on the blog for new FOAMed acolytes to explore.

This whole talk is of course based around the concept of managing oneself, the team, the environment as well as the patient – a concept taken from Cliff Reid’s excellent ‘Making Things Happen’ talk from smacc2013 in Sydney. Worth watching this talk as well as many of the other talks from the smacc conferences past, present…and future.

We’ve ALL got great talks, great slides, great ideas which we share in tutorials, at rounds, at conferences – the ethos of FOAMed is to share this educational content with colleagues around the world.

The concept has been enthusiastically taken on by clinicians in emergency medicine and critical care, who recognise the value of a means of rapidly disseminating information to discuss cutting edge concepts.

Of course once still needs didactic teaching, to read textbooks and to peruse journals as the foundation of medical education – but once one has achieved a degree of competency in the field and is looking to keep abreast of new ideas, FOAMed opens up a world of self-directed learning. It’s for finesse and mastery, not the basics.

Added to this are the advantages of learning asynchronously – listening to a podcast on the morning commute or at the gym…watching a video to reinforce the details of a practical procedure or to watch a conference talk…or even reading clinical conundrums posed on the myriad of EM and CC blogs out there.

As one explores the global FOAMed community, discussions are had with colleagues around the globe, allowing informal ‘corridor conversations’ with like-minded colleagues. Not only that, but experts in various fields give freely of their time and experience – it’s nice to be able to tap into (and even discuss) ideas with people like Karim Brohi, Scott Weingart and so on…

Finally FOAMed helps break down tribalism – we’re all interested in patient care and advancing clinical knowledge (whether our own, or the global sum). Some of the best contributors come not from ‘eminence-based’ medics…but from other arenas. I’ve learned a helluva lot from my colleagues in prehospital care, with many lessons applicable to rural, Ed and ICU environments. Ditto the involvement of nurses, paramedics, students, social workers, administrators – people with a different spin on the work we do.

So – don’t be scared – dive in, explore the FOAMed (free open access medical education).

Gar Pask – Anaesthetic Hero

I’ve been doing a bit of thinking about life-jackets after spending a few hours bobbing around in a heated pool during last week’s HUET (helicopter underwater escape training) course.

Whilst practicing in a pool is one thing, I did wonder how well one would cope if ditching in the cold waters of the Southern Ocean wearing a switlik & flight suit or immersion suit. Probably quite well – modern safety equipment has come a long, long way from it’s origins (the first description dates back to 870 B.C., with a stone carving showing Assur-Nassur-Pals’ army crossing a river wearing inflated animal skins as flotation devices).

“the bravest man in the RAF never to fly an aeroplane”

The development of modern lifejackets includes a vital contribution by British anaesthetist, Edgar ‘Gar’ Pask. His story is fascinating, not least for the fact that, like true eccentrics, he performed experiments using himself as a test subject.

pask03

Pask in flotation device

Pask is famous for having been asleep whilst completing most of the research for his thesis

In essence, Pask made three vital contributions, spurned on in part by necessary developments during WWII.

(i) the problem of ‘downed & drowned’ aircrew

Most of us are familiar with the “Mae West” – a US lifejacket considered the cutting edge in the war years. Whilst it did a great job of keeping downed aircrew afloat, sadly many airmen were found in a face down position. They survived bailing out of their aircraft, but drowned despite being kept afloat.

Edgar Pask was a British anaesthetist, seconded to the Physiological Laboratory in the RAR Research Station at Farnborough, UK under the encouragement of another anaesthetic great, Professor Macintosh. Pask’s doctoral thesis is infamous for being performed with the author mostly asleep – the reason being that Pask used himself as a test subject. He was anaesthetised and placed, unconscious, in a swimming pool whilst on a breathing circuit. By simulating an unconscious airman, Pask and colleagues were able to test a variety of different lifejackets, refining techniques such that modern lifejackets ensure the victim floats face up, rather than risk ending up face down in the Mae West lifejacket.

The video footage of this research is fascinating – a short clip is shown below. The experimental subject is Pask, intubated and breathing ether on a double-lumen, corrugated anaesthetic circuit, the tubing of which was weighted to neutral buoyancy. Essentially a Mapelson D circuit. He was then unceremoniously dunked in the pool, whereby he promptly sank.

(ii) the efficiency of different artificial respiration techniques

If downed aircrew were recovered, many expired when pulled form the water. The real problem here was actually cold water immersion syndrome – the redistribution of blood volume in a weightless water environment meant that cardiac output dropped markedly when aircrew were pulled (usually vertical) from the water. Attempts at artifical respiration were employed – in the 1940s, the Schafer method was most popular.

The second part of the above video shows an anaesthetised Pask undergoing various methods of artificial respiration whilst paralysed (at the 9:08 mark). They demonstrate Silvester’s method, Schafer’s method & Eve’s rocking method. Not currently approved by the Resus Council!

These experiments are remarkable (and a little unsettling) – Pask was paralysed and then underwent two hours of artificial respiration, during which time measurements were made of ventilation rate, tidal volume and O2 consumption. This was in the days before apnoeic diffusion oxygenation!

(iii) high altitude decompression ‘time of useful consciousness’

The RAF leased B17 ‘flying fortress’ bombers from the USA. These lightweight aluminuim-skinned aircraft apparently flew at the height of Everest, unpressurised – posing hazards of cold & hypoxia to the crew. Pask explored the effects of bailing out at such high altitudes – again, using himself and colleagues as test subjects. They were exposed to various hypoxic mixtures in a decompression chamber – the records are disturbing, essentially describing young men being asphyxiated and then allowed to recover.

Here is a description of Gar Pask being asphyxiated, whilst hanging vertical in a parachute harness in a hypoxic mix in a decompression chamber. Extreme hyperbaric medicine!

The period of anxiety was more prolonged than in the ‘descent’ from 55,000 ft, with the subject sitting, and not until the sixth minute was it certain that the ‘descent’ could be completed.

The subject [Pask] made two attempts to raise himself in the harness by pulling on the parachute risers during 1 1/8 to 1 ½ mins. These attempts he could not remember afterwards. At 1 ½ minutes., the subject became limp and relaxed, the head falling forward, but although it must have been merely a matter of chance, it was not thought that laryngeal or pharyngeal obstruction actually developed, although vigorous inspiratory efforts were made.

Sweating was very profuse and liquid sweat fell from the forehead and formed a noticeable pool on the floor. Muscular twitching of the left arm was seen between 5th and 9th minutes. The pulse was not rapid – indeed a good deal slower than in previous ‘descents’ with this subject, but between 2nd and 6th minutes it was recorded as very feeble.

[the experimental record of one of Pask's 'descents']

The upshot of all this was that Pask demonstrated that 30,000 feet was the highest survivable altitude to bail out without supplemental oxygen. I somehow doubt that such experiments would get past a modern day Ethics committee!

Post War Years

Pask’s bravery was recognised with award of the OBE (Military Division) in 1944. His meticulous approach to experimentation ensured the success of his 1947 thesis, although public publication of his wartime research was delayed until 1957, no doubt for both secrecy reasons and also in view of the justifiable outrage concerning similar experimentation on non-willing volunteers by the Nazi’s at Dachau.

It is a tragedy of man’s inhumanity to man that the Luftwaffe used human prisoners in these experiments. An account of the abhorrent work of Nazi Dr Sigmund Rascher is here. A disturbing thought is whether the data from these brutal crimes could be used subsequently – an issue explored in the NEJM. Ironically Rascher was executed on the orders of Himmler, in part for falsifying his data.

Recognising the folly of ongoing human self-experimentation, Pask was instrumental in developing Sierra Sam, the forerunner of modern crash test dummies. This proved a safer method for testing modern lifejackets than anaesthetising Gar Pask!

Pask died in 1966, age 54 – no doubt the toll of a lifelong smoking habit and the high likelihood of aspiration during the ‘flotation tank trials’ contributed to his early demise.

HUET & Lessons for Medicine

I was a little apprehensive about undergoing HUET training, mostly due to some gentle winding up by the likes of Minh le Cong in Queensland & some of the GSA-HEMS mob. Comments about eliciting cremasteric reflexes, sinus douching and so on seemed to be setting the scene – made worse as undertaking HUET in the middle of Adelaide winter.

Augsburg
“Back in the day” – a young Dr Tim posing whilst C1 slalom training – Augsburg, Germany

Actually, I don’t know why I was concerned about being dunked. ‘Back in the day’ I was a keen (and expert) whitewater canoeist. I rose through the ranks in both kayak and canadian classes, competing regularly at premier level in slalom events in the UK and representing my country overseas. Being flipped over in the dark whilst training in the ice cold waters of the Thames weirs or on the grade IV rapids of Scottish rivers was no problem.

Competing at that level of performance, the difference between boat-body-blade was indiscernible, with movements practiced and fluid such that one could quickly (<1 second) roll up from an inverted position with barely an interruption to forward paddling movement.

Augsburg2
Boat-Body-Blade – it’s a bit like Arm-Laryngoscope-Epiglottis

But that was a long time ago. Being stuck inside a metal airframe and dunked upside down is completely different. And unlike a low volume carbon-kevlar canoe, there’s no element of control when a helicopter ditches…

Training took place at the heated (27 degrees, thank you) pool at the Adelaide Dive Centre, under the expert guidance of the team from RHO aviation.

Why bother with HUET?

Brian Burns of Sydney HEMS tweeted this slide today from the concordant HUET exercise in Sydney, demonstrating why it is vital that anyone being transported by a helicopter platform knows what to do in the event of ditching in water.

Slide tweeted from GSA-HEMS training by Brian Burns @HawkmoonHEMS

Whilst it is possible to perform a controlled ditch on water, this will be subject to water conditions, aircraft performance and so on. Some helicopters have floats – but helicopters are inherently top heavy and are highly likely to invert. Or be attacked by sharks as in this clip below from Jaws 2 :

That said, helicopter transfer is reasonably safe. The most pertinent reference that I could find dates back almost 10 years and is from Dave Cooksley and (then registrar) Jim Holland when in Townsville, both nice FACEM chaps. However problems can occur and it makes sense to be prepared. Helicopter Underwater Escape Training (HUET) is designed to improve the chances of surviving a ditching episode.

As can be seen from the footage below, an uncontrolled ditch in water poses risks of disorientation, impact with unsecured equipment and debris from the impact. Add to this the confusing elements of inversion, cold water and poor/zero visibility, and it is easy to see why occupants can become disorientated and fail to survive. Add to this the myriad of different harness & door release mechanisms (over 35 of the latter, with no industry-standard!). HUET training is designed to increase chances of survival in an unlikely emergency.

So what did we learn?

The facilitators from RHO aviation were really good, working through educational material in a solid, stepwise manner with a clear goal (lessons there for meducationalists). They emphasised the importance of a pre-flight safety brief :

  • seat belts
  • loose items (secured)
  • lifejackets
  • identifiying primary & secondary exits, with reference points

It is no secret that I am a fan of checklists in a crisis – when there is time. But the regular performance of a safety brief reinforces safety, mitigates against complacency and is something that I try to instil into the resus bay of my local hospital when awaiting a patient – checkling O2, suction, confirming presence of airway and crash carts, setting up vent and anticipating likely clinical needs…as well as backup plans. Cliff Reid has talked about the value of having a resus room safety officer….perhaps it’s not such a bad idea, especially in EDs where the resus is performed by a flash team (members who may never have worked together, or are used to another ED’s equipment/procedures). Minh le Cong (who never sleeps) has proposed a pre-ED RSI safety brief, albeit tongue-in-cheek.

Once the aircraft inverts, the importance of WAITING for cessation of violent movement was emphasised (to reduce risk of disorientation, injury), then calm performance of a well-rehearsed sequence :

  • orientate (use one hand to anchor as a fixed reference eg: underside of seat, with inboard hand)
  • locate (primary exit, use body movement eg knee or shoulder to locate door, then use outboard hand to locate exit release)
  • release (once exit open, keep outboard hand fixed on frame and then release inboard hand to undo safety harness)
  • vacate (use a low profile, pull inboard hand to join outboard hand at exit & pull head through – body will follow)
  • inflate (clear the surface of debris and inflate lifejacket if safe & appropriate to do so)

It was certainly easiest to perform this drill with eyes shut, avoiding the potential added disorientation of visual cues whilst inverted. Obviously an emergency ditching is a high stress environment – there will be a catecholamine surge and removing factors likely to add to panic is sensible

What’s the parallel in resus? There are probably a few. I was immediately reminded of similarity with CICO crisis training. I’ve had the misfortune of doing a few of these in real life, and have learned (by hard experience) to perform surgical airways as a tactile procedure (scalpel-finger-[bougie]-tube). But body mechanics are important in other things we do – threading a catheter onto a seldinger wire (use palmar aspect of both wrists to form a stable bridge, giving fine motor control) or effective laryngoscopy (understanding different mechanics of Mac 3 vs 4, elbow and wrist position to maximise force – a plug here for Rich Levitan’s airway course which certainly helped my airway technique).

Here’s a demo of the HUET in action – experimental test crash dummy Dr Francis Lockie uses his secondary exit, as the primary exit is blocked.

In summary

Despite the ‘wind up’ about HUET, I thought it was a well run course, delivered exactly what it was supposed to and has given a structure to dealing with a ditching crisis.

Could such lessons be applied to medicine? Absolutely – building muscle memory, relying on simple drills and regular sim are key.

Sabbatical with Retrieval

It’s pretty obvious that I see the benefit of FOAMed for rural doctors as in the ability to ensure rapid knowledge translation, particularly in fast-moving fields such as emergency medicine. Although the work of rural docs encompasses predominantly primary care, our work intersects with emergency medicine when on call for out small rural hospitals…and of course some practice obstetrics, anaesthetics or surgery.

I am keen to apply best evidence to care of the critical patient; caring for these patients is something that rural doctors do relatively infrequently and it can be hard to maintain both skills and knowledge. There are some rural doctors with high end skills (particularly those who practice procedural medicine) – but such work may be very much out of the comfort zone for some doctors working in the country.

It’s very easy to fall into the trap of criticising patient management by others – we’ve all seen (or worse still, been part of) the ‘ICU-puts-down-ED-management-which-puts-down -primary-care-failings‘. It’s easy tribalism. I’ve blogged about this before in the “Be a ZERO not a HERO” post.

Anyone who’s seen the movie ‘Trainspotting‘ will understand this spoof EM leaflet

From http://lifeinthefastlane.com/choose-emergency-medicine/

Whilst there is no shortage of muppetry across disciplines, I am more interested in ways to improve delivery of care in rural Australia, despite the problems of regular skills maintenance, relative infrequency, staffing, equipment and so on. Less criticism and tribalism, more solutions…

FOAMed is one way of helping to rural doctors to avoid being the ‘weak link’ in both EM as well as other areas of medicine. Having excellent support (iCCNet, medSTAR retrieval etc) is essential – but I think it behoves rural docs to avoid a therapeutic vacuum, even whilst awaiting the retrieval ‘cavalry’ to arrive. To whit : doing the simple things, well. Training for the occasional emergency. Using appropriate cognitive aids (action cards, checklists etc). Understanding the value of regular in situ sim-training with all players (doctors, nurses, admin volunteer ambulance officers etc) involved. Critical illness may be infrequent – all the better to be prepared.

Time to learn from the experts…

With this in mind, I am taking 6 months off to work as a retrieval clinician.  MedSTAR, South Australia’s retrieval service have very kindly offered this opportunity and I look forward to soaking up as much knowledge and skills as I can in the time.

Whilst it’s a bit of a jolt (and pay cut!) to move from my own private practice as a rural doctor to a salaried role, I reckon the experience gained will be worth it…

Learning from a high-performance organisation like medSTAR should have flow on benefits to delivery of care in the bush. So I need to get out and learn more…and there is no doubt in my mind that I have lots to learn from the experts in delivering critical care to rural South Australians.

In keeping with SA Health’s social media policy, I won’t be describing any of the cases I am involved with during this time (not that I’d discuss any case on this site, other than ‘hypotheticals’ for education purposes)

There may be an occasional sporadic post on clinical topics of interest to rural clinicians, but I do not expect to post much over the next six months. Ditto use of Twitter under the @KangarooBeach handle, unless appropirate.

So … if you see me in your ED (whether rural or metro) please take time to say “G’day”…

Meanwhile I’ve got HUET training to look forward to….

Snake, Snake, Snake!

No, not a rant about the use of pulmonary artery catheters…was out walking recently & came across this fellow.

OLYMPUS DIGITAL CAMERA

As it’s winter, the snakes come out onto road surfaces to warm up. This is a tiger snake – Kangaroo Island has two snakes, the tiger and the pygmy copperhead. KI tiger snakes don’t have the usual tiger stripes, being black to help absorb heat quicker. As is common with island speciation, the tiger snakes here are larger and more venomous that their mainland counterparts. You can see the ‘hood’ on this fellow as he makes himself appear more threatening.

We don’t see that many snake envenomations locally…the vet sees more, as dogs and snakes don’t mix. Generally snakes will avoid humans…although in the colder months I take especial care when collecting logs from the woodpile, as snakes like to rest there. Come summer, they are generally more active at night – hunting mice and frogs – and occasionally engaging in fights-to-the-death with local Rosenberg’s goanna.

It’s worth thinking about how YOU are going to manage a snake bite in your community – both from immediate first aid (pressure immobilisation, keep still) through to assessment (was this a true envenomation, a ‘dry bite’ or even a ‘stick bite’?) as well as use of snake-venom detection kit to aid decision-making as to which anti-venin to use (clue – if it’s a tiger snake or copperhead, use tiger snake antivenin!) and subsequent resuscitation.

Few quick Qs :

  • who is most likely to get envenomated by snakes?
  • how do you apply pressure-immobilisation?
  • how do determine envenomation or not in a rural setting?
  • how to use a venom-detection kit? to guide choice of antivenin?
  • are there any pitfalls in resuscitation of the snake bite victim?

Rural docs coming along to the RDASA Education Event Aug 8-9th at Wirrina Cove, South Australia will get a chance to quiz Prof Julian White on this topic. I’d recommend the CSL Antivenom Handbook, although I am not at all convinced about counting anal scales in the middle of a resus!

Might also be asking Prof White for his views on use of redback antivenom!

Eminence vs evidence-based medicine? Great review here from AdelaideEmergencyPhysicians.

 

The More I Know, The Less Certain I Am

I’ve recently had cause to re-examine Dale Edgar’s ‘Cone of Experience‘. Like that fabulous educator from iTeachEM, Rob Rogers (@EM_Educator), this concept seems intuitive and demonstrates nicely the benefit of learning via different formats. I use it in talks to explore different learning styles.

Screen Shot 2014-07-24 at 3.28.00 pm

Except it’s bunk. Dale never ascribed percentages to the retention rate for each different mode of learning; rather the ‘cone of experience’ demonstrates the varying abstraction potential for each learning mode. Understanding that Dale’s model was centred around understanding the concretness of different material, not retention rates.

Why is this important? Because it’s not uncommon in medicine to come across the view that “there is only one correct way to do X

When I was a junior, following such rules made sense – they reduced the burden of having to ‘think’ too hard … and when such rules were imposed from a higher authority (invariably a gruff Consultant), failure to comply risked raising their ire! Of course it’s not just lack of years or having a steep authority gradient that encourages sticking to such rules. As humans we tend to seek the comfort of familiarity and our own experience when making decisions – hence the “I’ve always done it this way…” or “Textbook X (authored by eminent expert Y) tells us to do it this way, so I’m sticking with that…” or even the “The teaching is to do procedure X this way – anything else is negligent” conundrums.

Nowadays when someone asks me how to do something, I seem to find myself pausing more and more as I reflect on previous experience. No longer do I say “Chest drains? They’re easy, let me show you how” – instead I pause “Well…it can be difficult…let’s talk about it, then I’ll help & guide you through one” as I recall not the vast majority of easy ones, but the difficult cases, the errors made, the complications…and am keen to relay this tacit experience bro e through mistakes to my colleague.

Some recent debates on social media have been relevant. Over on doctors.net.ukfora, we’ve had examples of :

- experienced clinicians ‘told off’ by physios for eliciting lower limb reflexes in a seated patient “the ONLY way to do reflexes is with patient laying down”

- anaesthetists laying into emergency physicians over options for safe sedation of the haemodynamically compromised patient in VT (with the usual cliched ‘needs RSI‘, through ‘mustn’t use ketamine because of strain on heart‘ through to ‘just zap them and apologise‘). Kudos to Cliff Reid & Ed Valentine for keeping their cool in that debate!

Meanwhile there’s been a useful Twitter and Google+ exchange on dogma around use of femoral traction devices (FTDs) for splinting of femoral fractures in the presence of a pelvic fracture

There are plenty of other discussions that crop up – cricoid force, checklists for crisis, thrombolysis in stroke, acceptable modifications to RSI etc etc

In all of these discussions, it’s not uncommon to see people looking for “rules”. In the recent examples,

- physio wanted a rule that all lower limb reflexes are elicited in supine patient

- anaes colleagues wanted to use propofol RSI for the patient in VT and berated use of ketamine

- traditional teaching is to avoid use of FTD in presence or suspected presence of pelvic fracture; some paramedics were lookign for guidance on rules whether to use a FTD or not. Wise words from experienced paramedic/retrieval practitioner Dave Tingey “clinical judgement is the key – especially where there is little or no evidence” – he emphasised focussing on patient outcome, not rules for a process!

FOAMed – tacit knowledge sharing with global community

People ask me why I use social media for learning. For me the attraction of FOAMed is that it addresses the issues where there is clinical uncertainty. If you are looking for absolutes (as when learning the craft of medicine or to pass exams) then stick to the textbook teachings. If you are looking to test yourself and continue to explore the expanding frontiers of knowledge, then use FOAMed. It opens up the world of #dogmalysis and enables corridor conversations with clinicians worldwide. Some of what you encounter is bunk…some is golden. The trick is to filter, engage, question and unlike politicians, don’t stick to one party line.

Even if “the more you know, the less certain you are!”
