Crisis. Check.

I’m a big fan of checklists, and I think they’re seriously under-utilised in medicine.  Anyone who’s had anything to do with aviation knows that pilots rely on checklists to ensure that important steps aren’t missed, regardless of whether the procedure being performed is routine (take-off, landing) or extra-ordinary  (smoke in the cockpit, double engine failure).  While anaesthetists and. as a result, surgeons have increasingly adopted checklists for routine aspects of surgery (The WHO surgical safety checklist for example) but there still seems to be a reluctance to use checklists in a crisis.  I’ve heard people say “there isn’t time for a checklist” or, even worse “I’m a specialist, I don’t need a checklist to manage a crisis.”

In my humble opinion, if a pilot has time to use a checklist while plummeting towards the ground, a doctor has time to use a checklist while dealing with a crisis that he or she may not have dealt with for years, if ever.  The main image of this post is from the Apollo 13 mission, where a series of checklists saved 3 astronaut’s lives in a situation of extreme pressure and very high cognitive loads.

Atul Gawande (@Atul_Gawande)is an American surgeon who should really need no introduction.  He is the Author of many books and essays commenting on organisation aspects of medicine, and my favourite would have to be “The Checklist Manifesto” which should be compulsory reading for all staff in critical care.

He and his team from Harvard published a neat little study today in the NEJM (Alas, subscription required) comparing performance of an operating room team in simulated crisis scenarios with and without a checklist.  The results speak for themselves.  Those teams using the checklist missed 6% of steps in the management of a complex emergency like massive haemorrhage while those without the checklist missed 23% of steps.  The full checklists are available in the supplementary appendix of the article.  As all good checklists should be, they’re simple, colourful and to the point.  Gawande’s team also have a website, projectcheck.org where, in the spirit of FOAMed, they’re making checklists freely available and providing a forum for others to upload checklists that they have developed.

Of course there is already an example of checklist use in a high pressure scenario that is becoming increasingly ubiquitous – thePrehospital RSI checklist that is used by HEMS the world over.  It is a simple method of ensuring that not only the right equipment is available for a common yet complex and risky procedure, but that clinicians are cognitively prepared to use rescue equipment such as the surgical airway kit.  Many HEMS physicians are now bringing the RSI checklist into their in-hospital practice, and it seems that it is being well received. Toby Fogg (@TobyF) and his colleagues from Royal North Shore Hospital ED in Sydney have developed an ED airway registry and have a great website on which the have a copy of their in-hospital RSI checklist.   Of course clinicians in prehospital care have, in a way, been using checklists for years.  Most EMS systems issue pocket sized guides to their clinical guidelines and it is common practice for paramedics and EMTs to pull them out to refer to while treating a patient.  These guides, while not checklists, are still useful aide memoirs.

Another criticism of the checklist is that if there is only one provider present (rare in-hospital, but not uncommon prehospital) then the checklist will either take too long, or be performed poorly, with steps being skipped while the clinician’s attention is divided.  Again, we can look to aviation for a potential solution.  Many single pilot aircraft have an automated checklist system which reads the steps out in a voice that sounds alarmingly like Stephen Hawking.  Now how can medicine not be improved if Stephen Hawking is your wingman?  A smartphone or tablet based automated crisis checklist could be the answer for solo providers.

Hopefully in the near future the “doctor knows best” attitude in medicine will be a thing of the past and teams caring for critically ill patients will be using checklists all the time to guide and prompt their management of both common and uncommon crises.  I’ve been working on my own set of ICU checklists for a while and I’d be keen to hear from people who have used checklists like the prehospital RSI checklist or who have developed their own crisis checklists.

Here’s the abstract of the NEJM study.

BACKGROUND
Operating-room crises (e.g., cardiac arrest and massive hemorrhage) are common events in large hospitals but can be rare for individual clinicians. Successful management is difficult and complex. We sought to evaluate a tool to improve adherence to evidence-based best practices during such events.

METHODS
Operating-room teams from three institutions (one academic medical center and two community hospitals) participated in a series of surgical-crisis scenarios in a simulated operating room. Each team was randomly assigned to manage half the scenarios with a set of crisis checklists and the remaining scenarios from memory alone. The primary outcome measure was failure to adhere to critical processes of care. Participants were also surveyed regarding their perceptions of the usefulness and clinical relevance of the checklists.

RESULTS
A total of 17 operating-room teams participated in 106 simulated surgical-crisis scenarios. Failure to adhere to lifesaving processes of care was less common during simulations when checklists were available (6% of steps missed when checklists were available vs. 23% when they were unavailable, P<0.001). The results were similar in a multivariate model that accounted for clustering within teams, with adjustment for institution, scenario, and learning and fatigue effects (adjusted relative risk, 0.28; 95% confidence interval, 0.18 to 0.42; P<0.001). Every team performed better when the crisis checklists were available than when they were not. A total of 97% of the participants reported that if one of these crises occurred while they were undergoing an operation, they would want the checklist used.

CONCLUSIONS
In a high-fidelity simulation study, checklist use was associated with significant improvement in the management of operating-room crises. These findings suggest that checklists for use during operating-room crises have the potential to improve surgical care. (Funded by the Agency for Healthcare Research and Quality.)

  1. Couldn’t agree more.

    Medical critical care environments are frequently compared with aviation. Many are quick to dismiss the analogy for a multitude of reasons, but examples such as these are patently obvious. What is less clear are the reasons we so stubbornly refuse to acknowledge potentially life saving practices founded in the aviation industry.

    Checklists are but one example of this, and as you rightly say, if a pilot can do it while under immediate threat of life, what’s stopping us?

  2. I’m all for checklists.. Given our ICU now has a simulation set up the development and utelisation of checklists through use of SIM is a great safe learning environment for nurses and doctors of all levels to become familiar with them leading up to rolling them out in the floor..

    I think checklists in a inhospital crisis can mean roles are made clear and communication is effective.. Therefore hopefully improving patient outcomes
