Convergent Evolution in the Jungles of Critical Care

boss-of-the-mob-1400090-1279x1923By Stuart Duffin
Expat Brit, intensive care physician and anaesthetist at Karolinska University Hospital in Stockholm, Sweden. Stuart trained in the UK, and spent some time working Australian emergency departments.

One of the most striking things for me about our new/old pan-specialty of critical care, brought into focus by the world-shrinking effects of FOAM and twitter, is just how differently it falls into the domains of the established specialities in different parts of the world. This leads inevitably to comments like, “emergency physicians shouldn’t intubate”, “anaesthetists cant do sick”, “nurses cant be doing such and such”, and so on. All of these statements are clearly equally rubbish because obviously, in certain parts of the world, they do. And they do it really well. Sure there are differences between countries and continents, populations and environments, but when it comes down to it, it doesn’t matter where you are, people still get sick, infected, pregnant, run over, stabbed or hit around the head with heavy things.

All over the world, in our previously quite isolated environments, these same ‘selection pressures’ have forced healthcare providers to evolve by the process of convergent evolution. Although obviously not strictly darwinian, the undeniable effects of simultaneous evolution by survival of the fittest-to-practice can be seen.

Convergent evolution is the process by which, in different parts of the world, completely different species have evolved in parallel to fill similar roles and have similar features. It didn’t matter whether it was a deer, a wildebeest or a kangaroo, there was a vacancy for a fairly big animal who liked eating grass and moved in big groups, and someone stepped up.

Unsurprisingly, critical care resuscitationists are also a little different from country to country and from continent to continent. They have different titles and work in slightly different ways. But when you really look at a critical care doc in action, or talk to one, or follow one on Twitter, we are all cut from the same cloth. I would argue that FOAM has created a critical care zoo in which the kangaroos and antelopes, lemurs and monkeys, aardvarks and echidnas and anaesthetists and emergency physicians are all chucked into the same cage. They’re all looking at each other thinking, “you look like me, but somehow not. We seem to do the same stuff, but we’re not identical – it cant be right!”.

In The United States, the idea of an anaesthetist doing a clamshell thoracotomy would be a little strange. In Scandinavia, an emergency physician doing central lines and fiberoptic intubation in resus would be just as eyebrow raising. A Swedish intensivist and anaesthetist spent some time working in Australia as an ICU senior reg. When attending a patient in resus the emergency physician there announced “we need an airway guy”. My colleague answered “I’m the airway guy”. “No an anaesthetist” replied the emergency physican. “I am an anaesthetist!” “No an….” and so it went on.

The effects of this process are of course by no means limited to doctors. Nurses, paramedics and physiotherapists are all part of this still changing ecosystem. A colleague of mine was showing a visiting Australian emergency physician our trauma bay and describing how major trauma is managed here without the involvement of emergency physicians at all. “When it’s really urgent, it’s anaesthesia and surgery” he explained. I wonder how that went down? There is an element of truth to the statement but the words are wrong. It should have been “When it’s really urgent, it’s airway, access, transfusion, invasive procedures and resuscitation thinking”.

The job title of the person who actually holds the knife/laryngoscope/needle and has what it takes to get it done isn’t important. When the push comes to shove and the bad stuff bounces off the fan, it’s more about skillset and mindset, and less about the collection of letters under your name on your badge, or after your name on your CV.

Resuscitationist lessons from a self-protection master

UCIt’s better to have it and not need it, than to need it and not have it

My great friend and fellow Brit Lee Morrison is in Sydney again, teaching people how to save lives. Like a resuscitationist. But Lee isn’t a health care worker. He is a professional self protection instructor and martial athlete. The lives he is teaching people to save are their own and those of their friends and families. Lee has travelled the world and taught a diverse range of professionals including law enforcement and military special forces personnel. His current world tour will include the Czech Republic, USA, France, Russia and Germany after Australia.

What does this have to do with resuscitation? In my experience, almost everything. Hitting someone in self defence is technically very easy. Doing a resuscitative hysterotomy is technically very easy. Being able to do either of those things under stress can be difficult or impossible for some people.

Those who strive to understand and cultivate the Mind of the Resuscitationist know the importance of preparation through simulation under stress; the need to acknowledge and control the physiological and emotional response to stress; the necessity to train outside ones comfort zone and minimise the gap between simulated and real situations by optimising the cognitive fidelity of training scenarios; and the requirement to access the right mental state in an instant in which failure is not considered to be an option.

People who do not wish to witness the discussion or demonstration of violence or who cannot stand swearing should stop now. Those of you who want to see mastery in action watch the video below of Lee teaching in Germany.

I want you to appreciate the following:

  • Presentation style – how to connect with an audience and fully engage them through humour, passion, emphasis, intelligent discourse, and detailed explanations that connect emotionally and physically as well as intellectually.
  • The loss of fine motor skill under stress (2 min 13 sec)
  • The mindset of determination (2 min 48 sec) – consider how this relates to the perspective of the resuscitationist prepared to do a resuscitative thoracotomy under stress
  • How to influence and win arguments in a conflict situation by being assertive but providing a face-saving get-out for the aggressor. I have applied this multiple times in the resus room and in retrieval situations. (4 min 11 sec)
  • Training honestly – maintaining safety but ‘doing it like you f—-ing mean it’. Get out of your comfort zone and make the discomfort as real as possible. (7 min 37 sec)
  • How to minimise the gap between your training and what you’re training for, when legal, moral, and safety restrictions prevent you from doing the actual task for real as a training exercise. Using fatigue, pain, and disorientation as perturbations so you learn to recognise and mitigate their effects. (9 min 19 sec)
  • Accessing a single mental state that provides focus and prevents distraction from discomfort (11 min 40 sec)

If the video made you feel uncomfortable ask yourself why. If it’s because you consider yourself to be above violence and find the subject matter, language, and humour to be distasteful, that’s your right to feel like that. But try to dig a little deeper and ask yourself whether there are potential situations in your life that could confront you with fear or pain that you could be better prepared for if you trained with a different mindset.

When the situation arises that demands life-saving action and you are tired, hungry, scared, and discouraged by opposing advice or opinion, do you have the self-knowledge and resilience to see it through? If you don’t know the answer to that, isn’t it time you found out?

Resus Team Size and Productivity

paedsimiconA paediatric trauma centre study showed that in their system, seven people at the bedside was the optimum number to get tasks done in a paediatric resuscitation. As numbers increased beyond this, there were ‘diminishing marginal returns’, ie. the output (tasks completed) generated from an additional unit of input (extra people) decreases as the quantity of the input rises.

The authors comment that after a saturation point is reached, “additional team members contribute negative returns, resulting in fewer tasks completed by teams with the most members. This pattern has been demonstrated in other medical groups, with larger surgical teams having prolonged operative times and larger paramedic crews delaying the performance of cardiopulmonary resuscitation.

There are several possible explanations:

  • crowding limits access to the patient or equipment;
  • “social loafing”- staff may feel less accountable for the overall group performance and less pressure to accomplish individual tasks;
  • seven is the number recommended in that institution’s trauma activation protocol, with optimal role allocation described for a team of that size;
  • teams with redundant personnel may experience role confusion and fragmentation, resulting in both repetition and omission of tasks.

In my view, excessive team size results in there being more individuals to supervise & monitor, and hence a greater cognitive load for the team leader (cue the resus safety officer). More crowding and obstruction threatens situational awareness. There is more difficulty in providing clear uninterrupted closed loop communication. And general resuscitation room entropy increases, requiring more energy to contain or reverse it.

However, for paediatric resuscitations requiring optimal concurrent activity to progress the resuscitation, I do struggle with less than five. Unless of course I’m in my HEMS role, when the paramedic and I just crack on.

Factors Affecting Team Size and Task Performance in Pediatric Trauma Resuscitation.
Pediatr Emerg Care. 2014 Mar 19. [Epub ahead of print]


OBJECTIVES: Varying team size based on anticipated injury acuity is a common method for limiting personnel during trauma resuscitation. While missing personnel may delay treatment, large teams may worsen care through role confusion and interference. This study investigates factors associated with varying team size and task completion during trauma resuscitation.

METHODS: Video-recorded resuscitations of pediatric trauma patients (n = 201) were reviewed for team size (bedside and total) and completion of 24 resuscitation tasks. Additional patient characteristics were abstracted from our trauma registry. Linear regression was used to assess which characteristics were associated with varying team size and task completion. Task completion was then analyzed in relation to team size using best-fit curves.

RESULTS: The average bedside team ranged from 2.7 to 10.0 members (mean, 6.5 [SD, 1.7]), with 4.3 to 17.7 (mean, 11.0 [SD, 2.8]) people total. More people were present during high-acuity activations (+4.9, P < 0.001) and for patients with a penetrating injury (+2.3, P = 0.002). Fewer people were present during activations without prearrival notification (-4.77, P < 0.001) and at night (-1.25, P = 0.002). Task completion in the first 2 minutes ranged from 4 to 19 (mean, 11.7 [SD, 3.8]). The maximum number of tasks was performed at our hospital by teams with 7 people at the bedside (13 total).

CONCLUSIONS: Resuscitation task completion varies by team size, with a nonlinear association between number of team members and completed tasks. Management of team size during high-acuity activations, those without prior notification, and those in which the patient has a penetrating injury may help optimize performance.

Family presence during resuscitation

CPR-iconFamilies allowed to be present during attempted cardiopulmonary resuscitation had improved psychological outcomes at ninety days.

Adult family members of adult patients were studied in this randomized study from France.

Resuscitation team member stress levels and effectiveness of resuscitation did not appear to be affected by family presence.

Family Presence during Cardiopulmonary Resuscitation
N Engl J Med. 2013 Mar 14;368(11):1008-18


BACKGROUND: The effect of family presence during cardiopulmonary resuscitation (CPR) on the family members themselves and the medical team remains controversial.

METHODS: We enrolled 570 relatives of patients who were in cardiac arrest and were given CPR by 15 prehospital emergency medical service units. The units were randomly assigned either to systematically offer the family member the opportunity to observe CPR (intervention group) or to follow standard practice regarding family presence (control group). The primary end point was the proportion of relatives with post-traumatic stress disorder (PTSD)-related symptoms on day 90. Secondary end points included the presence of anxiety and depression symptoms and the effect of family presence on medical efforts at resuscitation, the well-being of the health care team, and the occurrence of medicolegal claims.

RESULTS: In the intervention group, 211 of 266 relatives (79%) witnessed CPR, as compared with 131 of 304 relatives (43%) in the control group. In the intention-to-treat analysis, the frequency of PTSD-related symptoms was significantly higher in the control group than in the intervention group (adjusted odds ratio, 1.7; 95% confidence interval [CI], 1.2 to 2.5; P=0.004) and among family members who did not witness CPR than among those who did (adjusted odds ratio, 1.6; 95% CI, 1.1 to 2.5; P=0.02). Relatives who did not witness CPR had symptoms of anxiety and depression more frequently than those who did witness CPR. Family-witnessed CPR did not affect resuscitation characteristics, patient survival, or the level of emotional stress in the medical team and did not result in medicolegal claims.

CONCLUSIONS: Family presence during CPR was associated with positive results on psychological variables and did not interfere with medical efforts, increase stress in the health care team, or result in medicolegal conflicts.

Upstairs vs Downstairs: an EPIC Conundrum

A new breed, and new terminology

USAflagb&WResusScott Weingart MD and colleagues have published a discussion paper [1] outlining the role of emergency physicians who have completed additional critical care training – ED intensivists – and the potential benefits these individuals might bring to patients, emergency departments, and their emergency physician colleagues.

The paper also introduces a glossary of new terms which might help clarify future discussion of this practice area:

Emergency medicine critical care a subspecialty of emergency medicine dealing with the care of the critically ill both in the ED and in the rest of the hospital
EP intensivist a physician who has completed a residency in emergency medicine and a fellowship in critical care
ED critical care emergency medicine critical care practiced specifically in the ED
ED intensivist (EDI) EPIs who practice ED critical care as a portion of their clinical time
Resuscitationists EPs who have additional knowledge, training, and interest in the care of the critically ill patient
EDICU a unit within an ED with the same or similar staffing, monitoring, and capability for therapies as an ICU
RED-ICU a hybrid resuscitation area and EDICU allowing a department to adopt the ED intensive care model with minimal cost and no changes to the physical plant

Potential benefits of ED-intensivists – and associated adequately staffed areas within ED that facilitate ongoing critical care delivery – include:

Full intensive care provided to patients unable to be moved to ICU (usually due to bed unavailability)
Development of protocols and care pathways that allow other EPs to deliver enhanced critical care
Gaining of advanced skills for ED nurses
Removal of need for ICU bed for conditions that can be improved in a few hours (eg. some overdoses, DKA, acute pulmonary oedema)
Cost saving due to decreased ICU stay (if the above ‘short term critical care’ patients are admitted to ICU, ward bed unavailability can make it difficult to discharge them from ICU)
Additional airway skills in ED (and training around that)
Improved invasive and non-invasive ventilatory management (and training) in ED
Gaining of ED experience in ventilator weaning and extubation
Gaining of ED experience in haemodynamic monitoring, vasoactive support, and even mechanical circulatory support (balloon pumps and ECMO)
Improved sepsis care
Improved post-cardiac arrest care
Improved trauma management
Greater exposure to invasive procedures
Improved end of life care
Better critical care exposure for trainees

Improved ED-ICU communication and shared protocols

Scott’s whole mission is about bringing ‘upstairs care downstairs’, and educating others to do that, at which he is a true master. No doubt he will singlehandedly have inspired a large cohort of emergency physicians to train in critical care. Examples of ED intensivists and their roles are listed here on the EMCrit site.

Emergency physician intensivists in the Old Country

epic__logoUKflagAs an ‘ED-intensivist’ myself, I do believe many of those advantages can be realised. In the UK when I originally trained in both EM and ICM there was a small number of similarly trained individuals and we collectively called ourselves ‘EPIC’ – ‘Emergency Physicians in Intensive Care’.

Our shared energy and enthusiasm led to a dedicated conference in 2011 and it’s possible that our proselytizing combined with publications like Terry Brown’s ‘Emergency physicians in critical care: a consultant’s experience‘[2] may have made some small contribution to the subsequent explosion in interest in dual accreditation in EM & ICM in the UK.

Disappearing upstairs

AusflagWhen I moved to Australia in 2008 I was excited to hear that emergency docs now made up the largest proportion of dual trained new intensivists. When I asked a leading member of this group whether he saw any role for an ‘EPIC’ community in Australia I was surprised and disappointed with the response:

‘Nice idea but I don’t see the point. I can’t think of anyone who dual trained who’s still working in emergency medicine’

So it seems those who were in the best position to bring upstairs care downstairs had all disappeared upstairs. Many will admit it’s not just because they find critical care more interesting than emergency medicine; the combination of a significantly higher income (through private practice) with better working conditions plays a significant role.

There are other opportunities in Australia for emergency physicians to practice critical care. Prehospital & retrieval medicine services undertake interhospital critical care transport of patients from small and often remote facilities where all of the first few hours of intensive care must be delivered by retrieval teams in often challenging environments with limited personnel and equipment. In some cases it’s these retrieval physicians who are able to fulfil the role of ED-intensivist in their own EDs.

Integrated critical care models and SuperDoctors

ChrisTIconAnother Australian example is the ‘integrated critical care’ model pioneered in some regional centres in rural New South Wales where emergency physicians with critical care training aim to provide seamless care to patients in the prehospital, ED, ICU and ward environments. I was lucky enough to do some locum shifts in one of these centres – Tamworth – where the service is delivered by some of the most highly skilled and dedicated physicians I’ve ever met. Check out their registrar job ad for a flavour of their work. This model was described in a 2003 publication[3] by my Sydney HEMS colleague Craig Hore which lists its features as follows:

Features of integrated critical care
Multiskilled critical-care specialists trained and experienced in the various aspects of critical care in rural hospitals.

Multidisciplinary critical-care teams that provide:

A more seamless interface between the various phases of critical care and between its respective disciplines;

A rapid response to, and a continuum of care for, critically ill and injured patients;

Clinical leadership in evaluating and managing critically ill and injured patients, both in the hospital (including the emergency department, critical-care unit and hospital wards) and in the community (including retrievals, and support for ambulance crews, peripheral hospitals and general practitioners); and

Training of medical students, medical staff, nursing staff and allied health professionals to recognise and provide a systematic approach to critical illness and injury.

Team members who are empowered to work beyond perceived traditional boundaries, but within the realms of their clinical expertise and credentials, to enable the best use of available resources.

So it appears the benefits to patients, hospitals, and team skills of ED-intensivists have been espoused for some years in the Anglo-Australian setting, and different practice models evolve to best serve local need.

Resuscitating the resuscitationists

UKflagIs it time to revive EPIC? I chased up my UK buddies who co-founded it, and here are extracts from their replies (note ‘CCT’ refers to certificate of completion of training – the UK equivalent of specialist accreditation or board certification):

“Interesting to hear that most Aussies leave EM, my experience of [our regional] trainees is the opposite; of 4 EM / ITU dual CCT over last 5 years, I’m the only one still doing a little bit of CCM, the rest have all ended up in full time EM posts, despite all doing periods of locum consultant work in CCM. (Although, after last 4 winter months of UK EM, I’m beginning to appreciate that I backed the wrong horse! (In the wrong country!!))”
“Having recently dropped ICU/ED 40/60 mix for full time ED i think those gravitating to ICU have a point – an error on my part. The ED represents much more intense work with fewer staff and a work load that far far exceeds resources. As such time to deliver care falls and skills with it. I have just spend 5 weeks [overseas]. I spent time with several directors who pointed out they no longer look to the UK for high quality ED docs as they manage depts as opposed to caring for patients, lack critical care skills and lack the experience to review and manage patients as they improve or deteriorate – a sad state of affairs indeed.”
“I would like to see EPIC back in force and do see an increasing role. around 1 in 4 of our trainees here are looking to joint qualify and we have 3 in their last 2 years. two are currently looking for posts but struggling to find any with a 50-50 mix and are been told to choose one or the other both by prospective ED and ICU employers.”
“I am concerned that dual trained folk here will, like in Australia gravitate to ICU. Whether that is a reflection of where EM is currently in the UK or a personal reflection I’m not sure. Where as I still have days in the ED where I come home and think ‘best job in the world’ these are overshadowed by the stresses of trying to deliver quality care in a failing system. My impression is that urgent care in the UK may well implode soon as ever decreasing workforce meets an over increasing work load. Inevitable closures of units will speed up this process. I currently have a 50/50 ICM/ED job split but that might change to become more ICU.”
“The ED/ICU community in the UK is growing and it wlll be interesting to see the effect of the ICM CCT has on this. There is sadly still a paucity of ED/ICU jobs in the UK and we probably missed a trick with the trauma centres.”
“It would be great to re-create EPIC to make it a real player for the future.”

So it appears emergency physician intensivists are growing in number, but employment prospects in both specialties are not guaranteed. If we are to recruit them to work as ED intensivists (ie. providing critical care in the ED) we have a challenge in making such posts attractive and sustainable. Emergency medicine in the UK is suffering at the moment, and we’ll have to work hard to stop those who are dual trained from disappearing upstairs.

Your comments on this are invited. Should there be more critical care- trained EPs? Shouldn’t ALL EPs have the right critical care skills to manage the first few hours of critical care? Can you call yourself an emergency physician and not be a ‘resuscitationist’? Where do retrievalists fit into this spectrum? How do we help motivate those who are dual trained to stay in the ED for some of their time? Is there a need for a body like EPIC to guide those who are considering dual training, and to provide recommendations to employers and physicians on models of care and job planning? I would love to get more of an international perspective on this issue.

There is a growing interest in the interface between emergency medicine and critical care medicine. Previous articles in this journal have looked at the opportunities and advantages of training in critical care medicine for emergency medicine trainees. In the UK there are a small number of emergency physicians who also have a commitment to critical care medicine. This article describes a personal experience of such a job, looking at the advantages and disadvantages. Depending upon future developments in the role of emergency medicine in the UK, together with the proposed expansion in critical care medicine, such posts may become more common.

3. Integrated critical care: an approach to specialist cover for critical care in the rural setting
Med J Aust. 2003 Jul 21;179(2):95-7


Critical care encompasses elements of emergency medicine, anaesthesia, intensive care, acute internal medicine, postsurgical care, trauma management, and retrieval. In metropolitan teaching hospitals these elements are often distinct, with individual specialists providing discrete services. This may not be possible in rural centres, where specialist numbers are smaller and recruitment and retention more difficult. Multidisciplinary integrated critical care, using existing resources, has developed in some rural centres as a more relevant approach in this setting. The concept of developing a specialty of integrated critical-care medicine is worthy of further exploration.

Beherrsche die Reanimation

TLsm-icon The whole purpose behind my career and this blog is to save life. Like most emergency physicians I don’t see a huge number of resuscitation patients myself in a given week, so my best hope in making a difference is to develop my teaching skills so that I can motivate and inspire others to improve their ability to manage resuscitation.

The highlight of my week therefore has been the receipt of some email feedback from a colleague in Germany. An intensivist, internist, and prehospital doctor (I like him already) who tells me he found my ‘Own the Resus‘ talk helpful:


Dear Dr. Reid,

Few days ago, too tired too sleep after a long shift on my ICU (18 beds internal medicine ICU, I am specialist in internal medicine specialized in intensive care and prehospital emergency medicine in a major German city) I watched your talk via emcrit podcast. I was immediately caught, I soaked in every word, I was fascinated, watched it twice in the middle of the night and next afternoon I listened to it in my car driving to work.

At this very day I did some overdue crap beyond the end of my shift when I heard the ominous shuffling of feet and rolling of the emergency cart from the other end of the ward… “I think we need your help….”

There it was, difficult airway situation. Patient crashing.

Then what followed was a kind of “out of body experience”. I did what was necessary, made things happen like calling anesthesia difficult airway code, calling the surgeons, organizing fiber optics and meanwhile trying to secure that airway myself until i could dispatch anesthesia to the head and surgeons to the neck. Within few minutes there were 6 doctors and 5 nurses shuffling on 9 square meters…

I found myself 1 meter behind the foot end of the pts bed and with your talk in my head I found me consciously controlling the crowd. There was suddenly the messages of your talk and there was me. I don’t know how to put it into words, I wouldn’t have done something else in medical terms but thanks to your talk I had the vocabulary, the tools to reflect myself as the leader to be in charge of the situation somehow with more distance, and after a successful resus the 10 people involved in this code went off with a good feeling that everybody contributed in what they could and all for the pts benefit.

Your talk was a kind of transition to the next level for me: from the colleague who asks how to get out of trouble in many situations because he was often deeply in trouble, to the one who leads out of trouble.

With your talk many things suddenly became clear and I am looking forward to be able to work harder on this role of leading.

Thank you very much.

Speeding things up through equipment design

Ever been at a cardiac arrest resuscitation where someone’s opening and closing drawers at great speed but failing to retrieve the drugs or equipment you’ve asked for urgently?

What if your resus trolley were designed by team of clinicians, engineers, and designers? Such a project was achieved through a collaboration between Imperial College London and the Helen Hamlyn Centre for Design, and the award-winning result was called the ‘Resus:Station’.

The trolley separates into three trolleys for airway, drugs and defibrillation, and circulation. The contents are visible from the outside.

Image from Pubmed Free Full Text Article

As well as improving access to equipment, the trolley can log the team’s actions during each resuscitation attempt. It can also provide an instant display of its readiness for use by recording the removal and replacement of each item.

In a randomised comparison with a standard resus trolley, a number of measures of efficiency and team performance were significantly better using the Resus:Station during simulated cardiac arrest resuscitations.

It appears to be specifically designed for cardiac arrest situations rather than ‘resus’ in its wider context. The most recent article (cited below) reports that a newer prototype is being developed prior to the manufacture of the final product.

For an in depth discussion of how resus room layout can optimise efficiency, check out Minh Le Cong’s PHARM blog and podcast with James French and Scott Weingart on Clinical Logistics

The “Resus:Station”: the use of clinical simulations in a randomised crossover study to evaluate a novel resuscitation trolley.
Resuscitation. 2012 Nov;83(11):1374-80 Free full text

BACKGROUND AND AIM: Inadequately designed equipment has been implicated in poor efficiency and critical incidents associated with resuscitation. A novel resuscitation trolley (Resus:Station) was designed and evaluated for impact on team efficiency, user opinion, and teamwork, compared with the standard trolley, in simulated cardiac arrest scenarios.

METHODS: Fifteen experienced cardiac arrest teams were recruited (45 participants). Teams performed recorded resuscitation simulations using new and conventional trolleys, with order of use randomised. After each simulation, efficiency (“time to drugs”, un-locatable equipment, unnecessary drawer opening) and team performance (OSCAR) were assessed from the video recordings and participants were asked to complete questionnaires scoring various aspects of the trolley on a Likert scale.

RESULTS: Time to locate the drugs was significantly faster (p=0.001) when using the Resus:Station (mean 5.19s (SD 3.34)) than when using the standard trolley (26.81s (SD16.05)). There were no reports of missing equipment when using the Resus:Station. However, during four of the fifteen study sessions using the standard trolley participants were unable to find equipment, with an average of 6.75 unnecessary drawer openings per simulation. User feedback results clearly indicated a highly significant preference for the newly designed Resus:Station for all aspects. Teams performed equally well for all dimensions of team performance using both trolleys, despite it being their first exposure to the Resus:Station.

CONCLUSION: We conclude that in this simulated environment, the new design of trolley is safe to use, and has the potential to improve efficiency at a resuscitation attempt.
