New research has concluded a specifically-designed video game improves doctors’ ability to recognise when patients need to be transferred to a severe trauma centre.
The research, by the University of Pittsburgh School of Medicine and published today in the BMJ, revealed the game Night Shift was better at preparing doctors to recognise patients who needed higher levels of care than reading traditional educational materials.
This was the case even though doctors who were made to play the game, in which doctors play as a fictitious, young emergency physician treating severe trauma patients, enjoyed it less than those who were asked to read relevant materials.
“Physicians must make decisions quickly and with incomplete information. Each year, 30,000 preventable deaths occur after injury, in part because patients with severe injuries who initially present to non-trauma centres are not promptly transferred to a hospital that can provide appropriate care,” said the game’s creator Deepika Mohan, MD, MPH and assistant professor in Pitt’s departments of Critical Care Medicine and Surgery.
“An hour of playing the video game recalibrated physicians’ brains to such a degree that, six months later, they were still out-performing their peers in recognising severe trauma.”
Night Shift was designed by Mohan to tap into the part of the brain that uses pattern recognition and previous experience to make snap decisions by using subconscious mental shortcuts – a process called heuristics.
Doctors in non-trauma centres typically see only about one severe trauma per 1,000 patients. As a result, their heuristic abilities can become skewed toward obvious injuries such as gunshot wounds, and miss equally severe traumas such as internal injuries from falls.
On average, 70% of severely injured patients who present to non-trauma centres are under-triaged and not transferred to trauma centres as recommended by clinical practice.
“There are many reasons beyond the doctor’s heuristics as to why a severe trauma patient wouldn’t be transferred to a trauma centre, ranging from not having an ambulance available to a lack of proper diagnostic tools,” said Mohan.
“So, it is important to emphasize that recalibrating heuristics won’t completely solve the under-triage problem and that the problem isn’t entirely due to physicians’ diagnostic skills. But it’s heartening to know we’re on track to develop a game that shows promise at improving on current educational training.”
For the study, Mohan recruited 368 physicians from across the US who did not work at hospitals specialising in severe trauma. Half were assigned to play the game and half were asked to spend at least an hour reading the educational materials.
Participants then responded to questionnaires and completed a simulation that tested how often they “under-triaged,” or failed to send severe trauma patients to hospitals with the resources necessary to handle them.
Physicians who played the game under-triaged 53% of the time, compared with 64% for those who read the educational materials.
Six months later, Mohan reassessed the physicians and found that the effect of the game persisted, with those who played the game under-triaging 57% of the time, compared to 74% for those who had read the educational materials.
