Pollaris, G. and Sabbe, M. (2016). Reverse Triage: More Than Just Another Method. (Abstract only.) European Journal of Emergency Medicine. 23(4):240-247.
The authors reviewed articles on reverse triage from 2004-2014 and found that, at most, 10-20% of hospital total bed capacity can be made available within a few hours. They note that reverse triage could be a response to Emergency Department (ED) crowding, as it gives priority to ED patients with urgent needs over inpatients who can be discharged with little to no health risks.
