Simulation-based randomized trial of medical emergency cognitive aids

Table 2 Effect of MECA use according to the scenarios (per protocol analysis)

Scenario type	Failure rate†		p-value‡
	With MECA	Without MECA
	n (%)
CPR after MI scenario	113/210 (54%)	221/332 (67%)	0.004
Hemodynamically unstable VT	25/117 (21%)	109/239 (46%)	0.0002
Hyperkalemia-induced asystole	74/168 (44%)	191/302 (63%)	0.00006

Bold values indicate a p-value < 0.05 was considered as statistically significant
MECA medical emergency cognitive aid, CPR cardiopulmonary resuscitation, MI myocardial infarction, VT ventricular tachycardia
^†Failure rate was calculated as the number of critical steps that were not adhered to in the management of the scenario
^‡P values were calculated in a model for clustering by team, scenarios in which the participants used the wrong MECA (e.g. bradycardia instead of asystole) were excluded (Scenario types were as follows: CPR after MI included ventricular fibrillation preceded by myocardial infarction, return-of-spontaneous circulation directly before fourth defibrillation; unstable VT included diagnoses, sedation and cardioversion, and hyperkalemia-induced asystole included bradycardia degenerating into asystole, discussing of potentially reversible causes and treatment of life-threatening hyperkalemia.)
