“…Most of the interventions (14) were team-based training 33 , 34 , 35 , 36 , 40 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 but of those, 12 studies included cognitive and/or psychomotor skill practice on individual level. 33 , 34 , 35 , 36 , 40 , 43 , 44 , 45 , 46 , 47 , 49 , 50 Interventions included the traditional instructor-based training; 28 , 33 , 45 , 49 simulation-based mock code program; 34 , 47 , 51 simulation only; 38 simulation with debriefing; 35 , 44 , 48 high-fidelity simulation; 47 feedback of performance; 33 , 43 refresher sessions; 22 , 41 training with real-time feedback; 28 , 37 , 39 , 40 , 41 , 42 , 50 and distributed practice. 44 , 45 , 46 , 49 As some studies used distributed practice as part of their learning strategies prior to retraining interventions, 44 , 45 , 46 , 49 the authors highlighted these studies in the results table ( Table 1 ), as the concept of distributed practice may have a positive effect on performance and retention of skills.…”
