Combining video instruction followed by voice feedback in a self-learning station for acquisition of Basic Life Support skills: A randomised non-inferiority trial

Teaching basic life support with an automated external defibrillator using the two-stage or the four-stage teaching technique

“…On the basis of a previous study, a 20% noninferiority margin was prespecified [23]. A 20% noninferiority margin may be questioned and after designing and determining the noninferiority margin of 20% in this study, other studies have been published using a noninferiority margin of 10% [28,29]. Using a noninferiority margin of 10% in the present study, the two-stage teaching technique would not have been statistically different (i.e.…”

Part 14: Education

“…50, Evidence on the effect of feedback devices on CPR skill retention is limited, with 1 of 3 studies demonstrating improved retention. 82,85,86 Use of feedback devices can be effective in improving CPR performance during training (Class IIa, LOE A).…”

Part 8: Education, Implementation, and Teams

“…50,191,192,211,214 Meta-analysis was not possible. For the important outcome of skill performance at course conclusion, we found 28 low-quality studies (downgraded for risk of bias, imprecision, and indirectness) that demonstrated some limited improvement in CPR quality.…”

“…Heterogeneous reporting prevented some meta-analyses. There were 23 directive feedback studies 50,[191][192][193][194][195][196][197][198][199][200][201][202][203][204][205][206][207][212][213][214][215][216] showing that in comparison with no feedback devices, the use of feedback devices…”
