Evaluation of a newly developed media-supported 4-step approach for basic life support training

After baseline testing, 220 laypersons were either trained using the widely accepted method for resuscitation training (4-step approach) or using a newly created “media-supported 4-step approach”, both of equal duration. In this approach, steps 1 and 2 were ensured via a standardised self-produced podcast, which included all of the information regarding the BLS algorithm and resuscitation skills. Participants were tested on manikins in the same mock cardiac arrest single-rescuer scenario prior to intervention, after one week and after six months with respect to ECC-performance, and participants were surveyed about the approach.Participants (age 23？±？11, 69% female) reached comparable practical ECC performances in both groups, with no statistical difference. Even after six months, there was no difference detected in the quality of the initial assessment algorithm or delay concerning initiation of CPR. Overall, at least 99% of the intervention group (n？=？99; mean 1.5？±？0.8; 6-point Likert scale: 1？=？completely agree, 6？=？completely disagree) agreed that the video provided an adequate introduction to BLS skills.The “media-supported 4-step approach” leads to comparable practical ECC-performance compared to standard teaching, even with respect to retention of skills. Therefore, this approach could be useful in special educational settings where, for example, instructors’ resources are sparse or large-group sessions have to be prepared.Within cardiopulmonary resuscitation (CPR), external chest compressions (ECC) are the key element providing forward blood flow, thereby maintaining heart and brain viability. Thus, ECC are of primary importance for improving outcomes after in- or out-of-hospital cardiac arrest.Existing data about the ideal training methods for basic life support (BLS) are still insufficient; the duration of BLS training that is adequate remains unknown. Pedagogic training methods are thought to be the best, but specific auxiliary training methods that would
