Improving cardiopulmonary resuscitation skills retention: effect of two checklists designed to prompt correct...

Previous research has shown that regardless of an individual's experience, life support skills such as cardiopulmonary resuscitation (CPR) are poorly performed as soon as 1 month following training. The purpose of this study was to compare the effects of two checklists designed to prompt correct CPR performance. We compared the performance of 169 undergraduate students, at the time of course assessment, with retention testing that occurred 2 months following the course assessment. Students were randomly assigned to a control group, a short version of a CPR checklist and a longer more detailed version. Two groups of variables were created: procedural and compression-ventilation variables. In addition, an overall-performance variable was created, summarizing performance on the procedural variables. Binary variables were assessed with chi 2-tests of independence. One-way ANOVAs, using 'group' as the between-subjects factor, were used to assess each continuous variable. Comparisons between groups yielded significant differences of P < 0.05. The long checklist generally led to superior performance on the procedural variables. The results support the hypothesis that remembering the steps of CPR is too complex for some. Though preliminary, the findings of this study indicate that the detailed checklist was an effective strategy to improve the post-course performance of CPR.
