Abstract 14348: Retention of CPR Skills in High School Students Following a 45-minute Instructor-led Course With Hands-on Practice: A Cross-sectional Analysis
Introduction: Currently, 32 states require CPR training for high school students; it is unknown whether real-world training leads to skill retention. The purpose of this study was to evaluate longitudinal CPR skill retention in an unprecedentedly large cohort of students.
Hypothesis: We hypothesized that both CPR knowledge and skill retention would decay with time.
Methods: Seven-hundred and ninety-five students participated in a 45-minute hands-only CPR course which included theoretical background, instructor demonstration, and hands-on practice. CPR quality was not recorded during initial training. Two groups of students were then tested simultaneously; those who had received training 3 months prior (n = 431) and 6 months prior (n = 364). CPR knowledge was assessed with a questionnaire, and skills were recorded including chest compression (CC) rate and percentage of CC at appropriate depth.
Results: CPR skill retention was poor in both groups. The percentage of students that performed CC at appropriate rate of 100 to 120 per min was 35% (n= 148 of 425) in the 3-month (3-mo) group vs. 33% (n= 118 of 361) in the 6-month (6-mo) group (p=0.4770). The percentage of students achieving appropriate depth at least 70% of the time was 38% (3-mo, n= 162 of 425) vs. 30% (6-mo, n= 108 of 358) (p=0.4194). CPR knowledge was superior to skill demonstration. The percentage of students correctly identifying appropriate rate was 47% (3-mo, n= 199 of 425) vs. 43% (6-mo, n= 156 of 361) (p=0.3108). The percentage of students correctly identifying appropriate depth was 80% (3-mo, n= 338 of 422) vs. 69% (6-mo, n= 249 of 361) (p=0.0119).
Conclusions: In this large cohort of high school students, both CPR knowledge and skill retention were poor following a real-world 45-min CPR course, but only one knowledge item showed significant decay over time. CPR knowledge was superior to skill demonstration. This study highlights the need to develop CPR training methods that lead to longitudinal skill retention.
