Background: Just-in-time (JIT) video training has been proposed as an alternative to in-person CPR courses, with associated time and cost savings.

Research Question: Does a JIT training video improve layperson performance of CPR?

Aim: Measure CPR performance using a JIT video compared to the American Heart Association (AHA) HeartSaver® CPR AED Training course.

Methods: A convenience sample of laypeople was randomized to perform CPR in a simulated scenario a) after participating in an AHA HeartSaver® course led by experienced instructors, b) with access to a JIT training video, or c) control, with no assistance or training. CPR quality was assessed by trained evaluators and objective performance assessed using Laerdal QCPR-enabled simulators. The primary outcome was performance of correct CPR.

Results: Of 230 eligible subjects, 226 were randomized with no significant differences in baseline characteristics across groups. Prevalence of correct CPR was low, though significantly higher in the AHA group (AHA: 40%, 95%CI 28-51; JIT: 15%, 95%CI 8-26; control 10%, 95%CI 4-19). Overall, 94% of participants performed compressions within 1 minute, with no difference between groups. An AED was called for more frequently in the AHA group (47%) than the JIT (15%) or control (10%) groups. Flow fraction was significantly better in the AHA group (89%, IQR 77-99) compared to the JIT (75%, IQR 47-90) or control (49%, IQR 22-74) groups and compression rates of 100-120 were more frequent in the AHA (51%) and JIT groups (47%) compared to controls (27%).

Conclusions: While correct performance of specific CPR skills varied in this sample, laypersons using a JIT training video performed as well as those taking an AHA HeartSaver® course on several key measures such as rapid chest compression and compression rate. JIT video training may be a viable option for supporting untrained bystander CPR performance, though further evaluation is needed to identify optimal strategies for implementation.
