Exploration of 'generational' peer-led CPR training in the Australian community using blended learning approaches: a...

A pilot randomised controlled trial to assess the feasibility and relative effectiveness of a community CPR train-the-trainer model using either a traditional face-to-face or blended learning approach (video supported face-to-face training with the provision of a multimodal 'CPR lesson card' containing visual prompts and a QR linked training video). A 'generational' recruitment strategy was used to evaluate knowledge degradation across a series of peer-led training episodes.

Participants (n = 155) were community volunteers aged 18-85 years with no recent CPR training. Groups were randomised to either face-to-face (control) or blended training (intervention) groups. The first participant in each stream (Generation one) received professional training and subsequently taught the next generation, continuing up to four generations. Progression required passing a simulated cardiac arrest assessment against a critical item checklist including a QCPR score ≥50.

In total, 115 CPR assessments were conducted (57 intervention, 58 control) following episodes of intergenerational peer-led training. Pass rates were 96.5 % (55/57, 95 % CI: 87.9-99.6 %) in the intervention group and 75.9 % (44/58, 95 % CI: 62.8-86.1 %) in the control group (Fisher's Exact p ≤ 0.05). The combined pass rate between both groups was 86 %, supporting feasibility of peer-led CPR training.

Peer-to-peer CPR training in the community is feasible through several generations of knowledge transfer. The use of a simple multimodal training aid appears to enhance performance beyond the first generation and may provide a scalable, cost-effective adjunct to traditional CPR training.
