From spectator to lifesaver: a six-month evaluation of bystander training in CPR and bleeding control[1]

Summary

Prospective before/after evaluation of a national bystander CPR-and-bleeding-control training initiative at a South Asian LMIC institution: 200 adult non-medical staff assessed pre-training (T1), immediately post (T2) and at six months (T3). 89% had no prior training. Knowledge and self-efficacy rose significantly for both skills from T1 to T2 and remained above baseline at T3 (all p<0.001), independent of educational status - but both measures declined from T2 to T3, evidencing skill/confidence decay and the need for refreshers. Confidence rose short- and long-term, with a notable fall in fears about injuring the victim or being sued. The authors recommend biannual refreshers, policy-level bystander (Good Samaritan) protection, and education-agnostic delivery.

So what

The evidence base for treating spectators and event staff as the first defibrillation/haemorrhage-control layer - the human counterpart to a dense AED network. Two findings port straight into event planning: training works regardless of education level (so mass, non-selective staff/volunteer training is justified), but confidence and knowledge decay by six months (so a single pre-season induction is not enough - schedule biannual refreshers). The measured drop in fear of litigation/harm is the barrier an event's Good-Samaritan messaging can target. Pairs with the noise page's social-intervention logic (behaviour change via normalization) and the crowd-crush page's bystander theme; strengthens the cardiac-arrest/AED shelf on the human-factors side. LMIC single-site, so cite for the training-effect and decay curve, not absolute rates.

Key findings

  • 200 non-medical adults, LMIC; 89% no prior CPR/bleeding-control training
  • Knowledge + self-efficacy up T1->T2 and T1->T3 (all p<0.001), independent of education level
  • Decay T2->T3 = need for biannual refresher training
  • Fear of injuring victim / being sued fell notably — the trainable barrier
  • Supports mass, education-agnostic bystander training as the first responder layer; free PMC
