Abstract
BackgroundMany barriers exist to the wider and sustainable implementation of basic life support (BLS) training in secondary schools. Whether trained teacher instructors are not worse than healthcare instructors by 20% (noninferiority margin) of simulated BLS skills for secondary school students is unclear. MethodsWe conducted a two-armed, parallel, noninferiority, blinded, randomized controlled trial at four secondary schools in Hong Kong after teachers had undergone BLS training. Students were randomized to either the trained teacher or healthcare instructor group for the 2-hour compression-only cardiopulmonary resuscitation and automated external defibrillator (CO-CPRAED) course. The assessors for the students’ BLS skill performance six months after the CO-CPRAED course were blinded. ResultsOf the 33 trained teachers, 13 (39.4%) volunteered to be instructors for the CO-CPRAED course. Three hundred and eleven students (median age: 15 years, 67% males) were randomized to either the teacher (n = 161) or healthcare (n = 150) instructor group. The BLS skill performance passing rate (%) at six months was high in both instructor groups (teacher: 88% versus healthcare: 91%; mean difference: −3%, 95% CI: −11% to 5%; P = 0.22). The students’ knowledge levels remained high (>90%) and were similar between instructor groups at six months (P = 0.91). The teachers’ willingness to teach BLS to students was mildly positive. However, the students were extremely positive towards learning and performing BLS. ConclusionsA brief 2-hour CO-CPRAED intervention by trained teachers was noninferior to healthcare instructors and it was associated with students’ very positive attitudes towards CPR, and retention of knowledge and BLS skills.
