Abstract
Current computerised self-learning (SL) stations for Basic Life Support (BLS) are an alternative to instructor-led (IL) refresher training but are not intended for initial skill acquisition. We developed a SL station for initial skill acquisition and evaluated its efficacy.In a non-inferiority trial, 120 pharmacy students were randomised to IL small group training or individual training in a SL station. In the IL group, instructors demonstrated the skills and provided feedback. In the SL group a shortened Mini Anne™ video, to acquire the skills, was followed by Resusci Anne Skills Station™ software (both Laerdal, Norway) with voice feedback for further refinement. Testing was performed individually, respecting a seven week interval after training for every student.One hundred and seventeen participants were assessed (three drop-outs). The proportion of students achieving a mean compression depth 40-50mm was 24/56 (43%) IL vs. 31/61 (51%) SL and 39/56 (70%) IL vs. 48/61 (79%) SL for a mean compression depth ≥ 40 mm. Compression rate 80-120/min was achieved in 49/56 (88%) IL vs. 57/61 (93%) SL and any incomplete release (≥ 5 mm) was observed in 31/56 (55%) IL and 35/61 (57%) SL. Adequate mean ventilation volume (400-1000 ml) was achieved in 29/56 (52%) IL vs. 36/61 (59%) SL. Non-inferiority was confirmed for depth and although inconclusive, other areas came close to demonstrate it.Compression skills acquired in a SL station combining video-instruction with training using voice feedback were not inferior to IL training.
