Introduction

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.

Methods

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.

Results

One hundred and seventeen participants were assessed (three drop-outs). The proportion of students achieving a mean compression depth 40–50 mm 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.

Conclusions

Compression skills acquired in a SL station combining video-instruction with training using voice feedback were not inferior to IL training.
