Adherence to the ABCDE approach in relation to the method of instruction: a randomized controlled simulation study

Background The Airway, Breathing, Circulation, Disability, and Exposure (ABCDE) approach is widely recommended and taught in many resuscitation courses. This study assessed the adherence to the ABCDE algorithm and whether this was affected by the instruction method used to teach this approach. Methods Randomized controlled trial in which simulation was used as investigational method. Between June 2017 and January 2018, neonatal healthcare providers routinely participated in simulated neonatal advanced life support (NALS) scenarios, using a high-fidelity manikin. They were randomly assigned to a video-based instruction (intervention group) or a conventional lecture (control group) as the method of instruction. One blinded researcher evaluated the adherence to the ABCDE approach on video with an assessment tool specifically designed and tested for this study. The primary outcomes were: 1) the overall adherence and 2) the between-group difference in individual adherence to the ABCDE approach, both expressed as a percentage score. Secondary outcomes were: 1) the scores of each profession category (nurses, neonatal ward clinicians, fellows/neonatologists) and 2) the scores for the separate domains (A, B, C, D, and E) of the algorithm. Results Seventy-two participants were assessed. Overall mean (SD) percentage score (i.e. overall adherence) was 31.5% (19.0). The video-based instruction group (28 participants) adhered better to the ABCDE approach than the lecture group (44 participants), with mean (SD) scores of 38.8% (18.7) and 27.8% (18.2), respectively ( p = 0.026). The difference in adherence between both groups could mainly be attributed to differences in the adherence to domain B ( p = 0.023) and C ( p = 0.007). Neonatal ward clinicians (39.9% (18.2)) showed better adherence than nurses (25.0% (15.2)), independent of the study group ( p = 0.010). Conclusions Overall adherence to the ABCDE algorithm was rather low. Video-based instruction resulted in better adherence to the ABCDE approach during NALS training than lecturing.
