Training approaches for the deployment of a mechanical chest compression device : a randomised controlled manikin study

Objectives: To evaluate the effect of training strategy on team deployment of a mechanical chest compression device. Design: Randomised controlled manikin trial. Setting: Large teaching hospital in the UK Participants: Twenty teams, each comprising three clinicians. Participating individuals were health professionals with intermediate or advanced resuscitation training. Interventions: Teams were randomised in a 1:1 ratio to receive either standard mechanical chest compression device training or pit-crew device training. Training interventions lasted up to one hour. Performance was measured immediately after training in a standardised simulated cardiac arrest scenario in which teams were required to deploy a mechanical chest compression device. Primary and secondary outcome measures: Primary outcome was chest compression flow-fraction in the minute preceding the first mechanical chest compression. Secondary outcomes included cardiopulmonary resuscitation quality and mechanical device deployment metrics, and non-technical skill performance. Outcomes were assessed using video recordings of the test scenario. Results: In relation to the primary outcome of chest compression flow-fraction in the minute preceding the first mechanical chest compression, we found that pit-crew training was not superior to standard training (0.76 (95% CI 0.73 to 0.79) v 0.77 (95% CI 0.73 to 0.82), Mean difference -0.01 (95% CI -0.06 to 0.03), p=0.572). There was also no difference between groups in performance in relation to any secondary outcome
