Nontechnical Skills and Leadership Are Associated With More Efficient Mechanical Cardiopulmonary Resuscitation Deployment in Real-World Cardiac Arrest.

backgroundMechanical cardiopulmonary resuscitation (MCPR) devices provide consistent compressions, yet guidelines discourage routine use partly because deployment can increase no-flow time. Although nontechnical skills improve manual CPR performance, their association with deployment safety during MCPR remains unclear. This study examined the association between nontechnical skills and cumulative no-flow time during MCPR deployment in real-world resuscitations.

methodsWe conducted a prospective observational study of video-recorded cardiac arrest events in a tertiary emergency department. NTS were assessed by trained raters using the Team Emergency Assessment Measure (TEAM). The primary outcome was the association between TEAM scores and cumulative no-flow time during deployment, analyzed with multivariable linear mixed-effects models adjusted for patient characteristics and team leader clustering. Secondary outcomes included MCPR deployment duration and other technical intervals.

resultsEighty-five eligible MCPR cases were analyzed. For each 1-point increase in TEAM global rating, cumulative no-flow time was 6 seconds shorter (95% CI, -10 to -1;

conclusionsHigher nontechnical skills ratings, particularly leadership, were associated with shorter cumulative no-flow time and greater operational efficiency during MCPR deployment. These findings support an association between team nontechnical performance and deployment efficiency in real-world mechanical resuscitation.
