Obstetric Life Support Education for Maternal Cardiac Arrest - A Randomized Clinical Trial
Management of maternal cardiac arrest (MCA) requires understanding the unique physiology of pregnancy and modifications to life support. Health care professionals have historically demonstrated inadequate knowledge and skills necessary to treat MCA.
Current training tools for MCA are insufficient and lack performance assessment features. Obstetric Life Support (OBLS) is a comprehensive training program designed to address this gap by equipping health care professionals with the knowledge and skills to manage MCA effectively, including performance assessments for individuals and teams. This study evaluates the effect of OBLS training on cognitive performance, self-efficacy, megacode evaluations (observations of participant technical resuscitation and behavioral team leadership skills during an MCA scenario),
and combined assessment pass rates among health care professionals in prehospital and in-hospital environments.
In this randomized clinical trial, OBLS education significantly improved health care professionals’ knowledge, skills, and confidence in managing MCA. These findings underscore the urgent need for implementation of a standardized MCA curriculum nationwide, especially as the US continues to face unacceptably high maternal mortality rates.
