There are approximately 292,000 adult in-hospital cardiac arrests in the United States annually, and survival rates remain low.1 Team leadership skills have been identified as a key area of focus for improving cardiac arrest outcomes, but these same guidelines do not define who the team leader should be.2,3 In current practice, the code team leader is often the health care professional with the most credentials, but outcomes based on this tradition had not been studied previously. In this issue of Mayo Clinic Proceedings: Innovations, Quality & Outcomes, Hejjaji et al4 report their study on the survival outcomes of adult patients with in-hospital cardiac arrest (IHCA) across hospital groups based on the credentials of the resuscitation team leader.
