Background: Teamwork is critical for patient and provider safety in high-stakes environments, including the setting of prehospital emergency medical services (EMS).
Objective: We sought to describe the components of team leadership and team membership on a single patient call where multiple EMS providers are present.
Methods: We conducted a two-day focus group with nine subject matter experts in crew resource management (CRM) and EMS using a structured nominal group technique (NGT).
