What this specialty covers

An emergency physician focuses on the immediate decision making and action necessary to prevent death or any further disability both in the pre-hospital setting by directing emergency medical technicians and in the emergency department. The emergency physician provides immediate recognition, evaluation, care, stabilization and disposition of a generally diversified population of adult and pediatric patients in response to acute illness and injury.

Reading the sole-proprietor share

For this specialty, the sole-proprietor share is an administrative description of NPI records, not a direct count of emergency physicians working in private practice. The flag is a self-reported NPPES field and an imperfect proxy because emergency physicians may practice through hospitals, physician groups, staffing organizations, or other arrangements.
