Physician extension brings physician-directed care to the patient's side through EMERGILITY® EMS providers and practitioners, under the direction of our Operational Medical Director.
Physician extension occurs when a physician authorizes a non-physician to deliver medical care on the physician's behalf. In traditional practices, the physician extender is a nurse practitioner (NP) or physician assistant (PA) working under a collaborative practice agreement.
In EMS, physician extension happens through a licensed EMS agency. Certified EMS providers deliver care under the agency's Operational Medical Director (OMD), standing orders, and protocols. In Virginia, as in most states, a physician's license alone cannot authorize EMS care outside a licensed agency; the agency is what makes it lawful.
EMERGILITY® provides discreet, protective, urgent, and emergency medical services utilizing physicians, physician extenders (advanced practitioners, nurses, and EMS providers), mixed medical-security professionals, and non-medical security personnel. The level and type of provider present is based on client need and resource availability.

Our Operational Medical Director sets the protocols and standing orders we follow.

Our EMS Agency credentials each provider and practitioner to their scope of practice.

Providers deliver physician-directed care at the patient's side, wherever it's needed.

Every patient encounter is reviewed for quality, with physician oversight and feedback.
