Our Mission:

The Area Metropolitan Ambulance Authority was established in 1986. For nearly 20 years, MedStar contracted with private-for-profit contractors to provide day-to-day operational management through competitive-based contracting. The Authority administered the contract, managed accounts receivable, and managed the system infrastructure including the primary facilities and communications center. In the spring of 2005, the Authority negotiated an end to the contract with its most recent contractor.  The Authority then assumed all responisbility for the day-to-day operations of the EMS system and created the MedStar we know today.


System Management

From the patient’s perspective, when calling 9-1-1 for an ambulance they want it to arrive quickly and render aid that provides relief. MedStar's priority is to ensure that requests for service are handled promptly and ambulances reliably respond to any call.     


MedStar utilizes state-of-the-art System Status Management, which allows us to effectively cover our geographic service area while adjusting the location and number of ambulances in service to compensate for the ebbs and flow of call demand.  We use a sophisticated predictive modeling system that graphically displays areas of projected call volume in 5 minute slices.  We then move ambulances throughout the service area to cover the predicted demand.


Our system offers all Advanced Life Support services (ALS) and Mobile Intensive Care Units (MICU). With all ALS, the patient receives the highest level of care available upon arrival of the first responding ambulance. Further, this “single-tier” system has proven to be the most cost-effective and cost-efficient system found in EMS today.
