MedStar is a high performance Emergency Medical Services (HPEMS) system, providing advanced clinical care with high economic efficiency. 

High Performance EMS systems share key features of system design rarely associated with less cost-effective systems:

Sole provider: Exclusive market rights to provide emergency and non-emergency ambulance service are granted to a sole, and often competitively selected, provider.

Control center operations: The ambulance provider has control of the dispatch center.

Accountability: HPEMS systems have performance requirements that can result in financial penalties or replacement of the provider when not met. HPEMS systems regularly collect and use data to meet these performance requirements.

Revenue maximization: HPEMS systems incorporate the business function into their operations, resulting in a better understanding of the billing requirements and maximization of revenues from Medicare, Medicaid, and other third-party payers.

Flexible production strategy: HPEMS systems employ a single fleet of Advanced Life Support units capable of handling any type of service request, resulting in all patients receiving the highest level of care and higher productivity levels.

System Status Management (SSM): HPEMS systems use the flexible deployment technique, SSM, to move ambulances in anticipation of where that ambulance will be needed.
