Emergency Preparedness and Response

Medical Health Operational Area Coordinator Program

To manage the complex needs and requirements of an emergency response effort, the El Dorado County (EDC) Health and Human Services Agency’s (HHSA) Emergency Medical Services Agency (EMS) and Public Health Preparedness and Response (PHPR) oversee the EDC Medical Health Operational Area Coordination (MHOAC) Program.

The EDC MHOAC Program maintains a 24/7/365 capability to:

  • Initiate emergency notifications;
  • Coordinate requests for medical health assistance and/or resources; and
  • Obtain and distribute information to enhance situational awareness.

EMS and PHPR staff the EDC MHOAC Program through a MHOAC Duty Officer. During emergencies, serious accidents, or impending or actual events, the MHOAC Duty Officer provides:

  • A single entry point for local, operational area, regional and state agencies
  • Serves as the liaison between HHSA, the Emergency Operations Center (EOC) and healthcare facilities.
  • Implements medical and health response plans
  • Collects and disseminates information to essential stakeholders and response partners, and
  • Achieves objectives in support of the Department and Emergency Operations Centers’ missions

The EDC MHOAC Program will apply the principles and concepts of the Incident Command System (ICS), Standardized Emergency Management System (SEMS), and the National Incident Management System (NIMS). MHOAC activities will also be conducted in accordance with the California Public Health and Medical Emergency Operations Manual (EOM).
