EMS Duty Officer

What is the EMS Duty Officer Program?

The County of San Diego Emergency Medical Services (EMS) Duty Officer is available 24 hours a day/seven days a week to respond to mutual aid requests, coordinate disaster medical operations, and to assist hospitals and providers in managing the EMS system.


When should the County EMS Duty Officer be contacted?

Duty Officer requests are divided into Notifications, Urgent Alerts, and Regional Emergencies.

EMS Duty Officer notifications are expected from System participants when an incident, event or exercise has the potential to cause EMS Delivery System impact. The EMS Delivery System includes EMS and Emergency Departments equally. When in doubt, notify the EMS Duty Officer.

Notifications (Level 3) include:

  • Offload delays as defined in County EMS Policy S-610
  • Hospital bed counts
  • Failures or significant trouble with EMS communication or data systems
  • Significant incidents where media interest may extend to the EMS Delivery System (e.g., expanded incidents, multiple fatalities, disruption of the larger EMS Delivery System)
  • Large planned or no-notice mass gatherings to which EMS resources could potentially be assigned (e.g., peaceful demonstrations, civil unrest)
  • Unusual but urgent events that require County EMS notification (e.g., non-injury vehicle accidents where an ambulance is involved and disabled)

Urgent Alerts (Level 2) include:

  • Any incident resulting in a temporary or prolonged reduction in first responder medical response coverage
  • Death or serious line-of-duty injury of EMS system personnel
  • Ambulance provider (ALS, BLS, or CCT) declaring service disruption or inability to provide 24/7 service
  • Anticipated prolonged ambulance diversion as defined in County EMS Policy S-010
  • Prehospital events with the potential to impact the larger EMS Delivery System (e.g., prison riot, multi-patient collisions with many patients requiring transport)
  • Incidents, events or other disruptions that need to be communicated to the larger EMS Delivery System (e.g., law enforcement closures or impact, HazMat incidents affecting EMS routing)
  • Hospitals declaring Internal Disaster or other critical issues
  • Calls with requests or notifications from another County (including XSD MHOAC requests/notifications)

Regional Emergencies (Level 1) include:

  • Immediate safety alerts, such as a violent individual in the emergency department or hospital parking lot requiring incoming ambulance traffic to be urgently rerouted
  • Annex D/Mass Casualty Incident alert or activation
  • Annex D/Mass Casualty where 3 or more patients will be transported out of the county
  • Request for significant additional resources from another zone or county
  • BioWatch or other environmental sampling results/alerts
  • Surge transportation, actual or planned need (e.g., medical facility evacuation requiring the equivalent of more than one Ambulance Strike Team)
  • Prolonged (> 1 hour) “Level Zero” status in an EMS Operational Area
  • Activation of the County Emergency Operations Center (EOC)
  • Alert or activation of the County of San Diego HHSA Department Operations Center/Medical Operations Center (DOC/MOC)

When in doubt, notify the Duty Officer.

Be prepared to provide the EMS Duty Officer dispatch center with:

  • information on the urgency of the request as per the information above
  • whether a callback is needed and time frame
  • what your specific request is (or notification only)
  • location of the incident (if applicable)
  • your contact info, agency, and title/role
