Clinical evidence supports the concept that expeditious response is a key component of Quality Medical Care.

EAS is contractually required to monitor response time performance for Code 2 and Code 3 emergency calls in two Exclusive Operating Areas (EOAs) managed by the County of Orange.  We have daily reporting requirements that specify on time responses of 90% in both categories, with 14 minutes 59 seconds being the standard for Code 2 (or Urgent – Non Red Lights and Siren) runs and 9 minutes 59 seconds being the standard for Code 3 (or Red Lights and Siren) responses.  Indicators for response time performance are set by contract. The indicators are monitored using our Computer Assisted Dispatch (CAD) system daily, weekly, monthly and quarterly.

The intent of the indicators is to ensure contract requirements are being consistently met and that the public is being adequately served.  Persons interested in our 911 response time compliance can access information at the following link: http://healthdisasteroc.org/ems/aps
