911 Call Volume and Response
Target: 90 percent of calls answered within 10 seconds
Status: NOT MEETING TARGET
Result: 74 percent of calls answered within 10 seconds
When someone calls 9-1-1 to report an emergency, he or she expects a prompt answer from someone who can initiate the chain of assistance for the emergency. This measure indicates the percent of 911 calls answered within 10 seconds. The industry standard established by the National Emergency Number Association (NENA) is that 90 percent of all emergency calls should be answered within 10 seconds.
9-1-1 CALL VOLUME AND RESPONSE RATE
How the Department of Emergency Management is Performing
Total call volume, comprised of emergency and non-emergency calls, began to increase in September 2011 and continued to grow at a rapid rate through 2017. After roughly five years of call volume growth, service levels decreased below the goal of 90 percent of calls answered within 10 seconds.
Through San Francisco’s Civic Bridge program, a team from Google worked collaboratively with Department of Emergency Management (DEM) to investigate factors behind, and make recommendations to address, the City’s 911 call volume increase. The resulting paper, released October 2015, indicates that an increase in multiple 911 calls for the same incident, accidental cellphone dials to 911, and an increase in police-reported incidents are factors in the 911 call volume increase, as well as the comparable increase in non-emergency calls. Recommendations to address these issues include improvements to computer-aided dispatch (CAD) system functionality such as automatically capturing a “source” field for all CAD incidents, automating the callback process for dispatchers, and tracking accidental dials with a new CAD code.
Most significantly, the Department is undertaking a major hiring campaign to address the increased workload and replace recent higher-than average levels of retirements. The job is both very sensitive and highly skilled, requiring six to ten months of background checks to be completed before a hire is made and nine months of training before a new employee is cleared to do emergency call-taking and dispatch work.
How Performance is Measured
The call-taking time interval is measured from the time a 911 call arrives at the Public Safety Answering Point (PSAP) until a dispatcher answers the call. Average daily 911 call volume is calculated by summing the number of 911 calls received in a month and dividing by the number of days in that month.
