Comprehensive Assessment of Emergency Medical Services 118 <br />and 911 /Communications Center Operations Study <br />The average annual Call Answer -to -Call Termination times ranged from a low of 01:38 (98 seconds) in <br />2011 to a high of 01:44 (104 seconds) during 2010. <br />Keep in mind; however, this is telephone Call Answer -to -Call Termination time with the 911 caller. It is <br />not the Call Answer -to- Dispatch time referenced for which time interval standards have been <br />established. Emergency response agencies are dispatched via radio, not by telephone. Subsequently as <br />is often the case, the Telecom municator may in fact dispatch the response agency while on the phone <br />with the caller before, or sometimes well before, they terminate the conversation with the caller; in <br />which case the call answer -to- dispatch time may be less than the Call Answer -to -Call Termination time; <br />which then might suggest that the Call Answer -to- Dispatch interval objectives suggested were achieved. <br />Figure 47 <br />Call Answer -to -Call Dispatch Call Answer -to- Dispatch Times <br />The sub - section that follows briefly addresses the data issues <br />encountered during the conduct of this study. Despite repeated <br />efforts by Emergency Services personnel, this specific time interval <br />(Call Answer -to- Dispatch) proved the most elusive in terms of the <br />data available and its reliability; i.e. lack of reliability.

Many hours of monitoring <br />Communications Center activity via radio and in the Center itself has demonstrated repeatedly that 911 <br />calls ore being dispatched in far less than the 2 -3 minutes indicated in Figure 47. Considering the <br />County's recent approval to purchase new CAD system software, and its (hopefully) expedient arrival <br />and installation, it was determined that further efforts by staff to assess this issue would be non- <br />productive. <br />The Data <br />The availability of and accessibility to useable data from the Communications Centers CAD system was a <br />concern expressed from the very outset of this study by the County itself. <br />Typically a jurisdiction's 911 Center's Computer Aided Dispatch (CAD) data base serves as the <br />foundation of useable emergency call and response data for any and all emergency service agencies, <br />and system managers and is the basis upon which they base performance assessments, resource <br />deployment, staffing, and budget decisions. The data must be easily accessible, up to date, user <br />(especially service agency) friendly, and its accuracy; i.e. reliability; assured. <br />This was not found to be the case in Orange County. Why? For one, the CAD system currently in place <br />was originally purchased and installed in 1992. Many "patches" and "parts" have reportedly been <br />added since that time. The fact remains that the technology used for collecting and analyzing <br />emergency services call and incident response data is twenty (20) years old! <br />While Emergency Services staff labored repeatedly to access, reformat if necessary, interpret and make <br />countless runs of data fields to get to the information required for this study, the efforts should not have <br />had to take the time it did had the system been even modestly up to date. <br />Solutions for Local Government, Inc. 74 <br />
