Comprehensive Assessment of Emergency Medical Services 16 <br /> DRAFT REPORT and 911/Communications Center Operations Study <br /> Call Volume <br /> During calendar year 2011, Orange County EMS units were dispatched a total of 10,719 times. In <br /> addition to these incidents, Medic Units were ordered into "move-up" status 2,360 times. <br /> Figure 6 <br /> EMS Annual Call Volume <br /> od <br /> 11,000 .. m ii 10,719 ', <br /> 10,420 <br /> 10,500 1111...... ; <br /> Joi <br /> 10,000 9,833.... <br /> 9 <br /> Jod <br /> ,14' , ,. <br /> Jod <br /> od <br /> od <br /> � t <br /> 9,500 9,269 n 1111... rr ........ od <br /> Jod <br /> Jod <br /> 9,000 ........ ........ <br /> 1111.,... <br /> Jod <br /> Jod <br /> 2007 'i 2008 2009 ! 2010 2011 <br /> "Move-ups" occur when the number of ambulances available to respond to a call is down to one (1) <br /> ambulance and that ambulance, regardless of where it is normally assigned, will be directed to "move- <br /> up" to a location generally towards the center of the County to be accessible to respond in any <br /> direction. <br /> If there comes a point that "no" ambulances are available (which does occur) South Orange Rescue <br /> and/or one or more of the County Fire Departments will be alerted to stand-by or, if available, to <br /> "move-up"to a specific staging location. <br /> It is a practice common in the industry often referred to as "modified system status management" as it <br /> provides a means of spreading thin resources strategically in an effort to provide the greatest range of <br /> coverage during peak call periods. <br /> Type of Call <br /> The type of calls to which EMS is dispatched will of course vary. A review of those calls dispatched <br /> during 2011 identified more than twenty call classifications. Of the 10,719 calls dispatched during 2011, <br /> almost 90 percent were listed in one of the 18 categories identified in Figure 7 i.e. as noted, any call type <br /> representing more than one percent of the total. <br /> And, while they are not emergency dispatches per se, 2,360 "move-ups" were directed for strategic <br /> purposes; primarily to enhance coverage when the number of available ambulances to respond to an <br /> emergency was down to one (1). While the NCOEMS and the Performance Improvement Center <br /> recommend that any EMS Unit activity be recorded in PreMIS in order that unit hour utilization rates can <br /> be (eventually) accurately determined, they are not included in this table or in the previous Call Volume <br /> table as emergency dispatches. <br /> Solutions for Local Government,Inc. 14 <br />
