Comprehensive Assessment of Emergency Medical Services 58 <br /> DRAFT REPORT and 911/Communications Center Operations Study <br /> The methodologies used to project future needs;whether people,workload, or in this instance EMS call <br /> volume; will typically involve an examination of recent year trends of those same characteristics. Today <br /> of course the application of technology and various software programs are available as well;all of which <br /> also, however,will typically require historical data to feed their formulas. <br /> Subsequently, the starting point for these calculations will be the experienced (known) annual EMS call <br /> volumes for 2000-2011 and noted in Figure 31, together with the annual County populations as <br /> documented by the North Carolina Office of Budget& Management for the same years. <br /> Between 2000(116,106)and 2011(135,776)the County's population increased 16.9 percent. <br /> Between 2000(9,231)and 2011(10,719)the County's annual EMS call volume increased 16.1 percent. <br /> While the County's total annual population figures are important, the correlation of the number of EMS <br /> calls per unit of population served; in this case the number of calls per 1,000 residents; is the variable <br /> that will be incorporated into the calculations of future annual EMS call volumes; Figure 34. <br /> As illustrated in Figure 33 the number of EMS calls per 1,000 residents of course varied from year-to- <br /> year; in this case, the ratio increased during eight (8) different years and decreased during three (3) <br /> different years. In this case the average annual change in the EMS calls/1,000 ratio was+3/10ths of 1%. <br /> Figure 33 <br /> Projected Annual EMS Calls/1,000 County Population/2012-2032 <br /> 88 — <br /> 1 1 I <br /> 86 86 <br /> 85 84 -8A-85" <br /> 838'484 <br /> 84 Y____J_1_1_L__J_J_1_L_L____J_J_ _L____J L&3.
