| Emergency Medical Service (EMS) utilization in the Yonkers, New York was examined in a retrospective study in an attempt to develop a model to predict EMS demand. 1,461 prehospital Patient Care Reports were randomly sampled from years 1990-1993. Across all age groups, males were more likely to utilize EMS than were females, {dollar}chisp2{dollar} (1,1456) = 9.56, {dollar}p < .01{dollar}. Basic Life Support calls accounted for 61.5% of both Basic and Advanced life support calls, {dollar}chisp2{dollar} (1,1391) = 74, {dollar}p < .01{dollar}. Multiple regression analysis showed that the independent variables of Nonwhite Population and Median Household Income accounted for an estimated 55% of variation in the dependent variable Rate of EMS Calls. Future studies of EMS demand in Yonkers should include a larger sample so that the health status of groups of people from different census tracts may be assessed; perhaps leading to interventions that may decrease the rate of EMS utilization. |
