GIS served ambulance arrival time in the Kvemo Kartli region, Georgia

We aimed to estimate the arrival time of the ambulance based on a GIS in Kvemo Kartli, one of the regions of Georgia, analyze contextual factors that affect this time, and support defining the target response time standards in the region and country. For this purpose, the isochrone map of ambulance travel time intervals to patients was created based on GIS, taking into account the location of the emergency bases, settlements, the length of the roads, and data on the maximum permitted speeds of the vehicle, based on which it is estimated what percentage of the population will and will not be reached by ambulance in the different time intervals. The results show that in the underserved areas where the ambulance cannot reach the patients, within 8 minutes lives 52 percent of the population of Kvemo Kartli, which is almost 222,976 people. Thus, the 8-minute reachability area of an ambulance should be expanded, and it is also necessary to define response time standards in the Kvemo Kartli region, Georgia. These actions will enhance the quality of emergency medical services and benefit the population.
