The access and possibility of rapid response to medical emergencies is an issue that, in last decades, has been studied in many areas of research such as urban planning and transportation, as well as with the issue of equity in the provision of this healthcare service. This is true, in particular for middle- and low-income countries subject to non-equitative access to services such as medical emergency attention. In this study, a medical emergency database review is carried out in order to propose a new methodology to assess the coverage of Ambulance Dispatches and Emergency Service Facilities. This is executed using primary information relating to medical emergencies that occurred in the city of Manizales between 2010 and 2015 and secondary data relating to socio-demographic and economic conditions, analyzing their correlation using a GIS (Geographic Information System) application. This research article proposes a methodology for improving the population coverage of Ambulance Dispatches and Emergency Service Facilities, trying to reduce health inequity in terms of assistance to medical emergencies. Our results show that in order to reduce social and health inequity, the city of Manizales needs to improve its provision of emergency care attention, based on urban planning tools especially in low-income neighborhoods.
