Identifying inequity in gaining access to and financing health service attention in Bogotá.The 2003 Quality of Life and Health Survey for Bogotá was analysed. Socioeconomic, needs, access to health services and financing them were identified as variables. A descriptive and bivariate analysis was done, variables were re-codified and scenarios were created combining variables regarding needs, access and financing attention.18,4 % of the population in the contributory regimen and 26,8 % of the subsidized regime were not gaining access to health services. The main barrier to gaining access for using health services is the lack of money, even in the population affiliated to the social health security system (SHSS). The localities presenting the greatest inequity in access to health services were San Cristóbal, Kennedy and Rafael Uribe. Two profiles were configured from the scenarios so constructed: that having greatest inequity (determined by belonging to the 1st and 2nd quintiles, being male, being aged 0-18 years old, being in the subsidized regimen or not being affiliated to the SHSS) and that offering the best conditions of equity (related to being female, aged over 19, belonging to the 3rd, 4th or 5th quintiles and being affiliated to the contributory regimen).Inequity in gaining access to health services was observed, particularly in the poorest population, even though being affiliated to the SHSS.
