In Mexico, pharmacies have the possibility of offering basic health services inside or close to their facilities. The foregoing generates direct competition for non-profit civil associations such as the Mexican Red Cross (MRC) in Monterrey, which currently has nine urban health facilities. As it is well known, the Red Cross is maintained through donations, and for the services provided, a voluntary fee is asked.  Due to the recent financial losses, and looking for increasing the productivity of its health care facilities, the MRC is considering the closure of some of them with a minimal social impact due to the decrease of the community’s access to health services.

In this work, we propose a framework for measuring the social impact of closuring MRC health facilities.  The closure’ impact of urban health facilities has not been deeply explored. After a bibliographic review, fifteen variables related to social impact were identified, which were grouped into three categories: competition, organization and affected population. This paper proposes an optimization model with the variables investigated and adapted to the urban context to determine which facilities should be closed with the least social impact and significantly increase of the MRC’s average productivity.
