[Accesibility and effectivity in Mexico]

This is an analysis of two of the dimensions of a health system: accessibility and effectiveness, taking account the objectives of a health system (improving the health of the population, provide appropriate treatment for users of health services and ensure financial security for health) cannot be achieved exclusively by a well-functioning health system and the provision of medical services, being that the health status is explained by many factors and social determinants that deal with the conditions of people and their health behaviors and the level of individual co-responsibility. Despite the advances in the Mexican health system which has greatly improved the health conditions of the population, there is a lag in investment in health, with the major investment challenges as such, coordination between all levels, distribution of human, technological and financial resources, the autonomy of professional practice, the innovation of attention schemes, and modernization of trade unions.
