[Assessment of a health program for the non-insured population].
OBJECTIVE: Present the results of the evaluation of a program for the non-insured population of the four poorest states of the country implemented by the Ministry of Health of Mexico between 1991 and 1995. METHODS: The effects of the program were evaluated in three areas: i) increase in health services coverage; ii) delivery of personal health services, and iii) changes in health conditions of the target population. The extension of coverage was measured by the increase in potential access due to the construction of health infrastructure projects and the use of additional health manpower, mainly primary health care workers. For the evaluation of the impact of the program on the delivery of services, three surveys were developed: one for service utilization, another one for accessibility, and a third for quality of care. The impact on health conditions was evaluated by changes in health indicators of children under five and women of reproductive age. RESULTS AND CONCLUSIONS: The Program had a positive impact on coverage, accessibility and quality of services. Its impact on health conditions was also positive. However, these last changes cannot be attributed only to the program, but to the sum of several concurrent activities.
