[An approach to the study of health services costs in Mexico]

To approach the cost analysis of the health services for eight tracer conditions, in three institutions of the public sector and in five of the private sector.

First, production functions and inputs required for standard case-management of each tracer condition were identified. Subsequently, tracer case-management was adjusted for each institution through expert consensus techniques. Once the type and amount of inputs necessary to produce tracer-specific health care services were identified, case-management costs were estimated. Tracer conditions were: hypertension, diabetes, diarrheas, pneumonia, appendicectomy, labor and delivery care, routine ambulatory medical care and vaccines.

Results indicate significant differences with regards to the production of medical services between both sectors and within each one.

The comparative analysis in the cost per case-management for each tracer presents differences that could be explained due to the quantitative and qualitative processes that characterized each institution in the combination of inputs to produce services and for the different costs of the inputs for each of the sectors analyzed, resulting in lower costs in the public sector and higher costs in the private sector, particularly for private health insurance.
