[Supply of essential drugs in units specialized in the treatment of chronic diseases in Mexico in 2012]. / Abasto y surtimiento de medicamentos en unidades especializadas en la atención de enfermedades crónicas en México en 2012.

OBJECTIVE: To quantify the supply of essential drugs and the fully filled-in prescription level in the Units Specialized in the Treatment of Chronic Diseases (UNEMES-EC) in Mexico. MATERIALS AND METHODS: The supply and prescription indicators were measured in 30 of the 86 existing UNEMES-EC. The supply of drugs was recorded using a list of 17 essential drugs related to the treatment of diabetes, hypertension, overweight and obesity. The information on fully filled-in prescriptions was obtained through a questionnaire applied to 1 200 health care users. RESULTS: Only 13.3% of these units showed a complete supply of the 17 essential drugs: Supply levels were higher in units with external drugstore service. 35% of the interviewed patients reported out-of-pocket expenditures in medicines. CONCLUSION: UNEMES-EC should improve their levels of drug supply and fully filled-in prescriptions to reduce out-of-pocket expenditures.
