[Cost-effectiveness of treatment of type 2 diabetes mellitus in México].

BACKGROUND: Type 2 Diabetes Mellitus (DM2) is a public health and socioeconomic problem, generating direct medical costs for its treatment.

OBJECTIVE: To analyze the cost-effectiveness of monotherapy and bitherapy treatments in patients with DM2.

METHODS: Cost-effectiveness, observational, ambispective, cross-sectional and analytical analysis of files in a first level medical unit. The data in the cost matrix was executed with the Office Excel 2010 program; the most prescribed drug was identified and compared with monotherapy and bitherapy.

RESULTS: The annual direct medical costs of the total population were drug cost $118,561.70MN, hospitalization cost $243,756.00MN, consultation cost $327,414.00MN and clinical trial cost $2416.79MN, obtaining an annual total of $692,148.58MN. metformin was the most indicated in monotherapy (88.4%) and as standard therapy it has higher cost-effectiveness compared to glibenclamide. In bitherapy it was metformin/glibenclamide (35.7%) versus the therapeutics of metformin/NPH insulin, metformin/insulin glargine and metformin/dapagliflozin, which had a better cost-effective result, with an incremental cost effectiveness of -$1,128,428.50MN, -$34,365.00 MN, -$119,848.97MN respectively.

CONCLUSIONS: Metformin presented a better cost-effectiveness ratio in monotherapy, while in bitherapy it was the metformin/NPH insulin association.
