OBJECTIVE: to evaluate the cost of the treatment of the diabetic patients in our means from the perspective of the NHS and the percentage of patients treated in monotherapy and the used combinations more. METHODS: The total of patients including in the program of diabetes in our means was of 207. 120 clinical histories by means of simple sampling studied random coming from which they went to consultation between the 1 of November of 2004 and the 31 of October of the 2005. The costs of the medical consultations and infirmary were obtained from the Sanitary District of Axarquía (Málaga Est), the cost of the used medication of the nomenclátor of the Andalusian Heatlh Service (SAS). RESULTS. 67% of the patients showed a good control of the HbA1c (according to criteria of ADA, 2006) with average numbers of 6.08% (IC95%: 5.95-6.21). The average total cost by patient was of 534 euros/y (34% by the prescription). The cost by patient according to the degree of control of the DM was: 433€ for good control (HbA1c <6%), 496 € for a normal control (6%7%) and 685€ for bad control (HbA1c>7%). These differences were significant (p=0.032). CONCLUSIONS: The percentage of control of the diabetics in our means is than acceptable more. Differences between gender in the degree of control and use of resources exist, although they were not significant statistically. The diabetics badly controlled cause a greater use of sanitary resources in primary care. Most of the diabetics in our means is controlled with monotherapy. It would be necessary to improve the sociosanitary attention of these patients and to include the cardiovascular risk like one more a measurement of control and effectiveness.
