OBJECTIVES:: Adherence of patients is strongly associated with clinical outcomes. The aim of this study is to compare the compliance of clinical providers to the milestones of local clinical guidelines, with the estimated differences in metabolic results that are associated with the attendance at the health-care multidisciplinary services. METHODS:: It is a Cross-sectional study, including information on 7908 patients in 2015. It uses day-to-day clinical records and administrative data from the registries available for the Fondo Colombiano de Enfermedades de Alto Costo –Cuenta de Alto Costo in collaboration with the Health Economics & Outcomes Research Team – HEORT. Adherence to Colombian Diabetic Guideline was measured by ratios of compliance. Assistance to medical services and clinical outcomes was transformed to categorically variables, Fisher’s Exact test was used to determine the difference between groups. STATA V13.0 software was used to analyze data. RESULTS:: Observed clinical adherence of health care providers to the local clinical guidelines showed a global ratio of 43%. There were statistically significant differences between HbA1c, Total Cholesterol, HDL, LDL, and Clinical follow-up associated with patient’s attendance to follow-ups with the Nutritionist, the Physician, the Internist, and the Ophthalmologist, in most of the cases. CONCLUSIONS:: There is an important association between metabolic control and attendance to clinical services, which aid to conclude about its increased importance. However, the observed 43% of adherence to the Colombian Diabetes Guidelines, must be regarded with the utmost care for the very particular structure of the Colombian health insurance system. Specifically, such percentage can be affected by external processes experienced by the patient or simply due to the physicians’ praxis. Hence, the upturn in the attendance frequency to specialists may cause an improvement in metabolic results, in consequence, lowering the hospitalization rates.
