Sub-optimal drug treatment of diabetes and cardiovascular risk in diabetic patients in Turkey. A countrywide survey.

OBJECTIVES

The present study is a snapshot of how diabetic patients are treated for diabetes and coexisting cardiovascular risk factors in Turkey. We also addressed the question of what percentage of these patients are treated appropriately according to the current guidelines. Next step will be to determine which pharmacological treatment strategies affect mortality and morbidity in these patients and whether there are regional differences in these outcomes.

METHODS

To get a representative picture, Turkey was splitted into four parts with different ethnic and socioeconomic features then centers were randomized within each of these parts. Number of the centers in a region were calculated according to the population of that region. 305 physicians in 11 cities participated in data collection during a period of 3 months. Consecutive 2226 diabetic patients patients who were above 55 years of age were included. Detailed information was obtained about the demographic features and the cardiovascular risk factor and diabetes status of the patients together with relevant drug treatment. Laboratory analyses were done locally and recorded if performed during the last 3 months.

RESULTS

Most patients were treated with oral antidiabetic monotherapy regardless of diabetes duration, metabolic control and complication and cardiovascular risk factor status. There was a trend among physicians except for endocrinologists to underprescribe insulin. Monotherapy also was the main mode of treatment for hypertension. Angiotensin converting enzyme inhibitors were generally not used as first line treatment contrary to the recommendations and angiotensin converting enzyme inhibitors and angiotensin receptor blockers are not prescribed for renoprotection in microalbuminuric patients. Statins, fibrates, metformin and aspirin were largely underused.

CONCLUSION

The present study indicates that diabetic patients are undertreated in Turkey. Therefore every effort should be spent to implement current guidelines in diabetic patients in order to prevent macro and microvascular complications of diabetes.
