    Abstract:
    OBJECTIVE: To evaluate control of blood pressure (BP) and diabetes and the associated risk factors in diabetic hypertensives treated by diabetic clinic primary care physicians. METHODS: A retrospective analysis of the medical records of diabetic hypertensives from six primary care diabetic clinics in Bahrain. RESULTS: The recommended BP target <130/<85 mmHg and of glycosylated haemoglobin (HbA1C) <7% were achieved in 7.5% and 14.5%, respectively. Most of the patients with uncontrolled BP and HbA(1C) were at high cardiovascular risk. More patients were on antihypertensive monotherapy than on combination therapy (60.6% vs. 36.7%; P<0.0001). The recommended two- and three-antihypertensive drug combinations were less often prescribed. In high-risk patients glycaemic control achieved was poor: antidiabetic combination therapy vs. monotherapy did not significantly differ. Inappropriate prescribing practices, such as the use of immediate-release nifedipine monotherapy, use of sulphonylurea instead of metformin in obese patients, and a trend towards prescribing of glyburide rather than a gliclazide in the elderly, were observed. Lipid-lowering (13.5%) and antiplatelet (12.8%) drugs were infrequently prescribed. CONCLUSIONS: Hypertension and diabetes in patients treated at the primary care diabetic clinics were inadequately controlled. In several instances, mono- and combination antihypertensives prescribed were irrational. Lipid-lowering and platelet aggregation inhibition strategies have received little attention. Intensive antihypertensive and antidiabetic complementary combination therapy should be encouraged. Continuous professional education of diabetic clinic physicians and expert-supervised diabetic clinics are desirable.
