Abstract Rationale, aims and objectives To compare the pharmacotherapeutic approaches to diabetic hypertension of family physicians (FPs) and general practitioners (GPs). Methods A retrospective prescription‐based study was conducted in 15 out of a total of 20 health centres, involving 115 primary care physicians – 77 FPs and 38 GPs, representing 74% of the primary care physicians of Bahrain. Prescriptions were collected during May and June 2000 to comprise a study population of 1266 diabetic‐hypertensive patients. Results As monotherapy, angiotensin‐converting enzyme (ACE) inhibitors (37.9%) and β‐blockers (38.3%) were the most commonly prescribed classes of antihypertensives by FPs and GPs, respectively. Calcium channel blockers (CCBs) were ranked third by both categories of physicians. For two‐drug combinations, a β‐blocker and an ACE inhibitor was the combination of choice for both physician categories. Patients managed by the FPs were more likely to receive a β‐blocker–CCB combination (17.4 vs. 14.9%) or a diuretic–ACE inhibitor combination (16.7 vs. 11.4%) and less likely to receive a β‐blocker–diuretic combination (11.8 vs. 16.7%) than those managed by the GPs. The proportion of patients receiving antihypertensive combinations was 40.6 and 38.5% for FPs and GPs, respectively. While the GPs prescribed CCB as a monotherapy to the elderly most often, the FPs choice was a β‐blocker. Diuretics were less preferred by both FPs and GPs. β‐Blocker–ACE inhibitor was again the most preferred combination of both FPs and GPs. FPs prescribed CCB–β‐blocker combinations more often than GPs ( P = 0.01), whereas CCB–ACE inhibitor combinations were less preferred ( P = 0.09). A trend towards excessive use of short‐acting nifedipine as monotherapy for elderly patients, both by FPs and by GPs, was noticed. Glibenclamide, alone or in combination with metformin, was the foremost antidiabetic drug prescribed by FPs and GPs. Middle‐aged (45–64 years) patients seen by GPs were more likely to receive glibenclamide than those treated by FPs ( P = 0.001) and less likely to receive gliclazide ( P = 0.01). Combinations of a β‐blocker with either glibenclamide or insulin were prescribed considerably more often by GPs. Conclusions Within the same practice setting, a substantial difference was observed between FPs and GPs in terms of preference for different classes of drugs in the management of diabetic hypertension. The compliance of both FPs and GPs was suboptimal; overall, the compliance of the FPs was closer to the recommended guidelines, however. Educational programmes should specifically address these inadequacies in order to improve the quality of health care.
