[Management of arterial hypertension: results of a Tunisian general practitioner survey].

The control of arterial hypertension (HT) is an endlessly hoped objective but usually not reached. Several factors are determinants. The physician role is crucial in the HT prevention. In order to evaluate knowledge, attitudes and behaviours of Tunisian physicians in HT management, we conducted a cross sectional study in 2002 using a self administered questionnaire addressed to physicians working in private and public sectors. 380 generalists participated to this study. 95.5% of them confirmed that HT constitutes a public health problem. 81.1% saw at least 4 patients with HT a week. 95% insisted on the importance of the primary prevention. 90% took care themselves patients. 71.5% confirmed the importance of a training and an entrainement for the measure of the blood pressure (BP). 3.7% made diagnosis after a single visit and 10.9% confirmed it only from described symptoms. 20.4% of the generalists chose the old classification as objective level of BP. Thiazidic Diuretics and beta blockers were most prescribed medicines in first intention. 9.4% stopped the treatment after stabilization of blood pressure. 60% of generalists had inadequate behaviour facing a not stabilized BP. Non observance of treatment by patients was indicated by 31% of the generalists, cost and break of the medicines' stock and disappearance of symptoms were the main causes advanced by the generalists. This study shows the existence of gaps in generalists' practical behaviour treating this disease. Measures aiming the medical practice improvement turn out necessary in particular the sensitization of the generalists by an adequate university training and a continuous medical training, and a regular evaluation of the national program of hypertension prevention and management.
