Abstract
The aim of this study was to investigate the diagnostic approach to recently diagnosed hypertensive patients by primary care physicians in Italy and to find out whether general practitioners manage these patients according to 1999 WHO/ISH guideline recommendations. In total, 228 consecutive patients (117 men and 111 women, mean age 51+/-12 years) with recently diagnosed hypertension (<2 years) referred for the first time to six outpatient hypertension centres throughout Italy were included in the study. The primary care physicians' approach was evaluated during the specialist visit by a specific questionnaire containing detailed questions about diagnostic work-up and treatment made at the time of the first diagnosis of hypertension. At the study visit, 71% of the patients were on treatment with antihypertensive drugs and 18.7% of them had blood pressure (BP) values lower than 140/90 mmHg. A complete clinical and laboratory evaluation according to the minimum work-up suggested by the guidelines had been carried out in only 10% of the patients. A full physical examination had been performed in 60% of the patients, electrocardiogram in 54%, serum total cholesterol in 53%, glucose in 49%, creatinine in 49%, urine analysis in 46%, potassium in 42%, and fundus oculi in 19%. Additional investigations such as ambulatory BP monitoring, echocardiogram, carotid ultrasonogram, and microalbuminuria had been carried out in a minority of patients (21, 18, 9, and 3%, respectively). The impact on hypertension guidelines on patients' management in everyday primary care practice appears marginal. Thus, our findings indicate that the majority of general practitioners manage hypertensive patients according to a simple BP-based approach rather than a more integrated approach based on global risk stratification.
