Abstract
Background— Hypertension control and antiplatelet or oral anticoagulant drugs are the basis for secondary prevention of cerebrovascular events. Family physicians (FPs) are usually involved in both aspects of prevention, but no research has been carried out in Italy to evaluate the behavior of FPs in this field of prevention. Methods— Data concerning 318 Italian FPs and 465 061 patients were extracted from the Health Search Database. Patients with coded diagnoses of stroke and transient ischemic attack (TIA) were selected. Demographic records and information regarding presence of concurrent disease and medical records were also obtained. Logistic regression analyses were carried out to assess whether conditions exist that make appropriate control of blood pressure (BP) and prescription of antiplatelet or anticoagulant drugs more likely. Results— We selected 2555 patients with diagnosis of stroke and 2755 with TIA. Among all of the subjects, 32.6% had no BP recorded. Among the remaining subjects, 58.7% reported uncontrolled BP. Isolated systolic hypertension has been shown in 68.8% of patients with uncontrolled BP. Antiplatelet and anticoagulant drugs were prescribed in 72% of these cases. Factors that made the prescription significantly more unlikely were diagnosis of TIA (odds ratio [OR], 0.47; 95% confidence interval [CI], 0.41 to 0.54), total invalidity (OR, 0.66; 95% CI 0.56 to 0.78), and time from event of 5 years or more (OR, 0.81; 95% CI, 0.70 to 0.94). Conclusions— Italian FPs could improve secondary prevention of cerebrovascular accidents. The primary target of intervention should be the control of systolic BP, and the group of patients with unacceptably high BP should be given priority. All of these patients should have been prescribed antiplatelet drugs or anticoagulant agents, except in cases of extremely short life expectancy or substantial contraindications.
