How do general practitioners manage patients at risk from stroke?

This study assessed by means of a postal questionnaire how general practitioners (GPs) manage patients at risk from stroke. Of the 640 GPs sent a questionnaire, 294 (46%) replied. In patients with a recent transient ischaemic attack or minor ischaemic stroke, 24% of responding GPs would not arrange any investigations. Sixty-one per cent refer under half of their patients for further investigation, although 99% of GPs would commence aspirin. Seventy-seven per cent of GPs were aware of the benefits of carotid surgery. For patients in atrial fibrillation, most GPs (77%) thought that warfarin reduced stroke rates, but only 20% would consider commencing warfarin, although 26% would commence aspirin. In hypertensive patients, the GPs' threshold for treatment ranged from 135 to 200mmHg systolic (median 160mmHg), and from 90 to 110mmHg diastolic (median 100mmHg). Most GPs (84%) would treat isolated systolic hypertension with a median threshold of 180mmHg (range 140-240mmHg). The results of this study suggest that some patients at risk from stroke may not receive optimal investigation and treatment in the community.
