Continuity of care is much valued by patients and doctors. It is seen as a core feature of the discipline in general practice, although there is little supporting evidence that it leads to improvement in the care given during the management of patients with chronic disorders. This study shows that increased continuity is not associated with improved clinical care in the secondary prevention of coronary heart disease. The study also shows that it is possible to maintain high continuity for a chronic condition in a group practice with flexible working arrangements. This has implications for recruitment of future general practitioners.
