Purpose: Although having a continuous relationship with a physician is a defining feature of primary care, few studies have evaluated the effect of this on chronic disease management. This aim of this study was to examine whether having a regular physician is associated with improvements in reaching treatment goals for patients with diabetes.Methods: Through the use of a diabetes registry, patients diagnosed with diabetes mellitus for a minimum of 6 months cared for in a large, single academic family medicine practice were compared based on whether they had a regular physician or not. The 2 groups were compared in the frequency in which they achieved goals for management of glycated hemoglobin, blood pressure, low-density lipoprotein cholesterol, and other aspects of diabetes care.Results: Patients with a regular provider were slightly older than those without a provider (57.5 years vs. 50.9 years; P ؍ .002), but the gender distribution and percent who were smokers was the same. In assessing diabetes quality measures, patients with a regular provider had lower average levels of glycated hemoglobin (7.70 vs 8.53; P ؍ .01), but no difference was noted in the percentage achieving a goal of <7.0. No differences were noted between the groups in either the average systolic or diastolic blood pressures or low-density lipoprotein cholesterol or in the percentages of patients achieving recognized goals for these measures. When examining other preventive services, patients with a regular provider were more likely to receive an influenza immunization within the last year (51.8% vs 35.6%; P ؍ .02) but no more likely to receive a pneumococcal vaccine or take an aspirin each day.
Conclusion: This study suggests that there are few benefits for patients with diabetes in having an established regular provider over having a regular place of service. (J Am Board Fam Med 2010;23: 82-87.)Along with first contact, comprehensiveness, and coordination of care, continuity is considered one of the 4 cornerstones of primary care. 1 The belief in the value of patient continuity with a regular provider who can develop intimate knowledge of the patient's clinical condition and establish a trusting, healing relationship with the patient is widely accepted among primary care providers and health policy experts. Having a regular physician has been shown to have a beneficial effect on a large range of health care services, including preventive services in children 2,3 and reductions in hospital and emergency department use among patients with chronic health problems.
4,5The effects of having a regular physician would seem to have the greatest benefit for patients who have complex chronic diseases for which the frequency of care and the necessity of multiple therapeutic interventions would be enhanced by an ongoing relationship with a single physician. However, there is conflicting evidence that having a regular physician makes a difference in the management of diabetes, a highly complex chronic medical illness. In an analysis of diabetes i...
