Primary care practice coordination versus physician continuity.

BACKGROUND AND OBJECTIVES: This study assesses the influence of primary care continuity--both clinician and system--on patient outcomes. We consider the presumed benefits of physician continuity and practice coordination within a multi-specialty group. METHODS: The practices of 194 family physicians and general internists caring for 320000 adult members of a health maintenance organization were evaluated using four aggregate measures of outcomes--cancer screening in women, diabetic management examinations, patient satisfaction ratings, and ambulatory costs. Physician continuity and practice coordination were assessed using sequential sets of multiple regression models while controlling for patient panel and physician characteristics. RESULTS: Physician continuity, defined as seeing the same designated physician during 1 year, was not associated with any patient outcome. Practice coordination, measured by shared practice, team tenure, and medical clinic size, was significantly associated with three of the outcomes. Both medical clinic size and shared practice were associated with higher rates of cancer screening and diabetic management examinations. Team tenure exhibited a significant positive association with cancer screening, diabetic management, and patient satisfaction. CONCLUSIONS: While physician continuity was not associated with patient outcomes, primary care practice structure was. Practice coordination should be assessed to identify mechanisms to support improved care.

Effect of part-time practice on patient outcomes.

BACKGROUND: Primary care physicians are spending fewer hours in direct patient care, yet it is not known whether reduced hours are associated with differences in patient outcomes. OBJECTIVE: To determine whether patient outcomes vary with physicians' clinic hours. DESIGN: Cross-sectional retrospective design assessing primary care practices in 1998. SETTING: All 25 outpatient-clinics of a single medical group in western Washington. PARTICIPANTS: One hundred ninety-four family practitioners and general internists, 80% of whom were part-time, who provided ambulatory primary care services to specified HMO patient panels. Physician appointment hours ranged from 10 to 35 per week (30% to 100% of full time). MEASUREMENTS: Twenty-three measures of individual primary care physician performance collected in an administrative database were aggregated into 4 outcome measures: cancer screening, diabetic management, patient satisfaction, and ambulatory costs. Multivariate regression on each of the 4 outcomes controlled for characteristics of physicians (administrative role, gender, seniority) and patient panels (size, case mix, age, gender). MAIN RESULTS: While the effects were small, part-time physicians had significantly higher rates for cancer screening (4% higher, P =.001), diabetic management (3% higher, P =.033), and for patient satisfaction (3% higher, P =.035). After controlling for potential confounders, there was no significant association with patient satisfaction (P =.212) or ambulatory costs (P =.323). CONCLUSIONS: Primary care physicians working fewer clinical hours were associated with higher quality performance than were physicians working longer hours, but with patient satisfaction and ambulatory costs similar to those of physicians working longer hours. The trend toward part-time clinical practice by primary care physicians may occur without harm to patient outcomes.
