Abstract

Context Rates of preventive services remain below national goals. Objective To identify characteristics of physicians and their practices that are associated with the quality of preventive care their patients receive. Design Cross-sectional analysis of data on US physician respondents to the 20002001 Community Tracking Study Physician Survey linked to claims data on Medicare beneficiaries they treated in 2001. Physician variables included training and qualifications and sex. Practice setting variables included practice type, size, sources of revenue, and access to information technology. Analyses were adjusted for patient demographics and comorbidity, as well as community characteristics. Setting and Participants Primary care delivered by 3660 physicians providing usual care to 24 581 Medicare beneficiaries aged 65 years and older. Main Outcome Measures Proportion of eligible beneficiaries receiving each of 6 preventive services: diabetic monitoring with hemoglobin A(1c) measurement or eye examinations, screening for colon or breast cancer, and vaccination for influenza or pneumococcus in 2001. Results Overall, the proportion of beneficiaries receiving services was below national goals. Physician and, more consistently, practice-level characteristics were both associated with differences in the delivery of services. The strongest associations were with practice type and the percentage of practice revenue derived from Medicaid. For instance, beneficiaries receiving usual care in practices with less than 6% of revenue from Medicaid were more likely than those with more than 15% of revenue derived from Medicaid to receive diabetic eye examinations (48.9% vs43%; P=.02), hemoglobin A(1c) monitoring (61.2% vs 48.4%; P
