Abstract

OBJECTIVES: To determine the extent to which relying on only one source of data leads to incomplete assessment of pneumococcal polysaccharide vaccine (PPV) or mammography. DESIGN: Cross-sectional survey. SETTING: An urban Midwestern academic medical center in 1998/99. PARTICIPANTS: Medicare beneficiaries aged 65 and older with at least one health encounter. MEASUREMENTS: Completion of PPV and mammography was assessed using local and Medicare records. The study compared sources of records and assessed association between services and demographics and comorbidity. RESULTS: Adding Medicare data to local data increased the computed 1-year PPV from 8.8% (264/3,002) to 15.0% and increased the 1998/99 mammography rate from 40% (343/847) to 67%. Local data sources missed 40% of PPV and 39% of mammography; Centers for Medicare and Medicaid Services sources missed 50% of PPV and 2% of mammography. The vaccinated were younger than the nonvaccinated (74 vs 76, P<.001). African Americans and those with more comorbidity were less likely to receive PPV over 8 years. Of 555 patients with a Medicare record of mammography, whites and those without Medicaid were significantly less likely to have a local record of mammography (P<.001). CONCLUSION: Neither administrative nor local clinical records provide a complete or accurate assessment of these quality indicators. Accurate assessment of quality indicators requires pooling data from multiple sources across a broad region.
