Organizational factors influence the quality of preventive care. Combining facility-level data from a national organizational survey and centrally available, externally abstracted chart review data on prevention performance, we assessed the relationship between structural features of primary care departments and the quality of preventive care delivered. Primary care practice resources were significantly and positively associated with the delivery of 6 of 9 preventive services. Adjusting for facility size and academic affiliation, these resource arrangements accounted for substantial variation in 8 of 9 services. Assuring high-quality prevention performance requires ongoing investment in primary care–based infrastructure.
