When a Usual Source of Care and Usual Provider Matter: Adult Prevention and Screening Services

Abstract
OBJECTIVE To examine whether the usual source of preventive care, (having a usual place for care only or the combination of a usual place and provider compared with no usual source of preventive care) is associated with adults receiving recommended screening and prevention services. DESIGN Using cross-sectional survey data for 24,138 adults (ages 18–64) from the 1999 National Health Interview Survey (NHIS), we estimated adjusted odds ratios using separate logistic regression models for receipt of five preventive services: influenza vaccine, Pap smear, mammogram, clinical breast exam, and prostate specific antigen. RESULTS Having both a usual place and a usual provider was consistently associated with increased odds for receiving preventive care/screening services compared to having a place only or neither. Adults ages 50–64 with a usual place/provider had 2.8 times greater odds of receiving a past year flu shot compared with those who had neither. Men ages 50–64 with a usual place/provider had nearly 10 times higher odds of receiving a PSA test compared with men who had neither. Having a usual place/provider compared with having neither was associated with 3.9 times higher odds of clinical breast exam among women ages 20–64, 4.1 times higher odds of Pap testing among women ages 21–64, and 4.8 times higher odds of mammogram among women ages 40–64. CONCLUSIONS Having both a usual place and usual provider is a key variable in determining whether adults receive recommended screening and prevention services and should be considered a fundamental component of any medical home model for adults.
