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.KEY WORDS: source of care; medical home; usual provider; preventive care; health insurance.

Why do People Avoid Medical Care? A Qualitative Study Using National Data

“…7,21,22,[42][43][44] With the advent of the Affordable Care Act (ACA), lack of health insurance may become less of a barrier, but our results indicate that inadequate health insurance and high co-pays are also reasons for avoiding medical care, as well as numerous other reasons that may not be abated by the ACA. Interventions targeting these barriers are an important area for continued research.…”

Characteristics of Community Mental Health Clinics Associated With Treatment Engagement

“…We ran a total of five models, one for each clinic characteristic. In order to examine whether clinic characteristics were associated with engagement, a "predictive margins" method (12), also known as the "recycled predictions" method (13)(14)(15), was used. In this method, model parameters from the original population were used to predict engagement for each clinic characteristic, with adjustment for all other observed individual-level characteristics (age, gender, diagnosis, insurance status, disability days, interview language, and intervention status).…”

Principles of the Patient-Centered Medical Home and Preventive Services Delivery

“…[10][11][12][13][14][15][16]25 Having a greater number of visits and a well-visit in the past 5 years had the greatest effect on preventive services delivery rates. This fi nding suggests that having more contacts with the primary care practice and having a visit dedicated to preventive care are important strategies to increase preventive services.…”
