Despite their value, comprehensive diabetes care and screening for common cancers remain underutilized. We examined the association between participation in a patient-centered medical home (PCMH) program with strong financial incentives and receipt of preventive care in the first 5 years after program launch. Using multivariate regression analysis, we compared outcomes for adults under the care of participating primary care providers (PCPs) with adults under the care of nonparticipating PCPs. Outcomes were breast, cervical and colorectal cancer screenings, and elements of diabetes care. The analytic sample included 818,623 adults living in Maryland, Virginia, or the District of Columbia, and enrolled with CareFirst for at least 1 year during 2010–2015. By Year 5, enrollees in the intervention group were 7.9 (95% confidence interval [CI]: 2.8–13.0), 6.1 (95% CI: 1.4–10.7), 3.1 (95% CI: 2.1–4.0), and 7.6 (95% CI: 7.0–8.2) percentage points more likely to undergo HbA1c tests, nephropathy examinations, breast, and cervical cancer screenings, respectively. We found no significant change in the propensity to receive colorectal cancer screening or an eye examination. Our study shows that a PCMH program with strong financial incentives can raise the provision of preventive care but could require additional adjustment.
