RESUMO
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.

BACKGROUND: Enhanced primary care models have diffused slowly and shown uneven results. Because their structural features are costly and challenging for small practices to implement, they offer modest rewards for improved performance, and improvement takes time. OBJECTIVE: To test whether a patient-centered medical home (PCMH) model that significantly rewarded cost savings and accommodated small primary care practices was associated with lower spending, fewer hospital admissions, and fewer emergency room visits. DESIGN: We compared medical care expenditures and utilization among adults who participated in the PCMH program to adults who did not participate. We computed difference-in-difference estimates using two-part multivariate generalized linear models for expenditures and negative binomial models for utilization. Control variables included patient demographics, county, chronic condition indicators, and illness severity. PARTICIPANTS: A total of 1,433,297 adults aged 18-64 years, residing in Maryland, Virginia, and the District of Columbia, and insured by CareFirst for at least 3 consecutive months between 2010 and 2013. INTERVENTION: CareFirst implemented enhanced fee-for-service payments to the practices, offered a large retrospective bonus if annual cost and quality targets were exceeded, and provided information and care coordination support. MEASURES: Outcomes were quarterly claims expenditures per member for all covered services, inpatient care, emergency care, and prescription drugs, and quarterly inpatient admissions and emergency room visits. RESULTS: By the third intervention year, annual adjusted total claims payments were $109 per participating member (95 % CI: -$192, -$27), or 2.8 % lower than before the program and compared to those who did not participate. Forty-two percent of the overall decline in spending was explained by lower inpatient care, emergency care, and prescription drug spending. Much of the reduction in inpatient and emergency spending was explained by lower utilization of services. CONCLUSIONS: A PCMH model that does not require practices to make infrastructure investments and that rewards cost savings can reduce spending and utilization.
