The patient-centered medical home has become a prominent model for reforming the way health care is delivered to patients. The model offers a robust system of primary care combined with practice innovations and new payment methods. But scant information exists about the extent to which typical US physician practices have implemented this model and its processes of care, or about the factors associated with implementation. In this article we provide the first national data on the use of medical home processes such as chronic disease registries, nurse care managers, and systems to incorporate patient feedback, among 1,325 small and medium-size physician practices. We found that on average, practices used just one-fifth of the patientcentered medical home processes measured as part of this study. We also identify internal capabilities and external incentives associated with the greater use of medical home processes.T he patient-centered medical home model of health care delivery system reform was featured prominently in the Affordable Care Act of 2010. The model was developed by the primary care specialty societies in 2007. It has been endorsed by a broad coalition of purchasers, payers, providers, consumers, and other health care stakeholders. It emphasizes a robust system of primary care combined with practice innovations and new payment models.

Physician practices that are currently participating in ACOs appear to be relatively large, or to be members of an IPA or PHO, are less likely to be hospital-owned and are more likely to use more care management processes than nonparticipating practices.

BACKGROUND Routinely recommended screening for breast, cervical, and colorectal cancers can significantly reduce mortality from these types of cancer, yet screening is underutilized among Asians. Surveys rely on self-report and often are underpowered for analysis by Asian ethnicities. Electronic health records include validated (as opposed to recall-based) rates of cancer screening. In this paper we seek to better understand cancer screening patterns in a population of insured Asian Americans. METHODS We calculated rates of compliance with cervical, breast, and colorectal cancer screening among Asians from an EHR population, and compared them to non-Hispanic whites. We performed multivariable modeling to evaluate potential predictors (at the provider- and patient- level) of screening completion among Asian patients. RESULTS Aggregation of Asian subgroups masked heterogeneity in screening rates. Asian Indians and Native Hawaiians and Pacific Islanders had the lowest rates of screening in our sample, well below that of non-Hispanic whites. In multivariable analyses, screening completion was negatively associated with patient-physician language discordance for mammography (OR:0.81 95% CI:0.71–0.92) and colorectal cancer screening (OR:0.79 CI:0.72–0.87) and positively associated with patient-provider gender concordance for mammography (OR:1.16 CI:1.00–1.34) and cervical cancer screening (OR:1.66 CI:1.51–1.82). Additionally, patient enrollment in online health services increased mammography (OR:1.32 CI:1.20–1.46) and cervical cancer screening (OR:1.31 CI:1.24–1.37). CONCLUSIONS Language- and gender- concordant primary care providers, and culturally tailored online health resources may help improve preventive cancer screening in Asian patient populations. IMPACT This study demonstrates how use of EHR data can inform investigations of primary prevention practices within the healthcare delivery setting.

Key PointsQuestionWas the Centers for Medicare & Medicaid Services Oncology Care Model (OCM), an alternative payment model for cancer patients undergoing chemotherapy, associated with differences in Medicare spending, utilization, quality, and patient experience over the model’s first 3 years?FindingsIn this exploratory difference-in-differences study of Medicare fee-for-service beneficiaries with cancer undergoing chemotherapy (483 310 beneficiaries with 987 332 episodes treated at 201 OCM participating practices and 557 354 beneficiaries with 1 122 597 episodes treated at 534 comparison practices), OCM was associated with a statistically significant relative decrease in total episode payments of $297 that was not sufficient to cover the costs of care coordination or performance-based payments. There were no statistically significant differences in most measures of utilization, quality, or patient experiences.MeaningIn its first 3 years, the OCM was significantly associated with modestly lower Medicare episode payments that did not offset model payments to participating practices, and there were no significant differences in most utilization, quality, or patient experience outcomes.

Practice ownership and Medicaid revenue may affect the use of care management processes (CMPs) for chronic conditions and expansion of health information technology (HIT). Using a national cohort of medical practices, we compared the use of CMPs and HIT from 2006/2008 to 2013 by practice ownership and level of Medicaid revenue. Poisson regression models estimated changes in CMP use, and linear regression estimated changes in HIT, by practice ownership and Medicaid patient revenue, controlling for other practice characteristics. Compared with physician-owned practices, system-owned practices adopted a greater number of CMPs and HIT functions over time (p < .001). High Medicaid revenue (≥30.0%) was associated with less adoption of CMPs (p < .001) and HIT (p < .01). System-owned practices (p < .001) and community health centers (p < .001) with high Medicaid revenue were more likely than physician-owned practices with high Medicaid revenue to adopt CMPs over time. System and community health center ownership appear to help high Medicaid practices overcome CMP adoption constraints.
