Notes: Numbers in the table are percentage values for practice characteristics and mean percentage values for patient characteristics. The sample includes all practices with at least one valid ABCS outcome measure during the study period (n = 1278 for EvidenceNOW practices; n = 613 for DARTNet practices). Practice location is based on the rural-urban commuting areas using 2010 Census data. Numbers for insurance status and race/ethnicity are average percentage values. They do not sum to 100 percent because practices were not required to report estimates that did so. Dual eligible insurance status includes patients receiving both Medicaid and Medicare. Demonstration programs include State Innovation Models Initiative, Comprehensive Primary Care Initiative, Transforming Clinical Practice Initiative–Support and Alignment Network, Community Health Worker training program, Blue Cross/Blue Shield patient-centered medical home program, Association of State and Territorial Health Officials’ Million Hearts State Learning Collaborative, Million Hearts: Cardiovascular Disease Risk Reduction Model, and any other program identified by the practice. HMO: Health Management Organization; FQHC: Federally Qualified Health Center; EHR: electronic health records; MUA: Meaningful Use. Sources: EvidenceNOW practice survey; DARTNet practice data.
