Additional Information: CMS contracted L&M Policy Research LLC and its partners—Abt Associates, Avalere Health, Social & Scientific Systems, and Truven Health Analytics—to conduct the claims and CAHPS analyses. SAS EG (version 5.1) was used to create the claims files, and STATA (version 13.0) was used to analyze claims and CAHPS data. CMS provided guidance with performing and interpreting the analyses and designed and wrote the manuscript.
This article is based on the work of the evaluation contractors for the Evaluation of CMMI Accountable Care Organization Initiative performed under Contract HHSM-500-2011-00019i/HHSM-500-T0002 with the Centers for Medicare & Medicaid Services (CMS). CMS provided access to the data to the evaluation contractors to perform analyses under the guidance of Drs Nyweide, Lee, and Cuerdon. In conjunction with the contractors, Drs Nyweide, Lee, and Cuerdon designed the study and helped with interpretation of the data.
