Comparative Effectiveness Research


Project Name Evaluation of Aetna's Care Coordination Program
Client Aetna
Description This was a retrospective study of the effects of Aetna’s Medicare managed care (Medicare Advantage) program on enrollees in the northeastern United States (New York, New Jersey, Pennsylvania, and Maryland). Aetna’s nurses provided a case management intervention to approximately 18 percent of its enrolled population, and other, less intense interventions to additional members. The study compared all plan enrollees to a non-experimentally matched comparison group in fee-for-service Medicare in the same market areas. Outcomes of interest included hospital admissions and days, emergency room admissions, skilled nursing facility admissions and days, and mortality.
   
Project Name Establishing Federal Resources to Support the Patient-Centered Medical Home Concept

Project Name Evaluation of the Medicaid Value Program (MVP): Health Supports for Consumers with Chronic Conditions
Client Center for Health Care Strategies, Inc.
Description The Medicaid Value Program sought to test interventions seeking to improve care for adult Medicaid beneficiaries with multiple chronic conditions. The program was funded by a grant from Kaiser Permanente, with additional funding from the Robert Wood Johnson Foundation. Ten teams all sought to improve care for Medicaid beneficiaries, but they did so in a variety of ways and focused on different populations. Seven targeted their interventions to patients, all but one of them using a case management and coordination model to improve care. The exception augmented a pre-existing disease management program with in-person patient education. Others targeted providers to improve the quality of patient care. Mathematica’s evaluation identified factors that contributed to successful implementation of grantee interventions and lessons learned that would contribute to replicability and sustainability of their programs.
   
Project Name Community-Based Care Transitions Program (CCTP) Implementation and Monitoring
Client Centers for Medicare & Medicaid Services (CMS)
Description The Community-Based Care Transitions Program, a major component of the Partnership for Patients Pledge created by the Affordable Care Act, will provide $500 million in funding over the next five years to test models for improving care transitions from the hospital to the community for Medicare beneficiaries at high risk of readmission. As the implementation and monitoring contractor, we are (1) developing and implementing an electronic system for collecting, validating, and paying invoices from community-based organizations (CBOs), and (2) monitoring CBOs' progress toward meeting their performance targets, as well as the program's impact on federal expenditures. Specifically, we are using Medicare claims and information collected through a participant experience survey to calculate 30-day hospital readmission rates, primary care provider follow-up visit rates, patient activation scores, and adverse event measures, such as 30-day emergency department visit, observation stay, and mortality rates. CMS will use the results to provide real-time performance feedback to CBOs and their hospital partners and to determine whether CBO contracts will be renewed after an initial two-year performance period.
