AbstractHealth policy makers are struggling to manage health care and spending. To identify strategies for improving health quality and reducing health spending, policy makers need to first understand health risks and outcomes. Despite lacking some desirable clinical detail, existing health care databases, such as national health surveys and claims and enrollment data for insured populations, are often rich in information relating patient characteristics to heath risks and outcomes. They typically encompass more inclusive populations than can feasibly be achieved with new data collection and are valuable resources for informing health policy. This dissertation illustrates how the Medicare Current Beneficiary Survey (MCBS) and MassHealth data can be used to develop models that provide useful estimates of risks and health quality measures. It provides insights into: 1) the benefits of a proxy for the Framingham cardiovascular disease (CVD) risk score, that relies only on variables available in the MCBS, to target health interventions to policy-relevant subgroups, such as elderly Medicare beneficiaries, based on their risk of developing CVD, 2) the importance of setting appropriate risk-adjusted quality of care standards for accountable care organizations (ACOs) based on the characteristics of their enrolled members, and 3) the outsized effect of high- frequency hospital users on re-admission measures and possibly other quality measures. This work develops tools that can be used to identify and support care of vulnerable patients to both improve their health outcomes and reduce spending – an important step on the road to health equity.

A Public Health Framework for the State Mental Health Authority: A Call for Action by Massachusetts Consumers and Family MembersDelman, Jonathan (2006-01-01)During the Spring of 2006, Consumer Quality Initiatives (CQI) conducted 20 focus groups across the state, 12 with adults with mental illness, 3 with parents of youth with serious emotional disorder, 2 with youth with SED, 1 with family members of adult consumers, and 2 with youth in transition. Supported by a contract with Massachusetts Department of Mental Health (DMH), the goal was to assist DMH in framing the criteria for its upcoming reprocurement. Our findings reveal a frustration with an approach to health care delivery that focuses primarily on the provision of psychiatric care (egs, medication, therapy, hospitalization). We reviewed the focus group reports to identify the most significant themes, which clustered within eight broad categories.
Policy Brief: Addressing Social Determinants of Health through Community Health Workers: A Call to ActionLondon, Katharine; Damio, Grace; Ferrazo, Meredith; Perez-Escamalla, Rafael; Wiggins, Noelle (2018-01-30)This technical report was compiled by the Hispanic Health Council in partnership with Southwestern AHEC and a panel of Community Health Worker Policy Research Experts which included our Katharine London from the Center for Health Law and Economics. The report offers a number of policy recommendations for community health workers for communities that might benefit from community-based services. The report offers recommendations on; payment of community health workers; community health worker caseloads; community health worker recruitment; community health worker training; reflective and trauma-informed mentoring and supportive supervision of community health workers; integration of community health workers into care teams; documenting the effect of community heal worker services on social determination of health. The Hispanic Health Council believes a service design that effectively supports community health workers would incorporate the seven areas of policy recommendation included in this report.
Making the Case for Sustainable Funding for Community Health Worker Services: Talking to Payers and ProvidersLondon, Katharine (2018-01-27)In this presentation, Katharine London of the Center for Health Law and Economics makes her case for offering sustainable funding for community health worker services. Research has shown community health workers can have a distinct impact on health systems, helping them improve population health and contain costs, while also promoting health equity and community engagement. This presentation was designed to assist CHWs and other advocates in engaging with policymakers and payers to support CHW sustainability and develop a financial plan for their CHW work. It was presented as part of a CHW Sustainability event held at the Families USA’s annual conference, Health Action 2018: Staying Strong for America’s Families, in Washington, DC.
