Mathematica Policy Research

This publication finds meaningful variation in disenrollment and churn across Medicaid beneficiary categories. Specifically, beneficiaries with Supplemental Security Income-related eligibility have low rates of disenrollment and high rates of reenrollments. In this research, Mathematica uses data from the Transformed Medicaid Statistical Information System Analytic File to examine rates of disenrollment, churn, and continuous coverage among categories of children and adult Medicaid beneficiaries whose eligibility is related to a disability.

This blog post from Mathematica discusses the importance of partnerships between states and the federal government through highlighting topics covered at NAMD's 2022 conference. Sessions touched on innovations developed as part of recently approved 1115 demonstrations in Arizona, Massachusetts, Oregon, and Arkansas which focused on the ways states are providing whole-person care by addressing the health-related social needs of members. The post also explores Mathematica's work with CMS and states to build stronger measurement and evaluation infrastructure for a broad range of demonstrations, including those addressing substance use disorder, mental illness, and health-related social needs.

People with disabilities are especially vulnerable to the impacts of disasters. To help policymakers understand the need to include people with disabilities in emergency disaster plans, Mathematica researchers created interactive disability natural disaster maps that show how many people with disabilities are living in areas at higher risk of natural disasters.

This Mathematica article summarizes some of their key findings from a recent study utilizing NCI-AD data. The study contributes important information to the field of managed care long-term services and supports (MLTSS) and quality outcomes. One finding shares “MLTSS enrollees rated their experience of care and quality of life more favorably than fee-for-service beneficiaries.”

Mathematica’s Center for Studying Disability Policy recently created interactive state disability maps that reveal important patterns in state- and county-level prevalence of disability among working-age adults as well as how that prevalence compares with Social Security Disability Insurance and Supplemental Security Income participation rates. This information can help policymakers and program managers identify areas with the highest needs or potential benefit discrepancies.

The purpose of this issue brief is to describe the types of foods that participants consumed as part of congregate and home delivered meals. The brief also examines differences between participants and nonparticipants in foods consumed over 24 hours

This brief is based on surveys of local service providers and participants at congregate meal sites. The brief examines whether the effect of congregate meal participation on socialization outcomes differs for participants who attend meal sites that offer social activities and those who attend meal sites that do not offer these activities.

This report assesses the effectiveness of the Title III-C Nutrition Services Program (NSP) under the Older Americans Act. It describes the health and health care utilization of congregate meal and home-delivered meal participants. The report also examines overall wellness measured using longer-term outcomes related to health and avoidance of institutionalization.

This report is one of three reports released around the same time from Mathematica Policy Research focusing on how transition services are being used for youth with disabilities. This report examines states' experiences with a new mandate requiring them to provide pre-employment transition services available to all students with disabilities.

This report is one of three reports released around the same time from Mathematica Policy Research focusing on how transition services are being used for youth with disabilities.
