Mathematica's evaluation of Medicaid Section 1115 waiver demonstrations, approximately 40 in number, seeks to assess the implementation and outcomes of four different types of innovations and help CMCS shift toward data-driven decision making for future waiver approvals.
- Evaluation design and methods
- Provider payment reform
- Insurance benefit design
- Program integrity
- Quantitative disability research
- Behavioral economics
- Economic Well Being and Income Support
- Transition to Adulthood
- Medicaid and CHIP
- Human Services
Kara Contreary specializes in quantitative program evaluation design and implementation. Her work spans a variety of topic areas, including increasing access to care for low-income populations, promoting employment of individuals with disabilities, and improving the efficiency of health care purchasing.

In addition, she leads quantitative analyses of the effects of section 1115 Medicaid demonstrations on health care utilization and cost among newly enrolled beneficiaries. She is principal investigator for a Disability Research Consortium project using predictive analytics for early identification of claimants of short-term disability benefits who exhaust their benefits, and serves as a researcher on two state-level evaluations of demonstrations designed to promote transition to postsecondary education and employment for youth with disabilities.
