Variation in state-run Medicaid programs provides a natural laboratory for studying how policies affect health outcomes and costs. However, the historical lack of a nationwide Medicaid dataset previously restricted Medicaid researchers’ ability to conduct cross-state studies.
CHSE received support through the OHSU and Silver Family Foundations to be among the first institutions to acquire CMS’ Transformed Medicaid Statistical Information System (T-MSIS) Analytic Files (TAF) national Medicaid dataset. The TAF dataset allows for cross-state comparisons of Medicaid policies and outcomes, offering unprecedented opportunities for national studies that until recent years were unfeasible.
Medicaid is the largest single-payer of obstetric and contraceptive services in the US. CHSE and CHSE affiliate faculty Dr. Rodriguez use TAF data to examine how variations in Medicaid policy and coverage might influence the initiation and use of effective contraception across local, state and national levels in women of reproductive age.
HOME & COMMUNITY BASED SERVICES (HCBS)
Funded by the NIH in 2021 through their highly competitive R01 program, Hyunjee Kim is currently leading a study focused on individuals aged 65+ with Alzhiemer's disease and related dementias who receive both Medicaid and Medicare services.
Dr. Kim is investigating the use of home- and community-based services (HCBS), health outcomes and health care costs, with an emphasis on potential disparities in access and use of long-term supports and services across US states with different policies.
OPIOID USE DISORDER (OUD)
In 2021, Stephan Lindner was awarded a National Institute of Health R01 grant to examine how Centers for Medicare & Medicaid Services substance use disorder waiver designs might impact outcomes for opioid users on a national level.
He and his team are partnering with OHSU Family Medicine to evaluate these waivers that allow states to test new program models to improve the care for beneficiaries with substance use disorders, including opioid use disorder.
