JOINT REPLACEMENT

Hip/knee replacements are the most common inpatient surgeries for Medicare beneficiaries. Comprehensive Care for Joint Replacement (CJR) — Medicare's first mandatory bundled payment program— reflects a national move towards value-based payment. CHSE provides research assessing whether CJR affects disparities in joint replacement care.

HOME & COMMUNITY BASED SERVICES (HCBS)

Home and community based services (HCBS) provide opportunities for Medicaid beneficiaries to receive services in their own home or community rather than institutions or other isolated settings. These programs serve a variety of targeted populations groups, such as people with intellectual or developmental disabilities, physical disabilities, and/or mental illnesses.

In 2021, Hyunjee Kim received a National Institute of Health R01 grant 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 HCBS, health outcomes and health care costs for this population, with an emphasis on potential disparities in access and use of long-term supports and services across U.S. states with different policies.
