NIH-funded research Oregon Health & Science University · NIH-11172537

This project looks at whether new Medicaid rules that let states pay for psychiatric hospitals and crisis services help adults with serious mental illness and children with serious emotional disturbances get better care and have fewer emergency visits or suicide-related harms.

What this research studies

If you or a family member has serious mental health needs, this work compares places that used a new Medicaid waiver to fund inpatient psychiatric beds and crisis services with places that did not. The researchers will analyze hospital, emergency department, and Medicaid data across states and over time to see how service use, ED boarding, and suicide-related behaviors changed after waiver adoption. They will also look at differences in how states implemented the waivers to find which approaches work best. The goal is to identify policies that improve access to crisis care and reduce harms for people covered by Medicaid.

Who could benefit from this research

Good fit: The most relevant people are Medicaid enrollees with serious mental illness (adults) or serious emotional disturbances (children), especially those who use emergency departments or need inpatient psychiatric care.

Not a fit: People who are uninsured or have only private insurance, or who live in states that do not implement these waivers, may not see direct benefits from the waiver-driven changes this project studies.

Why it matters

Potential benefit: If successful, the findings could support policy changes that increase access to crisis and inpatient mental health care and reduce emergency visits and suicide-related harms for people on Medicaid.

How similar studies have performed: Early reports from some state evaluations show increased bed capacity or expanded crisis services, but evidence on effects on emergency use and suicide-related outcomes is limited and mixed.
