People living in states with comprehensive mental health parity laws did not experience improved outcomes overall compared with people in states with less investment in mental health, according to a
report in
Psychiatric Services.
Why It’s Relevant
Despite enactment of the Mental Health Parity and Addiction Equity Act and the Affordable Care Act along with increased state expenditures on mental health, many Americans still face difficulties in accessing mental health and substance use disorder services. Previous research has found that states with comprehensive parity implementation have a robust mental health workforce and higher spending—but do these system-level improvements translate to better patient care?
By the Numbers
- Researchers compared five patient-level outcomes across the top 10 and bottom 10 states for per capita state mental health agency (SMHA) expenditures: treatment receipt, unmet need, cost-related barriers to care, drug overdose mortality, and suicide mortality.
- In states with high SMHA expenditures, 19.7% of people with frequent mental illness experienced cost-related barriers to care compared with 24.2% in states with low expenditures.
- In the seven states with comprehensive parity coverage (all in the top 10 SMHA), 18.8% of people experienced cost-related barriers to care compared with 23.6% of people in the 13 states with more limited coverage.
- There were no statistical differences across the other four outcomes between states with the highest and lowest SMHA expenditures or between states with comprehensive and limited parity coverage.
The Other Side
This analysis was limited to 20 states, which may have reduced the statistical power needed to detect differences. Additionally, client access and behavioral health measures were derived from multiple data sources and years, which may have introduced inconsistencies in reporting.
Takeaway Message
The findings underscore the need to examine mental health workforce variables beyond size, such as insurance network participation and geographic inequities at county/community levels. Future research could focus on identifying the intermediary elements that may be de-linking the system-level benefits of high parity and public mental health spending from the individual experience, such as reimbursement structure, wait times, or geographic access.
