Changes In US spending on Mental Health And Substance Abuse Treatment, 1986-2005, and implications for policy

Area of Science:

• Health Economics
• Public Health Policy
• Mental Health Services Research

Background:

• The United States allocated $135 billion to mental health and substance abuse treatments in 2005, representing 1.07% of the Gross Domestic Product (GDP).
• Understanding historical spending trends (1986-2005) is crucial for evaluating past policies and forecasting future investment in mental health and substance abuse care.
• Mental health medication expenditures were a primary driver of overall spending in previous years.

Purpose of the Study:

• To analyze trends in US spending on mental health and substance abuse treatments from 1986 to 2005.
• To identify key factors influencing changes in healthcare expenditure for mental health and substance abuse.
• To provide context for evaluating the impact of upcoming healthcare reforms and policies.

Main Methods:

• Estimation of treatment spending for mental health and substance abuse from 1986 to 2005.
• Analysis of growth rates in overall spending and specific expenditure categories, such as mental health medications.
• Examination of the share of total health spending and Medicaid's contribution to mental health spending over time.

Main Results:

• The growth rate of spending on mental health medications, a significant expenditure driver, experienced a substantial decline.
• Overall spending on mental health and substance abuse grew at a rate slower than the GDP in 2004 and 2005.
• The proportion of total health spending dedicated to mental health and substance abuse decreased during the study period.
• Medicaid's share of total mental health spending increased from 17% in 1986 to 28% in 2005.

Conclusions:

• The deceleration in medication spending growth has led to a slower overall growth rate for mental health and substance abuse expenditures relative to GDP.
• Policy changes, including the Affordable Care Act, federal parity laws, and Medicaid expansion, are anticipated to influence future access and spending patterns.
• Accurate spending estimates are vital for assessing the effectiveness of mental health and substance abuse treatment policies.
