Identifying substance abuse treatment gaps in substate areas

Area of Science:

• Public Health
• Health Services Research
• Substance Abuse Epidemiology

Background:

• Uneven utilization of health services disproportionately affects disadvantaged and high-risk populations.
• Identifying and addressing substance abuse treatment gaps is crucial for public health equity.

Purpose of the Study:

• To construct and validate composite indexes for identifying substance abuse treatment gaps in Rhode Island.
• To assess the spatial distribution of treatment needs and service availability.

Main Methods:

• Developed Drug, Alcohol, and Substance Abuse Need Indexes combining multi-year rates of substance-related deaths, hospital discharges, and arrests.
• Validated the reliability and construct validity of the composite indexes.
• Used regression analysis to compare treatment admission rates with index scores.

Main Results:

• The composite indexes demonstrated reliability and validity.
• Analysis revealed specific towns and planning areas with relative gaps in substance abuse treatment services.
• Geographic disparities in treatment access were identified.

Conclusions:

• An objective, validated method for identifying treatment gaps can aid planners in ensuring equitable service access.
• Addressing identified gaps can improve treatment utilization and retention statewide.
• Reducing travel barriers is key to increasing access to care.
