Cost Savings from a Navigator Intervention for Repeat Detoxification Clients

Area of Science:

• Health Services Research
• Substance Use Disorder Treatment
• Health Economics

Background:

• Clients with substance use disorders (SUD) often experience multiple detoxification admissions without transitioning to formal SUD treatment.
• High costs and ineffective outcomes of repeated detox admissions are a significant concern for US health insurers.
• Navigator programs, similar to those used for other diseases, aim to guide high-risk patients through the healthcare system.

Purpose of the Study:

• To evaluate the impact of a navigator intervention on healthcare spending for individuals with multiple SUD detox admissions.
• To determine if spending effects varied by intervention arm (navigator alone vs. navigator with incentives).
• To assess the net savings to payers after accounting for intervention implementation costs.

Main Methods:

• A navigator intervention using Recovery Support Navigators (RSNs) was implemented within the Massachusetts Medicaid population.
• Clients were offered RSNs to connect them with SUD treatment and community resources.
• Multivariate analyses of claims and administrative data assessed healthcare spending and payer net savings.

Main Results:

• Health care spending growth was 1.6 percentage points lower among intervention-enrolled members compared to controls, indicating gross savings of $68 per member per month.
• Net savings were estimated at $57 per member per month after deducting intervention costs.
• The intervention was associated with a shift in healthcare service utilization from acute to less acute settings.

Conclusions:

• Navigator-based interventions show potential for reducing healthcare costs associated with repeat detoxification admissions for SUD.
• The intervention demonstrated favorable effects on initiating SUD treatment, suggesting a shift towards more effective care.
• Payers may consider experimenting with navigator interventions to decrease healthcare costs and improve the lives of SUD patients.
