Veterans' Service Utilization Patterns After Alcohol and Opioid Detoxification in VHA Care.

OBJECTIVE

This study aimed to examine detoxification-related service utilization in the Veterans Health Administration (VHA).

METHODS

VHA data for 266,908 patients were used to examine rates and predictors of receiving detoxification, attending post-detoxification appointments, and entering specialty treatment. Multilevel, mixed-effects logistic regressions were used to examine associations between patient and facility characteristics and service utilization.

RESULTS

Nationally, 8.0% of VHA patients with alcohol or opiate dependence received detoxification in fiscal year 2013 (facility range=.1%-20.4%); 43.1% of detoxified patients received follow-up (11.1%-76.4%), and 49.9% entered specialty treatment (13.0%-77.2%). In adjusted analyses, detoxification was more likely among male, younger, white, and homeless patients with documented alcohol or opiate disorders and comorbid general medical conditions but without previous addiction treatment. Detoxification was also more likely in facilities with fewer vacant addiction therapist positions. Follow-up and specialty treatments were more likely among younger, healthier homeless patients with previous addiction treatment and a documented alcohol use disorder.

CONCLUSIONS

Detoxification-related service utilization was highly variable across the VHA. Interventions are needed to optimize use.
