Abstract
BACKGROUND: Opioid use results in higher healthcare utilization and costs, particularly among those with co-occurring mental health disorders. Presumably, effective treatment would result in a reduction in healthcare utilization and costs. To date, research has not examined this question. As such, the purpose of this study was to estimate and compare pre- and post-treatment healthcare utilization and costs for individuals receiving residential integrated treatment for co-occurring mental health and opioid use disorders. METHODS: A single-group, repeated measures design was used to examine changes in pre- and post-treatment healthcare utilization and costs among a sample of individuals with co-occurring mental health and opioid use disorders who received residential, integrated treatment. RESULTS: Significant reductions in emergency rooms visits, inpatient admissions, and resulting costs were observed in the six months following treatment. CONCLUSIONS: Residential, integrated treatment of co-occurring mental health and opioid use disorders can significantly decrease both utilization and cost of healthcare among opioid users with co-occurring mental health disorders.
