The U.S. is in the midst of an epidemic of opioid overdose deaths. The common use of opioids among persons living with HIV, along with their common use of benzodiazepines, has resulted in high rates of opioid overdose among this population. This study will test the implementation of evidence-based training, mentoring, technical support, and academic detailing to encourage HIV physicians to adopt evidence-based interventions to reduce overdose risk and treat opioid addiction.
