Methadone Patient Access to Collaborative Treatment (MPACT) Study

This study, called Methadone Patient Access to Collaborative Treatment (MPACT), is testing a new program designed to improve methadone treatment for opioid use disorder. The MPACT program includes training for staff on patient-centered care and trauma, as well as education about trauma symptoms. The study aims to see if this program helps patients stay in methadone treatment longer and reduces overdose events. It also looks at how staff and patient experiences with trauma might affect the program's success. The study is currently recruiting staff who provide methadone treatment services at participating clinics.
