This is an academic paper that examined initiation of medications for opioid use disorder (MOUD) based on waiting time for an appointment at a low threshold addiction clinic in Boston. Patients who were able to get same-day or next-day appointments were more likely to arrive at their appointments compared with those who had to wait longer. This finding highlights that hospitals should have immediate access to MOUD, such as access a bridge clinic co-located at the hospital, to increase engagement in MOUD.
