Retention of people who inject drugs enrolled in a 'medications for opioid use disorder' (MOUD) programme in Uganda.

Our study demonstrates acceptable 12-month retention rates for people who inject drugs, comparable to previous studies done in both developing and developed countries. Sustaining and improving retention may require enhanced scaling up of MOUD dose to an optimal level in the first 14 days and reducing the distance between participant locale and MOUD clinics.
