A total of 1562 people who inject drugs who initiated MOUD for the first time at an ICC between 1 January 2018 and 31 December 2018 were included in this study. Median age was 26 years, 98% were male and 22% were living with HIV.<h4>Measurements</h4>Daily Addiction (Abingdon, England)Trajectories of medication for opioid use disorder and their impact on HIV testing among people who inject drugs in India: A longitudinal assessment of clinic-based data.PMC11907330R01 DA049301R01DA041034K23DA057151R01 DA041034P30AI094189K23 DA0571511P30AI094189P30 AI094189Gunaratne MPSrikrishnan AKLucas GMAnand SVasudevan CKMcFall AMGanapathi LSolomon SSMehta SHfalseTrajectories of medication for opioid use disorder and their impact on HIV testing among people who inject drugs in India: A longitudinal assessment of clinic-based data.<h4>Aims</h4>The aim of this study was to identify longitudinal trajectories of medication for opioid use disorder (MOUD) use throughout 1 year following MOUD initiation and to examine the association of trajectory membership with HIV testing among people who inject drugs in India.<h4>Design, setting and participants</h4>The study comprised group-based trajectory modeling using longitudinal clinic-based MOUD use data, set in seven Indian cities with integrated care centers (ICC) delivering MOUD, predominantly buprenorphine, in 2018-2019.
