Reducing Stigma in People Who Inject Drugs (PWID) With HIV Using a Rapid Start Antiretroviral Therapy Intervention (ART)

This study seeks to develop an RS-ART implementation strategy by utilizing the Delphi method and interviewing experts and PWID regarding their experiences with ART. This strategy will then be pilot tested in a randomized controlled trial (Aim 3). The research will not impact the type of medication and dose prescribed, but rather, how soon providers are able to prescribe ART after diagnosis. The focus of this registration is Aim 3.

Inclusion Criteria: Patients: * Be a person with HIV, including people who inject drugs (PWID) and men who have sex with men (MSM), enrolling into ART services at one of the study's primary healthcare clinics or at Kajang Prison. PWID can include patients injecting opioids, amphetamines, or other combinations of injectable drugs. Some of these patients may be diagnosed with Opioid Use Disorder (OUD). * Be at least 18 years old. * Provide informed consent. HIV clinicians prescribing ART: * Be the HIV clinician who prescribes ART for a participating patient at one of the study sites. * Be willing to use the RS-ART protocol. * Be at least 18 years old. * Provide informed consent. Exclusion Criteria: * Pregnancy (by self-report or medical record review) * Age under 18 years * Diagnosed with, or suspected of having, an active opportunistic infection (OI) at the time of HIV care enrollment, based on standard-of-care OI screening, for whom rapid ART initiation is clinically contraindicated
