BLD: Below limit of detection for the assay being used; LTC: linked to care; EIC: engaged in care; RIC: retained in care; LTC OW: linkage to care outreach worker, also referred to as LTC or linkage coordinator; ATN: Adolescent Medicine Trials Network for HIV/AIDS Interventions; ART: antiretroviral therapy
Substances assessed included alcohol, barbiturates, club drugs, hallucinogens, inhalants, sedative hypnotics, amphetamines, cannabis, cocaine, heroin, methadone, other opiates and street hormones.
Care intervals along the HIV Care Continuum were defined for LTC: a clinical visit attended no later than 42 days after referral for linkage; EIC: at least one additional clinical visit attended no later than 16 weeks after LTC; RIC: at least one additional clinical visit attended no later than 52 weeks after EIC; and, *Post-RIC: a second clinical visit attended within 52 weeks after EIC, if the RIC visit occured early in the interval.
LTC = Linked to Care; VL = Viral Load; STI = Sexually transmitted infection
