Linkage to care (LTC) and initiation of antiretroviral therapy (ART) are key components in the longitudinal care cascade for people living with HIV. Many strategies to optimize these stages of HIV care have been implemented, though there is a paucity of analyses comparing the outcomes of these efforts in low- and middle-income countries. We conducted a systematic review of studies assessing interventions along all stages of the HIV care continuum published between 2008 and 2020. A comprehensive search strategy reviewed five electronic databases to capture studies assessing HIV testing, LTC, ART initiation, ART adherence, and viral suppression. Of the 388 articles that met the inclusion criteria, 78 described interventions for improving LTC/ART initiation. Efforts focused on empowering patients through integrative approaches generally yielded more substantive results compared to provider-initiated non-adaptive LTC interventions or cash incentives. Specifically, tailoring care and incorporating ART initiation into existing infrastructures, such as maternal clinics, had a high impact across settings. Moreover, strategies such as home-based HIV counseling and testing (HBHCT) appear to be most effective when implemented in tandem with other approaches including motivational counseling and point-of-care CD4 testing.
