Disparities in Integrase Inhibitor Usage in the Modern HIV Treatment Era: A Population-Based Study in a US City.

Integrase inhibitor-based (INSTI) antiretroviral therapy (ART) regimens are preferred for most people with HIV (PWH). We examined factors associated with INSTI use among PWH in San Francisco who started ART in 2009-2016. PWH who experienced homelessness were less likely, and older PWH were more likely, to use an INSTI.
