The HIV Index is a validated self-report scale of engagement in HIV care previously correlated with future retention and virologic suppression. However, its performance in a monoethnic Latinx population has not been studied. We evaluated the HIV Index among Latinx persons living with HIV in the Centers for AIDS Research Network of Integrated Clinical Systems cohort and performed multivariable logistic regression to estimate its association with primary outcomes of suboptimal retention (not keeping 100% of HIV clinic appointments) and virologic suppression (HIV viral load <200 copies/mL). The mean Index score was 4.5 (standard deviation 0.6) in both analytic samples, indicative of feeling well-engaged. Higher Index scores were associated with lower odds of suboptimal retention (OR = 0.12, 95% CI [0.03, 0.54], p = .005), however, there was no association between Index score and virologic suppression. The HIV Index is useful for assessing engagement and retention among Latinx PLWH in routine care.
