BACKGROUND
The HIV epidemic has revealed considerable disparities in health among sexual and gender minorities of color within the Unites States, disproportionately affecting men who have sex with men (MSM) and trans women. Social inequities further disadvantage those with intersectional identities through homophobia, anti-trans discrimination, and racism, shaping not only those at-risk for HIV infection, but also HIV prevention and care outcomes. Digital interventions have great potential to address barriers and improve HIV care among MSM and trans women; however, efficacy of digital HIV care interventions vary and need further examination.
OBJECTIVE
This study assessed 12-month efficacy of a 6-month digital HIV care navigation intervention among young people living with HIV (YPLWH) in San Francisco We examined dose-response relationships between intervention exposure (e.g. text messaging) and viral suppression and mental health. Health electronic navigation (eNavigation or eNav) is a 6-month, text message-based, digital HIV care navigation intervention, in which YPLWH are connected to their own HIV care navigator through text messaging to improve engagement in HIV primary care.
METHODS
This study had a single-arm, prospective, pre-post design. Eligibility criteria for the study included: identifying as a man who has sex with men or a trans woman; being between the ages of 18 and 34 years; and being newly diagnosed with HIV or not being engaged/retained in HIV care or having a detectable viral load. We assessed and analyzed sociodemographic, intervention exposure, and HIV care and mental health outcome data for participants who completed the 6-month Health eNav intervention. We assessed all outcomes using generalized estimating equations (GEE) to account for within-subjects correlation, and marginal effects of texting engagement on all outcomes were calculated over the entire 12-month study period. Finally, we specified an interaction between texting engagement and time to evaluate the effects of texting engagement on outcomes.
RESULTS
Over the entire 12-month study period showed that every one-text increase in engagement was associated with an increased odds of undetectable viral load (adjusted odds ratio, aOR = 1.01, 95% CI = 1.00 – 1.02, p = 0.03). We found that mean negative mental health experiences decreased significantly at 12 months compared to baseline for every one-text increase in engagement (coefficient on interaction term: 0.97, 95%CI = 0.96-0.99, p < 0.01).
CONCLUSIONS
Digital care navigation interventions like Health eNavigation may be a critical component in the health delivery service system as the digital safety net for those whose social vulnerability is exacerbated in times of crisis, disasters, or global pandemics due to multiple social inequities. We found that increased engagement in a digital HIV care navigation intervention helped to improve viral suppression and mental health – intersecting, co-morbid conditions – 6-months after the intervention concluded. Digital care navigation may be a promising, effective, sustainable, and scalable intervention.
