ABSTRACT

Background:

Antiretroviral therapy is highly effective in achieving HIV viral load suppression (VLS) but requires sustained engagement in care. The COVID-19 pandemic disrupted medical care, and its impact on engagement in HIV care and VLS remains unclear. Health information exchanges (HIEs) enable examination of patient care across multiple health systems. We sought to leverage HIE data to examine the effect of pandemic-related disruptions in HIV care on VLS and to explore racial/ethnic disparities in VLS. Method(s) We performed a retrospective observational study of people living with HIV (PLWH) using de-identified data from Healthix, an HIE encompassing >20 million patients and 8,000 healthcare facilities in the greater New York City (NYC) region, between 1/1/2018 and 7/14/2022. We identified PLWH based on HIV viral load (VL) tests and HIV diagnosis codes (ICD and SNOMED). We established two cohorts PLWH engaged in care in 2020 with >=1 VL test in 2019, 2020, and 2021(Group A) and PLWH not engaged in care in 2020 with >=1 VL test in 2019 and 2021 but 0 VL tests in 2020 (Group B). HIV VLS outcomes were categorized as suppressed (< 200 copies/mL) or not suppressed ( >200 copies/mL) using the last VL in 2019, first VL in 2021, and last recorded VL. We compared proportions using X2-tests and fit a group-stratified logistic regression to examine the effect of race/ethnicity on VLS. Result(s) We identified 711,358 VL tests representing 81,122 patients at 249 facilities. Of these patients, 36,199 met our definition of PLWH. Of those, 12,448 met the inclusion criteria for Group A, and 3,377 met the inclusion criteria for Group B. In 2019, Group B had a lower VLS proportion than Group A (85.9% vs 88.1%, X2 = 12.3, p< 0.0001). In 2021, this gap increased;the proportion of VLS was 80.7% in Group B and 88.0% in Group A (X2 = 121.8, p< 0.00001). Most recently, VLS in Group B had increased to 85.6%, but the inter-group gap in VLS had grown from 2.2% to 4.4%. Within both groups, Black and Hispanic patients had lower odds of VLS than white patients. This disparity was greatest in Group B when they reengaged in care in 2021, with 72.0% of Black patients (OR 0.30, 95% CI 0.22-0.42), and 79.1% of Hispanic patients (OR 0.45, 95% CI 0.31-0.63), compared to 89.5% of white patients achieving VLS. Conclusion(s) VLS remained high among PLWH who stayed engaged in care in 2020, dropped among PLWH who disengaged in care, and was lower in minoritized groups even after controlling for engagement in care.
