ABSTRACT
Background. Substantial changes in access and delivery of primary HIV care occurred during the COVID-19 pandemic. To assess how care access changed during the COVID-19 pandemic, we estimated ED use among PWH in care 2017-2021 in the southeastern US. Methods. For each calendar year, among PWH in care in the UNC CFAR HIV Clinical Cohort (defined as having a clinic visit in the current or prior year), we estimated the percent of patients with >= 1 ED visit in a given year, overall and by age, gender, race/ethnicity, HIV viral load (VL), and CD4 count. We estimated risk ratios (RRs) comparing patient characteristics and years 2020-2021 vs. 2017-2019, using Poisson regression with generalized estimating equations to account for repeated measures. Results. Among 2129 PWH in care 2017-2021 (N=1700-1800 in each year), 57% identified as Black, 31% White, 8% Hispanic, 26% women, with median age of 47 years (IQR 35-55). During the study period, there were 3645 ED visits over 8813 person-years, a rate of 41.4 ED visits-per 100 person-years(95% CI 36.8-46.5) per 100 person-years. The 845 PWHwith at least one ED visit during the study period contributed amedian of 2 visits each (IQR1-5). The unadjusted probability of having>=1 EDvisit in a given year was higher among women vs. men (RR=1.14, 95% CI 0.99-1.32), Black vs. White PWH (1.31, 1.13-1.52), with VL >= 40 copies/mL (1.40, 1.20-1.64), and with CD4 < 200 (1.66, 1.32-2.09) or 200-349 (1.50, 1.25-1.79) vs. >= 500 cells/muL;age was not associated with ED use. Comparedwith 2017-2019, the annual probability of having>=1 EDvisit was lower in 2020-2021, with RRs of 0.83 (95% CI 0.76-0.90) in unadjusted analyses and 0.80 (95%CI 0.71-0.90) after adjusting for demographics, VL, and CD4. There was also a significant unadjusted decrease for 2020-2021 vs. 2017-2019 among women, men, PWH who were Black, White, < 40 or 50-59 years old, and with CD4 >500 (Fig. B-F, all P< 0.05). Conclusion. Among PWH in HIV care, ED use was higher among women, Black PWH, and PWH with poorly controlled HIV. ED use decreased 2020-2021 in most groups, indicating that PWH during the COVID-19 pandemic may be delaying seeking care for acute conditions, or accessing care in other ways. Work is ongoing to characterize reasons for ED visits across calendar years and examine the impact of reduced ED utilization among PWH.
ABSTRACT
Background: In 2020, COVID-19 spurred unprecedented change in the delivery of routine clinical care. The UNC OPAT program staff, previously accustomed to in-person collaboration in the hospital, became geographically distant amid North Carolina's partial shutdown starting in March 2020. Team members relied on teleworking and many OPAT clinic visits shifted to phone and video telehealth. We assessed how COVID-19 impacted our care of OPAT patients including follow-up visits and readmissions. Methods: UNC's OPAT database contains clinical and demographic information on all patients on OPAT for at least 14 days who received specialized monitoring program led by an infectious diseases (ID) pharmacist, after evaluation by an ID physician. For all OPAT courses that ended between 3/1/20 and 5/20/20 (last available data cut), we assessed the length of OPAT treatment course, readmissions, adverse events, follow-up ID clinic visits, and the method of follow up visit utilized. We compared these measurements to historical baseline data from 3/1/19 to 5/20/19. Results: During the 2020 period, 73 patients completed OPAT, with median OPAT enrollment lasting 36 days, which was similar to 2019 data (70 patients;median OPAT enrollment of 35 days). During the 2019 period, 93% of patients attended a follow up visit with an infectious diseases clinician, all of which took place in person. During the 2020 (COVID-19) period, 85% of patients attended an ID follow up visit;contrary to 2019, 42% of these visits took place in person, 45% were by phone and 13% were via a telemedicine video service. Readmission rates were similar across the two time periods (16% during COVID-19 vs 14% during 2019 comparison time period, P=0.72). Conclusion: UNC OPAT continued through the emergence of COVID-19 as an essential service for a high patient volume by adapting its care delivery and follow-up visit protocols to include virtual care options. Readmission rates for OPAT patients during COVID-19 were comparable to historical baseline data.
