We abstracted electronic medical records for patients ≥ 10 years, initiated on ART April 1, 2019 – June 30, 2021, and with a 6- or 12-month viral load (VL) result. We categorized participants in the MMD group to see if they received antiretroviral treatment (ART) for ≥ 84 days at any visit within 6 months of ART initiation. We consider cut-offs for viral suppression at 50 copies/mL. The period when the VL was performed was classified as pre-COVID-19 (before April 1, 2020) or during the COVID-19 pandemic. We estimated relative risks (RR) by comparing the unsuppressed proportion of those on MMD to those not on MMD, adjusted for age, gender, and COVID-19 period.Results: Overall, 19,859 participant records were abstracted. Median age was 33 years, 64% were female, 91% were started on a dolutegravir (DTG)-based regimen, and 65% were on MMD. Overall, 15,259 (77%) participants were followed for ≥ 6 months, 4136 (27%) had a VL at 6 months and 3640 (24%) had a VL at 12 months after ART initiation. A slightly higher proportion of patients on MMD had undetectable VL levels at 6 months (65% vs 58%) and 12 months (66% vs 62%). In the adjusted analysis, we found no significant differences in undetectable VL at 6 months and 12 months between newly enrolled patients on MMD and those not on MMD. Those on Protease inhibitor-based regimen had 54% lower likelihood of undetectable VL compared to those on DTG-based regimen.Conclusion: MMD does not result in poorer viral suppression among newly enrolled patients.Keywords: HIV, differentiated service delivery, PLHIV, Nigeria

During the COVID-19 pandemic, HIV programs scaled up differentiated service delivery (DSD) models for people living with HIV (PLHIV). We evaluated the effects of COVID-19 on HIV service delivery and viral suppression in facilities in Northern Nigeria, and determined factors associated with viral suppression among adolescents and adults. We analysed a cross-sectional survey data from facility heads, and retrospective, routinely collected patient data from 63 facilities for PLHIV ≥10 years old in care between April 2019-March 2021, defining study periods as "pre-COVID-19" (before April 2020) and "during COVID-19" (after April 2020). For the pre-COVID and the COVID-19 periods we compared uptake of antiretroviral therapy (ART) refills of ≥3 months (MMD3), and ≥6 months (MM6), missed appointments, viral load (VL) testing, VL testing turnaround time (TAT) and viral suppression among those on ART for ≥6 months using two proportions Z-test and t-tests. We fit a multivariable logistic regression model to determine factors associated with maintaining or achieving viral suppression. Of 84,776 patients, 58% were <40 years, 67% were female, 55% on ART for >5 years, 93% from facilities with community-based ART refill, a higher proportion were on MMD3 (95% versus 74%, p<0.001) and MMD6 (56% versus 22%, p<0.001) during COVID-19 than pre-COVID-19, and a higher proportion had VL testing during COVID-19 (55,271/69,630, [84%]) than pre-COVID-19 (47,747/68,934, [73%], p<0.001). Viral suppression was higher during COVID-19 pandemic compared to the pre-COVID era (93% [51,196/55,216] versus 91% [43,336/47,728], p<0.001), and there was a higher proportion of missed visits (40% [28,923/72,359] versus 39% [26,304/67,365], p<0.001) and increased VL TAT (mean number of days: 38 versus 36, p<0.001) during COVID-19 pandemic and pre-COVID period respectively. Factors associated with maintaining or achieving suppression during COVID-19 were receiving MMD3 and MMD6 refills (OR: 2.8 [95% CI: 2.30-3.47] and OR: 6.3 [95% CI: 5.11-7.69], respectively) and attending clinics with community-based ART refill (OR: 1.6 [95% CI: 1.39-1.87]). The program in Northern Nigeria demonstrated resilience during the COVID-19 pandemic and adoption of MMD had a positive impact on HIV care. Though VL TAT and missed clinic visits slightly increased during the pandemic, VL testing improved and viral suppression moved closer to 95%. Adoption of MMD and community-based models of care at scale are recommended for future pandemic preparedness., Competing Interests: Ezekiel James is employed by the United States Agency for International Development mission in Nigeria and supervised the study.

Differentiated service delivery (DSD) and multi-month dispensing (MMD) of antiretroviral therapy (ART) have improved treatment adherence and viral suppression among people living with HIV (PLHIV), and service delivery efficiency. We assessed the experiences of PLHIV and providers with DSD and MMD in Northern Nigeria. We conducted in-depth interviews (IDI) with 40 PLHIV and 6 focus group discussions (FGD) with 39 health care providers across 5 states, exploring their experiences with 6 DSD models. Qualitative data were analyzed using NVivo®1.6.1. Most PLHIV and providers found the models acceptable and expressed satisfaction with service delivery. The DSD model preference of PLHIV was influenced by convenience, stigma, trust, and cost of care. Both PLHIV and providers indicated improvements in adherence and viral suppression; they also raised concerns about quality of care within community-based models. PLHIV and provider experiences suggest that DSD and MMD have the potential to improve patient retention rates and service delivery efficiency., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2023 Semo et al.

Background: Few studies in sub-Saharan Africa have assessed the impact of multimonth dispensing (MMD) of antiretroviral therapy (ART) and dolutegravir (DTG) beyond clinical trials among children with HIV (CWHIV). We assessed the effect of the 2 interventions on achieving undetectable viral load (VL) among CWHIV in the age group of 0-15 years in Nigeria., Methods: We used longitudinal routine records and cross-sectional survey data from caregivers of a subsample of children. VLs were considered suppressed at <1000 copies/mL and undetectable at <50 copies/mL. Multimonth dispensing (MMD) was defined as ART refill for >84 days. The effect of MMD and DTG on VL levels and associations between social factors and VL were estimated using generalized linear models, reporting adjusted relative risks/prevalence ratios and 95% confidence intervals (CIs)., Results: Of 2490 CWHIV, 52% were male, with a median age of 10 years (interquartile ranges: 6-13) and a median duration on ART of 4.6 years (interquartile ranges: 2.8-7.1). Overall, 73% were on DTG and 55% received MMD. At baseline, 63% were suppressed, while 79% and 56% were suppressed and undetectable in their last VL, respectively. We found no differences in undetectable VL between those on MMD and not on MMD (adjusted relative risks: 1.05 [95% CI: 0.94-1.18]) and between those on DTG and not on DTG (1.07 [0.92-1.25]). In secondary analyses, poor adherence and being in a support group were associated with a lower likelihood of undetectable VL (adjusted prevalence ratios: 0.85 [95% CI: 0.74-0.96] and 0.81 [0.68-0.96], respectively)., Conclusion: MMD did not compromise treatment outcomes for CWHIV. Poor adherence, however, remains a barrier to achieving treatment targets., Competing Interests: Authors declare no conflict of interest., (Copyright © 2023 The Author(s).
