ABSTRACT
Background: Coronavirus Disease 2019 (COVID-19) pandemic disrupted routine program implementation worldwide with significant impact on quality and extent of technical oversight of implementation. Diverse digital reporting solutions and online meetings were some strategies designed to bridge program implementation supervision and reporting gaps worldwide. This paper evaluates usefulness and efficiency of digital solutions deployed by USAIDNigeria to ensure adequate oversight to sustain access and reporting of HIV viral load (VL) services Methods: To promote accountability and encourage peer-to-peer review and learning among USAID Implementing Partners, daily reporting via digital platforms and virtual weekly peer-review meetings were introduced. This enabled USAID team to monitor IPs' performance at health facilities and during community VL drives against set targets of 100% and 95% patient VL coverage and suppression (VLC/S) respectively. The platforms include National Laboratory Information Management System, remote sample login and Googlebased VL Status and Daily Lab Performance dashboards. This study assesses uptake of VL services and clinical outcomes in 16 states of Nigeria between October2019 through March2021 during various levels of COVID-19 lock down. Chi Square test was used to compare the pre-COVID (October2019-March2020), during lockdown (April2020-September2020) and post-COVID lockdown (October2020-March2021) performances at 95 confidence interval and < 0.05 level of significance. Result(s): Significant improvements in VL indicators were reported among eight USAID partners across 16 states. Pre-COVID, 591,906 clients on treatment were eligible for VL monitoring, 455,099 were tested and had documented VL results with a 76.9% and 89% VLC/S. During-COVID lockdown, 685,915 became eligible for VL monitoring, 531,371 had documented VL results, with 77.5% and 90% VLC/S. VLC/S increased to 93% each post-COVID lockdown, when 771,149 had documented VL out of 833,463 eligible. There was a significant increase number of clients on treatment who became eligible for VL test and had documented VL results and suppression from pre- during-COVID, and post-COVID lockdown (p=0.001) Conclusion(s): Digital solutions deployed by USAID were instrumental to sustaining service delivery with significant growth in access and efficiency to HIV VL services in 16 States in Nigeria despite impact of COVID-19. Program managers should continue to explore cost-efficient innovative approaches for program oversight.
ABSTRACT
Background: Monitoring of HIV-infected individuals on antiretroviral treatment requires periodic viral load(VL) measurements to ascertain adequate response to treatment. While plasmaVL is widely available in health facilities, it is difficult for use among key populations(KPs) due to their high mobility and sophisticated sample storage and transport requirements, which are not available for community VL sample collection. Use of Dried Blood Spot(DBS) VL measurement has shown promise as an alternative to plasma specimens for KPs. Studies to investigate the performance of DBSVL quantification against the standard plasma VL assay has proven to be within acceptable range. DBSVL was introduced for sample collection among KPs when it became difficult to safely and appropriately collect, store and transport samples during COVID-19 lockdown. This study assessed the usefulness of the use of DBSVL deployed by USAID to ensure access to HIV VL services among KPs in 7 states of Nigeria during COVID-19 lockdown Methods: To mitigate the impact of COVID-19 lockdown, virtual trainings were conducted for one-stop-shops and community VL champions of USAID partners providing KPs services in seven states of Nigeria on DBS sample collection, storage and transportation and remote test ordering was activated for service providers. Standard operating procedures and job aids were deployed to points of service and laboratory equipment were verified for DBSVL testing. VL sample collection rate(SCR), VL coverage(VLC), VL suppression(VLS), turnaround time (TAT) and cost savings for the program between March2019 and February2021 were compared using the two-sample independent t test pre-COVID (March2019- February2020) and during-COVID lockdown (March2020 -February2021) at 95 confidence interval and < 0.05 level of significance. Result(s): There was a significant increase (p< 0.05) in SCR from 73% to 94%, VLC 44% to 85%, and VLS 78% to 95% pre-COVID to during-COVID respectively despite increase in number of clients eligible for VL. However, the median TAT remained unchanged at 29 days. There was a 60% cost savings for the program due to reduction in consumables needed for sample collection and processing and convenience in sampling among KP clients. Conclusion(s): Implementation of DBSVL resulted in increases in both VLC and VLS with an improved TAT for KPs clients in seven states of Nigeria. KPs Program implementers should consider introduction of DBSVL sampling among KPs for a better VL access and clinical outcome.
