Effects of Multimonth Dispensing on Viral Suppression and Continuity in Treatment Among Children Living With HIV Aged 2-9 Years: A Cohort Study in Western Kenya.

BACKGROUND: In Kenya, of the 82,000 children living with HIV, only 59% are receiving ART and 67% are virally suppressed. Early in the COVID-19 pandemic, the Ministry of Health recommended 3 multimonth dispensing (3MMD) of ART to all people living with HIV, including children. This study assesses the association between 3 MMD and clinical outcomes among children in Western Kenya. SETTINGS: and Methods: We conducted a retrospective cohort study using routinely collected deidentified patient-level data from 43 facilities in Kisii and Migori Counties. The study included children aged 2-9 years who had been previously initiated on ART and sought HIV services between March 01, 2020, and March 30, 2021. We used generalized linear models with Poisson regression models to assess the association between MMD on retention at 6 months and viral suppression (<1000 copies/mL). RESULTS: Among the 963 children, 65.2% were aged 5-9 years and 50.7% were female patients. Seventy-eight percent received 3MMD at least once during the study period. Children who received 3MMD were 12% (adjusted risk ratio [aRR] 1.12, 95% CI: 1.01 to 1.24) more likely to be retained and 22% (aRR 1.22, 1.12 to 1.34) more likely to be virally suppressed than those on <3MMD. When stratified by viral suppression at entry, the association between 3MMD and retention (aRR 1.22, 95% CI: 1.02 to 1.46) and viral suppression (aRR 1.76, 95% CI: 1.30-2.37) was significant among individuals who were unsuppressed at baseline. CONCLUSIONS: 3MMD was associated with comparable or improved HIV health outcomes among children.

Impact of enhanced adherence counselling on viral re-suppression among adolescents and young persons with persistent viremia.

OBJECTIVE: Kenya ART guidelines recommend three sessions of enhanced adherence counselling (EAC) following detectable viral load (VL). The objective of this study was to assess completion of EAC sessions and factors associated with viral re-suppression amongst adolescents and young persons (AYPs) with persistent viremia in Western Kenya. METHODS: A retrospective analysis of routinely collected data abstracted from VL registers was done. AYP with persistent viremia (consecutive VL ≥ 1,000 copies/ml) between October 2017 to September 2019 were followed for 12 months; those with >1 follow-up VL results were analyzed. EAC was satisfactory if ≥3 sessions attended, barriers identified and addressed. Morisky scores 0 and ≥1 indicated optimal and sub-optimal adherence respectively. Logistic regression models were used to assess predictors of viral load suppression (VLS). RESULTS: Of 124 AYPs with persistent viremia, 118(95.2%) had documented follow up VL results and 119(96.0%) completed three EAC sessions. Overall, 55(47%) clients re-suppressed during the study period. AYPs who had satisfactory EAC sessions had higher odds of achieving VLS (odds ratio [OR] = 3.7, 95% confidence interval [CI]: 1.6-8.1). Similarly, AYPs with an optimal adherence had eight times (OR = 8.1, 95%CI: 3.5-18.5) higher odds of achieving VLS, and those who were suppressed at 6 months post ART initiation had higher odds of achieving VLS at 12-months (OR = 2.5, 95%CI:1.1-5.8). CONCLUSION: Satisfactory EAC sessions and optimal ART adherence was strongly associated with viral re-suppression among AYPs with persistent viremia. Continued support to EAC intervention is critical to improve treatment outcome among AYP living with HIV.

Factors associated with enrollment into differentiated service delivery model among adults with HIV in Kenya.

INTRODUCTION: Differentiated service delivery (DSD) such as multimonth dispensing (MMD) aims to provide client-centered HIV services, while reducing the workload within health facilities. We assessed individual and facility factors associated with receiving more than three MMD and switching from ≥3MMD back to <3MMD in Kenya. METHODS: We conducted a retrospective cohort study of clients eligible for DSD between July 2017 and December 2019. A random sample of clients eligible for DSD was selected from 32 randomly selected facilities located in Nairobi, Kisii, and Migori counties. We used a multilevel Poisson regression model to assess the factors associated with receiving ≥3MMD, and with switching from ≥3MMD back to <3MMD. RESULTS: A total of 3501 clients eligible for ≥3MMD were included in our analysis: 1808 (51.6%) were receiving care in Nairobi County and the remaining 1693 (48.4%) in Kisii and Migori counties. Overall, 65% of clients were enrolled in ≥3MMD at the time of entry into the cohort. In the multivariable model, younger age (20-24; 25-29; 30-34 vs. 50 or more years) and switching ART regimen was significantly associated with a lower likelihood of ≥3MMD uptake. Factors associated with a higher likelihood of enrollment in ≥3MMD included receiving DTG vs. EFV-based ART regimen (aRR: 1.10; 95% confidence interval: 1.05-1.15). CONCLUSION: Client-level characteristics are associated with being on ≥3MMD and the likelihood of switching from ≥3MMD to <3MMD. Monitoring DSD enrollment across different populations is critical to successfully implementing these models continually.

Scale-up of HIV index testing in an urban population: Experiences and achievements from Nairobi County, Kenya.

OBJECTIVE: To describe the implementation strategies of the index testing program across Nairobi County in Kenya, assess outcomes along the HIV index testing cascade (acceptance, elicitation ratio, HIV positivity and linkage to treatment), and assess annual changes along the HIV index testing cascade during the first 2 years of implementation. METHODS: Retrospective analysis of programmatic aggregate data collected from October 2017 to September 2019 after the roll-out of index testing services in 48 health facilities in Nairobi County. Proportions and ratios were calculated for acceptance, elicitation ratio, testing uptake and HIV positivity. We compared these outcomes between years using a chi-squared test, Fisher's exact test or Wilcoxon sign test, and we assessed trends using the Mann-Kendall test. RESULTS: Testing among eligible partners increased from 42.4% (1471/3470) to 74.9% (6114/8159) in the general population, and the positivity yield remained high across both years (25.2% in year 1 and 24.1% in year 2). Index testing positivity yield remained significantly higher than other testing modalities (24.3% vs. 1.3%, p < 0.001). The contribution of index testing services to the total number of HIV-positive individuals identified increased from 7.5% in the first year to 28.6% in the second year (p < 0.001). More men were tested, but the positivity yield was higher among women (30.0%) and those aged 50 years or older (32.4%). Testing eligible partners in key populations (KPs) decreased from 52.4% (183/349) to 40.7% (109/268) (p = 0.674); however, the HIV positivity yield increased from 8.6% to 23.9% (p < 0.001) by the second year of implementation. The HIV positivity yield from index testing remained higher than other testing modalities (14% vs. 0.9%, p < 0.001) for KPs. CONCLUSION: Index testing was well-accepted and effective in identifying individuals living with HIV in a Kenyan urban setting across both general populations and KPs. Ongoing adaptations to the strategies deployed as part of index testing services helped improve most of the outcomes along the index testing cascade.

Making voluntary medical male circumcision services sustainable: Findings from Kenya's pilot models, baseline and year 1.

Voluntary medical male circumcision is a crucial HIV prevention program for men in sub-Saharan Africa. Kenya is one of the first countries to achieve high population coverage and seek to transition the program to a more sustainable structure designed to maintain coverage while making all aspects of service provision domestically owned and implemented. Using pre-defined metrics, we created and evaluated three models of circumcision service delivery (static, mobile and mixed) to identify which had potential for sustaining high circumcision coverage among 10-14-year-olds group, a historically high-demand and accessible age group, at the lowest possible cost. We implemented each model in two distinct geographic areas, one in Siaya and the other in Migori county, and assessed multiple aspects of each model's sustainability. These included numerical achievements against targets designed to reach 80% coverage over two years; quantitative expenditure outcomes including unit expenditure plus its primary drivers; and qualitative community perception of program quality and sustainability based on Likert scale. Outcome values at baseline were compared with those for year one of model implementation using bivariate linear regression, unpaired t-tests and Wilcoxon rank tests as appropriate. Across models, numerical target achievement ranged from 45-140%, with the mixed models performing best in both counties. Unit expenditures varied from approximately $57 in both countries at baseline to $44-$124 in year 1, with the lowest values in the mixed and static models. Mean key informant perception scores generally rose significantly from baseline to year 1, with a notable drop in the area of community engagement. Consistently low scores were in the aspects of domestic financing for service provision. Sustainability-focused circumcision service delivery models can successfully achieve target volumes at lower unit expenditures than existing models, but strategies for domestic financing remain a crucial challenge to address for long-term maintenance of the program.
