Cost-effectiveness and budget impact of decentralising childhood tuberculosis diagnosis in six high tuberculosis incidence countries: a mathematical modelling study.

Background: The burden of childhood tuberculosis remains high globally, largely due to under-diagnosis. Decentralising childhood tuberculosis diagnosis services to lower health system levels could improve case detection, but there is little empirically based evidence on cost-effectiveness or budget impact.

Methods: In this mathematical modelling study, we assessed the cost-effectiveness and budget impact of decentralising a comprehensive diagnosis package for childhood tuberculosis to district hospitals (DH-focused) or primary health centres (PHC-focused) compared to standard of care (SOC).

Isoniazid preventive therapy completion between July-September 2019: A comparison across HIV differentiated service delivery models in Uganda.

Background: Tuberculosis (TB) remains the leading cause of death among people living with HIV (PLHIV). To prevent TB among PLHIV, the Ugandan national guidelines recommend Isoniazid Preventive Therapy (IPT) across differentiated service delivery (DSD) models, an effective way of delivering ART. DSD models include Community Drug Distribution Point (CDDP), Community Client-led ART Delivery (CCLAD), Facility-Based Individual Management (FBIM), Facility-Based Group (FBG), and Fast Track Drug Refill (FTDR).

Effect of the "universal test and treat" policy on the characteristics of persons registering for HIV care and initiating antiretroviral therapy in Uganda.

We examined the effect of the Universal Test and Treat (UTT) policy on the characteristics of people living with HIV (PLHIV) at enrolment in HIV care and initiation of antiretroviral therapy (ART) in Uganda using data from 11 nationally representative clinics of The AIDS Support Organisation (TASO). We created two retrospective PLHIV cohorts: pre-UTT (2004-2016), where ART initiation was conditional on CD4 cell count and UTT (2017-2022), where ART was initiated regardless of World Health Organisation (WHO) clinical stage or CD4 cell count. We used a two-sample test of proportions and Wilcoxon rank-sum test to compare proportions and medians, respectively, between the cohorts.

Regulation of community advisory boards during conduct of clinical trials in Uganda: a qualitative study involving stakeholders.

Background: Community advisory structures such as Community Advisory Boards (CABs) play an important role of helping researchers to better understand the community at each phase of the clinical trial. CABs can be a source of accurate information on the community, its perception of proposed research and may identify factors that make community members vulnerable to the problem under investigation. Although CABs help to build mutually beneficial relationships between the researcher(s) and the communities in which the clinical trial is being implemented, effective engagement would require ethical guidance and regulatory oversight.

Limited Impact of First-Line Drug Resistance Mutations on Virologic Response Among Patients Receiving Second-Line Antiretroviral Therapy in Rural Uganda.

Background: Delayed detection of ART failure in settings without access to viral load (VL) monitoring has been hypothesized to lead to suboptimal response to second-line therapy due to accumulated drug resistance mutations (DRMs). We tested this hypothesis in a program setting in rural Uganda.

Methods: From June 2012 to January 2014, we enrolled participants receiving nonnucleoside reverse transcriptase inhibitor-based first-line ART for ≥4 years, without access to VL monitoring.

Mobile tablets for real-time data collection for hospital-based birth defects surveillance in Kampala, Uganda: Lessons learned.

Sustainable birth defects surveillance systems provide countries with estimates of the prevalence of birth defects to guide prevention, care activities, and evaluate interventions. We used free and open-source software (Open Data Kit) to implement an electronic system to collect data for a hospital-based birth defects surveillance system at four major hospitals in Kampala, Uganda. We describe the establishment, successes, challenges, and lessons learned from using mobile tablets to capture data and photographs.

Effect of universal test and treat on retention and mortality among people living with HIV-infection in Uganda: An interrupted time series analysis.

Background: Few studies have analysed the effect of HIV universal test and treat (UTT) on retention and mortality among people living with HIV (PLHIV) in routine care. We examined six-month retention and mortality at 11 health facilities (HFs) run by a large NGO, The AIDS Support Organisation (TASO), before and after UTT.

Methods: We used a quasi-experimental study using patient data extracted from 11 TASO HFs.

Knowledge, attitudes and practices on childhood TB among healthcare workers.

Increasing childhood TB case detection requires the deployment of diagnostic services at peripheral healthcare level. Capacity and readiness of healthcare workers (HCWs) are key to the delivery of innovative approaches. In 2019, HCWs from five district hospitals (DHs) and 20 primary healthcare centres (PHCs) in Cambodia, Cameroon, Cote d´Ivoire, Sierra Leone and Uganda completed a self-administered knowledge-attitudes-practices (KAP) questionnaire on childhood TB.

Capacity of community advisory boards for effective engagement in clinical research: a mixed methods study.

Background: Community engagement is a key component in health research. One of the ways health researchers ensure community engagement is through Community Advisory Boards (CABs). The capacity of CABs to properly perform their role in clinical research has not been well described in many resource limited settings.

Durability of non-nucleotide reverse transcriptase inhibitor-based first-line ART regimens after 7 years of treatment in rural Uganda: A prospective cohort study.

Most antiretroviral therapy (ART) programs in resource-limited settings have historically used non-nucleotide reverse transcriptase inhibitor (NNRTI)-based regimens with limited access to routine viral load (VL) testing. We examined the long-term success of these regimens in rural Uganda among participants with 1 measured suppressed VL.We conducted a prospective cohort study of participants who had been on NNRTI-based first-line regimens for ≥4 years and had a VL <1000 copies/mL at enrollment in Jinja, Uganda.

"Our Choice" improves use of safer conception methods among HIV serodiscordant couples in Uganda: a cluster randomized controlled trial evaluating two implementation approaches.

Background: Safer conception counseling (SCC) to promote the use of safer conception methods (SCM) is not yet part of routine family planning or HIV care. Guidelines for the use of SCM have been published, but to date there are no published controlled evaluations of SCC. Furthermore, it is unknown whether standard methods commonly used in resource constrained settings to integrate new services would be sufficient, or if enhanced training and supervision would result in a more efficacious approach to implementing SCC.

Serological evidence of Rift Valley fever virus infection among domestic ruminant herds in Uganda.

Background: Prior to the first recorded outbreak of Rift Valley fever (RVF) in Uganda, in March 2016, earlier studies done until the 1970's indicated the presence of the RVF virus (RVFV) in the country, without any recorded outbreaks in either man or animals. While severe outbreaks of RVF occurred in the neighboring countries, none were reported in Uganda despite forecasts that placed some parts of Uganda at similar risk. The Ministry of Agriculture, Animal Industry and Fisheries (MAAIF) undertook studies to determine the RVF sero-prevalence in risk prone areas.

Gender disparities operate in opposite directions for hospitalizations and mortality among individuals receiving long-term ART in rural Uganda.

Objectives: We conducted an analysis to determine if differences in health-seeking behaviour can explain gender disparities in mortality among long-term survivors receiving antiretroviral therapy (ART) in rural Uganda.

Methods: From June 2012 to January 2014, we enrolled patients receiving a first-line ART regimen for at least 4 years without previous viral load (VL) testing in Jinja, Uganda. We measured HIV VL at study entry.

Strategies for retention of heterosexual men in HIV care in sub-Saharan Africa: A systematic review.

Expansion of Antiretroviral Therapy (ART) programs in sub-Saharan Africa (SSA) has increased the number of people accessing treatment. However, the number of males accessing and being retained along the human immunodeficiency virus (HIV) care cascade is significantly below the UNAIDS target. Male gender has been associated with poor retention in HIV care programs, and little is known about strategies that reduce attrition of men in ART programs.

Reproductive intentions and corresponding use of safer conception methods and contraception among Ugandan HIV clients in serodiscordant relationships.

Context: Among people living with HIV in Uganda, desires to have a child and unplanned pregnancies are both common, while utilization of safer conception methods (SCM) and modern contraceptives are low.

Methods: Three hundred eighty-nine HIV clients who reported considering childbearing with their uninfected partner enrolled in a safer conception counseling intervention trial in Uganda. Multiple regression analysis and baseline data were used to examine correlates of reproductive intentions and behaviors, including use of safer conception methods and contraception.

Effectiveness and cost-effectiveness of group support psychotherapy delivered by trained lay health workers for depression treatment among people with HIV in Uganda: a cluster-randomised trial.

Background: WHO recommends the use of psychological interventions as first-line treatment for depression in low-income and middle-income countries. However, evaluations of the effectiveness and cost-effectiveness of such interventions among people with HIV are scarce. Our aim was to establish the effectiveness of group support psychotherapy (GSP) delivered by lay health workers for depression treatment among people living with HIV in a rural area of Uganda on a large scale.

Peer distribution of HIV self-test kits to men who have sex with men to identify undiagnosed HIV infection in Uganda: A pilot study.

Introduction: One-in-three men who have sex with men (MSM) in Uganda have never tested for HIV. Peer-driven HIV testing strategies could increase testing coverage among non-testers. We evaluated the yield of peer distributed HIV self-test kits compared with standard-of-care testing approaches in identifying undiagnosed HIV infection.

Lack of effectiveness of adherence counselling in reversing virological failure among patients on long-term antiretroviral therapy in rural Uganda.

Objectives: The current World Health Organization and Uganda Ministry of Health HIV treatment guidelines recommend that asymptomatic patients who have a viral load (VL) ≥ 1000 HIV-1 RNA copies/mL should receive adherence counselling and repeat VL testing before switching to second-line therapy. We evaluated the effectiveness of this strategy in a large HIV treatment programme of The AIDS Support Organisation Jinja in Jinja, Uganda.

Methods: We measured the HIV VL at enrolment, and for participants with VL ≥ 1000 copies/mL we informed them of their result, offered enhanced adherence counselling and repeated the VL measurement after 3 months.

Acceptability, perceived reliability and challenges associated with distributing HIV self-test kits to young MSM in Uganda: a qualitative study.

Introduction: HIV self-testing is a flexible, accessible and acceptable emerging technology with a particular potential to identify people living with HIV who are reluctant to interact with conventional HIV testing approaches. We assessed the acceptability, perceived reliability and challenges associated with distributing HIV self-test (HIVST) to young men who have sex with men (MSM) in Uganda.

Methods: Between February and May, 2018, we enrolled 74 MSM aged ≥18 years purposively sampled and verbally consented to participate in six focus group discussions (FGDs) in The AIDS Support Organization (TASO Masaka and Entebbe).

Incidence rate of sexually transmitted infections among HIV infected patients on long-term ART in an urban and a rural clinic in Uganda.

Background: HIV immunosuppression increases susceptibility to other STIs and STIs can enhance HIV transmission, reduce CD4 cell count and increase viral load. Co-infections of HIV and STIs may thus reduce the preventive benefits of ART. Little is known about the incidence rate of STIs among long-term patients on ART.

Recruitment and Baseline Characteristics of Participants in the Social, Emotional, and Economic Empowerment Through Knowledge of Group Support Psychotherapy Study (SEEK-GSP): Cluster Randomized Controlled Trial.

Background: Psychosocial characteristics, including self-esteem, perceived social support, coping skills, stigma, discrimination, and poverty, are strongly correlated with depression symptoms. However, data on the extent of these correlations among persons living with HIV and the associations between psychosocial characteristics and HIV treatment outcomes are limited in sub-Saharan Africa.

Objective: This paper aims to describe the recruitment process and baseline characteristics associated with depression in a sample of HIV-positive people in a cluster randomized trial of group support psychotherapy (GSP) for depression delivered by trained lay health workers (LHWs).

A pilot trial of the peer-based distribution of HIV self-test kits among fishermen in Bulisa, Uganda.

Background: HIV self-testing (HIVST) addresses barriers to HIV diagnosis among men, but current approaches to distributing HIVST kits only reach a subset of the men requiring testing.

Methods: We conducted a pilot trial of the secondary distribution of HIVST kits through peer networks in fishing communities of Buliisa district (Uganda). We recruited distributors ("seeds") among male patients of a health facility, and among community members.

Risky sexual behavior among patients on long-term antiretroviral therapy: a prospective cohort study in urban and rural Uganda.

Background: While the effects of initiation of antiretroviral treatment (ART) on risky sexual behavior have been extensively studied, less is known about the long-term changes in risky sexual behavior over time in resource-poor settings.

Methods: We conducted a secondary longitudinal analysis of one rural and one urban cohort of patients who initiated ART in Uganda between April 2004 and July 2007 followed up-to 2016. Data on sexual behavior were collected every 6 months for 3.
