District Health Officer Perceptions of PEPFAR's Influence on the Health System in Uganda, 2005-2011.

BACKGROUND: Vertically oriented global health initiatives (GHIs) addressing the HIV/AIDS epidemic, including the President's Emergency Plan for AIDS Relief (PEPFAR), have successfully contributed to reducing HIV/AIDS related morbidity and mortality. However, there is still debate about whether these disease-specific programs have improved or harmed health systems overall, especially with respect to non-HIV health needs. METHODS: As part of a larger evaluation of PEPFAR's effects on the health system between 2005-2011, we collected qualitative and quantitative data through semi-structured interviews with District Health Officers (DHOs) from all 112 districts in Uganda. We asked DHOs to share their perceptions about the ways in which HIV programs (largely PEPFAR in the Ugandan context) had helped and harmed the health system. We then identified key themes among their responses using qualitative content analysis. RESULTS: Ugandan DHOs said PEPFAR had generally helped the health system by improving training, integrating HIV and non-HIV care, and directly providing resources. To a lesser extent, DHOs said PEPFAR caused the health system to focus too narrowly on HIV/AIDS, increased workload for already overburdened staff, and encouraged doctors to leave public sector jobs for higher-paid positions with HIV/AIDS programs. CONCLUSION: Health system leaders in Uganda at the district level were appreciative of resources aimed at HIV they could often apply for broader purposes. As HIV infection becomes a chronic disease requiring strong health systems to manage sustained patient care over time, Uganda's weak health systems will require broad infrastructure improvements inconsistent with narrow vertical health programming.

"The Cango Lyec Project - Healing the Elephant": HIV related vulnerabilities of post-conflict affected populations aged 13-49 years living in three Mid-Northern Uganda districts.

BACKGROUND: The protracted war between the Government of Uganda and the Lord's Resistance Army in Northern Uganda (1996-2006) resulted in widespread atrocities, destruction of health infrastructure and services, weakening the social and economic fabric of the affected populations, internal displacement and death. Despite grave concerns that increased spread of HIV/AIDS may be devastating to post conflict Northern Uganda, empirical epidemiological data describing the legacy of the war on HIV infection are scarce. METHODS: The 'Cango Lyec' Project is an open cohort study involving conflict-affected populations living in three districts of Gulu, Nwoya and Amuru in mid-northern Uganda. Between November 2011 and July 2012, 8 study communities randomly selected out of 32, were mapped and house-to-house census conducted to enumerate the entire community population. Consenting participants aged 13-49 years were enrolled and interviewer-administered data were collected on trauma, depression and socio-demographic-behavioural characteristics, in the local Luo language. Venous blood was taken for HIV and syphilis serology. Multivariable logistic regression was used to determine factors associated with HIV prevalence at baseline. RESULTS: A total of 2954 participants were eligible, of whom 2449 were enrolled. Among 2388 participants with known HIV status, HIV prevalence was 12.2% (95%CI: 10.8-13.8), higher in females (14.6%) than males (8.5%, p < 0.001), higher in Gulu (15.2%) than Nwoya (11.6%, p < 0.001) and Amuru (7.5%, p = 0.006) districts. In this post-conflict period, HIV infection was significantly associated with war trauma experiences (Adj. OR = 2.50; 95%CI: 1.31-4.79), the psychiatric problems of PTSD (Adj. OR = 1.44; 95%CI: 1.06-1.96), Major Depressive Disorder (Adj. OR = 1.89; 95%CI: 1.28-2.80) and suicidal ideation (Adj. OR = 1.87; 95%CI: 1.34-2.61). Other HIV related vulnerabilities included older age, being married, separated, divorced or widowed, residing in an urban district, ulcerative sexually transmitted infections, and staying in a female headed household. There was no evidence in this study to suggest that people with a history of abduction were more likely to be HIV positive. CONCLUSIONS: HIV prevalence in this post conflict-affected population is high and is significantly associated with age, trauma, depression, history of ulcerative STIs, and residing in more urban districts. Evidence-based HIV/STI prevention programs and culturally safe, gender and trauma-informed are urgently needed.

Did PEPFAR investments result in health system strengthening? A retrospective longitudinal study measuring non-HIV health service utilization at the district level.

OBJECTIVES : PEPFAR's initial rapid scale-up approach was largely a vertical effort focused fairly exclusively on AIDS. The purpose of our research was to identify spill-over health system effects, if any, of investments intended to stem the HIV epidemic over a 6-year period with evidence from Uganda. The test of whether there were health system expansions (aside from direct HIV programming) was evidence of increases in utilization of non-HIV services-such as outpatient visits, in-facility births or immunizations-that could be associated with varying levels of PEPFAR investments at the district level. METHODS : Uganda's Health Management Information System article-based records were available from mid-2005 onwards. We visited all 112 District Health offices to collect routine monthly reports (which contain data aggregated from monthly facility reports) and annual reports (which contain data aggregated from annual facility reports). Counts of individuals on anti-retroviral therapy (ART) at year-end served as our primary predictor variable. We grouped district-months into tertiles of high, medium or low PEPFAR investment based on their total reported number of patients on ART at the end of the year. We generated incidence-rate ratios, interpreted as the relative rate of the outcome measure in relation to the lowest investment PEPFAR tertile, holding constant control variables in the model. RESULTS : We found PEPFAR investment overall was associated with small declines in service volumes in several key areas of non-HIV care (outpatient care for young children, TB tests and in-facility deliveries), after adjusting for sanitation, elementary education and HIV prevalence. For example, districts with medium and high ART investment had 11% fewer outpatient visits for children aged 4 and younger compared with low investment districts, incidence rate ratio (IRR) of 0.89 for high investment compared with low (95% CI, 0.85-0.94) and IRR of 0.93 for medium compared with low (0.90-0.96). Similarly, 22% fewer TB sputum tests were performed in high investment districts compared with low investment, [IRR 0.78 (0.72-0.85)] and 13% fewer in medium compared with low, [IRR 0.88 (0.83-0.94)]. Districts with medium and high ART investment had 5% fewer in-facility deliveries compared with low investment districts [IRR 0.95 for high compared with low, (91-1.00) and 0.96 for medium compared with low (0.93-0.99)]. Although not statistically significant, the rate of maternal deaths in high investment district-months was 13% lower than observed in low investment districts. CONCLUSIONS : This study sought to understand whether PEPFAR, as a vertical programme, may have had a spill-over effect on the health system generally, as measured by utilization. Our conclusion is that it did not, at least not in Uganda.

An assessment of fishing communities around Lake Victoria, Uganda, as potential populations for future HIV vaccine efficacy studies: an observational cohort study.

BACKGROUND: An effective HIV vaccine is still elusive. Of the 9 HIV preventive vaccine efficacy trials conducted to-date, only one reported positive results of modest efficacy. More efficacy trials need to be conducted before one or more vaccines are eventually licensed. We assessed the suitability of fishing communities in Uganda for future HIV vaccine efficacy trials. METHODS: A community-based cohort study was conducted among a random sample of 2191 participants aged 18-49 years. Data were collected on socio-demographic characteristics, HIV risky behaviors, and willingness to participate in future HIV vaccine trials (WTP). Venous blood was collected for HIV serological testing. Retention/follow rates and HIV incidence rates per 100 person years at-risk (pyar) were estimated. Adjusted prevalence proportion ratios (PPRs) of retention and odds ratios (ORs) of lack of WTP were estimated using log-binomial and logistic regression models respectively. RESULTS: Overall retention rate was 76.9% (1685/2191), highest (89%) among participants who had spent 5+ years in the community and lowest (54.1%) among those with <1 year stay. Significant predictors of retention included tribe/ethnicity, baseline HIV negative status, and longer than 1 year stay in the community. Overall WTP was 89.1% (1953/2191). Lack of WTP was significantly higher among women than men [adj.OR = 1.51 (95% CI, 1.14- 2.00)] and among participants who had stayed in fishing communities for 10 or more years relative to those with less than one year [adj.OR = 1.78 (95% CI, 1.11 - 2.88)]. Overall HIV incidence rate per 100 pyar was 3.39 (95% CI; 2.55 - 4.49). Participants aged 25-29 years had highest incidence rates (4.61 - 7.67/100 pyar) and high retention rates between 78.5 and 83.1%. In a combined analysis of retention and incidence rates participants aged 30+ years had retention rates ~80% but low incidence rates (2.45 - 3.57 per 100 pyar) while those aged 25-29 years had the highest incidence rates (4.61 - 7.67/100 pyar) and retention rates 78.5 - 83.1%. CONCLUSIONS: There is high HIV incidence, retention and WTP among fishing communities around L. Victoria, Uganda which make these communities appropriate for future HIV prevention efficacy studies including vaccine trials.

Designing and usage of a low-cost penile model for male medical circumcision skills training in Rakai, Uganda.

OBJECTIVE: To describe the designing and usage of a locally made low-cost penile model used for male medical circumcision (MMC) skills training. MATERIAL AND METHODS: The Rakai MMC training team has experienced a number of challenges during conduct of MMC skills training, one of which was the lack of a model to use for MMC skills training. To address this challenge, the Rakai MMC skills training team has designed and developed a low-cost penile model for use in MMC skills training. RESULTS: The model has been successfully used to demonstrate external penile anatomy, to describe the biological mechanisms through which male circumcision (MC) prevents HIV acquisition, and for demonstration and practice of the MMC procedures. CONCLUSIONS: With an initial cost of only $10 and a recurrent cost of $5, this is a cost-efficient and useful penile model that provides a simulation of normal penile anatomy for use in MC training in resource-limited settings. It has also been used as a visual aid in preoperative education of patients before receiving male circumcision. The model can be improved and scaled up to develop cheaper commercial penile models.

Screening HIV-positive pregnant women for antiretroviral therapy: utility of self-reported symptoms.

In developing countries, Mother-to-Child Transmission-Plus programmes propose to identify lifelong antiretroviral therapy (ART)-eligible women during antenatal care. Identification using AIDS-related symptoms is the most feasible screening procedure in resource-limited settings. It is not known if symptomatology in pregnant women is correlated with clinical criteria for ART initiation based on CD(4)+ cell count or HIV-1 viral load. In this population of HIV-positive pregnant women from Rakai District, Uganda, 8-23% were eligible for treatment by CD(4)+ cell count criteria, and <1% met WHO staging criteria for AIDS. Using one or more symptoms to predict CD(4)+ cell count <350 cells/mm(3), sensitivity was 100%, specificity 11%, positive predictive value (PPV) 25%, and negative predictive value (NPV) 100%. When using one or more symptoms to predict viral load > or =100,000 cps/mL, sensitivity was 100%, specificity 10%, PPV 6%, and NPV 100%. Initiation of treatment based on self-reported symptoms will over-treat because the majority of pregnant women with symptoms would not be eligible for treatment under current guidelines, but asymptomatic pregnant women are unlikely to require ART.

Clinical illness as a marker for initiation of HIV antiretroviral therapy in a rural setting, Rakai, Uganda.

The aim of this study is to assess whether HIV-related illness and World Health Organization (WHO) clinical stage can be used to guide initiation of antiretroviral therapy (ART) in rural Rakai District, Uganda. A retrospective cohort analysis of 910 HIV-seroprevalent individuals randomly sampled from a community cohort was conducted. The associations between HIV-related clinical illness and HIV viral loads >55,000 copies/mL and death were evaluated as a guide for initiation of ART. Reporting one or more HIV-related illnesses was associated with high specificity for identifying HIV viral load >55,000 copies/mL and predicting death within 30 months. There were more deaths in those with one symptom at baseline (16.3%) and two or more symptoms (25.0%) than in those reporting no symptoms (9.6%; P = 0.001).HIV-related illness and WHO stage predicted disease progression. The specificity of clinical illness to predict viral load >55,000 copies/mL was high and could be used to rule in HIV disease requiring ART.
