Changing HIV treatment eligibility under health system constraints in sub-Saharan Africa: investment needs, population health gains, and cost-effectiveness.

ABSTRACT:

Objective

We estimated the investment needs, population health gains, and cost-effectiveness of different policy options for scaling-up prevention and treatment of HIV in the 10 countries that currently comprise 80% of all people living with HIV in sub-Saharan Africa (Ethiopia, Kenya, Malawi, Mozambique, Nigeria, South Africa, Tanzania, Uganda, Zambia, and Zimbabwe).

Design

We adapted the established STDSIM model to capture the health system dynamics: demand-side and supply-side constraints in the delivery of antiretroviral treatment (ART).

Methods

We compared different scenarios of supply-side (i.e. health system capacity) and demand-side (i.e. health seeking behavior) constraints, and determined the impact of changing guidelines to ART eligibility at any CD4 cell count within these constraints.

Results

Continuing current scale-up would require US$178 billion by 2050. Changing guidelines to ART at any CD4 cell count is cost-effective under all constraints tested in the model, especially in demand-side constrained health systems because earlier initiation prevents loss-to-follow-up of patients not yet eligible. Changing guidelines under current demand-side constraints would avert 1.8 million infections at US$208 per life-year saved.

Conclusion

Treatment eligibility at any CD4 cell count would be cost-effective, even under health system constraints. Excessive loss-to-follow-up and mortality in patients not eligible for treatment can be avoided by changing guidelines in demand-side constrained systems. The financial obligation for sustaining the AIDS response in sub-Saharan Africa over the next 35 years is substantial and requires strong, long-term commitment of policy-makers and donors to continue to allocate substantial parts of their budgets.

Project description:BackgroundSex and gender have been shown to influence health literacy, health seeking behaviour, and health outcomes. However, research examining the links between gender and health has mainly focused on women's health, which is a long-standing global health priority. We examine literature focused on the 'missing men' in global health research, in particular empirical studies that document interventions, programmes, and services targeting men's health issues in Sub-Saharan Africa. Within these studies, we identify dominant conceptualisations of men and men's health and how these have influenced the design of men's health interventions and services.MethodsThis is a scoping review of published and grey literature. Following comprehensive searches, we included 56 studies in the review. We conducted a bibliographic analysis of all studies and used inductive methods to analyse textual excerpts referring to conceptualizations of men and service design. An existing framework to categorise services, interventions, or programs according to their gender-responsiveness was adapted and used for the latter analysis.ResultsFrom the included studies, we distinguished four principal ways in which men were conceptualized in programs and interventions: men are variously depicted as 'gatekeepers'; 'masculine' men, 'marginal' men and as 'clients. Additionally, we classified the gender-responsiveness of interventions, services or programmes described in the studies within the following categories: gender-neutral, -partnering, -sensitive and -transformative. Interventions described are predominantly gender-neutral or gender-partnering, with limited data available on transformative interventions. Health systems design features - focused mainly on achieving women's access to, and uptake of services - may contribute to the latter gap leading to poor access and engagement of men with health services.ConclusionThis review highlights the need for transformation in sub-Saharan African health systems towards greater consideration of men's health issues and health-seeking patterns.

Project description:BackgroundSub Saharan African (SSA) prisons have seen a substantial increase in women prisoners in recent years. Despite this increase, women prisoners constitute a minority in male dominated prison environments, and their special health needs are often neglected. Research activity on prison health remains scant in SSA, with gathering of strategic information generally restricted to infectious diseases (human immunodeficiency virus infection HIV/tuberculosis TB), and particularly focused on male prisoners. Health care provisions for women (and pregnant women) in SSA prisons are anecdotally reported to fall far short of the equivalence care standards mandated by human rights and international recommendations, and the recent agreements set out in the Southern African Development Community (SADC) Minimum Standards for HIV in Prisons.MethodsA scoping review mapped what is currently known about women prisoners' health experiences, unique prison health care needs and health care outcomes in SSA. A systematic search collected and reviewed all available and relevant published and grey literature (2000-2017). Following removal of duplicates and application of exclusion measures, 46 records remained, which represented 18 of the 49 SSA countries. These records were subsequently charted and thematically analysed.ResultsThree themes were generated; 'The Prison Regime'; 'Navigating inside the Prison Health Infrastructure' and 'Accessing the outside Community and Primary Care Health Services'. Women in SSA prisons experience the same substandard nutrition, overcrowding and unhygienic conditions which exacerbate poor health and infectious disease transmission as males. Human rights abuses, substandard prison conditions and poor access to prison based and community clinical care, along with the invisible nature of women and that of their unique health needs are deplorable.ConclusionsThe review has highlighted the dearth of gender specific strategic information on women prisoners in the region, appalling environmental conditions and prison health care provision, and violation of human rights for those incarcerated. Enhanced donor support, resource allocation, prison health and population health policy reform, health systems surveillance and gender sensitive prison health service provision is warranted. This will help address women prisoners' conditions and their specific health needs in SSA prisons, and ultimately bridge the gap between prison and population health in the region.

Project description:Sub-Saharan Africa represents 69% of the total number of individuals living with HIV infection worldwide and 72% of AIDS deaths globally. Pulmonary infection is a common and frequently fatal complication, though little is known regarding the lower airway microbiome composition of this population. Our objectives were to characterize the lower airway microbiome of Ugandan HIV-infected patients with pneumonia, to determine relationships with demographic, clinical, immunological, and microbiological variables and to compare the composition and predicted metagenome of these communities to a comparable cohort of patients in the US (San Francisco). Bronchoalveolar lavage samples from a cohort of 60 Ugandan HIV-infected patients with acute pneumonia were collected. Amplified 16S ribosomal RNA was profiled and aforementioned relationships examined. Ugandan airway microbiome composition and predicted metagenomic function were compared to US HIV-infected pneumonia patients. Among the most common bacterial pulmonary pathogens, Pseudomonas aeruginosa was most prevalent in the Ugandan cohort. Patients with a richer and more diverse airway microbiome exhibited lower bacterial burden, enrichment of members of the Lachnospiraceae and sulfur-reducing bacteria and reduced expression of TNF-alpha and matrix metalloproteinase-9. Compared to San Franciscan patients, Ugandan airway microbiome were significantly richer, and compositionally distinct with predicted metagenomes that encoded a multitude of distinct pathogenic pathways e.g secretion systems. Ugandan pneumonia-associated airway microbiome is compositionally and functionally distinct from those detected in comparable patients in developed countries, a feature which may contribute to adverse outcomes in this population. Please note that the data from the comparable cohort of patients in the USUS data was published as supplemental material of PMID: 22760045 but not submitted to GEO The 'patient_info.txt' contains 12 clinical, 7 immunological and 3 microbiological variables for each patient.

Project description:BACKGROUND: Around 8.8 million children under-five die each year, mostly due to infectious diseases, including malaria that accounts for 16% of deaths in Africa, but the impact of international financing of malaria control on under-five mortality in sub-Saharan Africa has not been examined. METHODS AND FINDINGS: We combined multiple data sources and used panel data regression analysis to study the relationship among investment, service delivery/intervention coverage, and impact on child health by observing changes in 34 sub-Saharan African countries over 2002-2008. We used Lives Saved Tool to estimate the number of lives saved from coverage increase of insecticide-treated nets (ITNs)/indoor residual spraying (IRS). As an indicator of outcome, we also used under-five mortality rate. Global Fund investments comprised more than 70% of the Official Development Assistance (ODA) for malaria control in 34 countries. Each $1 million ODA for malaria enabled distribution of 50,478 ITNs [95%CI: 37,774-63,182] in the disbursement year. 1,000 additional ITNs distributed saved 0.625 lives [95%CI: 0.369-0.881]. Cumulatively Global Fund investments that increased ITN/IRS coverage in 2002-2008 prevented an estimated 240,000 deaths. Countries with higher malaria burden received less ODA disbursement per person-at-risk compared to lower-burden countries ($3.90 vs. $7.05). Increased ITN/IRS coverage in high-burden countries led to 3,575 lives saved per 1 million children, as compared with 914 lives in lower-burden countries. Impact of ITN/IRS coverage on under-five mortality was significant among major child health interventions such as immunisation showing that 10% increase in households with ITN/IRS would reduce 1.5 [95%CI: 0.3-2.8] child deaths per 1000 live births. CONCLUSIONS: Along with other key child survival interventions, increased ITNs/IRS coverage has significantly contributed to child mortality reduction since 2002. ITN/IRS scale-up can be more efficiently prioritized to countries where malaria is a major cause of child deaths to save greater number of lives with available resources.
