Tuberculosis (TB) is the leading cause of death among people living with human immunodeficiency virus (PLHIV), and sub-Saharan Africa has a particularly heavy burden of HIV-associated TB. Although effective TB preventive treatment (TPT) has been available for decades and shorter regimens are newly available in some settings, TPT coverage among PLHIV is suboptimal, leading to preventable illness and death. In 2018, the United Nations High-Level Meeting on Ending Tuberculosis called for ambitious new targets for TPT coverage among PLHIV and many countries in sub-Saharan Africa have redoubled their efforts to take TPT to scale. Importantly, however, this push to expand TPT among PLHIV is taking place in the context of a changing HIV treatment delivery landscape. Countries in sub-Saharan Africa are at the forefront of innovative changes in HIV program design, including a shift towards less-intensive differentiated service delivery (DSD) models for stable patients doing well on antiretroviral therapy. Understanding the opportunities and challenges that DSD presents for TB diagnosis, prevention and linkage to care among PLHIV will be critical to success.

IntroductionThe World Health Organization now recommends dolutegravir (DTG) as part of the preferred first-line treatment for all adults living with HIV including women who may become pregnant. The new regimen with its high barrier to resistance, shortened time to suppression, superior side effects profile, and lower health sector and individual costs, represents a significant improvement. The recommendation removes an important obstacle to accessing dolutegravir as an essential element in controlling the epidemic. DiscussionTranslating science to policy to HIV service delivery is complex and vulnerable to significant delays. WHO, assuming a regulatory role, used preliminary Botswana Tsepamo study information regarding neural tube defects to issue a “safety signal” regarding DTG in May 2018. Regulatory evaluations of rare adverse reactions are complex, take time, and require considerable subject area specific expertise. After over a year, the WHO reversed its initial findings and issued revised treatment recommendations. However, the mixed messaging and confusion around dolutegravir’s safety profile has delayed national level adoption. The pace of national adoption of new WHO recommendations is measurable through published national guidelines and/or circulars available in the public domain. After 2015, published guidelines for 22 of 46 sub-Saharan countries (94% of 2018 regional HIV burden) showed that only three countries representing 4% of regional burden have adopted the new WHO preferred 1st line recommendations. ConclusionsMonitoring and evaluating the translation of science to service delivery is a critical element of successful disease control and elimination. The DTG false alarm and ongoing delayed access provides an opportunity to learn valuable lessons and implement corrective actions. However, lessons can only be learned by accurately describing and examining the timeline, processes, and impact of policy decisions that can adversely impact millions of people living with HIV. As with any successful global disease elimination effort or major project, it is important to establish a critical pathway for translation of science to service delivery and hold people and agencies accountable for their roles in accelerating and/or delaying progress.

Summary Many countries in sub-Saharan Africa have made antiretroviral therapy (ART) available in urban settings, but the progress of treatment expansion into rural Africa has been slower. We analysed routine data for patients enrolled in a rural HIV treatment programme in Zambézia Province, Mozambique (1 June 2006 through 30 March 2009). There were 12,218 patients who were ≥15 years old enrolled (69% women). Median age was 25 years for women and 31 years for men. Older age and higher level of education were strongly predictive of ART initiation (P < 0.001). Patients with a CD4+ count of 350 cells/μL versus 50 cells/μL were less likely to begin ART (odds ratio [OR]: 0.19, 95% confidence interval [CI]: 0.16-0.23). In rural sub-Saharan Africa, HIV testing, linkage to care, logistics for ART initiation and fears among some patients to take ART require specialized planning to maximize successes. Sustainability will require improved health manpower, infrastructure, stable funding, continuous drug supplies, patient record systems and, most importantly, community engagement.

Introduction: Differentiated service delivery (DSD) models for antiretroviral treatment (ART) for HIV are being scaled up in the expectation that they will improve the quality and efficiency of treatment delivery and reduce costs while maintaining at least equivalent clinical outcomes. Even this minimum requirement of equivalent clinical outcomes is poorly documented for most models and settings, however. We reviewed the recent literature on DSD models to describe what is known about clinical outcomes. Methods: We conducted a rapid systematic review of peer-reviewed publications in PubMed, Embase, and the Web of Science and major international conference abstracts that reported outcomes of DSD models for the provision of ART in sub-Saharan Africa from January 1, 2016 to September 12, 2019. Sources reporting standard clinical HIV treatment metrics, primarily retention in care and viral load suppression, were reviewed and categorized by DSD model and source quality assessed. Results and Discussion: Twenty-nine papers and abstracts describing 37 DSD models and reporting 52 discrete outcomes met search inclusion criteria. Of the 37 models, 7 (19%) were facility-based individual models, 12 (32%) out-of-facility based individual models, 5 (14%) client-led groups, and 13 (35%) healthcare worker-led groups. Retention was reported for 73% of the models and viral suppression for 57%. Where a comparison with conventional care was provided, retention in most DSD models was within 5% of that for conventional care; where no comparison was provided, retention generally exceeded 80%. For viral suppression, all those with a comparison to conventional care reported a small increase in suppression in the DSD model; reported suppression exceeded 90% in 11/21 models. Analysis was limited by the extensive heterogeneity of study designs, outcomes, models, and populations. Most sources did not provide comparisons with conventional care, and metrics for assessing outcomes varied widely and were in many cases poorly defined. Conclusion: Existing evidence on the clinical outcomes of DSD models for HIV treatment in sub-Saharan Africa is limited in both quantity and quality but suggests that retention in care and viral suppression are roughly equivalent to those in conventional models of care.

Introduction: “Differentiated service delivery” (DSD) for antiretroviral therapy (ART) for HIV is rapidly being scaled up throughout sub-Saharan Africa, but only recently have data become available on the costs of DSD models to providers and patients. We synthesized recent studies of DSD model costs in five African countries. Methods: The studies included cluster randomized trials in Lesotho, Malawi, Zambia, and Zimbabwe and observational studies in Uganda and Zambia. For 3-5 models per country, studies collected patient-level data on clinical outcomes and provider costs for 12 months, and some studies surveyed patients about costs they incurred. We compared costs of differentiated models to those of conventional care and identified drivers of cost differences. We also report patient costs of seeking care. Results: The studies described 22 models, including facility-based conventional care. Of these, 13 were facility-based and 9 community-based models; 15 were individual and 7 group models. Average provider cost/patient/year ranged from $100 in Zambia to $187 in Zimbabwe, in both cases for facility-based conventional care. Conventional care was less expensive than any other model in the Zambia observational study, more expensive than any other model in Lesotho, Malawi, and Zimbabwe, and in the middle of the range in the Zambia trial and the observational study in Uganda. Models incorporating 6-month dispensing were consistently less expensive to the provider per patient treated. Savings to patients were substantial for most models, with patients’ costs roughly halved. Conclusion: In five field studies of the costs of DSD models for HIV treatment, most models within each country had relatively similar costs, except for 6-month dispensing models, which were slightly less expensive. Most models provided substantial savings to patients. Research is needed to understand the effect of DSD models on the costs of ART programmes as a whole.

AbstractLack of access to modern forms of energy hampers efforts to reduce poverty. The provision of electricity to off-grid communities is therefore a long-standing developmental goal. Yet, many off-grid electrification projects neglect mid- and long-term operation and maintenance costs. When this is the case, electricity services are unlikely to be affordable to the communities that are the project’s primary target. Here we show that, compared with diesel-powered electricity generation systems, solar photovoltaic systems are more affordable to no less than 36% of the unelectrified populations in East Asia, South Asia, and sub-Saharan Africa. We do so by developing geo-referenced estimates of affordability at a high level of resolution (1 km2). The analysis illustrates the differences in affordability that may be found at the subnational level, which underscores that electrification investments should be informed by subnational data.

AbstractThis note discusses the challenges of water service delivery before, during and after protracted armed conflict, focusing on barriers that may impede successful transition from emergency to development interventions. The barriers are grouped according to three major contributing factors (three “C”s): culture (organizational goals and procedures), cash (financing practices) and capacity (know-how). By way of examples, the note explores ways in which development agencies can overcome these barriers during the three phases of a protracted armed conflict, using examples of World Bank projects and experiences in the Middle East and Sub-Saharan Africa. Before the crisis, development agencies need to work to prevent armed conflict. In a situation of active armed conflict or when conflict escalates, development agencies need to remain engaged as much as possible, as this will speed up post-conflict recovery. When conflict subsides, development agencies need to balance the relative effort placed on providing urgently needed emergency relief and water supply and sanitation services with the effort placed on re-establishing sector oversight roles and capacity of local institutions to oversee and manage service delivery in the long term.
