HIV Prevention 2020: a framework for delivery and a call for action.

Although effective programmes are available and several countries have seen substantial declines in new HIV infections, progress in the reduction of adult HIV incidence has been slower than expected worldwide and many countries have not had large decreases in new infections in adults despite large reductions in paediatric infections. Reasons for slow progress include inadequate commitment, investment, focus, scale, and quality of implementation of prevention and treatment interventions. The UNAIDS-Lancet Commission on Defeating AIDS-Advancing Global Health reported that the provision of large-scale, effective HIV prevention programmes has failed and called on stakeholders to "get serious about HIV prevention". An ambitious worldwide target has been set by UNAIDS to reduce new infections below 500 000 by 2020-a 75% reduction from 2010. Models show that such a reduction requires a combination of primary prevention interventions and preventative effects of treatment. Achievement of the target will require more effective delivery of HIV prevention for sufficient coverage in populations at greatest risk of infection ensuring that interventions that have proved effective are made available, barriers to their uptake are overcome, demand is created, and use is consistent and occurs at the right scale with high coverage. This paper discusses how programmatic targets for prevention in a worldwide plan could be used to re-energise the HIV prevention approach. A management framework is proposed outlining global, regional, national, and subnational actions and is summarised in a call for action on HIV prevention for 2020.

Is there scope for cost savings and efficiency gains in HIV services? A systematic review of the evidence from low- and middle-income countries.

OBJECTIVE: To synthesize the data available--on costs, efficiency and economies of scale and scope--for the six basic programmes of the UNAIDS Strategic Investment Framework, to inform those planning the scale-up of human immunodeficiency virus (HIV) services in low- and middle-income countries. METHODS: The relevant peer-reviewed and "grey" literature from low- and middle-income countries was systematically reviewed. Search and analysis followed Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. FINDINGS: Of the 82 empirical costing and efficiency studies identified, nine provided data on economies of scale. Scale explained much of the variation in the costs of several HIV services, particularly those of targeted HIV prevention for key populations and HIV testing and treatment. There is some evidence of economies of scope from integrating HIV counselling and testing services with several other services. Cost efficiency may also be improved by reducing input prices, task shifting and improving client adherence. CONCLUSION: HIV programmes need to optimize the scale of service provision to achieve efficiency. Interventions that may enhance the potential for economies of scale include intensifying demand-creation activities, reducing the costs for service users, expanding existing programmes rather than creating new structures, and reducing attrition of existing service users. Models for integrated service delivery--which is, potentially, more efficient than the implementation of stand-alone services--should be investigated further. Further experimental evidence is required to understand how to best achieve efficiency gains in HIV programmes and assess the cost-effectiveness of each service-delivery model.

Knowledge of, attitudes towards, and practices relating to child-spacing methods in northern Burkina Faso.

This study was carried out to document current trends in knowledge of, attitudes towards, and practices relating to traditional and modern child-spacing methods in a remote area in northern Burkina Faso. Information on sexual abstention, weaning, and contraception was elicited from 296 women of reproductive age, involving 413 postpartum intervals. A number of older women and key informants were also interviewed. The findings depicted significant diversity in that durations of individual postpartum sexual abstinence varied between 40 days and 3 years, with shorter durations associated with stricter adherence to Islamic beliefs and, possibly, a trend towards a less collective and, for the family unit, more labour intensive, agro-pastoral subsistence economy. Although durations of amenorrhoea were relatively short at between (median) 9 and 11 months, they determined the length of non-susceptible periods in almost 90% of cases. The median timing of weaning was stable at 24 months across all three main ethnic groups. However, changes in the frequency and type of complementary feeds may have impacted on the duration of amenorrhoea. Both demand for modem contraception and contraceptive prevalence (< 1%) were very low. The creation of new child-spacing norms and the promotion of modern contraceptive methods are likely to be successful in areas like this one only, if the population can be sensitized to the idea that Islam does not necessarily discourage contraception.
