    South African child deaths 1990-2011: have HIV services reversed the trend enough to meet Millennium Development Goal 4?
    (Lippincott Williams & Wilkins, 2013) Kerber, Kate J.; Lawn, Joy E.; Sanders, David; Jackson, Debra; Johnson, Leigh F.; Maye, Mary; Dorrington, Rob E.; Phillips, Heston; Bradshaw, Debbie; Nannan, Nadine; Msemburi, William; Oestergaard, Mikkel Z.; Walker, Neff P.
    OBJECTIVE: To analyse trends in under-five mortality rate in South Africa (1990–2011), particularly the contribution of AIDS deaths. METHODS: Three nationally used models for estimating AIDS deaths in children were systematically reviewed. The model outputs were compared with under-five mortality rate estimates for South Africa from two global estimation models. All estimates were compared with available empirical data. RESULTS: Differences between the models resulted in varying point estimates for underfive mortality but the trends were similar, with mortality increasing to a peak around 2005. The three models showing the contribution of AIDS suggest a maximum of 37– 39% of child deaths were due to AIDS in 2004–2005 which has since declined. Although the rate of progress from 1990 is not the 4.4% needed to meet Millennium Development Goal 4 for child survival, South Africa’s average annual rate of under-five mortality decline between 2006 and 2011 was between 6.3 and 10.2%. CONCLUSION: In 2005, South Africa was one of only four countries globally with an under-five mortality rate higher than the 1990 Millennium Development Goal baseline. Over the past 5 years, the country has achieved a rate of child mortality reduction exceeded by only three other countries. This rapid turnaround is likely due to scale-up of prevention of mother-to-child transmission of HIV, and to a lesser degree, the expanded roll-out of antiretroviral therapy. Emphasis on these programmes must continue, but failure to address other aspects of care including integrated high-quality maternal and neonatal care means that the decline in child mortality could stall.

    South-Africa (Goodstart III) trial: community based maternal and newborn care economic analysis
    (Oxford University Press, 2017) Daviaud, Emmanuelle; Nkonki, Lungiswa; Ijumba, Petrida; Doherty, Tanya; Lawn, Joy E.; Owen, Helen; Jackson, Debra; Tomlinson, Mark
    In light of South Africa’s generalized HIV/AIDS epidemic coupled with high infant mortality, we undertook a cluster Randomized Control Trial (2008–10) assessing the effect of Community Health Worker (CHW) antenatal and postnatal home visits on, amongst other indicators, levels of HIV-free survival, and exclusive and appropriate infant feeding at 12 weeks. Cost and time implications were calculated, by assessing the 15 participating CHWs, using financial records, mHealth and interviews. Sustainability and scalability were assessed, enabling identification of health system issues. The majority (96%) of women in the community received an average of 4.1 visits (target seven). The paid, single purpose CHWs spent 13 h/week on the programme. The financial cost per mother amounted to $94 ($23 per home visit). Modelling target coverage (95% mothers, seven visits) and increased efficiency showed that if CHWs spent 25 h/week on the programme, the number of CHWs required would decrease from 15 to 12. The intervention almost doubled exclusive breastfeeding (EBF) at 12 weeks and showed a 6% relative increase in EBF with each additional CHW visit. Home visit programmes improve access and prevention but are not an inexpensive alternative: the observed cost per home visit is twice that of a clinic visit and in target/efficiency scenario decreases to 70% of the cost of a clinic visit. Ensuring sustainability requires optimizing the design of programmes and deployment of human resources, whilst maintaining impact. However, low remuneration of CHWs leads to shorter working hours, low motivation and sub-optimal coverage even in a situation with well-resourced supervision. The community-based care programme in South-Africa is based on multi-purpose CHWs, its cost and impact should be compared with results from this study. Quality of support for multi-purpose CHWs may be the biggest challenge to address to achieving higher efficiency of community-based services.
