Abstract: Background: Exclusive breastfeeding (EBF) is reported to be a life-saving intervention in low-income settings. The effect of breastfeeding counselling by peer counsellors was assessed in Africa. Methods:24 communities in Burkina Faso, 24 in Uganda, and 34 in South Africa were assigned in a 1:1 ratio, by use of a computer-generated randomisation sequence, to the control or intervention clusters. In the intervention group, we scheduled one antenatal breastfeeding peer counselling visit and four post-delivery visits by trained peers. The data gathering team were masked to the intervention allocation. The primary outcomes were prevalance of EBF and diarrhoea reported by mothers for infants aged 12 weeks and 24 weeks. Country-specific prevalence ratios were adjusted for cluster effects and sites. Analysis was by intention to treat. This study is registered with ClinicalTrials.gov, number NCT00397150. Findings 2579 mother–infant pairs were assigned to the intervention or control clusters in Burkina Faso (n=392 and n=402, respectively), Uganda (n=396 and n=369, respectively), and South Africa (n=535 and 485, respectively). The EBF prevalences based on 24-h recall at 12 weeks in the intervention and control clusters were 310 (79%) of 392 and 139 (35%) of 402, respectively, in Burkina Faso (prevalence ratio 2·29, 95% CI 1·33–3·92); 323 (82%) of 396 and 161 (44%) of 369, respectively, in Uganda (1·89, 1·70–2·11); and 56 (10%) of 535 and 30 (6%) of 485, respectively, in South Africa (1·72, 1·12–2·63). The EBF prevalences based on 7-day recall in the intervention and control clusters were 300 (77%) and 94 (23%), respectively, in Burkina Faso (3·27, 2·13–5·03); 305 (77%) and 125 (34%), respectively, in Uganda (2·30, 2·00–2·65); and 41 (8%) and 19 (4%), respectively, in South Africa (1·98, 1·30–3·02). At 24 weeks, the prevalences based on 24-h recall were 286 (73%) in the intervention cluster and 88 (22%) in the control cluster in Burkina Faso (3·33, 1·74–6·38); 232 (59%) and 57 (15%), respectively, in Uganda (3·83, 2·97–4·95); and 12 (2%) and two (<1%), respectively, in South Africa (5·70, 1·33–24·26). The prevalences based on 7-day recall were 279 (71%) in the intervention cluster and 38 (9%) in the control cluster in Burkina Faso (7·53, 4·42–12·82); 203 (51%) and 41 (11%), respectively, in Uganda (4·66, 3·35–6·49); and ten (2%) and one (<1%), respectively, in South Africa (9·83, 1·40–69·14). Diarrhoea prevalence at age 12 weeks in the intervention and control clusters was 20 (5%) and 36 (9%), respectively, in Burkina Faso (0·57, 0·27–1·22); 39 (10%) and 32 (9%), respectively, in Uganda (1·13, 0·81–1·59); and 45 (8%) and 33 (7%), respectively, in South Africa (1·16, 0·78–1·75). The prevalence at age 24 weeks in the intervention and control clusters was 26 (7%) and 32 (8%), respectively, in Burkina Faso (0·83, 0·45–1·54); 52 (13%) and 59 (16%), respectively, in Uganda (0·82, 0·58–1·15); and 54 (10%) and 33 (7%), respectively, in South Africa (1·31, 0·89–1·93). Interpretation: Low-intensity individual breastfeeding peer counselling is achievable and, although it does not affect the diarrhoea prevalence, can be used to effectively increase EBF prevalence in many sub-Saharan African settings.

Abstract: This case study with one lay adherence counsellor assessed the implementation of Options for Health, a sexual risk-reduction intervention based on Motivational Interviewing (MI), in an antiretroviral clinic in Cape Town, South Africa. In most cases Options was not delivered with fidelity and less than one-third of intended recipients received it; the counsellor often forgot to do Options, was unsure how to deal with particular cases and felt that there was not always time to do Options. Options was not implemented in a way that was consistent with MI. Revisions to the implementation plan and training programme are required. URI: http://hdl.handle.net/10566/473 Files in this item: 1

Abstract: OBJECTIVES. To assess the extent of inequalities in availability and utilisation of HIV services across South Africa. DESIGN. Cross-sectional descriptive study. Setting. Three districts reflecting different socio-economic conditions, but with similar levels of HIV infection, were purposively sampled. Outcome measures. Availability and utilisation of HIV services and management and support structures for programmes were assessed through the collection of secondary data supplemented by site visits. RESULTS. There were marked inequalities in service delivery between the three sites. Compared with two poorer sites, clinics at the urban site had greater availability of HIV services, including voluntary counselling and testing (100% v. 52% and 24% respectively), better uptake of this service (59 v. 9 and 5.5 clients per 1 000 adults respectively) and greater distribution of condoms (15.6 v. 8.2 condoms per adult male per year). Extra counsellors had also been employed at the urban site in contrast to the other 2 sites. The urban site also had far more intensive management support and monitoring, with 1 manager per 12 health facilities compared with 1 manager per more than 90 health facilities at the other 2 sites. CONCLUSION. The process of scaling up of HIV services seems to be accentuating inequalities. The urban site in this study was better able to utilise the extra resources. In contrast, the poorer sites have thus far been unable to scale up the response to HIV even with the availability of extra resources. Unless policy makers pay more attention to equity, efficacious interventions may prove to be of limited effectiveness. URI: http://hdl.handle.net/10566/172 Files in this item: 1

Abstract: OBJECTIVE. To improve the clinical management of severely malnourished children in rural hospitals in South Africa. STUDY DESIGN. A pre- and post-intervention descriptive study in three stages: assessment of the clinical management of severely malnourished children, planning and implementing an action plan to improve quality of care, and monitoring and evaluating targeted activities. A participatory approach was used to involve district and hospital nutrition teams in all stages of the research. SETTING. Two rural Wrst-referral level hospitals (Mary Theresa and Sipetu) in Mount Frere District, Eastern Cape Province. MAIN MEASURES. A retrospective record review of all admissions for severe malnutrition to obtain patient characteristics and case fatality rates, a detailed review of randomly selected cases to illustrate general case management, structured observations in the paediatric wards to assess adequacy of resources for care of malnourished children, and in-depth interviews and focus group discussions with nursing and medical staff to identify barriers to improved quality of care. RESULTS. Before the study, case fatality rates were 50% and 28% in Mary Theresa and Sipetu hospitals, respectively. Information from case studies, observations, interviews, and focus group discussions revealed many inadequacies in knowledge, resources, and practices. The hospital nutrition team developed and implemented an action plan to improve the quality of care and developed tools for monitoring its implementation and evaluating its impact. In the 12-month period immediately after implementation, case fatality rates fell by ∼25% in both hospitals. CONCLUSION. Participatory research led to the formation of a hospital nutrition team, which identiWed shortcomings in the clinical management of severely malnourished children and took action to improve quality of care. These actions were associated with a reduction in case fatality rates. URI: http://hdl.handle.net/10566/294 Files in this item: 1

Abstract: Background: The objective of this study was to examine missed opportunities for participation in a prevention of mother-to-child transmission (PMTCT) programme in three sites in South Africa. A rapid anthropological assessment was used to collect in-depth data from 58 HIV-positive women who were enrolled in a larger cohort study to assess mother-to-child HIV transmission. Semistructured interviews were conducted with the women in order to gain an understanding of their experiences of antenatal care and to identify missed opportunities for participation in PMTCT. Results: 15 women actually missed their nevirapine not because of stigma and ignorance but because of health systems failures. Six were not tested for HIV during antenatal care. Two were tested but did not receive their results. Seven were tested and received their results, but did not receive nevirapine. Health Systems failure for these programme leakages ranged from nonavailability of counselors, supplies such as HIV test kits, consent forms, health staff giving the women incorrect instructions about when to take the tablet and health staff not supplying the women with the tablet to take. Conclusion: HIV testing enables access to PMTCT interventions and should therefore be strengthened. The single dose nevirapine regimen is simple to implement but the all or nothing nature of the regimen may result in many missed opportunities. A short course dual or triple drug regimen could increase the effectiveness of PMTCT programmes. URI: http://hdl.handle.net/10566/429 Files in this item: 1

Abstract: Interviews conducted in South Africa found that awareness of antiretroviral therapy was generally poor. Antiretroviral drugs were not perceived as new, but one of many alternative therapies for HIV/AIDS. Respondents had more detailed knowledge of indications, effects and how to access alternative treatments, which is bolstered by the active promotion and legitimization of alternative treatments. Many expressed a lack of excitement about the introduction of antiretroviral therapy, and little change in their attitudes concerning the epidemic.

Abstract: BACKGROUND: In South Africa the need to integrate HIV, TB and STI programmes has been recognised at a policy and organisation level; the challenge is now one of translating policies into relevant actions and monitoring implementation to ensure that the anticipated benefits of integration are achieved. In this research, set in public primary care services in Cape Town, South Africa, we set out to determine how middle level managers could be empowered to monitor the implementation of an effective, integrated HIV/TB/STI service. METHODS: A team of managers and researchers designed an evaluation tool to measure implementation of key components of an integrated HIV/TB/STI package with a focus on integration. They used a comprehensive health systems framework based on conditions for programme effectiveness and then identified and collected tracer indicators. The tool was extensively piloted in two rounds involving 49 clinics in 2003 and 2004 to identify data necessary for effective facility-level management. A subsequent evaluation of 16 clinics (2 per health sub district, 12% of all public primary care facilities) was done in February 2006. RESULTS: 16 clinics were reviewed and 635 records sampled. Client access to HIV/TB/STI programmes was limited in that 50% of facilities routinely deferred clients. Whilst the physical infrastructure and staff were available, there was problem with capacity in that there was insufficient staff training (for example, only 40% of clinical staff trained in HIV care). Weaknesses were identified in quality of care (for example, only 57% of HIV clients were staged in accordance with protocols) and continuity of care (for example, only 24% of VCT clients diagnosed with HIV were followed up for medical assessment). Facility and programme managers felt that the evaluation tool generated information that was useful to manage the programmes at facility and district level. On the basis of the results facility managers drew up action plans to address three areas of weakness within their own facility. CONCLUSIONS: This use of the tool which is designed to empower programme and facility managers demonstrates how engaging middle managers is crucial in translating policies into relevant actions.

Abstract: This paper describes key findings of a household livelihood survey conducted in impoverished African settlements in Cape Town, one of Africa’s wealthiest cities. Poverty in these areas is strongly shaped by the history of the Eastern Cape’s adverse spatial incorporation into the South African economy. Migrants from the rural areas are highly dependent on and integrated into the increasingly monetized economy – but are simultaneously marginalized and adversely incorporated within it. Survey findings show the costs and implications of this failure of the formal economy to provide adequate livelihoods. While many eke out a living in a vital yet marginal informal economy, these strategies are thoroughly linked to and dependent on the income that can be secured through participation in the formal job market. Those who are unable to find a foothold in the urban economy are highly vulnerable and are at risk of being confined to long-term poverty traps.
