RESUMO
BACKGROUND: Despite free healthcare to pregnant women and children under the age of six, access to healthcare has failed to secure better child health outcomes amongst all children of the country. There is growing evidence of socioeconomic gradient on child health outcomes METHODS: The objectives of this study were to measure inequalities in child mortality, HIV transmission and vaccination coverage within a cohort of infants in South Africa. We also used the decomposition technique to identify the factors that contribute to the inequalities in these three child health outcomes. We used data from a prospective cohort study of mother-child pairs in three sites in South African. A relative index of household socio-economic status was developed using principal component analysis. This paper uses the concentration index to summarise inequalities in child mortality, HIV transmission and vaccination coverage. RESULTS: We observed disparities in the availability of infrastructure between least poor and most poor families, and inequalities in all measured child health outcomes. Overall, 75 (8.5%) infants died between birth and 36 weeks. Infant mortality and HIV transmission was higher among the poorest families within the sample. Immunisation coverage was higher among the least poor. The inequalities were mainly due to the area of residence and socio-economic position. CONCLUSION: This study provides evidence that socio-economic inequalities are highly prevalent within the relatively poor black population. Poor socio-economic position exposes infants to ill health. In addition, the use of immunisation services was lower in the poor households. These inequalities need to be explicitly addressed in future programme planning to improve child health for all South Africans.
RESUMO
OBJECTIVE: Previous studies on the operational effectiveness of programmes to reduce transmission of HIV from mother-to-child (PMTCT) in Africa have generally been hospital-based pilot studies with short follow-up periods. METHOD: Prospective cohort study to evaluate the routine operational effectiveness of the South African National PMTCT Programme, primarily measured by HIV-free survival at 36 weeks post-delivery. Three of eighteen pilot sites participating in the programme were selected as they reflected differences in circumstances, such as HIV prevalence, socioeconomic status and rural-urban location. A total of 665 HIV-positive mothers and their infants were followed. RESULTS: HIV-free survival at 36 weeks varied significantly across sites with 84% in Paarl, 74% in Umlazi and 65% in Rietvlei (P = 0.0003). Maternal viral load was the single most important factor associated with HIV transmission or death [hazard ratio (HR), 1.54; 95% confidence interval (CI), 1.21-1.95]. Adjusting for health system variables (fewer than four antenatal visits and no antenatal syphilis test) explained the difference between Rietvlei and Paarl (crude HR, 2.27; 95% CI, 1.36-3.77; adjusted HR, 1.81; 95% CI, 0.93-3.50). Exposure to breastmilk feeding explained the difference between Umlazi and Paarl (crude HR, 1.74; 95% CI, 1.06-2.84; adjusted HR, 1.41; 95% CI, 0.81-2.48). CONCLUSION: Ever breastfeeding and underlying inequities in healthcare quality within South Africa are predictors of PMTCT programme performance and will need to be addressed to optimize PMTCT effectiveness.

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. Semi-structured 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 non-availability 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.
RESUMO
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.

The use of community health workers (CHWs) has been advocated in both developed and developing countries for many years. This article reports the findings of a descriptive research study that explored the relationship between CHWs and nurses working in resource-poor settings in South Africa. The findings of the study highlight dimensions of complex interactions occurring between these two main providers of care at the district level. Understanding the primary interaction of CHWs with nurses offers further understanding of the broader role of CHWs within the district health system. It is evident that CHWs are ideally suited to play a pivotal role in supporting the public health services. However, their role and functions are not formalized and the effectiveness of programs is often not rigorously evaluated. This article discusses some of the issues related to this cadre of health worker and their role in public health care structures.

BACKGROUND: It is three years since the government of South Africa began implementing a PMTCT programme. Over this period of time attempts have been made to scale up this programme across all provinces under routine health service conditions. OBJECTIVES: To report on the uptake and performance of South Africa's national pilot programme for preventing mother to child HIV transmission (PMTCT) and to identify health system constraints to optimal coverage. METHODS: Routine programme data were collected from antenatal records and delivery registers at the pilot sites and interviews were conducted with health workers on site and with provincial programme managers. RESULTS: Routine PMTCT programme data were collected from all 18 pilot sites for the period January to December 2002. During this period, of 84406 women attending the sites for first antenatal visits, 47267 (56%) agreed to an HIV test. 14340 (30%) of the women tested were HIV positive and of these 7853 (55%) were dispensed nevirapine. 7950 (99%) of infants born to women identified as being HIV positive received nevirapine syrup. 58% (4196/7237) of HIV positive women expressed an intention to exclusively formula feed, and 42% (3041/7237) intended to exclusively breastfeed. 1907 infants were due for 12 month HIV testing between January and December 2002, of these 949 (50%) infants were tested. CONCLUSION: Programme effectiveness was limited by the low rate of HIV test acceptance, poor delivery of nevirapine to mothers and inability to track mother-infant pairs postnatally for 12-month HIV testing of infants. Infant feeding intentions of mothers suggest inadequate counselling and possible negative effects of the provision of free formula milk. The poor performance of the main components of this programme will seriously reduce its operational effectiveness. There is a need for greater integration of VCT within antenatal care, a review of the current policy of providing free formula milk and an alternative model for mother-infant follow up.
