Background The Millennium Development Goals call for two-third and three-quarter reductions in Perinatal Mortality Rates and Maternal Mortality Ratios. The main strategy towards achieving these reductions is to increase access to skilled attendance. However, it cannot be confirmed that all health professionals are skilled in managing women in labour, nor that they are functioning in enabling environments. To measure the provision of skilled attendance, this study was undertaken in five Level 1 Hospitals in the uThungulu Health District of KwaZulu-Natal. The objectives of the study were: 1. To establish perinatal outcomes for each Level 1 Hospital in uThungulu Health District. 2. To evaluate the quality of intrapartum care provided in Level 1 Hospitals in uThungulu Health District. 3. To evaluate the obstetric knowledge of health workers attending births in Level 1 Hospitals in uThungulu Health District. 4. To evaluate the obstetric skills of health workers attending births in Level 1 Hospitals in uThungulu Health District. 5. To evaluate the environment in which births are attended in Level 1 Hospitals in uThungulu Health District. 6. Compare the quality of care, the knowledge, skills and environment with perinatal outcomes. Methods Perinatal outcomes (PNMR, FSBR, ENNDR and PCI) were calculated for each hospital; maternity case records of women who have delivered in these Level 1 Hospitals were audited to assess the quality of intrapartum care; obstetric knowledge and skills of midwives were assessed; as was the enabling environment within which midwives worked, which included a measurement of their workload. A correlation between perinatal outcomes and the quality of intrapartum care, knowledge and skills and the enabling environment was performed to determine whether variables were associated. Results The overall PNMR for five hospitals in uThungulu Health District was 31 per 1000 births. Three hospitals demonstrated PNMRs below 30 per 1000, while the other two showed rates above 45 per 1000. The combined FSBR for the five hospitals was 6 per 1000 births, the combined ENNDR was 12 per 1000 live births. The PCI in all hospitals ranged between 3 and 4. An audit of maternity case records revealed that all hospitals have a high overall mean percentage score per record. However, analysis of subsets showed good performance in recordings on the labour graph, but poor performance in the admission assessment and in the management of labour. The Kruskal-Wallis Non-Parametric Test showed a statistically significant difference in overall scores amongst hospitals (p=0.01), suggesting differences in performance in all five hospitals in terms of the quality of care provided. Overall, all hospitals scored poorly on tests of obstetric knowledge and skills. There were no statistically significant differences in the overall knowledge median scores and subsets median scores amongst hospitals (p=0.07), indicating that all five hospitals performed on a similar level in terms of obstetric knowledge. However, all hospitals performed differently in relation to obstetric skills, as there was a statistically significant difference in the overall skill median scores amongst hospitals (p=0.002). Three hospitals met the enabling environment standard. All hospitals but one scored poorly on referral, and the availability of supervision on both shifts. One hospital scored poorly on drugs and supplies. Overall no hospitals reported the presence of all the elements of the enabling environment. Three hospitals had acceptable workloads. No association could be detected between variables. However, there were trends that can be traced in different hospitals. Conclusions In South Africa, from the Demographic and Health Survey, 84% of deliveries are assisted by skilled attendant. While an attendant may be present, one cannot say that skilled attendance has been provided, as it has been shown for uThungulu Health District. / Thesis (MMed.)-University of KwaZulu-Natal, Durban, 2010.

Objective To conduct an evaluation of the pilot implementation of the World Health Organization Health Promoting Hospitals initiative and its self-assessment tool in public hospitals in KwaZulu-Natal in 2004/2005 Study design This evaluation utilised a cross-sectional design that incorporated both qualitative and quantitative research methods. Main measures Throughout the Health Promoting Hospital pilot project the opinions and responses of those with a legitimate interest in the initiative were monitored. Data collection methods utilised in this evaluation included participant observation, the World Health Organisation metaevaluation questionnaire, records of workshops and feedback meetings and secondary analysis of all data collected by the six pilot hospitals during the implementation of the project in KwaZulu-Natal. Results Major constraints were found to be time, human and financial resources, lack of training and expertise and insufficient support for the project. The self-assessment tool was found to be insufficiently adapted and not all outcomes were found to be reliable and useful. Despite this, institutional staff found the Health Promoting Hospital project to be capacity building and morale boosting. Relationships between health service levels improved. All hospitals who participated recommended that other hospitals become Health Promoting Hospitals. Conclusion If the World Health Organisation Health Promoting Hospital initiative with its selfassessment tool is to be rolled out to the rest of KwaZulu-Natal province, then substantial changes have to be made to the process. Amongst these are: further adaptation of the selfassessment tool, improved methods of data collection, provision of sufficient resources and increased and sustained provincial support for the project. In addition it is imperative that outcome and impact evaluations be done. / Thesis (M.Med.)-University of KwaZulu-Natal, 2008.

Background Recent gains in child survival are being threatened by the RN epidemic. Monitoring child mortality rates is essential to understanding the impact of the epidemic, but is constrained by a lack of data. A community-based survey was used to determine child mortality rates in a rural area with high RN prevalence, located in the Rlabisa subdistrict of the KwaZulu-Natal Province, South Africa. ii. Methods The study was conducted between 1 January 2000 and 31 December 2002 on deaths in children under the age of 15 years. Children were followed up through 4-monthly home visits. Cause of death was ascertained by verbal autopsy. Rates were calculated using Poisson methods. iii. Results Infant and under-5 mortality ratios were respectively, 59.6 and 97.1 deaths per 1000 live births. Infant and under-5 mortality rates were, respectively, 67.5 and 21.1 deaths per 1000 child-years. RN/AIDS was attributed to 41% of deaths in the under-5 age group, with a mortality rate of 8.6 per 1000 person years. Lower respiratory infections caused an estimated 24.9 deaths per 1000 person years in children under 1 year of age. iv. Discussion In rural South Africa, infant and child mortality levels are high, with RN/AIDS estimated as the single largest cause ofdeath. Improving the coverage of interventions known to impact on child mortality is required urgently. / Thesis (M.Med.)-University of KwaZulu-Natal, Durban, 2007.

South Africa is one of the six southern African countries where the HIV levels for childbearing women are 20% or higher. In South Africa, like most countries, behaviours such as multiple sexual partners, unprotected sex and drug use expose individuals to the risk of HIV infection and drive the HIV epidemic. Thus, research on sexual risk behaviours associated with HIV/AIDS is vital in identifying target groups at risk for HIV. Previous research has shown a link between substance use and sexual risk behaviour however in South Africa research within this field is still evolving. Furthermore, research on substance abuse among women in South Africa is limited. In the light of increasing HIV infection in women and the possible influence substance use has on sexual risk behaviours including HIV, exploring the association between substance use and sexual risk behaviours among women would provide valuable information. Socio-cultural and situational factors are explored within substance use and sexual risk behaviours as women's lives occur with realm of individual, family and community. The sample was drawn from an Alcohol and Drug Rehabilitation Centre situated in the Durban area. Study participants included Black/African, White, Indian and Coloured women who were admitted to the treatment centre for alcohol abuse. One focus group discussion and six in-depth interviews were conducted with women to understand the socio-cultural and situational context of substance abuse and sexual risk-taking behaviours (including HIV/AIDS). Substance abuse emerged from women's lack of coping mechanisms to deal with poor relationships and lack of employment which led to financial dependence on their partners. Women reported that within their settings, alcohol can be related to sexual risk behaviours because alcohol tends to lead to unsafe sexual behaviours. Women reported that alcohol use facilitates intimacy and rapport between couples thus some women tended to consume alcohol. Women reported that knowledge of safe and unsafe sex is known however implementation is difficult because condom use requires her partner's co-operation. Women were financially and emotionally dependent on their partners, social norms which determine women's role in society and sexual relationships governed their behaviour. Partner violence was a common feature among women which impacted on women's ability to negotiate condom use. The paper discusses the intrapersonal, interpersonal and contextuall situational factors that influence substance use and sexual risk behaviours in these women's lives. / Thesis (M.Med.)-University of KwaZulu-Natal, Durban, 2008.

Introduction: The high prevalence of HIV in South Africa was confirmed by Department of Health (2005) which reported an HIV prevalence rate of 40.7 percent amongst antenatal clinic attendees at public facilities in KwaZulu-Natal in 2004. Abstinence is one of the strategies used by many different cultures where young unmarried people are encouraged to abstain from sex until marriage, to prevent young girls from getting pregnant and acquiring sexually transmitted infections (STIs). Aim: The aim of this study was to investigate African rural high school learners' choice of sexual abstinence and to compare abstinent versus non-abstinent African rural high school learners in order to be able to develop tailored educational messages. Abstinence was defined as not having penetrative sex, since this is the accepted definition of abstinence in Zulu culture. Objectives: a) To investigate the prevalence of abstinence from sexual intercourse amongst African rural high school learners, b) To assess demographic, psychosocial, and economic determinants of abstinence from sexual intercourse, c) To make recommendations about abstinence interventions. Method: A descriptive cross-sectional study was carried out in a rural area (Ugu District in southern KwaZulu-Natal). One class of Grade 9 learners, ages 14-20 years, was selected from each often randomly selected rural high schools. An anonymous selfreporting semi-structured questionnaire used the I-Change model to investigate demographic and economic information, attitudes, social influences, self-efficacy and intentions towards sexual abstinence. Chi square and T-tests were used for bivariate analysis and Logistic regression was used to develop a model for abstinence from sexual intercourse. Results: A total of 454 learners participated with a mean age of 16.76 years (SD 1.41) age range 14-20 years. Of the sample 208 (45.8%) were male and 246 (54.2%) female. The majority were Christian (84.6% (n=384)) and of this population, 28.3% (n=127) reported that they had 'ever had sex'. Furthermore, 24.5% (n=91) of learners reported that they were currently sexually active. Fifty six percent (n=252) of learners reported that they abstained from sex. When comparing learners reporting abstinence (n= 252) with those not abstinent (n= 202), abstinent learners were significantly more often females, who had never had sex (p / Thesis (M.Med.)-University of KwaZulu-Natal, Durban, 2007.

In 1990 the Department of National Health and Population Development of South Africa launched a nationwide immunisation coverage campaign targetted mainly at measles. In order to measure the effect of the campaign on vaccination coverage rates for children pre- and post- campaign vaccination coverage surveys were performed using a modified EPI technique, stratified for race and urban/rural residence. The results in Natal/KwaZulu showed no significant changes in vaccination coverage rates as documented by Road-to-Health cards for any race, although the trend was towards a slight increase. The results bring into question the effectiveness of immunisation campaigns as a strategy for raising vaccination coverage levels, and having a sustained impact on the incidence of measles. Alternative strategies, such as the strengthening and expansion of existing primary health care services, and changes to the immunisation schedule for measles, should be considered. / Thesis (MMed.)-University of Natal, Durban, 1992.

South Africa has had one of the fastest growing HIV epidemics in the world and almost 30% of women attending public antenatal clinics (ANC) are currently infected with the virus. But as the epidemic is starting to level off and antiretroviral therapy (ART) is becoming increasingly available, few methods exist to determine the impact of ART or other interventions on the epidemic in South Africa. This thesis explores the epidemiology and dynamics of HIV infection and investigates the potential impact of ART. Methods Total and age-specific prevalence data are analysed in time and space and are used to investigate patterns of infection in men and women, urban and rural, and low and high risk populations. Dynamical models are developed to estimate incidence from age-specific prevalence and trends over time and are compared to laboratory-based estimates of recent HIV sero-conversion. Incidence is estimated in different populations in South Africa. A dynamical model is developed to estimate the impact of ART on the future course of the HIV epidemic. Results HIV prevalence varies geographically and by age, sex and race. The average female-tomale HIV prevalence ratio is 1.7 and prevalence peaks at an older age among men than women. The age at which prevalence peaks among women has increased from 23.0 to 26.5 years between 1995 and 2002. Four patterns of infection are identified: among pregnant women attending ANCs, among men and women in the general population, and among migrant workers. HIV incidence among ANC attendees peaked in the mid to late 1990s (at 6.6% per year nationally) with variation between provinces. Current estimates of HIV prevalence and incidence among the general population in South Africa (aged 15-49 year) are 18.8% and 2.4% per year, respectively. Age-specific incidence estimates from dynamical models and laboratory methods are in good agreement provided the window period for the laboratory method is increased. Over the next ten years the provision of ART could avert 1 to 1.5 million deaths depending on whether it is provided when the CD4 cell count falls to 200 or 350 cells/ul. By 2015 about 1.1 million people will be receiving ART but this will have little impact on the incidence of HIV and scaling up of prevention efforts remains urgent. Conclusions The thesis explores some of the determinants and patterns of HIV prevalence and incidence in South Africa in order to find better ways to manage the epidemic of HIV, monitor changes and evaluate progress in control efforts. In order to fight the epidemic we need to mobilize the best possible science in support of those people and communities affected by the epidemic. / Thesis (M.Med.)-University of KwaZulu-Natal, Durban, 2007.
