Indoor air quality has become an important health concern due to the number of indoor pollutants and the realization that even minimal exposures to volatile organic compounds may produce direct or indirect adverse health outcomes. Young people are most vulnerable to these poisonous chemicals as they spend much of their times indoors at homes, schools, nurseries and in day care centers. Exposure to volatile organic compounds indoors has been related to asthma and other respiratory symptoms. The adverse effects of air pollution on respiratory health in South Durban have been described in a number of studies. In 2000, a study in the South Durban Basin at Settlers Primary School demonstrated both a high prevalence of respiratory diseases amongst schoolchildren as well as an association between ambient air pollutants and other adverse health outcomes. The South Durban Health Study subsequently undertook a health risk assessment and an epidemiological study investigating this association further on behalf of the eThekwini Municipality. The study highlighted that relatively moderate ambient concentration of N02, NO, PMIO and S02 were strongly and significantly associated with a reduction in lung function among children with persistent asthma. Moreover, attending primary school in South Durban was significantly associated with increased risk from persistent asthma when compared to schools in North Durban. METHODS The descriptive study measured the total volatile organic compound levels within selected homes and schools of asthmatic children in South and North Durban. Recommendations for reducing or mitigating indoor total volatile organic compound exposures were made. The study involved a secondary analysis of data obtained from the South Durban Health Study. The monitoring for total volatile organic compounds within homes and classrooms was undertaken using passive samplers during a 72-hour period and analyzed using a gaschromatography/ mass spectrometry method. Temperature and humidity was assessed using temperature and humidity sensors. Statistical analysis was performed using SPSS version 13. The dataset comprised 140 total volatile organic compound samples from homes and 14 from classrooms. Total volatile organic compounds were measured in microgram per cubic meter (g/m3), temperature in degrees Celsius and relative humidity in percentage of moisture. RESULTS Total volatile organic compounds with levels in households ranging from 17g/m3 to 1440g/m3 and in classrooms ranging from 48g/m3 to 5292g/m3 were measured. The mean levels detected were significantly different in homes and classrooms / Thesis (MMed.)-University of KwaZulu-Natal, Durban, 2008.

Introduction. The demand for comprehensive Human Immunodeficiency Virus (HIV) and Acquired Immunodeficiency Syndrome (AIDS) services is greater than the available supply, particularly for the provision of antiretroviral therapy. The resulting bottleneck in service delivery has considerable implications for people living with HIV and for resource management. Aim. The purpose of this research was to investigate loss-to-care and associated variables of adult HIV-infected people who were eligible for antiretroviral therapy, from July 2004 to December 2007 at Sinikithemba HIV Clinic in Durban, KwaZulu-Natal. Methods. An observational descriptive and analytic cohort study design was used. Secondary data sourced from Sinikithemba were collated. All HIV-infected adults, 15 years and older when registered on the TrakCare database, who were eligible for antiretroviral therapy were included in the study. Data were extracted to describe the preparation of HIV infected adults who were eligible for antiretroviral therapy. Variables were first summarised and described before the confirmatory analytic steps were taken to measure associations at the p<0.05 significance level. Results. Of the 10 424 HIV-infected adults registered at Sinikithemba, 5470 (52%) were eligible for antiretroviral therapy from July 2004 to December 2007 and 2979 (54%) of these were lost to care prior to initiating antiretroviral therapy. Six exposure variables were significantly associated with this loss-to-care, (gender, baseline CD4 count, pre-eligibility care, antiretroviral therapy delay, preparation step and waiting time). These variables remained significantly associated with loss-to-care even after controlling for confounding with logistic regression. Discussion and Recommendations. With the rapid scale-up of antiretroviral therapy programmes, the outcome of those people living with HIV lost to care before commencing therapy have not been adequately documented. This large cohort enrolled over three-and-a-half years demonstrates that the loss-to-care prior to initiation of antiretroviral therapy is a significant problem that needs to be further investigated. Focusing retention strategies at the pre-antiretroviral therapy stage of HIV care will improve overall programme outcomes. / Thesis (M.Med.)-University of KwaZulu-Natal, Durban, 2011.

International mass sports gatherings like the FIFA (Federation Internationale de Football Association) World Cup Soccer and Olympics can cause great challenges to local healthcare systems and emergency medical services. History has shown that disasters do occur during these events, whether on a small or large scale. Disaster Management Practitioners from the public health perspective widely recognize that poor planning and a range of other underlying factors, create conditions of vulnerability. These result in insufficient capacity or measures to reduce hazards’ potentially negative consequences. The eThekwini District has to be prepared in the event of a mass disaster. Pre-empting and planning for disasters will lead to the safety and security of our citizens. The aim of this study was to undertake a baseline survey (in a total number of eleven public sector hospitals) to assess the state of hospital readiness, medical preparedness, and emergency care in preparation for the 2010 FIFA World Cup Soccer in the eThekwini District. A general assessment tool in the form of a standard questionnaire, and a walkthrough visit with a checklist, was used to collect data. There is no previous study conducted at the eThekwini District to assess requirements for an international event in terms of a mass disaster. South Africa is a developing country, and this was the first time any developing country had hosted a sporting event on such a large magnitude thus there are no international standards on sports disaster management by any other developing countries to generalise to eThekwini District. The current disaster management operational plan that is being used for the World Cup is based on a United Kingdom integrated management philosophy tool. The study herein adopted a public health approach and incorporates the Yokohama Strategy within its tool along with the use of HMIMMS and MIMMS in the assessment of the clinical criteria. The perceived minimum requirements suggested by the hospitals and a Provincial Task Team, from the Provincial Health Disaster Management office, was used as a guideline. The study showed that although disaster plans and policies are in situ, there still exists a need for resources to be directed toward skills training, attraction and retention of healthcare professionals, revitalisation of emergency and theatre areas and the commissioning of more isolation units. The results of the study would enable the District Office to note any shortcomings and lack of resources in public sector hospitals. The study outcome would be important for the implementation of any strategic planning to aid the hospitals in preparation for mass disasters that may occur during the 2010 FIFA World Cup Soccer. / Thesis (M.Med.)-University of KwaZulu-Natal, Durban, 2010.

The physical, psychological and social development of school children has been neglected - partly because they were seen as healthy "survivors" of the ravages of childhood illnesses, and partly because of the way in which health services are organized (such as the traditional under-five maternal and child health (MCH) services and the curative PHC clinic services). From the age of five years children undergo rapid and profound bio-psycho-social development, to emerge in adolescence as the next generation of leaders and workers. Securing their future growth and development is vital for any society to be economically and socially productive. A substantial body of national and intemational literature has recognised the detrimental impact of helminthic infections and micronutrient deficiencies on the physical and psychological health and development of school children; which requires appropriate nutritional interventions. Concern has been expressed that these adverse biological, physical and social deprivations have a cumulative impact on several dimensions of children's growth. Most important, apart from stunting physical growth, is the inhibition of educational development of school children. Recent evidence strongly suggests a powerful interaction between physical and psychosocial growth and development of children. Inhibition of either component of a child's well-being has adverse implications. Conversely, investments in the physical and psychological development of children are likely to generate substantial health and educational benefits and are a worthy investment to secure a healthy future generation. In summary, there are a number of reasons for, and benefits of, investing in school-based health and nutrition interventions. They are likely to improve learning at school and enhance educational outcomes; create new opportunities to meet unfulfilled needs; redress inequity; build on investments in early child development and promote and protect youth and adolescent development. Health and nutrition interventions such as school feeding programmes, micronutrient supplementation and deworming aim to improve primary outcomes of macro and micro-nutrient deficiencies, parasitic and cognitive status; as well as secondary outcomes of developing integrated comprehensive school health policies and programmes. This rationale served as the conceptual framework for this study. This theoretical framework views improvements of the health, nutritional, cognitive and scholastic development status of school children as the primary focus of policies, strategies and programmes in the health and education sector. This focus constitutes the central core of this thesis. Optimum social development requires investments in both the health and educational development of school children, so as to maximise the synergies inherent in each sector and to operationalise national and international strategies and programmes. As part of the larger RCT study a comprehensive nutritional, health and psychological profile of rural school children was established through a community-based cross-sectional study. Eleven schools were randomly selected from the Vulamehlo Magisterial District in southern KwaZulu-Natal (KZN). Within each school, all Standard 1 pupils, aged between 8 - 10 years, were selected giving a final study sample of 579 children. Some of the observed prevalence's were stunting (7.3%), wasting (0.7%), anaemia (16.5%) (as measured by haemoglobin below 12 g/dl), vitamin A deficiency (34.7%) (as measured by serum retinol below 20 ug/dl) and serum ferritin below 12ng/ml (28.1%). This study established that micronutrient deficiency, parasitic infestations and stunting remain significant public health problems among school-aged children in South Africa. Combining micronutrient supplementation and deworming are likely to produce significant health and educational gains. To determine the impact of single and combined interventions (anthelminthic treatment and micronutrient supplements) on nutritional status and scholastic and cognitive performance of school children, a double-blind randomised placebo controlled trial was undertaken among 579 children 8-10 years of age. There was a significant treatment effect of vitamin A on serum retinol (P<0.01), and the suggestion of an additive effect between vitamin A fortification and deworming. Vitamin A and iron fortification also produced a significant treatment effect on transferrin saturation (P<0.05). Among the dewormed group, anthelminthic treatment produced a significant decrease in the prevalence of helminthic infections (P<0.02), but with no significant between-group treatment effect (P>0.40). Scholastic and cognitive scores and anthropometric indicators were no different among the treated or the untreated children. Fortified biscuits improved micronutrient status among rural primary school children; vitamin A combined with deworming had a greater impact on micronutrient status than vitamin A fortification on its own; while anthelminthic treatment produced a significant reduction in the overall prevalence of parasite infection. The prevalence's of Ascaris lumbricoides, Trichuris trichiura and Schistosoma haematobium declined significantly sixteen weeks post-treatment. The levels of both prevalence and intensity in the untreated group remained constant. The cure rates over the first two weeks of the study were 94.4% for Ascaris lumbricoides, 40% for Trichuris trichiura, and 72.2% for Schistosoma haematobium. The benefits of targeted school-based treatment in reducing the prevalence and intensity of infection supports the South African government's focus of using school-based interventions as part of an integrated parasite control programme. These strategies and programmes were found to be consistent with the recommendations of WHO and UNICEF. The nutritional transition facing developing and middle-income countries also has important implications for preventive strategies to control chronic degenerative diseases (Popkin B, 1994; WHO 1998; Monyeki KO, 1999). This descriptive study, comparing BMI data of school children over three time periods, found a rising prevalence of overweight and obesity among South African school children. Obesity as a public health problem requires to be addressed from a population or community perspective for its prevention and management. Environmental risk factors such as exposure to atmospheric pollution remain significant hazards for children. Lead poisoning is a significant, preventable risk factor affecting cognitive and scholastic development among children. The prevalence of elevated blood lead (PbB) levels in rural and semi-urban areas of KwaZulu-Natal (KZN) as well as the risk factors for elevation of PbB among children in informal settlements were examined. This study investigated over 1200 rural and urban children in two age groups: 3-5 and 8-10 years old. Average PbB level in peri-urban Besters, an informal settlement in the Durban metropolitan region, was 10 ug/dl with 5% of the children showing PbB level of greater than 25 ug/dl. By comparison, average PbB value in Vulamehlo, a rural area located 90-120 km from Durban, was 3.8 ug/dl and 2% of the children's PbB levels were greater than 10 ug/dl. Since the cognitive and scholastic performance of school children was a primary outcome measure in this study, it was important to explore other factors that influenced this variable. The performance scores of all four tests in the battery, among the cohort of a thousand rural and urban children, were in the lower range. The educational deficit identified in this test battery clearly indicates the impact of the inferior "Bantu" educational system that African children have experienced in South Africa. Aspects of the School Health Services that were investigated in this descriptive study included the services provided and their distribution; assessment of health inspection; health education and referral processes undertaken by the School Health Teams; perceptions of managers, providers and recipients of the service; as well as the costs of the provision of the service in KwaZulu-Natal. In KwaZulu-Natal, there were School Health Teams In all the 8 health and education regions in the province. In total, there were 95 teams in the province, consisting of nearly 300 staff members. The School Health Teams were involved in a wide range of activities - 74% of all teams were involved in health inspection and 80% were involved in health education. The total annual cost of delivering School Health Services in the province in 1995 was estimated to be approximately R8 750 000. Given the rise of HIV and AIDS in the province, School Health Services need to play a central role not only in prevention, but also in assisting with the acceptance of HIV-positive children within schools. It is recommended that the current and future draft SHS policy guidelines be approved by the relevant authorities for immediate implementation. Districts should consider developing "Health Promoting Schools", with School Health Teams being a central resource. This thesis has explored several aspects of the epidemiological profile of school children in rural and urban settings in KwaZulu-Natal. It has established that school children are exposed to a range of risk factors ranging from nutritional deficits, parasitic infections, atmospheric lead poisoning and a rising prevalence of overweight. All of these risk factors may compromise their physical, psychological and social development. A number of health interventions have been identified, which have the potential to address these problems. Such investments are essential to secure the health of future generations. / Thesis (M.D.)-University of Natal, Durban, 2001.

Introduction Tuberculosis (TB) is a major cause of death worldwide. Control of Tuberculosis is a serious challenge to global health. A new and potentially devastating threat to TB control is the emergence of multi-drug resistant TB (MDR-TB). South Africa was ranked fourth among the countries with the highest number of confirmed MDR-TB cases. Aim The aim was to investigate the annual MDR-TB prevalence and associated risk factors for MDR-TB from 2001 to 2007 at the Prince Cyril Zulu Communicable Disease Centre. To investigate previous TB treatment duration, previous TB treatment outcome, and duration of previous TB treatment interruption in a subgroup of patients who were previously treated for TB. To determine the average length of time from diagnosis of TB to diagnosis of MDR-TB and commencement of MDR-TB treatment. Methods An observational analytic nested case-control study design was used. All patients who were diagnosed with pulmonary TB and who had a sputum culture performed between 2001 and 2007 were included in the study. The cases were all MDR-TB cases diagnosed on sputum culture between 2001 and 2007. The controls were drug susceptible TB cases which had a sputum culture done at diagnosis, and were diagnosed in the same month as the MDR-TB case Results There were 10 205 sputum cultures performed from 2001 to 2007. MDR-TB was found in 445 patients. An increase in the prevalence of MDR-TB occurred in 2007, due to a significant increase in prevalence among new TB cases. The MDR-TB prevalence was 11.7% among new TB cases and 4.7% among previously treated TB cases in 2007. There was no significant association between demographic characteristics and MDR-TB. Previous TB treatment failure and a duration of previous TB treatment of greater than 32 weeks was found to be significantly associated with MDR-TB. The median time from TB diagnosis to MDR-TB diagnosis was 98 day and from MDR-TB diagnosis to MDR-TB treatment 10 days. Discussion Delays in the diagnosis of MDR-TB, long waiting times before MDR-TB treatment commencement and lack of isolation have contributed to the spread of primary MDR-TB and was most likely responsible for the increase in prevalence of MDR-TB among new TB cases. Recommendations It was suggested that a sputum specimen should be obtained for culture and sensitivity from all new TB patients in areas which have an MDR-TB prevalence of greater than 3% among new TB patients. Ensure patient education on basic infection control measures. Improve MDR-TB diagnosis and reduce waiting times for MDR-TB treatment. / Thesis (M.Med.Sc.)-University of KwaZulu-Natal, Durban, 2011.

ABSTRACT This study focuses on the implementation strategy of free health care policy for disabled persons at hospital level in KwaZulu-Natal. Since the introduction nationally, in 2003 of free health care policy for disabled persons, no evaluation has been conducted in KwaZulu- Natal to inform health service managers and the KwaZulu-Natal Department of Health on the implementation of this policy. A provincial implementation strategy is needed for effective implementation of the policy. To date, no such provincial implementation strategy is available and the lack of an implementation strategy for this policy motivated this study. METHODS An exploratory qualitative study design was implemented to elicit information from health service providers and representatives of persons with disabilities to inform the development of an implementation strategy for the free health care policy for disabled persons at public hospitals in KwaZulu-Natal. Data was collected through interviews and focus group discussions. Data was analysed by utilising a thematic approach. RESULTS Respondents reported a variety of understandings with regard to policy context of the Free Health Care Policy for disabled persons, policy content in terms of purpose and eligibility, policy implementers and their roles in implementing the policy, and the implementation process of this policy at state hospitals of KwaZulu-Natal. CONCLUSION There is limited understanding of the Free Health Care Policy among some health service personnel and some disability groups, and this may have contributed to the erratic and poor implementation of the policy at public hospitals in KwaZulu-Natal. Factors necessary for policy implementation such as a communication strategy, guidelines for implementation, assessment of availability of resources, training of implementers, monitoring and evaluation strategy are crucial for effective implementation of any policy including the Free Health Care Policy for disabled persons. / Thesis (M.Med.Sc.)-University of KwaZulu-Natal, Durban, 2013.

Background HIV infection continues to be a challenge in South Africa with new infections reported at alarming rates. Health Care Workers (HCWs) who are nurses consequently have frequent contact with HIV positive and TB co-infected patients. During this contact their counselling behaviour is influenced by their knowledge, beliefs and attitudes about HIV and AIDS, STIs and TB (HAST) and may influence provision as well as the quality of HAST counselling behaviour. Aim The aim of the study was to assess eThekwini Municipality Health Care Workers’ knowledge, beliefs and attitudes regarding counselling behaviour for HAST and to make recommendations based on the findings of this study. Methods A descriptive cross sectional study design was used in which data about HAST counselling behaviour were collected using self administered questionnaires. The study population was all the nurses working at eThekwini Municipality Health clinics that were on duty at the time of the study and excluded those nurses who were absent or on leave during the period of data collection. Informed consent was signed by each respondent. Data were captured using SPSS version 14 and univariate, bivariate and multivariate analysis was undertaken. The level of significance was P<0, 05. Results The HCWs were well informed regarding counselling behaviour for HAST. HCWs with university education scored higher than those with college level of education but there were no statistically significant differences between the HCWs with the university education and those with college education. However some HCWs’ attitudes and beliefs about poverty were negative and may not be helpful in improving a patient’s health. Results showed that some HCWs’ negative attitudes about HAST counselling resulted from fear of HIV and or TB infection. Age and the level of education showed statistically significant association with beliefs. Older, better educated HCWs with a university education scored higher for knowledge for HAST counselling behaviour. There was no statistical significant difference found between HCWs who see less than 100 patients per day and those who see more than 100 patients per day. Conclusion The findings of the study show that HCWs were well informed regarding counselling behaviour for HAST, even though some HCWs have negative attitudes which are not supportive which need to be addressed. Recommendations It is recommended that HCWs receive continuous training in order to address the negative attitudes about counselling behaviour for HAST. / Thesis (M.Med.Sc.)-University of KwaZulu-Natal, Durban, 2012

Introduction Willingness to participate in clinical trials is a crucial element in recruitment of suitable participants for intervention trials. Measurement of willingness to participate assists in determining community preparedness for clinical trials, such as HIV vaccine trials. Therefore, researchers have developed a Clinical Research Involvement Scale (CRIS) to assess willingness to participate modelled on the Theory of Reasoned Action. The CRIS was tested in the USA and was noted that it would benefit from additional testing in other populations. Aim The purpose of this study is to determine whether racial differences exist in willingness to participate and explore potential factors associated with willingness to participate in HIV prevention research. Methods A cross sectional analytic study was conducted. The CRIS was administered to university students aged 18-45 at the University of KwaZulu-Natal in South Africa. The CRIS was administered online with a demographic questionnaire to facilitate evaluation of possible associations between willingness to participate and age, gender, relationship status, parity, religion, education status, student status, employment status and access to private health care. Participation was once-off at the time of completing the scale. Results The study enrolled 636 participants, two thirds being female. An effective sample size of 509 was considered for analysis after data was cleaned for accuracy and completeness. The results indicated that all students across all race groups were willing to participate in HIV prevention research. However, when considering factors that affected willingness to participate, statistically significant differences were noted. Based on the differences amongst these factors, Black students expressed greater intention to participate compared to White and Indian students. The CRIS was deemed a reliable instrument in this population; however in its current structure it did not show strong validity. Validity improved if the factors of motivation to comply and outcome evaluations were removed in this population. Discussion The study findings are specific to students of the University of KwaZulu-Natal and cannot be generalized to other populations. The racial differences in factors that affect willingness to participate indicate differences in risk perception and seeking access to better quality healthcare. Recommendations The CRIS should be used in other student populations to assess its validity. (350 words) / Thesis (M.Med.Sc.)-University of KwaZulu-Natal, Durban, 2013.

Introduction e-Learning has been integrated and implemented in education and training to the level that it is now a well-established global practice. If used judiciously, e-Learning is a tool that enables active, individual and flexible learning. When integrated into medical education, it offers features that allow lecturers to be not merely content distributors, but also facilitators of learning. Aim The aim of this study was to assess the readiness of students to make the shift from traditional learning, to the technological culture of e-Learning. Methods An observational, cross-sectional, analytical study design was used and data was collected using a validated questionnaire. The sample comprised of all students enrolled in the first year nursing programme at the Durban University of Technology registered for anatomy and physiology in 2013. Informed consent was obtained from each participant prior to conducting the study. Results Three quarters (77/101 76%) of the participants were females. The psychological readiness score was noted to be high in the “could be worse” category (pre-72%, post- 64%). The technological readiness score was noted to be in the “dig deeper” category (pre- 58%, post- 65%) whilst the equipment readiness score fell in the e-Learning “not ready category” (pre- and post- 68%). Discussion The Chapnick Readiness Score Guide was used to analyse psychological, technological and equipment readiness. e-Learning has been identified as a multi-disciplinary field, which is dominated by information technology. Technological and equipment readiness factors of e-Learning are easier to resolve than the psychological readiness factor. Recommendations Although e-Learning could be a key tool in nursing education, a few factors require attention before it can be effectively implemented in this tertiary level education facility. / Thesis (M.Med.Sc.)-University of KwaZulu-Natal, Durban, 2014.

Introduction Since the 1994 change in power in South Africa, there have been many necessary changes in health legislation (HL), in accordance with the principles enshrined in the Constitution, Such changes have been recognized as being both complex and fraught with stakeholder interests. There is a perception that private family practitioners (FP) generally harbour negative attitudes towards HL that has been brought into effect in recent years. It is also possible that FP, in general, lack knowledge regarding HL. The aim of the study was to assess the knowledge and attitudes of private family practitioners (FP) to health legislation (HL) within a localized geographical area of the eThekweni Metro, KwaZulu-Natal Province. The specific objectives were: To determine family practitioners’ knowledge of health legislation. To determine family practitioners’ attitudes towards health legislation. To assess the correlation between family practitioners’ knowledge and attitudes. To compare the self-reported knowledge of health legislation with the objective assessment of knowledge and attitudes. To establish practitioners’ perceptions of the future of the profession, and of family practice in particular. Methods A cross-sectional descriptive and analytical study was performed, using a pre-tested, validated, structured questionnaire. This instrument was personally hand-delivered to each of a group of private family practitioners practising within a confined geographical area. The sample comprised of 101 family practitioners. Data were analysed using SPSS version 15.0 (SPSS Inc., Chicago, Illinois). Results The study revealed that private FP possess limited knowledge about HL and have a negative attitude in general towards HL. The mean knowledge score was 55% (standard deviation 12.2%). The mean score for attitudes towards health legislation was 46,3% (standard deviation 4.2%). The correlation coefficient between knowledge and attitudes was 0.244 (p=0.022). Therefore, there was a weak positive, but statistically significant, correlation between knowledge and attitudes. Thus, in general, as knowledge increased, so did attitudes improve and become more positive. The self reported knowledge and attitudes of FPs seemed to show some unexpected though non-statistically significant anomaly, in that FPs who considered themselves “well aware” of certain parts of HL, together with those who were “not aware”, reporting a more negative attitude towards HL than those who considered themselves to be “aware”. FPs’ perceptions of the future of the profession, and of family practice in particular, were generally reported as being reasonable to poor. Financial viability and sustainability of FP, in particular, were reported as being reasonable to poor. The attractiveness of the profession to the youth of today was reported as being poorer than in the past. However, the majority of FP held the perception that medicine as a profession was distinct as it responds to a calling to serve society at large, giving this aspect of the question a ranking of “reasonable to good”. Conclusion and Recommendations The study revealed that this group of FPs attained an overall mean knowledge score of 55% with respect to HL. FPs’ knowledge of HL requires improvement, which can be achieved through effective education and training programmes. Private FPs need to embrace the change process, but also need to be more pro-active in vocalizing their opinions. The Health Ministry and relevant authorities and policymakers need to play a greater role in creating an atmosphere that embraces and facilitates change by involving iii relevant stakeholders. Lastly, it is recommended that this study serve as a template for a broader research project involving larger numbers of participants and a wider geographical area. In addition, an intervention tool should be devised. Such a tool could take the form of a structured education programme on HL, with an associated monitoring and evaluation aspect, which would enable an assessment of the intervention programme in terms of its value and the influence it has on improving knowledge and attitudes. / Thesis (M.Med.Sc.)-University of KwaZulu-Natal, Durban, 2011.
