Item Blurred policy spaces and grey areas in-between: exploring policy responses to cross-border migration and antiretroviral therapy treatment continuity in Johannesburg and Vhembe(2017) Vanyoro, Kudakwashe PaulBackground: Policy responses to communicable diseases and other noncommunicable ones in South (ern) Africa have not adequately engaged with mobility. While Southern African Development Community member states have all adopted clear policies and programmes to deal with communicable diseases for their population in South Africa and elsewhere, deliberately, these do not extend to non nationals. In South Africa, there is a perception that many health care workers are not aware of national health policies and legislation that affect their practice, which leads to poor outcomes. But, in reality, a number of polices and guidelines are incomplete or inapplicable to non nationals, making frontline discretion unavoidable. Objectives: This study mainly sought to understand the practices that frontline health care workers adopt to navigate a space of blurred policy and the “grey areas inbetween” (McConnel, 2010), in relation to migration and antiretroviral treatment, using bottom-up policy analysis, namely “street-level bureaucracy” (Lipsky, 2010) as an analytical tool. Methods: Qualitative methods were used including policy review, literature review, in-depth interviews with frontline health care workers and participant observation. Findings: Empirical research in Vhembe district and Johannesburg found that in spite of several institutional challenges, health care workers were providing health care services and antiretroviral treatment to various categories of non-nationals reliant on public health care, albeit sometimes with some difficulties. But, the difficulties they faced in providing antiretroviral treatment were policy and systems related, in that, those that had a hard time accessing treatment did so because they were not in possession of identity documents, required referral letters or spoke non-native languages in the absence of translation services. This thesis illustrates the various innovations frontline health care workers employed to address these challenges. It demonstrates that health care workers discretion plays a crucial role in health care delivery, and there is need to recognise the importance of informal elements such as human relationships, communication networks, leadership and motivation towards the policy function of the country’s health system. It concludes that the informal practices of frontline health care workers ought not only to be recognised but also strengthened where possible.Item Outcome of the antiretroviral treatment intervention in Mankweng(2016) Ledwaba, Ramatsobane JohannaThe purpose of this research was to assess outcomes of the antiretroviral treatment intervention in Mankweng. The antiretroviral treatment intervention was conceived with the aim to reduce HIV transmission through viral load suppression. Literature has shown that viral load is used as a tool to measure the performance of the intervention and studies on viral load outcomes in rural settings of Limpopo are limited. For this reason, the research was focused on viral load suppression with the aim of (1) determining the proportion of adults with viral load suppression among people taking antiretroviral treatment for 12 months, and (2) identifying factors associated with failure to achieve viral load suppression among people on antiretroviral treatment for 12 months. Binomial logistic regression model was used to identify factors associated with failure to suppress viral load. This study used the theory of change to interpret its findings as well as theories of behavioural planning and self-regulation models to understand the logic that underpins the theory of change. The findings revealed that the majority (78%) of adults achieved viral load suppression, and a quarter of the individuals failed to suppress the viral load. There was no significant difference in baseline characteristics between people who achieved viral load suppression and those who did not. In addition, males, with a low CD4 and opportunistic illnesses when in the primary disease stages were more likely to fail to suppress the viral load. Moreover, people who were initiated on a 3-pill containing treatment and do not have social support were also likely to fail to achieve viral load suppression. Although the study showed a trend of likelihood towards failure to achieve viral load suppression, the estimates were not statistically significant. Theoretical arguments from this study suggest that failure to achieve viral load was attributed to poor adherence to treatment. This is supported by the logic that underpins the theory of change, in which the assumption of adherence was possibly violated. However, the results chain framework highlighted that the implementation of the intervention was effective as it led to good outcomes and an effective intervention. Drawing all this together, the study highlights the need for intensified adherence counseling during treatment in order to improve the performance of the intervention.
