Magister Public Health - MPH / BACKGROUND: Namibia has generalised Human Immunodeficiency Virus (HIV) and tuberculosis (TB) epidemics. In response to the TB/HIV co-epidemics in Namibia, the Ministry of Health and Social Services approved a policy of TB/HIV collaborative activities at national level and the integration of TB/HIV services at the point of service delivery. The present study explored barriers and facilitators of integration of TB and HIV service delivery in Tsandi District Hospital, which lies in rural northern Namibia. It focused on understanding the perspectives of healthcare workers and service users on integration of TB and HIV services at the health facility. AIMS & OBJECTIVES: The study aimed to describe the barriers, facilitators, and opportunities of integrated TB/HIV service delivery in Tsandi District Hospital. The specific objectives were: to describe the staffing and support systems in place for the integration of TB/HIV care; to describe the perceptions and experiences of integrated TB/HIV care by the health care workers, management and co-infected clients; and to describe the factors that facilitate or hinder the integration of TB/HIV services in the district from the point of view of district hospital managers, health care workers and co-infected clients. METHODS: The study used a descriptive qualitative study design with semi-structured key-informant interviews conducted with five healthcare managers and senior clinicians and focus group discussions with 14 healthcare workers and five TB/HIV co-infected patients, supplemented by non-participant observation in Tsandi district hospital over two weeks between May – June 2011. Sessions were audio-recorded, transcribed, and thematically analysed. RESULTS: Several factors influenced whether and to what degree Tsandi district hospital was able to achieve integration of TB and HIV services. These are: (1) model of care and nature of referral links; (2) the availability and use of human resources and workspace; (3) the system of rotating staff among departments in the hospital; (4) the supply and mode of providing medicines to patients; (5) information systems, recording and reporting arrangements; (6) and the amount of follow-up and supervision of the integrated services. The main suggested barrier factors are: (1) poor communication and weak referrals links between services; (2) inadequate infrastructure to encourage and deliver TB and HIV care; (3) staff shortages and high workload; (4) lack of training and skills among healthcare workers; (5) financial constraints and other socioeconomic challenges; and (6) fragmented recording and reporting systems with limited data use to improve service delivery. The four main facilitating factors are: (1) positive staff attitudes towards TB/HIV integration; (2) common pool of staff managing different programmes; (3) joint planning and review of TB and HIV activities at the ARV Committee; and (4) informal task sharing to alleviate healthcare worker shortages. CONCLUSIONS: This study recommends that the district build on the current facilitators of integration, while the inhibitors should be worked on in order to improve the delivery of TB/HIV services in the district. Simple and practical recommendations have been made to address the some of the barriers at district level. It is hoped that these will inform future planning and review of the current model of care by the District Management Team.

Introduction: Despite Colombia having adopted a health system based on an insurance market, Bogota in 2004, as part of a left-wing government (elected for first time in the city), decided to implement a Primary Health Care (PHC) strategy to improve quality of life, level of population health and reduce health inequities. The PHC strategy has been implemented through the HomeHealth program by three consecutive governments over the last eight years in the context of continuous political tension stemming from differences between national and district health policies. This thesis is an attempt to provide a better understanding of the overall experience of implementing a PHC strategy in the context of a market-oriented health care system. The research aimed to evaluate results of the PHC strategy through the intervention of the Home Health program and to identify factors that have enabled or limited the on-going PHC implementation process in Bogota. Methods: This study used a combination of quantitative and qualitative methods. A descriptive analysis was performed to assess direct results of the PHC strategy in terms of progress in the Home Health program coverage and increases in health personnel ratios reaching out to poor and vulnerable groups in Bogota. A cross sectional analysis was carried out to evaluate qualities of the delivery of PHC services through the attainment of PHC essential dimensions in the network of first-level public health care facilities. An ecological analysis was performed to estimate the contribution of the PHC strategy, through the Home Health program, to improve child health outcomes and to reduce health inequalities. A qualitative multiple case study was conducted to identify contextual factors that have enabled or limited the on-going PHC implementation process in Bogota. Results: The descriptive analysis showed a notable initial increase and rapid expansion in the development of the PHC strategy between 2004 and 2007, followed by a period of slower growth and stagnation between 2007 and 2010. The cross-sectional analysis suggested that the Home Health program could be helping to improve the performance of first-level public health care facilities. Ratings assigned to PHC dimensions by different participants pointed out the need to strengthen family focus, community orientation, financial resources distribution, and accessibility. The ecological analysis showed that localities with high PHC coverage had a lower risk of under-five mortality, infant mortality and acute malnutrition as well as a higher probability of being vaccinated than low PHC coverage localities. The belonging to a high-coverage locality was significantly associated with risk reductions of under-five mortality (13.8%) and infant mortality by pneumonia (37.5%) as well as increases in the probability of being vaccinated for DPT (4.9%). Concentration curves and concentration indices indicated inequality reductions in all child indicators betwen 2003 and 2007. In 2007 (period after implementation), the PHC strategy was associated with a reduction in the effect of the inequality that affected disadvantaged localities in under-five mortality (24%), infant mortality rate (19%), acute malnutrition (7%) and DPT vaccination coverage (20%). The main facilitators of the results achieved so far by the PHC strategy were all related to the commitment and good will of actors at different levels. Longterm political commitment, support by local mayors and hospital managers, organized communities historically active in the process of social participation, as well as extramural work carried out by community health workers and health care teams were highly valued. Barriers to the implementation included the structure of the national health system itself, lack of a stable funding source, unsatisfactory working conditions, lack of competencies among health workers regarding family focus and community orientation, and limited involvement of institutions outside the health sector in generating intersectoral responses and promoting community participation. Conclusion: Despite adverse contextual conditions and limitations imposed by the Colombian health system itself, Bogota’s initiative of a PHC strategy has helped to improve the performance of first-level public health care facilities in the essential dimensions of PHC and has also contributed to improvement of child health outcomes and reduction of health inequalities associated with socioeconomic and living conditions. Significant efforts are required to overcome the market approach of the national health system. Structural changes to social policies at the national and district level are needed if the PHC strategy is expected to achieve its full potential. Specific interventions must be designed to have well-trained and motivated human resources, as well as to establish available and stable financial resources for the PHC strategy.

Recent public health scholarship finds that health outcomes are explained by the social and individual determinants of health rather than the individual-level determinants alone. The individualistic perspective has dominated the 20th century institutionalization of public health in the United States where the public health system has tended to focus largely, if not exclusively, on individual factors. This persistent orientation lies in contrast to another set of perspectives that have also persisted, focused on social causes, which are currently dominant in contemporary public health academic literature and in major, international health organizations. Whether the orientation within the United States is due to a prevailing paradigm among public health officials or is the result of new ideas about health causation being dampened under organizational weight is unknown. Despite public health being central to decreasing morbidity and mortality in the 20th century, significant gaps remain in researchers' understanding of what influences practice in the American public health system. My dissertation research investigates the broad outlines of the determinants of health as understood by state public health administrators. I study how the understanding of the determinants of health affects the practice of public health through analyzing how the ideas of state public health administrators interact with the organizational dynamics of the public health organizations they lead. This mixed-methods dissertation uses survey research and in-depth interviews and quantitative and qualitative analysis. I find that state public health officials' professionalization, length of tenure, level of education, and gender affect the perspective of health causation to which they adhere. I also find that the state public health officials with a social health frame more commonly report they are situated in organizations that are learning environments. Both organizational and ideational factors influence public health practice. The interview data expand this finding to paint a complex picture of organizational and ideational factors influencing one another as well as resulting practices. This research reveals that state public health officials often have strong health frames that are only able to shape the edges of their practice due to the political and organizational dynamics interacting with state public health departments. / Ph.
