Factors influencing the implementation of health promoting schools : a multiple case study of three secondary schools in a resource limited community in Cape Town

Mohamed, Suraya January 2016 (has links)
Philosophiae Doctor - PhD / Introduction: This study was conducted because of a gap in information on the factors influencing the health promoting schools (HPS) implementation process in South Africa (SA) specifically and in secondary schools globally. The aim of this context- sensitive, practice-based study was to explore and understand the complexity of the factors that influenced the implementation process of HPS in three secondary schools in a resource-limited setting in Cape Town, SA. This research drew on a five year project that initiated the implementation of HPS in these schools. Methodology: An exploratory qualitative study was used, adopting a multiple case study design. The sample included two principals, ten teachers and 30 students involved in HPS implementation at their schools, and the three school facilitators, who served as mentors to the schools. The data collection methods included: individual interviews, focus group discussions, documentary review, secondary data and observations. A conceptual framework was developed drawing on the settings approach and various implementation frameworks and was used to analyse the findings. Thematic analysis was employed and the data for each case were analysed separately first before undertaking cross case analysis. Findings: A combination of several internal and external factors influenced the ability of the schools to implement and integrate HPS as a whole school approach. A key factor was the degree of understanding of the HPS concept by all key actors and where there was lucid understanding, there was better integration. Significant school factors included the schools’ readiness for change; a culture of collaboration and cooperation; existing school structures, practices and workload; the leadership style and management role of the principals; the role and influence of HPS champion teachers; and the role that students played. The major external factors included the role of the education district; the role of project team as external catalysts for change; and the community context. The main achievements in all schools were discrete activities, including co-curricular activities rather than changes to routine school functions. This highlighted the difficulty in implementing HPS as a whole school approach, a challenge typical of all health promoting settings. Conclusion: The findings illustrate the challenge of achieving full integration of HPS, although the influencing factors, and hence level of integration varied mainly according to context. This highlights the complexity of the different factors and their impact. The study demonstrates the paradox of HPS implementation. In that, despite the recognition of the value of HPS, the challenges to address the complexity of factors that would have brought about change through a whole school approach were too great. It was too difficult to change the status quo from what was routinely done to a more radical way of working due to the conservatism of traditional ways of working and extent of adjustment that it would have resulted. It was therefore only possible to put simple, discrete, strategies in place and that was not too resource intensive. The study concluded that this does not imply that HPS should not be attempted, particularly where there are adverse conditions that would benefit from HPS. Starting with marginal changes, it can be effective in increasing the schools’ readiness for change, building on the achievements both in activities and structures, and the resultant commitment by those involved. Once they experience these changes it will more likely enable schools to incrementally attempt more complex changes. The key recommendations for within the school include: building the understanding and capacity of relevant actors to actively support the implementation of HPS; building the capacity of the principal to create an environment which is conducive to change; and providing support for the HPS champions and students. Recommendations for those external to the school include: support from external catalysts who can provide expertise and mentorship; support from the education district, especially in terms of policies on integration, resources, and raising the profile of HPS; and better collaboration between the education and health sectors. Although most of the literature on HPS implementation identifies similar issues to those found in this study, the complexity has not, to date, been sufficiently described. The contribution of this study, therefore, is to take the debate on the complexity of the factors influencing HPS implementation forward.

Survey on nail discoloration and association with CD4 count among untreated HIV patients at Apin Centre, Nigeria

Ekeh, Peter Nnamdi January 2010 (has links)
<p>Eligibility for antiretroviral therapy (ART) in HIV-infected patients is defined either by a cluster of differentiation antigen 4 (CD4) count of less than 200cells/mm3 or clinical diagnosis of WHO stage III and IV. Therefore, the decision to start ART becomes difficult when CD4 cell count is not available. With limited laboratory infrastructure, the decision to start ART is usually made based on clinical symptoms leading to late commencement of ART. This calls for alternative criteria to see if nail discoloration (ND) correlates with low CD4 count among untreated HIV infected patients. This will serve as a complementary screening tool for identifying asymptomatic ARV naive HIV patients with a CD4 cell count of less than 200cells/mm3 which signifies&nbsp / severe immunosuppression. Study Design and Setting: This was a quantitative cross-sectional descriptive and analytical study involving adult ART na&iuml / ve HIV infected patients in WHO stage I and II. Systematic sampling was used to select the participants from all adult ART na&iuml / ve HIV infected patients attending APIN clinic, located at the Jos University Teaching Hospital (JUTH), Jos, Nigeria. Data Collection: Face-to-face interviews, physical examination and relevant laboratory investigations with selected participants were conducted using a questionnaire guide. Questions on socio-demographic characteristics, clinical data, general physical examinations including finger nail examination and photographing with subsequent laboratory investigations including CD4 count and western blot were employed. Data Analysis: Variables were categorized and data analyzed using descriptive statistics including the frequency, percentage frequency / mean and standard deviation of continuous variables. Association between CD4 count of &le / 200cells/mm3 and ND was tested using the chisquare test with an alpha level of 0.05. Prevalence of ND, sensitivity, specificity, positive predictive and negative predictive values and accuracy of the screening test of ND was calculated. Results: 394 patients had their fingernails photographed and assessed. It was shown that distal banded and grey nails were the common types of ND seen with a prevalence of 38%. There was an association between CD4 count &le / 200cells/mm3 and ND (p&lt / 0.0001). CD4 count &le / 200cells/mm3 was a risk factor for developing ND (RR=2.3[1.8-3.6]). The association has a sensitivity of 78%, specificity of 55%, positive predictive value of 50%, and negative predictive value of 80% and accuracy of test 63%. Conclusion: With a significant association (p&lt / 0.0001) and a sensitivity of 78%, ND can be a useful clinical indicator of immune dysfunction mediated by HIV among patients in WHO stage I or II. ND can either be a clinical sign or a symptom in HIV patients with a CD4 of &le / 200cells/mm3 as seen in the study as the specificity and sensitivity of ND compared favourably with other WHO stage III diagnosis. Recommendations: Nail discoloration should complement CD4 count as an additional staging sign to help identify patients likely to benefit from ART especially in resource-limited settings. Finally, all patients with grey or distal banded should be on co-trimoxaxole prophylaxis in line with WHO /national guideline on the use of co-trimoxaxole for all HIV positive patients with a CD4 cell count of &le / 350cells/mm3.</p>

Prescribing cotrimoxazole prophylactic therapy (CPT) before and after an electronic medical record system implementation in two selected hospitals in Malawi

Gadabu, Oliver Jintha 11 1900 (has links)
Opportunistic infections (OIs) have been identified as a leading cause of poor outcomes in the ARV therapy (ART) programme. In order to reduce OIs, the Malawi, MoH introduced routine prescription of cotrimoxazole preventive therapy (CPT) in 2005. The MoH also started scaling up a point-of-care electronic medical record (EMR) system in 2007 to improve monitoring and evaluation. This study had the following objectives: i) to quantify prescription of CPT before and after implementing EMR; ii) to compare the difference in CPT prescription before and after implementing EMR. A historically controlled study design was used to compare CPT prescriptions one year before, and one year after implementation of the EMR at two health facilities. The data indicated that there was a significant (P <0.001) decrease in CPT prescribing at one health facility and a significant increase in CPT prescription at another. / Health Studies / M.A. (Public Health)

Determinants contributing to exclusive breastfeeding in HIV-infected mothers of infants aged 0-6 months who attend an NGO Health Centre in Elandsdoorn Village

Mohlajoa, Katlego Thabo 02 1900 (has links)
Text in English / Breastfeeding is particularly important in resource-poor regions of the world, where limited access to clean water increases the risk of diarrhoeal disease if replacement feeding is used. However, human immunodeficiency virus type 1 (HIV-1) is transmitted through human milk. Purpose of the study The purpose of this study was to describe the determinants contributing to exclusive breastfeeding in HIV-infected mothers of infants aged 0 to 6 months who attend an NGO Health Centre in Elandsdoorn Village. Methods A quantitative research approach using a non-experimental cross-sectional study was undertaken to conduct this study. A self-reported study questionnaire was used to collect data from study participants. Purposive sampling was used to sample 75 mothers from 18 to 45 years of age who were HIV-positive. SPSS version 23 was used to analyse the data. Results The study results indicated that there are determinants contributing to exclusive breastfeeding and a need to establish a more comprehensive approach to educating pregnant women on reproductive health issues, and exclusive breastfeeding in particular. Factors contributing to low levels of exclusive breastfeeding included breast problems, societal influence, maternal health concerns, insufficient support, fear of stigmatisation, and babies’ health concerns. This caused mothers to discontinue exclusive breastfeeding. Conclusions The intention of this study was to reveal the determinants of exclusive breastfeeding affecting mothers who are HIV-infected and breastfeeding their infants. / Health Studies / M.P.H.
