Thesis (PhD)--Stellenbosch University, 2015. / ENGLISH ABSTRACT: The prevention of mother-to-child transmission (PMTCT) of HIV is a key maternal and child health intervention in the context of the HIV/AIDS pandemic in South Africa. Accordingly, the PMTCT programme has been incorporated in the District Health Management Information System (DHMIS) that collects monthly facility-based data to support the management of public health services. To date, there has not been a comprehensive evaluation of the PMTCT information system. By comparing the experiences in two health districts, using the Performance of Routine Information System Management (PRISM) framework and tools, this study seeks to evaluate the availability, quality and use of process and output indicators for monitoring PMTCT interventions. A comparative analytical and observational study was undertaken using a multi-method approach which included: a self-administered survey of health information personnel to assess confidence and competence levels for routine health information system (RHIS) tasks, an assessment of the routine PMTCT data for quality, completeness, accuracy, and data use; and a facility survey of RHIS processes and resources. In addition, in-depth interviews with 22 key informants and observations in health facilities were conducted. Data were collected from 57 health facilities in a convenience sample of two health districts, and also from 182 health information personnel in the 57 health facilities, three sub-districts, and two district offices. Descriptive statistics, χ2-test, correlation and multiple regression analyses were conducted using STATA® Version 13. A general inductive approach was also used to analyse the qualitative data, which was used for triangulation. The study revealed considerable data quality concerns for the PMTCT information with an average accuracy between the register and routine monthly report of 51% and between the routine monthly reports and DHMIS database of 84% suggesting that the primary point of departure for accurate transfer of data is during the collation process. The importance of human factors was emphasised by the observation that the average confidence level for performing RHIS-related tasks (69%) was not commensurate with the average competence levels (30%). Education was found to be associated with competence, implying that levels of education may be associated with the level at which RHIS competencies are acquired; and that three years or more of post-matriculation education is necessary. Motivation, on the other hand was not associated Stellenbosch University https://scholar.sun.ac.za iv with competence. The study observed the absence of processes such as data-quality checks and data-analysis in place in facilities. There was a general absence of a culture of information use, as a result of lack of trust in the data, and the inability of programme and facility managers to analyse, interpret and use information. We observed differences in the data accuracy by organisational authority, and multivariate analysis and qualitative information suggested that feedback may be an essential process to ensure quality. Although the PRISM framework has been developed from a multi-disciplinary evidence base, this study has been able to validate some of the internal assumptions but has also found some aspects that were not supported such as motivation and data display. Data collected from a larger number of facilities will be required to investigate this further. Institutional capacity to improve RHIS processes, ensure core competencies for RHIS-related tasks are needed, and in the longer term, measures to tackle problems associated with low pass rates in numeracy subjects among high school learners are needed. Further exploration of the possible factors that may influence data accuracy, such as supervision, training and leadership are needed as well as investigating the relationships between human and institutional agency-related aspects, in particular, how individual actions can bring about changes in institutional routines. Further study is needed to determine how decision for planning and evaluating key programmes such as PMTCT are made, and what informs such decisions if not routine data. / AFRIKAANSE OPSOMMING: In die lig van Suid Afrika se MIV/VIGS-pandemie kan ’n ingryping op gesondheidsvlak ’n belangrike rol speel om moeder-na-kind-oordrag (beter bekend as PMTCT) van MIV te voorkom. ’n Inligtingstelsel vir distriksgesondheidsbestuur – die DHMIS – was ontwerp vir die invordering van maandelikse fasiliteitsdata, wat gebruik kan word om die bestuur van openbare gesondheidsdienste en -programme te ondersteun. Die inligtingstelsel self was nog nie omvattend evalueer nie. Hierdie studie het die ervarings van twee gesondheidsdistrikte vergelyk met behulp van die PRISM- (Performance of Routine Information System) raamwerk en -instrumente. Derhalwe het hierdie studie die beskikbaarheid, gehalte en gebruik van proses- en uitsetaanwysers probeer bepaal om die PMTCT-ingrypings te monitor. ’n Vergelykende analitiese en waarnemingstudie is onderneem met behulp van ’n veelvuldige benadering. Die verskillende metodes het ’n selfopname onder gesondheidsinligtingspersoneel ingesluit om hul selfvertroue en bevoegdheid in roetinegesondheidsinligtingstelsel (RHIS)-take te evalueer. Daar was ook ’n assessering van die PMTCT-roetinedata om datagehalte, -volledigheid, -akkuraatheid en -gebruik te beoordeel.’n Fasiliteitsopname oor RHIS-prosesse en –hulpbronne was ook gedoen. Ander navorsingsmetodes het diepte-onderhoude met 22 sleutelpersone ingesluit, sowel as waarnemings in gesondheidsfasiliteite. Data is van 182 gesondheidsinligtingpersoneel van die 57 gesondheidsfasiliteite in ’n geriefsteekproef van twee gesondheidsdistrikte ingesamel. Deskriptiewe statistiek, χ2-toetsing, korrelasie en veelvoudige regressie is met behulp van STATA® weergawe 13 ontleed. ʼn Algemene induktiewe benadering is ook gevolg om die kwalitatiewe data te ontleed. Die studie toon dat menslike faktore ’n impak op datagehalte en -inligting kan hê, met ’n gemiddelde akkuraatheidsyfer van 51% van beide die register en roetine maandelikse verslae. Die akkuraatheid van die maandelikse verslae en RHIS databasis is 84%, wat aandui dat akkuraatheid slegs toegepas word indien inligting uit die staanspoor korrek aangeteken word. Die impak van menslike hulpbronafaktore was beklemtoon toe daar bevind was dat hoewel 69% van RHIS-dataverwerkers vertroue getoon het in die gebruik van RHIS-verwante take, slegs 30% wel bevoeg was om die werk te doen. Opvoeding was grootliks geassosieer met bevoegdheid, wat moontlik voorstel dat sekere vlakke van opvoeding benodig word vir spesifieke RHIS-bevoegdhede. Minsten drie jaar tersiêre opleiding word aanbebeel. Motivering was nie met Stellenbosch University https://scholar.sun.ac.za vi bevoegdheid geklassifeer nie. Die studie het bevind dat daar te min aandag aan datagehalte en –analise gegee word in fasiliteite. Oor die algemeen was daar nie ’n ordentlike kultuur van inligtinggebruik nie, a.g.v. die feit dat daar nie vertroue in die data was nie. Terselftertyd was program- en fasiliteitbestuurders nie bevoeg om inligting te analiseer en ontleed nie. Ons het verskille in die akkuraatheid van data opgetel wat deur organisasie-hoofde gedoen was. Meervoudige analise en kwalitatiewe informasie stel voor dat terugvoering ’n belangrike deel van die proses moet wees om kwaliteit te verseker. Hoewel die PRISM-raamwerk saamgestel was uit ’n multi-dissiplinêre bewyslewering, kon hierdie studie sommige van die interne voorneme valideer, maar daar was aspekte wat nie gestaaf kon word nie. Inligting van ’n groter aantal fasiliteite sal benodig word om verder hierna ondersoek in te stel. Institusionele kapasiteit word benodig om RHIS-prosesses te verbeter en basiese vaardighede vir RHIS-verwante take te verseker. Op langtermynvlak moet daar ook gekyk word na probleme wat lei tot laë slaagsyfers in syfervaardighede in hoërskoolleerders. Verdere ondersoek moet ingestel word om vas te stel watter faktore moontlik akkurate data teweeg kan bring. Dit sluit toesig, opleiding en leierskap, asook die verhoudings tussen menslike en agentskap-verwante aspekte in. Die feit dat optrede op individuele vlak veranderings in institusionele roetines kan aanbring, moet spesifiek na gekyk word. Verdere studies kan help om vas te stel hoe besluite vir beplanning en evaluaring vir hoofprogramme soos PMTCT gemaak word – asook hoe die besluite gemaak word indien hulle nie roetine voorafgaan nie.

This study aimed at assessing factors related to male participation in PMTCT in three public hospitals in Addis Ababa, Ethiopia. A quantitative, descriptive correlational design was used to assess correlation between male participation and socio-demographics, knowledge and awareness in HIV/PMTCT, socio-cultural belief, programmatic factors and reported risk. Male partners (n=216) were interviewed and reviews of HIV counselling and testing (HCT) acceptance formats were made. The major findings were 54.5% (n=156) males reported receiving HCT during their visit to partner’s antenatal care. Some 71.5 % (n=677) of women were accompanied to labour wards by male partners; 86.5% (n=208) of males accepted intra-partum HCT; 55.1% (n=216) scored above the mean score (10) on a 15-point scale for male participation. Male participation in PMTCT was found to have a statistically significant but weak correlation with educational level (r=0.193), income (r=0.167), PMTCT knowledge and awareness (r=0.172), socio-cultural belief (r=-0.164) and reported risk (r=-0.23). / Health Studies / M.A. (Public Health)

La perte au suivi diminue grandement l’efficacité des interventions de prévention de la transmission mère-enfant du VIH en Afrique subsaharienne. Devrait-on donc choisir des traitements courts ou longs de pTME? Nous avons mené une revue systématique des études sur l’efficacité de traitements avec et sans composante anténatale et évalué l’impact de la perte au suivi sur leur efficacité. Nous avons trouvé qu’après ajustement pour la perte au suivi, les traitements avec composante anténatale ont encore une efficacité plus élevée à prévenir la TME. Les intervenants ne devraient pas craindre l’utilisation de traitements plus longs auprès de populations à risque de perte au suivi. Plus d’études sont nécessaires pour déterminer comment les interventions peuvent être adaptées au virage dans la pTME. / Loss to follow-up greatly decreases efficiency of MTCT interventions in sub-Saharan Africa. Should we therefore choose shorter pMTCT treatments over longer ones? We conducted a systematic review of studies on the efficiency of pMTCT treatments with or without an antenatal component. We found that after adjustment, treatments with an antenatal component still had a higher efficiency at decreasing MTCT despite loss to follow-up. Healthcare providers shouldn’t fear using longer treatments amongst populations at high risk of loss to follow-up. More studies are needed to determine how current interventions can be better adapted to the turnaround in pMTCT interventions.

Problématique : Implanté en 2004 au Bénin, le programme national de prévention de la transmission du VIH de la mère à l’enfant (PTME) semble globalement bien implanté. Toutefois une enquête, en 2005, révèle certaines difficultés, particulièrement au niveau de la couverture du programme: seulement 70 à 75 % des femmes enceintes vues en consultations prénatales ont été dépistées et 33 % des 1150 femmes dépistées séropositives ont accouché suivant le protocole de PTME. En outre, d’un site à un autre, on relève une grande variation dans la couverture en termes de dépistage et de suivi des femmes enceintes infectées. Cette faiblesse dans la couverture nous a amené à questionner le contexte organisationnel dans lequel le programme est implanté. Objectif : L’objectif général de cette thèse est d’analyser l'implantation de la PTME au Bénin. Le premier objectif spécifique consiste à identifier et comprendre les enjeux reliés à la façon de rejoindre les femmes enceintes dans le cadre du dépistage. Le second consiste à comprendre le contexte d’implantation et son influence sur la mise en œuvre de la PTME. Méthodologie : Cette recherche évaluative s’appuie sur une étude de cas. Six maternités ont été sélectionnées avec le souhait de représenter les différents contextes d’organisation des services. Les données ont été collectées par observation non participante, entrevues semi-dirigées (n=41) réalisées avec des prestataires de services, analyse documentaire des rapports d’activités des maternités et par questionnaires administrés aux femmes enceintes en consultations prénatales (n=371). Résultats : Le premier article a permis d'apprécier le caractère libre et éclairé du consentement au dépistage. Une majorité des femmes enceintes, suivies dans les centres privés, ont été dépistées sans être effectivement informées de la PTME alors que les femmes fréquentant les autres maternités connaissent mieux les composantes de la PTME. Le caractère volontaire du consentement des femmes est généralement respecté sur tous les sites. Le deuxième article porte sur l'analyse de la qualité du conseil pré-test. Seulement 54% des femmes enceintes ont participé à un conseil en groupe et 80% à un conseil individuel. Dans les centres où sont dispensées des séances d'information de groupe, la qualité est meilleure que dans les centres qui dispensent un conseil individuel exclusif. Le troisième article analyse l'influence du contexte d'implantation sur la mise en œuvre du programme. Parmi les facteurs qui contribuent favorablement à la mise en œuvre on relève la proximité d’un centre de référence et la coordination des activités de PTME dans une zone géographique, la responsabilisation du prestataire dédié à la PTME, la supervision formative régulière accompagnée de séances de discussion collective et l’implication des médiatrices dans la recherche active des perdues de vues. A l’opposé, la responsabilisation des médiatrices pour la réalisation du conseil individuel et du dépistage ne favorise pas une bonne mise en œuvre de la PTME. Conclusion : Nos résultats montrent qu'il est possible de jouer sur l'organisation des services de santé dans le cadre du programme du PTME pour améliorer la façon dont le programme est implanté tant dans les centres privés que publics, sans que cela ne représente un ajout net de ressources. C'est le cas de l’amélioration de la qualité du conseil et du dépistage, de l’implantation du processus interne d’apprentissage organisationnel et de la coordination des services. / Problem: Launched in 2004 in Benin, the national program for prevention of mother-to-child transmission (PMCTC) of HIV appears to have been well implemented. Nevertheless, a 2005 survey revealed certain problems, particularly with respect to the program’s coverage: only 70% to 75% of pregnant women seen in prenatal consultation were screened, and only 33% of the 1,150 women found to be HIV-infected were delivered according to the PMCTC protocol. In addition, there was great variation in coverage from one site to another in terms of screening and of follow-up for infected pregnant women. This inadequate coverage raised questions about the organizational context in which the program is implemented. Objectives: The overall objective of this thesis is to analyze the implementation of the PMTCT program in Benin. The first specific objective is to identify and understand the issues related to how pregnant women are contacted as part of the screening process. The second is to understand the implementation context and its influence on how the PMTCT program is carried out. Methodology: This evaluative research is based on a case study. Six maternity units were selected in order to provide a representative sample of the different service organization settings. Data were collected through non-participant observation, semi-structured interviews (n=41) with service providers, documentary analysis of the maternity centres’ activity reports, and questionnaires administered to pregnant women at prenatal consultations (n=371). Results: The first article, whose objective was to appreciate the free and informed nature of consent to screening, revealed differences between maternity. A majority of pregnant women followed in private centres were screened without being adequately informed about the PMTCT program, whereas the women in others centres were better informed about the specifics of the program. The voluntary nature of the consent was generally respected. The second article analyzes the quality of the pre-test counselling. Only 54% of the pregnant women in our sample participated in group pre-test counselling sessions and 80% in individual counselling. In centres, which organize group information sessions, the quality is better than in centres, where counselling is provided exclusively to individuals. The third article analyzes the influence of the implementation context on how the program is carried out. Among the factors that contribute positively to implementation are: the proximity of a referral centre and the coordination of PMTCT activities within a geographic area; designating a care provider to oversee the PMTCT program; conducting regular formative supervision with group discussion sessions; and involving mediators—HIV-positive women hired by the program to provide psychological accompaniment—in actively seeking out women who have been lost to follow-up. Conversely, putting mediators in charge of individual counselling or of screening does not foster good implementation of the PMTCT program. Conclusion: Our results show that it is possible to adjust the organization of healthcare services for the PMTCT program in order to improve implementation in both the private and public sectors with no net increase in resources. This is the case for improving the quality of counselling and of screening, the implementation of the internal process of organizational learning, and the coordination of services.

First eleven leaves not numbered / The purpose of this study was to identify, explore and describe the potential contributing factors of the upsurge of HIV among children aged three to eighteen months in the Mangaung Metropolitan area of the Free State Province in South Africa. The study was conducted at five primary healthcare facilities and one hospital in the Mangaung metropolitan municipality of the Free State Province with sixty randomly selected mothers of children testing HIV-positive for the first time between the ages of three and eighteen months. The convergent mixed-methods research design was opted for, according to which both qualitative and quantitative data were collected at the same health facilities selected by means of cluster sampling. The review of medical records, unstructured interviews, and structured questionnaires were used for qualitative and quantitative data collection, while random cluster sampling was used for participant selection. Thematic data analysis was applied for the interpretation of recurrent patterns of qualitative and quantitative data. The study results revealed that mothers were well-informed about the prevention of mother-to-child-transmission. The main factors that contributed to more children testing HIV positive after the routine tests were conducted at ten weeks included non-adherence factors to PMTCT prescripts mainly by mothers, such as: babies were not brought to the clinics for testing and immunisations at ten weeks, and that mothers acquired HIV infection during the breastfeeding period. Some other potential contributing factors were late antenatal booking which lead to the delay in initiation of antiretroviral treatment, nonadherence to antiretroviral therapy during pregnancy, and mixed feeding. The themes that emerged from the qualitative data were psychological factors, emotional factors, socioeconomic factors, missed opportunities, risky behaviour, as well as women disempowerment; while some mothers were left with unanswered questions. The results of the qualitative part complemented the quantitative findings as they uncovered the factors that led to the deviation from the PMTCT prescripts by the mothers. The study’s recommendations include PMTCT psychological assessment and counselling; partner and community involvement; women empowerment; and that couple testing at antenatal and postnatal clinics should be a national policy subjected to protracted monitoring and evaluation processes. / Health Studies / D.

The prevention of mother-to-child transmission is one of the most powerful tools in human immunodeficiency virus type 1 (HIV-1) prevention and has huge potential to improve both maternal and child health. In the absence of any preventative measures, infants born to and breastfed by their HIV-positive mothers have roughly a one-in-three chance of acquiring the infection themselves. HIV can be passed on from mother-to-child during pregnancy, during labor and delivery, and even after during breastfeeding. Intrapartum and neonatal single-dose nevirapine (sd-NVP) is the foundation of preventing mother-to-child transmission in lower resource settings where it has been used alone or as part of combination regimens. Both its simplicity and its long plasma half-life contribute to the success of sd-NVP based therapy. However, sd-NVP frequently results in HIV-1 viral resistance in mothers and children who become HIV infected despite prophylaxis. Sd-NVP leads to the development of non-nucleoside reverse transcriptase inhibitors (NNRTI) drug resistance, compromising the success of treatment of mother and child with subsequent antiretroviral combinations. Resistance to NNRTIs is particularly worrisome in lower resource settings since many subsequent regimens for maternal and infant antiretroviral therapy include a NNRTI drug.

Thesis (MNutr (Interdisciplinary Health Sciences. Human Nutrition))--Stellenbosch University, 2008. / Objective: Primary: To investigate the effect of pasteurisation on the composition of expressed breast milk from HIV positive mothers and its adequacy in relation to the growth of their VLBW premature infants. Methods: A descriptive, prospective case-controlled pilot study was performed in 3 regional state hospitals in the Western Cape, South Africa. The control and study groups consisted of 12 HIV negative and 11 HIV positive mothers, with their VLBW premature infants, respectively. All mothers (19 - 35 years old) belonged to the Xhosa ethnic group. All infants were born <34 weeks gestation and birth weight <1500g. Eight breast milk samples were collected on days 6, 7, 13, 14, 20, 21, 27 and 28 from all mothers during the first 28 days after birth. Breast milk was expressed by hand or pump from either the right or left breast. Half of each breast milk sample was kept raw. The remaining sample was Pretoria pasteurised, after which both samples were subdivided into 3 or 4 aliquots to determine energy, protein, carbohydrate, fat, folate, calcium, phosphorus, magnesium, sodium, otassium, iron, copper, zinc content and HI viral load (study group only). The mothers’ dietary intake during pregnancy and lactation was obtained by means of a quantitative food frequency questionnaire and repeated 24-hour recall respectively. The infants’ dietary intake was recorded daily. Mothers’ anthropometric measurements taken at study entry and exit were weight, height and mid-upper arm circumference. All infants’ daily weight, as well as length and head circumference at birth and on day 28 postpartum was obtained. Biochemical analysis was performed on the blood samples obtained at study entry and exit from all mothers and infants. For statistical analysis, Statistica® (release no 7, 2006) was used for repeated measures analysis of variance (ANOVA) to determine the effect of HIV, pasteurisation, milk expression and time on the composition of the breast milk. Results: There was no significant difference in the studied macro- and micronutrient composition between raw or pasteurised expressed breast milk from HIV positive and HIV negative mothers with premature infants. A significant decline in breast milk protein (p<0.01), magnesium (p=0.045), potassium (p=0.002), zinc (p<0.01) and copper (p=0.03) content was observed for the whole study population over time, while folic acid content increased significantly (p=0.012) over time. The sodium/potassium ratio of both groups remained strongly indicative of the presence of sub-clinical mastitis. A significant (p=0.03) greater mean volume of milk was obtained with pump [42.5 Standard Deviation (SD) 18.1 ml], compared to hand expression [36.7 (16.7) ml]. Method of expression did not result in a significant difference in breast milk composition for any of the nutrients studied. Eight (35%) infants were born SGA while 21 (91%) infants were SGA on day 28. The infants gained a mean of 16.37 (4.5) g/kg/day (i.e. 91% of the recommended growth rate of >18g/kg/day) from the day on which birth weight was regained. The control and study group infants respectively consumed a mean of 3.27 (1.36) and 3.21 (1.36) g protein/kg/day and 138.1 (33.8) and 142.3 (33.8) kcal total energy/kg/day. This corresponds to a PER of 2.6 (control group) and 2.5 (study group) respectively, which cannot provide for the increased growth needs of the SGA infant in need of catch-up growth. Six infants experienced an incident of Grade 1 NEC which resolved and all completed the study. Two (18%) HIV-exposed infants were found to be HIV positive at 28 days post delivery. Four participating infants died. No adverse event or mortality was related to the study protocol as no intervention was undertaken. Conclusion: HIV positive Xhosa mothers provide as nutritious breast milk to their VLBW premature infants as HIV negative Xhosa mothers. Maternal nutrient intake during pregnancy and lactation did not have a significant effect on the nutritional composition of breast milk, except for folate content.

Study Objective The objectives of this study are: (1) to explore the impact of the national consolidated guidelines for Option B+ PMTCT on the work of healthcare professionals at both clinical and management levels (including nurses, physicians and management) (2) to understand pregnant HIV-positive women views and experiences with ART for life, as a way to better manage the Option B+ PMTCT programme within state hospitals Research Questions The following research questions will be used to explore both perceptions of healthcare professionals and patients: 1.How have the national consolidated guidelines for Option B+ PMTCT affected the work of healthcare professionals? 2.What are pregnant HIV-positive women’s views and experiences about going on lifetime treatment with ARVs? / ABSTRACT Background. South Africa’s National Department of Health has adopted World Health Organization’s (WHO) 2013 consolidated guidelines on the use of ARVs for treatment and prevention of HIV infection. The guidelines include changes for prevention of mother to child transmission (PMTCT) through Option B+. Option B+ aims to reduce the HIV prevalence rate amongst these women by placing them on ART for life, no matter their CD4 count. As a result, in January 2015, these guidelines were implemented for the PMTCT programme at RMMCH. Little is known about the impact of these new guidelines on the work of healthcare professionals in state hospitals. Most importantly, no research has focused on how these changes have affected adherence for the patients. Purpose. The purpose of this research project is (1) to explore the impact of the Option B+ PMTCT programme on the work of healthcare professionals, and (2) to understand pregnant HIV-positive women views and experiences with ART for life, as a way to better manage the Option B+ PMTCT programme. Methods. A qualitative study design is used with a phenomenological approach. The methodology uses demographic questionnaires and semi-structured interviews with healthcare professionals and patients. The study is situated in Johannesburg, South Africa. Findings. The findings demonstrate that work has changed and become difficult to manage for all healthcare professionals because of (1) the need for strengthening indicators for tracking to decrease loss to follow-up (LTFU); (2) inconsistency in delivery of counseling and support services and the need for communication across clinical departments; and (3) the lack of compassion and understanding by service providers. The difficult healthcare environment has affected overall views and experiences of pregnant HIV-positive women going on ART for life. All 55 patient participants responded that they chose to take the fixed-dose combination (FDC) for life to protect the health of the baby and felt ART for life can be stopped after giving birth. Conclusion. Implications for future research include the need to address changes within the healthcare system at both clinical and management levels. It is crucial to incorporate the perspective of patients in policy implementation; uptake and adherence are key indicators in informing whether the Option B+ PMTCT programme is being adapted into state hospitals effectively. There needs to be extensive research on how to strengthen indicators for long term scalability and sustainability of the programme. Future evaluations need to address, will interdisciplinary collaboration within hospitals improve the management and understanding of Option B+? / Thesis / Master of Science (MSc)
