The effectiveness of PMTCT programmes through the measurement of NVP coverage in populations of women delivering in designated areas in the Western Cape Region of South Africa
Includes bibliographical references.[Objective] The objective was to assess the uptake and coverage of SD-NVP to prevent mother-to-child transmission of HIV in women of unknown HIV status presenting in labour a sample of delivery sites in the Western Cape. This monitoring activity also accurately measures the prevalence of HIV among pregnant women and ascertains the proportion of HIV exposed infants delivered to these mothers, who received NVP prophylaxis to prevent MTCT. [ Design ] Anonymous, unlinked specimens of cord blood from discarded placentas were tested for HIV antibodies to determine population-level information on HIV infection and NVP coverage among all women delivering in the facilities. Uptake was measured by counting the number of women who were recorded to have accepted NVP when offered while coverage was measured by using the cord blood NVP assay. [ Results ] A total of 2198 (96.5%) cord blood specimens were collected from women at delivery. From these, 1876 (85.4%) women received pre-test counselling. Of those who were counselled, 1851 (84.2%) were tested for HIV and 365 (19.3%) tested positive. Amongst those who were infected, 229 (62.7%) received SD-NVP and but only 57.8% adhered to SD-NVP according to the cord blood. Of the infants born to HIV-infected mothers, 311 (85.2%) were recorded as 9 having received SD-NVP. There was no significant difference in SD-NVP uptake between the two facilities. The overall NVP coverage (mother and infant doses) was 55.3%. [ Conclusions ] The NVP coverage of 55.3% is poor. In order for PMTCT services to be successful, each mother-infant pair should go through a rigorous cascade of events that include HIV testing, receipt of results, diagnosis and drug adherence. The attrition cascade in this study was described using a new cord blood surveillance methodology. Coverage fails for a number of reasons and interventions are likely to differ from one facility to another. Appropriate interventions should be introduced to reduce the transmission to infants
Expressions of actor power in implementation: A qualitative case study of a health service intervention in South Africa
Implementation frameworks and theories acknowledge the role of power as a factor in the adoption (or
not) of interventions in health services. Despite this recognition, there is a paucity of evidence on how
interventions at the front line of health systems confront or shape existing power relations. This paper
reports on a study of actor power in the implementation of an intervention to improve maternal, neonatal
and child health care quality and outcomes in a rural district of South Africa.A retrospective qualitative case study based on interviews with 34 actors in three âimplementation unitsâ â
a district hospital and surrounding primary health care services â of the district, selected as purposefully
representing full, moderate and low implementation of the intervention some three years after it was first
introduced. Data are analysed using Veneklasen and Millerâs typology of the forms of power â namely
âpower overâ, âpower toâ, âpower withinâ and âpower withâ
Social and structural determinants of household support for ART adherence in low- and middle-income countries: A systematic review
Adherence to HIV antiretroviral therapy (ART) is a crucial factor in health outcomes for people living with HIV (PLWH). Interventions to support ART adherence are increasingly focused on the household as a source of social support. This review aims to examine the social and structural determinants of support for ART adherence within households and families in low- and middleincome countries (LMICs). The review methodology followed the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. Seven databases were searched for peer-reviewed literature. The terms searched thematically covered (1) ART adherence, (2) household and family and (3) support and care. Thirty-three studies conducted in 15 LMICs were selected and a mixed methods synthesis was undertaken. Social and structural determinants affected the type, quality and amount of support for PLWH of all ages, which affected PLWHâs ART adherence. Gender norms affected the type of support that household members give to PLWH. Education moderated household support for ART adherence through literacy and language skills
Whole-system change: case study of factors facilitating early implementation of a primary health care reform in a South African province
BACKGROUND: Whole-system interventions are those that entail system wide changes in goals, service delivery arrangements and relationships between actors, requiring approaches to implementation that go beyond projects or programmes. METHODS: Drawing on concepts from complexity theory, this paper describes the catalysts to implementation of a whole-system intervention in the North West Province of South Africa. This province was an early adopter of a national primary health care (PHC) strategy that included the establishment of PHC outreach teams based on
generalist community health workers. We interviewed a cross section of provincial actors, from senior to frontline, observed processes and reviewed secondary data, to construct a descriptive-explanatory case study of early implementation of the PHC outreach team strategy and the factors facilitating this in the province. RESULTS: Implementation of the PHC outreach team strategy was characterised by the following features: 1) A favourable provincial context of a well established district and sub-district health system and long standing values in support of PHC; 2) The forging of a collective vision for the new strategy that built on prior history and values and that led to distributed leadership and ownership of the new policy; 3) An implementation strategy that ensured alignment of systems (information, human resources) and appropriate sequencing of activities (planning, training, piloting, household campaigns); 4) The privileging of âcommunity dialoguesâ and local manager participation in the early
phases; 5) The establishment of special implementation structures: a PHC Task Team (chaired by a senior provincial manager) to enable feedback and ensure accountability, and an NGO partnership that provided flexible support for implementation.
CONCLUSIONS: These features resonate with the deliberative, multi-level and context sensitive approaches described as the âsimple rulesâ of successful PHC system change in other settings. Although implementation was not without tensions and weaknesses, particularly at the front-line of the PHC system, the case study highlights how a collective vision can facilitate commitment to and engagement with new policy in complex organisational environments. Successful adoption does not, however, guarantee sustained implementation at scale, and we consider the challenges to further information.Web of Scienc
Measurement approaches in continuum of care for maternal health: a critical interpretive synthesis of evidence from LMICs and its implications for the South African context
Background: Global strategies recommend a continuum of care for maternal health to improve outcomes and
access to care in low and middle income countries (LMICs). South Africa has already set priority interventions along
the continuum of care for maternal health, and mandated their implementation at the district health level.
However, the approach for monitoring access to this continuum of care has not yet been defined. This review
assessed measurement approaches in continuum of care for maternal health among LMICs and their implications
for the South African context.
Methods: We conducted a critical interpretive synthesis of quantitative and qualitative research sourced from Academic
Search Complete (EBSCO), MEDLINE (Pubmed), Cambridge Journals Online, Credo Reference and Science Direct. We
selected 20 out of 118 articles into the analysis, following a rigorous quality appraisal and relevance assessment. The
outcomes of the synthesis were new constructs for the measurement of continuum of care for maternal health, derived
from the existing knowledge gaps.
Results: We learned that coverage was the main approach for measuring and monitoring the continuum of care for
maternal health in LMICs. The measure of effective coverage was also used to integrate quality into coverage of care. Like
coverage, there was no uniform definition of effective coverage, and we observed gaps in the measurement of multiple
dimensions of quality. From the evidence, we derived a new construct called adequacy that incorporated timeliness of
care, coverage, and the complex nature of quality. We described the implications of adequacy to the measurement of
the continuum of care for maternal health in South Africa.
Conclusions: Critical interpretive synthesis allowed new understandings of measurement of the continuum of care for
maternal health in South Africa. The new construct of adequacy can be the basis of a new measure of access to the
continuum of care for maternal health. Although adequacy conceptualizes a more holistic approach, more research is
needed to derive its indicators and metrics using South African data sources
The co-occurrence of the SAVA syndemic, depression and anxiety as barriers to antiretroviral therapy adherence among Sub-Saharan Africa population groups: A scoping review protocol
The scale-up of access to antiretroviral therapy has transformed HIV from an acute, terminal
disease to a manageable chronic illness. Yet, sustaining high levels of antiretroviral therapy
adherence remain a challenge, especially in the sub-Saharan Africa region which is disproportionately
affected by HIV. This protocol proposes a scoping review to explore literature
reporting on the antiretroviral therapy adherence levels among people who experience substance
abuse and violence (SAVA) syndemics, as well as mood disorders such as anxiety
and depression among people living with HIV in sub-Saharan Africa
Improving the validity, relevance and feasibility of the continuum of care framework for maternal health in South Africa: a thematic analysis of expertsâ perspectives
Background: The continuum of care is a key strategy for ensuring comprehensive service delivery for maternal
health, while acknowledging the role of the social determinants of health. However, there is little research on the
operationalisation of the framework by decision-makers and implementers to address maternal health challenges.
The framework should be measurable and feasible for implementation in low- and middle-income country
contexts. In this study, we explore expertsâ perspective on monitoring indicators for continuum of care and key
issues related to their use in the South African context.
Methods: We conducted key informant interviews with a range of experts in decision-making and programme
implementation roles in the health system and relevant sectors. Key informants provided their perspectives on
systematically selected, nationally representative monitoring indicators in terms of validity, relevance and feasibility.
We interviewed 13 key informants and conducted a thematic analysis of their responses using multi-stage coding
techniques in Atlas.ti 8.4.
Results: Experts believed that the continuum of care framework and monitoring indicators offer a multisectoral
perspective for maternal health intervention missing in current programmes. To improve validity of monitoring
indicators, experts suggested reflection on the use of proxy indicators and improvement of data to allow for equity
analysis. In terms of relevance and feasibility, experts believe there was potential to foster co-accountability using
continuum of care indicators. However, as experts stated, new indicators should be integrated that directly measure
intersectoral collaboration for maternal health. In addition, experts recommended that the framework and indicators
should evolve over time to reflect evolving policy priorities and public health challenges.
Conclusion: Experts, as decision-makers and implementers, helped identify key issues in the application of the
continuum of care framework and its indicators. The use of local indicators can bring the continuum of care
framework from an under-utilised strategy to a useful tool for action and decision-making in maternal health. Our
findings point to measurement issues and systematic changes needed to improve comprehensive monitoring of
maternal health interventions in South Africa. Our methods can be applied to other low- and middle-income
countries using the continuum of care framework and locally available indicators
Review of health and non-health sector indicators for monitoring service provision along the continuum of care for maternal health
This study uses health and non-health sector data sources to select and assess available indicators for
service provision along the continuum of care for maternal health at subnational levels in South Africa. It applies the
adequacy approach established in another study to assess the multi-dimensionality of available indicators. Using
adequacy and the process of assessment in the study, the comprehensiveness of the continuum of care for improving
maternal health outcomes can be assessed.We found 27 indicators of care utilization and access, linkages of care, and quality of care from the routine
district health information system. The General Household Survey contained 11 indicators for the social determinants
of health on the continuum of care framework. Indicator gaps include health promotion during and after pregnancy,
maternal nutrition, empowerment and quality of care. At present, the available indicators measure about 74% of the
interventions on the continuum of care framework. We make recommendations regarding improvements needed
to better measure and monitor the continuum of care for maternal health. These involve actions within the health
system and include integration of non-health system indicators
Unequal gender norms are related to Symptoms of Depression Among Young Adolescents: A Cross-Sectional, Cross-Cultural Study
Purpose: This study was undertaken among 10- to 14-year-old girls and boys in disadvantaged areas of Shanghai, China; Cuenca, Ecuador; Flanders, Belgium; and Denpasar and Semarang, Indonesia. It aimed to assess whether gender norms are related to depressive symptomatology, and to examine whether sex differences in depressive symptoms can be explained by differences in gender norm perceptions. Methods: We examined the distributions of depressive symptoms and two gender norms scales, gender stereotypical traits (GST), and sexual double standard (SDS), across sites and by sex. We next assessed crude and adjusted associations between each of the gender norms scales and depressive symptoms. Finally, we conducted path analysis to examine the mediating role of gender perceptions in sex differences in depressive symptoms. Results: Girls reported more depressive symptoms than boys in all sites except Denpasar. SDS perceptions were more unequal among girls in most sites, while GST perceptions were more unequal among boys in all sites except Semarang. Gender-equal SDS and GST perceptions were associated with fewer depressive symptoms, while unequal perceptions were related to more symptoms. Gendered perceptions about traits and relationships appeared to partially mediate relationships between sex and depressive symptoms in Shanghai, Cuenca, and Semarang. Conclusions: Unequal gender norm perceptions were linked to poor mental health among boys and girls, suggesting that gender norms may play a role in psychological wellbeing for adolescents of both sexes. Gender norm perceptions appear to play a role in mental health sex disparities we observed across site
A Cost-Effectiveness Analysis of a Home- Based HIV Counselling and Testing Intervention versus the Standard (Facility Based) HIV Testing Strategy in Rural South Africa
Introduction
There is growing evidence concerning the acceptability and feasibility of home-based HIV
testing. However, less is known about the cost-effectiveness of the approach yet it is a critical
component to guide decisions about scaling up access to HIV testing. This study examined
the cost-effectiveness of a home-based HIV testing intervention in rural South Africa.
Methods
Two alternatives: clinic and home-based HIV counselling and testing were compared.
Costs were analysed from a providerâs perspective for the period of January to December
2010. The outcome, HIV counselling and testing (HCT) uptake was obtained from the Good
Start home-based HIV counselling and testing (HBHCT) cluster randomised control trial
undertaken in KwaZulu-Natal province. Cost-effectiveness was estimated for a target population
of 22,099 versus 23,864 people for intervention and control communities respectively.
Average costs were calculated as the cost per client tested, while cost-effectiveness was
calculated as the cost per additional client tested through HBHCT
