The COVID-19 pandemic has led to an explosion of online research using rating scales. While this approach can be useful, two of the major challenges affecting the quality of this type of research ...include selection bias and the use of non-validated scales. Online research is prone to various forms of selection bias, including self-selection bias, non-response bias or only reaching specific subgroups. The use of rating scales requires contextually validated scales that meet psychometrical properties such as validity, reliability and—for cross-country comparisons—invariance across settings. We discuss options to prevent or tackle these challenges. Researchers, readers, editors and reviewers need to take a critical stance towards research using this type of methodology.
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. This proposed scoping review will follow Arksey and O'Malley's methodological framework for conducting scoping reviews as refined by Levac et al. The review will follow the Joanna Briggs Institute's manual for conducting scoping reviews. Literature searches will be conducted using six databases: Academic search complete; APA PsycArticles; CINAHL; MEDLINE; SocINDEX and Web of science. Title screening will see the "Participant, Concept, Context" framework applied to identify relevant literature and will not include the appraisal of search results. Data charting will follow an adapted version of Trico and colleagues' PRISMA-ScR and results will be mapped descriptively and in tabular format. Furthermore, results will be discussed within the syndemics model of health, and summarised as a biosocial conceptual model.
In response to the COVID-19 pandemic, South Africa implemented a strict stay-at-home order. The mental health effects of the pandemic and related containment measures are minimally documented in this ...region. This study examines the association between COVID-19 related stressors and mental health during a strict stay-at-home order in South Africa. A total of 860 self-selected participants residing in the Western Cape province completed an online survey from 20-31 May 2020. This sample consisted mainly of higher socioeconomic and higher educated segments of the population. Structural equation modelling was used to assess how sociodemographic factors, membership of vulnerable groups and COVID-19 related stressors were associated with PHQ-9 (depression) and GAD-7 (anxiety) scores. 46.0% and 47.2% of participants met the diagnostic threshold of anxiety and depressive disorder, respectively. Considerable daily life repercussions were linked to these scores. Among these participants, less than 20% consulted a formal practitioner and this was 12% for participants without a pre-existing mental health condition. Distress related to containment measures and distress about being infected were significantly associated with more anxiety and depressive symptoms. Having a pre-existing mental health condition was associated with poorer mental health, but being an active health worker was not. Younger age, being female, and living in a non-rural area were associated with poorer mental health. Our findings suggest a considerable mental health impact of this pandemic and related containment measures, but low attendance of mental health services. The accessibility to tailored mental health support is essential under these circumstances, especially for vulnerable groups.
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 'implementation units' - a district hospital and surrounding primary health care services - 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 Miller's typology of the forms of power - namely 'power over', 'power to', 'power within' and 'power with'.
Multiple expressions of actor power were evident during implementation and played a plausible role in shaping variable implementation, while the intervention itself acted to change power relations. As expected, a degree of buy-in of managers (with power over) in implementation units was necessary for the intervention to proceed. Beyond this, the ability to mobilise collective action (power with), combined with support from champions with agency (power within) were key to successful implementation. However, local empowerment may pose a threat to hierarchical power (power over) at higher levels (district and provincial) of the system, potentially affecting sustainability.
A systematic approach to the analysis of power in implementation research may provide insights into the fate of interventions. Intervention designs need to consider how they shape power relations, especially where interventions seek to widen participation and responsiveness in local health systems.
The continuum of care is a recommended framework for comprehensive health service delivery for maternal health, and it integrates health system and social determinants of health. There is a current ...lack of knowledge on a measurement approach to monitor performance on the framework. In this study we aim to develop and test a composite index for assessing the maternal health continuum in a province in South Africa with the possibility of nationwide use. The composite index was computed as a geometric mean of four dimensions of adequacy of the continuum of care. Data was sourced from the district health information system, household surveys and the census. The index formula was tested for robustness when alternative inputs for indicators and standardization methods were used. The index was used to assess performance in service delivery in the North West province of South Africa, as well as its four districts over a five-year period (2013-2017). The index was validated by assessing associations with maternal health and other outcomes. And factor analysis was used to assess the statistical dimensions of the index. The provincial level index score increased from 62.3 in 2013 to 74 in 2017, showing general improvement in service delivery over time. The district level scores also improved over time, and our analysis identified areas for performance improvement. These include social determinants of health in some districts, and access and linkages to care in others. The provincial index was correlated with institutional maternal mortality rates (r.sub.s = -0.90, 90% CI = (-1.00, -0.25)) and the Human Development Index (r = 0.97, 95% CI = (0.63, 0.99). It was robust to alternative approaches including z-score standardization of indicators. Factor analysis showed three groupings of indicators for the health system and social determinants of health. This study demonstrated the development and testing of a composite index to monitor and assess service delivery on the continuum of care for maternal health. The index was shown to be robust and valid, and identified potential areas for service improvement. A contextualised version can be tested in other settings within and outside of South Africa.
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.
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.
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.
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.
District-level initiatives to improve maternal, neonatal and child health (MNCH) generally do not take governance as their primary lens on health system strengthening. This paper is a case study of a ...district and sub-district governance mechanism, the Monitoring and Response Unit (MRU), which aimed to improve MNCH outcomes in two districts of South Africa. The MRU was introduced as a decision-making and accountability structure, and constituted of a "triangle" of managers, clinicians and information officers. An independent evaluation of the MRU initiative was conducted, three years after establishment, involving interviews with 89 district actors. Interviewees reported extensive changes in the scope, quality and organization of MNCH services, attributing these to the introduction of the MRU and enhanced support from district clinicians. We describe both the formal and informal aspects of the MRU as a governance mechanism, and then consider the pathways through which the MRU plausibly acted as a catalyst for change, using the institutional constructs of credible commitment, coordination and cooperation. In particular, the MRU promoted the formation of non-hierarchical collaborative networks; improved coordination between community, PHC and hospital services; and shaped collective sense-making in positive ways. We conclude that innovations in governance could add significant value to the district health system strengthening for improved MNCH. However, this requires a shift in focus from strengthening the front-line of service delivery, to change at the meso-level of sub-district and district decision-making; and from purely technical, data-driven to more holistic approaches that engage collective mindsets, widen participation in decision-making and nurture political leadership skills.
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.
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.
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 'community dialogues' 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.
These features resonate with the deliberative, multi-level and context sensitive approaches described as the "simple rules" 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 implementation.
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.
Two alternatives: clinic and home-based HIV counselling and testing were compared. Costs were analysed from a provider's 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.
Based on effectiveness of 37% in the intervention (HBHCT) arm compared to 16% in control arm, home based testing costs US$29 compared to US$38 per person for clinic HCT. The incremental cost effectiveness per client tested using HBHCT was $19.
HBHCT was less costly and more effective. Home-based HCT could present a cost-effective alternative for rural 'hard to reach' populations depending on affordability by the health system, and should be considered as part of community outreach programs.
Overweight and obese women face various reproductive and other health challenges, and in some cases, even mortality. Despite evidence of rural-urban disparities in overweight and obesity among women ...of reproductive age, there is limited evidence regarding the predictors of these disparities. This study aims to investigate the factors associated with overweight and obesity and examine the contributors to rural-urban disparities in overweight and obesity among women of reproductive age in Nigeria.
We utilized the 2018 Nigeria Demographic and Health Survey dataset. The survey employed a two-stage cluster sampling technique based on Nigeria's 2006 census enumeration areas for sample selection. Overweight and obesity were defined as a body mass index (BMI) ≥ 25. Data analyses were conducted using the Logistic Regression Model and the threefold Blinder-Oaxaca decomposition model (α0.05).
The study revealed that older women (OR = 2.44; CI = 2.11-2.83), those with higher wealth (OR = 2.05; CI = 1.81-2.31), contraceptive users (OR = 1.41; CI = 1.27-1.57), and residents of the South-South region (OR = 1.24; CI = 1.07-1.45) were more likely to be overweight/obese. The decomposition analysis indicated that the mean predicted prevalence of overweight and obesity is 35.5% in urban areas, compared to 21.1% in rural areas of Nigeria. Factors such as wealth status, educational level, media exposure, and contraceptive use were identified as significant contributors to these disparities.
The findings underscore the importance of addressing socioeconomic disparities when designing healthcare interventions to reduce the burden of overweight and obesity, particularly in urban areas. Prioritizing these factors can facilitate efforts to promote healthier lifestyles and enhance overall well-being.
