    A decline in tuberculosis diagnosis, treatment initiation and success during the covid-19 pandemic, using routine health data in Cape Town, South Africa
    (PLoS ONE, 2024) Jennings, Karen; Lembani, Martina; Hesseling, Anneke
    Coronavirus disease (COVID-19) negatively impacted tuberculosis (TB) programs which were already struggling to meet End-TB targets globally. We aimed to quantify and compare diagnosis, treatment initiation, treatment success, and losses along this TB care cascade for drug-susceptible TB in Cape Town, South Africa, prior to and during COVID-19. This observational study used routine TB data within two predefined cohorts: pre-COVID-19 (1 October 2018-30 September 2019) and during-COVID-19 (1 April 2020-31 March 2021). The numbers of people diagnosed, treated for TB and successfully treated were received from the Western Cape Provincial Health Data Centre. Pre and post treatment loss to follow up and cascade success rates (proportion of individuals diagnosed with an outcome of treatment success) were calculated and compared across cohorts, disaggregated by sex, age, HIV status, TB treatment history and mode of diagnosis. There were 27,481 and 19,800 individuals diagnosed with drug-susceptible TB in the pre- and during-COVID-19 cohorts respectively, a relative reduction of 28% (95% CI [27.4% - 28.5%]). Initial loss to follow up increased from 13.4% to 15.2% (p<0.001), while post treatment loss increased from 25.2% to 26.1% (p < 0.033). The overall cascade success rate dropped by 2.1%, from 64.8% to 62.7% (p< 0.001). Pre- and during-COVID-19 cascade success rates were negatively associated with living with HIV and having recurrent TB. An already poorly performing TB program in Cape Town was negatively impacted by the COVID-19 pandemic. There was a substantial reduction in the number of individuals diagnosed with drug-susceptible. Increases in pre-and post-treatment losses resulted in a decline in TB cascade success rates. Strengthened implementation of TB recovery plans is vital, as health services now face an even greater gap between achievements and targets and will need to become more resilient to possible future public health disruptions.

    Access to HIV healthcare services by farm workers in sub-Saharan Africa (SSA): A systematic review protocol
    (BMJ Publishing Group, 2022) Mlangeni, Nosimilo; Adetokunboh, Olatunji; Lembani, Martina
    Sub-Saharan Africa (SSA) region harbours the highest burden of HIV infections in the world. Agricultural work has been reported as one of the occupations with a high prevalence of HIV. Farm workers generally have poor access to health services, which prevents them from receiving proper HIV prevention and care. Furthermore, poor policies and policy implementation, and lack of workplace programmes increases farm workers’ vulnerability to HIV infection. Thus, the aim of this study is to conduct a systematic review to assess HIV prevention and treatment services and national policies governing access to healthcare services by farm workers in SSA.

    COVID-19 and immigrant status: A qualitative study of Malawian immigrants living in South Africa
    (Wiley-Hindawi, 2024) David, Ifeolu; Lembani, Martina; Majee, Wilson
    Migration to South Africa is motivated by the pursuit of employment, safety, and improved living conditions. However, immigrants encounter significant challenges, such as restricted access to essential services, which were exacerbated by the COVID-19 pandemic. This paper investigates the impact of the COVID-19 pandemic on Malawian immigrants in South Africa, addressing the lack of attention given to this immigrant population by highlighting their vulnerabilities. Using a qualitative exploratory and descriptive approach, in-depth interviews were conducted with 24 Malawi immigrants who were over 18 years old and had established residency in South Africa before the onset of the COVID-19 pandemic. Five key stakeholders were also interviewed for additional perspectives and to ensure triangulation and improve data reliability. The interviews were transcribed verbatim and analyzed using thematic analysis strategies and coding with Nvivo12 software. The study highlighted the exacerbated struggles of Malawian immigrants in South Africa amid the COVID-19 pandemic, uncovering systemic discrimination in healthcare, marked by longer wait times and reluctance from health workers to treat undocumented immigrants. The study also revealed a dire security situation, with immigrants living in high-crime areas and feeling particularly targeted due to their foreign status, a situation worsened by the pandemic's economic effects. Additionally, the economic downturn induced by COVID-19 significantly impacted employment opportunities, with many immigrants facing prolonged unemployment and job losses, especially in sectors where they traditionally found work. The detailed accounts of participants highlight not only the multifaceted challenges imposed by the pandemic but also the critical need for inclusive policies and support systems that ensure healthcare access, safety, and economic resilience for immigrants, particularly during global health emergencies. Future research should focus on effective interventions for socioeconomic integration and well-being, particularly for immigrants from other African countries.

    The effects of poor menstrual hygiene management on sexual and reproductive health and education outcomes among adolescent schoolgirls in rural Tanzania
    (University of the Western Cape, 2023) Ngilangwa, David Paul; Lembani, Martina
    Background: In Tanzania, 11 million children are enrolled in primary schools, half of them being girls. As the majority of girls start their menstruation while in primary school, their retention in schools is likely to be hampered by inadequate and poor menstruation hygiene management facilities. It is important to conduct research to understand the association between poor menstruation hygiene management and school absenteeism, psychological well-being, and reproductive tract infections to inform interventions and policies that may enhance the full realization of girls pursuing education successfully. Much research conducted previously has focused on the knowledge and practices of menstruation hygiene management among girls in secondary schools. There is limited evidence of the associations between menstrual hygiene management and particularly sexual and reproductive health and education outcomes, among adolescent schoolgirls in rural Tanzania

    Non-booking for antenatal care and risks for vertical HIV transmission among women in Chitungwiza, Zimbabwe: a cross-sectional study
    (BMC Pregnancy and Childbirth, 2022) Schaay, Nikki; Lembani, Martina; Mandima, Patricia; Ngara, Bernard
    Background: The success of prevention of mother to child transmission of HIV (PMTCT) programs dependents on pregnant women accessing antenatal care (ANC) services. Failure to access ANC throughout the course of pregnancy presents a missed opportunity to fully utilize PMTCT services and a high risk for vertical HIV transmission. Whilst not booking for ANC was about 6% in Zimbabwe, according to the 2015 Zimbabwe Demographic and Health Survey, it is important to determine the local burden of pregnant women both un-booked for ANC and living with HIV. in Chitungwiza city, to inform local response. This study aimed at determining the proportion of women un-booked for antenatal care and among them, the proportion of women who were with HIV and to identify risk factors associated with not-booking for ANC in Chitungwiza city in Zimbabwe.

    Post-doctoral research fellowship as a health policy and systems research capacity development intervention: a case of the CHESAI initiative
    (BioMed Central, 2016) Lembani, Martina; Teddy, Gina; Molosiwa, Dintle; Hwabamungu, Boroto
    BACKGROUND: Building capacity in health policy and systems research (HPSR), especially in low- and middle-income countries, remains a challenge. Various approaches have been suggested and implemented by scholars and institutions using various forms of capacity building to address challenges regarding HPSR development. The Collaboration for Health Systems Analysis and Innovation (CHESAI) – a collaborative effort between the Universities of Cape Town and the Western Cape Schools of Public Health – has employed a non-research based post-doctoral research fellowship (PDRF) as a way of building African capacity in the field of HPSR by recruiting four post-docs. In this paper, we (the four post-docs) explore whether a PDRF is a useful approach for capacity building for the field of HPSR using our CHESAI PDRF experiences. METHODS: We used personal reflections of our written narratives providing detailed information regarding our engagement with CHESAI. The narratives were based on a question guide around our experiences through various activities and their impacts on our professional development. The data analysis process was highly iterative in nature, involving repeated meetings among the four post-docs to reflect, discuss and create themes that evolved from the discussions. RESULTS: The CHESAI PDRF provided multiple spaces for our engagement and capacity development in the field of HPSR. These spaces provided us with a wide range of learning experiences, including teaching and research, policy networking, skills for academic writing, engaging practitioners, co-production and community dialogue. Our reflections suggest that institutions providing PDRF such as this are valuable if they provide environments endowed with adequate resources, good leadership and spaces for innovation. Further, the PDRFs need to be grounded in a community of HPSR practice, and provide opportunities for the post-docs to gain an in-depth understanding of the broader theoretical and methodological underpinnings of the field. CONCLUSION: The study concludes that PDRF is a useful approach to capacity building in HPSR, but it needs be embedded in a community of practice for fellows to benefit. More academic institutions in Africa need to adopt innovative and flexible support for emerging leaders, researchers and practitioners to strengthen our health systems

    Structural barriers and facilitators to accessing HIV services for marginalized working populations: insights from farm workers in South Africa
    (Oxford University Press, 2025) Lembani, Martina; Mlangeni, Nosimilo; Adetokunboh, Olatunji
    Farm workers are vulnerable working populations who face significant inequalities in accessing health services, including those for human immunodeficiency virus (HIV) prevention, treatment and care. This descriptive phenomenological study aimed to explore farm workers’ experiences when accessing HIV services and was conducted in Limpopo province, South Africa. Eighteen in-depth interviews were conducted in four health facilities from two districts, and two focus group discussions were conducted in one of the farms within the province. Purposive sampling and systematic random sampling were used to select study participants. A deductive thematic approach was used to analyse data, informed by the social–ecological model of health. The results reveal that farm workers perceive multiple interdependent factors that inhibit or enable their access to HIV healthcare services. Key barriers to HIV healthcare were transport affordability, health worker attitudes, stigma and discrimination, models of HIV healthcare delivery, geographic location of health facilities and difficult working conditions. Key facilitators to HIV healthcare included the availability of mobile health services, the presence of community health workers and a supportive work environment. The findings suggest disparities in farm workers’ access to HIV services, with work being the main determinant of access. We, therefore, recommend a review of HIV policies and programmes for the agricultural sector and models of HIV healthcare delivery that address the unique needs of farm workers.

    Supporting community health workers in South Africa for context-specific food and nutrition literacy: implementation of a multi-media education-entertainment intervention
    (BioMed Central Ltd, 2025) Alaba, Olufunke; Lembani, Martina; Mchiza, Zandile
    Background: Multimedia technology, recognized for its efficacy in education, offers a complementary approach to traditional health education. In South Africa, community health workers (CHWs) play a pivotal role in improving population health, but often lack comprehensive health knowledge. This study explores the effectiveness of using a multimedia education-entertainment (MM-EE) intervention to enhance food and nutrition literacy among CHWs in resource-challenged townships. Methods: Seventy-seven participants completed a baseline and 6-month post-intervention follow-up survey. The MM-EE intervention comprised short stories conveyed via comic booklets and 30-second video clips, covering food knowledge, use of food labels, meal preparation, planning, and eating behaviour. Materials were distributed via mobile messaging services, including WhatsApp (as the primary social media platform), MMS, and SMS. Descriptive statistics, chi-square tests, Wilcoxon signed-rank tests, and multivariate linear regression were conducted using R studio version 4.3.3. Results: Over 70% of participants were classified as having obesity, and 18.2% as overweight, leading to 88.3% of participants being classified as overweight or having obesity. A significant proportion of participants (68.8%) reported having an existing non-communicable disease (NCD). The MM-EE intervention significantly improved CHWs’ food and nutrition literacy, reflected in improved median scores for meal preparation (43.1% [IQR: 19.6] pre- vs. 62.7% [IQR: 11.7] post-intervention), planning (58.6% [IQR: 12.1] pre- vs. 67.2% [IQR: 13.4] post-intervention), and overall food and nutrition literacy (63.0% [IQR: 8.1] pre- vs. 69.4% [IQR: 10.9] post-intervention; p <.001). Conclusion: The study showed effective MM-EE intervention outcomes, positioning this method of health dissemination as suitable for improving the food and nutrition literacy of CHWs in South Africa. The study suggests the potential effectiveness of MM-EE approaches to enhance the health knowledge of the South African population. However, adaptation for the wider population will require further research on scalability, sustainability and an improved intervention design to address all dimensions of literacy.

    Understanding key drivers of performance in the provision of maternal health services in eastern cape, South Africa: a systems analysis using group model building
    (BMC, 2018) Lembani, Martina; de Pinho, Helen; Delobelle, Peter
    Background: The Eastern Cape Province reports among the poorest health service indicators in South Africa with some of its districts standing out as worst performing as regards maternal health indicators. To understand key drivers and outcomes of this underperformance and to explore whether a participatory analysis could deepen action-oriented understanding among stakeholders, a study was conducted in one of the chronically poorly performing districts. Methods: The study used a systems analysis approach to understand the drivers and outcomes affecting maternal health in the district in order to identify key leverage points for addressing the situation. The approach included semistructured interviews with a total of 24 individuals consisting health system managers at various levels, health facility staff and patients. This was followed by a participatory group model building exercise with 23 key stakeholders to analyze system factors and their interrelationships affecting maternal health in the district using rich pictures and interrelationship diagraphs (IRDs) and finally the development of causal loop diagrams (CLDs). Results: The stakeholders were able to unpack the complex ways in which factors were interrelated in contributing to poor maternal health performance and identified the feedback loops which resulted in the situation being intractable, suggesting strategies for sustainable improvement. Quality of leadership was shown to have a pervasive influence on overall system performance by linking to numerous factors and feedback loops, including staff motivation and capacity building. Staff motivation was linked to quality of care in turn influencing patient attendance and feeding back into staff motivation through its impact on workload. Without attention to workload, patient waiting times and satisfaction, the impact of improved leadership and staff support on staff competence and attitudes would be diminished. Conclusion: Understanding the complex interrelationships of factors in the health system is key to identifying workable solutions especially in the context of chronic health systems challenges. Systems modelling using group model building methods can be an efficient means of supporting stakeholders to recognize valuable resources within the context of a dysfunctional system to strengthen systems performance.
