The future of public health doctoral education in Africa: transforming higher education institutions to enhance research and practice.

The African Union and the Africa Centers for Disease Control and Prevention issued a Call to Action in 2022 for Africa's New Public Health Order that underscored the need for increased capacity in the public health workforce. Additional domestic and global investments in public health workforce development are central to achieving the aspirations of Agenda 2063 of the African Union, which aims to build and accelerate the implementation of continental frameworks for equitable, people-centred growth and development. Recognising the crucial role of higher education and research, we assessed the capabilities of public health doctoral training in schools and programmes of public health in Africa across three conceptual components: instructional, institutional, and external. Six inter-related and actionable recommendations were derived to advance doctoral training, research, and practice capacity within and between universities. These can be achieved through equitable partnerships between universities, research centres, and national, regional, and global public health institutions.

Understanding of 'generalist medical practice' in South African medical schools.

BACKGROUND: In South Africa, medical students are expected to have acquired a generalist competence in medical practice on completion of their training. However, what the students and their preceptors understand by 'generalist medical practice' has not been established in South African medical schools. AIM: This study aimed to explore what the students and their preceptors understood by 'generalist medical practice'. SETTING: Four South African medical schools: Sefako Makgatho Health Sciences University, University of KwaZulu-Natal, Walter Sisulu University and the University of the Witwatersrand. METHODS: The exploratory descriptive qualitative design was used. Sixteen focus group discussions (FGDs) and 27 one-on-one interviews were conducted among students and their preceptors, respectively. Participants were recruited through purposive sampling. The inductive and deductive data analysis methods were used. The MAXQDA 2020 (Analytics Pro) software was used to arrange data, yielding 2179 data segments. RESULTS: Ten themes were identified: (1) basic knowledge of medicine, (2) first point of contact with all patients regardless of their presenting problems, (3) broad field of common conditions prevalent in the community, (4) dealing with the undifferentiated patient without a diagnosis, (5) stabilising emergencies before referral, (6) continuity, (7) coordinated and (8) holistic patient care, necessitating nurturance of doctor-patient relationship, (9) health promotion and disease prevention, and (10) operating mainly in primary health care settings. CONCLUSION: The understanding of 'generalist medical practice' in accordance with internationally accepted principles augurs well in training undergraduate medical students on the subject. However, interdepartmental collaboration on the subject needs further exploration.Contribution: The study's findings can be used as a guide upon which the students' preceptors and their students can reflect during the training in generalist medical practice.

Primary health care in practice: usual source of care and health system performance across 14 countries.

Primary health care (PHC) is central to attainment of the Sustainable Development Goals, yet comparable cross-country data on key aspects of primary care have not been widely available. This study analysed data from the People's Voice Survey, which was conducted in 2022 and 2023 in 14 countries. We documented usual source of care across countries and examined associations of usual source of care with core PHC services, quality ratings, and health system confidence. We found that 75% of respondents had a usual source of care, and that 40% of respondents accessed usual care in the public sector at primary level. 44% rated their usual source of care as very good or excellent. Access to PHC-linked screenings and treatments varied widely within and across countries. Having any usual source of care was associated with higher take-up of preventive services, greater access to treatment including mental health services, and greater health system endorsement. Strengthening links between health system users and primary care providers could improve take-up of preventive care and increase user satisfaction with health system performance.

Population confidence in the health system in 15 countries: results from the first round of the People's Voice Survey.

Population confidence is essential to a well functioning health system. Using data from the People's Voice Survey-a novel population survey conducted in 15 low-income, middle-income, and high-income countries-we report health system confidence among the general population and analyse its associated factors. Across the 15 countries, fewer than half of respondents were health secure and reported being somewhat or very confident that they could get and afford good-quality care if very sick. Only a quarter of respondents endorsed their current health system, deeming it to work well with no need for major reform. The lowest support was in Peru, the UK, and Greece-countries experiencing substantial health system challenges. Wealthy, more educated, young, and female respondents were less likely to endorse the health system in many countries, portending future challenges for maintaining social solidarity for publicly financed health systems. In pooled analyses, the perceived quality of the public health system and government responsiveness to public input were strongly associated with all confidence measures. These results provide a post-COVID-19 pandemic baseline of public confidence in the health system. The survey should be repeated regularly to inform policy and improve health system accountability.

Organisation of care for people receiving drug-resistant tuberculosis treatment in South Africa: a mixed methods study.

OBJECTIVES: Treatment for multidrug-resistant/rifampicin-resistant tuberculosis (MDR/RR-TB) is increasingly transitioning from hospital-centred to community-based care. A national policy for decentralised programmatic MDR/RR-TB care was adopted in South Africa in 2011. We explored variations in the implementation of care models in response to this change in policy, and the implications of these variations for people affected by MDR/RR-TB. DESIGN: A mixed methods study was done of patient movements between healthcare facilities, reconstructed from laboratory records. Facility visits and staff interviews were used to determine reasons for movements. PARTICIPANTS AND SETTING: People identified with MDR/RR-TB from 13 high-burden districts within South Africa. OUTCOME MEASURES: Geospatial movement patterns were used to identify organisational models. Reasons for patient movement and implications of different organisational models for people affected by MDR/RR-TB and the health system were determined. RESULTS: Among 191 participants, six dominant geospatial movement patterns were identified, which varied in average hospital stay (0-281 days), average patient distance travelled (12-198 km) and number of health facilities involved in care (1-5 facilities). More centralised models were associated with longer delays to treatment initiation and lengthy hospitalisation. Decentralised models facilitated family-centred care and were associated with reduced time to treatment and hospitalisation duration. Responsiveness to the needs of people affected by MDR/RR-TB and health system constraints was achieved through implementation of flexible models, or the implementation of multiple models in a district. CONCLUSIONS: Understanding how models for organising care have evolved may assist policy implementers to tailor implementation to promote particular patterns of care organisation or encourage flexibility, based on patient needs and local health system resources. Our approach can contribute towards the development of a health systems typology for understanding how policy-driven models of service delivery are implemented in the context of variable resources.

What do medical students and their clinical preceptors understand by primary health care in South Africa? A qualitative study.

BACKGROUND: The definition of Primary Health Care (PHC) issued by the World Health Organisation in 1978 indicated that essential health care should be made accessible to individuals and their communities close to where they live and work. In 1992 Starfield articulated the four pillars of PHC: the patient's first contact with healthcare, comprehensive care, coordinated care and continuous care. Using this literature guidance, this study sought to explore what undergraduate medical students and their clinical preceptors understood by PHC in four South African medical schools. METHODS: A qualitative study using the phenomenological design was conducted among undergraduate medical students and their clinical preceptors. The setting was four medical schools in South Africa (Sefako Makgatho Health Sciences University, Walter Sisulu University and the University of KwaZulu-Natal and the Witwatersrand University). A total of 27 in-depth interviews were conducted among the clinical preceptors and 16 focus group discussions among the students who were in their clinical years of training (MBChB 4-6). Interviews were digitally recorded and transcribed verbatim, followed by thematic data analysis using the MAXQDA 2020 (Analytics Pro) software. RESULTS: Four themes were identified in which there were similarities between the students and their preceptors regarding their understanding of PHC: (1) PHC as the patient's first contact with the healthcare system; (2) comprehensive care; (3) coordination of care and (4) continuity of care. A further two themes were identified in which these two groups were not of similar understanding: (5) PHC as a level or an approach to healthcare and (6) the role of specialist clinical preceptors in PHC. CONCLUSIONS: Medical students and their clinical preceptors displayed an understanding of PHC in line with four pillars articulated by Starfield and the WHO definition of PHC. However, there remains areas of divergence, on which the medical schools should follow the guidance provided by the WHO and Starfield for a holistic understanding of PHC.

Access to digital media and devices among adolescents in sub-Saharan Africa: A multicountry, school-based survey.

Digital technologies provide unprecedented opportunities for health and nutrition interventions among adolescents. The use of digital media and devices among young adolescents across diverse settings in sub-Saharan Africa is unclear. This cross-sectional study aimed to assess the use of digital media and devices and the socioeconomic determinants of use among young adolescents in Burkina Faso, Ethiopia, South Africa, Sudan and Tanzania. The study included 4981 adolescents aged 10-15 from public schools selected by multistage sampling. Access to various digital media and devices was self-reported by adolescents. Logistic regression models were used to estimate the odds ratios (ORs) and 95% confidence intervals (CIs) for the associations between sociodemographic characteristics and access to digital media and devices. Approximately 40% of the adolescents in Burkina Faso and South Africa, 36% in Sudan, 13% in Ethiopia and 3% in Tanzania owned mobile phones. Compared with boys, girls had a lower ownership of mobile phones (odds ratio [OR] = 0.79; 95% confidence interval [CI]: 0.68, 0.92; p = 0.002), computers (OR = 0.83; 95% CI: 0.70, 0.99; p = 0.04) and social media accounts (OR = 0.68; 95% CI: 0.56, 0.83; p < 0.001). Higher maternal education and greater household wealth were positively associated with access to digital media and devices. While digital media and devices are promising platforms for interventions in some settings due to relatively high levels of access, their utility in delivering health and nutrition interventions to adolescents in these contexts should be further examined.

Adolescent health and well-being in sub-Saharan Africa: Strengthening knowledge base and research capacity through a collaborative multi-country school-based study.

In Sub-Saharan Africa (SSA), adolescents make up around one-quarter of the population who are growing up in a rapidly urbanizing environment, with its associated risks and benefits, including impacts on health, psychosocial development, nutrition, and education. However, research on adolescents' health and well-being in SSA is limited. The ARISE (African Research, Implementation Science and Education) Network's Adolescent Health and Nutrition Study is an exploratory, school-based study of 4988 urban adolescents from five countries: Burkina Faso, Ethiopia, South Africa, Sudan, and Tanzania. A multistage random sampling strategy was used to select the schools and adolescents. Adolescent boys and girls aged 10-15 years were interviewed using a standardized questionnaire by trained enumerators. The questionnaire covered multiple domains including demographic and socioeconomic characteristics, water, sanitation and hygiene practices, antimicrobial resistance, physical activity, dietary behaviours, socioemotional development, educational outcomes, media use, mental health, and menstrual hygiene (only for girls). Additionally, a desk review of health and school meal policies and programs and a qualitative investigation into health and food environments in schools were conducted with students, administrators, and food vendors. In this paper, we describe the study design and questionnaire, present profiles of young adolescents who participated in the study, and share field experiences and lessons learned for future studies. We expect that this study along with other ARISE Network projects will be a first step toward understanding young people's health risks and disease burdens, identifying opportunities for interventions and improving policies, as well as developing potential research capacities on adolescent health and well-being in the SSA region.

An economic incentive package to support the wellbeing of caregivers of adolescents living with HIV during the COVID-19 pandemic in South Africa: a feasibility study protocol for a pilot randomised trial.

BACKGROUND: The mental and financial strain linked to unpaid caregiving has been amplified during the COVID-19 pandemic. In sub-Saharan Africa, carers of adolescents living with HIV (ALHIV) are critical for maintenance of optimum HIV treatment outcomes. However, the ability of caregivers to provide quality care to ALHIV is undermined by their ability to maintain their own wellbeing due to multiple factors (viz. poverty, stigma, lack of access to social support services) which have been exacerbated by the COVID-19 pandemic. Economic incentives, such as cash incentives combined with SMS reminders, have been shown to improve wellbeing. However, there is a lack of preliminary evidence on the potential of economic incentives to promote caregiver wellbeing in this setting, particularly in the context of a pandemic. This protocol outlines the design of a parallel-group pilot randomised trial comparing the feasibility and preliminary effectiveness of an economic incentive package versus a control for improving caregiver wellbeing. METHODS: Caregivers of ALHIV will be recruited from public-sector HIV clinics in the south of the eThekwini municipality, KwaZulu-Natal, South Africa. Participants will be randomly assigned to one of the following groups: (i) the intervention group (n = 50) will receive three cash payments (of ZAR 350, approximately 23 USD), coupled with a positive wellbeing message over a 3-month period; (ii) the control group (n = 50) will receive a standard message encouraging linkage to health services. Participants will be interviewed at baseline and at endline (12 weeks) to collect socio-demographic, food insecurity, health status, mental health (stigma, depressive symptoms) and wellbeing data. The primary outcome measure, caregiver wellbeing, will be measured using the CarerQoL instrument. A qualitative study will be conducted alongside the main trial to understand participant views on participation in the trial and their feedback on study activities. DISCUSSION: This study will provide scientific direction for the design of a larger randomised controlled trial exploring the effects of an economic incentive for improving caregiver wellbeing. The feasibility of conducting study activities and delivering the intervention remotely in the context of a pandemic will also be provided. TRIAL REGISTRATION: PACTR202203585402090.

South African University Staff and Students' Perspectives, Preferences, and Drivers of Hesitancy Regarding COVID-19 Vaccines: A Multi-Methods Study.

COVID-19 vaccine hesitancy poses a threat to the success of vaccination programmes currently being implemented. Concerns regarding vaccine effectiveness and vaccine-related adverse events are potential barriers to vaccination; however, it remains unclear whether tailored messaging and vaccination programmes can influence uptake. Understanding the preferences of key groups, including students, could guide the implementation of youth-targeted COVID-19 vaccination programmes, ensuring optimal uptake. This study examined university staff and students' perspectives, preferences, and drivers of hesitancy regarding COVID-19 vaccines. A multi-methods approach was used-an online convenience sample survey and discrete choice experiment (DCE)-targeting staff and students at the University of KwaZulu-Natal, South Africa. The survey and DCE were available for staff and students, and data were collected from 18 November to 24 December 2021. The survey captured demographic characteristics as well as attitudes and perspectives of COVID-19 and available vaccines using modified Likert rating questions adapted from previously used tools. The DCE was embedded within the survey tool and varied critical COVID-19 vaccine programme characteristics to calculate relative utilities (preferences) and determine trade-offs. A total of 1836 staff and students participated in the study (541 staff, 1262 students, 33 undisclosed). A total of 1145 (62%) respondents reported that they had been vaccinated against COVID-19. Vaccination against COVID-19 was less prevalent among students compared with staff (79% of staff vs. 57% of students). The vaccine's effectiveness (22%), and its safety (21%), ranked as the two dominant reasons for not getting vaccinated. These concerns were also evident from the DCE, with staff and students being significantly influenced by vaccine effectiveness, with participants preferring highly effective vaccines (90% effective) as compared with those listed as being 70% or 50% effective (ß = -3.72, 95% CI = -4.39 to -3.04); this characteristic had the strongest effect on preferences of any attribute. The frequency of vaccination doses was also found to have a significant effect on preferences with participants deriving less utility from choice alternatives requiring two initial vaccine doses compared with one dose (ß = -1.00, 95% CI = -1.42 to -0.58) or annual boosters compared with none (ß = -2.35, 95% CI = -2.85 to -1.86). Notably, an incentive of ZAR 350 (USD 23.28) did have a positive utility (ß = 1.14, 95% CI = 0.76 to 1.53) as compared with no incentive. Given the slow take-up of vaccination among youth in South Africa, this study offers valuable insights into the factors that drive hesitancy among this population. Concerns have been raised around the safety and effectiveness of vaccines, although there remains a predilection for efficient services. Respondents were not enthusiastic about the prospect of having to take boosters, and this has played out in the roll-out data. Financial incentives may increase both the uptake of the initial dose of vaccines and see a more favourable response to subsequent boosters. Universities should consider tailored messaging regarding vaccine effectiveness and facilitate access to vaccines, to align services with the stated preferences of staff and students.

Health Insurance Coverage In Low- And Middle-Income Countries Remains Far From The Goal Of Universal Coverage.

This study aimed to determine levels of health insurance coverage in low- and middle-income countries and how coverage varies by people's sociodemographic characteristics. We conducted a population size-weighted, one-stage individual participant data meta-analysis of health insurance coverage, using a population-based sample of 2,035,401 participants ages 15-59 from nationally representative household surveys in fifty-six countries during the period 2006-18. One in five people (20.3 percent) across the fifty-six countries in our study had health insurance. Health insurance coverage exceeded 50 percent in only seven countries and 70 percent in only three countries. Substantially more people had public health insurance than private health insurance (71.4 percent versus 28.6 percent). We found that men and older, more educated, and wealthier people were more likely to have health insurance; these sociodemographic gradients in health insurance coverage were strongest in sub-Saharan Africa and followed traditional lines of privilege. Low- and middle-income countries need to massively expand health insurance coverage if they intend to use insurance to achieve universal health coverage.

Hosting ICASA 2021 in South Africa amidst the global Omicron scare.

The 21st International Conference on HIV/AIDS and STI's in Africa (ICASA) was successfully held from the 6th to 11t h December 2021 in Durban, South Africa. Little did we know at the time of planning that COVID-19 could become such a formidable force in eroding the progress made to bring lifesaving therapies among vulnerable communities in Africa. The conference also highlighted Africa's openness to the world, also shown in the way South Africa shared data on its discovery of the Omicron variant. Arguably the most important of lessons is that integrated HIV/TB services have become a platform on which to provide other services. We also saw how HIV and TB services were used as leverage for COVID-19 services. Much was also discussed about the need to adopt more self-care approaches, as was demonstrated with the increased use of self-testing technologies for HIV, and potentially other health needs. It's clear that Africa needs to increase its capacity to support and enable innovation, particularly in the design and manufacturing of new technologies including diagnostics, vaccines and therapeutics.

COVID-19 and resilience of healthcare systems in ten countries.

Declines in health service use during the Coronavirus Disease 2019 (COVID-19) pandemic could have important effects on population health. In this study, we used an interrupted time series design to assess the immediate effect of the pandemic on 31 health services in two low-income (Ethiopia and Haiti), six middle-income (Ghana, Lao People's Democratic Republic, Mexico, Nepal, South Africa and Thailand) and high-income (Chile and South Korea) countries. Despite efforts to maintain health services, disruptions of varying magnitude and duration were found in every country, with no clear patterns by country income group or pandemic intensity. Disruptions in health services often preceded COVID-19 waves. Cancer screenings, TB screening and detection and HIV testing were most affected (26-96% declines). Total outpatient visits declined by 9-40% at national levels and remained lower than predicted by the end of 2020. Maternal health services were disrupted in approximately half of the countries, with declines ranging from 5% to 33%. Child vaccinations were disrupted for shorter periods, but we estimate that catch-up campaigns might not have reached all children missed. By contrast, provision of antiretrovirals for HIV was not affected. By the end of 2020, substantial disruptions remained in half of the countries. Preliminary data for 2021 indicate that disruptions likely persisted. Although a portion of the declines observed might result from decreased needs during lockdowns (from fewer infectious illnesses or injuries), a larger share likely reflects a shortfall of health system resilience. Countries must plan to compensate for missed healthcare during the current pandemic and invest in strategies for better health system resilience for future emergencies.

A Perspective on Implementation Outcomes and Strategies to Promote the Uptake of COVID-19 Vaccines.

Recent articles have highlighted the importance of incorporating implementation science concepts into pandemic-related research. However, limited research has been documented to date regarding implementation outcomes that may be unique to COVID-19 vaccinations and how to utilize implementation strategies to address vaccine program-related implementation challenges. To address these gaps, we formed a global COVID-19 implementation workgroup of implementation scientists who met weekly for over a year to review the available literature and learn about ongoing research during the pandemic. We developed a hierarchy to prioritize the applicability of "lessons learned" from the vaccination-related implementation literature. We identified applications of existing implementation outcomes as well as identified additional implementation outcomes. We also mapped implementation strategies to those outcomes. Our efforts provide rationale for the utility of using implementation outcomes in pandemic-related research. Furthermore, we identified three additional implementation outcomes: availability, health equity, and scale-up. Results include a list of COVID-19 relevant implementation strategies mapped to the implementation outcomes.

A Continuous Quality Improvement Intervention to Improve Antenatal HIV Care Testing in Rural South Africa: Evaluation of Implementation in a Real-World Setting.

BACKGROUND: We evaluated continuous quality improvement (CQI) targeting antenatal HIV care quality in rural South Africa using a stepped-wedge cluster-randomised controlled trial (Management and Optimisation of Nutrition, Antenatal, Reproductive, Child health, MONARCH) and an embedded process evaluation. Here, we present results of the process evaluation examining determinants of CQI practice and 'normalisation.' METHODS: A team of CQI mentors supported public-sector health workers in seven primary care clinics to (1) identify root causes of poor HIV viral load (VL) monitoring among pregnant women living with HIV and repeat HIV testing among pregnant women not living with HIV, and (2) design and iteratively test their own solutions. We used a mixed methods evaluation with field notes from CQI mentors ('dose' and 'reach' of CQI, causes of poor HIV care testing rates, implemented change ideas); patient medical records (HIV care testing by clinic and time step); and semi-structured interviews with available health workers. We analysed field notes andsemi-structured interviews for determinants of CQI implementation and 'normalisation' using Normalisation Process Theory (NPT) and Tailored Implementation of Chronic Diseases (TICD) frameworks. RESULTS: All interviewed health workers found the CQI mentors and methodology helpful for quality improvement. Total administered 'dose' was higher than planned but 'reach' was limited by resource constraints, particularly staffing shortages. Simple workable improvements to identified root causes were implemented, such as a patient tracking notebook and results filing system. VL monitoring improved over time, but not repeat HIV testing. Besides resource constraints, gaps in knowledge of guidelines, lack of leadership, poor clinical documentation, and data quality gaps reduced CQI implementation fidelity and normalisation. CONCLUSION: While CQI holds promise, we identified several health system challenges. Priorities for policy makers include improving staffing and strategies to improve clinical documentation. Additional support with implementing clinical guidelines and improving routine data quality are needed. Normalising CQI may be challenging without concurrent health system improvements.

The role of emergent champions in policy implementation for decentralised drug-resistant tuberculosis care in South Africa.

OBJECTIVE: Champions are recognised as important to driving organisational change in healthcare quality improvement initiatives in high-income settings. In low-income and middle-income countries with a high disease burden and constrained human resources, their role is highly relevant yet understudied. Within a broader study on policy implementation for decentralised drug-resistant tuberculosis care in South Africa, we characterised the role, strategies and organisational context of emergent policy champions. DESIGN: Interviews with 34 healthcare workers in three South African provinces identified the presence of individuals who had a strong influence on driving policy implementation forward. Additional interviews were conducted with 13 participants who were either identified as champions in phase II or were healthcare workers in facilities in which the champions operated. Thematic analyses using a socio-ecological framework further explored their strategies and the factors enabling or obstructing their agency. RESULTS: All champions occupied senior managerial posts and were accorded legitimacy and authority by their communities. 'Disease-centred' champions had a high level of clinical expertise and placed emphasis on clinical governance and clinical outcomes, while 'patient-centred' champions promoted pathways of care that would optimise patients' recovery while minimising disruption in other spheres of their lives. Both types of champions displayed high levels of resourcefulness and flexibility to adapt strategies to the resource-constrained organisational context. CONCLUSION: Policymakers can learn from champions' experiences regarding barriers and enablers to implementation to adapt policy. Research is needed to understand what factors can promote the sustainability of champion-led policy implementation, and to explore best management practices to support their initiatives.

The effect of eligibility for antiretroviral therapy on body mass index and blood pressure in KwaZulu-Natal, South Africa.

We use a regression discontinuity design to estimate the causal effect of antiretroviral therapy (ART) eligibility according to national treatment guidelines of South Africa on two risk factors for cardiovascular disease, body mass index (BMI) and blood pressure. We combine survey data collected in 2010 in KwaZulu-Natal, South Africa, with clinical data on ART. We find that early ART eligibility significantly reduces systolic and diastolic blood pressure. We do not find any significant effects on BMI. The effect on blood pressure can be detected up to three years after becoming eligible for ART.
