Multi-country collaborative citizen science projects to co-design cardiovascular disease prevention strategies and advocacy: findings from Ethiopia, Malawi, Rwanda, and South Africa

BACKGROUND

Cardiovascular diseases (CVD) were responsible for 20.5 million annual deaths globally in 2021, with a disproportionally high burden in sub-Saharan Africa (SSA). There is growing evidence of the use of citizen science and co-design approaches in developing interventions in different fields, but less so in the context of CVD prevention interventions in SSA. This paper reports on the collaborative multi-country project that employed citizen science and a co-design approach to (i) explore CVD risk perceptions, (ii) develop tailored prevention strategies, and (iii) support advocacy in different low-income settings in SSA.

METHODS

This is a participatory citizen science study with a co-design component. Data was collected from 205 participants aged 18 to 75 years in rural and urban communities in Malawi, Ethiopia and Rwanda, and urban South Africa. Fifty-one trained citizen scientists used a mobile app-based (EpiCollect) semi-structured survey questionnaire to collect data on CVD risk perceptions from participants purposively selected from two communities per country. Data collected per community included 100-150 photographs and 150-240 voice recordings on CVD risk perceptions, communication and health-seeking intentions. Thematic and comparative analysis were undertaken with the citizen scientists and the results were used to support citizen scientists-led stakeholder advocacy workshops. Findings are presented using bubble graphs based on weighted proportions of key risk factors indicated.

RESULTS

Nearly three in every five of the participants interviewed reported having a relative with CVD. The main perceived causes of CVD in all communities were substance use, food-related factors, and litter, followed by physical inactivity, emotional factors, poverty, crime, and violence. The perceived positive factors for cardiovascular health were nutrition, physical activity, green space, and clean/peaceful communities. Multi-level stakeholders (45-84 persons/country) including key decision makers participated in advocacy workshops and supported the identification and prioritization of community-specific CVD prevention strategies and implementation actions. Citizen science-informed CVD risk screening and referral to care interventions were piloted in six communities in three countries with about 4795 adults screened and those at risk referred for care. Health sector stakeholders indicated their support for utilising a citizen-engaged approach in national NCDs prevention programmes. The citizen scientists were excited by the opportunity to lead research and advocacy.

CONCLUSION

The collaborative engagement, participatory learning, and co-designing activities enhanced active engagement between citizen scientists, researchers, and stakeholders. This, in turn, provided context-specific insights on CVD prevention in the different SSA settings.

Developing, implementing, and monitoring tailored strategies for integrated knowledge translation in five sub-Saharan African countries

BACKGROUND

Integrated knowledge translation (IKT) through strategic, continuous engagement with decision-makers represents an approach to bridge research, policy and practice. The Collaboration for Evidence-based Healthcare and Public Health in Africa (CEBHA +), comprising research institutions in Ethiopia, Malawi, Rwanda, South Africa, Uganda and Germany, developed and implemented tailored IKT strategies as part of its multifaceted research on prevention and care of non-communicable diseases and road traffic injuries. The objective of this article is to describe the CEBHA + IKT approach and report on the development, implementation and monitoring of site-specific IKT strategies.

METHODS

We draw on findings derived from the mixed method IKT evaluation (conducted in 2020-2021), and undertook document analyses and a reflective survey among IKT implementers. Quantitative data were analysed descriptively and qualitative data were analysed using content analysis. The authors used the TIDieR checklist to report results in a structured manner.

RESULTS

Preliminary IKT evaluation data (33 interviews with researchers and stakeholders from policy and practice, and 31 survey responses), 49 documents, and eight responses to the reflective survey informed this article. In each of the five African CEBHA + countries, a site-specific IKT strategy guided IKT implementation, tailored to the respective national context, engagement aims, research tasks, and individuals involved. IKT implementers undertook a variety of IKT activities at varying levels of engagement that targeted a broad range of decision-makers and other stakeholders, particularly during project planning, data interpretation, and output dissemination. Throughout the project, the IKT teams continued to tailor IKT strategies informally and modified the IKT approach by responding to ad hoc engagements and involving non-governmental organisations, universities, and communities. Challenges to using systematic, formalised IKT strategies arose in particular with respect to the demand on time and resources, leading to the modification of monitoring processes.

CONCLUSION

Tailoring of the CEBHA + IKT approach led to the inclusion of some atypical IKT partners and to greater responsiveness to unexpected opportunities for decision-maker engagement. Benefits of using systematic IKT strategies included clarity on engagement aims, balancing of existing and new strategic partnerships, and an enhanced understanding of research context, including site-specific structures for evidence-informed decision-making.

Implementing and Evaluating Community Health Worker-Led Cardiovascular Disease Risk Screening Intervention in Sub-Saharan Africa Communities: A Participatory Implementation Research Protocol

The increasing burden of non-communicable diseases (NCDs), particularly cardiovascular diseases (CVD) in low- and middle-income countries (LMICs) poses a considerable threat to public health. Community-driven CVD risk screening, referral and follow-up of those at high CVDs risk is essential to supporting early identification, treatment and secondary prevention of cardiovascular events such as stroke and myocardial infarction. This protocol describes a multi-country study that aims to implement and evaluate a community health worker (CHW)-led CVD risk screening programme to enhance referral linkages within the local primary care systems in sub-Saharan Africa (SSA), using a participatory implementation science approach. The study builds upon a prior community-driven multicentre study conducted by the Collaboration for Evidence-based Health Care and Public Health in Africa (CEBHA+). This is a participatory implementation research. The study will leverage on the CVD risk citizen science pilot studies conducted in the four selected CEBHA+ project countries (viz. Ethiopia, Rwanda, Malawi, and South Africa). Through planned engagements with communities and health system stakeholders, CHWs and lay health worker volunteers will be recruited and trained to screen and identify persons that are at high risk of CVD, provide referral services, and follow-up at designated community health clinics. In each country, we will use a multi-stage random sampling to select and then screen 1000 study participants aged 35-70 years from two communities (one rural and one urban). Screening will be done using a simple validated non-laboratory-based CVD risk assessment mobile application. The RE-AIM model will be used in evaluating the project implementation outcomes, including reach, fidelity, adoption and perceived effectiveness. Developing the capacities of CHWs and lay health worker volunteers in SSA to support population-based, non-invasive population-based CVD risk prevention has the potential to impact on early identification, treatment and secondary prevention of CVDs in often under-resourced communities. Using a participatory research approach to implementing mobile phone-based CHW-led CVD risk screening, referral and follow-up in SSA will provide the evidence needed to determine the effectiveness of CVD risk screening and the potential for scaling up in the wider region.

Integrated Knowledge Translation in Non-Communicable Disease Research in Sub-Saharan Africa: A Comparison of Systematic and Ad Hoc Stakeholder Engagement

Background

Low- and middle-income countries (LMICs) are currently experiencing an increasing prevalence of non-communicable diseases (NCDs). To address this as well as other health challenges, Integrated Knowledge Translation (IKT) approaches to build mutually beneficial relationships between researchers and decision-makers can concurrently inform research as well as enhance evidence use in policy and practice. The Collaboration for Evidence-Based Healthcare and Public Health in Africa (CEBHA+) is a research consortium which conducts research on NCDs and uses an IKT approach to facilitate the uptake of this research in five African countries: Ethiopia, Uganda, Rwanda, Malawi, and South Africa. Tailored IKT strategies were designed and implemented to plan and guide stakeholder engagement. This systematic approach contrasts with more commonly used ad hoc approaches to stakeholder engagement.

Methods

In this article, we explore the experiences of researchers engaged in the CEBHA+ IKT approach across the five African countries. Data sources included: 1) an informal document review of CEBHA+ country-specific IKT strategies, IKT team meeting minutes and activity reports, and 2) a semi-structured survey of IKT implementers to elicit country-specific experiences on actual implementation and adaptation of the IKT strategies. Results were collated and contrasted across all CEBHA+ countries with a focus on systematic versus ad hoc approaches to engagement.

Results

South Africa, Malawi and Ethiopia country teams indicated that their engagements benefited from a systematic IKT strategy. This was especially the case in the early stages of the project as it allowed focused and intentional engagement. However, ad hoc engagement was still required as new professional relationships developed, and contextual circumstances - including the SARS-CoV-2 pandemic - required responsive engagement with decision-makers and other stakeholders. In Rwanda and Uganda, continuous systematic engagement was found to bolster ownership of the research at both community and national levels.

Conclusion

Political and health climates are constantly shifting with a need to maintain flexibility in how IKT strategies are implemented. While strategic IKT can benefit from deliberate planning and stakeholder engagement, there is value in remaining flexible to respond to the needs of stakeholders and contextual circumstances. This paper highlights how IKT implementers in the five African CEBHA+ countries responded to this challenge.
