    Addressing the tensions and complexities involved in commissioning and undertaking implementation research in low- and middle-income countries
    (BMJ, 2018) Doherty, Tanya; Lewin, Simon; Kinney, Mary; Sanders, David; Mathews, Cathy; Daviaud, Emmanuelle; Goga, Ameena; Bhana, Arvin; Besada, Donela; Vanleeuw, Lieve; Loveday, Marian; Odendaal, Willem; Leon, Natalie
    Rapid scale-up of new policies and guidelines, in the context of weak health systems in low/middle-income countries (LMIC), has led to greater interest and funding for implementation research. Implementation research in LMICs is often commissioned by institutions from high-income countries but increasingly undertaken by LMIC-based research institutions. Commissioned implementation research to evaluate large-scale, donor-funded health interventions in LMICs may hold tensions with respect to the interests of the researchers, the commissioning agency, implementers and the country government. We propose key questions that could help researchers navigate and minimise the potential conflicts of commissioned implementation research in an LMIC setting.

    Applying a framework for assessing the health system challenges to scaling up mHealth in South Africa
    (BioMed Central, 2012) Leon, Natalie; Schneider, Helen; Daviaud, Emmanuelle
    Background: Mobile phone technology has demonstrated the potential to improve health service delivery, but there is little guidance to inform decisions about acquiring and implementing mHealth technology at scale in health systems. Using the case of community-based health services (CBS) in South Africa, we apply a framework to appraise the opportunities and challenges to effective implementation of mHealth at scale in health systems. Methods: A qualitative study reviewed the benefits and challenges of mHealth in community-based services in South Africa, through a combination of key informant interviews, site visits to local projects and document reviews. Using a framework adapted from three approaches to reviewing sustainable information and communication technology (ICT), the lessons from local experience and elsewhere formed the basis of a wider consideration of scale up challenges in South Africa. Results: Four key system dimensions were identified and assessed: government stewardship and the organisational, technological and financial systems. In South Africa, the opportunities for successful implementation of mHealth include the high prevalence of mobile phones, a supportive policy environment for eHealth, successful use of mHealth for CBS in a number of projects and a well-developed ICT industry. However there are weaknesses in other key health systems areas such as organisational culture and capacity for using health information for management, and the poor availability and use of ICT in primary health care. The technological challenges include the complexity of ensuring interoperability and integration of information systems and securing privacy of information. Finally, there are the challenges of sustainable financing required for large scale use of mobile phone technology in resource limited settings. Conclusion: Against a background of a health system with a weak ICT environment and limited implementation capacity, it remains uncertain that the potential benefits of mHealth for CBS would be retained with immediate large-scale implementation. Applying a health systems framework facilitated a systematic appraisal of potential challenges to scaling up mHealth for CBS in South Africa and may be useful for policy and practice decision-making in other low- and middle-income settings.

    Costs of implementing integrated community case management (iCCM) in six African countries: implications for sustainability
    (Edinburgh University Global Health Society, 2017) Daviaud, Emmanuelle; Besada, Donela; Leon, Natalie; Rohde, Sarah; Sanders, David; Oliphant, Nicholas; Doherty, Tanya
    BACKGROUND Sub–Saharan Africa still reports the highest rates of under– five mortality. Low cost, high impact interventions exist, however poor access remains a challenge. Integrated community case management (iCCM) was introduced to improve access to essential services for children 2–59 months through diagnosis, treatment and referral services by community health workers for malaria, pneumonia and diarrhea. This paper presents the results of an economic analysis of iCCM implementation in regions supported by UNICEF in six countries and assesses country–level scale–up implications. The paper focuses on costs to provider (health system and donors) to inform planning and budgeting, and does not cover cost–effectiveness. METHODS The analysis combines annualised set–up costs and 1 year implementation costs to calculate incremental economic and financial costs per treatment from a provider perspective. Affordability is assessed by calculating the per capita financial cost of the program as a percentage of the public health expenditure per capita. Time and financial implications of a 30% increase in utilization were modeled. Country scale–up is modeled for all children under 5 in rural areas. RESULTS Utilization of iCCM services varied from 0.05 treatment/y/under– five in Ethiopia to over 1 in Niger. There were between 10 and 603 treatments/community health worker (CHW)/y. Consultation cost represented between 93% and 22% of economic costs per treatment influenced by the level of utilization. Weighted economic cost per treatment ranged from US$ 13 (2015 USD) in Ghana to US$ 2 in Malawi. CHWs spent from 1 to 9 hours a week on iCCM. A 30% increase in utilization would add up to 2 hours a week, but reduce cost per treatment (by 20% in countries with low utilization). Country scale up would amount to under US$ 0.8 per capita total population (US$ 0.06–US$0.74), between 0.5% and 2% of public health expenditure per capita but 8% in Niger. CONCLUSIONS iCCM addresses unmet needs and impacts on under 5 mortality. An economic cost of under US$ 1/capita/y represents a sound investment. Utilization remains low however, and strategies must be developed as a priority to improve demand. Continued donor support is required to sustain iCCM services and strengthen its integration within national health systems.

    Critical reflections on conducting qualitative health research during Covid-19: The lived experiences of a cohort of postgraduate students in a South African university
    (Sage journal, 2023-01-02) Githaiga, Jennifer Nyawira; Spath, Carmen; Sicwebu, Namhla; Perera, Shehani; Tolla, Tsidiso; Leon, Natalie
    COVID-19 ushered in public health guidelines restricting face-to-face contact and movement, and encouraging social distancing, all of which had implications for conducting field-based research during the pandemic. For qualitative researchers, this meant adapting conventional face-to-face methods and resorting to virtual variations of the same in adherence to stipulated COVID-19 health protocols. Virtual qualitative research introduced new concerns and logistical challenges. This paper presents critical reflections on experiences of conducting qualitative research during the pandemic, from the perspectives of a cohort of postgraduate fellows. A critical reflection framework was utilised to explore fellows experiences and meanings ascribed to their experiences. The research findings illustrate three overarching processes which, in turn, shaped ways of thinking, doing and being. First, explicating tacit assumptions about their anticipated research journeys and interrogating these. Second, shifts in power differentials demonstrated by role reversal between researchers and participants, and between fellows and supervisors as they re-negotiated their positionalities in virtual research spaces. Third, context specific sense-making, in which - narrative accounts support the notion of knowledge as a social construct. Our findings have important implications for qualitative research practice. Our study documents methodological nuances and social implications of conducting qualitative research during COVID-19 and in a-South African context. In addition, our study exemplifies the use of critical reflection in qualitative research practice in the specific context of postgraduate academic research. Further, our study illustrates how the use of technology shapes qualitative research protocol development, data collection and analysis phases.

    The role of 'hidden' community volunteers in community-based health service delivery platforms: examples from sub-Saharan Africa
    (Co-Action Publishing, 2015) Leon, Natalie; Sanders, David; Damme, Wim Van; Besada, Donela; Daviaud, Emmanuelle; Oliphant, Nicholas P.; Berzal, Rocio; Mason, John; Doherty, Tanya
    Community-based research on child survival in sub-Saharan Africa has focussed on the increased provision of curative health services by a formalised cadre of lay community health workers (CHWs), but we have identified a particular configuration, that deserves closer scrutiny. We identified a two-tiered CHW system, with the first tier being the lessor known or 'hidden' community/village level volunteers and the second tier being formal, paid CHWs, in Ethiopia, Mali, and Niger. Whilst the disease-focussed tasks of the formal CHW tier may be more amenable to classic epidemiological surveillance, we postulate that understanding the relationship between formalised CHWs and volunteer cadres, in terms of scope, location of practice and ratio to population, would be important for a comprehensive evaluation of child survival in these countries.We report on the findings from our joint qualitative and quantitative investigations, highlighting the need to recognise the 'hidden' contribution of volunteers. We need to better characterize the volunteers' interaction with community-based and primary care services and to better understand ways to improve the volunteer systems with the right type of investments. This is particularly important for considering the models for scale-up of CHWs in sub-Saharan Africa.
