    The Role of the Private Sector in the COVID-19 Pandemic: Experiences From Four Health Systems
    (Frontiers in Public Health, 2022) Wallace, L.J.; AgyepongI., I.; Nonvignon, J.; et al.
    As societies urbanize, their populations have become increasingly dependent on the private sector for essential services. The way the private sector responds to health emergencies such as the COVID-19 pandemic can determine the health and economic wellbeing of urban populations, an effect amplified for poorer communities. Here we present a qualitative document analysis of media reports and policy documents in four low resource settings-Bangladesh, Ghana, Nepal, Nigeria-between January and September 2020. The review focuses on two questions: (i) Who are the private sector actors who have engaged in the COVID-19 first wave response and what was their role?; and (ii) How have national and sub-national governments engaged in, and with, the private sector response and what have been the effects of these engagements? Three main roles of the private sector were identified in the review. (1) Providing resources to support the public health response. (2) Mitigating the financial impact of the pandemic on individuals and businesses. (3) Adjustment of services delivered by the private sector, within and beyond the health sector, to respond to pandemic-related business challenges and opportunities. The findings suggest that a combination of public-private partnerships, contracting, and regulation have been used by governments to influence private sector involvement. Government strategies to engage the private sector developed quickly, reflecting the importance of private services to populations. However, implementation of regulatory responses, especially in the health sector, has often been weak reflecting the difficulty governments have in ensuring affordable, quality private services. Lessons for future pandemics and other health emergencies include the need to ensure that essential non-pandemic health services in the government and non-government sector can continue despite elevated risks, surge capacity to minimize shortages of vital public health supplies is available, and plans are in place to ensure private workplaces remain safe and livelihoods protected.

    Strengths, disconnects and lessons in local and central governance of the response to the first wave of COVID-19 in Ghana
    (Ghana Medical Journal, 2022) Wallac, L.J.; Afun, N.E.E.; Nonvignon, J.; et al.
    Objectives: To explore governance, coordination and implementation actors, structures and processes, facilitators, and barriers within local government and between central and local government in Ghana’s COVID-19 response dur ing the first wave of the outbreak. Design: Cross-sectional single case study. Data collection involved a desk review of media, policy and administrative documents and key informant in-depth interviews. Setting: Two municipalities in the Greater Accra region of Ghana Participants: Local government decentralised decision makers and officials of decentralised departments. Interventions: None. Main Outcome Measures: None Results: Coordination between the national and local government involved the provision of directives, guidelines, training, and resources. Most of the emergency response structures at the municipal level were functional except for some Public Health Emergency Management Committees. Inadequate resources challenged all aspects of the re sponse. Coordination between local government and district health directorates in risk communication was poor. Dur ing the distribution of relief items, a biased selection process and a lack of a bottom-up approach in planning and implementation were common and undermined the ability to target the most vulnerable beneficiaries. Conclusions: Adequate financing and equipping of frontline health facilities and workers for surveillance, laboratory and case management activities, transparent criteria to ensure effective targeting and monitoring of the distribution of relief items, and a stronger bottom-up approach to the planning and implementation of interventions need to be given high priority in any response to health security threats such as COVID-19.

    Challenges to the delivery of clinical diabetes services in Ghana created by the COVID-19 pandemic
    (Journal of Health Services Research & Polic, 2023) Tagoe, E.T.; Nonvignon, J.; Meer, R.V.D.; Megiddo, I.; Godman, B.
    Objective: The barriers to delivering clinical non-communicable disease services in low- and middle-income countries have risen with the onset of COVID-19. Using Ghana as a case study, this article examines the changes COVID-19 has brought to diabetes service delivery and considers policy responses to deal with future such outbreaks. Methods: We conducted 18 interviews between November 2020 and February 2021 with health professionals and administrators from primary, secondary and tertiary facilities within the Ghana Health Service. The analysis was performed using deductive and inductive methods. Results: There were six general themes in interviewees’ responses: (1) COVID-19 had exacerbated the problems of high medicine and service costs and medicine shortages, (2) the pandemic had exacerbated problems of poor patient record keeping, (3) COVID-19 had reduced the availability of suitably trained health providers, (4) staff had become demoralized by management’s unwillingness to make innovative changes to cope with the pandemic, (5) COVID-19 led to a reor ganization of diabetes services, and (6) the country’s national health insurance scheme lacked flexibility in dealing with the pandemic. Conclusions: Access to resources is limited in LMICs. However, our study highlights practical policy responses that can improve health providers’ response to COVID-19 and future pandemics

    Assessing the impacts of COVID-19 vaccination programme’s timing and speed on health benefts, cost-efectiveness, and relative afordability in 27 African countries
    (BMC Medicine, 2023) Liu, Y.; Procter, S.R.; Nonvignon, J.; et al.
    Background The COVID-19 vaccine supply shortage in 2021 constrained roll-out efforts in Africa while populations experienced waves of epidemics. As supply improves, a key question is whether vaccination remains an impactful and cost-effective strategy given changes in the timing of implementation. Methods We assessed the impact of vaccination programme timing using an epidemiological and economic model. We fitted an age-specific dynamic transmission model to reported COVID-19 deaths in 27 African countries to approximate existing immunity resulting from infection before substantial vaccine roll-out. We then projected health outcomes (from symptomatic cases to overall disability-adjusted life years (DALYs) averted) for different programme start dates (01 January to 01 December 2021, n=12) and roll-out rates (slow, medium, fast; 275, 826, and 2066 doses/ million population-day, respectively) for viral vector and mRNA vaccines by the end of 2022. Roll-out rates used were derived from observed uptake trajectories in this region. Vaccination programmes were assumed to priorities those above 60 years before other adults. We collected data on vaccine delivery costs, calculated incremental cost-efectiveness ratios (ICERs) compared to no vaccine use, and compared these ICERs to GDP per capita. We additionally calculated a relative affordability measure of vaccination programmes to assess potential nonmarginal budget impacts. Results Vaccination programmes with early start dates yielded the most health benefits and lowest ICERs compared to those with late starts. While producing the most health benefits, fast vaccine roll-out did not always result in the lowest ICERs. The highest marginal effectiveness within vaccination programmes was found among older adults. High country income groups, high proportions of populations over 60 years or non-susceptible at the start of vaccination programmes are associated with low ICERs relative to GDP per capita. Most vaccination programmes with small ICERs relative to GDP per capita were also relatively affordable.Conclusion Although ICERs increased significantly as vaccination programmes were delayed, programmes starting late in 2021 may still generate low ICERs and manageable affordability measures. Looking forward, lower vaccine purchasing costs and vaccines with improved efficacies can help increase the economic value of COVID-19 vaccination programmes.
