Effects of COVID-19 on paediatric cardiac centres in low-income and middle-income countries: A mixed-methods study

Objectives The aim of this study was to understand the effects of the COVID-19 pandemic on paediatric cardiac services in critical access centres in low-income and middle-income countries. Design A mixed-methods approach was used. Setting Critical access sites that participate in the International Quality Improvement Collaborative (IQIC) for congenital heart disease (CHD) were identified. Participants Eight IQIC sites in low-income and middle-income countries agreed to participate. Outcome measures Differences in volume and casemix before and during the pandemic were identified, and semistructured interviews were conducted with programme representatives and analysed by two individuals using NVivo software. The qualitative component of this study contributed to a better understanding of the centres' experiences and to identify themes that were common across centres. Results In aggregate, among the seven critical access sites that reported data in both 2019 and 2020, there was a 20% reduction in case volume, though the reduction varied among programmes. Qualitative analysis identified a universal impact for all programmes related to Access to Care/Clinical Services, Financial Stability and Professional/Personal Issues for healthcare providers. Conclusions Our study identified and quantified a significant impact of the COVID-19 pandemic on critical access to CHD surgery in low-income and middle-income countries, as well as a significant adverse impact on both the skilled workforce needed to treat CHD and on the institutions in which care is delivered. These findings suggest that the COVID-19 pandemic has been a major threat to access to care for children with CHD in resource-constrained environments and that this effect may be long-lasting beyond the global emergency. Efforts are needed to preserve vulnerable CHD programmes even during unprecedented pandemic situations.
