Understanding the impact of the COVID­19 pandemic on healthcare services for adults during three waves of COVID­19 infections: A South African private sector experience.

BACKGROUND: Since the onset of the COVID­19 pandemic, healthcare resources have been repurposed to focus on COVID­19. Resource reallocation and restrictions to movement that affected general access to care may have inadvertently resulted in undue disruptions in the continuum of care for patients requiring non-COVID­19 healthcare services. OBJECTIVES: To describe the change in pattern of health service use in the South African (SA) private sector. METHODS: We conducted a retrospective study of a nationwide cohort of privately insured individuals. An analysis of claims data was performed for non-COVID­19 related healthcare services provided from April 2020 to December 2020 (year 1 of COVID­19) and April 2021 to December 2021 (year 2 of COVID­19) relative to the same period in 2019 prior to the COVID­19 pandemic in SA. Over and above plotting the monthly trends, we tested for statistical significance of the changes using a Wilcoxon test given the non-normality of all the outcomes. RESULTS: Between April and December 2020, relative to the same period in 2021, and also relative to the same period in 2019, we found a 31.9% (p<0.01) and a 16.6% (p<0.01) reduction in emergency room visits, respectively; a 35.9% (p<0.01) and 20.5% (p<0.01) reduction in medical hospital admissions; a 27.4% (p=0.01) and 13.0% (p=0.03) reduction in surgical hospital admissions; a 14.5% (p<0.01) and 4.1% (p=0.16) reduction in face-to-face general practitioner consultations for chronic members; a 24.9% (p=0.06) and 5.2% (p=0.54) reduction in mammography for female members; a 23.4% (p=0.03) and 10.8% (p=0.09) reduction in Pap smear screenings for female members; a 16.5% (p=0.08) and 12.1% (p=0.27) reduction in colorectal cancer registrations and an 18.2% (p=0.08) and 8.9% (p=0.07) decrease in all oncology diagnoses. Uptake of telehealth services throughout the healthcare delivery system increased by 5 708% in 2020 compared with 2019, and 36.1% for 2021 compared with 2020. CONCLUSION: A significant reduction in emergency room visits, hospital admissions and utilisation of primary care services was observed since the start of the pandemic. Further research is required to understand if there are long-term consequences of delayed care. An increase in the use of digital consultations was observed. Research on their acceptability and effectiveness may open new modalities of care, which may have cost- and time-saving benefits.

South Africa's COVID-19 Tracing Database: Risks and rewards of which doctors should be aware.

In response to the COVID-19 pandemic, South Africa (SA) has established a Tracing Database, collecting both aggregated and individualised mobility and locational data on COVID-19 cases and their contacts. There are compelling public health reasons for this development, since the database has the potential to assist with policy formulation and with contact tracing. While potentially demonstrating the rapid facilitation through technology of an important public service, the Tracing Database does, however, infringe immediately upon constitutional rights to privacy and heightens the implications of ethical choices facing medical professionals. The medical community should be aware of this surveillance innovation and the risks and rewards it raises. To deal with some of these risks, including the potential for temporary rights- infringing measures to become permanent, there are significant safeguards designed into the Tracing Database, including a strict duration requirement and reporting to a designated judge. African states including SA should monitor this form of contact tracing closely, and also encourage knowledge-sharing among cross-sectoral interventions such as the Tracing Database in responding to the COVID-19 pandemic.
