Maximising the efficiency of surveillance for COVID-19 in dialysis units in South Africa : the case for pooled testing

Abstract

The COVID-19 epidemic in South Africa (SA) is currently in a growth phase with high incidences in most major cities. Patients who are dependent on chronic renal dialysis care, including peritoneal dialysis and haemodialysis, are chronically unwell and usually have multiple comorbidities including hypertension, diabetes and cardiovascular disease. These comorbidities are known to increase the risk of adverse outcomes for COVID-19, including hospitalisation with high care or intensive care admission, and/ or death. Haemodialysis patients throughout the country require facility-based support three times a week, and a typical dialysis visit is ~4 hours.
