The study analyzed data from the US Department of Veterans Affairs healthcare databases to estimate the burden of Post-Acute Sequelae of SARS-CoV-2 infection (PASC), finding approximately 73.43 PASC cases per 1000 persons at 6 months. The burden of PASC varied by demographic groups and baseline health status, with more severe acute infection leading to higher burden. The study highlights the substantial burden of PASC and the importance of considering different population groups when planning healthcare strategies.
The Post-Acute Sequelae of SARS-CoV-2 infection (PASC) have been characterized; however, the burden of PASC remains unknown. Here we used the healthcare databases of the US Department of Veterans Affairs to build a cohort of 181,384 people with COVID-19 and 4,397,509 non-infected controls and estimated that burden of PASC-defined as the presence of at least one sequela in excess of non-infected controls-was 73.43 (72.10, 74.72) per 1000 persons at 6 months. Burdens of individual sequelae varied by demographic groups (age, race, and sex) but were consistently higher in people with poorer baseline health and in those with more severe acute infection. In sum, the burden of PASC is substantial; PASC is non-monolithic with sequelae that are differentially expressed in various population groups. Collectively, our results may be useful in informing health systems capacity planning and care strategies of people with PASC.
