dc.description.abstractBackground: Blood usage and collections were impacted throughout 2020 both by the severity of the COVID-19 pandemic as well as public health decisions affecting hospital operations. We sought to understand the longer-term effects of the pandemic on blood usage via changes in case volume and clinical intensity as well as whether the blood needs of COVID-19-positive patients differed from other transfused patients. Study design and methods: A single-center retrospective study of blood use in 2020 as compared to 2014–2019 was conducted at a tertiary care center. Statistical analysis was performed in an R-based workflow. p values are reported using two-sided t-tests for total hospital blood usage and using Mann–Whitney U tests for comparisons of patient blood usage. Results: Mean monthly red cell usage in 2020 decreased by 11.2% (p =.003), plasma usage decreased by 23.8%, (p <.001) platelet usage decreased by 11.4% (p <.001), and monthly cryoprecipitate use increased by 18% (p =.03). A linear regression model predicted significant associations between total blood usage and the year, number of Medicare eligible discharges, and Case Mix Index. COVID-19-positive patients requiring at least one blood product did not use significantly different amounts of red cells, plasma, or platelets from all other transfused patients. Conclusions: Year 2020 began with decreased blood usage that was normalized by late spring. Reassuringly, transfused COVID-19-positive patients in general and those requiring ICU level care do not use significantly increased amounts of blood as compared to similar transfused hospital patients. © 2021 AABBen_US
