AbstractIntroductionCoronavirus disease 2019 (COVID‐19) is associated with poor outcomes in sickle cell disease (SCD) patients. However, there is a paucity of data comparing hemoglobin (Hb) genotypes in SCD and infection outcomes.MethodsThe National Inpatient Sample was used to identify the record of hospitalizations with COVID‐19 and SCD in 2020 using the International Classification of Disease, Tenth Revision codes. Study outcomes (invasive mechanical ventilation, extracorporeal membrane oxygenation, shock, vasopressor use, measures of resource utilization, and in‐hospital mortality) were compared between hemoglobin SS, SC, and S‐beta thalassemia (Sβ).ResultsOf the 102 975 COVID‐19 hospitalizations with SCD, 87.26% had HbSS, 7.16% had HbSC, and 5.58% had HbSβ. Younger patients were more likely to have HbSS, while older patients were likely to have HbSC and HbSβ. HbSS was more frequent with Blacks, while HbSβ was more prevalent with Whites and Hispanics. Though measures of resource utilization were higher in HbSS, there was no significant difference in in‐hospital outcomes between the three genotypes.ConclusionThere is no difference in COVID‐19 outcomes among Hb genotypes in SCD. Further studies are needed to explore the reasons for this observation.
