Dlott CC, Pei X, Ittner J, et al. - Using a large patient database, the influence of net worth and race on total hip and knee arthroplasty (THA and TKA) utilization and outcomes of length of stay (LOS) and readmissions were explored. Researchers used StrataSphere data set, an aggregation of 49 health systems representing 209 hospitals for primary THA and TKA procedures performed in the calendar year 2019. Relationships between net worth and patients undergoing THA or TKA were evaluated by performing statistical analyses. The findings indicated that net worth is a strong driver of disparities in utilization of THA and TKA with lower utilization of these surgeries in patients with net worth < $10K and elevated utilization in patients with net worth from $100-250 and $250-500K.
