Clin Rheumatol. 2019 Apr;38(4):1213-1216. doi: 10.1007/s10067-019-04434-3. Epub 2019 Jan 22.

Abstract

Little is known about the effect of gout on in-hospital complications and healthcare utilization after total hip arthroplasty (THA). We used the 1998-2014 U.S. National Inpatient Sample (NIS) to examine this question using cohort study design. Multivariable-adjusted Cox regression analyses included age, race, gender, underlying diagnosis, Deyo-Romano comorbidity index, insurance payer, and income. In adjusted analyses, we found that gout was associated with 9-20% higher healthcare utilization and 6% higher hazard of transfusion after primary THA. These findings can inform surgeons and patients of gout-associated complications post-THA.
