RA Associated With Higher 90-Day Hospital Readmission Rates Compared to OA After Hip or Knee Arthroplasty Save

Using administrative claims data, Doctor Jas Singh and colleagues examined readmission rates after hip or knee replacement surgery. RA patients had a higher rate of readmission (8.5% vs 6.7%) compared to OA. RA patients were more likely to be readmitted for prosthetic infections (10.2%) and sepsis (10.2%) while OA patients had lower rates of prosthetic infection (5.7%) and post operative infection (5.1%).  Surprisingly, readmissions increased for RA patients yearly between 2009 – 2011. It was unclear why this trend was seen in RA.
