For the study, researchers assessed more than 1.4 million Medicare beneficiaries who underwent primary total hip arthroplasty and more than 348,000 patients who underwent revision total hip arthroplasty.
Between 1991 and 2008, mean hospital LOS decreased from 9.1 days in 1991-1992 to 3.7 days in 2007-2008 for primary total hip arthroplasty. Meanwhile, 30-day all-cause readmission increased from 5.9 percent to 8.5 percent. Similar trends were observed for revision total hip arthroplasty in regard to hospital LOS and hospital readmission.
