Avascular necrosis linked with increased risk of transfusion, readmission after THA
Recently published results showed patients who underwent total hip arthroplasty for avascular necrosis of the femoral head had an increased risk of transfusion up to 72 hours postoperatively and readmission up to 30 days after surgery.
Using the American College of Surgeon’s National Surgical Quality Improvement Program database, researchers matched 1,706 patients who underwent total hip arthroplasty (THA) for avascular necrosis to 1,706 patients undergoing THA for osteoarthritis or unspecified arthritis. Researchers compared the primary outcome measures of surgical complications, medical complications, readmission and reoperation within 30 days after surgery between the two cohorts.
Results showed a higher rate of medical complications among patients with avascular necrosis vs. patients without avascular necrosis. Researchers found bleeding transfusion, which was the most common medical complication, occurred at a significantly higher rate among patients with avascular necrosis.
Multivariate regression showed the odds of having a medical complication was independently increased by avascular necrosis alone. Researchers noted the odds of readmission following THA were doubled by avascular necrosis, despite comparable readmission rates between the groups. – by Casey Tingle
