Recently published results showed hospital factors and procedure-related factors have a role in readmission risk after total hip arthroplasty.
Researchers used a multilevel logistic regression analysis with a clustered data structure to investigate the risk of all-cause 30-day and 90-day readmission incorporating hospital, clinical and patient factors among 442,333 patients aged 65 years or older who had a primary total hip arthroplasty (THA).
Results showed 5.8% of patients were readmitted at 30 days and 10.5% of patients were readmitted at 90 days. Significant hospital factors included geographic census region, hospital procedure volume and nonprofit ownership. However, researchers noted variation in readmission rates were explained more with clinical factors vs. hospital factors. Researchers found patients had a 14% greater risk of readmission with the use of a perioperative transfusion and patients discharged home had a 28% lower risk of readmission. Other significant risk factors included surgeon volume and length of stay. Researchers noted dislocation (5.9%), deep infection (5.1%), wound infection (4.8%), periprosthetic fracture (4.4%) and hematoma (3.4%) were the top five most frequently reported primary reasons for 30-day readmission in THA. – by Casey Tingle
