Among patients who underwent total joint arthroplasty, readmission rates were predicted by female gender, American Society of Anesthesiologists class and duration of procedure, according to study results.
Researchers retrospectively assessed 30-day readmission rates among patients who underwent primary total hip arthroplasty (THA) and total knee arthroplasty (TKA) between 2007 and 2012. Overall, 1,078 primary total joint arthroplasty patients were included, of which 38 were identified as readmissions and 129 were selected as control patients.
Although age, marital status, race and insurance status were not associated with readmissions, the researchers found female gender was associated with readmission rates.
A logistic regression model showed, along with female gender, duration of the procedure and high ASA class were significantly associated with readmission, according to the researchers.
Patients were most often readmitted within the first week after discharge, and the most common readmission diagnosis was gastrointestinal issues, followed by surgical site infections and cardiopulmonary issues.
