title: Predictive risk factors for 30-day readmissions following primary total joint arthroplasty and modification of patient management.
abstract: The Centers for Medicare and Medicaid have begun to publically publish statistics on readmissions following primary total hip (THA) and total knee arthroplasty (TKA). Our study retrospectively assesses 30-day readmissions rates following THA and TKA, performed by a single surgeon at a tertiary care medical center between 2007 and 2012. Results of a univariate analysis and logistic regression model indicated female gender, high ASA class, and increased operative time to be significantly associated with higher rates of readmission (OR 4.646, OR 1.257, and OR 5.323, respectively). Readmissions most often occurred within the first week of patient discharge. Surgical complications and gastrointestinal discomfort were the most common causes for readmission. Using readmission risk we can stratify patients into tiered critical care pathways to reduce readmissions.
