BackgroundThis article evaluates the predictive accuracy of the CareMOSAIC Risk Assessment for discharge disposition in Medicare patients undergoing total joint arthroplasty.MethodsRetrospectively collected data from a single institution on 499 consecutive Medicare patients who underwent primary total hip arthroplasty or total knee arthroplasty were reviewed. The CareMOSAIC Risk Assessment was completed by each patient during the preoperative period. The CareMOSAIC Risk Assessment scores were calculated via the CareMOSAIC software, and the scores indicate a risk category for each patient as it relates to post–acute care discharge needs.ResultsThe CareMOSAIC Risk Assessment with a binary logistic regression area under the receiver operating characteristic curve of 0.798 appears to be a reliable tool for predicting discharge disposition. The assessment had a positive predictive value of 90.0% and negative predictive value of 76.3% for discharge disposition.ConclusionsThe CareMOSAIC Risk Assessment effectively predicts the discharge disposition for Medicare patients undergoing total hip or total knee arthroplasty.
