Patient health, discharge disposition correlated with return to hospital after TKA

August 25, 2016

Among patients who underwent primary total knee arthroplasty, return to hospital events correlated with the health of the patient and initial discharge disposition, but not patient length of stay, according to results.

Researchers identified 995 patients (65% were women) who underwent total knee arthroplasty (TKA) between January 2011 and July 2013. Using the Wilcoxon signed rank test for nonparametric variables and Fisher exact test for categorical variables, researchers compared length of stay, Charlson comorbidity score, history of deep vein thrombosis (DVT), discharge disposition and post-discharge emergency department events for patients with a length of hospital stay of 2 days or less vs. patients with a hospital stay of 3 days or more.
