There is currently wide variation in the use and cost of post acute care following total joint arthroplasty. Additionally the optimum setting to which patients should be discharged after surgery is controversial. Discharge patterns following joint replacement vary widely between physicians at our institution, however, only weak correlations were found between the cost of discharge and length of stay or readmission rates. The inter-physician variance in discharge cost did not correlate to a difference in quality, as measured by length of stay and readmission rates, but does imply there is significant opportunity to modify physician discharge practices without impacting patient outcomes and the quality of care.
