1. Background and rationale. According to the latest Canadian Census, seniors aged 65 or over have increased in number by 609,810 from 13.7% of the population in 2006 to 4,945,060, or 14.8% in 2011. In Ontario, in 2001, there were 8,000 total hip replacements (THR) and 11,000 total knee replacements (TKR); in 2016, the projection is 20,000 THR and 54,000 TKR, assuming age-specific rates remain the same(1). At The Ottawa Hospital (TOH), we have already witnessed the pressure on bed management due to the increasing case volume. As a solution, we have successfully organized early discharges (EDc), on the same day, in select patients after unicompartment arthroplasty in order to reduce the length of stay (LOS)(2). Since then, we have discharged select major joint replacement patients on the same day or after overnight stay on multimodal analgesia.
