The Increased Total Cost Associated With Post-Operative Drains in Total Hip and Knee Arthroplasty

In a consecutive series of 536 unilateral primary total hip arthroplasties (THAs) and 598 unilateral primary total knee arthroplasties (TKAs), the use of a post-operative drain was associated with $538 additional cost per THA, and $455 for TKA. The use of a drain increased hospital length of stay (LOS) for THA, but not for TKA. In both groups, the use of a drain increased estimated blood loss (EBL) and increased the amount of allogeneic blood transfused. Over the 10-week period, drain use was associated with a total cost of $432,972 for our institution. Data from this study would favor a selective approach to the use of drains in primary joint arthroplasties. (C) 2014 Elsevier Inc. All rights reserved.
