ABSTRACT
The objective of this study was to determine if implementation of a simplified care pathway for total knee arthroplasty (TKA) would affect outcomes of total hip arthroplasty (THA) patients in the same health care system. Data were collected from a total of 5,095 consecutive THA patients in the year before and 2 years after implementation of the care pathway for TKA patients. Postimplementation increases were observed in both early activity (p < 0.0001) and continuous urinary catheter avoidance (p < 0.0001) among THA patients. These improvements in protocol adherence were associated with decreased complications (p < 0.0001), fewer 30-day readmissions (p < 0.0019), and decreased hospital length of stay (p < 0.0001). Based on these results, the implementation of a simplified care pathway for TKA patients can also improve outcomes for THA patients in the same health care system.

Care pathways for total knee arthroplasty (TKA) demonstrate improved quality and utilization outcomes. Standardizing these processes over large systems is difficult due to the variability of practice patterns and the complexity of multistep pathways. A simplified approach to this process focusing on early activity and avoidance of continuous urinary catheters was performed to overcome these perceived barriers for implementing a system-wide care pathway. Data were collected from a total of 6,154 consecutive patients during the time period of 1 year before and 1 year after implementation of a pathway focusing on two key drivers: early activity and continuous urinary catheter avoidance. Patients included were adults admitted for elective primary TKA. A composite score was calculated based on the successful completion of the two key drivers. Outcome measures were tracked before and after implementation. Following implementation of a simplified TKA care pathway, there was a significant increase in the composite score with increases attributable to both increased early activity (p < 0.0001) and continuous urinary catheter avoidance (p < 0.0001). This improvement in composite score was associated with a significant decrease in hospital length of stay (HLOS) (p < 0.0001), costs (p < 0.0001), complications (p < 0.0001), and 30-day readmissions (p < 0.0106). A fixed-effect model analysis demonstrated early activity was associated with improvements in HLOS (p < 0.0001), complications (p = 0.0240), and 30-day readmissions (p = 0.0046). Avoidance of a continuous urinary catheter was associated with improvements in HLOS (p = 0.0001), costs (p < 0.0001), complications (p = 0.0006), and 30-day readmissions (p = 0.0008). A simplified care pathway for TKA focusing on early activity and continuous urinary catheter avoidance is associated with improved complications, costs, HLOS, and 30-day readmissions.
