Evaluation of a Preoperative Optimization Protocol for Primary Hip and Knee Arthroplasty Patients.

Background: Preoperative optimization of risk factors has been suggested as a strategy to improve the value of total joint arthroplasty (TJA) care. We assessed the implementation of a TJA preoperative optimization protocol and its impact on length of hospital stay, discharge destination, 90-day readmissions, and hospital direct variable costs.

Methods: This retrospective cohort study included adults undergoing primary elective TJA from 07/2015-09/2016 at an urban tertiary care hospital.
