Abstract
Total hip and knee arthroplasty are two of the most successful procedures in orthopaedics. However, with the increasing demand, estimated future costs for these procedures are enormous. Recent data suggests that post-discharge care may account for up to 35% of total episode payments. Yet, little is known about targets that can help improve quality and reduce cost. This retrospective study shows that an ASA score of ≥3 is associated with a 2.9 times (p = 0.0082) greater risk of re-admission in total joint arthroplasty patients. The current literature corroborates this finding by demonstrating an increase risk of post-operative complications in patients with an ASA of ≥3. Therefore, the ASA score is a potential target for interventions designed to increase quality and lower cost in arthroplasty patients.
