An Economic Analysis of MAC Versus WALANT: A Trigger Finger Release Surgery Case Study

Abstract

Background: There has been recent interest in wide awake hand surgery, also referred to as "wide awake local anesthesia with no tourniquet" (WALANT) surgery. Using a model of single trigger finger release (TFR) surgery, a hypothesis was made that WALANT would result in decreased hospital time and cost than patients receiving sedation with monitored anesthetic care (MAC).

Methods: Consecutive cases of single TFR surgery with MAC were compared with WALANT. All surgeries were performed in the same manner, at the same facility, and by the same surgeon. Total operating room (OR) time, surgical time, recovery time, and anesthesia costs were analyzed.

Results: There were 78 patients: 31 MAC and 47 WALANT. The MAC group averaged 27.2 minutes of OR time; the WALANT group averaged 25.2 minutes. The MAC group surgical time was 10.2 minutes versus WALANT of 10.4 minutes. Post-operatively, the MAC group averaged 72.3 minutes in the recovery room compared with WALANT group of 30.2 minutes. Each case performed under MAC had a minimum of excess charges from anesthesia of approximately $105.

Conclusions: Patients undergoing single TFR surgery under WALANT trended toward less time in the OR, had similar surgical times, and spent significantly less time in the recovery room, compared with MAC, thereby resulting in less indirect costs. Each MAC case also had minimum direct excess anesthesia charges of $105, which knowingly underestimates overall charges as it excludes material and fixed costs associated with the delivery of anesthesia. Avoiding sedation for high-volume procedures such as TFR may result in significant systemic savings to payers, and in the future with bundling and episode-based payments can become increasingly important to patients, facilities, and surgeons.
