Economic impact of anaesthesia methods used in hand surgery: Global costs and operating room's throughput.

PURPOSE: Recently, local anaesthesia has become popular among hand surgeons. We hypothesized that using the "wide awake local anaesthesia no tourniquet" (WALANT) approach would result in lower global costs and in an increase in the operating room (OR)'s efficiency.

METHODS

All cases of carpal tunnel (CTR) and trigger finger releases (TFR) performed over 2016 and 2017 were divided into four groups, following which the anaesthesia method was used. Total OR occupation time, surgical time and the "all but surgery" time were analysed. A common minimum bill per anaesthesia was generated.

RESULTS

WALANT or local anaesthesia and tourniquet increase the OR's throughput by having shorter operation room occupation times than other methods (17.5-33%). Costs of the two procedures are reduced by 21-31% when using local anaesthesia methods.

CONCLUSION

Preferring those techniques for CTR and TFR has a notable beneficial impact on the costs and on the OR's efficiency. This effect is more evident on short surgical procedures. LOE: Level of evidence III, economic analysis.
