RESUMEN
BACKGROUND: Regional anesthesia techniques offer many benefits for total joint arthroplasty (TJA) patients. However, they require personnel and equipment resources, as well as valuable operating room (OR) time. A block room offers a dedicated environment to perform regional anesthesia procedures while potentially offsetting costs. METHODS: The goal of this prospective quality improvement study was to develop a business case for implementation of a regional anesthesia block room and to demonstrate the cost-effectiveness of this program in decreasing OR time for TJA. All elective TJA patients presenting between January 2019 and March 2020 were included in our analysis. RESULTS: Our detailed business plan was approved by the hospital leadership. 561 patients in the preintervention group and 432 in the postintervention group were included for data analysis. Mean total OR time per surgical case decreased from 166 to 143 min for a difference of 23 min (95% CI 17 to 29). Similarly, anesthesia controlled OR time decreased from 46 min to 26 min for a difference of 20 min (95% CI 17 to 22). The block room resulted in an additional primary TJA case per daily OR list. The percentage of TJA patients receiving a peripheral nerve block increased from 63.1% to 87.0% (p<0.001). No safety events or block room associated OR delays were observed. CONCLUSION: Implementing a regional anesthesia block room required a comprehensive business plan for securing the necessary resources to support the program. The regional anesthesia block room is a cost-effective method to improve patient care and OR efficiency.
