A 'swing room' model based on regional anesthesia reduces turnover time and increases case throughput.

摘要

PURPOSE: Our centre recently implemented a new ambulatory care model featuring two alternate regional anesthesia "swing" operating rooms (RA-SRs) managed by a single anesthesiologist. We hypothesized that this model would be associated with decreased turnover times and improved recovery profiles when compared with a traditional model with a single operating room using general anesthesia. METHODS: We conducted a retrospective cohort study of 164 patients scheduled for hand and wrist surgery who were treated in the RA-SRs under brachial plexus blockade, and we compared the findings with a matched historical control group of patients who underwent general anesthesia in a single operating room (GA-OR). The primary endpoint was room turnover time. Secondary endpoints included home discharge time, postoperative interventions for nausea and pain, and number of cases possible per eight-hour day. RESULTS: Patients in the RA-SR group had faster turnover times than patients in the GA-OR group (median [interquartile range]: 15 min [8-22] vs 54 min [49-61], respectively) as well as faster home discharge times (28 min [20-46] vs 156 min [118-215], respectively) (P < 0.0001). In the RA-SR group, postoperative antiemetics were used in 3/164 patients (2%) vs 28/164 (17%) in the GA-OR group (P < 0.0001), and opioids were used in 1/164 (0.6%) vs 132/164 (80%), respectively (P < 0.0001). The median number of daily cases possible in the RA-SR group was 56% greater than in the GA-OR group (8.4 [7.5-9.4] vs 5.4 [5.1-5.8], respectively; P < 0.0001). CONCLUSION: Compared with a traditional model using general anesthesia in a single operating room, the implementation of a model using regional anesthesia with two swing operating rooms was associated with reduced room turnover times, improved recovery profiles, and a higher case throughput.
