Abstract
Our study aims to investigate the safety and efficiency of the Codonics Safe Label System (SLS) in a prospective simulation study. Three sets of simulated experiments involving 82 anesthetists were carried out on patient simulator mannequins. The primary outcome assessed through the simulated experiments was the effectiveness of the SLS in avoiding vial swap errors. Secondary outcomes analyzed included the efficacy of the SLS in preventing syringe swap and the difference in time taken to prepare standardized drugs as compared with conventional methods. The SLS was associated with a significant reduction in all 4 stages of vial swap error. The incidence of wrong ampoule breakage was significantly lower in the SLS group compared with the conventional group (12.1% versus 38.5%, P = 0.007). The number of staff who drew the wrong ampoule was similarly lower in the SLS group compared with the conventional group (4.9% versus 33.3%, P = 0.001). The proportions of staff who eventually wrongly labeled the loaded syringe were 0% in the SLS group and 17.9% in the conventional group (P = 0.005).Drug preparation time was longer for the SLS group than for the conventional group (239.6 ± 45.9 versus 160.3 ± 46.5 seconds, P < 0.001).There was no significant difference in the incidence of syringe swap with the use of the SLS. The use of the SLS is effective in reducing vial swap error, but not syringe swap errors, and is associated with increased time taken for anesthetic drug preparation.
