Objective To explore the effect of PDCA circulation on the effective utilization of the disposable articles in the operating room.Methods 9,362 aseptic articles for 446 operations in the departments of general surgery and hepatobiliary surgery during January to May 2012 were put in the pre-experiment group,in which PDCA circulation was not used.Another 11,973 articles for 501 operations in the same departments during June to November 2012 were set as the post-experiment group,in which PDCA circulation was used.The two groups were compared in terms of the effective utilization rate and the degree of doctor’s satisfaction with the nurses in the operation room.Result After the implementation of PDCA circulation,the effective utilization rate and the degree of doctor’s satisfaction were both significantly higher than before the implementation(both P<0.05).Conclusion PDCA circulation for the management of sterile disposable articles in the operation room may effectively improve the utilization rate of disposable articles, reduce wasting of articles and safe resources.
