目的明确六西格玛对于防范医疗纠纷,确保医疗安全的积极作用。方法以某院2010年7月1日~2011年6月30日实施常规医疗安全管理为对照组,以实施六西格玛后的2011年7月1日~2012年6月30日为干预组,分析六西格玛对医疗安全系数(MSC)及医疗纠纷发生率的影响。结果干预组医院MSC从0.73±0.21提高到0.91±0.28(P=0.025),医疗纠纷发生率从百万分之2606.1降低至百万分之1538.5(P=0.032),Sigma水平从4.29提高到4.45。结论六西格玛的应用,可显著提高医疗安全系数(MSC),降低医疗纠纷发生率,是医疗安全管理的重要方法。
Objective To explore the effect of Six Sigma strategy for the prevention of medical disputes in hospital. Method The changes of MSC and the incidence of medical dispute between the two groups were analyzed : one group was inpatients after use of Six - Sigma strategy ( intervention group, from July 1, 2011 to June 30, 2012) and the other group was that immediately preceding institution of the strategy ( baseline group, from July 1, 2010, to June 30, 2011 ). Result After Six Sigma strategy, hospital MSC increased from 0.73 ± 0.21 to 0.91 ± 0.28 ( P = 0. 025) , the incidence of medical disputes decreased from 0.26% to 0.15 % ( P = 0. 032 ) , marked by an elevation of Sigma level from 4.29 to 4.45. Conclusion Six Sigma strategy re- sulted in a significant increase in hospital MSC, a decrease of incidence of medical disputes. These results support the adoption of Six Sigma strategy as an important method for medical safety management.
