摘　　要：目的:分析医院消毒供应中心(CSSD)医疗器械超声波清洗效果的相关影响因素及改进策略实践效果。方法:选取医院CSSD 2022年3-6月使用超声波清洗的医疗器械,采用Logistic回归模型对影响医疗器械清洗效果的因素进行分析,并制定相应的改进策略。选取2022年7-9月实施改进策略后超声波清洗清洗的医疗器械,对比实施改进策略前后的清洗效果。结果:实施改进策略前,医疗器械465次超声波清洗中,发生清洗质量不合格41次,清洗质量合格424次,合格率为91.18%。经Logistic回归分析,预冲洗规范性、水质、清洗介质和清洗条件是否合格均为CCSD医疗器械超声波清洗效果的独立影响因素(OR=6.673,OR=5.140,OR=3.983,OR=5.023;P<0.05)。实施改进策略后,在医疗器械465次超声波清洗中,未出现清洗质量不合格,清洗合格率为100%,高于实施改进策略前,差异有统计学意义(x^(2)=42.891,P<0.001)。结论:医院CCSD医疗器械超声波清洗效果的独立影响因素分别为预冲洗规范性、水质、清洗介质和清洗条件,针对上述因素制定改进措施,清洗效果可显著改善。Objective:To analyze the relevant influence factors and the practical effects of improvement strategies of ultrasonic cleaning effect on medical apparatuses of central sterile supply department(CSSD)of hospital.Methods:The medical apparatuses were cleaned by ultrasound in hospital between March and June 2022 were selected.The influencing factors of cleaning effect of medical apparatuses were analyzed by Logistic regression model,and the corresponding improvement strategies were formulated according to the above factors.The medical apparatuses during the period from July to September 2022 after the improvement strategies were implemented were selected to compare the cleaning effects between before and after implemented improvement strategies.Results:Before the improvement strategies were implemented,the cleaning qualities of 41 times were not quality in the cleaning of 465 times for medical apparatuses,and the cleaning qualities of 424 times were quality,which qualified rate of cleaning was 91.18%.The results of Logistic regression analysis showed that whether the normalization of pre-washing,water quality,cleaning medium and cleaning conditions were qualified were independent influence factors of ultrasonic cleaning effect of CCSD medical apparatuses(OR=6.673,OR=5.140,OR=3.983,OR=5.023,P<0.05).After the improvement strategy was implemented,there was not unqualified cleaning in the cleanings of 465 times of medical apparatuses,and the qualified rate of cleaning was 100%,which was higher than that before improvement strategy was implemented(x^(2)=42.891,P<0.001).Conclusion:The independent influence factors of the ultrasonic cleaning effect of CCSD medical apparatuses were respectively the normalization of pre-washing,water quality,cleaning medium and cleaning conditions.The formulated improvement measures based on the above factors can significant improve the cleaning effect.
