ABSTRACT
Objective To explore the continuous improvement to reduce the suctioning pediatrics lumen instruments return-cleaning rate of the first time washing, improve work efficiency and reduce the cost by applying root cause analysis. Methods Using causal analysis of fishbone diagram to analysis and verify the main reason of leading to high lumen instruments return-cleaning rate. According to the three terminal factors of continuous quality improvement, quality control group was set up, lumen instruments cleaning quality control standards was made, water flow mode of lumen instruments cleaning was changed, selected the appropriate cleaning tools and real picture show, synchronize quality control measures of publishing the quality and safety board. Compared before and after return-cleaning rate of three different detection methods and the different parts of the same suction lumen instruments. Results Before carrying out eye-measurement, cotton swab to wipe, ATP bioluminescence back washing rate was 0.89% (2/225), 7.11%(16/225), 27.11%(61/225), respectively after implementation of 0, 0.44%(1/226), 3.98%(9/226), visual observation before and after the return rate of washing was no statistically significant difference (χ2=2.018, P>0.05);Cotton swab to wipe, ATP bioluminescence back washing rate difference was statistically significant (χ2=13.820, 45.999, P0.05). Conclusions ATP bioluminescence assay has fine effects to detect the return-washing rate of the inner wall of the lumen instruments. The Root Cause Analysis method significantly reduced the return-washing rate of the inside surface of the suction lumen instruments, improve the efficiency, save the medical cost and reduce the hospital infection.
ABSTRACT
Objective To improve the cleaning quality of reusable medical instruments continuously through root cause analysis,reduce healthcare-associated infection(HAI)and the wear and tear of instruments.Methods The major factors influencing the cleaning quality of instruments were analyzed and clarified by fishbone diagram,contin-uous quality improvement was carried out based on 5 terminal factors,the rate of rusting,stain,repeated cleaning, damage,and clinical department satisfaction before and after the implementation of continuous improvement were compared.Results The qualified rate of instrument clean increased from 94.24% before implementing measures to 97.60% after implementing measures,the rate of rusting,stain,repeated cleaning,damage decreased from 3.39%, 2.37%,5.76%,and 2.08% to 1 .55%,0.85%,2.40%,and 0.48% respectively,there were significant difference among different groups(all P <0.001 );the score of satisfaction rate to central sterile supply department elevated from(93.87±3.87)before implementing measures to (98.08 ±0.59)after implementing measures(t =6.80,P <0.001).Conclusion Root cause analysis is important in improving cleaning quality of reusable instruments continu-ously,as well as reducing HAI and the wear and tear of instrument,it can save medical cost.
