Application of Lean Six Sigma in medical waste management
摘要
Abstract
Objective To evaluate the effect of Lean Six Sigma (LSS)on intervening in medical waste management in a hospital,and evaluate the intervention effect.Methods Medical waste disposal in inpatient departments and op-erating rooms in a tertiary first-class hospital were investigated,13 inpatient departments were randomly chosen for study. December 2014-March 2015 was pre-intervention stage,baseline data of medical waste management were surveyed,April-July 2015 was post-intervention stage,LSS DMAIC (define,measure,analyze,improve,control) process was used to standardize process of the classification and disposal of medical waste,management effect was evaluated.Results Analysis on factors influencing the cost of medical waste disposal revealed that there were 7 in-fluencing factors,and that presenting 4 progressive structures,undefined responsibility of administration depart-ment was the root cause,which led to the different standards for medical waste classification,and eventually influ-enced the cost of medical waste disposal. The qualified rates of medical waste classification in inpatient departments and operating rooms increased from 69.22% and 71 .88% before intervention to 80.42% and 81 .00% after inter-vention respectively,difference were both significant(both P<0.01);medical waste weight in inpatient departments decreased from (1.11±0.14)kg/bed-day to (0.91±0.18)kg/bed-day,and that in operating room decreased from (10.77±0.33)kg/bed-day to (7.26±1.04)kg/bed-day(both P<0.05). The benefit-cost ratio was 6.09,that is, 1-yuan investment could save 6 .09 yuan.Conclusion LSS management method can effectively reduce medical waste weight and cost of every hospitalization day,and it has certain health economic value.关键词
