Objective To explore the methods for reducing the consumption of cleaning water and sterilization water in hospital disinfection supply centers.Methods The water-using equipment equipped in the disinfection supply center of a hospi-tal from December 2023 to December 2024 was selected as the research subject,and a water usage optimization plan based on to-tal productive maintenance(TPM)was implemented on the subject in the center for 6 months.The reduction rate of water con-sumption,equipment operation efficiency,cost-effectiveness of water conservation,process efficiency,as well as the participation and satisfaction of employees in the new strategy were compared before and after the intervention.Results After intervention,the total water consumption in the center was significantly reduced[(5 494.66±544.85)m3 vs.(4 652.35±702.22)m3],the time for cleaning equipment was shortened[(38.16±4.99)min vs.(47.58±1.39)min],the time for equipment sterilization[(36.84±1.83)min vs.(47.24±1.13)min].The failure rate of the cleaning equipment was lowered(0.00％vs.4.00％).The water cost was decreased[(12 423.88±1 319.74)yuan vs.(10 214.84±979.30)yuan].The total cleaning and sterili-zation time was significantly shortened[(2.45±0.27)h vs.(1.29±0.26)h,(P＜0.05)].The water consumption was re-duced by 4.68％,and the total rate of satisfaction and participation of employees was 92.3％.Conclusion The optimization scheme for cleaning water in disinfection supply centers based on TPM can effectively reduce water consumption,save water costs,improve the operational efficiency of equipment,process efficiency,and participation and satisfaction of employees.It is worthy of promotion and application in medical institutions.

Objective To evaluate the effect of evidence-based bundle intervention strategy on reducing the inci-dence of central line-associated bloodstream infection (CLABSI).Methods Prospective and multicenter study was adopted,patients admitted to 54 intensive care units (ICUs)of 41 hospitals and with central venous catheters (CVCs)between October 1 ,2013 and September 30,2014 were monitored .Baseline data between October 2013 and March 2014 were collected as pre-intervention data;from April to September 2014,the participated hospitals performed intervention strategy,post-intervention data were compared with pre-intervention data.Results The usage rate of CVCs before and after intervention was significantly different (44.18% vs 44.63%,χ2 =5.526,P =0.019).Incidence of CLABSI before and after intervention was not significantly different(RR ,0.82[95%CI ,0.59-1 .13],P =0.10).Constituent ratio of catheter insertion sites between pre-and post-intervention was significantly different (χ2 =76.264,P <0.001),femoral vein catheterization rate as well as proportion of two and above catheter insertion sites after intervention decreased(17.25% VS 13.72%;2.27% VS 1 .44%,respectively);hand hygiene implementation rate and accuracy rate after intervention were both higher than before intervention (79.73% vs 76.14%,P <0.001 ;91 .47% vs 74.26%,P <0.001 ,respectively);constituent ratio of skin disinfectant applica-tion before and after intervention was significantly different(χ2 =3.861 ,P <0.001 ),proportion of chlorhexidine ethanol increased (29.62% VS 50.56%);except daily assessment and record,compliance to other prevention and control measures before and after intervention were all significantly different(all P <0.001);utilization rate of max-imal sterile barrier,qualified rate of dressing of operators,and port disinfection were all significantly enhanced. Conclusion Bundle intervention in intubation and maintenance are implemented effectively,but intervention effect on CLABSI needs further study.
