ABSTRACT
Objective To explore the incidence of surgical site infection (SSI)and compliance to bundled interven-tion measures,and evaluate the effect of bundled interventions on controlling SSI.Methods From October 2013 to September 2014,three types of surgeries (colorectal surgery,abdominal hysterectomy,and femoral neck repair sur-gery)in 29 hospitals in China were monitored,October 2013 to March 2014 was baseline investigated stage,April 2014 to September 2014 was intervention stage.Results A total of 6 166 episodes of surgeries were monitored,the incidence of SSI was 1 .64%,incidence of SSI following colorectal surgery,abdominal hysterectomy,and femoral neck repair surgery were 4.47%,1 .03%,and 0.21 % respectively.The P 75 time of three types of surgeries were 3,2,and 2 hours respectively.Compared with the baseline stage,the compliance to most intervention measures im-proved after intervention,the largest increase in the compliance to interventions was disinfection with chlorhexidine-containing disinfectant at surgical sites of colorectal surgery (increased by 29.09%),followed by preoperative shower of femoral neck repair surgery (increased by 26.24%),preoperative shower of colorectal surgery(increased by 22.95%),and skin preparation on the day of operation (increased by 20.75%).Incidences of SSI in three types of surgeries were not significantly different before and after intervention(all P >0.05).Conclusion The incidences of SSI are different among different types of surgeries,the compliance to most bundled intervention measures has im-proved to some extent after intervention,but effectiveness of intervention measures needs to be further observed.
ABSTRACT
Objective To investigate the status and risk factors of surgical site infection (SSI)in hospitals in Chi-na,so as to provide theoretical basis for the prevention and treatment of SSI.Methods Four types of surgeries (colorectal surgery,abdominal hysterectomy,femoral neck repair surgery,and vascular surgery)in 29 hospitals were monitored prospectively,risk factors for SSI were analyzed.Results A total of 6 309 surgical procedures were investigated,incidence of SSI was 1 .60%.Incidences of SSI in patients receiving colorectal surgery,abdominal hys-terectomy,femoral neck repair surgery,and vascular surgery were 4.47%(74/1 655 ),1 .03%(22/2 139),0.21 %(5/2 372),and 0.00% (0/143 )respectively.The incidences of SSI were different among different regions (χ2 =114.213,P <0.05).The most common SSI was superficial incisional infection,the next was deep incisional infec-tion.The major pathogens causing SSI were Escherichia coli ,Enterococcus spp .,coagulase negative staphylococ-cus ,Staphylococcus aureus ,and Klebsiella pneumoniae .The independent risk factors for SSI were male patients, long duration of surgery,and high NNIS score.Conclusion The risk of SSI is varied with different types of surger-ies.Male,long duration of surgery,and high NNIS score can increase the risk of postoperative SSI.
ABSTRACT
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.
ABSTRACT
Objective To increase acupuncture doctors' compliance on hand-washing, with which cross-infection can be avoided and the security level of acupuncture can be raised. Methods To get the information on current situation of hand-washing by direct observation. Aiming at present issues, we adopted such measures as improving hand-cleaning facilities and intensifying training of hand health knowledge and hand health manipulations to prevent them. Such methods as self reporting, indirect measuring, inquiring patients, and tracking surveys were used to evaluate the effects. Results Executive rate of hand-cleaning was 14% and 79% before and after the measures' intervention respectively. Conclusion As needles are inserted into the skin for the treatment, these needles may contaminate the blood or tissue fluid of the patient. The insanitation of hand may increase this contagious risk. Therefore, we must guide the acupuncturists to pay attention to their hands sanitation.
