Effect of target intervention on preventing catheter-related bloodstream infection / 中国基层医药

ABSTRACT

Objective To investigate the effectiveness of target intervention in preventing catheter -related bloodstream infection ( CRBSI ) .Methods The targeted monitoring was launched by changing venepuncture site , reinforcing instructions in aseptic insertion technique and hand hygiene supervision ,avoiding femoral access and remo-ving unnecessary catheters ,venous puncture implemented by high qualification anesthesiologist ,then the incidence of CRBSI before and after the project was compared .Results The incidence of CRBSI after the project decreased signif-icantly from 17.97%to 4.32%,the difference was statistically significant (χ2 =40.82,P<0.05).Chi-square test and logistic regression analysis showed that the incidence of infection was increased in patients with catheter for longer than 10 days (χ2 =4.33,P<0.05),the incidence of CRBSI was decreased in patients that central venous puncture implemented by high qualification anesthesiologist (χ2 =9.21,P<0.05),and patients received catheter indwelling into femoral vein had increased incidence of CRBS (χ2 =7.45,P<0.05).Conclusion Indwelling catheter time, unskilled operator ,catheter site are risk factors in patients with CRBSI .In response to these factors ,we should develop interventions to maximize establish a protective barrier , improve the quality of the medical operation , prevent the occurrence of CRBSI more efficiently .
