Abstract:
Objective To understand the occurrence of catheter-associated urinary tract infection(CAUTI)in pa-tients with catheterization,and provide evidence for reducing the incidence of CAUTI.Methods Based on monito-ring requirement for CAUTI in competency building project of healthcare-associated infection(HAI)prevention and control established by Hospital Infection Management Committee of Chinese Hospital Association,CAUTI among patients who hospitalized and received urinary catheterization ≥2 days in a hospital from January to December 2014 were analyzed prospectively,incidences of CAUTI in different patients were compared.Results A total of 6 046 patients with urinary catheterization were monitored,166 of whom developed CAUTI,incidence of CAUTI was 2.75%,the total urinary catheter days were 31 833 days,incidence of CAUTI was 5.21 per 1 000 urinary catheter days.There was no significant difference in the incidence of CAUTI among patients of different genders (χ2 =1 .23, P =0.54);incidence of CAUTI in patients > 60 years old was higher than those ≤60 years (4.72% vs 2.07%,χ2=30.38,P <0.01);incidence of CAUTI in patients with different duration of catheterization was significantly dif-ferent(χ2 = 251 .14,P <0.01 );with the prolongation of duration of catheterization,incidence of CAUTI also in-creased(trendχ2 =211 .82,P <0.001 ).Patients in department of neurology had the longest average catheterization time(14.84 days)and highest incidence of CAUTI(15.00%,10.11 ‰);patients in the other departments of surgery had the shortest average catheterization time(3.56 days)and lowest incidence of CAUTI(0.97%,2.74‰);inci-dences of CAUTI in patients with urinary catheterization in different departments were significantly different(χ2 =302.24,P <0.001).166 CAUTI patients were isolated 66 isolates of pathogenic strains,86.36% were gram-nega-tive bacilli,33.33% of which were Escherichia coli .Conclusion CAUTI is related to the age of patients and dura-tion of indwelling urinary catheter.Daily assessment on the necessity of indwelling catheter and timely removal of catheter is helpful for reducing the occurrence of CAUTI.
