Analysis of pathogenic bacteria detection and risk factors in patients with urinary tract infection combined with bloodstream infection
Objective To analyze the distribution characteristics of pathogenic bacteria in urine and blood culture samples of patients with urinary tract infection combined with bloodstream infection,and explore the risk factors of concurrent bloodstream infection,and guide clinical development of targeted prevention and treatment measures.Methods The clinical data of 160 patients with urinary tract infection were retrospectively analyzed.The etiological characteristics of urinary tract infection combined with bloodstream infection were analyzed.The general data and relevant data of urinary tract infection were compared between blood stream infection group and non-blood stream infection group,and the risk factors of urinary tract infection with bloodstream infection were analyzed.Results Among 160 patients with urinary tract infection,28 cases(17.50%)were complicated with bloodstream infection.Blood cultures of 28 patients with urinary tract infection and blood stream infections isolated 35 strains of pathogenic bacteria.In blood stream infection group,the percentages of≥80 years of age,absolutely bedridden,diabetes history,primary urinary system disease,Foley catheter retention≥7 d,multi-drug resistant bacteria infection history,and urinary tract surgery history were 46.43%,39.29%,39.29%,32.14%,71.43%,50.00%,and 32.14%,which were significantly higher than 15.15%,19.70%,18.18%,15.91%,38.64%,30.30%,and 15.15%in the non-bloodstream infection group(P<0.05).Multivariate Logistic regression analysis showed that urinary tract surgery history,multi-drug resistant bacteria infection history,diabetes history,and Foley catheter retention≥7 d were risk factors for urinary tract infection combined with bloodstream infection(P<0.05).Conclusion The pathogenic bacteria of urinary tract infection combined with blood flow infection are mostly gram-negative bacteria.The occurrence of combined infection is closely related to diabetes,multi drug resistant bacteria infection,urinary tract surgery,and long Foley catheter retention.Therefore,clinical risk assessment of patients with urinary tract infection should be strengthened,and early intervention and close monitoring should be carried out to prevent blood flow infection.
