Abstract
Objective
Third-generation cephalosporin-resistant (3GC-R) bloodstream infection (BSI) is associated with poor prognosis. We investigated the incidence of and risk factors for 3GC-R Escherichia coli (E. coli) BSI in children.
Methods
Patients with E. coli BSIs who were hospitalized at the Children's Hospital of Chongqing Medical University were retrospectively enrolled. Univariate and multivariate logistic regression analyses were used to identify the independent risk factors for 3GC-R BSI.
Results
Two hundred fifty-two children with E. coli BSIs were enrolled. The mortality rate was 11.51% (29/252). The infection rate of 3GC-R E. coli was 48.81% (123/252), and the incidence of E. coli BSI during hospitalization was 18.58 per 1000 person-days. Approximately half (47.22%, 119/252) of the children were infected with extended-spectrum beta-lactamases (ESBLs) produced by E. coli. More than one-third (37.30%, 94/252) of the children were unnecessarily administrated carbapenems. According to our logistic regression analysis, a history of carbapenem administration, an elevated Pediatric Sequential Organ Failure Assessment (pSOFA) score ≥2, and antimicrobial agent administration before blood culture were independently associated with 3GC-R BSI (odds ratio [OR] 2.05, 95% confidence interval [CI] 1.08-3.94, P=0.029; OR 2.00, 95% CI 1.10-3.71, P=0.025, OR 1.86, 95% CI 1.02-3.42, P=0.044, respectively).
Conclusion
In this study, the incidence of 3GC-R E. coli BSI among children was retrospectively evaluated. Patients with a history of carbapenem administration, an elevated pSOFA score ≥2 and who were administrated antimicrobial agents before blood culture had an increased risk of 3GC-R E. coli BSI.
