Factors related to bloodstream infections in patients with catheter-associated urinary tract infections aged over 80 years / 中华老年医学杂志

ABSTRACT

Objective:To investigate factors related to bloodstream infections in patients with catheter-associated urinary tract infections(CAUTI)aged over 80 years.Methods:Clinical data of patients with CAUTI aged 80 years in our hospital from August 2014 to September 2019 were retrospectively analyzed.Independent and relevant factors for bloodstream infections in patients were analyzed by using univariate and multivariate methods with SPSS20.0 statistical software.Results:There were 138 patients with bloodstream infections, giving an infection rate of 9.28%.Univariate and multivariate analysis showed that the timing of catheterization(delayed or no extubation after infection), urinary tract operation, glucocorticoid use, tumor chemotherapy, serum albumin concentration reduction, blood glucose and multi-drug resistant bacterial infection were independent risk factors for bloodstream infections in patients with CAUTI aged over 80 years.Conclusions:Early extubation, blood glucose control, correction of hypoproteinemia, reduction of multi-drug resistant bacterial infection, rational use of glucocorticoids and tumor chemotherapy, and heightened attention to patients undergoing urinary tract surgery can reduce the risk of bloodstream infections in patients with CAUTI aged over 80 years.
