Zusammenfassung:Hyperglycemia is common and may be a risk factor for nosocomial infections, including central catheter-associated bloodstream infections in critically ill children. It is unknown whether hyperglycemia at the time of acquiring central catheter-associated bloodstream infections in pediatric critical illness is associated with worse outcomes. We hypothesized that hyperglycemia (blood glucose concentration > 126 mg/dL [> 7 mmol/L]) at the time of acquiring central catheter-associated bloodstream infections (from 4 d prior to the day of first positive blood culture, i.e., central catheter-associated bloodstream infections) in critically ill children is common and associated with ICU mortality. Retrospective observational cohort study. Fifty-five-bed PICU and 26-bed cardiac ICU at an academic freestanding children's hospital. One hundred sixteen consecutively admitted critically ill children from January 1, 2008, to June 30, 2012, who were 0-21 years with central catheter-associated bloodstream infections were included. We excluded children with diabetes mellitus, metabolic disorders, and those with a "do not attempt resuscitation" order. None. The study cohort had an overall ICU mortality of 23%, with 48% of subjects developing hyperglycemia at the time of acquiring central catheter-associated bloodstream infections. Compared with survivors, nonsurvivors experienced more hyperglycemia both at the time of acquiring central catheter-associated bloodstream infections and subsequently. Median blood glucose at the time of acquiring central catheter-associated bloodstream infections was higher in nonsurvivors compared with survivors (139.5 mg/dL [7.7 mmol/L] vs 111 mg/dL [6.2 mmol/L]; p < 0.001) with 70% of nonsurvivors experiencing blood glucose greater than 126 mg/dL (> 7 mmol/L) during the 7 days following central catheter-associated bloodstream infections (in comparison to 45% of survivors; p = 0.03). After controlling for severity of illness and interventions, hyperglycemia at the time of acquiring central catheter-associated bloodstream infections was independently associated with ICU mortality (adjusted odds ratio, 1.9; 95% CI, 1.1-6.4; p = 0.03), in addition to other risk factors for ICU mortality (vasopressor use and severity of organ dysfunction). Hyperglycemia at the time of acquiring central catheter-associated bloodstream infections is common and associated with ICU mortality in critically ill children.
