Abstract
Objectives
To analyze the association between glycemia levels upon pediatric intensive
care unit admission and mortality in patients hospitalized.
Methods
A retrospective cohort of pediatric intensive care unit patients admitted to
the Instituto Nacional de Salud del Niño between
2012 and 2013. A Poisson regression model with robust variance was used to
quantify the association. Diagnostic test performance evaluation was used to
describe the sensitivity, specificity, positive predictive value, negative
predictive value and likelihood ratios for each range of glycemia.
Results
In total, 552 patients were included (median age 23 months, age range 5
months to 79.8 months). The mean glycemia level upon admission was
121.3mg/dL (6.73mmol/L). Ninety-two (16.6%) patients died during
hospitalization. In multivariable analyses, significant associations were
found between glycemia < 65mg/dL (3.61mmol/L) (RR: 2.01, 95%CI 1.14 -
3.53), glycemia > 200mg/dL (> 11.1mmol/L) (RR: 2.91, 95%CI 1.71 -
4.55), malnutrition (RR: 1.53, 95%CI 1.04 - 2.25), mechanical ventilation
(RR: 3.71, 95%CI 1.17 - 11.76) and mortality at discharge. There was low
sensitivity (between 17.39% and 39.13%) and high specificity (between 49.13%
and 91.74%) for different glucose cut-off levels.
Conclusion
There was an increased risk of death at discharge in patients who developed
hypoglycemia and hyperglycemia upon admission to the pediatric intensive
care unit. Certain glucose ranges (> 200mg/dL (> 11.1mmol/L) and <
65mg/dL (3.61mmol/L)) have high specificity as predictors of death at
discharge.
