Vitamin D levels in paediatric intensive care unit patients and its relation to severity of illness: An Indian experience

Abstract

\u2009Vitamin D deficiency is a common disorder that is associated with morbidity and mortality in the general population. We conducted a cross-sectional study of 384 children admitted to paediatric intensive care to determine its prevalence and association with severity of illness and outcome in critically ill children. The severity of illness was evaluated using the paediatric risk of mortality score (PRISM III), on admission, at 24 and 48\u2009h. Vitamin D deficiency was observed in 175 children (45.6%) and was associated with higher severity of illness, need for mechanical ventilation and increased mortality.
