Vitamin D deficiency or VDD is a well-established cause of disease. Although severe deficiency is now rare, the occurrence of sub-clinical VDD in many adults and children “..may predispose them to neurologic, cardiovascular, respiratory, and immune pathology.”

This systematic review conducted by McNally et al. in 2017, published in Critical Care, sought to determine the frequency of Vitamin D deficiency (VDD) in paediatric critical illness and its associated clinical outcomes.

The study postulates that because of the effect of VDD on critical organ systems essential to the development of and recovery from critical illness, VDD has been hypothesized to be a risk factor for morbidity and mortality in the intensive care unit (ICU).

It considered 17 studies from 8 countries and five continents.  VDD was defined as a blood total 25(OH) D concentration under 50 nmol/L. 

The review determined that 50% of critically ill children have VDD at the time of ICU admission. This deficiency was associated with illness severity, increased need for ICU intervention, and increased mortality. ( OR 1.62, 95% CI 1.11–2.36)
