Lee P. Vitamin D metabolism and deficiency in critical illness. - see below
- “Collectively these results provide unequivocal evidence that vitamin D insufficiency and deficiency are highly prevalent among critically ill patients.”
- “These results demonstrate current replacement regimes are grossly inadequate.”
He ends by citing studies showing death in the ICU and the CCU is 2-3 times higher for the vitamin D deficient.

Vitamin D deficiency is highly prevalent and has been associated with a diverse range of chronic medical conditions in the general population.
In contrast, the prevalence, pathogenesis and significance of vitamin D deficiency have received little attention in acute medicine.
Vitamin D deficiency is seldom considered and rarely corrected adequately, if at all, in critically ill patients.
Recent recognition of the extra-skeletal, pleiotropic actions of vitamin D in
- epithelial function and
- metabolic regulation
may underlie the previously under-recognized contribution of vitamin D deficiency to typical co-morbidities in critically ill patients, including
- systemic inflammatory response syndrome and
- metabolic dysfunction.
Improved understanding of vitamin D metabolism and regulation in critical illness may allow therapeutic exploitation of vitamin D to improve outcome in critically ill patients.

- All items in After surgery or trauma 55 items as of Feb 2012
- 540,000 IU active vitamin D before ICU raised vitamin D level average at least 25 ng – March 2011
- ICU time is 2X more likely to be longer than 2 days if vitamin D less than 20 ng – Mar 2011
- Health Care Providers save $ by providing vitamin D before and/or after surgery or trauma - reduces the time in bed, etc.
- Virtually all veterans in ICU had vitamin D less than 32 ng – Jan 2011
