A new study sheds light on the prevalence and impact of vitamin D deficiency in critically ill cancer patients.

Vitamin D deficiency is common among cancer patients due to impaired nutritional status, avoidance of sunlight during prolonged hospitalization, cytotoxic therapy, and radiation, and Vitamin D deficiency is a risk factor for unfavorable outcomes following ICU treatment.

In the current study by Buchtele et al.  (1), the researchers found that severe vitamin D deficiency was an independent predictor of hospital mortality and 1-year mortality, but not of ICU mortality. The observed associations of severe vitamin D deficiency and post-ICU outcome warrants further research and clinical consideration.
