Introduction: Patients in intensive care units (ICUs) are at high risk of unfavorable outcomes. Considering the role of vitamin D (Vit D) in cardiovascular and immune functions, Vit D deficiency could affect ICU patients’ outcomes. This study aimed to evaluate Vit D status and its predictive value for outcome in ICU patients. Patients and Methods: A total of 169 ICU patients were followed during ICU stay. Primary outcome was the occurrence of at least one major adverse event; secondary outcomes were organ failure, septic shock, ICU-acquired infection, other adverse events, and ICU mortality. Plasma 25-hydroxyvitamin D (25(OH)D) was assessed by immunoassay. Multivariate Cox regression analyses were performed to test the associations of low 25(OH)D levels with poor outcomes. Results: Around 75% of patients had 25(OH)D levels Conclusions: Hypovitaminosis D is very common in ICU patients. Results of the present study show that low plasma 25(OH)D levels are associated with increased risk of unfavorable outcomes in these patients. Additional research is needed to investigate the impact of Vit D status and effect of Vit D supplementation in ICU patients.
