Vitamin D deficiency may frequently occur in critically ill patients and may be associated with sepsis and increased mortality. We therefore evaluated the prevalence of 25-hydroxyvitamin D deficiency in a Dutch ICU, and its relationship with sepsis, morbidity and mortality.
We conducted a prospective observational study in a 10-bed mixed ICU. A total of 1,372 patients were admitted between July 2011 and June 2013 including 198 readmissions, of which 940 patients were studied. 25-Hydroxyvitamin D levels were determined within 24 hours after admission. 25-Hydroxyvitamin D levels were judged as sufficiency (>50 nmol/l), insufficiency (30 to 50 nmol/l) and deficiency (<30 nmol/l).
The prevalence of deficiency and insufficiency was 36% and 38%, respectively. Only 26% of the patients had sufficient vitamin D levels. Vitamin D deficiency is associated with sepsis (P < 0.001) at ICU admission. Patients with deficient levels had higher mean APACHE IV scores, 64 versus 52 (P < 0.001), and longer length of hospital stay, 12 versus 9 days (P < 0.001), respectively, as compared with patients with sufficient levels. Patients with deficient vitamin D levels had an odds ratio for in-hospital mortality of 1.4 (95% confidence interval of 0.84 to 2.29, P = 0.2) relative to patients with sufficient vitamin D levels.
25-Hydroxyvitamin D deficiency frequently occurs in Dutch critically ill patients. Although relating to sepsis, disease severity and morbidity, vitamin D deficiency is not an independent predictor of mortality in these patients, which was otherwise relatively low.
