Worsening severity of vitamin D deficiency is associated with increased length of stay surgical intensive care unit cost and mortality rate in surgical intensive care unit patients

摘要

BACKGROUNDVitamin D deficiency is the most common nutritional deficiency in the United States. It is seldom measured or recognized, and rarely is treated, particularly in critically ill patients. The purpose of this study was to investigate the prevalence and impact of vitamin D deficiency in surgical intensive care unit patients. We hypothesized that severe vitamin D deficiency increases the length of stay, mortality rate, and cost in critically ill patients admitted to surgical intensive care units.
