Effects of vitamin D deficiency on prognosis in intensive care unit patients

Aim: Vitamin D deficiency is frequently observed in intensive care unit patients, but its clinical effects on patients are still debated.The aim of this study is to determine the prevalence of vitamin D deficiency in intensive care patients and its effect on patient outcomes and mortality.Methods: 384 patients accepted to the study were divided into two groups as patients with (Group 1) and without (Group 2) Vitamin D deficiency according to their 25(OH)D levels.Demographic data of the patients, APACHE-2 scores, additional diseases, laboratory data, mechanical ventilation needs, follow-up periods in the intensive care unit, and mortality rates were recorded retrospectively from patient records.Results: Vitamin D deficiency was detected in 279 of the patients.The two groups were similar in terms of demographic characteristics of the patients.There was no significant difference between the two groups in terms of APACHE-2 scores, length of stay in the intensive care unit, need for endotracheal intubation, and mortality rates.The incidence of septicemia and infection parameters was significantly higher in the group with vitamin D deficiency (p
