A multicenter study analyzing the association of vitamin D deficiency and replacement with infectious outcomes in patients with burn injuries

In burn patients, vitamin D deficiency has been associated with increased incidence of sepsis and infectious complications. The objective of this study was to assess the impact of vitamin D deficiency in adult burn patients on hospital length of stay (LOS). This was a multi-center retrospective study of adult patients at 7 burn centers admitted over a 3.5 year period, who had a 25-hydroxyvitamin D concentration drawn within the first 7 days of injury. Of 1,147 patients screened, 412 were included. Fifty-seven percent were vitamin D deficient. Patients with vitamin D deficiency had longer LOS (18.0 vs 12.0 days, p < 0.001), acute kidney injury (AKI) requiring renal replacement therapy (7.3 vs 1.7%, p = 0.009), more days requiring vasopressors (mean 1.24 vs 0.58 days, p = 0.008), and fewer ventilator free days of the first 28 days (mean 22.9 vs 25.1, p < 0.001). Univariable analysis identified burn center, AKI, TBSA, inhalation injury, admission concentration, days until concentration drawn, days until initiating supplementation, and dose as significantly associated with LOS. After controlling for center, TBSA, age, and inhalation injury, vitamin D deficiency was associated with longer LOS. In conclusion, patients with thermal injuries and vitamin D deficiency on admission have increased length of stay and worsened clinical outcomes as compared to patients with non-deficient vitamin D concentrations.
