Study summary

Vitamin D has been shown to impact prognosis in a variety of retrospective and randomized clinical trials within an intensive care unit (ICU) environment. Despite these findings, there have been no studies examining the impact of hypovitaminosis D in specialized neurocritical care units (NCCU). Given the often significant differences in the management of patients in NCCU and more generalized intensive care units there is a need for further inquiries into the impact of low vitamin D levels in this specific environment. This study proposes a randomized, double-blinded, placebo-controlled, single center evaluation of vitamin D supplementation in the emergent NCCU patient population. The primary outcome will involve length-of-stay for emergent neurocritical care patients. Various secondary outcomes, including in-hospital mortality, ICU length-of-stay, Glasgow Outcome Score on discharge, complications and quality-of-life metrics. Patients will be followed for 6 months post-discharge.

Read the detailed description

Vitamin D has been shown as an important marker of prognosis in a variety of clinical settings, including overall mortality, acute respiratory distress syndrome (ARDS), infection/sepsis, asthma, cardiovascular disease, diabetes, and pediatric/medical/surgical intensive care unit outcomes. Vitamin D not only plays a role in bone maintenance, but also a variety of extra-axial functions including immune-dysregulation and systemic inflammation. In addition, a number of randomized clinical trials support the supplementation of vitamin D as improving outcome in critical care patients. While the evaluation of vitamin D levels remains a standard-of-care at our institution, the widespread use of vitamin D monitoring and impact on neurocritical care patients remains limited. The investigators' recent prospective observational study of vitamin D levels in neurocritical patients showed that deficiency (\<20ng/dL) was highly associated with prolonged hospital stay and increased in-hospital mortality for emergent patients. Moreover, a number of limitations arise from this study due to its observational nature. This study proposes a randomized, double-blinded, placebo-controlled, single center evaluation of vitamin D supplementation in the neurocritical care patient population. Patients admitted to the neurocritical care unit for emergent cases and with vitamin D deficiency (\<20ng/dL) will undergo vitamin D serum draw on admission and be randomized to receive cholecalciferol/vitamin D3 supplementation (540,000 IU once orally) or placebo. The primary outcome measured will be hospital length-of-stay. Secondary outcomes will include length of ICU course, complications, medication adverse events, discharge Glasgow Outcome Score, in-hospital and 30-day mortality, as well as quality-of-life. Power analysis estimates 198 patients will be needed for each subgroup to determine a 2 day difference in length-of-stay, and the study plans to recruit 218 patients per treatment arm to account for dropout, which will take approximately 6-9 months to recruit. Interim analysis and safety monitoring will be performed. The investigators hypothesize that vitamin D supplementation may make a significant impact on reducing morbidity and mortality in the neurocritical care population. The possibility of reducing hospital length of stay and mortality from a simple, safe, and cost-effective intervention such as vitamin D supplementation may be a useful adjuvant treatment in the neurocritical care population.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jun 15, 2022, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
