Brief Summary
This ancillary study will determine if early administration of a single high-dose (540,000 IU) oral vitamin D3 (cholecalciferol) treatment improves 12-month global cognition and executive function as determined by comprehensive neuropsychological testing in 140 critically ill patients with Vitamin D deficiency at enrollment.

Outcome Measures
Primary Outcomes (2)
12-month Cognition as Measured by the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS)
The RBANS is a comprehensive neuropsychological battery for the evaluation of global cognition and has been validated in subjects with mild cognitive impairment, moderate to severe traumatic brain injuries, vascular dementias, and Alzheimer's disease. It specifically tests for for immediate and delayed memory, attention, visuospatial construction, and language. Scores range from 0 to 160 with 100 representing the population average. Higher score represents better cognition.
12 (+/- 4) months
12-month Executive Function as Measured by the Components of the Delis-Kaplan Executive Function System (D-KEFS) Subscales.
The D-KEF's Proverbs, Number-Letter Switching, and Verbal Fluency Category Switching subscales will measure conceptual flexibility, inhibition, and monitoring, respecitvely, which encompasses the majority of executive function. The average of the three subscales will provide an executive function composite score. Scores range from 1 to 18; 10 is considered normal, and higher values indicate better executive function.

Study Arms (2)
Intervention
Patients who received high dose D3 and completed the neuropsychological evaluations at 12 (+/-4) months after randomization.

Interventions
This intervention was administered as part of VIOLET parent study. A single dose of 540,000 IU vitamin D3 was administered within 2 hours of randomization time.

This data sharing plan is only pertinent to data collected specifically for VIOLET-BUD. Because VIOLET-BUD is an ancillary study to a Prevention and Early Treatment of Acute Lung Injury (PETAL) network study, the same data sharing plan will be instituted as the PETAL Clinical Coordinating Center. Limited access data sets will be prepared and provided to the NHLBI in accordance with National, Heart, Lung and Blood Institute (NHLBI) policies on data sharing: http://www.nhlbi.nih.gov/research/funding/human-subjects/set-preparation-guidelines. VIOLET-BUD data will be made available on the Biologic Specimen and Data Repository Information Coordinating Center (BioLINCC). In addition to the data, documentation such as data collection forms, study procedures and protocols, data dictionaries and algorithms for calculated data elements and descriptions of all variable recoding performed will also be provided.
