BACKGROUND/RATIONALE:
This project is a prospective measurement and outcomes study of persons in a state of disordered consciouness after severe brain injury. Medical and rehabilitation management during coma recovery and scientific investigations of coma recovery have been hampered by an inability to provide evidence based prognoses and to measure treatment effects. This project aims to enhance the provision of healthcare services to our veterans and military personnel who are in states of disordered consciousness after incurring severe TBI.

OBJECTIVE(S):
The purpose of this study is to enhance neurobehavioral measurement and prognostication after severe TBI. This will be done in Three Steps: (1) Enhance the Disorders of Consciousness Scale (DOCS), (2) Examine the performance characteristics of the finalized DOCS, and (3) Explore associations between the DOCS and other variables known or thought to be important to outcome prediction. The research objectives are to shorten the DOCS from 23 items (20-30 minutes) to 15-20 items (15-20 minutes) while improving the predictive value of the DOCS; thereby enhancing clinical utility, to determine what performance characteristics of the DOCS are important to predicting recovery of consciousness and 1-year functional outcomes and to determine how DOCS change performs as a predictor variable in a model including other variables known or thought to be important to outcome prediction.

METHODS:
This study builds on previous research and it is the third phase of a longitudinal measurement and outcomes study. Persons > = 18 years of age with severe TBI who have been unconscious for > = 28 days consecutively and are within 180 days of injury are eligible for study enrollment. Target sample size is 193 subjects who are each followed for one year. The independent variables being collected and examined for prognostic utility include the DOCS and other Neurobehavioral Variables, Injury and Lesion Characteristics, Physiological Data, Etiology, Cause of Injury, Demographics, Comorbidities, Rehabilitation Services received and indices of Injury Severity. The primary outcome is recovery of consciousness within the first year of injury and the secondary outcome is functional outcome 1-year after injury.

FINDINGS/RESULTS:
For persons with prolonged disorders of consciousness after a severe brain injury, findings indicate that the DOCS test can be shortened to 20 test items with some loss in precision, but with an overall high level of predictive accuracy. The accuracy of predicting recovery and lack of recovery of consciousness is balanced. In summary, the DOCS measures, after rater severity/leniency calibration, are strong predictors of recovery of consciousness at two time points in the first year of recovery.

IMPACT:
The significance of the research is related to the VA's mission to provide medical care that maximizes each veteran's quality of life.. This research addresses the VA's mission to provide veterans and service members with evidence based medical rehabilitation.
