Forensic consultation regarding moderate and severe closed head injury (CHI) generally focuses on determination of severity of residual deficits and the implications of these deficits for future health care needs, personal independence, and employment. This information can be used to develop a life care plan that describes the patient's needs for continued medical care, rehabilitation, and daily assistance or supervision and estimates the long-term costs for these services. This article provides brief reviews of CHI classification, epidemiology, residual deficits, expected outcomes, and factors predictive of outcome. An introduction to the process of developing a life care plan is presented.
