Relating mental health and physical function at discharge to rehabilitation status at three months postburn

Preinjury mental health is said to be a major predictive factor in the rehabilitation progress of burn patients. However, it is unclear which component of rehabilitation (emotional v physical) is predicted by this variable; furthermore, the predictive validity of preinjury mental health has not been compared with physical variables. The present study compared preinjury mental health, physical variables, and length of hospitalization in predicting the rehabilitation progress of 59 major burn patients at three-month follow-up. Preinjury mental health was assessed by the Rand Mental Health Form; physical status, by the Upper Extremity Index (standard measures of upper limb joint mobility); and hospital stay, by the number of days of acute hospitalization. These variables were assessed at the time of discharge. Three-month rehabilitation outcome was measured by the Sickness Impact Profile, a self-report inventory that evaluates patient outcome in 12 different areas. These areas were in turn placed in the categories of disability (ie, difficulties in functioning in activities of daily living; eating) handicap (ie, difficulties in functioning in general areas of living; employment) and mental health status. In predicting mental health status at three months, preinjury mental health was significantly correlated. In predicting physical disability, physical factors were found to be important. Conversely, physical status was not significantly related to mental health outcome, and preinjury mental health was not related to physical disability. The results indicate the importance of defining outcome when attempting to predict rehabilitation progress of burn patients.
