Variables affecting the decision making of a review panel.

This study was designed to identify the variables that influence a review panel's decision to discharge or detain an involuntary patient. A group of fifty patients consecutively discharged by the review panel of a provincial mental hospital were compared according to thirty-five variables, with a group of forty-five patients consecutively detained by the panel. The variable set included information on the patient's psychiatric history, current hospitalization and treatment as well as ratings of dangerousness, insight and psychopathology, as reflected in the attending physician's case summary prepared for the review panel. The released and detained groups were found to be remarkably similar. They differed on ten of the thirty-five variables measured, but they did not differ on some variables that one would expect to form the basis of the panel's decision, including diagnosis and a history of suicide attempts. On the other hand, when the predictive value of the variable set as a whole was examined using discriminant analysis, the results indicated that there was a substantial amount of predictability to the review panel process. The group membership of 77.5% of the patients can be predicted from only nine variables that contribute to the discriminant function. The results will be of interest to clinicians who deal with review panels on a regular basis and the findings have implications for other practical issues including discharge planning and readiness for community living.
