Seclusion: the quest to determine effectiveness.

1. The decision whether to use seclusion as an intervention often is based on emotional argument and anecdotal evidence. Little research examining effectiveness as an intervention exists. 2. This study compares two units, one of which uses seclusion, around the parameters of resolution time of emergencies, levels of PRN medication used, and the nurses' perception of the effectiveness of used interventions. 3. Results of the study indicate that around some parameters, seclusion may be more effective than alternate interventions. More research is needed.
