Effect of Leaflet-Based Intervention on Family Members of Terminally Ill Patients with Cancer Having Delirium: Historical Control Study

OBJECTIVE:We aimed to assess leaflet-based intervention effects on family-perceived distress, the need for improvements in professional care for delirium, and family knowledge of delirium causes.METHODS:Leaflet-based intervention effects were assessed by comparing responses of family members given in the leaflet with those of a historical control group not receiving it.RESULTS:Knowledge of delirium causes was significantly more likely to be correct in the intervention group, while there were no significant differences in family-perceived distress or need for improvements in professional care for delirium between the 2 groups.CONCLUSIONS:The leaflet providing information about delirium improved family knowledge of cancer delirium. To relieve family distress, a comprehensive program focused mainly on psychological aspects, in addition to educational intervention with this leaflet, is a promising strategy.
