Randomized trial of psychotropic medication information leaflets for people with intellectual disability.

People with intellectual disability (ID), like other patient groups, are known to have a limited knowledge of medication. Leaflets are seen as an appropriate means of providing patient information. To test the hypothesis that medication information leaflets would improve the knowledge and care of the target group, the present authors designed a randomized trial and planned to do subgroup analyses where appropriate. The participants were individually randomized to two groups. A control group was given verbal medication information by their nurse or psychiatrist, and a study group was given specifically designed leaflets in addition to verbal information. The present authors recruited 54 people with mild to moderate ID and mental illness, aged 18 years and older, who were taking psychiatric medications. Questionnaires administered by a blind interviewer recorded outcomes such as medication knowledge and satisfaction at two time points. The participants with mild ID in the leaflet group had significantly reduced medication knowledge and understanding. There were no significant differences in satisfaction with clinicians and medication. Patient information leaflets may confuse people with mild ID in the short term. Other patient groups with cognitive deficits may have similar outcomes. Evaluation of outcomes of health education initiatives is important.
