Development and pilot testing of the revised Patients' Attitudes Towards Deprescribing questionnaire for people with cognitive impairment.

Objectives: (i) To develop a version of the revised Patients' Attitude Towards Deprescribing (rPATD) questionnaire for people with mild cognitive impairment (MCI) and mild-to-moderate dementia (rPATDcog); and (ii) to capture the beliefs and attitudes of this population and their carers about deprescribing through a pilot study.

Methods: First, the rPATDcog was modified from the rPATD and tested in a small group of participants with MCI or mild dementia, and then, we conducted a pilot study of the rPATDcog and the carers' rPATD.

Results: Twenty-one participants with cognitive impairment and 11 carer participants (forming dyads) participated in this study. Eighty-one per cent (17/21) of participants said that they would stop one or more of their medications if their doctor said it was possible. There was an excellent agreement of corresponding questions between dyads.

Conclusion: The rPATDcog was feasible to administer in this study. Further work is required to provide generalisable results and determine utility in practice.
