Consensus on a conversation aid for shared decision making with people with intellectual disabilities in the palliative phase

BACKGROUND: Little is known about how to involve people with intellectual disabilities in making decisions about treatment and care in their palliative phase. We aimed to reach a consensus about a shared decision‐making (SDM) conversation aid for people with intellectual disabilities, relatives, and healthcare professionals. METHODS: In a Delphi process, an expert panel of 11 people with intellectual disabilities, 14 relatives, and 65 healthcare professionals completed online questionnaires about the relevance and feasibility of a draft conversation aid. RESULTS: In Round 1, components were rated as (very) relevant by 70–98% of participants (M = 87%). In Round 2, after amending the aid in response to feedback, relevance ratings were 67–97% (M = 90%) and feasibility ratings 66–86% (M = 77%). The final version consists of four themes: who are you; illness/end‐of‐life; making decisions; and evaluating the decision. CONCLUSION: The consensus‐based conversation aid is considered sufficiently relevant and feasible to be implemented in practice.
