Abstract

Background: 

Trials of interventions to prevent or treat delirium in adults in an acute hospital setting report heterogeneous outcomes. Our objective was to develop international consensus among key stakeholders for a core outcome set (COS) for future trials of interventions to prevent and/or treat delirium in adults with an acute care hospital admission and not admitted to an intensive care unit.

Methods: 

A rigorous COS development process was used including a systematic review, qualitative interviews, modified Delphi consensus process, and in-person consensus using nominal group technique (registration http://www.comet- initiative.org/studies/details/796).Participants in qualitative interviews were delirium survivors or family members. Participants in consensus methodscomprised international representatives from three stakeholder groups: researchers, clinicians, and delirium survivorsand family members. 


Results: 

Item generation identified 8 delirium-specific outcomes and 71 other outcomes from 183 studies, and 30outcomes from 18 qualitative interviews, including 2 that were not extracted from the systematic review. Deduplication of outcomes and formal consensus processes involving 110 experts including researchers (N = 32),clinicians (N = 63), and delirium survivors and family members (N = 15) resulted in a COS comprising 6 outcomes: delirium occurrence and reoccurrence, delirium severity, delirium duration, cognition, emotional distress, and health-related quality of life. Study limitations included exclusion of non-English studies and stakeholders and small representation of delirium survivors/family at the in-person consensus meeting.
