Objective To construct a family participatory multisensory stimulation program for management of delirium for ICU adults patients, and to provide reference for non-drug management of delirium. Methods Through literature review, and semi-structured interviews with ICU medical staff and family members of ICU patients, a pool of items were constructed. The 2 rounds of Delphi expert consultation were conducted in 20 experts .Results The response rate for each round of consultation reached 100%. The expert authority coefficient was 0.837 and 0.880 respectively for the first and the second round. The finalized family participatory multisensory stimulus scheme consisted of 5 first-level indexes(stimulus preparation, visual, auditory, kinesthetic and tactile stimuli), 15 second-level items and 44 third-level items. Conclusion The family participatory multisensory stimulation program constructed is reliable, and can be added to non-drug management of delirium in ICU patients.
