VoiceLove Digital Therapy for Delirium in the ICU

VoiceLove digital therapy includes voice recordings of the participant's loved one delivered at the bedside via a smartphone attached to the bed. The VoiceLove digital therapy will be delivered in the morning and in the evening and will play for 20-25 minutes each session.

Participants will have a pre-operative visit, 3 consecutive intervention visits with vital signs assessment, 7 days of assessments of Confusion Assessment Methods (CAM)-ICU (morning and evening), and 7 days of a Richmond Agitation-Sedation Scale assessment. The participant will provide an assessment of the acceptability of the VoiceLove digital therapy using a system usability scale score at the end of their participation in the study.
