Family Automated Voice Reorientation Study

This randomized clinical trial tests a cognitive reorientation intervention to prevent delirium in the intensive care unit using scripted audio messages, recorded by the patient's family and played at hourly intervals during daytime hours, to provide information about the ICU environment to the patient (the Family Automated Voice Reorientation intervention, FAVoR). The investigators hypothesize that providing ongoing orientation to the ICU environment through recorded audio messages in a voice familiar to the patient will enable the patient to more accurately interpret the environment and reduce risk of delirium. Increasing awareness of daytime by cuing patients during waking hours may also improve day/night orientation, nighttime sleep/rest, and further reduce risk of delirium.
