New app aims to ease mental health struggles after ICU stays

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Other complex needs anticipated that could interfere with the ability to complete study procedures. Examples include: * Anticipated disruptive travel * Inability to use mobile app * Anticipated unstable living situation 4. Anticipated or actual discharge to a location other than independent in a home setting (e.g., nursing home, long-term acute care facility, inpatient rehabilitation facility, home hospice) 5.

Previously enrolled in the trial Exclusion criteria present after hospital discharge (i.e., at T1 Data Collection conducted at the time of arrival home from the hospital) 1. Failure to randomize within 14 days from planned start date (planned start date is within 3 days post-discharge from the hospital to home to accommodate weekends) 2.
