Family Members of Intensive Care Unit Patients

This prospective randomized controlled study aims to evaluate the effect of a QR code-based digital information video on knowledge level and anxiety among family members of intensive care unit (ICU) patients. Participants will be randomly assigned to either a control group receiving routine verbal information or an intervention group receiving routine verbal information plus access to a standardized QR code-based educational video. Knowledge level, anxiety, and satisfaction with information will be assessed at baseline, within 24 hours after the intervention, and 72 hours later. The study will determine whether digital video-based information improves understanding of the ICU environment and reduces anxiety among family members.
