This study was conducted to examine the effects of video-assisted education about the intensive care process on intensive care experiences and anxiety levels of patients scheduled for open-heart surgery.

Research Hypotheses H01: Video-assisted education regarding the intensive care process provided to patients undergoing open heart surgery does not affect their experiences of intensive care.

H1: Video-assisted education regarding the intensive care process provided to patients undergoing open heart surgery does affect their experiences of intensive care.

H02: Video-assisted education regarding the intensive care process provided to patients undergoing open heart surgery does not affect patients' anxiety levels.

H2: Video-assisted education regarding the intensive care process provided to patients undergoing open heart surgery does affect patients' anxiety levels.

The study will include an experimental and a control group. Patients in the experimental group will be administered the Patient Introduction Form, Trait Anxiety and State Anxiety Scales 48 hours before surgery. Then, video-assisted training will be given about the intensive care process, and the state anxiety scale will be applied again 24 hours before the surgery. Twenty-four hours after discharge from the intensive care unit to the clinic, the State Anxiety Scale and Intensive Care Experience Scales will be applied again. These scales will also be applied to patients in the control group who did not receive video-assisted education. Control group patients will not receive any intervention other than standard nursing care.
