This study was planned to be a randomized controlled experimental study to determine the effect of patient education and family interview practices using virtual reality on stress intensity, anxiety and information need levels, sleep quality and satisfaction with the preparation process for surgery in cholecystectomy patients. The main questions it aims to answer are:

• Is there a significant difference in stress intensity, anxiety, and information need levels between patients who received and did not receive patient education with VR glasses in the ward before cholecystectomy surgery?
• Is there a significant difference in stress intensity and anxiety levels between patients who received and did not receive video family interviews with VR glasses in the operative waiting area before cholecystectomy surgery?
• Is there a significant difference in stress intensity, anxiety, and sleep quality levels at discharge of groups that received different VR interventions?
• What is the postoperative sleep quality of patients with low preoperative anxiety levels?
• What is the satisfaction of patients who received VR with the surgery preparation process? The patients participating in the study will be numbered according to the order of hospitalization and assigned to one of the control, education, education+interview groups in accordance with the randomization list. Face-to-face communication will be established with each patient in the ward on the day of hospitalization, in the preoperative waiting area when they come to the operating room and in the ward on the day of discharge. Depending on the groups in which the patients are included, they will be shown an educational video using virtual reality goggles and/or will be allowed to meet with their families. No application will be made to the control group and the ward routine will continue.

Virtual reality (VR) is an interactive field that offers sensory experiences such as three-dimensional vision, touch and hearing, allowing people to dive into the virtual world and feel that they are in a different environment. In healthcare services, it is seen that the effect of virtual reality technology on various patient outcomes has been examined by watching nature videos, training, exercise applications, museum tours with music and games. This study was planned to be a randomized controlled experimental study to determine the effect of patient education and family interview practices using virtual reality on stress intensity, anxiety and information need levels, sleep quality and satisfaction with the preparation process for surgery in cholecystectomy patients. G*Power (v3.1.9.7) program was used to determine the sample size in the study and considering possible losses, it was decided to include a total of 60 patients, 20 in each group.

During the data collection process, it is planned to include a total of six patients in the preliminary pilot application, two from the education group, two from the education+interview group, and two from the control group, for the comprehensibility and usability of the forms. Patients who have undergone preliminary application will not be included in the study. The patients participating in the study will be numbered according to the order of hospitalization and assigned to one of the control, education, education+interview groups in accordance with the randomization list. Face-to-face communication will be established with each patient in the ward on the day of hospitalization, in the preoperative waiting area when they come to the operating room and in the ward on the day of discharge. The first interview with the patients will be held in the patient room in the ward. During this interview, the patients will be invited to the study and the research will be explained. Informed voluntary consent will be obtained from the patients who agree to participate in the study. Depending on the groups in which the patients are included, they will be shown an educational video using virtual reality goggles and/or will be allowed to meet with their families. Data will be collected with the Introductory Information Form, Visual Analog Scale for Stress, Amsterdam Preoperative Anxiety and Information Scale (APAIS), Richards Campbell Sleep Scale (RCBS), Virtual Reality Evaluation Form and Visual Analog Scale for Satisfaction. Oculus Quest 2 VR glasses will be used as a virtual reality application tool in the study.

The virtual family meeting will be initiated through the meeting link shared with the patients relative, and VR glasses and computer connection will be provided with the BigScreen computer application. Patients have a video call with their family in a 360° designed home environment. The conversations are easily transmitted thanks to the internal speaker and microphone in the VR glasses. In order to adjust the patients viewing angle, to provide guidance when needed, and to monitor communication, the image the patient sees in the VR glasses will be monitored with the Meta Quest program installed on the researchers mobile phone. The training video is a 2-3 minute animated video with visual and auditory elements and includes the ward nurse coming to the newly admitted patient in a patient room and giving information. In order to prevent infection, after each patients use, the supporting pads, straps, and lenses of the virtual reality glasses will be disinfected with cleaner and allowed to dry. It will be kept in its own box and offered to the other patients use.

In the first phase of the study with the patients in the control group, the data collection tools including the Introductory Information Form, the Visual Analog Scale for Stress, the Amsterdam Preoperative Anxiety and Information Scale (APAIS) and the Richard-Campbell Sleep Scale (RCS) will be filled in on the day of admission. No intervention will be applied to the patients and routine procedures will continue. After 30 minutes, the patient will be asked to fill in the Visual Analog Scale for Stress and the Amsterdam Preoperative Anxiety and Information Scale (APAIS) again. In the second phase of the study, when the patients are taken to the preoperative waiting area of the operating room, the data collection tools including the Visual Analog Scale for Stress and the Amsterdam Preoperative Anxiety and Information Scale (APAIS) will be filled in. At the end of the period in which the patient waits to be taken to the operation, the patient will be asked to fill in the Visual Analog Scale for Stress and the Amsterdam Preoperative Anxiety and Information Scale (APAIS) again. In the final phase of the study, the Stress visual analog scale, Amsterdam preoperative anxiety and information scale (APAIS), Richard-Campbell sleep scale (RCUS) and Satisfaction visual analog scale will be filled in the patient room before discharge on the morning of the first postoperative day.

In the first phase of the study, the patients in the patient education group will first fill out the data collection tools including the Introductory Information Form, Stress visual analog scale, Amsterdam preoperative anxiety and information scale (APAIS) and Richard-Campbell sleep scale (RCUS) on the day of admission. Then, a patient education video about laparoscopic cholecystectomy operation will be watched with virtual reality glasses. 30 minutes after watching the education video, patients will be asked to fill out the Stress visual analog scale and Amsterdam preoperative anxiety and information scale (APAIS) again. In the second phase of the study, when the patients are taken to the preoperative waiting area of the operating room, the Stress visual analog scale and Amsterdam preoperative anxiety and information scale (APAIS) will be filled in the data collection tools including the Stress visual analog scale and Amsterdam preoperative anxiety and information scale (APAIS). At the end of the waiting period for the patient to be taken to the operation, they will be asked to fill out the Stress Visual Analog Scale and Amsterdam Preoperative Anxiety and Information Scale (APAIS) again. In the last stage of the study, on the morning of the first post-operative day, before discharge, the patient will be asked to fill out the data collection forms including the Stress Visual Analog Scale, Amsterdam Preoperative Anxiety and Information Scale (APAIS), Richard-Campbell Sleep Scale (RCUS), Virtual Reality Evaluation Form and Satisfaction Visual Analog Scale in the patient room.

In the first stage of the study, the patients in the Education + Interview group will first fill out the data collection tools including the Introductory Information Form, Stress Visual Analog Scale, Amsterdam Preoperative Anxiety and Information Scale (APAIS) and Richard-Campbell Sleep Scale (RCUS) on the day of admission. Then, a patient education video regarding laparoscopic cholecystectomy operation will be watched with virtual reality glasses. After watching the training video, patients will be asked to fill out the Stress Visual Analog Scale and Amsterdam Preoperative Anxiety and Information Scale (APAIS) again 30 minutes later. In the second phase of the study, when patients are taken to the preoperative waiting area, data collection tools including the Stress Visual Analog Scale and Amsterdam Preoperative Anxiety and Information Scale (APAIS) will be filled out. After the patient is put on virtual reality glasses and his/her vision is adjusted, a video family interview will be initiated. After the 5-minute virtual visit with the patients relative(s), the interview will be concluded and the Stress Visual Analog Scale, Amsterdam Preoperative Anxiety and Information Scale (APAIS) will be filled out again. In the last phase of the study, data collection forms including the Stress Visual Analog Scale, Amsterdam Preoperative Anxiety and Information Scale (APAIS), Richard-Campbell Sleep Scale (RCUS), Virtual Reality Evaluation Form and Satisfaction Visual Analog Scale will be filled out in the patients room before discharge on the morning of the first postoperative day.
