VR-based Informed Consent
Conditions
Brief summary
The goal of this randomized controlled trial is to evaluate benefits of VR (virtual reality)-based patient informed consent in neurosurgery regarding subjective patient comprehension, patient-doctor relationship and anxiety.
Detailed description
Additionally, the investigators aim to assess the cost-benefit radio as well as feasibility in a clinical routine setting. Considering the increasing patient participation in decision-making, VR could lead to better understanding of complex surgical procedures, improving the perioperative process for both, patient and surgeon, and reduce anxiety.
Interventions
The intervention group will be the on receiving VR-based patient informed consent. One surgeon from the study team will be guiding the patient through their VR model first with demonstration of the technology and the model, afterwards the patient will be enabled to use the VR system by themselves. During the whole process the patient will be able to ask questions. Depending on the planned surgery, the surgical approach as well important anatomical structures will be explained.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Comparison of intensity of anxiety between intervention and control group | one time assessment at day 1 | Comparison of intensity of physical and cognitive anxiety symptoms will be assessed by the questionnaire Beck Anxiety Inventory (BAI). This questionnaire consists of 21 self-reported items (four-point scale). min score: 39 (minimal anxiety level) max score:174 (severe anxiety) |
| Comparison of patient doctor relationship between intervention and control group | one time assessment at day 1 | Comparison of patient doctor relationship will be assessed by PDRQ9 (patient-doctor relationship questionnaire). The questionnaire is a 9-item scale that assesses patients' perception of the relationship with the physician. Items are scored on a 5-point Likert scale ranging from 'not at all appropriate' to 'totally appropriate'. Raw sum scores range from 9 to 45, with higher scores indicating that the patient's perception of the patient-doctor relationship is more favorable. |
