The goal of this randomized controlled trial is to investigate the effectiveness of NeuroBot in alleviating anxiety of patients undergoing neurovascular procedures. The main questions it aims to answer are:
Is NeuroBot effective in alleviating anxiety? Is NeuroBot effective in enhancing patients' procedure and disease-related knowledge? Is NeuroBot effective in enhancing patients' compliance to treatment? If there is a comparison group: Researchers will compare with standard perioperative education (control group) to see if there is any difference in results.
Participants will be invited to chat with the artificial intelligence based chatbot "NeuroBot" for 6 weeks, from the date of preoperative clinic visit till 4 weeks after the surgery. The participants are allowed to access the NeuroBot at anytime anywhere, to ask surgery- related questions at their discretion.
The NeuroBot is co-developed by the neurosurgeons, nuerosurgical specialty nurses in Queen Elisabeth Hospital and AI experts from the Hong Kong Polytechnic University and the Chinese University of Hong Kong. The NeuroBot is developed based on the large language model that used machine learning algorithm and generative pretrained transformer model. Vast dataset of neurovascular surgery related information from validated sources, including DynaMed, UpToDate and textbooks were included and used for training of NeuroBot. The precision of the responses generated by NeuroBot was verified by a group of neurosurgical domain experts (neurosurgeons and experienced neurosurgical nurses).

| Measure | Description | Time Frame |
|---|---|---|
| Anxiety | Level of preoperative and postoperative anxiety, measured using State Trait Anxiety Inventory - State scale (6-item Chinese version). There are total of 6-item in the questionnaire, each item uses a 1 to 4 point rating scale. 1: not at all; 2: somewhat; 3: moderate; 4: very much so. The higher the score indicates the greater levels of anxiety | From preoperative (at nurse clinic) to postoperative from 1 week to 4 weeks after surgery |
| Measure | Description | Time Frame |
|---|---|---|
| Knowledge | The level of procedure and disease related knowledge. A 10-item multiple choice questionnaire was developed and validated by neurosurgical experts. It will be used to assess participants' level of knowledge. Each participant will score 1 mark if they correctly answer each question. The higher the score, the higher the level of knowledge. | From preoperative nurse clinic visit to 1 week postoperative |
| Measure | Description | Time Frame |
|---|---|---|
| Perception on the usability of NeuroBot | Conduct qualitative interview for a group of participants in the intervention group to evaluate the usefulness of and satisfaction to the NeuroBot | 4 weeks after surgery |

The control arm will receive standard preoperative education in the preoperative nurse clinic, apart from face-to-face consultation, leaflet will be provided for illustrating the surgical procedure and the disease. For the intervention arm, on top of the standard care as above, they will be additionally provided an artificial intelligence chatbot "NeuroBot" for perioperative support.

| Compliance | Compliance to prescribed treatment including follow-up visit, arranged investigation. The incidence of non-compliance will be traced through reviewing medical records. Each missed follow-up visit and investigation within 1 month after surgery will be counted. Each incidence of missed follow-up visits and investigations will be descriptively reported in both groups | 4 weeks after surgery |
| Readmission | Readmission related to the surgery. The incidence of readmission related to the postoperative complications will be traced in medical record. Number of Participants with readmission will be descriptively reported. | 4 weeks after surgery |
| Postoperative complications | surgery-related postoperative complications. The incidence of surgery-related postoperative complications will be traced in medical record.
