About this trial
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.

Trial outcomes
Primary outcomes
1
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
Time frame
From preoperative (at nurse clinic) to postoperative from 1 week to 4 weeks after surgerySecondary outcomes
1
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.
Time frame
From preoperative nurse clinic visit to 1 week postoperative2
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
Time frame
4 weeks after surgery3
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.
Time frame
4 weeks after surgery4
Postoperative complications
surgery-related postoperative complications. The incidence of surgery-related postoperative complications will be traced in medical record. Number of Participants with surgery-related postoperative complications will be descriptively reported in both groups
Time frame
4 weeks after surgeryOther outcomes
