Brief Summary

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.

Conditions

Anxiety; Patient Compliance; Knowledge

Keywords

Chatbot; NeuroBot; Perioperative education; Neurovascular surgery

Outcome Measures

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

  From preoperative (at nurse clinic) to postoperative from 1 week to 4 weeks after surgery

Secondary Outcomes (4)

• Knowledge

  From preoperative nurse clinic visit to 1 week postoperative

• Compliance

  4 weeks after surgery

• Readmission

  4 weeks after surgery

• Postoperative complications

  4 weeks after surgery

Other Outcomes (1)

• Perception on the usability of NeuroBot

  4 weeks after surgery
