Study Overview
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.
Detailed Description
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).

Outcomes
Primary Outcomes
Anxiety
Time Frame: From preoperative (at nurse clinic) to postoperative from 1 week to 4 weeks after surgery
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
Secondary Outcomes
- Postoperative complications(4 weeks after surgery)
- Knowledge(From preoperative nurse clinic visit to 1 week postoperative)
- Compliance(4 weeks after surgery)
- Readmission(4 weeks after surgery)
