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).

Interventions

Intervention model description

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.

Design outcomes

Primary

MeasureTime frameDescription
AnxietyFrom preoperative (at nurse clinic) to postoperative from 1 week to 4 weeks after surgeryLevel 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

MeasureTime frameDescription
KnowledgeFrom preoperative nurse clinic visit to 1 week postoperativeThe 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.
Compliance4 weeks after surgeryCompliance 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
Readmission4 weeks after surgeryReadmission 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.
Postoperative complications4 weeks after surgerysurgery-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

Other

MeasureTime frameDescription
Perception on the usability of NeuroBot4 weeks after surgeryConduct qualitative interview for a group of participants in the intervention group to evaluate the usefulness of and satisfaction to the NeuroBot
