AI-LLM Communication Aid in Prostate Cancer Care (AI-CAP）

The goal of this clinical trial is to evaluate the efficacy of large language model (LLM)-assisted communication on psychological distress alleviation and healthcare efficiency improvement in prostate cancer patients. The main questions it aims to answer are: Does LLM-assisted communication reduce preoperative anxiety and negative emotion more effectively than standard care? Can LLM-assisted communication decrease clinician workload while maintaining communication quality? Researchers will compare the intervention group (LLM-assisted communication) with the control group (standard communication) to see: Whether LLM-assisted communication has greater reductions in patients' emotional distress scales and physiological stress metrics. How it impacts clinician workload and communication time. Participants will: Undergo baseline assessments before communication, including a range of emotional scales and physiological metrics. Receive clinician-reviewed LLM-generated materials and/or standard communication before surgery. Complete assessments after preoperative communication.
