BaiXiaoAi AI Companion for Cancer Patient Follow-up

This is a prospective, single-center, exploratory clinical study aiming to comprehensively assess the diagnostic accuracy, user engagement efficacy, and subjective user experience of the BaiXiaoAi Companion AI system in the context of clinical patient management.

Following the voluntary signing of the informed consent document and formal enrollment into the study cohort, each participant will be assigned to a dedicated WeChat group adopting a "Doctor-Nurse-Patient-AI" quadruple collaborative model. Within this closed communication platform, the BaiXiaoAi Companion AI is programmed to perform two core functions: first, it delivers real-time, contextually tailored responses to patients' inquiries, symptom descriptions, and daily health-related communications shared within the group; second, it proactively disseminates personalized, evidence-based content covering disease-specific management protocols, medication adherence guidance, lifestyle modification recommendations, and targeted patient education materials. These interventions are designed to facilitate seamless interaction between medical providers and patients while leveraging AI-driven tools to augment the continuity of care outside of traditional clinical settings.
