Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this clinical trial is to evaluate whether Large Language Models (LLMs) combined with an optimized care program can effectively manage Post-Intensive Care Syndrome (PICS) in adult ICU survivors (aged ≥18 years) discharged from a tertiary hospital in China. The main questions it aims to answer are:

* Does the intervention (optimized program + LLMs) improve physical, psychological, cognitive, and social function recovery compared to standard care or the optimized program alone?
* How do patients experience and perceive the utility of LLMs in PICS self-management during recovery?

Researchers will compare three groups:

1. Group A (routine care)
2. Group B (optimized program without LLMs)
3. Group C (optimized program + LLMs) to see if adding LLMs significantly enhances PICS symptom management, patient self-efficacy, and quality of life over 6 months post-discharge.

Participants will:

* Install and use the Kimi Smart Assistant LLM (Group C only) for health queries under nurse supervision.
* Complete standardized questionnaires at discharge (baseline), 7 days, 1 month, 3 months, and 6 months post-discharge:

* PICS Symptom Questionnaire (PICSQ)
* Pittsburgh Sleep Quality Index (PSQI)
* Anxiety (GAD-7) and Depression (PHQ-9) scales
* Self-Management Ability Scale (AHSMSRS)
* Attend semi-structured interviews (Group C only) at 3 and 6 months to share experiences with LLM use.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Routine Care Group

Participants receive standard post-ICU follow-up care according to hospital protocols . This includes routine health assessments and general rehabilitation guidance at designated intervals (discharge, 7 days, 1/3/6 months post-discharge). No structured PICS management program or AI technology is provided.

Group Type OTHER

Routine Care

Intervention Type BEHAVIORAL

Participants receive standard post-ICU follow-up care according to hospital protocols . This includes routine health assessments and general rehabilitation guidance at designated intervals (discharge, 1/3/6 months post-discharge). No structured PICS management program or AI technology is provided.

Optimized Program Group

Participants receive an evidence-based, optimized PICS management program developed using the Health Promotion Model (HPM). This includes personalized rehabilitation plans, psychological support, and education tailored to PICS symptoms. Interventions are delivered by clinical staff at discharge, 7 days, and 1/3/6 months post-discharge. No AI/LLM technology is used.

Group Type OTHER

Health Promotion Model-Based Optimized Program

Intervention Type BEHAVIORAL

An evidence-based, multidisciplinary rehabilitation protocol for Post-Intensive Care Syndrome (PICS) management, developed using the Health Promotion Model (HPM). It includes:

Personalized rehabilitation plans addressing physical, cognitive, and psychological recovery.

Structured follow-up at discharge, 1/3/6 months post-discharge. Components: Physical function training, cognitive exercises, anxiety/depression coping strategies, and sleep hygiene education.

Delivery: Clinician-guided (no AI/technology involved). Developed via literature review and validated by ICU physicians and nursing experts .

LLM-Enhanced Optimized Program

Intervention Type BEHAVIORAL

Combines the HPM-Based Optimized Program with Large Language Model (LLM) technology for dynamic personalization:

AI-generated rehabilitation plans: ChatGPT-4 synthesizes patient data (baseline + follow-ups) to create/update monthly plans, reviewed by a multidisciplinary expert team.

Patient-facing LLM tool: "Kimi Smart Assistant" installed for daily health queries under strict safety protocols (all outputs validated by nurses via WeChat).

Phased implementation:

Pre-discharge: LLM training + baseline plan generation. 1/3/6 months: Plan updates + outcome tracking. 3/6 months: Semi-structured interviews on LLM experience. Includes LLM usage guidelines and expert validation safeguards .

Optimized Program + LLMs Group

Participants receive the same optimized PICS program as Group B, enhanced with Large Language Models (LLMs). Key components:

Personalized AI-generated plans: ChatGPT-4 synthesizes patient data (baseline + follow-ups) to create monthly rehabilitation plans, reviewed by a multidisciplinary expert team.

LLM access: Installation of "Kimi Smart Assistant" for daily health queries. Safety protocols: Patients must validate LLM advice with nurses via WeChat before use .

Phased intervention:

Pre-discharge: LLM training + baseline plan generation.

1 month: Plan updates based on new data. 3/6 months: Plan updates + semi-structured interviews about LLM experience.
