This prospective, randomized controlled trial aims to evaluate the efficacy of an Internet-Based, Family-Participatory Early Rehabilitation (IFPER) model compared to standard care for critically ill patients in the Intensive Care Unit (ICU). The study will determine if the IFPER model, which is based on a structured "7P Rehabilitation" framework, can improve sleep quality, reduce the perception of critical illness-related social stigma, and alleviate procedural pain.

Critically ill patients often suffer from Post-Intensive Care Syndrome (PICS), which includes severe sleep disturbances, pain, and psychological issues like social stigma. While family involvement in care is known to be beneficial, structured, technology-supported models are scarce. This study was designed to address this gap by testing a novel IFPER model. A total of 204 adult patients admitted to the ICU were randomized to either the IFPER group or a standard care group. The IFPER intervention involves trained family members using a mobile application to deliver a structured, multi-component rehabilitation program based on the "7P Rehabilitation Model" (Position Management, Pain \& Sedation, Physiotherapeutics, Pulmonary Rehabilitation, Psychological Rehabilitation, Performance Rebuilding, Purpose \& Belonging). The standard care group received routine ICU care. The study hypothesizes that this structured, family-centered approach will lead to significantly better outcomes in sleep, stigma perception, and pain management compared to standard care alone.
