Exploring the Use of AI-Assisted Video Monitoring to Predict Accidental Events in ICU Patients

This study aims to improve the safety and care of patients in the Intensive Care Unit (ICU) by using artificial intelligence (AI) to analyze video monitoring. ICU patients often face serious risks such as delirium, accidental removal of breathing tubes or lines, and sleep problems. These events can lead to medical emergencies, longer ICU stays, higher costs, and worse outcomes. To address these challenges, we will place a small video camera above each ICU bed. The camera will record patient movements, body activity, and sleep patterns. At the same time, routine medical monitors will record heart rate, blood oxygen levels, and other vital signs. Noise levels in the room will also be measured. All these data help us understand the patient's behavior and condition more accurately. The video recording does not involve extra treatment or additional procedures. All data are collected passively and safely. Patient privacy is strictly protected: the system will blur faces or replace them with digital avatars, and any information that could identify the patient or the environment will be masked. All videos are stored securely inside the hospital and are processed only after privacy protection. Using these recordings, an AI model will be trained to recognize early warning signs of dangerous situations. For example, the system may detect early movements that suggest the patient is becoming agitated, confused, or trying to remove medical tubes. It may also identify severe sleep disturbance that may lead to delirium. If the AI can recognize these early changes, medical staff can intervene sooner and prevent harm. About 300 patients from Fudan University Zhongshan Hospital will participate. Participation is voluntary. Patients or families will sign an informed consent form before being enrolled. The study has three stages: Screening - understanding the study and signing consent. Data collection - video and medical monitor data are collected during the ICU stay. Follow-up -
