Psychiatric wards have long been considered one of the most challenging areas in hospital management. Patients often have unique conditions and unpredictable behaviors. Traditional methods—manual rounds and paper-based records—are labor-intensive and prone to errors. In recent years, as hospitals increasingly embrace digital transformation, RFID (Radio Frequency Identification) technology has been introduced in psychiatric settings, offering new tools to improve patient safety and maintain order. 1. Challenges in Psychiatric Ward Management Patients in psychiatric wards often suffer from cognitive disorders, impulsivity, or even aggression. Some are at risk of self-harm, suicide, or attempting to leave the ward unsupervised. These factors make strict identity verification and movement monitoring essential. In practice, incidents such as medication errors, patients entering restricted areas, or even going missing occur more often than in general wards. Once an incident occurs, it can be difficult to trace the exact timeline and assign responsibility. At the same time, the burden on psychiatric nurses is considerable. Night shifts, frequent identity checks, and managing visitors or caregivers consume time and energy, increasing the likelihood of human error. How to ensure safety while respecting patient dignity remains a key concern for administrators. 2. How RFID Is Changing the Game RFID uses radio waves to identify and track tags attached to objects or individuals. Unlike barcode systems, RFID works without direct line-of-sight and can read multiple tags simultaneously, making it ideal for complex environments. In psychiatric wards, RFID technology is primarily applied in the following areas: Accurate Identity Verification and Medication Safety Each patient wears an RFID wristband encoded with their personal and medical information. Before administering medication, nurses scan the wristband with a handheld device. The system automatically verifies the match, helping prevent medication errors due to mistaken identity or manual entry mistakes. Real-Time Location Tracking for Enhanced Safety RFID readers installed at key locations—such as hallways, restrooms, treatment rooms, and entrances—can track patient movements. If a patient remains in a restricted area for too long or frequently leaves their room at night, the system can send an alert to the nursing station for timely intervention. Restricted Zone Alerts for High-Risk Patients For patients with a history of escape attempts or self-harm, certain areas can be marked as "off-limits." If these patients approach those areas, the system will trigger an alert, allowing staff to take preventive action. Visitor and Caregiver Management Temporary RFID cards or lanyards can be issued to caregivers and visitors, allowing the system to log their entry times and track which zones they access. This improves overall ward security and traceability. Behavioral Data to Support Clinical Judgment Beyond real-tim...
