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.
