Nurses play a key role in healthcare but work in a highly stressful and unfriendly environment. Therefore, many medical institutions have adopted nurse healthcare management information systems for nurses to relieve symptoms of mental stress and even improve their psychological health. The key to the success of these systems depends on how nurses intend to use them. In this study, the moderating effect of nurses' psychological health status on their usage of these systems are discussed. This study used a mail survey method for nurses to obtain 1565 valid samples. The results show that perceived usefulness is insignificant toward the usage intention of nurses with a positive psychological health status, which indicates that this system does not meet the needs of these healthy nurses. Furthermore, perceived ease of use is insignificant toward the usage intention of nurses with a negative psychological health status, which indicates that a negative psychological health status may affect one's behavior due to impatience. This study raises the serious issue that nurses should maintain their psychological health in order to ensure the quality of care for patients. People in various fields are expected to pay attention to the psychological health status of nurses and create a win-win situation for both patients and nurses.
