User Experience Study of the Patient Monitoring Systems Based on Usability Testing and Eye Tracking.

Background/objectives: The patient monitoring system is a critical tool commonly used in hospitals, making it essential to assess caregivers' user requirements and satisfaction with its usability. In intensive care units (ICUs), the usability of these systems is closely linked to the work efficiency of key users, such as nurses, and directly impacts patient safety and treatment outcomes. This study evaluates the usability of patient monitoring systems in intensive care units (ICUs), focusing on user requirements and satisfaction among nurses, the primary users. Usability is directly linked to work efficiency and patient safety, with post-marketing surveillance (PMS) data from overseas, highlighting issues such as unrecognized alarms, leading to worsened patient conditions.

Methods: This study involved 22 ICU nurses who had used the system for over a year, assessing usability through testing, satisfaction surveys, the Health-ITUES, and eye-tracking analysis.

Results: The results showed a high success rate (94%) and positive satisfaction scores (4.15, SD = 0.88), with a Health-ITUES score of 4.13 (SD = 0.78). Eye tracking revealed that some functions, including alarms, were overlooked or not recognized.

Conclusions: Recommendations include improving the interface for alarm messages and recording deletion functions to enhance user satisfaction and patient safety.
