According to the recent literature, approximately 250,000 deaths occur annually in U.S. hospitals resulting from medical error, making it the 3rd leading cause of death. One of the most commonly used devices in hospitals is the Patient Monitor (PM), a device which constantly monitors the vital signs of the patient. In this study, nurses and physicians who regularly interact with patient monitors were surveyed on their perceptions of the usability of the PMs they use on a regular basis. Results indicate that clinicians appeared to be mostly satisfied with the general usability of the monitors, particularly in terms of the information being presented and how it is presented. However, participants pointed out problems with the menu navigation during moments of high stress and the high frequency of false alarms. Also, participants expressed the desire to see additional information displayed on screen.
