DescriptionThe high workload has been identified as one of the main stressors of intensive care unit nurses; this factor has been linked to increased length of stay and mortality rate. Digitalization of ICUs has transformed the content of nursing activities more into cognitive load and made nurses susceptible to medical errors. This study estimates workload via the correlation between ocular metrics and workload. We employed Tobii Pro Glasses 2 and Empatica E4 to capture physiological responses of 15 ICU nurses to assess mental workload (day with night shifts and incoming and outgoing nurses) and to study the effect of stress on visual search.
We found no significant difference between the mental workload of day and night shift nurses; incoming nurses' load was higher than outgoing nurses and stress made the visual search more random. The outcomes disclosed the potential of ocular measures in the development of a real-time supporting system.
