Formatted abstract
A hospital ward is often a noisy and busy environment to work in, particularly when hospital workers are required to monitor multiple patients. As a result, clinicians can experience alarm fatigue and this can lead to poor health outcomes. Auditory displays have been shown to reduce constraints on attention, providing a solution to the alarm problem. However researchers have not examined the effectiveness of an auditory display for multiple patient monitoring. Accordingly, in a series of two experiments we examined if people can identify the heart rate and oxygen saturation levels of multiple neonates through a sequence of earcons. Experiment 1 tested what effect the number of patients monitored through the display and the number of patients that entered an abnormal state had on identification accuracy. Results showed that a larger number of patients in the sequence did not affect identification accuracy; however, identification accuracy was reduced when participants were required to identify the vital signs of more than one abnormal patient in the sequence. In Experiment 2, the time interval between sounds was increased to see if this improved performance. Results showed that participants identified multiple patients’ vital signs more accurately with a long time interval between earcons, compared to a short time interval. Future research is required to refine the multiple patient auditory display and test its use in clinical settings. However the current study demonstrates strong potential for the implementation of a multiple patient monitoring auditory display in a hospital, which could be beneficial to both clinicians and patients.
