Applying Human Factors Methods to Inform the Implementation of a Novel Medical Device

Abstract

Usability testing was performed to identify usability problems with a medical device designed to detect respiratory depression. Personnel lacking formal human factors training developed and implemented the test plan. Quantitative usability test analysis involved measuring task completion time, success rate, and usability issue frequency. Qualitative data was collected via visual observations of the participants. Significant usability problems were identified with the following tasks: entering patient information, opening alarm settings, and adjusting alarms. The test results were used to improve the hospital’s clinical training.
