May 12, 2020 – Mobile App Display Size vs Usability and Safety for Retrieving Medical Records – Simon Minshall, University of Victoria
While mobile device use by physicians increases, there is an increased risk that errors committed while using mobile devices can lead to harm. This mixed-method study evaluates the effects of screen size on clinical users’ perceptions of medical application usability and safety when interfacing to critical patient information. There is an association between screen size and the perceived safety of the handheld device. The iPad was perceived to be safer to use in clinical practice. Participants preferred the iPad because of the larger size, not because they thought it was safer or easier to use. The iPhone was preferred for its portability and its usefulness was perceived to increase with greater distance from the point of care.
