Obtaining patients' medical history using a digital device prior to consultation in primary care: study protocol for a usability and validity study.

Digital tools offer the opportunity to improve patient care. However, it is not self-evident that the medical history taken by digital tools corresponds to the medical history that would be taken in an interview. If simply due to a design flaw patients answer questions about signs and symptoms that indicate possible serious underlying conditions 'wrong', this could have severe consequences. By additionally assessing the app's usability as perceived by a diverse group of patients, potential weaknesses in content, design and navigation can be identified and subsequently improved. This is essential in order to ensure that the app meets the need of different groups of patients. Trial registration German Clinical Trials Register DRKS00026659 , registered Nov 03 2021.
