Design of E-Health Application to Enhance Health Information Quality: the Case of a Digital Allergy Card.

Information quality is a crucial requirement in healthcare because physicians and patients need structured, accessible, reliable, accurate and secure information for optimal patient treatment. Despite this crucial character, studies on information quality remain limited because they focus on evaluating and suggesting partial solutions after implementing e-health applications containing the information. They often neglect the design phase, where many problems could be avoided. This study seeks to address allergy information quality problems during a digital allergy card design through action design research. The evaluation phase was conducted through interviews with patients and physicians. We used thematic analysis to identify the different codes linked to the dimensions of information quality. We deduced five design principles. In addition to the implications of design principles for both practice and research, this paper highlights the importance of considering the dimensions of information quality individually or combining each other to build the e-health application features.
