Due to the recent growth in the number of Personal Health Records (PHR) as well as the necessity for the development of digital solutions for reliable and accurate documentation of drug allergies, there is a need to explore digital solution as a Digital Allergy Card (DAC). Despite the advantage of using DAC, there are obstacles to taking this solution. While several studies raised privacy concerns as the key barrier to DAC adoption, there is no clear understanding of the variability of these concerns in relation to other factors which may overcome them. Therefore, drawing on situational privacy calculus theory, we propose a mixed-methods approach to assess the trade-off between perceived benefits and privacy concerns in different situations regarding DAC use. This study will provide insights to both academics and practitioners on PHR adoption by the identification of contextual determinants which can influence the adoption of a DAC.
