  Routinely collected clinical patient data posits a valuable resource for
data-driven medical innovation. Such secondary data use for medical research
purposes is dependent on the patient's consent. To gain an understanding of the
patients' values and needs regarding medical data donations, we developed a
participatory workshop method, integrating approaches from value-sensitive and
reflective design to explore patients' values and translate them into
hypothetical, ideal design solutions. The data gathered in the workshop are
used to derive practicable design requirements for patient-oriented data
donation technologies. In this paper, we introduce the workshop process and
evaluate its application.
