Objective To assess which information about microtia and the possible reconstructive options health care providers (HCPs), patients and parents believe should be included in a patient decision aid (PtDA). Design A mixed-methods study comprised of an online survey of HCPs and focus group discussions with patients and parents. Participants Survey respondents were members of the International Society for Auricular Reconstruction (ISAR). Focus group participants were patients with microtia and their parents, recruited through the microtia outpatient clinic at Amsterdam UMC, and through a Dutch patient organization for cleft and craniofacial conditions. Methods An online, investigator-made survey was sent to ISAR members in December 2021. Semi-structured focus group discussions were held in February 2022. Quantitative results were summarized, and qualitative results were thematically grouped. Results Thirty-two HCPs responded to the survey (response rate 41%). Most respondents (n = 24) were plastic surgeons, who had a median of 15 years of experience (IQR: 7-23 years). Two focus groups were held with a total of five patients and two parents. HCPs, patients and parents generally agreed on the information needed in a PtDA, emphasizing the importance of realistic expectation management. Patients and parents also considered psychosocial and functional outcomes, patient experiences, as well as patients’ involvement in decision-making important. Conclusions A PtDA for microtia reconstruction should target all patients with microtia, and include information on at least technique-related information, expected esthetic results, possible adverse effects, psychosocial and functional outcomes and patient experiences. Preference eliciting questions should be developed for both pediatric patients and their parents.
