Study Design: A qualitative study involving focus group work with 10 participants was conducted. Interviews with each focus group were held twice: session 1 explored the lived experience of patients with OLP, and session 2 allowed patients to review a summary of the outcome domains used in the OLP literature to date. The discussions were recorded, transcribed verbatim, and analyzed using framework analysis. Results: In session 1, 4 themes and 8 sub-themes emerged from the data analysis. An additional outcome, ‘knowledge of family and friends,’ was suggested in session 2. Conclusions: We have gained valuable insight into the lived experience of patients with OLP via this qualitative study. To our knowledge, this study is the first to explore the patient perspective on what should be measured in clinical trials on OLP, highlighting an important additional suggested outcome. This additional outcome will be voted upon in a consensus process to determine a minimum COS for OLPeng© 2023 The Author(s). Published by Elsevier Inc.
