World Workshop on Oral Medicine VIII: Development of a core outcome set for oral lichen planus: a consensus study

Objective: A core outcome set (COS) is the minimum agreed-on data set required to be measured in interventional trials. To date, there is no COS for oral lichen planus (OLP). This study describes the final consensus project that brought together the results of the previous stages of the project to develop the COS for OLP.

Study design: The consensus process followed the Core Outcome Measures in Effectiveness Trials guidelines and involved the agreement of relevant stakeholders, including patients with OLP. Delphi-style clicker sessions were conducted at the World Workshop on Oral Medicine VIII and the 2022 American Academy of Oral Medicine Annual Conference. Attendees were asked to rate the importance of 15 outcome domains previously identified from a systematic review of interventional studies of OLP and a qualitative study of OLP patients. In a subsequent step, a group of OLP patients rated the domains. A further round of interactive consensus led to the final COS.

Results: The consensus processes led to a COS of 11 outcome domains to be measured in future trials on OLP.

Conclusion: The COS developed by consensus will help reduce the heterogeneity of outcomes measured in interventional trials. This will allow future pooling of outcomes and data for meta-analyses. This project showed the effectiveness of a methodology that could be used for future COS development.

- Survey
- Systematic review

The COS will be developed using methodology reflecting the four steps outlined by the Core Outcome Measures in Effectiveness Trials (COMET) Initiative. Potential outcomes will be initially identified from a systematic review of the literature. Further outcomes of importance will be determined via qualitative methods, engaging with key stakeholders including patients, clinicians, researchers, Federal healthcare and funding agencies, and industry. The outcomes identified will subsequently be reviewed using a Delphi survey to select a COS. A face-to-face meeting with representatives from all stakeholders will be held to finalise the COS for OLP. This work will be undertaken under the direction of the World Workshop on Oral Medicine.
