Involving people with lived experience in developing a core outcome set for implant dentistry research. The Implant Dentistry-Core Outcomes Sets and Measures (ID-COSM) project.

AIMS

The aims of this project were to establish the outcomes for dental implant research that are important to people with lived experience (PWLE) and to achieve consensus with those developed by dental professionals (DPs) for a core outcome set (COS). This paper reports the process, outcomes and experiences of involving PWLE in developing a COS for dental implant research: the Implant Dentistry Core Outcome Sets and Measures project.

MATERIALS AND METHODS

Overall methods were guided by the Core Outcome Set Measures in Effectiveness Trials (COMET) initiative. Initial outcome identification was achieved from focus groups with PWLE employing calibrated methods across two low-middle-income countries (China and Malaysia) and two high-income countries (Spain and the United Kingdom). Following consolidation of the results, the outcomes were incorporated into a three-stage Delphi process with PWLE participation. Finally, consensus between PWLE and DPs was achieved using a mixed live and recorded platform. The experiences of PWLE involvement in the process was also evaluated.

RESULTS

Thirty-one PWLE participated in four focus groups. Thirty-four outcomes were suggested across the focus groups. Evaluation of the focus groups revealed a high level of satisfaction with the engagement process and some new learning. Seventeen PWLE contributed to the first 2 Delphi rounds and 7 to the third round. The final consensus included 17 PWLE (47%) and 19 DPs (53%). Out of the total of 11 final consensus outcomes considered essential by both PWLE and health professionals, 7 (64%) outcomes mapped across to ones that PWLE initially identified, broadening their definition. One outcome (PWLE effort required for treatment and maintenance) was entirely novel.

CONCLUSIONS

We conclude that engaging PWLE in COS development can be achieved across widely different communities. Furthermore, the process both broadened and enriched overall outcome consensus, yielding important and novel perspectives for health-related research.
