Introduction Genomic settings are complex and challenging for informed decision making. Partnering with patients and professionals, we aimed to coproduce an innovative intervention for cancer patients to improve decision making and COnsent in GENomic Testing (CoGenT).

Methods Developing the CoGenT intervention, incorporating an online Dynamic Consent Platform (DCP) and Question Prompt List (QPL), involved: i) interviews with 34 stakeholders (cancer patients who were/were not taking part in genomic research, carers, study coordinators, clinicians) to elicit information needs (for QPL) and ‘think-aloud’ feedback on an existing non-cancer DCP; ii) drafting the first QPL about genomic research participation and iii) interviews with 22 stakeholders for feedback, resulting in a prototype DCP to support cancer patients offered genomic testing.

Results Information needs revolved around genomic testing, results/implications, and research participation. Interviews suggested we could enhance QPL utility by providing answers. Views on the DCP highlighted its potential value to inform patients, enable them to indicate preferences, and identify where they need support. Interviews demonstrated the importance of optimizing clarity, accessibility, and engagement in the CoGenT DCP. The QPL includes 29 questions and brief answers on which consent personnel can elaborate if desired. Feedback was positive about the QPL. We refined wording to address participants’ suggestions. The prototype DCP is being iteratively reviewed and revised through further stakeholder interviews.

Discussion The CoGenT intervention is valued by patients, clinicians, and research personnel. This work will facilitate equitable access to cancer genomic research by ensuring consent processes meet the needs of key stakeholders.

Conclusion We will pilot the CoGenT intervention to assess effects on decision-quality outcomes compared with usual consent processes in cancer genomic studies. If results are positive, these evidence-based resources will help establish practices to follow when genomic testing enters routine care, with patients and families well-prepared and supported before, during and after testing.
