Interactive Health (IH) research increasingly engages patients through participatory and user-centred approaches. However, patients' lived experiences are typically treated more as data to be analysed than as knowledge in their own right. In this paper, I argue that 'patient voice' in the field of IH is both an inclusion issue and an epistemic one. More specifically, it concerns how experiential accounts are recognised and circulated. I examine how methodological conventions, authorship norms, review criteria, and publication formats tend to position patients as participants rather than as authors of evidence. Looking to patient-partnered practices in medical publishing, including The BMJ, JAMA, and British Journal of Sports Medicine, I outline a possible infrastructural pathway for supporting patient-authored or patient-led experiential contributions within the field. I present this as a design probe to surface assumptions and trade-offs. I end this paper by inviting the IH community to reflect on how its knowledge infrastructures might accommodate experiential evidence alongside established research forms.
