Conflicts of interest in submissions and testimonies to an Australian parliamentary inquiry on menopause.

Conflicts of interest (COIs) have the potential to create bias in research, policy and practice. Although disclosure cannot fully protect individuals and public policy from vested interests, it is an important step to support trust in scientific and public discourse, and transparency in decision-making. However, COIs are often unreported, underreported or difficult to identify. This study aimed to assess the extent to which COIs are voluntarily declared by those who make submissions to government inquiries relating to health, focusing on the 2024 Australian Senate inquiry into perimenopause and menopause. There was no guidance or formal requirement to provide COI declarations in written submissions to the inquiry. However, a statement about COI declarations was given by the Chair of the inquiry at the start of public hearings in which verbal testimony was given. All 284 written submissions and 163 verbal testimonies were reviewed to identify the number and nature of COIs declared. Only 1% of written submissions and 6% of verbal testimonies provided a COI statement. The amount and nature of information provided in COI declarations varied widely. To ensure transparency in decisions made as a result of public inquiries, governments should require that COIs be declared for all submissions. An explicit standardized guide is needed, with clear parameters about the type of detail needed for these declarations. Processes for dealing with COIs should also be clear in any reports or recommendations that are made from the evidence presented at such inquiries.
