The Representation of Women Moderators at The Society of Thoracic Surgeons Annual Meeting.

Background: Recently, there has been an increase in the representation of women within the cardiothoracic surgery workforce, with discussions about gender equity garnering interest. We sought to identify whether this increase is accompanied by commensurate selection for representation at national meetings.

Methods: Online archives of The Society of Thoracic Surgeons (STS) Annual Meetings were reviewed from 2015 to 2024. Data regarding the moderator's gender were abstracted. The gender distribution of moderators across the various session categories was surveyed, and subgroup analyses were performed.

Results: During the years of study, the STS Annual Meeting Taskforce selected 983 moderators to participate in the conference, including 218 women. The representation of women moderators demonstrated a favorable, upward trend. In 2015, 12.1% of moderators were women, with a consistent rate from 2015 to 2018. There was a noticeable rise in invited women moderators in 2019, with 25.4% of moderators being women. This proportion increased to 36.9% women in 2024. General Thoracic sessions have consistently included a greater percentage of women moderators compared with other sessions. Other topic areas, such as Education and Quality Improvement and Critical Care, transitioned to greater representation of women in recent years.

Conclusions: There has been an increase over time in women moderators selected for participation in the STS Annual Meeting, with progress in gender diversity seen in most session types. Although the overall proportion of women within cardiothoracic surgery remains low, the STS has increasingly worked toward encouraging inclusivity. Efforts to further support well-rounded representation are of important benefit.
