Criteria for Summit Surplus Sharing*

Pertains to Member Organizations that hold an annual meeting or a meeting that coincides with a THSNA Summit year.

  • Holds a national meeting in the same year as THSNA Summit with invitation and/or submitted abstract-based presentations, which cover broad topics with a goal of advancing scientific and clinical knowledge within the scope of the organization and will defer such a meeting on a THSNA Summit year (to avoid splitting of health care professional participation to both meetings)**.


  • Holds a national meeting in the same year as the THSNA Summit and is not expected to appreciably draw attendees from the THSNA Summit (i.e., expected attendance of health care professionals <150, or by its content, the meeting is not expected to compete with the THSNA Summit).


  • Holds a meeting that is not national and is not expected to appreciably draw attendees from the THSNA Summit.

*Member organization may participate in the THSNA Summit Meeting even if they are not eligible for the share plan.
**If a member organization plans to hold a national meeting that would potentially draw attendees away from the THSNA Summit (i.e., >150 health care professional attendees), this can be allowed with the proviso that this organization is acknowledged/participates in the Summit but does not qualify to receive funds from the Summit share plan.
