Unsolicited Invitations to Scientific Meetings: Radiologists' Experience.

Abstract

Unsolicited invitations to speak at medical meetings have proliferated as a type of spam email and phishing strategy to scam unsuspecting victims. We sought to determine the prevalence of such invitations to questionable meetings and determine the factors associated with receiving such solicitations. Data was collected for the number of speakers' invitations received over a 2-week period (April -May 2023) by radiologists of different subspecialties, academic ranks, and histories of publications and speaking engagements in the past 2-5 years. We analyzed the number of invitations received based on the variables. Thirty-three of 45 (73.3%) faculty members received 188 inappropriate invitation emails in the 2-week observation period. The mean number of invitation emails was 4.13 for each faculty (SD: 5.03, range 0-20). There was no correlation between the number of invitations and radiologists' subspecialty, academic rank (3.8 ± 5, 3.0 ± 4, and 5.5 ± 5.7 invitations for full, associate, and assistant professors respectively) and previous legitimate speaker invites. Only 6 (3.2%) out of 188 invitations to speak sent to radiologists were for radiology-related meetings. Having more than 10 publications since 2022 was associated with a 5.0 (1.2, 19.4) times higher odds of receiving more than 4 solicitations. A total of 73.3% of the faculty surveyed received unsolicited invitations to meetings in the 2-week study period and over 96% of the invitations were unrelated to their field of practice. Our results show that publications since 2022 was the most significant factor associated with receiving more solicitations. Invitations to questionable meetings targeting radiologists are frequent and often are unrelated to their specialties. The risk factors for receiving the invitations are unclear. Understanding these risk factors may enable educators especially junior investigators, to be better prepared to appropriately address such solicitations.
