Impact of presentation at conference with timed release of academic publication

Fast-tracking publication of original research to coincide with a conference presentation ("coordinated publication") is a mechanism of rapidly disseminating new data. How often this occurs, whether its frequency is changing, and the impact of this approach on information dissemination, is unknown. Our objective was to describe the characteristics of coordinated publications, how the practice has changed over time, and evaluate its potential impact on dissemination of study results. We conducted a cross-sectional study of randomized controlled trials published in NEJM, Lancet, and JAMA between January 1, 2015, and December 31, 2019. Among the 1533 included randomized controlled trials, 502 (33%) had coordinated publications. Coordinated publications increased from 30% [n = 94] in 2015 to 37% [n = 136] in 2019. Coordinated publications were more likely to be unblinded (61% [n = 305] vs. 52% [n = 532]) and more likely to be funded by industry (50% [n = 249] vs. 30% [n = 311]). The strongest predictor of a coordinated publication was cardiovascular disease subspecialty (OR = 3.96, 95% CI [2.95, 5.36]). The median number of citations (188 vs. 98) and the median Altmetric score (318 vs. 182) were higher for coordinated publications than non-coordinated publications. These differences persisted in a multivariable regression model. Coordinated publication is increasingly common. While coordinated publications may generate greater attention, they were observed to be more likely to be unblinded and more likely to be funded by industry, raising questions about the value and intentions of such promotion.
