Analysis of Publication Trends for the 2011-2015 American Orthopaedic Society for Sports Medicine Annual Meeting Abstracts.

Background: Academic conferences are sources of novel research that can influence clinical decision making. Orthopaedic surgery maintains a relatively high rate of publication compared with other surgical subspecialties, and sports medicine conferences hold an even higher rate within the subspecialty. The American Orthopaedic Society for Sports Medicine (AOSSM) annual meetings have been shown to have among the highest rates of publication for accepted abstracts.

Purpose: To determine differences between 2-year publication rates of poster and podium abstracts accepted into the AOSSM annual meetings and identify factors associated with publication.

Study Design: Cross-sectional study.

Methods: The AOSSM archives were queried for all accepted poster and podium presentations for annual meetings from 2011 through 2015. Google Scholar and MEDLINE databases were used to determine which abstracts transitioned into journal articles. Publication rates were compared based on publication 2 years following presentation. Logistic regression was performed to demonstrate which variables were most correlated with successful publication. Data on publication impact factor and number of citations were collected by use of the InCites database.

Results: Of 628 abstracts accepted during this period, 265 were poster presentations and 363 were podium presentations. Overall, 44.7% of abstracts presented were accepted into peer-reviewed journals within 2 years of presentation. No statistical difference was found between poster and podium presentations for journal publication ( P = .328). Poster presentations were published in journals with statistically lower impact factor ( P = .005) and had a statistically lower number of citations ( P < .001) compared with podium presentations. Multivariate logistic regression analysis demonstrated that only number of authors was correlated with publication ( P = .003).

Conclusion: Podium and poster presentations accepted into AOSSM conferences had equal rates of publication within 2 years and should influence decision making equally. The relative impact of podium presentations appeared to be greater, which suggests that the AOSSM selects podium presentations that will have greater clinical impact. Increasing number of coauthors was the only factor found to be correlated with publication.
