Study Groups and POSNA: A Review of Podium Presentations From 2006 to 2020.

Abstract

Study groups are multicenter collaborations aimed at improving orthopaedic decision-making through higher-powered, more generalizable studies. New research is disseminated through peer-reviewed literature and academic meetings, including the Pediatric Orthopaedic Society of North America (POSNA) annual meeting, which brings together academic and medical professionals in pediatric orthopaedics. The goal of this study was to identify patterns in podium presentations (PP) at the POSNA annual meeting resulting from multicenter study groups during a 15-year period. A total of 2065 PP from the 2006 to 2020 POSNA annual meetings were identified. The abstracts of each PP were reviewed to determine if they resulted from a multicenter study group and for characteristics including subspecialty focus. PP from 2006 to 2018 were further reviewed for publication in academic journals. Pearson correlation was used to assess change in the number of PP resulting from study groups overtime. Univariate analysis was used to compare characteristics of PP based on study group involvement (significance P<0.05). The proportion of PP resulting from study groups increased from 2.2% (n=2) in 2006 to 9.4% in 2020 (n=16) (R2=0.519, P=0.002). Of the PP resulting from study groups, 52.9% focused on spine, 26.5% on hip, 2.9% on sports, and 2.0% on trauma. This is compared with a distribution of 16.7% (P<0.001) spine, 15.9% (P=0.005) hip, 9.5% (P=0.026) sports, and 14.6% (P<0.001) trauma focus of PP not from study groups. There was no difference in publication rate of PP resulting from study groups compared with those that were not (69.1% vs. 66.2%, P=0.621). In the 15-year period from 2006 to 2020, there was a nearly 5-fold increase in the proportion of POSNA PP resulting from study groups. Spine surgery is disproportionately supported by study groups, suggesting that there is an opportunity to establish new study groups across the breadth of pediatric orthopaedics. Level V.
