Rates of Registry Research Have Increased in Podium and Poster Presentations at the American Association of Hip and Knee Surgeons.

Background: As state, regional, and national registries have rapidly expanded, the goal of this study is to assess the frequency of registry abstracts accepted for both podium and poster presentations at the American Association of Hip and Knee Surgeons between 2012 and 2022.

Methods: Final programs and poster e-collections were examined over the past 11 years. Two reviewers evaluated each abstract to determine if they utilized large datasets and the location of each registry. Studies were excluded if they used institutional registries. Reviewers also identified the most frequently utilized registries to determine how their use has fluctuated over this time frame.

Results: A total of 3354 abstracts were reviewed and included. Of those, 577 abstracts utilized data obtained from orthopaedic registries (17.2%): 450 of which were poster presentations (16.5% of total poster acceptances), and 127 were podium presentations (20.5% of accepted podiums). The National Surgical Quality Improvement Program (NSQIP) was the most frequent dataset utilized, with 118 (20.5%) abstracts. Of note, NSQIP's use peaked between 2018 and 2020 and has since slowly trended downward. On the other hand, use of both American Joint Replacement Registry (AJRR) and PearlDiver registry have drastically increased since 2019, with only 6 abstracts chosen in 2019 and 28 abstracts in 2022 (10 AJRR [3 podiums] and 18 PearlDiver [6 podiums]). The proportion of registry data has increased, with the registry abstracts peaking in 2022 as 24% of posters and 37% of podium utilized data from large registry data sets ( < .001).

Conclusions: There has been a significant increase in the number of studies utilizing registry data for both podium and poster presentations at the American Association of Hip and Knee Surgeons annual meeting. While NSQIP was the most utilized, its use has steadily declined while AJRR and PearlDiver use have increased over the past 3 years. Individuals should understand the strengths and weaknesses of each registry before making conclusions on study results.

Level Of Evidence: Level IV.
