“Publish or perish”—presentations at annual national orthopaedic meetings and their correlation with subsequent publication

BACKGROUND: Presentation of research at annual national orthopaedic conferences not only serves as a forum for the dissemination of knowledge but is also often a requirement of orthopaedic training programmes. The expected outcome is publication in a peer-reviewed journal. However, publication rates vary for a variety of reasons. The objective of this study was to determine publication rates of presentations from our local Singapore Orthopaedic Association (SOA) annual scientific meeting (ASM) and some of the potential associated factors. We also compared our findings to equivalent meetings worldwide to assess value of scientific content of various orthopaedic conferences. METHODS: All presentations of six SOA ASMs were entered into a database. Using presentation titles, author names and keywords in PubMed and Google Scholar, we determined how many presentations progressed to publication in a peer-reviewed journal. Various comparisons were made to determine factors that could influence publication rates. A comparison with national orthopaedic meetings of America, United Kingdom, Ireland, Australia, Germany, Turkey and Brazil was also conducted. RESULTS: Excluding the ASMs with less than 4 years of follow-up, the publication rate was 35.8%. Both podium and international presenters were found to have significantly higher publication rates than poster and local presenters, respectively, while basic science and clinical research were found to have equivalent rates. Publication rates from other countries’ national conferences ranged between 26.6% and 58.1%. CONCLUSIONS: We suggest that the quality of a presentation is related to its subsequent publication in a peer-reviewed journal. Our findings support the general consensus that the annual meeting of the American Academy of Orthopaedic Surgeons (AAOS) is the gold standard for the dissemination of orthopaedic knowledge updates and advancements in our specialty. Each national orthopaedic association could determine the ratio of “presentations at ASM” to “publication within five years of presentation” and use this as a measure of their annual conference’s impact on the addition and advancement to the orthopaedic literature. This tool may in turn assist clinicians in determining which meetings to attend

Processing time not modality dominates shift costs in the modality-shifting effect

Shifting attention between visual and auditory targets is associated with reaction time costs, known as the modality-shifting effect. The type of modality shifted from e.g., auditory or visual is suggested to have an effect on the degree of cost. Studies report greater costs shifting from visual stimuli, yet notably used visual stimuli that are also identified slower than the auditory. It is not clear whether the cost is specific to modality effects, or with identification speed independent of modality. Here, in order to interpret whether the effects are due to modality or identification time, switch costs are instead compared with auditory stimuli that are identified slower than the visual (inverse of tested previously). A second condition used the same auditory stimuli at a low intensity, allowing comparison of semantically identical stimuli that are even slower to process. The current findings contradicted suggestions of a general difficulty in shifting from visual stimuli (as previously reported), and instead suggest that cost is reduced when targets are preceded by a more rapidly processed stimulus. ‘Modality-Shifting’ as it is often termed induces shifting costs, but the costs are not because of a change of modality per se, but because of a change in identification speed, where the degree of cost is dependent on the processing time of the surrounding stimuli
