RESUMEN
BACKGROUND: To better understand the research impact on social media, alternative web-based metrics (Altmetrics) were developed. Open access (OA) publishing, which allows for widespread distribution of scientific content, has become increasingly common in the medical literature. However, the relationship between OA publishing and social media impact remains unclear. PURPOSE: To compare social media attention and citation rates between OA and subscription access (SA) research articles within the orthopaedic and sports medicine literature. STUDY DESIGN: Cross-sectional study. METHODS: Articles published as either OA or SA in 5 high-impact hybrid orthopaedic journals between January 2019 and December 2019 were analyzed. The primary outcome was the Altmetric Attention Score (AAS), a validated measure of social media attention. Secondary outcomes included citation rates, article characteristics, and the number of shares on social media. Independent t tests and chi-square analyses were used to compare outcomes between OA and SA articles. A multivariable linear regression analysis was performed to determine the association between article type and AAS while controlling for bibliometric characteristics. RESULTS: A total of 2143 articles (246 OA articles, 11.5%; 1897 SA articles, 88.5%) were included. The mean AAS among all OA articles was 62.4 ± 184.6 (range, 0-2032), whereas the mean AAS among all SA articles was 18.4 ± 109.8 (range, 0-3425), representing a statistically significant difference (P < .001). The mean citation rate among OA articles was significantly higher (17.0 ± 22.5; range, 0-139) than that of SA articles (8.6 ± 13.4; range, 0-169) (P < .001). Multivariable linear regression analysis demonstrated that OA status (ß = 15.15; P = .044), number of institutions (ß = 2.13; P = .023), studies classified as epidemiological investigations (ß = 107.40; P < .001), and disclosure of a conflict of interest (ß = -11.18; P = .032) were significantly associated with a higher AAS. CONCLUSION: OA articles resulted in significantly greater AAS and citations in comparison with SA articles. Articles published through the OA option in hybrid journals as well as those with a higher number of institutions, those that disclosed a conflict of interest, and those classified as epidemiological investigations were positively associated with greater AAS in addition to a greater number of citations. The potential for more extensive research dissemination inherent in the OA option may therefore translate into greater reach and social media attention.

Purpose: To compare social media attention and citation rates between technique articles and matched original research articles (ORAs) regarding surgical procedures. Methods: All technique articles published from August 2019 through July 2020 in the free, electronic versions of Arthroscopy Techniques and JBJS Essential Surgical Techniques were matched by topic to articles in the "Original Research" sections of Arthroscopy, Sports Medicine, and Rehabilitation and JBJS Open Access in a 4:1 ratio within this time frame. The primary outcome was the Altmetric Attention Score (AAS). Secondary outcomes included citations, bibliometrics, and social media metrics. Independent t tests were used to compare primary and secondary outcomes between technique articles and ORAs. A multivariate linear regression analysis was performed to determine the association between article type and social media attention while controlling for confounding bibliometric characteristics. Results: A total of 285 matched research articles (n = 57, 20.0%) and technique articles (n = 228, 80.0%) were included. The mean AAS among all technique articles was 3.63 ± 10.08 (range, 0-96) whereas the mean AAS among all ORAs was 1.30 ± 3.98 (range, 0-25), representing a statistically significant difference (P = .016). The mean citation rate among all technique articles was not significantly different from that among ORAs (P = .73). Multivariate linear regression analysis showed a statistically significant positive association between AAS and article type, with an additional mean increase in the AAS of 2.91 (95% confidence interval, 0.04-5.77; P = .047) for every technique article compared with an ORA. Furthermore, a significant positive relation was noted between the article origin and the AAS, with an increase in the AAS of 3.00 (95% confidence interval, 0.82-5.17; P = .007) for every article published in North America compared with an article originating from another continent. Conclusions: Technique articles resulted in significantly greater AASs and social media attention in comparison with open-access ORAs on similar topics. Publications that described technical procedures in a technique journal and studies from North America were positively associated with greater AASs and greater numbers of citations received by articles. Clinical Relevance: An improved understanding of how much attention is given to technique articles versus matched ORAs by social media may influence the methods authors and journals use for distributing content. The present study suggests that one option to increase the amount of social media attention received for a particular study may be to utilize an accompanying surgical technique video or illustrations as these are easily shareable on social media and offer rapid dissemination of knowledge, similar to that of an infographic. However, physicians who view multimedia within technique articles should be encouraged to review the accompanying articles and the supporting original research as a primary source before making changes in their clinical practice.
