Appreciation of literature by the anaesthetist: A comparison of citations, downloads and Altmetric Attention Score.

ABSTRACT: BACKGROUND:Different metrics exist to evaluate the impact of a paper. Traditionally, scientific citations are leading, but nowadays new, internet-based, metrics like downloads or Altmetric Attention Score receive increasing attention. We hypothesised a gap between these metrics, reflected by a divergence between scientific and clinical appreciation of anaesthesia literature. METHODS:We collected the top 100 most cited and the top 100 most downloaded articles in Acta Anaesthesiologica Scandinavica (AAS) and Anesthesia & Analgesia (A&A) published between 2014 and 2018. We analysed the relationship between the average number of citations per year, downloads per year and Altmetric Attention Score. RESULTS:For both AAS and A&A, a significant correlation between the 100 most cited articles and their downloads (r = .573 and .603, respectively, P < .001) was found. However, only a poor correlation with Altmetric Attention Score was determined. For the 100 most downloaded articles, download frequency did not correlate with their number of citations (r = .035 and .139 respectively), but did correlate significantly with the Altmetric Attention Score (r = .458 and .354, P < .001). CONCLUSION:Highly cited articles are downloaded more frequently. The most downloaded articles, however, did not receive more citations. In contrast to the most cited articles, more frequently downloaded papers had a higher Altmetric Attention Score. Thus, a 'trending' anaesthesia paper is not a prerequisite for scientific appreciation, reflecting a gap between clinical and scientific appreciation of literature.

Project description:Background: Given the increasing interest and potential use of social media for the promotion of orthopedic literature, there is a need to better understand Altmetrics. Purposes: We sought to determine the relationship between the Altmetric Attention Score (AAS) and the number of citations for articles on total joint arthroplasty (TJA) published in orthopedics journals. We also sought to determine the predictors of greater social media attention for these articles. Methods: Articles on TJA published in Bone and Joint Journal (BJJ), Journal of Bone and Joint Surgery (JBJS), Clinical Orthopedics and Related Research (CORR), Journal of Arthroplasty, Journal of Knee Surgery, Hip International, and Acta Orthopaedica in 2016 were extracted (n = 498). One-way analysis of variance with Bonferroni corrections was used to compare AAS and citations across journals. Multivariate regressions were used to determine predictors of social media attention and number of citations. Results: The mean AAS and number of citations were 7.5 (range: 0-289) and 16.7 (range: 0-156), respectively. Significant between-group effects were observed according to journal for AAS and number of citations. Publishing an article in JBJS was the strongest predictor of higher number of citations. Publishing an article in BJJ was the only independent predictor of higher AAS, while publishing an article in JBJS or CORR trended toward statistical significance. A higher AAS was a significant predictor of a higher number of citations. Number of citations and number of study references were positive predictors of greater social media attention on Twitter and Facebook. Conclusions: In articles on TJA published in 7 journals in 2016, a higher AAS was a associated with a higher number of citations. Various bibliometric characteristics were found to be significantly associated with greater social media attention; the most common influences were number of citations and number of references. Researchers in orthopedics can use this information when considering how to assess the impact of their work.

Project description:The number of retracted articles has grown fast. However, the extent to which researchers and the public are made adequately aware of these retractions and how the media and social media respond to them remains unknown. Here, we aimed to evaluate the media and social media attention received by retracted articles and assess also the attention they receive post-retraction versus pre-retraction. We downloaded all records of retracted literature maintained by the Retraction Watch Database and originally published between January 1, 2010 to December 31, 2015. For all 3,008 retracted articles with a separate DOI for the original and its retraction, we downloaded the respective Altmetric Attention Score (AAS) (from Altmetric) and citation count (from Crossref), for the original article and its retraction notice on June 6, 2018. We also compared the AAS of a random sample of 572 retracted full journal articles available on PubMed to that of unretracted full articles matched from the same issue and journal. 1,687 (56.1%) of retracted research articles received some amount of Altmetric attention, and 165 (5.5%) were even considered popular (AAS>20). 31 (1.0%) of 2,953 with a record on Crossref received >100 citations by June 6, 2018. Popular articles received substantially more attention than their retraction, even after adjusting for attention received post-retraction (Median difference, 29; 95% CI, 17-61). Unreliable results were the most frequent reason for retraction of popular articles (32; 19%), while fake peer review was the most common reason (421; 15%) for the retraction of other articles. In comparison to matched articles, retracted articles tended to receive more Altmetric attention (23/31 matched groups; P-value, 0.01), even after adjusting for attention received post-retraction. Our findings reveal that retracted articles may receive high attention from media and social media and that for popular articles, pre-retraction attention far outweighs post-retraction attention.
