In 2015 and 2016, the Canadian Journal of Emergency Medicine (CJEM) Social Media (SoMe) Team collaborated with established medical websites to promote CJEM articles using podcasts and infographics while tracking dissemination and readership.
CJEM publications in the "Original Research" and "State of the Art" sections were selected by the SoMe Team for podcast and infographic promotion based on their perceived interest to emergency physicians. A control group was composed retrospectively of articles from the 2015 and 2016 issues with the highest Altmetric score that received standard Facebook and Twitter promotions. Studies on SoMe topics were excluded. Dissemination was quantified by January 1, 2017 Altmetric scores. Readership was measured by abstract and full-text views over a 3-month period. The number needed to view (NNV) was calculated by dividing abstract views by full-text views.
Twenty-nine of 88 articles that met inclusion were included in the podcast (6), infographic (11), and control (12) groups. Descriptive statistics (mean, 95% confidence interval) were calculated for podcast (Altmetric: 61, 42-80; Abstract: 1795, 1135-2455; Full-text: 431, 0-1031), infographic (Altmetric: 31.5, 19-43; Abstract: 590, 361-819; Full-text: 65, 33-98), and control (Altmetric: 12, 8-15; Abstract: 257, 159-354; Full-Text: 73, 38-109) articles. The NNV was 4.2 for podcast, 9.0 for infographic, and 3.5 for control articles. Discussion Limitations included selection bias, the influence of SoMe promotion on the Altmetric scores, and a lack of generalizability to other journals.
Collaboration with established SoMe websites using podcasts and infographics was associated with increased Altmetric scores and abstract views but not full-text article views.
2015年和2016年，《加拿大急诊医学杂志》（CJEM）社交媒体团队与成熟的医学网站合作，利用播客和信息图表推广CJEM的文章，同时跟踪传播情况和读者数量。
CJEM社交媒体团队根据急诊医生的兴趣程度，选择“原创研究”和“最新技术”板块中的出版物进行播客和信息图表推广。回顾性地选取2015年和2016年Altmetric得分最高且接受过标准脸书和推特推广的文章组成对照组，排除关于社交媒体主题的研究。传播情况通过2017年1月1日的Altmetric得分进行量化，读者数量通过三个月内摘要和全文的浏览量来衡量。通过将摘要浏览量除以全文浏览量来计算需要浏览的次数（NNV）。
符合纳入标准的88篇文章中，29篇被纳入播客组（6篇）、信息图表组（11篇）和对照组（12篇）。计算了播客组（Altmetric：61，42 - 80；摘要：1795，1135 - 2455；全文：431，0 - 1031）、信息图表组（Altmetric：31.5，19 - 43；摘要：590，361 - 819；全文：65，33 - 98）和对照组（Altmetric：12，8 - 15；摘要：257，159 - 354；全文：73，38 - 109）文章的描述性统计数据（均值，95%置信区间）。播客组文章的NNV为4.2，信息图表组为9.0，对照组为3.5。讨论局限性包括选择偏倚、社交媒体推广对Altmetric得分的影响以及缺乏对其他期刊的普遍性。
与成熟的社交媒体网站合作使用播客和信息图表与Altmetric得分及摘要浏览量的增加相关，但与全文文章浏览量无关。
