Background Social media amplifies the accessibility, reach and impact of medical education and conferences alike. The use of hashtags at medical conferences allows material to be discussed and improved on by the experts via online conversation on Twitter. We aim to investigate the utilization of hashtags at the American Association for the Surgery of Trauma (AAST) meetings from 2016 to 2019 and its potential role in knowledge dissemination and meeting participations.
Methods Symplur Signals software was used to analyze hashtags for the AAST meetings by year: #AAST2016, #AAST2017, #AAST2018, #AAST2019.
Results Number of tweets decreased significantly from 2016 to 2019 (4500 to 4400 to 3600 to 2600, respectively, p<0.05). Retweets also decreased significantly from 2016 to 2019 (3600 to 3300 to 2600 to 1900, respectively, p<0.05). Users decreased from 2016 to 2019 (1600 to 1400 to 937 to 743, respectively, p<0.05). Despite this decrease, impressions were 5.8 million in 2016, increasing to 8.6 million in 2017, then 9.6 million in 2018 and finally peaking in 2019 where impressions reached 10 million (p<0.05). The top influencer for 2016–2019 was the AAST Twitter account.
Conclusion Twitter #AAST 2016–2019 online engagement and interactions have declined during the last 4 years while impressions have grown steadily indicating potential widespread dissemination of trauma-related knowledge and evidence-based practices, and increased online utilization of conference material to trauma surgeons, residents and fellows, trauma scientists, other physicians and the lay public. #AAST online engagement and impressions did not have influence on meeting attendance rates.

The use of internet platforms has changed the way that modern technology and novel research influences the world of medicine. Online discussion boards are being used to grade medical students, lectures are available on various streaming resources and telehealth is becoming a more popular avenue for improving accessibility to healthcare. With all the advancements in medicine, the field of trauma surgery would benefit from adopting similar practices.
One of the new trends in medical education is holding online journal clubs using forums such as Twitter or WhatsApp. A dermatology program highlighted several of the benefits of using Twitter as a platform for education.1 The wider audience allows for more comprehensive topics to be reviewed as more participants allow for a more thorough exploration of new articles. Participation is not limited by geographic area and there is a public record of topic discussion that can be returned to and viewed at any time. Twitter is useful for subspecialties such as dermatology or trauma surgery by allowing the public to have access to relevant cutting edge information. Conversation on Twitter also facilitates discussions between different specialties allowing for improved comprehension of the topic. The benefits of Twitter can be used for many educational endeavors, including journal clubs, undergraduate medical education and conferences.
Twitter is available to the public, free of charge and simple to operate. By including lay people, medical students and other health professionals in the same forum as subject matter experts, Twitter allows mutual participation in topic discussions. Academic resources can be incredibly costly for students and potentially inaccessible to the public. Accessibility to experts and their breadth of knowledge is an advantage to the public as well as those in medicine who may be unable to attend the conference. Twitter’s format allows physicians to share links to research articles, YouTube videos and websites, along with text on their own intellectual interpretation of the material. The structure of this format is beneficial for facilitating education and communication. For these reasons, Twitter provides a distinct advantage in comparison to other social media platforms.
Research on the use of social media in trauma surgery, specifically in regard to hashtag use at American Association for the Surgery of Trauma (AAST), an international surgical meeting, is limited. We aim to investigate the utilization of hashtags at the AAST meetings from 2016 to 2019 and its potential role in knowledge dissemination and meeting participations.
This is a review of Twitter data collected by Symplur regarding the use of the AAST meeting hashtag from 2016 to 2019. Information was collected for each of the following hashtags: #AAST2016, #AAST2017, #AAST2018 and #AAST2019. To obtain this information we used Symplur Signal software (Upland, CA) which is designed specifically for healthcare-related hashtags. This software allowed us to gather data on tweets, retweets, impressions, influencers, users and titles of research articles tweeted during the conference. Filters were placed on the data sets to allow the most accurate information be obtained from the software, and languages other than English were excluded. Additional filters were placed to ensure that we were only capturing data during the month that the conference took place (September 1 to September 30), meaning data were analyzed yearly and not cumulatively. The AAST Twitter hashtag data were analyzed within the time frame of all of the meetings. Meeting dates were September 14–17, 2016; September 13–17, 2017; September 26–29, 2018; and September 18–21, 2019.2 Using the information from Symplur on the top 10 influencers, data on number of followers and specialty were obtained on analyzing their Twitter profiles. IBM SPSS statistics software V.22 was used for analysis and statistical significance was defined as p<0.05.
Certain definitions were used to explain our data. Engagement is an active form of social media interaction, defined in this study as a tweet or retweet incorporating the meeting hashtag. Impressions are a passive form of interaction, indicating that content containing the meeting hashtag was viewed but no action (such as a comment or retweet) was taken. Influencers are users who had high utilization of the meeting hashtag. Twitter users agreed to participation via general Twitter terms and conditions. This study was reviewed by our Institutional Review Board and the Western Institutional Review Board and was deemed exempt.
Number of tweets decreased significantly from 2016 to 2019, from 4500 to 2800, respectively (p<0.05). Number of retweets also declined significantly from 2016 to 2019, from 3600 to 1900, respectively (p<0.05). Though tweets and retweets declined, impressions increased significantly from 2016 to 2019, from 5.8 million to 10 million (p<0.05), potentially indicating contents from AAST conference presentations were still being widely viewed and disseminated. Twitter users dropped significantly from 2016 to 2019 as well, from 1600 to 743 (p<0.05) (figure 1). The account that used the conference hashtag the most, thus becoming the top influencer, was the AAST organization (@traumadoctors) Twitter account, from 2016 to 2019.
Online engagement measured by tweets and retweets combined decreased significantly from 2016 to 2019, from 8100 to 4700 (p<0.05). Attendance remained relatively constant throughout the years 2016–2019 (figure 1). Figure 2 illustrates international distribution of members of the AAST by country of membership.
Twitter data from the AAST conferences between the years of 2016 and 2019 yielded intriguing results. Tweets, retweets and users decreased over the years while impressions significantly increased, indicating increased reachability and dissemination of conference materials throughout the platform. Engagement did not increase at the same rate that impressions did. Despite the fact that engagement did not increase, conference attendance continued to grow over from 2016 to 2019.
The significant increase in impressions over time is likely due to a combination of the scope of influence of the AAST meeting, the content presented at the meeting and also the increasing use of Twitter by medical professionals. The AAST has over 1300 members in 130 countries and is well established as a leader in the field of trauma surgery. This influence likely plays a role in the increasing number of impressions during AAST conferences. The increasing use of Twitter by medical professionals is also likely to contribute to growing impressions. Twitter is the most popular form of social media used by healthcare professionals due to the ease and freedom of connection, information sharing and communication. The prevalence of healthcare professionals on Twitter is likely the cause for an increase in impressions across several surgical conferences, as seen in figure 3. AAST and Eastern Association for the Surgery of Trauma had consistent upward growth over the years while ASC and ACSCC peaked during 2017. The decreasing engagement at the AAST conference may be related to the concept of social media fatigue. Social media users are constantly bombarded with new content that they must read and respond to, while simultaneously creating their own unique posts. Initially, social media participation was easy to encourage because it was a new and exciting concept, but as its use has become more common, active participation has decreased. An increased amount of social media users are becoming ‘lurkers’ or viewing content without acting on it. This phenomenon could contribute to the decreased amount of engagement.3
The usage of online platforms to improve the diffusion of research, particularly to students, residents and the public, has potential to revolutionize medical education. One orthopedic residency program put this theory to the test by starting a journal club using WhatsApp as the platform for discussion.4 They found that the electronic platform allowed participants to still partake in discourse without the confines of scheduling problems, when given a 4-day window in which to respond. This method increases flexibility, which can contribute to resident satisfaction and willingness to participate. Another study found that up to 23% of a surgical resident’s workday is spent on non-educational endeavors, such as waiting for operating rooms to be ready.5 Using online forums such as WhatsApp or Twitter can help to bridge this downtime during the workday.
Previous studies have analyzed the use of Twitter at conferences, but very little was known about hashtag use at large trauma conferences. The majority of studies found that the use of hashtags increased meeting attendance, tweets and retweets throughout the years within fields such as critical care, cardiology and anesthesiology.6–14 In 2016, the Spanish Association of Surgeons studied the users who had been using their meeting hashtag over the previous four meetings. Their research found that originally, physicians made up 65% of the conference influencers, but by 2016, they only represented 35% of influencers. These data suggest that physician influencers play a vital role in engaging the public to participate in online conversation and education.15
Twitter has the potential to entirely overturn academic communication, particularly during events such as the global COVID-19 pandemic. Many physicians are already using Twitter as an advocacy platform, to exchange the most current information on treatment, and improve education to the public, in addition to encouraging other physicians to join as well. Essential scientific information travels through the ‘Twittersphere’ much faster than it ever could through the rigid structure of online journals and databases. One recent article stated that research would be made public in ‘days rather than months’ but the reality of the current situation is that many of the patients do not have days to spare for their physicians to even obtain treatment information.16
Looking at the international distribution of AAST membership as illustrated in figure 2, nearly every continent is well represented by members, which is both extraordinary and essential for an international trauma organization. Including trauma surgeons and scientists from across the globe in scientific evidence-based online conversations is beneficial to furthering trauma science and advancing patient care. The only continent that was relatively under-represented was Africa. The inclusion and expansion of AAST’s membership and online reach in Africa could be facilitated and enhanced by magnifying efforts from the AAST communication committee and the AAST Twitter handle @traumadoctors. This will potentially result in forming more connections with physicians in Africa via Twitter and could be reflected in AAST meeting attendance and participation in the near future.
To improve the online presence of trauma surgery as a specialty, the AAST could implement a specialized social media team, similar to the Journal of Neurosurgery.17 This team was composed of neurosurgery residents and medical students dedicated to the field, who were assigned to roles as designated editors. These editors created visual abstracts of current research topics, and were subsequently posted on various social media sites. After implementing this team approach to social media accounts (Twitter, Facebook), impressions and online viewing of scientific materials increased significantly. The use of social media creates increased connectivity between specialists and experts. Of note, the new generation of physicians will be proficient in the use of social media and it will likely play a more significant role in dissemination of research over time.
All medical conferences should take advantage of the increased participation that Twitter can provide when properly used. Including links, polls, photos and videos on postings can increase interactions between users. The use of the meeting hashtag should be encouraged as frequently as possible by displaying the hashtag on name tags, meeting handouts and materials, as well as at the beginning and end of presentations. For those who are attending and pursuing Continuing Medical Education Credit, hashtags could be added to those materials as well. Conferences could have a social media station alongside the registration station where participants could directly engage on social media with improved ease of access. Presentations could be set up where questions are asked via a specific Twitter hashtag, allowing a broader audience to participate, including those not in attendance.
Limitations of this study are primarily related to hashtag filters from Symplur software that were used to filter out information irrelevant to conference materials. Since hashtags are publicly available for use, anyone can tweet out information using the conference hashtag, even if it does not pertain to the meeting. Filters were placed to remove tweets that were not published in English or in the North American time zone from data. Twitter engagement relates to the previous year’s attendance. Future studies should investigate the long-term effects of conference hashtag use on knowledge dissemination after the conclusion of the conference. In addition, future research should examine the influence conference material has on Twitter conversations during and after the AAST meeting.
Impressions do not directly indicate information translation. Absorption of information may not occur simply because the content of a tweet was viewed. However, there are indications that increased impressions and engagement may indicate overall scientific advancement. One study of at the conference of the American Urological Association found that the more likes and retweets a presentation received, the more likely it was to be published.18 In addition, tweets can be formatted in a manner that fosters user engagement and thus the likelihood that they would absorb the information. A Twitter blog published in 2014 suggested that by including hashtags, photos and links a tweet was more likely to be interacted with by users.19
Medical conferences should continue to promote use of hashtags at their events in an effort to promote an online presence. The network of scientists created through use of hashtags at conferences is beneficial to patients and students, and can be accessed in almost any circumstance.
Twitter #AAST 2016–2019 online engagement and interactions have declined during the last 4 years while impressions have grown steadily indicating potential widespread dissemination of trauma-related knowledge and evidence-based practices, and increased online utilization of conference material to trauma surgeons, fellows, residents, trauma scientists, other physicians and the lay public. #AAST online engagement and impressions did not have influence on meeting attendance rates. Medical conferences and education alike should take advantage of online platforms, such as Twitter, to facilitate information sharing, stimulate online conversations, and advance trauma science.
