The Kardashian Index of Cardiologists: Celebrities or Experts?

Physician-scientists or celebrities? Kardashian-index of gastroenterologists

BACKGROUND

The coronavirus disease 2019 pandemic unleashed a flood of untrustworthy information on social media platforms, resulting in the unfortunate consequence of expert scientists' opinions getting lost amidst the chaotic sea of misinformation. The question of how much influence these esteemed scientists hold on social media platforms remains elusive. To address this scientific quandary, we sought to explore the concept of the Kardashian index (K-index), a term introduced by Hall in 2014. This metric provides a rudimentary means of evaluating whether a physician scientist's popularity on social media aligns with their significant scientific contributions.

AIM

To evaluate if a Gastroenterologist physician's popularity on social media is at par with their scientific contributions (research articles and publications).

METHODS

We conducted an extensive search to identify all gastroenterologists actively practicing and associated with the top 100 hospitals as reported by the United States News. We collected specific data on a sub-group including their names, affiliations, degrees, and sub-specializations. To gauge their social media popularity, we utilized the K-index calculation which is determined by dividing the actual number of Twitter followers by the number of researcher's citations. The expected number of followers (F) is calculated using the formula F = 43.3 C ^ 0.32, where C represents the number of citations.

RESULTS

Physicians affiliated with the Mayo Clinic emerged as the most prominent presence on Twitter, constituting 16% of the total. They were followed closely by physicians from Mount Sinai Hospital (9%) and the University of Michigan Hospital (9%). Surprisingly, 76% of the physicians evaluated exhibited a low K-index, falling within the range of 0 to less than 2. This suggests that a significant number of highly influential physician-scientists are not receiving due recognition, as indicated by their relatively low number of followers. On the other hand, 24% of the physicians had an inflated K-index, exceeding 5, which positioned them as the "Kardashians". These individuals enjoyed greater social media popularity than their actual scientific contributions. Interestingly, our analysis revealed no discernible association between sex and K-index (P value of 0.92).

CONCLUSION

In the gastroenterology field, our study estimated that a majority (76%) of highly researched physicians are undervalued despite their significant scientific contributions.

Twitter trends in #Parasitology determined by text mining and topic modelling

This study investigated the emergence and use of Twitter, as of July 2023 being rebranded as X, as the main forum for social media communication in parasitology. A dataset of tweets was constructed using a keyword search of Twitter with the search terms 'malaria', 'Plasmodium', 'Leishmania', 'Trypanosoma', 'Toxoplasma' and 'Schistosoma' for the period from 2011 to 2020. Exploratory data analyses of tweet content were conducted, including language, usernames and hashtags. To identify parasitology topics of discussion, keywords and phrases were extracted using KeyBert and biterm topic modelling. The sentiment of tweets was analysed using VADER. The results show that the number of tweets including the keywords increased from 2011 (for malaria) and 2013 (for the others) to 2020, with the highest number of tweets being recorded in 2020. The maximum number of yearly tweets for Plasmodium, Leishmania, Toxoplasma, Trypanosoma and Schistosoma was recorded in 2020 (2804, 2161, 1570, 680 and 360 tweets, respectively). English was the most commonly used language for tweeting, although the percentage varied across the searches. In tweets mentioning Leishmania, only ∼37% were in English, with Spanish being more common. Across all the searches, Portuguese was another common language found. Popular tweets on Toxoplasma contained keywords relating to mental health including depression, anxiety and schizophrenia. The Trypanosoma tweets referenced drugs (benznidazole, nifurtimox) and vectors (bugs, triatomines, tsetse), while the Schistosoma tweets referenced areas of biology including pathology, eggs and snails. A wide variety of individuals and organisations were shown to be associated with Twitter activity. Many journals in the parasitology arena regularly tweet about publications from their journal, and professional societies promote activity and events that are important to them. These represent examples of trusted sources of information, often by experts in their fields. Social media activity of influencers, however, who have large numbers of followers, might have little or no training in science. The existence of such tweeters does raise cause for concern to parasitology, as one may start to question the quality of information being disseminated.

Guidelines: The Do's, Don'ts and Don't Knows of Creating Open Educational Resources

Background

In medical education, there is a growing global demand for Open Educational Resources (OERs). However, OER creators are challenged by a lack of uniform standards. In this guideline, the authors curated the literature on how to produce OERs for medical education with practical guidance on the Do's, Don'ts and Don't Knows for OER creation in order to improve the impact and quality of OERs in medical education.

Methods

We conducted a rapid literature review by searching OVID MEDLINE, EMBASE, and Cochrane Central database using keywords "open educational resources" and "OER". The search was supplemented by hand searching the identified articles' references. We organized included articles by theme and extracted relevant content. Lastly, we developed recommendations via an iterative process of peer review and discussion: evidence-based best practices were designated Do's and Don'ts while gaps were designated Don't Knows. We used a consensus process to quantify evidentiary strength.

Results

The authors performed full text analysis of 81 eligible studies. A total of 15 Do's, Don't, and Don't Knows guidelines were compiled and presented alongside relevant evidence about OERs.

Discussion

OERs can add value for medical educators and their learners, both as tools for expanding teaching opportunities and for promoting medical education scholarship. This summary should guide OER creators in producing high-quality resources and pursuing future research where best practices are lacking.

Researchers in cardiology – Why and how to get on Twitter?

Social media (SoMe) for professional use has gained importance for scientific impact. In cardiology, Twitter is among the preferred SoMe platforms for scientific dissemination. We are in the middle of a paradigm shift within scientific dissemination as more scientific content is presented on Twitter, and it is crucial to embrace it. Therefore, this paper includes a description and discussion of the existing literature reporting the impact of Twitter on research dissemination, as well as a guide on how to get started. In addition, we describe a case of the Danish Cardiovascular Academy Summer Meeting 2021 as an example of a scientific event that was promoted on Twitter before, during and after the event and present a survey showing that participants were inspired to increase the use of SoMe professionally. Finally, the paper addresses limitations of Twitter and SoMe for scientific use and discuss a need for an increased evidence base.

The Kardashian Index: a study of researchers' opinions on twitter 2014–2021

The Kardashian Index was designed for comedic purposes and meant to highlight researchers with minimal scholar contribution but oversized social media influence. We sought to examine attitudes and understanding of the Kardashian index by conducting a retrospective observational study of tweets retrieved from the Twitter API, Academic Track. From July 30th, 2014 to May 1st, 2021, 5826 unique tweets containing the phrase "Kardashian index” or related search terms were identified. Interest in the Kardashian Index peaked around the time of publication (July 30th, 2014), though the metric received continued discussion. One hundred random tweets were analyzed to see if the conversation points were positive, negative, or neutral. A majority (29%) of the tweets were neutral. Twenty-three percent of the tweets addressed the user’s own K-Index value, while 21% and 17% of the tweets were either critical or joking, respectively. Only a minority of tweets are critical of or appreciate the humor of the Kardashian index. The majority discuss the term matter-of-factly. Although the Kardashian Index was created in a lighthearted manner, a more serious tone emerges, prompting questions about the shifting role of scholarly and public influence.

Frequency of Social Media and Digital Scholarship Keywords in U.S. Medical Schools' Promotion and Tenure Guidelines

PURPOSE

Medical schools must have clear policies and procedures for promotion and tenure (P&T) of faculty. Social media and digital scholarship (SMDS) is an emerging form of scholarship capable of reaching audiences quickly, conveniently, and in a wide variety of formats. It is unclear how frequently SMDS is considered during P&T reviews. The authors sought to determine whether current P&T guidelines at medical schools consider SMDS.

METHOD

The authors acquired P&T guidelines from any U.S. Liaison Committee on Medical Education-accredited medical school (or their governing university) that were available online between October and December 2020. Using an iterative process, they developed a bank of keywords that were specific to SMDS or that could include SMDS between October and December 2020. The authors searched each school's guidelines for each keyword and determined whether the word was being used in relation to crediting faculty for SMDS in the context of P&T procedures. The primary outcome measure was the dichotomous presence or absence of SMDS-specific keywords in each school's P&T guidelines.

RESULTS

The authors acquired P&T guidelines from 145/154 (94%) medical schools. After removing duplicate documents, the authors considered 139 guidelines. The keyword bank included 59 terms, of which 49 were specific to SMDS and 10 were umbrella terms that could be inclusive of SMDS. Of the 139 guidelines, 121 (87%) contained at least 1 SMDS-specific keyword. Schools had a median of 3 SMDS-specific keywords in their P&T guidelines.

CONCLUSIONS

As the presence and impact of SMDS increase, schools should provide guidance on its role in the P&T process. Faculty should receive clear guidance on how to document quality SMDS for their promotion file.

Social Media for the Hepato-Pancreato-Biliary community (#SoMe4HPB): connecting a specialized online group for scientific and clinical knowledge dissemination

BACKGROUND

Social media has an increasingly important role in scientific communication, clinical discussions and knowledge distribution. While several surgical disciplines have taken to internet for increased connectivity, there is currently little knowledge about the social media activity in the field of hepatopancreatobiliary surgery. We aimed to evaluate the implementation and use of a specific HPB hashtag and Twitter handle.

METHODS

The hashtag and Twitter handle (#SoMe4HPB; @hpb_so) were initiated on February 2019. We evaluated the response during the initial 15 months by applying NodeXL to trace activity.

RESULTS

The Twitter handle had 1388 followers (by May 7, 2020) and had generated 855 tweets and retweets. A total of 1120 mentions of 182 accounts were recorded in original tweets by @hpb_so. The largest global reach was recorded in December 2019 (254.000 people). Pancreatic cancer was the subject of 15% of all posts, liver malignancies of 12% of all posts and minimally invasive surgery of 8%.

CONCLUSION

The Social Media for the Hepato-Pancreato-Biliary community (#SoMe4HPB) and its associated Twitter handle @hpb_so had a well-built inception followed by a progressive development connecting individuals interested in HPB Surgery internationally. The involvement of more actors is required in order to fully attain its scientific dissemination role.

Mapping and quantification of the twitter footprint of cardiologists

Aims

The increasing importance placed by medical journals for dissemination of published articles on social media, such as posting Altmetric scores, has further expedited the need for differentiating bona fide science from pseudo-science. The 'Kardashian index' (a.k.a., K-index) was suggested, which correlates the citations of a scientist with his/her Twitter followers.

Methods and results

From a list of top 100 cardiology hospitals in accordance with the most recent US News and World Report rankings, 1500 cardiologists were selected based on institutional physician profile pages complete with cardiologists' headshots. The K-index of cardiologists, and variables like all-time posts, and posts for the past 12 months (1 June 2019 to 31 May 2020) from cardiologists were documented and analysed. The K-index of cardiologists in our study was stratified into the following categories (upper boundary inclusive); K-index 0-1 (n = 104); K-index 1-2 (n = 30); K-index 2-3 (n = 24); K-index 3-4 (n = 14); K-index 4-5 (n = 5); and K-index >5 (n = 22). There was no statistically significant difference (P = 0.94) in the citation number across the K-index categories (no consistent pattern observed, median citations ranging from 237 to 610). However, cardiologists with higher K-index categories had a higher number of 12-month posts (median 14 vs. 392 for K-index categories 0-1 and >5, respectively; P-value <0.001).

Conclusion

Considering no evidence of a difference in the number of citations across K-index categories, the stigma associated with higher K-index needs to be reconsidered.

Social media in surgery: evolving role in research communication and beyond

PURPOSE

To present social media (SoMe) platforms for surgeons, how these are used, with what impact, and their roles for research communication.

METHODS

A narrative review based on a literature search regarding social media use, of studies and findings pertaining to surgical disciplines, and the authors' own experience.

RESULTS

Several social networking platforms for surgeons are presented to the reader. The more frequently used, i.e., Twitter, is presented with details of opportunities, specific fora for communication, presenting tips for effective use, and also some caveats to use. Details of how the surgical community evolved through the use of the hashtag #SoMe4Surgery are presented. The impact on gender diversity in surgery through important hashtags (from #ILookLikeASurgeon to #MedBikini) is discussed. Practical tips on generating tweets and use of visual abstracts are presented, with influence on post-production distribution of journal articles through "tweetorials" and "tweetchats." Findings from seminal studies on SoMe and the impact on traditional metrics (regular citations) and alternative metrics (Altmetrics, including tweets, retweets, news outlet mentions) are presented. Some concerns on misuse and SoMe caveats are discussed.

CONCLUSION

Over the last two decades, social media has had a huge impact on science dissemination, journal article discussions, and presentation of conference news. Immediate and real-time presentation of studies, articles, or presentations has flattened hierarchy for participation, debate, and engagement. Surgeons should learn how to use novel communication technology to advance the field and further professional and public interaction.

Article-Level Metrics

In the era of digitization and Open Access, article-level metrics are increasingly employed to distinguish influential research works and adjust research management strategies. Tagging individual articles with digital object identifiers allows exposing them to numerous channels of scholarly communication and quantifying related activities. The aim of this article was to overview currently available article-level metrics and highlight their advantages and limitations. Article views and downloads, citations, and social media metrics are increasingly employed by publishers to move away from the dominance and inappropriate use of journal metrics. Quantitative article metrics are complementary to one another and often require qualitative expert evaluations. Expert evaluations may help to avoid manipulations with indiscriminate social media activities that artificially boost altmetrics. Values of article metrics should be interpreted in view of confounders such as patterns of citation and social media activities across countries and academic disciplines.

Twitter for professional use in electrophysiology: practical guide for #EPeeps

Social media (SoMe) becomes more and more popular in the cardiological community. Among them, Twitter is an emerging and dynamic medium to connect, communicate and educate academic and clinical cardiologists. However, in contrast to traditional scientific communications, the content provided through SoMe is not peer-reviewed and may not necessarily always represent scientific evidence or may even be used to unjustifiably promote therapies for commercial purposes. For the unintended, this means of communication might be appear difficult to handle. This article aims to provide a practical guide on how to use Twitter efficiently for professional use to keep yourself up-to-date about new techniques, the latest study results and news presented at national or international conferences. Additionally, important limitations will be discussed.

Breakthrough healthcare technologies in the COVID-19 era: a unique opportunity for cardiovascular practitioners and patients

INTRODUCTION

The Coronavirus disease 2019 (COVID-19) pandemic, caused by symptomatic severe acute respiratory syndrome-Coronavirus-2 (SARS-CoV-2) infection, has wreaked havoc globally, challenging the healthcare, economical, technological and social status quo of developing but also developed countries. For instance, the COVID-19 scare has reduced timely hospital admissions for ST-elevation myocardial infarction in Europe and the USA, causing unnecessary deaths and disabilities. While the emergency is still ongoing, enough efforts have been put to study and tackle this condition such that a comprehensive perspective and synthesis on the potential role of breakthrough healthcare technologies is possible. Indeed, current state-of-the-art information technologies can provide a unique opportunity to adapt and adjust to the current healthcare needs associated with COVID-19, either directly or indirectly, and in particular those of cardiovascular patients and practitioners.

EVIDENCE ACQUISITION

We searched several biomedical databases, websites and social media, including PubMed, Medscape, and Twitter, for smartcare approaches suitable for application in the COVID-19 pandemic.

EVIDENCE SYNTHESIS

We retrieved details on several promising avenues for present and future healthcare technologies, capable of substantially reduce the mortality, morbidity, and resource use burden of COVID-19 as well as that of cardiovascular disease. In particular, we have found data supporting the importance of data sharing, model sharing, preprint archiving, social media, medical case sharing, distance learning and continuous medical education, smartphone apps, telemedicine, robotics, big data analysis, machine learning, and deep learning, with the ultimate goal of optimization of individual prevention, diagnosis, tracing, risk-stratification, treatment and rehabilitation.

CONCLUSIONS

We are confident that refinement and command of smartcare technologies will prove extremely beneficial in the short-term, but also dramatically reshape cardiovascular practice and healthcare delivery in the long-term future, for COVID-19 as well as other diseases.

Impact of Randomized Controlled Trials in the Social Media: Does Science Trend As Much As Everyday Events?

BACKGROUND

The approach to the scientific literature is evolving. Currently, dissemination of articles happens in real time through social media (SoMe) channels, and little is known about its impact in medicine. The aim of this study was to investigate if SoMe dissemination followed trends independent from articles type and content.

METHODS

First, the SoMe engagement of a popular theme (#BlackFriday) and a relevant theme (#ClimateChange) was compared using a SoMe analytic tool to test if the popular theme would reach more engagement. In a second analysis, themes in colorectal surgery in the SoMe community were explored. Altmetric Explorer was searched for the term "colorectal surgery" and the outputs were categorized into 'randomized controlled trials' (RCTs) and 'other studies'. Subgroups were compared for the Altmetric scores using statistical analyses.

RESULTS

The analytic tool documented that #BlackFriday outnumbered #ClimateChange in mentions and engagement (1.6 million vs 127.000 mentions). Following, Altmetric Explorer identified 1381 articles, including 92 RCTs (7.1%). Overall, 25,554 mentions were documented from 1205 outputs (97.0% by Twitter). A greater percentage of "other studies" ranked in the lower Altmetric score categories (p = 0.0007). Similarly, the median Altmetric score was higher in the RCT subgroup comparing with "other studies" (6.5 vs. 2.0, Mann-Whitney p = 0.0001).

CONCLUSIONS

In this study, RCTs represented just the 7.1% of the studies and produced 11% of Twitter outputs. The median Altmetric scores obtained by RCTs were higher than those of other studies.

A Short History of Free Open Access Medical Education. The Past, Present, and Future

Free Open Access Medical education (FOAM) has taken the emergency medicine and critical care worlds by storm in the past decade. This article represents one perspective on the stages of transition for FOAM from its humble beginnings as a grassroots movement to the more recent multiauthor blogs that are described in the peer-reviewed literature. In this article, the authors describe the following four distinct waves of people within the movement, with each wave creating a new stage in the evolution of the FOAM community: Creation by the Founders, Adoption by the Enthusiasts, Structure and Formalization by the Structuralists, and Engagement and Activity by the End Users. The authors contextualize some of the phenomena that have been observed within this field and highlight challenges for the field moving forward.
