For radiation oncology, social media is a favored communication platform, but it uses non-structured hashtags, which limits communication. In this work, we created a set of structured hashtags with key opinion leaders in radiation oncology, and we report on their use after two years post-deployment.

Hashtags were created, voted on, and refined by crowdsourcing 38 international experts, including physicians, physicists, patients, and organizations from North America, Europe, and Australia. The finalized hashtag set was shared with the radiation oncology community in September 2019. The number of tweets for each hashtag was quantified via Symplur through December 2021. For the top five tweeted hashtags, we captured the number of yearly tweets in the pre-deployment and post-deployment periods from 09/01/2019 to 08/31/2021.

The initial 2019 list contained 39 hashtags organized into nine categories. The top five hashtags by total number of tweets were: #Radonc, #PallOnc, #MedPhys, #SurvOnc, and #SuppOnc. Six hashtags had less than 10 total tweets and were eliminated. Post-deployment, there was an increase in the yearly tweets, with the following number of tweets by the second year post-deployment: #RadOnc (98,189 tweets), #MedPhys (15,858 tweets), and #SurvOnc (6,361 tweets). Two popular radiation oncology-related hashtags were added because of increased use: #DEIinRO (1,603 tweets by year 2) and #WomenWhoCurie (7,212 tweets by year 2). Over the two years, hashtags were used mostly by physicians (131,625 tweets, 34.8%).

We created and tracked structured social media hashtags in radiation oncology. These hashtags disseminate information among a diverse oncologic community. To maintain relevance, regular updates are needed.

We aimed to evaluate recent Instagram and Twitter posts to identify the primary disseminators of information related to radiation therapy on social media (health care professionals vs patients), to characterize their influencer status, and to characterize the content of this information.

Using 2 commercial hashtag analytics platforms, 1000 of the most recent eligible posts from each platform were evaluated for content, tone, and engagement, as well as user (poster) characteristics. Inclusion criteria were as follows: unique posts, written in English, relevant to human cancer treatment, and containing 1 of 11 predetermined hashtags (#radiation, #radiotherapy, #radiationtherapy, #radiationoncology, #radonc, #radiationtherapist #radiationtreatment, #medphys, #cyberknife, #radiosurgery, #protontherapy).

Users of radiation oncology content on Instagram were primarily patients/caregivers (47%), specifically adult patients (94%) with breast cancer (53%). Patient/caregiver content was focused on patient experience (79%), with approximately half specific to radiation therapy (51%), and most patient/caregiver posts demonstrated a positive tone (86%). In contrast, Twitter content was dominated by health care professionals (53%), specifically within radiation oncology (90% of unique users). Health care professional content was focused on colleague education/research dissemination (53%), with a high proportion of posts specific to radiation therapy (95%).

Given the disproportionate number of patients versus radiation oncology professionals active on Instagram versus Twitter, and the lack of radiation therapy-specific content on Instagram, there may be an opportunity to improve patient outreach and education by promoting the presence of radiation oncologists on Instagram.

Due to coronavirus disease 2019 pandemic caused by severe acute respiratory syndrome coronavirus 2, there has been a major reallocation of resources that has impacted the treatment of many diseases, including cancer. The growing use of information and communication technologies (ICT), together with a new approach to work aimed at ensuring the safety of health care professionals and patients alike, has allowed us to maintain the quality of care while ensuring biosecurity. The application of ICT to health care (eHealth) aims to significantly improve the quality, access to, and effectiveness of medical care. In fact, the expanded use of ICT has been recognized as a key, cost-effective priority for health care by the World Health Organisation. The medical speciality of radiation oncology is closely linked to technology and as a consequence of coronavirus disease 2019, ICT has been widely employed by radiation oncologists worldwide, providing new opportunities for interaction among professionals, including telemedicine and e-learning, while also minimizing treatment interruptions. Future research should concentrate on this emerging paradigm, which offers new opportunities, including faster and more diverse exchange of scientific knowledge, organizational improvements, and more efficient workflows. Moreover, these efficiencies will allow professionals to dedicate more time to patient care, with a better work-life balance. In the present editorial, we discuss the opportunities provided by these digital tools, as well as barriers to their implementation, and a vision of the future.
