The Impact of Interventional Radiology Educational Webinars during the Coronavirus Disease 2019 Pandemic and Beyond-The Asia Pacific Society of Cardiovascular and Interventional Radiology (APSCVIR) Experience

Purpose: To describe a series of webinars by the Asia Pacific Society of Cardiovascular and Interventional Radiology as a substitute for educational outreach activities during the coronavirus disease 2019 pandemic and beyond. Material and Methods: A retrospective review was performed for 10 webinars organized by Asia Pacific Society of Cardiovascular and Interventional Radiology between July 2021 and February 2024. The target audience was interventional radiology physicians. After each virtual session, the recordings of these sessions were posted online and made accessible via a link on the Asia Pacific Society of Cardiovascular and Interventional Radiology website. Link access to these recorded seminars was also emailed to participants. Descriptive statistics were used for the analysis of the quantitative data. Results: A total of 10 sessions were conducted. There was a median of 258 registered participants, a median attendance of 126, a total attendance of 1,302, and a registration-to-participation conversion percentage of 54%. The majority of attendees (median ≥94%) were Asia Pacific Society of Cardiovascular and Interventional Radiology members. Two-thirds of participants attended for an hour or more (70.7%). The top three videos with the highest viewership and watch time were on arterial treatment to tough hepatocellular carcinoma (633 views, 87.4 hours watched), non-oncological embolization (350 views, 48.9 hours watched), and lower limb angioplasty (334 views, 58.4 hours watched). The two most attended and most viewed webinars were arterial treatment of hepatocellular carcinoma and non-oncological embolization. Conclusions: Use of webinars for interventional radiology education in the Asia Pacific region was well-received and demonstrates the viability of virtual interventional radiology educational programs to reach underserved communities where interventional radiology has room to grow.
