Nationwide Engagement in an Interdisciplinary eLearning Program on Alcohol Dependence in Japan

eLearning has become an essential platform for continuing medical education in Japan, but engagement trends across regions and specialties remain poorly defined. Therefore, this study analyzed participation patterns in an eLearning program jointly organized by the Japanese Society of Alcohol-Related Problems and Addiction Medicine and the Japan Society of Hepatology in an effort to improve clinical skills in alcohol dependence management.

Aggregate data from a nationwide eLearning platform as of June 2025 were analyzed, focusing on prefectural, specialty, and academic society distributions.

In total, 3860 course completions were analyzed. Participation rose continuously from 2022 to 2025. Tokyo had the highest number of participants (n = 511), followed by Osaka (n = 269) and Kanagawa (n = 257). When adjusted for population, Nara Prefecture ranked first in participation (7.70 per 100,000), followed by Wakayama Prefecture (6.94) and Shimane Prefecture (6.24). Psychiatry accounted for 52.0% of participants (mean age, 44.7 years), whereas internal medicine accounted for 39.3% (mean age, 48.7 years). The Japanese Society of Psychiatry and Neurology contributed 44.3% of participants, whereas the Japan Society of Hepatology contributed 20.5%. More than half of the participants worked in hospitals (53.5%). Meanwhile, 60% of the participants completed courses during holidays or outside standard working hours.

This large-scale eLearning initiative achieved nationwide adoption with distinctive regional and specialty disparities. The observed sustained participation in this initiative underscores the value of interdisciplinary collaboration and growing importance of digital education in alcohol-related medicine.
