Preliminary study: Descriptive analysis of longitudinal data on the international session of the Japan Primary Care Association annual conference, 2012-2018.

Introduction: Japan Primary Care Association has launched an international session at annual conference since 2012. Longitudinal characteristics of the presentations were investigated.

Methods: Abstracts of the session were analyzed regarding type of presentation (oral/poster), category (research/clinical case/activity/review), and presenters' geographical location.

Results: The numbers of oral and poster presentations significantly increased. The most frequent presentation was research with cross-sectional survey. Majority of presentations were clinical and less educational research, most of which were by Japanese.

Conclusion: The numbers of presentations in the international session increased, but the session should be used more rigorously to enhance primary care.
