Tweeting the meeting: an analysis of Twitter activity at the Royal Australasian College of Surgeons Annual Scientific Congress from 2015 to 2018.

The tweets analysed were mainly informative. Twitter expanded the audience for material discussed at the Annual Scientific Congresses, and the amount of Twitter activity generally increased. It is in the interest of conference organizers to encourage and regulate Twitter use for maximum effectiveness because it is a powerful tool and use is likely to continue increasing in future.
