Do All Authors Need to Attend a Medical Conference?

No. In most conferences only one author (the presenting author) needs to attend and register, although rules vary and some meetings require that at least one author be present for the abstract to be included in the programme. Check the conference's policy.

Typical rules

• A presenting author is nominated at submission and must register and present.
• Co-authors do not need to attend, but they are still listed on the abstract.
• Virtual or pre-recorded presentations may be allowed.
• If the presenter cannot attend, some conferences allow a substitute from the author group if you tell the organisers by a deadline.
• No-shows may result in withdrawal of the abstract from the programme or abstract book.

Good practice for the team

1. Agree who will present at the time of submission.
2. Make sure the presenter can attend (funding, visa, schedule).
3. Share the poster or slides with all co-authors before the meeting.
4. Tell co-authors about the presentation time.
5. List the presenting author correctly on your CV and mark the presenter where your format allows.
6. Update co-authors afterward on feedback and next steps.

Illustrative example

Invented for teaching. A student leads a project with a team in three countries. She will present the poster, and her co-authors review it in advance. One co-author attends virtually for the question-and-answer session, as the conference allows.

Credit and visibility

Whether or not a co-author attends, their name stays on the abstract and the presentation. Make sure the slides or poster list every author and affiliation accurately, and consider asking a co-author to take part in a virtual question session if the format allows. If you are the presenter, share the feedback you receive with the whole team, since it may shape the manuscript.

Common pitfalls

• Not telling co-authors that the abstract was accepted.
• Failing to arrange a substitute if the presenter cannot attend.

Key takeaways

• One presenting author is usually enough.
• Communicate and follow the conference's rules.
