It would be worth looking into the seniority of the doctors attending the meetings. This is purely anecdotal, but my town hosts some meetings and conventions, including doctors, and I've been hired by those events as a musician.
I'm always struck by how young the attendees are. They look like kids. It may be that meetings are more of an attraction for people trying to build their careers, make connections, and have a free vacation, whereas the senior doctors are happy to stay at home and man the fort, plus they have the usual obligations of older workers, such as families.
This is also the case at my techie day job: Most of the interest in attending meetings is among the junior engineers.
