Dr. med. Title

Hello!

I have this one question about receiving the dr. med. title in Switzerland (also Germany). As I understand most of the medical students start working on their doktorarbeit during the studies. Where I am from, there is no such thing as a doktorarbeit and most students work and write research for other reasons.

I am wondering whether it is possible to get your published research articles recognized and that way receive the dr. med. title withouth doing research in Switzerland university hospitals for example?
