German medical students must conduct a research project and write a dissert
ation in order to receive the title "Doctor." However, the dissertation is
not required to graduate, enter a residency, or practice medicine. About 90
% of practicing physicians hold the title "Doctor"; a career in academic me
dicine almost always requires it. Although no convincing evidence supports
the usefulness of the dissertation, many regard its completion as important
to maintaining a high level of scientific competence and patient care. In
recent years, the number of successfully completed dissertations has declin
ed. Lack of time during medical school, the perceived irrelevance of the di
ssertation to medical practice, and the poor design of many projects may be
at least part of the problem. There is also increasing evidence that condu
cting research frequently delays graduation and may affect clinical skills
because students working on projects attend fewer classes, ward rounds, and
clinical tutorials and do not spent sufficient time preparing for examinat
ions. The scientific value of students' research has also been criticized;
critics point out that students do not have enough time or experience to cr
itically analyze methods and data, and they often are not properly supervis
ed. European unification will probably lead to standardized requirements fo
r medical education and research. The authors hope this will eliminate the
dissertation requirement in Germany.
