Misuse of Coauthorship in Medical Theses in Sweden

The aim of this study was to explore experiences of authorship issues among persons who have recently received their doctoral degree in medicine in Sweden. A survey was mailed to all who received their PhD at a medical faculty at a Swedish university the first half of 2016. Questions concerned experiences of violations of the first three authorship criteria in the Vancouver rules and of misuse of authorship order in the articles of their thesis, and the respondents' attitudes to these matters. The questionnaire was returned by 285 respondents (68%). According to the majority (53%), the Vancouver rules were not fully respected in the articles of their thesis. A vast majority (97%) found it important that authorship issues are handled correctly, but only 19% responded that their department has a clear and consistently applied policy. We conclude that authorship guidelines are frequently disrespected at medical faculties in Sweden. The universities seem to provide limited support on authorship issues.
