Ethics approval and consent to participate
: In a cover letter, appearing both in the magazine where the survey was published as well as in the online survey, participants were informed about the purpose and the nature of the study, the entirely voluntary and anonymous data collection and thus anonymous publication of aggregated survey results. They were informed that consent to participation would be assumed if the online survey was started or the paper questionnaire returned. As data collection was anonymous and the survey did not contain sensitive questions, no ethics approval was considered necessary according to the Professional Code for Physicians in Germany (https://www.bundesaerztekammer.de/fileadmin/user_upload/downloads/pdf-Ordner/MBO/MBO-AE_EN_2018.pdf). We obtained the approval for the implementation of this survey from the Data Protection Officers of the Robert Koch Institute.
