: Hospitals distributed an online link or a QR code for the study survey to the clinical staff via email or pay slip. The invitation to participate in the anonymous online survey contained information on the procedure and objectives of the study, the voluntary nature of study participation and data protection. Since there was no direct contact with the respondents and the survey was anonymous, we were not able to obtain a "classic" personal consent form. If the addressees agreed to participate in the study, they could click on the link or scan the QR code. As usual in such anonymous surveys, participation after detailed information had been provided was interpreted as declaration of consent. All methods were carried out in accordance with relevant guidelines and regulations. The consent procedure was approved by the Ethics Commission of the Charité – Universitätsmedizin Berlin and the Data Protection Officer of the Charité – Universitätsmedizin Berlin.This study received the approval both of the Ethics Commission of the Charité – Universitätsmedizin Berlin (EA1/062/18) and the Data Protection Officer of the Charité – Universitätsmedizin Berlin.
