Declarations

:

: This study was carried out in consideration of the Declaration of Helsinki. It was approved by the ethics committee of the University of Lübeck on January 10, 2018 (File reference 17–374). This ethical approval comprised that the need for obtaining explicit written consent from the participants was not felt necessary as this paper-based survey was planned and executed as collection of anonymous data. Participants - patients as well as health care team members - were fully informed in a study information form about the consequences of participation, especially that the return of the questionnaires would result in data publication and will be seen as informed consent for participation. In line with the ethical approval, the return of the completed questionnaire was seen as consent to participate. All returned questionnaires were filed, numbered consecutively with an identification number and entered into a SPSS database.
