Ethics approval and consent to participate
: The study is observational and not clinical or experimental and did not involve medical records or human tissues. Data used were collected from hospitals and clinics, but survey respondents were employees and not patients. Furthermore, survey participation was completely anonymous and entirely on a voluntary basis. For these reasons, informed and explicit consent from hospital employees was not needed or obtained but implicitly given by participating voluntarily in the survey.In Switzerland, under national and cantonal laws and for this kind of data collection, no formal approval or authorisation is required or will be issued, neither by the national ethics committee nor by the cantonal commissioner for data protection. These are not even recommended by the medical-ethical guidelines for scientific integrity of the Central Ethics Committee and the Swiss Academies of Sciences.
