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 from employees and not from patients. Furthermore, survey participation of hospital employees was completely anonymous and entirely on a voluntary basis. For these reasons, no approval was required by the ethics committee nor any authorisation by the commissioner for data protection by the national and cantonal laws nor were these recommended by the medical-ethical guidelines for scientific integrity of the Central Ethics Committee and the Swiss Academies of Sciences.

: Explicit consent of study participants (companies) or survey respondents (employees) for the publication of any study results and research findings was either not required and necessary or contractually regulated.
