Ethics approval and consent to participate

: The introductory text of the survey informed the participants that the survey was part of a scientific project and that the results were to be presented anonymously. Participation was optional. Approval from the institutional review board or equivalent committee(s) was not obtained, as the online survey represented non-interventional research with anonymised data that included health care professionals, not patients. There is no legal obligation to obtain ethics approval for this type of research in Germany. Consent for participation was assumed when participants submitted their completed questionnaire online. No cookies were used to assign a unique user identifier to each respondent’s computer. The respondents’ IP addresses were not available in the SurveyGrid analysis. Thus, it was not possible for the assessors to allocate individual respondents. No other techniques to analyse the log file for identification of multiple entries were used. No incentives were offered for participation.
