The design and realization of the study were approved by the ethics committee of the General University Hospital in Prague as individual research (Ref. 915/20 S–IV). All respondents included in this study confirmed informed consent in the questionnaire. The informed consent included a brief description of the research and information on stakeholders. The rights and anonymity of the respondents were also emphasized. The respondents were informed that there were no right and wrong answers, only attitudes, and they were asked to complete the questionnaire responsibly. At the end of the informed consent, there was a question item regarding the reading and understanding of the previous text, in which the respondents were assured that everything is in accordance with the current legal decree, and whether they agreed to participate in the research. An email address was provided in the informed consent. All aspects in this research were conducted with respect to the seventh revision of the World Medical Association–Declaration of Helsinki [106] and the second revision of the Farmington Consensus [107].
