Ethics approval and consent to participate
: The Institutional Review Board (IRB) of Harbin Medical University approved this study. Since the survey was anonymous, it was impossible to obtain informed written consent. In this case, an informed consent form was included at the beginning of the questionnaire. Completing the questionnaire was therefore considered ‘informed consent’ for participation in the survey. Confidentiality was maintained for all information collected in the survey.
: Not applicable.
: The authors declare that they have no competing interests.
