Ethics approval and consent to participate
: The study was based on a data protection concept approved by the German Statutory Pension Insurance. Every participating peer involved in the project was informed about the study, received project information and gave written consent to participate. All study participants in the pre-test and inter-rater reliability phases operated exclusively with anonymous medical experts’ reports. As the peer review was performed with an online survey only anonymised data were processed and evaluated by the researchers in charge. By analysing only anonymised data an ethic approval was not required. This approach complies with national ethical guidelines as studies with anonymised data (no code list available, no personal reference possible) are not subject to ethical consultation [CitationRef removed].
