For the ratings, median, mean and SD were calculated for all participants using SPSS V.21.29 Demographic data were analysed accordingly, except for nominal items where we calculated frequencies. Consensus was examined by calculating distributions of answers per tertile (1–3; 4–6; 7–9) in comparison with Zill et al.14 We compared different subgroups due to potential differences in using the healthcare system including age groups (18–30 (young); 31–65 (middle aged); over 65 (older)), way of participation (mail vs online) and morbidity (single disease vs multi-morbidity). Open answers were analysed, summarised by two researchers and the student assistant (SZ, EC, Tanja Kloster) and reviewed in a group discussion (SZ, EC, IS).
