To explore physicians' and nurses' knowledge, attitudes and experiences of shared decision making (SDM) in rheumatology, to identify barriers and facilitators to SDM, and to examine whether physicians' and nurses' perspectives of SDM differ.A cross-sectional, exploratory, online survey was used. Besides demographic characteristics, healthcare professionals' knowledge, attitudes and experiences of SDM in rheumatology were assessed. Barriers and facilitators to SDM were identified from healthcare professionals' answers. Descriptive statistics were computed and differences between physicians' and nurses' perspectives of SDM were examined with a t-test or Fisher's exact test, as appropriate.Between April and June 2019, 77 physicians and 70 nurses completed the survey. Although most healthcare professionals lacked a full conceptual understanding of SDM, almost all physicians (92%) and all nurses had a (very) positive attitude toward SDM, which was most frequently motivated by the belief that SDM improves patients' treatment adherence. The majority (>50%) of healthcare professionals experienced problems with the application of SDM in clinical practice, mostly related to time constraints. Other important barriers were the incompatibility of SDM with clinical practice guidelines and beliefs that patients do not prefer to be involved in decision making or are not able to take an active role. Modest differences between physicians' and nurses' perspectives of SDM were found.There is a clear need for education and training that equips and empowers healthcare professionals to apply SDM. Furthermore, the commitment of time, resources and financial support for national, regional and organisational initiatives is needed to make SDM in rheumatology a practical reality.
