OBJECTIVES: To analyze the willingness for shared decision making (SDM) of rheumatologic patients.   METHODS: All rheumatic patients assisted were invited to participate in this cross-sectional study. A three parts questionnaire was applied (demographic, clinical data and 3 scenarios that simulate a clinical encounter). The scenarios presented the 3 typical steps of a consultation, according to SDM process: 1) Diagnostic statement; 2) treatment options discussion; 3) decision-making. For each step, interviewee was argued 3 questions: a) To identify weather each part was similar to his/her clinical encounter or not; b) to define whether SDM can be a feasible approach; and c) to answer if he/she wanted to be assisted in SDM process, justifying it. Descriptive and multiple correspondence analysis (MCA) techniques were performed to explore data.  RESULTS: Demographic data (N=160): 89% female, 60% < 8 years of school, 48.8% had < 4 years of diagnosis and 30%, > 8 years of diagnosis. Scenario one: 97% would like to have SDM approach on their real clinical practice, justified according to ‘communication empowerment’ (75%) and ‘patients’ right relationship’ (23%). Scenario two: 65% declared that they like SDM purpose, justifying it according to ‘communication empowerment’ (63%)’. Scenario three: 65% of the participants never took part in the decision process. However, 98% would like to do it, justifying according to ‘patients’ right relationship’ (30%), and ‘communication empowerment’ (28%) but 13% answered that the whole decision belongs to the physician. MCA plot illustrates that for diagnostic statement ‘communication empowerment’ correlates to low literacy. To understand treatment option, communication empowerment and patient’s right was correlated with those who had < 4 years of diagnosis; and > two rheumatic conditions.   CONCLUSIONS: Communication empowerment and patient’s right were the most common reasons for the willingness for SDM.
