Treat-to-target and shared decision-making in systemic lupus erythematosus from the patients' perspective: results from an international patient survey.

Objectives: Treat-to-target (T2T) is being recognised as a promising concept to significantly improve the outcomes of patients with systemic lupus erythematosus (SLE). Despite its success being closely tied to patients' involvement, the patients' perspective regarding T2T has not been evaluated. We aimed to investigate patients' attitude towards T2T and their involvement in treatment decisions.
