Hsiao et al. conducted a pretest/post test study with RA patients who had outpatient visits using 5 phenotypic groups that clarified patient desires. Clinicians were introduced to the phenotypic groups. The authors found greater evidence of shared decision-making in the post test phase of the study as patients were offered more choices and more visits in which patients vocalized their values and/or preferences and providers were more likely to base their recommendations on patients’ values and/or preferences. Allowing patients to consider a set of preference phenotypes can support shared decision-making.
