Shared Decision-Making and Patient Satisfaction in Japanese Rheumatoid Arthritis Patients: A New "Preference Fit" Framework for Treatment Assessment.

Abstract

IntroductionWe have developed a new framework to assess shared decision-making (SDM) as a tool to improve patient satisfaction. This framework is based on a “preference fit” index that relates SDM to patient treatment preferences and patient satisfaction in a sample of rheumatoid arthritis (RA) patients in Japan.MethodsWe surveyed 500 RA patients in Japan and explored the interactions between the treatment preference fit index, SDM, and overall patient satisfaction.ResultsOur new preference fit index reveals significant impact on patient satisfaction: the better the fit between SDM and patient preferences, the higher the patient satisfaction with the current treatment. Patients treated with biologic agents were more satisfied. Patients suffering from depression or migraines scored significantly lower both on our preference fit measure and for overall patient satisfaction.ConclusionThe association between depression and a low treatment preference fit suggests that depression may pose challenges to SDM and that doctors in Japan are less attuned to the SDM preferences of depressed patients.FundingJanssen Pharmaceutical KK.
