The development and utility of a multicriteria patient decision aid for people contemplating treatment for osteoarthritis

BACKGROUND: There are a range of treatment options for osteoarthritis (OA) of the knee and hip, each with a unique profile of risks and benefits. Patient decision aids can help incorporate patient preferences in treatment decision‐making. The aim of this study was to develop and test the utility of a patient decision aid for OA that was developed using a multicriteria decision analytic framework. METHODS: People contemplating treatment for OA who had accessed the website myjointpain.org.au were invited to participate in the study by using the online patient decision aid. Two forms of the patient decision aid were created: A shorter form and a longer form, which allowed greater customization that was offered to respondents after they had completed the shorter form. Respondents also completed questions asking about their experience using the patient decision aid. RESULTS: A total of 625 self‐selected respondents completed the short‐form and 180 completed the long‐form. Across both forms, serious side effects, pain and function were rated as the most important treatment outcomes. Most respondents (64%) who completed the longer form reported that using the tool was a positive experience, 38% reported that using the tool had changed their mind and 48% said that using the tool would improve the quality of their decision‐making. CONCLUSIONS: Overall, the findings suggest that this patient decision aid may be of use to a substantial number of people in facilitating appropriate treatment decision‐making. PATIENT OR PUBLIC CONTRIBUTION: Service users of myjointpain.org.au were involved through their participation in the study, and their feedback will guide the development of future iterations of the tool.
