As part of our goal to develop IIM-specific PROM, the Outcome Measures in Rheumatology (OMERACT) Myositis special interest group sought to determine which aspects of disease and its effects are important to patients and healthcare providers (HCP). Methods Based on a prior qualitative content analysis of focus groups, an initial list of 24 candidate domains was constructed. We subsequently conducted an international survey to identify the importance of each of the 24 domains to be assessed in clinical research. Patients with IIM, their caregivers, and HCP treating IIM completed the survey. Results In this survey, a total of 638 respondents completed the survey, consisting of 510 patients, 101 HCP, and 27 caregivers from 48 countries. Overall, patients were more likely to rank “fatigue,” “cognitive impact,” and “difficulty sleeping” higher compared with HCP, who ranked “joint symptoms,” “lung symptoms,” and “dysphagia” higher. Both patients and providers rated muscle symptoms as their top domain. In general, patients from different countries were in agreement on which domains were most important. One notable exception was that patients from Sweden and the Netherlands ranked lung symptoms significantly higher compared to other countries including the United States and Australia (mean weighted rankings of 2.86 and 2.04 vs 0.76 and 0.80, respectively; p < 0.0001). Conclusion Substantial differences exist in how IIM is perceived by patients compared to HCP, with different domains prioritized. In contrast, patients’ ratings across the world were largely similar.
