Patient Reported Outcomes
Patient reported outcomes are an important component of the overall assessment of subjects in clinical studies. IMACS has agreed to incorporate patient-reported outcomes in all myositis trials and clinical studies. This includes a generic health-related quality of life measure that is age appropriate (adult vs. pediatric), and a measure of fatigue, which is under development.
These and other quality of life tools, as well as their validation, and performance characteristics, have been reviewed in the following article:
