Key Points

  • Patient-reported outcomes (PROs) assess how a disease affects patients’ health status—their symptoms, functional limitations, and quality of life. Attributes of health status measures include:
    • Validity: Does the instrument capture what is important to patients (content)? Does it measure what it is supposed to (criterion)?
    • Reliability: Are the results the same when given repeatedly to stable patients?
    • Responsiveness: Do the results reflect changes in patients’ disease status?
    • Interpretability: What does a given score or change in score mean?
    • Translations: Are linguistically and culturally appropriate translations available?
  • The Kansas City Cardiomyopathy Questionnaire (KCCQ) is a valid, reliable, and responsive instrument used to measure health-related quality of life for patients with heart failure. Treatment goals include helping patients live longer and feel better.
  • PROs capture a key outcome from patients’ perspectives, and the integration of PROs into development programs should occur early.

Discussion Themes

The challenge of new metrics includes how to interpret scores at a single point in time and when scores change. Metrics need to be translated to a clinical framework and interpreted before they can be used to predict patient outcomes.

What about using accelerometers and other activity monitors linked to GPS data?
