Measuring outcomes

This branch covers what health research measures and how those measurements are interpreted, divided by the measurement question: choosing a health outcome, assessing measurement quality and using patient-reported measures. It leaves endpoint choices for particular trial designs, statistical tests, economic utilities and instrument translation to neighbouring branches.

• Measuring health outcomes — defining health and expected benefits, choosing a target metric, observing change and using the results
• Measurement quality — precision, reliability, accuracy, validity, scale meaning, measurement reporting, questionnaire design and agreement
• Patient-reported outcomes — instruments, health-related quality of life, meaningful change, electronic collection and regulatory expectations for patient experience data
