IMPORTANCE Psychometrically robust patient-reported outcome measures (PROMs) and patientreported experience measures (PREMs) are critical to evaluating quality and performance across health services and systems. However, the adoption and implementation of PROMs and PREMs remain a challenge in many countries. The aim of this guide is to support instrument selection and implementation to measure health system performance.
OBSERVATIONSThe guide is split into 3 step-by-step sections. Step 1: Knowing What to Measure discusses what PROMs and PREMs capture and how they differ from related instruments.Step 2: Choosing the Right Instrument describes the critical psychometric properties of validity, reliability, and responsiveness, and provides resources to support instrument selection and evaluation.Step 3: Mitigating Potential PROM and PREM Implementation Barriers outlines key barriers and supports for instrument implementation at system, service, and individual levels.
CONCLUSIONS AND RELEVANCEThis guide aims to provide practical resources for the identification of psychometrically robust PROMs and PREMs, as well as support for their implementation to drive improvements across health systems globally.
