As part of their mission to improve care for patients by providing meaningful data to participants, the American Joint Replacement Registry (AJRR) developed a comprehensive patient-reported outcome measures (PROM) guide. Fully updated for 2017, it helps to make the most of the AJRR PROM platform—from how to utilize it to capture data to guidance and suggestions on how to start a PROM program. Even if your health institution is not yet participating in the Registry, there are many helpful takeaways in this free guide available at AJRR.net. AJRR is the official registry of AAHKS.
