About ACORNACORN was established in 2012 to provide information on the patient-relevant outcomes of joint replacement surgery. ACORN collects information directly from patients about their expectations of surgery and the actual outcomes of their hip or knee replacement. Specifically, ACORN was designed to provide standardised, reliable and near-complete information from multiple hospitals, and to use this information to drive improvement by informing future decision making by the public, surgeons, and hospitals.
ACORN has developed guidelines and protocols around data collection and dissemination, and a Lead Human Research Ethics Committee has approved the project. In the future, it may be possible to compare the patient reported outcomes across similar sites.
