ACORN Arthroplasty Clinical Outcomes Registry National

Purpose #

The Arthroplasty Clinical Outcomes Registry National (ACORN) is the clinical quality registry that provides this study's setting: it collects health-outcome data on patients undergoing elective hip or knee arthroplasty across multiple hospitals, including routine 6-month post-operative patient-reported outcome surveillance by telephone.

Mechanism #

ACORN conducts post-operative data collection 6 months after surgery by telephone, capturing standardised PROMs (satisfaction, operation success, complications, readmission, reoperation, EQ-5D-5L, EQ-VAS, Oxford Hip/Knee Score). Roughly 12% of its participants have limited English proficiency, motivating the registry's use of interpreter proxies (see A-0009ArtifactA-0009Initial AI draftInterpreter proxy survey administration (family or carer, 2-way telephone)A pragmatic, low-cost method for administering patient-reported outcome surveys by telephone to LEP patients, using the patient's own family member or carer as the interpreter proxy in place of a certified professional h…) as a scalable alternative to certified interpreters.

"The study setting was within the Arthroplasty Clinical Outcomes Registry National (ACORN), a clinical quality registry that collects health data on patients undergoing elective hip or knee arthroplasty surgery in multiple hospitals. Post-operative data collection is conducted 6 months post-surgery by telephone and approximately 12% of participants have LEP." (Xue, 2019, p. 2)

ACORN's standard 6-month follow-up questionnaire battery was the instrument set whose proxy-versus-interpreter reliability this pilot assessed.
