Background

Patient reported outcome measure (PROMs) facilitate patient-centred care by allowing the clinician to focus on what is important to the patient, and the systematic collection of this data can guide areas for quality and safety improvements.1 The “Patient-Reported Outcomes Measurement Information System® (PROMIS) 29 tool has recently been adopted as a quality of life measure in Australia, including in the Concord Hospital Osteoarthritis Chronic Care Program (OACCP).2 It is recommended by the Australian Commission On Safety And Quality In Health Care. However, there is little data validating its use in the Australian population.3 PROMIS profile tools contain 7 domains of self-reported health: depression; anxiety; physical function; pain interference; fatigue; sleep disturbance; and ability to participate in social roles and activities, with a fixed number of items per question scored using a 5-point Likert Scale. This prospective cohort study aims to validate PROMIS-29 as a PROM in an Australian population with osteoarthritis.

Methods

Approximately 100 Australian adults over the age of 40 with a diagnosis of hip or knee OA will be invited to complete PROMs at week 0 (enrolment in the OACCP), week 1 and month 3.  The primary endpoint will be the test-retest reliability of the PROMIS-29 tool as a PROM. The secondary endpoints will be construct and criterion validity of the PROMIS-29. Convergent and discriminant validity will be determined by comparing overall PROMIS-29 scores and individual domains and the correlation of the PROMIS-29 with two other patient reported outcome measures, the Hip dysfunction and Osteoarthritis Outcome Score (HOOS) or Knee injury and Osteoarthritis Outcome Score (KOOS) and the EQ-5D-5L. Criterion validity will be assessed by comparing the PROMIS-29 score with objective measures of function; the timed up-and-go test (seconds) and 40 metre walk test.
