Objective To develop and test a new instrument for patient self‐reported quality of osteoarthritis (OA) care, and to provide quality indicator (QI) pass rates in a Norwegian OA cohort. Methods The OsteoArthritis Quality Indicator (OA‐QI) questionnaire was developed using published QIs, expert panels, and patient interviews. Self‐reported data were collected from 359 persons in a Norwegian OA cohort, and test–retest reliability and validity were assessed. Separate QI pass rates and summary QI pass rates were calculated. Results The 17‐item questionnaire includes QIs related to patient education and information, regular provider assessments, referrals, and pharmacologic treatment. The patient self‐reported questionnaire was completed with minimal respondent burden. Support for content validity was confirmed by 2 patient research partners and 2 expert panels. All 10 predefined hypotheses relating to construct validity were confirmed. Test–retest kappa coefficients ranged from 0.20–0.80 and the percentage of exact agreement ranged from 62–90%. The mean pass rate for individual QIs was 31% (range 5–49%). The median summary QI pass rate was 27% (interquartile range 12–50%), with lower summary pass rates for nonpharmacologic compared to pharmacologic treatments. Conclusion To our knowledge, this is the first instrument developed to measure patient‐reported QI pass rates for OA care. This study indicates that the OA‐QI questionnaire is acceptable to persons with OA, and its short format makes it suitable for population surveys. The low patient self‐reported QI pass rates in this study suggest a potential for quality improvement in OA care.
