Linking Hip Disability and Osteoarthritis Outcome Score-Physical Function Short Form (HOOS-PS) and Patient-reported Outcomes Measurement Information System Physical Function (PROMIS PF) scores enables data aggregation. Crosswalks are validated for group-level conversions, not individual patient data.
Area of Science:
- Orthopedics
- Health Outcomes Research
- Biostatistics
Background:
- Patient-reported outcome measures (PROMs) are crucial for research and clinical care.
- Linking different PROMs facilitates data aggregation and comparative analysis.
- Hip osteoarthritis management benefits from standardized outcome assessment.
Purpose of the Study:
- To develop and validate methods for linking scores between the Hip Disability and Osteoarthritis Outcome Score-Physical Function Short Form (HOOS-PS) and the Patient-reported Outcomes Measurement Information System Physical Function (PROMIS PF).
- To enable data aggregation across studies using these different physical function measures.
Main Methods:
- A retrospective study analyzed 7,369 HOOS-PS and PROMIS PF measure pairs from 3,382 hip osteoarthritis patients (2017-2020).
- Four linking methods, including equipercentile and item response theory (IRT)-based approaches, were compared.
- The Stocking-Lord IRT method was selected as the optimal crosswalk, with HOOS-PS item parameters estimated on the PROMIS metric.
Main Results:
- HOOS-PS and PROMIS PF scores demonstrated strong correlations (r ≈ 0.82).
- Assumptions for equipercentile and IRT linking methods were met.
- Sensitivity analysis confirmed the robustness of crosswalk estimates across nonsurgical, preoperative, and postoperative patient groups.
Conclusions:
- Validated crosswalks allow for group-level score conversion between HOOS-PS and PROMIS PF metrics, aiding data aggregation.
- Individual patient-level score conversion is not recommended due to potential for increased error.
