Patient-Reported Outcomes Measurement Information System (PROMIS) offers superior physical function assessment in orthopaedics. PROMIS improves measurement accuracy and reduces patient burden compared to older methods.
Area of Science:
- Orthopaedic research
- Health outcomes measurement
- Biostatistics
Background:
- Patient-reported outcome measures (PROMs) are vital for assessing health status.
- Traditional orthopaedic PROMs often have limited scope and high administrative burden.
- Existing measures may not be suitable for diverse patient populations.
Purpose of the Study:
- To introduce the Patient-Reported Outcomes Measurement Information System (PROMIS) as an advancement over traditional PROMs.
- To highlight PROMIS's development using item response theory for efficient health trait estimation.
- To evaluate the utility of PROMIS Physical Function measures in orthopaedic populations.
Main Methods:
- Development of PROMIS using item response theory (IRT).
- Creation of targeted item banks for assessing upper and lower extremity physical function.
- Validation of PROMIS in patient cohorts with foot and ankle, upper extremity, and spine disorders.
Main Results:
- PROMIS demonstrated improved measurement characteristics compared to legacy measures.
- PROMIS significantly reduced both patient and administrative burden.
- Validated effectiveness in diverse orthopaedic patient groups.
Conclusions:
- PROMIS Physical Function measures are effective tools for assessing orthopaedic outcomes.
- PROMIS offers superior measurement properties and efficiency in key orthopaedic populations.
- PROMIS represents a significant advancement in patient-reported outcome measurement for orthopaedics.
