Summary
This study validates the use of Patient-Reported Outcomes (PROs) in hip registries, confirming four PROs (OHS, HOOS, EQ-5D, SF-12) are suitable. It also details a validated Danish translation of the OHS for improved data quality in orthopedic research.
Area of Science:
- Orthopedics
- Medical Informatics
- Health Outcomes Research
Background:
- Patient-Reported Outcomes (PROs) are increasingly used in orthopedics and joint registries.
- However, comprehensive validation and adaptation of PROs for specific registry contexts are often lacking.
- This necessitates rigorous examination of PRO feasibility, data capture, and interpretation within registry settings.
Purpose of the Study:
- To assess the feasibility of four common PROs (OHS, HOOS, EQ-5D, SF-12) in a hip arthroplasty registry.
- To translate, cross-culturally adapt, and validate a Danish version of the Oxford Hip Score (OHS).
- To evaluate data capture methods and establish patient sample size requirements for subgroup analyses, and to estimate minimal clinically important improvement (MCII) and patient-acceptable symptom state (PASS).
Main Methods:
- Feasibility of OHS, HOOS, EQ-5D, and SF-12 assessed in 5,747 hip arthroplasty patients.
- Danish OHS translation, adaptation, and validation (2,278 patients).
- Data capture validation using Optical Mark Recognition (OMR) compared to manual entry (200 patients).
- Sample size calculations for subgroup analyses and estimation of MCII/PASS (1,335 patients).
Main Results:
- OHS, HOOS, EQ-5D, and SF-12 demonstrated high feasibility in the hip registry, with minor differences in effects.
- The validated Danish OHS showed excellent reliability and validity for THA patients.
- OMR data capture was efficient and accurate, comparable to double-key manual entry.
- Calculated sample sizes for subgroup analyses ranged from 51 to 1,566 patients.
Conclusions:
- The HOOS, OHS, SF-12, and EQ-5D are appropriate for hip registry use.
- The translated Danish OHS is a valid and reliable tool for outcome studies in hip arthroplasty.
- Optimized data capture and understanding of sample size needs enhance registry data quality and research potential.
- Estimated MCII and PASS values provide benchmarks for interpreting treatment outcomes in THA.
