Can numerical rating scales of disease impact be used as targets for patient-centred management in rheumatoid arthritis?
Authors' conclusion
Quantified impact targets defined at population level are not appropriate for individual patient care.
Study context
- Population
- Consecutive patients with RA asked the maximum acceptable impact severity in the seven RAID domains
- Participants
- 299 patients
- Outcome
- Dispersion of individual target values (adequacy of population-based reference values) and their stability between visits (ICC)
Methodological detailsconsecutive patients, two consecutive visits
- Consecutive patients
- Two consecutive visits
Main finding
As reported in the abstract
Dispersion of targets wide
CV>0.68
Reliability between visits poor in all domains (ICCs)
0.37-0.47
Patients selecting the same target value in the 2 visits
25-30%
Observational data: associations, not effects.
Further findings
Co-factors of stability (socio-demographic, clinical, psychological)
- No explanatory factors for (non-)stability identified
