Determinants of discordance in patients' and physicians' rating of rheumatoid arthritis disease activity.

ABSTRACT:

Objective

To assess the determinants of patients' (PTGL) and physicians' (MDGL) global assessment of rheumatoid arthritis (RA) activity and factors associated with discordance among them.

Methods

A total of 7,028 patients in the Quantitative Standard Monitoring of Patients with RA study had PTGL and MDGL assessed at the same clinic visit on a 0-10-cm visual analog scale (VAS). Three patient groups were defined: concordant rating group (PTGL and MDGL within ±2 cm), higher patient rating group (PTGL exceeding MDGL by >2 cm), and lower patient rating group (PTGL less than MDGL by >2 cm). Multivariable regression analysis was used to identify determinants of PTGL and MDGL and their discordance.

Results

The mean ± SD VAS scores for PTGL and MDGL were 4.01 ± 2.70 and 2.91 ±
