Background To better enable a better understanding of disease worsening or flare (F) in Rheumatoid Arthritis (RA) core domains for assessment of flare have been identified by patients (pts) and health care professionals through Delphi exercises. Two of these include patient (pt) identification of swollen and tender joints1.
Objectives To evaluate concordance between patient and rheumatologist assessments of swollen and/or tender joints during flare in early RA.
Methods Patients in Canadian early ArThritis CoHort (CATCH) completed the OMERACT preliminary flare questionnaire (PFQ) at study visits between 11-2011and 01- 2012. Pts self assessments of number of tender and swollen joints (42 joints – tender and swollen) were compared with joint counts routinely conducted by their rheumatologists (at same visit).
Results 263 CATCH pts completed the PFQ during the study period. 30% (79) reported a flare (F). Mean age (SD) in F group (gp) was 52.3 (16.6); 77% were female, 68.4% were RF+. Patients reported significantly higher tender joint counts than those reported by their rheumatologists for all 42 joints, 10 large joints and upper extremity joints (Table). There was a trend (p=0.08) for higher patient swollen joint counts for all 42 joints; other differences between patients and providers for swollen joints were not statistically significant.
Conclusions In patients with early RA, pt and MD SJCs were similar, but pts reported a higher number of affected joints. Differences in SJCs between groups were not statistically significant. These data highlight that ERA pts in a flare are aware of their joint involvement. Patient joint counts need to be considered in measures looking at worsening of disease activity.
