THU0135 DETERMINANTS OF DISCORDANCE IN PATIENT’S AND PHYSICIAN’S GLOBAL ASSESSMENTS OF DISEASE ACTIVITY OF RHEUMATOID ARTHRITIS IN THE “REAL” STUDY – BRAZIL

Background Discordance between the patient‘s global assessment of disease activity (PGA) and examiner’s global assessment (EGA) has been described in rheumatoid arthritis (RA) (1,2). Understanding the reasons for this discrepancy is essential in the context of treat-to-target treatment strategy. Objectives To assess the determinants of PGA and EGA and factors associated with discordance between them. Methods The REAL study included RA patients from Brazilian public health centers. Clinical, laboratory and outcomes measures were collected. PGA and EGA were rated on a visual analog scale and analyzed. Three groups were defined: no discordance (a difference between PGA and EGA within 3 cm), positive discordance (PGA exceeding EGA by >3 cm), and negative discordance (PGA less than EGA by >3 cm). Multivariate regression analysis was used to identify determinants of PGA and EGA and their discordance. Results 1115 patients (89,4% female, mean age 56.7y and median disease duration of 12.7y) were enrolled. Two factors were associated with PGA in the final multivariate model: one point increase in the pain scale (PS) leads to an increase of 0.62 in PGA; one point increase in HAQ increases by 9,25 points the PGA. The factors associated with EGA were: PS, number of tender and swollen joints (NTJ and NSJ), RF, ESR, HAQ and use of corticosteroids. Discordance between patient and physician was found in 30.52%: positive discordance (PD) in 24.6% and negative discordance (ND) in 5.92%. An increase of one point in the NSJ was associated with a 12% increase in the chance of ND. The chance of PD increased by 90% and 2% for each unit increased in HAQ and PS respectively. Finally, the chance of PD decreased by 3% for each point increased in NTJ and by 15% for each point increased in NSJ. Conclusion In one-third of the assessments, there was disagreement between PGA and EGA (a PD in 80% of them). Pain and function were determinants for patients to estimate disease activity, while swollen joints were the main factor related to a worse examiner’s evaluation. These data show how different can be the perspectives of patients and assistants. References [1] Smolen JS, Strand V, Koenig AS, Szumski A, Kotak S, Jones TV.
