Background Discordance between patients' and physicians' ratings of disease activity is frequent. We have previously shown this discordance occurs in around 28% of visits in early axSpA though repeated discordance (over several visits) is less frequent (1).

Objectives To assess in patients with early axSpA, the impact at 3 years of repeated discordance on treatment prescription, functional incapacity and remission.

Methods DESIR (Devenir des Spondyloarthropathies Indifférenciées Récentes) is a French, multicenter, longitudinal cohort of patients with early inflammatory back pain suggestive of axSpA (2). Patient and physician global assessment (respectively PGA and PhGA) were rated on a 0–10 numeric scale, every 6 months during 2 years then at 3 years. Only patients with all data available for PGA and PhGA for each of the 6 visits were included. Repeated discordance was defined as an absolute difference |PGA–PhGA|≥3/10 for at least 3 of the 6 visits (i.e., at least half of the visits). Univariable and multivariable logistic models were used to determine if repeated discordance was associated at the 3 years timepoint, with prescription of TNFi, functional incapacity defined as HAQ>0.5, and remission defined as ASDAS-CRP<1.3.

Results Of 401 patients, mean age 34.6±8.7 years, mean symptoms duration 17.8±10.7 months, 219 (54.6%) were female and mean ASDAS-CRP at baseline 2.7±1.0. At 3 years 140 (34.9%) patients had been prescribed a TNFi, 172 (43.2%) had HAQ>0.5 and 89 (25.1%) were in remission. Over the 6 visits, mean PGA was higher than mean PhGA with a mean absolute difference of 0.8±2.2 points. Discordance concerned 110 (27.4%) patients at baseline and repeated discordance concerned 92 (22.9%) patients. In multivariable logistic regression, after adjusting on the others significant factors (which included MRI sacro-iliitis, HLA-B27 and ASDAS-CRP at baseline), repeated discordance was associated with more functional incapacity (61% vs 38%, odds ratio, OR 2.85 [95% CI 1.49–5.62]) and less remission (10% vs 30%, OR 0.38 [0.15–0.85]) but not more TNFi use (34% vs 35%, 1.39 [0.78–2.54] p=0.27).

Conclusions In early axSpA, repeated discordance concerned 22.9% of patients confirming the frequency of this situation. Repeated discordance was associated with worse outcomes at 3 years, even after adjustment of other factors including baseline ASDAS, indicating for the first time that discordance may indeed reflect an unsatisfactory management of medical care leading to worse outcomes. Future studies should concentrate on understanding the reasons of patient-physician discordance for disease activity in axSpA.
