ObjectiveCurrent recommendations suggest that patients with newly presenting arthritis suspected of Rheumatoid Arthritis (RA) should undergo routine radiographs of hands and feet (X‐HF) as the presence of RA‐associated erosions might be of diagnostic and prognostic value. Our objective was investigate the prevalence, diagnostic and prognostic value of RA‐associated erosions seen on routine X‐HF in a large, recent cohort of newly presenting arthritis patients.MethodsA retrospective cohort study was performed between 2016‐2019 in patients with newly presenting arthritis suspected of RA. Patients were included if arthritis was present at diagnosis, Rheumatoid Factor and Anti‐Citrullinated Protein Antibodies were measured, RA was noted in the differential diagnosis, and routine X‐HF were conducted. Outcomes were the prevalence of ≥1 RA‐associated erosion, and whether diagnostic or prognostic classification were changed by erosivity. Seronegative patients, patients without Acute Phase Reactants (APR) and patients with longer symptom duration were analyzed as subgroups.ResultsRA‐associated erosions were found in 32/724 patients (4.4%, CI 3.1‐6.2%). Erosions led to a change of diagnostic classification in two patients (0.3%, 95%CI 0.01‐1.1%) and changed prognostic classification in three patients (0.4%, 95%CI 0.1‐1.3%). Seronegative patients and patients without elevated APR had significantly lower prevalence of erosions (χ2 9.4, P=0.002, χ2 6.5, P=0.01). Longer symptom duration was not associated with a different prevalence of erosions (χ2 0.4, P=0.81).ConclusionThe recommendation of conducting routine X‐HF in patients with newly presenting arthritis suspected of RA might be reconsidered, due to low prevalence of early erosive disease and lack of diagnostic and prognostic value.image
