We aimed to determine the performance of the 2017 European League Against Rheumatism/American College of Rheumatology (EULAR/ACR) classification criteria for idiopathic inflammatory myopathies (IIMs) in a cohort of Chilean patients. This single-center retrospective study included 151 patients with a clinical diagnosis of IIM. Patients were classified according to the 2017 EULAR/ACR classification criteria for IIM, and its performance was compared to the Bohan & Peter (B&P) classification criteria. A total of 135 patients (89.4%) met the EULAR/ACR criteria, and 140 (92.7%) patients met the B&P criteria. A total of 130 patients had IIM according to both the criteria; concordance rate was 29.2% for definite IIM, 6.2% for probable IIM, and 1.5% for possible IIM. The kappa coefficient of agreement was weak between the 2 classification criteria (κ = 0.39, SD 0.15-0.64). Against gold standard expert physician's diagnosis, sensitivity, and specificity of EULAR/ACR criteria was 0.86 and 0.85 to diagnose dermatomyositis, respectively, and 0.73 and 0.87 to diagnose polymyositis. The EULAR/ACR criteria showed good sensitivity and identified more patients with probable or definite IIM than the B&P criteria in a single-center cohort of patients with IIM in South America. The sensitivity of the EULAR/ACR criteria was slightly higher in patients with dermatomyositis, but lower in patients with polymyositis, than that of the B&P criteria.
