Many factors are associated to the delay in the diagnosis of juvenile idiopathic arthritis (JIA), some of them related to the disease and other to the difficulty in referring patients to specialists. The Early Detection of Arthritis Questionnaire (EDA-12) was designed to be used as an auxiliary tool for screening of suspect cases in general practice. However, its reliability was tested only in a small number of subjects.
To assess the reliability of EDA-12 in the detection of suspect cases referred to outpatient pediatric rheumatology reference clinics in 3 large urban areas.
EDA-12 (score range 012) was applied to parents of children (0 18 y) who sought spontaneously or were referred for evaluation in 7 outpatient pediatric rheumatology clinics. Diagnostic suspicion was recorded in the first consultation (initial diagnosis), and definitive diagnosis was recorded after, at least, 6-month period of follow-up.
Six hundred and sixty patients (57% girls) were included, with age (mean) of 9 years-old. JIA initial diagnosis was performed in 12% of the consultations, being also observed in the definitive diagnosis (12% of the consultations), with a high agreement between the first suspicion and the diagnostic confirmation (kappa coefficient = 87.2%). A ROC curve was used in the assessment of a score able to distinguish JIA children from non-JIA children, being obtained a value of 5 (five) in the first consultation, with sensibility of 93% and specificity of 76%.
The EDA-12 has demonstrated reliability for discrimination of suspect cases of JIA and reinforces its relevance as an auxiliary tool in the first medical consultation.
