Abstract
Objective Characterization of the stages that patients with JIA pass until diagnosis, and analysis of the different causes that lead to a delay in JIA diagnosis in Israel.
Methods The study is a retrospective, cohort study that was done in eight pediatric rheumatology centers in Israel. All patients diagnosed with JIA between October 2017 and October 2019 were included in the study. Demographic, clinical, and data regarding the referral's physicians were collected from hospital and community medical charts.
Results Of 207 patients included in the study, 201 cases were analyzed, 71.1% of the population were female. Patients on average, were evaluated during the diagnostic process by three (3.1) different physicians. In most cases, they initially met with a pediatrician in the community setting (61.2%), and later, most commonly referred to a rheumatologist by the community pediatrician (27.8%). The median time until diagnosis was 56.0 days (range: 1.0-2451.0 days). Patients diagnosed with polyarticular and enthesitis related-/spondyloarthritic (ERA/SPA) JIA subtypes had the longest period until diagnosis (median: 115.5 and 112.0 days, respectively). Younger age correlated with a quicker diagnosis, and females were diagnosed earlier compared to males. Fever at presentation significantly shortened the time to diagnosis (P<0.01), whereas involvement of the small joints/sacroiliac joints significantly lengthened the time (P<0.05).
Conclusion This is the first nationwide multicenter study that analyzes obstacles in the diagnosis of JIA in Israel. Raising awareness of JIA, especially for patients with ERA/SPA, is crucial in order to avoid delays in diagnosis and treatment.
