Abstract

Background: The effectiveness of biologics for improving long-term outcomes in patients with Crohn's disease [CD] is still controversial. In this nationwide study, we aimed to evaluate trends of long-term outcomes in all CD patients in Israel during the biologics era. Methods: Trends of outcomes were analysed using data from the four Israeli health maintenance organisations, covering 98% of the population; joinpoint regression models were used to explore changes of these trends over 2005 to 2019. Results: A total of 16 936 patients were diagnosed with CD in Israel since 2005 (2932 [17%] paediatric onset, 14 004 [83%] adult onset) with 114 947 person-years of follow-up. The cumulative rate of any CD related surgery was 5%, 9%, 11%, and 14% at 1, 3, 5, and 10 years from diagnosis. The increase in use of biologics was sharp (from 8.9% to 36%; average annual percent change [AAPC], 14.3%), and the time to biologics was shorter in recent years (median time of 4.8 [1.9-8.1] years in those diagnosed in 2005-2008 compared with 0.5 [0.2-1.1] years in those diagnosed in 2015-2018; p < 0.001). A significant decrease was noted in the hazard of hospitalisations (1.3 [0.1-4.6] years compared with 0.2 [0.02-0.9] years; p < 0.001), steroid dependency (1.5 [0.2-5.4] years compared with 0.1 [0.02-0.4] years; p < 0.001), and intestinal surgeries [4.7 [1.6-8.2] years compared with 0.6 [0.2-1.4] years; p < 0.001), but not of perianal surgery (4.2 [1.1-7.7] years compared with 0.6 [0.2-1.4] years; p = 0.2). Outcomes were consistently worse in paediatric onset compared with adults. Conclusions: The rates of hospitalisations, steroid dependency, and intestinal resections decreased in association with increased use of biologics both in children and in adults, but not the rate of perianal surgeries.
