Background: Psoriasis is a serious, chronic nonâ€communicable disease. However, the fundamental measure of disease occurrence, incidence, has been scarcely reported globally. There are no previous studies of psoriasis incidence in Latin America. Objective: This study aims to estimate incidence rates of psoriasis in Chile during 2016 and 2017 using an administrative database, the Waiting List Repository. Methods: We examined referrals of psoriasis at onset, made by physicians to dermatologists, evaluated the agreement of diagnosis, and estimated the incidence of the disease considering the eligible population at risk. Results: The referrals corresponded to incident cases of psoriasis 73.3% (95% CI: 66.6% â€“ 79.2%) of the time. National incidence rates of psoriasis were 22.1 (95% CI:21.1â€“23.1) and 22.7 (95% CI:21.8â€“23.6) per 100,000 personâ€years in 2016 and 2017. The most common type of psoriasis was the lateâ€onset type. We observed a high variation in the figures throughout the country, with a range from 0.75 (95% CI: 0.3â€“1.5) to 164.9 (95% CI: 138.6â€“195.1) per 100,000 personâ€years at the Metropolitan and Aysen region, respectively. Conclusions: We describe, for the firstâ€time, the incidence of psoriasis in a Latin American country. Our findings could potential guide collaborations to improve our global understanding of psoriasis in Latin America.
