Psoriasis is a serious and chronic noncommunicable disease. However, the fundamental measure of disease occurrence, the incidence, has been scarcely reported globally. There are no previous studies of psoriasis incidence in Latin America.
To estimate the incidence rates of psoriasis in Chile during 2016 and 2017 using an administrative database, the Waiting List Repository.
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.
In most cases, the referrals corresponded to incident cases of psoriasis (73.3%; 95% CI: 66.6-79.2). The national incidence rates of psoriasis were 22.1 (95% CI: 21.1-23.1) and 22.7 (95% CI: 21.8-23.6) per 100 000 person-years in 2016 and 2017, respectively. The most common type of psoriasis was the late-onset type. We observed a high variation in the figures throughout the country, with a range from 0.75 (95% CI: 0.3-1.5) per 100 000 person-years in the Metropolitan region to 164.9 (95% CI: 138.6-195.1) per 100 000 person-years in the Aysen region.
We describe for the first time the incidence of psoriasis in a Latin American country. Our findings could potentially guide collaborations to improve our global understanding of psoriasis in Latin America.
银屑病是一种严重且慢性的非传染性疾病。然而，疾病发生的根本衡量标准，即发病率，在全球范围内鲜有报道。以前没有关于拉丁美洲银屑病发病率的研究。
利用行政数据库，即等待名单资料库，估计 2016 年和 2017 年智利银屑病的发病率。
我们检查了医生向皮肤科医生转诊的银屑病初诊病例，评估了诊断的一致性，并考虑到有风险的合格人口，估计了该疾病的发病率。
在大多数情况下，转诊与银屑病的新发病例相对应（73.3%；95%可信区间：66.6-79.2）。2016 年和 2017 年，银屑病的全国发病率分别为 22.1（95%可信区间：21.1-23.1）和 22.7（95%可信区间：21.8-23.6）/10 万人口年。最常见的银屑病类型为迟发型。我们观察到全国范围内的发病率差异很大，从首都地区的 0.75（95%可信区间：0.3-1.5）/10 万人口年到阿伊森地区的 164.9（95%可信区间：138.6-195.1）/10 万人口年。
我们首次描述了拉丁美洲国家银屑病的发病率。我们的发现可能有助于指导合作，以提高我们对拉丁美洲银屑病的全球认识。
