Lifetime risk, life expectancy, loss-of-life expectancy, and lifetime healthcare expenditures for psoriasis in Taiwan: a nationwide cohort followed from 2000 to 2017
Background: Patients with psoriasis have a significant disease burden throughout the life course. Nevertheless, the lifetime risk and disease burden of psoriasis across the entire lifespan is rarely quantified in an easily understandable way.

| Summary: | Background: Patients with psoriasis have a significant disease burden throughout the life course. Nevertheless, the lifetime risk and disease burden of psoriasis across the entire lifespan is rarely quantified in an easily understandable way. Objective: To estimate the cumulative incidence rate, life expectancy, loss-of-life expectancy, and lifetime healthcare expenditures for incident psoriasis. Design and methods: Using real-world nationwide data from the National Health Insurance Research Database of Taiwan for 2000-2017, along with the life tables of vital statistics, we estimated cumulative incidence rate, life expectancy, loss-of-life expectancy, and lifetime healthcare expenditures for those with psoriasis using a semi-parametric survival extrapolation method. Results: A total of 217,924 new psoriasis cases were identified. The lifetime risk of psoriasis in patients aged 18-80 for both sexes decreased in Taiwan with a cumulative incidence rate of 7.93% in 2000 to 3.25% in 2017. The mean (±standard error) life expectancy after diagnosis was 27.11 (± 1.15) and 27.14 (±1.17) years for patients with moderate-to-severe psoriasis and psoriatic arthritis, respectively. Patients with moderate-to-severe psoriasis and psoriatic arthritis had a mean (±standard error) loss-of-life expectancy of 6.41 (±1.16) and 6.48 (±1.17) due to psoriasis, respectively. Male patients have higher lifetime and annual lifetime healthcare expenditures than female. Mean life expectancy, loss-of-life expectancy, and lifetime cost were relatively higher for younger patients. Conclusion: Among psoriatic patients, patients with moderate-to-severe psoriasis and psoriatic arthritis had substantial years of life lost, particularly for younger patients. Our results provide a reliable estimation of lifetime disease burden, and these estimates will help health authorities in cost-effectiveness assessments of public health interventions and allocation of services resources to minimize loss-of-life expectancy, and lifetime healthcare expenditures in patients with psoriasis. |
