Abstract

Objectives: The personalised treatment demands of patients with psoriasis did not get significant attention during the pandemic lockdown. This study aimed to investigate the treatment demands of patients with psoriasis with different severities, stratified by COVID-19 pandemic conditions.

Design: Cross-sectional study design.

Setting: Multicentre study based on a national psoriasis registry in China.

Participants: A total of 22 425 adult patients with psoriasis were enrolled between August 2020 and September 2021.

Primary And Secondary Outcome Measures: The primary outcomes were patient demands for quick healing of skin lesions and improving mental health, which were collected by questionnaires. Multivariable logistic models were used to examine the impact of disease severity, as measured by Psoriasis Area and Severity Index (PASI), body surface area (BSA) and Investigator's Global Assessment (IGA), on treatment demands, as stratified by COVID-19 pandemic conditions (lockdown vs non-lockdown).

Results: Increasing PASI score significantly increased patient demands for rapid healing of skin lesions and improving mental health during non-lockdown periods. The magnitude of both associations further increased during the COVID-19 lockdown from an OR of 1.45 (95% CI 1.27 to 1.65) to 2.19 (95% CI 1.57 to 3.05) and 2.21 (95% CI 2.03 to 2.40) to 2.82 (95% CI 2.24 to 3.55), respectively. The skin lesion healing demand was more triggered by the overall irritation level (measured by IGA, OR 1.64, 95% CI 1.35 to 1.99 during non-lockdown periods vs OR 2.70, 95% CI 1.63 to 4.49 during lockdowns), while the mental health improving demand was more triggered by lesion coverage (measured by BSA, OR 2.01, 95% CI 1.85 to 2.19 vs OR 3.27, 95% CI 2.57 to 4.15).

Conclusions: Psoriasis aggravation significantly increased patients' treatment demands, especially during lockdowns. The used psoriasis severity measures highlighted patients' treatment demands differently. This suggests more accessible and personalised healthcare for patients with psoriasis should be available during future pandemics.
