Abstract

Evaluating the extent of agreement between the EARP (Early Arthritis for Psoriatic Patients) and PEST (Psoriasis Epidemiology Screening Tool) questionnaires in screening for psoriatic arthropathy in patients with psoriasis in a tertiary-care dermatology outpatient department

Highlights

Psoriasis is a common chronic relapsing inflammatory disease with dermatological as well as systemic manifestations
The distribution of patients according to the sites affected by psoriatic lesions is depicted in Fig. 1. 40% of the patients were found to have changes in nail structure and architecture, which are associated with psoriasis
In an analysis of the Early Arthritis for Psoriasis Patients (EARP) and Psoriasis Epidemiology Screening Test (PEST) questionnaires, 43 out of the 100 enrolled patients scored positive for EARP (≥3), while 13 patients scored positive for PEST (≥3); all of these 13 patients were EARP positive as well

Summary

Introduction

Psoriasis is a common chronic relapsing inflammatory disease with dermatological as well as systemic manifestations. Evaluating the extent of agreement between the EARP (Early Arthritis for Psoriatic Patients) and PEST (Psoriasis Epidemiology Screening Tool) questionnaires in screening for psoriatic arthropathy in patients with psoriasis in a tertiarycare dermatology outpatient department. Aim: Evaluating the extent of agreement between the EARP (Early Arthritis for Psoriatic Patients) and PEST (Psoriasis Epidemiology Screening Tool) questionnaires in screening psoriatic patients for psoriatic arthropathy in a tertiary-care dermatology outpatient department (OPD). The extent of agreement between the two questionnaires was calculated by Cohen’s kappa coefficient Those positive for PsA by one or both of the questionnaires were evaluated using the CASPAR criteria. Conclusion: EARP is a better screening tool for PsA than PEST, as the latter failed to screen positively a significant number of psoriatic patients for psoriatic arthropathy. The extent of agreement between the two questionnaires can, be considered poor
