title: Identification of psoriatic patients at risk of high quality of life impairment.
abstract: Psoriasis is a systematic chronic disease with large influence on patients' quality of life (QoL). The aim of this study was to assess the QoL of patients with psoriasis using generic, dermatology-specific and psoriasis-specific instruments simultaneously, to investigate the relationships between dimensions or subscales of the questionnaires and to identify categories of patients at risk of a high QoL impairment. The study comprised 100 consecutive patients with psoriasis treated at the Department of Dermatology, Clinical Center "Zvezdara", Belgrade, from January to December 2011. Three QoL questionnaires were administered: the EuroQol-5D (EQ-5D), the Dermatological Life Quality Index (DLQI) and the Psoriasis Disability Index (PDI). The Psoriasis Area and Severity Index was used in evaluating disease severity. According to our results the QoL of psoriatic patients was impaired (the overall DLQI and PDI scores were 10.5 ± 7.2 and 13.4 ± 8.7, respectively, while EQ visual analog scale score was 48.8 ± 25.1). The most predictive factor of QoL impairment was disease severity, followed by sole and nail involvement. Psoriatic arthritis and bleeding were also associated with impaired QoL. Significant correlations between the instruments used in this study were in the expected directions. Mainly strong and moderate significant correlations ranging 0.26-0.84 were seen between DLQI and PDI instruments. A detailed approach to QoL assessment may give to the dermatologist useful information that could be of help in identifying patients belonging to categories at risk of high QoL impairment due to psoriasis, thus guiding them in clinical practice.
