Psoriasis uncovered - measuring burden of disease impact in a survey of Australians with psoriasis

Background/Objectives Internationally, the understanding of psoriasis has advanced in recent years to the point now where it is no longer considered a benign or cosmetic skin condition but a systemic, immune-mediated disease associated with significant comorbidities and considerable detriment to quality of life. The aim of this study was to gain a better understanding of the physical, psychosocial and medical burden of psoriasis on Australian adults and the impact on health status. Methods Two large-scale multi-centre cross-sectional studies of Australian adults with psoriasis were conducted during 2010 and 2011, with the participation of a national patient representative group (Psoriasis Australia). The studies were based on detailed questionnaires that were self-completed by individuals with psoriasis. Results A total of 362 and 330 completed surveys were received in 2010 and 2011, respectively. A significant physical, psychosocial and medical burden was reported by the respondents. It was noteworthy that patients reported actively concealing their disease from the general public (83%), work colleagues (65%), friends (58%), employers (49%), family (40%), close friends (39%) and spouse/partner (20%). The mean five-dimension European quality of life (EQ-5D) score for the 2011 cohort was 0.73, representing a significant impact on their HRQoL. The presence of comorbidities, found in three-quarters of the cohort, was associated with an even greater detriment to their HRQoL (mean score 0.64). Conclusions Psoriasis imposes a significant psychosocial burden on the lives of patients, including a profound impact upon their personal and professional relationships, social interactions and quality of life, to a degree comparable to other serious chronic conditions. This study highlights the importance of collaboration between primary and specialist health-care providers in developing patient management strategies that address the spectrum of physical and psychological manifestations associated with psoriasis.
