The association between psoriasis and health-related quality of life, work productivity, and healthcare resource use in Brazil

Abstract: Background: Psoriasis is a chronic, immune mediated inflammatory condition that affects a significant amount of the global population. Yet geographic variability in the consequences of psoriasis warrants region-level analyses. Objective: The current study contributes to the psoriasis outcomes literature by offering a comprehensive assessment of the humanistic and economic burden in Brazil. Methods: The 2012 Brazil National Health and Wellness Survey (N=12,000) was used to assess health-related quality of life (Short Form-12, version 2), work productivity, and healthcare resource use associated with experiencing psoriasis vs. no psoriasis, along with varying levels of psoriasis severity. Results: A total of 210 respondents reported diagnosis of psoriasis (N=157, 42, and 11 reporting mild, moderate, and severe psoriasis, respectively). Compared with controls, respondents with psoriasis reported diminished mental component summary scores and health utilities, as well as increased presenteeism, activity impairment, and physician visits over the past six months, adjusting for covariates. Among those with psoriasis, physical health decreased as psoriasis severity increased. Although work productivity and healthcare resource utilization did not differ with psoriasis severity, the high rates of productivity loss (e.g. 45.5% presenteeism in the severe psoriasis group) suggest an economic burden. Study limitations: Cost analyses were not performed, and cross-sectional patient-reported data limit causal conclusions and may reflect reporting biases. Conclusions: Nevertheless, these results suggest a significant burden to patients with psoriasis across both humanistic and economic outcomes. The association between psoriasis and mental health aspects and health utilities were particularly strong and exceeded what would be considered clinically meaningful.
