title: Work-related lost productivity and its economic impact on Canadian patients with moderate to severe psoriasis.
abstract: BACKGROUND
  Psoriasis impacts many different areas of a patient's life, including work productivity. There is no information regarding lost productivity owing to psoriasis in a Canadian population.
  
  
  OBJECTIVE
  The objective of this study was to determine the lost productivity of Canadian patients with moderate to severe psoriasis.
  
  
  METHODS
  Seventy-nine consecutive Canadian dermatology patients were interviewed and completed the Work Productivity and Activity Impairment Questionnaire (WPAIQ).
  
  
  RESULTS
  On average, 2.2 hours (+/- 5.6 hours) were lost from work per week owing to psoriasis-related events. Absence from work may result in lost mean patient wages of C$2,270.84 per person per year. Total lost wages owing to moderate to severe psoriasis may cost up to approximately $749 million for all moderate to severe psoriasis patients in Canada.
  
  
  CONCLUSIONS
  The results from our study indicate that moderate to severe psoriasis may have a substantial impact on the work productivity of patients with this disease.
