title: Disease severity and quality of life in a follow-up study of patients with occupational contact dermatitis.
abstract: BACKGROUND
  Few studies have investigated how occupational contact dermatitis and its severity affect patients' quality of life (QoL).
  
  
  OBJECTIVE
  To investigate the impact of occupational contact dermatitis and its severity on patients' QoL, and to examine the association between different QoL measures.
  
  
  METHODS
  Patients previously diagnosed with occupational contact dermatitis completed the Short Form Health Survey (SF-36) and Dermatology Life Quality Index (DLQI). Disease severity was rated both by the patient and by the physician.
  
  
  RESULTS
  Of a possible 725, a total of 119 patients (16.4%) were included in the study, and, at follow-up, just over 21% had normal skin and 18.3% had progressed to persistent dermatitis. The SF-36 median physical component summary score was 52 [interquartile range (IQR): 43-56] and the mental component summary median score was 51 (IQR: 44-57). The correlation between patient-rated and physician-rated disease severity was moderate (r = 0.708, p < 0.00001). The correlation between the disease severity measures and DLQI was moderate, whereas the SF-36 correlated poorly with both the DLQI and disease severity measures.
  
  
  CONCLUSIONS
  QoL was generally reduced in this group of patients with occupational contact dermatitis, with some correlation between severity and DLQI. The DLQI was a more sensitive measurement of QoL than the SF-36 in this patient population. Incorporating disease severity rating with a QoL questionnaire is valuable in occupational contact dermatitis and is recommended.
