  Study Question: How profoundly are adults with 
  undiagnosed respiratory symptoms 
  affected by 
  dyspnea? 
  Results: In community-based adults with undiag- 
  nosed respiratory symptoms, those identiﬁed with 
  preserved ratio impaired spirometry experienced the 
  greatest impact of dyspnea, followed by those with 
  undiagnosed asthma or COPD. Greater dyspnea 
  impact was associated with increased health care 
  utilization, lower quality of life, and reduced work 
  productivity. 
  Interpretation: Dyspnea imposes burdens on the 
  health care system and is associated with impaired 
  quality of life and work productivity.
