title: Respiratory disability and impairment: what is new?
abstract: OBJECTIVE
  This review summarizes recent advances concerning respiratory impairment and disability.
  
  
  RESULTS
  The traditional impairment assessment approach, depending heavily on clinical pulmonary function testing to estimate the match between the patient's sustainable oxygen consumption and the workplace requirements, continues to be widely used. Recent work indicates the need to reassess underlying concepts for several reasons: The relationship between basic pulmonary function tests and sustainable oxygen consumption varies among patients and conditions. Studies of the respiratory demands of modern workplaces need to be updated. The concepts are less easily applied to asthma than other disorders. Research studies present differing definitions of 'disability', and therefore the methods of relating impairment (function loss) and disability require reassessment. Recent advances provide improved understanding of the large societal and personal impacts of respiratory impairment and disability.
  
  
  CONCLUSIONS
  Clinicians, policymakers, and researchers should carefully consider how well the current highly specified impairment rating systems can be improved for accuracy and relevance to current home and work activities. In addition to measuring 'impairment', clinicians should consider factors affecting how impairments lead to disability.
