should not be used in the majority
of patients with IPF but may be a
reasonable choice in a minority
Clinicians
Most patients should receive the recommended
course of action
Be more prepared to help patients to make a decision that is
consistent with the patient’s own values
Policy Makers
The recommendation can be adopted as a policy in
most situations
There is a need for substantial debate and involvement of
stakeholders
IPF = idiopathic pulmonary fibrosis.
DEFINITION AND EPIDEMIOLOGY
DEFINITION
■ Idiopathic pulmonary fibrosis (IPF) is a specific form of chronic, progressive fibrosing
interstitial pneumonia of unknown cause, occurring primarily in older adults, limited to
the lungs, and associated with the histopathologic and/or radiologic pattern of usual
interstitial pneumonia (UIP) defined in Table 4.1
■ The definition of IPF requires the exclusion of other forms of interstitial pneumonia
including other idiopathic interstitial pneumonias (IIP) and interstitial lung disease (ILD)
associated with environmental exposure, medication, or systemic disease.
CLINICAL PRESENTATION
■ IPF should be considered in all adult patients with unexplained chronic exertional dyspnea,
and commonly presents with cough, bibasilar inspiratory crackles, and finger clubbing.1
The optimal HRCT technique for evaluation of ILD is provided in Table 5.
■ The incidence of IPF increases with older age, with presentation typically occurring in the
sixth and seventh decades.1
■ IPF is rare in patients younger than 50 years of age.1
■ IPF is more common among men than among women.1
■ The majority of patients with IPF have a history of cigarette smoking.1
