Diagnosis of Idiopathic Pulmonary Fibrosis
Diagnosis
Table 1. Comparison of ATS/ERS/JRS/ALAT Recommendations for the Diagnosis of IPF in the 2011 and 2018 Guidelines
BAL cellular analysis
We suggest performing BAL cellular analysis. (C, )
We suggest NOT performing BAL cellular analysis. (C, )
Surgical lung biopsy
We suggest performing surgical lung biopsy. (C, )
We recommend NOT performing surgical lung biopsy. (S, )
Transbronchial lung biopsy
No recommendation for or against (, )
We recommend NOT performing transbronchial lung biopsy. (S, )
Lung cryobiopsy
No recommendation for or against (, )
We recommend NOT performing cryobiopsy. (S, )
Medical history of medication use and environmental exposures
Diagnosis of IPF requires exclusion of other known causes of ILD (e.g., domestic and occupational environmental exposures, connective tissue disease, and drug toxicity).
Serological testing to exclude connective tissue disease
Diagnosis of IPF requires exclusion of other known causes of ILD (e.g., domestic and occupational environmental exposures, connective tissue disease, and drug toxicity).
Multidisciplinary discussion
We recommend that a multidisciplinary discussion should be used in the evaluation of IPF.

PICO Questions
Should Patients with Newly Detected ILD of Unknown Cause Who Are Clinically Suspected of Having IPF Undergo a Detailed, Prompted History of Medication Use and Environmental Exposures at Home, Work, and Other Places the Patient Frequently Visits to Exclude Potential Causes of the ILD?
Should Patients with Newly Detected ILD of Unknown Cause Who Are Clinically Suspected of Having IPF Undergo Serological Testing to Exclude Exclude CTDs as Potential Causes of the ILD?
Should Patients with Newly Detected ILD of Unknown Cause Who Are Clinically Suspected of Having IPF Undergo Cellular Analysis of Their BAL Fluid?
For Patients with Newly Detected ILD of Unknown Cause Who Are Clinically Suspected of Having IPF, Should SLB Be Performed to Ascertain the Histopathology Diagnosis of UIP Pattern?
For Patients with Newly Detected ILD of Unknown Cause Who Are Clinically Suspected of Having IPF, Is TBBx a Reasonable Alternative to SLB to Ascertain the Histopathology Diagnosis of UIP Pattern?
For Patients with Newly Detected ILD of Unknown Cause Who Are Clinically Suspected of Having IPF, Is Transbronchial Lung Cryobiopsy a Reasonable Alternative to SLB to Ascertain the Histopathology Diagnosis of UIP Pattern?
Should Patients with Newly Detected ILD of Unknown Cause Who Are Clinically Suspected of Having IPF Be the Subject of MDD for Decision-making?
Should Patients with Newly Detected ILD of Unknown Cause Who Are Clinically Suspected of Having IPF Undergo Serum Biomarker (MMP-7, SPD, CCL-18, KL-6) Measurement for the Purpose of Diagnosis?
