Occupational Interstitial Lung Diseases.

Objective: Evidence-based diagnostic and treatment guidelines for occupationally related interstitial lung diseases (ILDs) have been developed and are summarized herein.
Methods: Comprehensive literature reviews were conducted with article abstraction, critiquing, objective grading, and evidence table compilation. A multidisciplinary expert panel drafted evidence- and consensus-based guidance. External peer-review was incorporated.
Results: Recommendations for diagnosis (n = 12) and management (n = 4) of ILD were developed. Spirometric testing, chest radiographs, and high-resolution computerized tomographic scans were recommended based upon evidence. In addition to a detailed clinical history, carbon monoxide diffusion capacity, sputum sampling, exposure assessment, 6-minute walk test, and bronchoalveolar lavage were also recommended. There was no recommendation regarding chest magnetic resonance imaging due to lack of evidence.
Conclusions: Recommendations for diagnosis and management of ILD are supported by quality evidence. These guidelines may be useful to help guide providers who are tasked with diagnosing and/or treating patients with occupationally related ILD.
