ACR Appropriateness Criteria® Diffuse Lung Disease

Area of Science:

• Pulmonology
• Radiology
• Medical Imaging

Background:

• Diffuse lung diseases (DLDs), also known as interstitial lung diseases, comprise a wide spectrum of parenchymal lung disorders.
• Hundreds of etiologies exist, necessitating accurate diagnostic and management strategies.
• Imaging is crucial for DLD diagnosis and monitoring, often complemented by multidisciplinary discussions.

Framework:

• The guidelines address three key clinical scenarios: initial suspected DLD, acute exacerbations in confirmed DLD, and routine follow-up of stable DLD.
• These evidence-based recommendations are derived from the American College of Radiology Appropriateness Criteria.
• Methodologies like RAND/UCLA and GRADE inform the appropriateness ratings for imaging procedures.

Implementation:

• The guidelines aim to standardize the evaluation of diffuse lung diseases through imaging.
• They provide a framework for selecting the most appropriate imaging studies based on clinical presentation.
• Expert opinion may be used to supplement evidence in cases with limited data.

Implications:

• Standardized imaging guidelines can improve diagnostic accuracy and patient management for diffuse lung diseases.
• Appropriate use of imaging may lead to more efficient healthcare resource utilization.
• These guidelines support clinicians in navigating the complex landscape of interstitial lung disease diagnosis and follow-up.
