International Perspectives on Radiology in Preventive Screening

Area of Science:

• Radiology
• Health Economics
• International Health Policy

Background:

• The International Economics Committee of the American College of Radiology (ACR) initiated a comparative study of radiology practices globally.
• This article is the second in a series, focusing on international differences in imaging modality use for disease screening.

Purpose of the Study:

• To compare the utilization of imaging modalities within screening algorithms for common diseases across various countries.
• To provide radiologists with a detailed understanding of health system practice variations among selected nations.

Main Methods:

• A standardized survey was administered to committee members from 10 countries (developed and developing).
• Data collection focused on the use of imaging in screening protocols for diseases like breast cancer, lung cancer, and abdominal aortic aneurysm.

Main Results:

• Striking differences and similarities were observed in radiology screening practices, even among Organisation for Economic Co-operation and Development (OECD) member nations.
• Breast cancer screening (mammography) showed similar techniques and high insurance coverage, but differing recommended screening ages.
• Lung cancer and abdominal aortic aneurysm screening exhibited variable participation and lower insurance coverage across surveyed countries.

Conclusions:

• Survey data from practitioners offers valuable insights into the role of radiology in screening programs.
• Comparative differences in screening programs, particularly the use of imaging, may influence future healthcare cost containment policies globally.
• Understanding these international variations is crucial for informing health policy decisions in the United States and abroad.
