Radiologic Technologists' Perceptions of Imaging Appropriateness in Radiography, CT, and Mammography

Area of Science:

• Radiology
• Medical Imaging
• Healthcare Policy

Background:

• Appropriate imaging is crucial for patient care and resource management.
• Understanding perceptions of imaging appropriateness among healthcare professionals is essential for improving utilization.

Purpose of the Study:

• To assess U.S. radiologic technologists' views on imaging appropriateness across different modalities.
• To explore how descriptive variables correlate with perceptions of imaging appropriateness.

Main Methods:

• A cross-sectional survey was administered to radiologic technologists in radiography, computed tomography, and mammography.
• Survey instrument validity and reliability were assessed, followed by statistical analysis including one-way ANOVA.

Main Results:

• Technologists estimated 16%-30% of examinations were inappropriate, primarily due to fear of lawsuits and patient expectations.
• Key factors influencing appropriateness perceptions included imaging modality, shift length, work shift, practice facility, patient population, and education level.
• No significant differences were found based on employment status, role, age, experience, credentials, gender, or location.

Conclusions:

• Imaging appropriateness is complex, influenced by factors beyond clinical necessity.
• Increased technologist familiarity with appropriate use criteria and implementation of clinical decision support are recommended.
• Minimizing radiation exposure risk should remain central to imaging decisions.
