Summary
Radiology resident interpretation time for screening mammograms significantly decreases with more breast imaging rotations and higher postgraduate year levels. Experience, not imaging technology like digital breast tomosynthesis (DBT) or full-field digital mammography (FFDM), improves efficiency.
Area of Science:
- Radiology
- Medical Education
- Health Services Research
Background:
- Screening mammogram interpretation efficiency is crucial for timely patient care.
- Factors influencing interpretation time among radiology residents require investigation.
Purpose of the Study:
- To evaluate factors impacting screening mammogram interpretation time in radiology residents.
- To compare interpretation times based on rotation number and postgraduate year (PGY).
Main Methods:
- Prospective study with radiology residents performing simulated screening mammogram interpretations.
- Utilized eye-tracking technology for detailed analysis of visual inspection and reporting times.
- Compared interpretation times across different breast imaging rotation levels and PGY levels.
Main Results:
- Overall interpretation time per case decreased significantly with increased rotations (first vs. third) and PGY level (PGY2 vs. PGY5).
- Visual inspection time also showed significant decreases with experience.
- No significant difference in interpretation time was found between digital breast tomosynthesis (DBT) and full-field digital mammography (FFDM).
Conclusions:
- Radiology resident interpretation efficiency for screening mammograms improves with experience.
- Increased postgraduate year level and number of breast imaging rotations correlate with reduced interpretation times.
- Mammography technology type (DBT vs. FFDM) did not significantly impact interpretation efficiency in this study.
