Radiology residents exhibit high accuracy on overnight call, with discrepancy rates varying by imaging modality and resident experience. Senior residents show lower error rates than junior residents.
Area of Science:
- Radiology
- Medical Education
- Quality Improvement
Background:
- Radiology residents gain independence through overnight call.
- Analyzing resident report discrepancies is crucial for patient care.
- Previous data on on-call resident error rates is fragmented.
Purpose of the Study:
- To consolidate data on radiology resident preliminary report discrepancy rates.
- To compare these rates across different imaging modalities.
- To evaluate discrepancy rates based on resident training year.
Main Methods:
- A systematic PubMed search was conducted in August 2024.
- Inclusion criteria were applied to select relevant studies.
- Statistical analysis was performed on pooled data from 20 studies (616,918 reports).
Main Results:
- Pooled major discrepancy rates: radiographs (0.64%), US (0.38%), CT (1.35%), MRI (1.86%).
- Discrepancy rates decreased with resident seniority: R1 (1.27%) to R4 (0.67%).
- Highest rate observed in first-year residents (R1) reading MRI (8.70%).
Conclusions:
- Radiology residents demonstrate high accuracy during independent call.
- Real-time supervision may expedite final reports; implementation is institution-specific.
- Standardization of discrepancy classification is recommended for future research.
