Abstract
BackgroundResidents usually cover night and weekend shifts issuing the preliminary reading of radiological studies in university hospitals. This is essential to strengthening decision-making skills when facing complex cases independently. However, there should be a balance between patient safety and academic experience since some concern has been expressed about the accuracy of the interpretations generated by trainees. This work aims to evaluate and characterize the discrepancies in preliminary reports issued by radiology residents. Material and methodsRadiologists filled out a questionnaire to evaluate preliminary reports of trainees considering diagnosis, findings description, clinical approach changes, and critical findings. Analysis was performed considering modality, imaging type, body part, and resident academic year. A Chi-square test with a significance level α of 0.05 was used to make group comparisons. ResultsA total of 9072 studies were reviewed. Major and minor overall discrepancy rates were 1.7% and 8.3%, respectively. Minor discrepancy rate, findings description, and critical findings identification improved with increasing academic year, both overall and by modality. Discrepancy rates were lower for CT than MR and neuroimaging than for body-imaging studies. The highest major and minor discrepancy rates as abdomen/pelvis CT and lumbar-spine MR, respectively. Two percent of reports presented discrepancies that could generate a medical approach change. ConclusionDiscrepancy rates are low and comparable with those reported in the literature. These rates tend to improve as the resident's academic year increases. Our results suggest that radiology residents' coverage of night shifts and weekends is a practice that benefits the educational process without negatively impacting patient safety.
