Laterality errors in radiology reports are rare and did not cause wrong-sided surgeries. Voice recognition software did not impact error rates but significantly reduced correction times for laterality errors.
Area of Science:
- Radiology and Medical Imaging
- Health Informatics
- Patient Safety
Background:
- Laterality errors in medical reports can potentially impact patient management and outcomes.
- Voice recognition software is increasingly used in medical documentation, necessitating an evaluation of its effect on error rates.
Purpose of the Study:
- To determine the incidence, types, and clinical implications of laterality errors in radiology reports.
- To assess the impact of voice recognition software on the frequency of laterality errors.
Main Methods:
- Retrospective analysis of 2,923,094 radiology reports (2007-2011).
- Categorization of laterality errors by modality, body part, discrepancy type (major/minor), and clinical significance.
- Comparison of laterality error rates in reports generated with and without voice recognition software.
Main Results:
- A total of 0.055% of reports contained corrected laterality errors, with 0.0019% being major.
- Voice recognition-generated reports showed no significant difference in major laterality error rates (0.00188% vs. 0.00192%).
- No wrong-sided surgeries occurred; however, 3 patients experienced potential adverse effects from major discrepancies.
Conclusions:
- Laterality error rates are low and did not lead to wrong-sided surgeries in this study population.
- Voice recognition software did not influence the rate of laterality errors causing major discrepancies.
- Voice recognition significantly decreased the time to correct laterality errors.
