Problem
Medical professionals face challenges in accurately documenting patient information due to the potential for human errors such as laterality errors, gender errors, and critical findings being overlooked or buried deep within reports, leading to inefficiencies and safety issues in healthcare delivery.
Innovation Solution
A system utilizing natural language understanding (NLU) techniques to analyze medical reports for errors and critical results, providing alerts to professionals in real-time, and allowing for the correction of errors before report finalization, while minimizing false positives through contextual information analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual review of medical reports is performed by medical professionals, then accuracy in identifying errors and critical findings can be maintained, but time consumption and workload increase significantly
Solution Approach 1:
The patent introduces an intermediary system comprising natural language processing algorithms and machine learning models that act as a mediator between the medical report and the reviewing professional. This automated analysis system pre-processes reports to identify potential errors, laterality issues, and critical findings, presenting only relevant cases to medical professionals for verification. This intermediary layer maintains high accuracy while significantly reducing the time and workload required for manual review.
Solution Approach 2:
The system performs preliminary automated analysis of medical reports before they reach medical professionals for final review. By pre-identifying potential errors, critical findings, and anomalies through algorithmic analysis, the system prepares reports in advance with highlighted areas requiring attention. This preliminary action filters out routine cases and presents only ambiguous or critical cases to professionals, reducing their workload while maintaining accuracy.
2Productivity
If automated systems are used to analyze medical reports, then time efficiency and productivity improve, but risk of false positives and reduced accuracy increases
Solution Approach 1:
The patent implements a feedback mechanism where the automated system's initial analysis results are presented to medical professionals who verify and correct the findings. Their corrections and validations feed back into the system to refine and improve the algorithms over time. This closed-loop feedback system allows the automated tool to maintain high productivity while continuously improving accuracy and reducing false positives through learning from professional expertise.
Solution Approach 2:
The system merges automated algorithmic analysis with human expert review in a hybrid approach. The automated component handles routine pattern recognition and initial filtering at high speed, while human experts provide contextual understanding and final validation. This combination leverages the speed and consistency of machines with the judgment and adaptability of human professionals, achieving both high productivity and reliable accuracy.
3Measurement precision
If comprehensive analysis of all medical reports is performed, then detection of errors and critical findings is maximized, but system complexity and computational resources increase
Solution Approach 1:
The patent applies local quality by focusing computational resources on specific high-risk areas within medical reports rather than uniformly analyzing all content. The system identifies and prioritizes analysis of sections most likely to contain errors or critical findings, such as laterality descriptors, critical result sections, and abnormal findings. This targeted approach maximizes detection capability while reducing overall system complexity and resource requirements by applying intensive analysis only where needed.
Solution Approach 2:
The system segments the medical report analysis into distinct modular components, each handling specific types of information (e.g., patient demographics, clinical findings, imaging results, laboratory values). This segmentation allows the complex analysis task to be divided into manageable modules that can be processed independently and in parallel, reducing overall system complexity while maintaining comprehensive detection capabilities across all report sections.
4Object-affected harmful factors
If frequent alerts are generated to notify professionals of potential errors, then patient safety is enhanced, but user experience deteriorates due to alert fatigue
Solution Approach 1:
The system applies partial action by generating alerts selectively rather than for every potential issue. It prioritizes and alerts only on high-confidence findings, critical results, and high-risk errors based on risk stratification and confidence scoring. By being selective about which issues trigger alerts, the system maintains patient safety through comprehensive monitoring while avoiding alert fatigue by not notifying users about every minor or low-confidence finding.
Solution Approach 2:
The alert system applies different notification strategies based on the severity and type of finding. Critical findings generate immediate high-priority alerts, while less urgent issues are flagged for routine review or grouped with other findings. This differentiated approach ensures that important safety issues are promptly communicated while reducing the volume of routine notifications, thereby maintaining patient safety without overwhelming users with excessive alerts.

AI summary
Systems and methods for analyzing a medical report to determine whether the medical report includes at least one instance of at least one category selected from a group consisting of: gender error, laterality error, and critical finding. In some embodiments, one or more portions of text are identified from the medical report. Contextual information associated with the medical report is used to determine whether the identified one or more portions of text comprise at least one instance of at least one category selected from the group.
