Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The clinical data integration process is time-consuming and error-prone due to the need for manual development of complex mapping logic to convert data from disparate clinical information systems into a single canonical format, requiring technical expertise and frequent validation.
Innovation Solution
A machine learning approach that uses anomaly detection models to automatically identify data discrepancies by training on historical data and applying these models to new data sets, generating alerts and reports for integration errors, and continuously updating based on feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual mapping rules are constructed to handle data formatting discrepancies, then data integration accuracy is improved, but development time and complexity increase significantly
Solution Approach 1:
The system enables self-service by automatically generating mapping rules through machine learning models that learn from historical data. The anomaly detection component autonomously identifies discrepancies and suggests corrections without requiring manual intervention from integration engineers, thereby maintaining high accuracy while significantly reducing development time.
Solution Approach 2:
The patent replaces the mechanical process of manual rule construction with an automated machine learning system. The ML component trains anomaly detection models that automatically analyze data patterns and generate mapping rules, substituting human expert manual work with an automated intelligent system that achieves comparable or superior accuracy more efficiently.
2Adaptability or versatility
If manual mapping rules are constructed for each integration project, then adaptability to specific clinical information systems is improved, but device complexity and maintenance burden increase
Solution Approach 1:
The machine learning component provides a universal solution that can handle multiple different clinical information systems and data formats through a single automated system. The anomaly detection models learn from diverse historical data and can generalize to handle various native formats (HL7, proprietary formats, etc.) without requiring separate manual rule sets for each system, thereby reducing overall complexity while maintaining adaptability.
Solution Approach 2:
The system adapts to different clinical information systems by dynamically changing the parameters and characteristics of the anomaly detection models based on the specific data being processed. Rather than creating complex static mapping rules for each system, the ML component adjusts its detection thresholds, feature weights, and model parameters automatically based on the characteristics of the source and target systems involved.
3Reliability
If mapping rules are manually validated and updated frequently, then data integration reliability is improved, but loss of time and operational effort increase
Solution Approach 1:
The system implements continuous feedback through the anomaly detection component that monitors data integration processes in real-time. When discrepancies are detected, the system automatically feeds this information back to update the mapping rules and retrain the anomaly detection models, creating a self-improving system that maintains high reliability without requiring frequent manual validation cycles.
Solution Approach 2:
The anomaly detection component operates continuously to monitor and validate data integration processes, rather than requiring periodic manual intervention. The system performs ongoing anomaly detection, automatically updates mapping rules when issues are identified, and continuously retrains models, maintaining reliable data integration through continuous automated action rather than discontinuous manual validation.
Data Source
AI summary
Techniques are described that employ a machine learning approach for detecting data discrepancies during clinical data integration. In an embodiment, a computer implemented method comprises receiving historical clinical data messages converted from a native format to a target format via a mapping function that maps different sets of historical data elements included in the historical clinical data messages into defined data description paths, and training anomaly detection models for each of the defined data description paths to characterize normal characteristics of the different sets of historical data elements for each of the defined data description path. The method further comprises receiving new clinical data messages converted from the native format or to the target format via the mapping function, and detecting abnormal characteristics of different sets of new data elements for corresponding data description paths of the defined data description paths using the anomaly detection models.
