Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods fail to accurately and timely identify epilepsy patients who are candidates for surgical intervention, leading to delayed treatment and prolonged adverse effects from intractable seizures.
Innovation Solution
A computer-based clinical decision support system utilizing natural language processing and machine learning to classify epilepsy patients as having intractable or non-intractable epilepsy based on clinical text from medical records, allowing for earlier identification of candidates for surgery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If traditional clinical evaluation methods are used to identify epilepsy surgery candidates, then the identification process is simple and requires minimal technology, but the identification time is delayed by up to six years and accuracy is insufficient
Solution Approach 1:
The patent replaces traditional manual clinical evaluation methods with an automated computer-based system that uses natural language processing and machine learning algorithms to analyze clinical notes and identify surgery candidates. This substitution of mechanical/human evaluation with automated digital processing directly reduces the six-year identification delay while managing system complexity through specialized AI technologies.
Solution Approach 2:
The system performs preliminary analysis of clinical notes continuously throughout the patient's treatment course, identifying surgery candidates earlier in the disease progression rather than waiting for traditional evaluation criteria to be met. This preliminary identification action occurs years before conventional methods would flag the patient for surgery, directly addressing the time loss problem.
2Measurement precision
If natural language processing and machine learning are used to analyze clinical notes, then the identification accuracy and timing are improved, but the system complexity and computational requirements increase
Solution Approach 1:
The patent introduces natural language processing as an intermediary layer between raw clinical notes and machine learning classification. This intermediary component translates unstructured clinical text into structured data representations that the machine learning algorithms can process, enabling high-accuracy classification while isolating the complexity of different processing stages.
Solution Approach 2:
The system segments the analysis process into distinct components: natural language processing for extracting information from clinical notes, feature engineering for preparing data, and machine learning classification for determining patient category. This segmentation allows each component to be optimized independently and manages overall system complexity through modular architecture.
3Loss of time
If clinical notes are analyzed continuously throughout treatment, then earlier identification of intractable epilepsy is achieved, but the volume of data to process increases significantly
Solution Approach 1:
The natural language processing component extracts only the relevant information and features from the vast volume of clinical notes at each time point. By extracting and selecting only the necessary features for classification rather than processing all data uniformly, the system manages data volume while maintaining continuous monitoring capability throughout the treatment course.
Solution Approach 2:
The system dynamically adjusts the depth and scope of clinical note analysis based on the treatment phase and patient progress. As treatment progresses and more data becomes available, the system adapts its analysis parameters to focus on the most relevant indicators of intractability at each stage, managing data volume through adaptive processing rather than static comprehensive analysis.
