Solution Overview

Problem

Current methods for determining optimal therapies in healthcare are time-consuming, expensive, and biased, with published literature expanding rapidly, making it impossible to aggregate and interpret all relevant information, leading to outdated guidelines and potential conflicts with new therapies or interactions.

Innovation Solution

A method that analyzes a knowledge graph using a patient's profile to identify relevant therapies by determining criteria and aggregate values from associated documents, generating weights and scores to determine the optimal therapy based on patient-specific attributes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual review of published literature is performed by subject-matter experts, then therapy recommendations can be provided, but the process becomes time-consuming and expensive

Engineering Contradiction:
Improvetherapy recommendation accuracyVSAvoidreview time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent introduces an automated literature analysis system as an intermediary between published literature and subject-matter experts. This system uses natural language processing and machine learning to pre-analyze, filter, and synthesize medical literature, providing structured summaries and evidence-based recommendations that experts can then validate. This intermediary processing significantly reduces the time and computational resources required while maintaining recommendation reliability.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the manual mechanical review process with an automated computational system. Instead of experts manually reading and analyzing numerous published studies, the system uses algorithms to automatically extract relevant data, compare therapies, and generate evidence-based recommendations. This substitution dramatically reduces review time and costs while scaling to handle expanding literature volumes.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If manual review of published literature is performed by subject-matter experts, then therapy recommendations can be provided, but the process becomes expensive

Engineering Contradiction:
Improvetherapy recommendation accuracyVSAvoidreview cost
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The patent implements a self-service automated analysis system that performs literature review tasks independently without requiring extensive expert intervention. The system autonomously retrieves, analyzes, and synthesizes medical literature using machine learning models, providing draft recommendations that require minimal expert validation. This self-service approach dramatically reduces the expensive human expert hours required while maintaining recommendation quality through algorithmic rigor.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces expensive manual expert review with automated computational analysis. Machine learning algorithms process and interpret medical literature at a fraction of the cost of human experts, while still extracting meaningful clinical insights. This substitution reduces operational costs while scaling to handle expanding literature volumes that would be prohibitively expensive to review manually.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Stability of the object's composition

If published literature is reviewed manually, then current guidelines can be maintained, but the guidelines become outdated as literature expands rapidly

Engineering Contradiction:
Improveguideline consistencyVSAvoidguideline currency
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The patent transforms the static, periodic guideline update process into a dynamic, continuous system. The automated analysis system continuously monitors and processes new published literature in real-time, automatically detecting when evidence supports guideline modifications. This dynamic approach ensures guidelines remain current and adaptable to new discoveries while maintaining consistency through systematic, algorithm-driven evaluation rather than ad-hoc updates.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements continuous feedback loops where the automated system constantly compares new literature against existing guidelines, identifying discrepancies and evidence-based improvements. This feedback mechanism ensures guidelines are systematically updated to reflect current evidence while maintaining internal consistency. The system provides traceable feedback on why recommendations are made, allowing for transparent and reliable guideline evolution as literature expands.

Inventive Principle:
Principle #23Feedback

4Ease of operation

If relevance is determined based on stated criteria in documents, then document selection is simplified, but the analysis lacks granularity and leads to broader generalizations

Engineering Contradiction:
Improvedocument selection simplicityVSAvoidpatient-therapy match precision
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The patent segments the document relevance assessment into multiple granular dimensions: patient demographics, disease characteristics, intervention details, outcomes, and study quality. Instead of relying on a single broad criteria match, the system analyzes each dimension separately and weights them according to patient-specific needs. This segmented approach maintains ease of operation through structured analysis while dramatically improving measurement precision by capturing nuanced patient-therapy matches that broad criteria would miss.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies local quality by tailoring the relevance analysis to each specific patient context rather than applying uniform criteria. The system adjusts the weight and importance of different document attributes based on the individual patient's characteristics, disease severity, and treatment goals. This localized approach improves precision by making each relevance assessment highly specific to the patient at hand, while the automated nature maintains operational simplicity.

Inventive Principle:
Principle #3Local quality

AI summary

Techniques for granular analysis of a knowledge graph are provided. A profile comprising a plurality of attributes is received, and a knowledge graph is analyzed to identify a plurality of therapies, based on the plurality of attributes. A document that is relevant to a first therapy of the plurality of therapies is identified, and a criterion stated in the document is determined. Further, an aggregate value is determined for the criterion, based on a plurality of participants associated with the document, wherein the first aggregate value represents attributes of the plurality of participants. A weight is generated for the document, based at least in part on the plurality of attributes and the aggregate value. A score is generated for the first therapy, based at least in part on the weight, and an optimal therapy is determined, from the plurality of therapies, based in part on the score.
