Solution Overview

Problem

Current methods struggle to accurately predict the likelihood of patients with respiratory conditions needing additional care, such as emergency room or urgent care visits, due to challenges in assessing adherence to medication regimens.

Innovation Solution

A computer-implemented method using machine learning to generate a model based on patient adherence data, predicting risk levels for patients with respiratory conditions by training on initial datasets and applying them to additional patient data, facilitating targeted outreach to high-risk patients.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If machine learning models are used to predict patient risk, then prediction accuracy is improved, but system complexity increases

Engineering Contradiction:
Improveprediction accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

A risk prediction system serves as an intermediary between patient data and clinical decision-making. The system processes adherence data, patient attributes, and prescription information through machine learning models to generate risk scores, which then guide provider outreach efforts. This intermediary layer translates complex data patterns into actionable insights without requiring direct complex analysis by clinical staff.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

Traditional manual assessment of patient risk and adherence is replaced with automated machine learning systems. The mechanical process of clinicians manually reviewing patient records and estimating risk is substituted with computational algorithms that automatically process data and generate predictions, reducing human workload while improving consistency and accuracy.

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

2Reliability

If comprehensive patient data is collected for risk assessment, then prediction reliability is improved, but data processing requirements increase

Engineering Contradiction:
Improveprediction reliabilityVSAvoiddata processing requirements
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The system extracts only the most relevant features and variables from comprehensive patient data for modeling. Instead of processing all available data equally, the machine learning model identifies and extracts key predictors such as adherence metrics, patient attributes, and prescription patterns, discarding redundant information and reducing processing requirements while maintaining prediction reliability.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

Patient data is segmented into distinct categories including adherence data, patient attributes, and prescription information. This segmentation allows the system to process different data types through specialized processing pipelines and apply appropriate analytical methods to each segment, improving efficiency while comprehensively analyzing all relevant information.

Inventive Principle:
Principle #1Segmentation
