VTE Decision Support Tool Using Complement Protein Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies for detecting and treating venous thromboembolism (VTE) are inadequate, as they are often invasive, expensive, and ineffective in identifying leading indicators for prevention, leading to delayed diagnosis and ineffective treatment, especially in postmenopausal women.
Innovation Solution
A decision support tool utilizing a machine-learning model that analyzes the quasi-Dirichlet distribution relationship between total hemolytic complement (CH50) activity and complement protein C3 levels to predict and diagnose VTE, providing predictive, diagnostic, and prognostic applications, and guiding prevention and treatment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional anticoagulant treatments are used for VTE prevention in postmenopausal women, then treatment coverage is provided, but effectiveness is limited and cost-efficiency is poor
Solution Approach 1:
The decision support tool performs preliminary identification of postmenopausal women at high risk for VTE by analyzing complement protein levels (C3, C4, CH50) before VTE events occur. This enables early intervention with appropriate treatments, improving prevention effectiveness while avoiding unnecessary treatment of low-risk patients, thereby enhancing cost-efficiency.
Solution Approach 2:
The system changes the diagnostic parameters from traditional clinical risk factors to specific complement protein levels (C3, C4, CH50) and their mathematical transformations. This parameter change enables more accurate identification of high-risk patients, improving the reliability of VTE prevention while optimizing treatment allocation for better cost-efficiency.
2Reliability
If expensive treatments like eculizumab are used for all postmenopausal women, then comprehensive coverage is provided, but cost becomes prohibitively high
Solution Approach 1:
The decision support tool applies local quality by identifying specific subgroups of postmenopausal women with elevated complement protein levels who would benefit most from expensive treatments like eculizumab. Instead of uniform treatment coverage, the system tailors treatment recommendations to individual risk profiles, ensuring effective use of expensive medications only where needed, thereby reducing overall treatment costs while maintaining high effectiveness.
3Loss of time
If conventional VTE detection methods are used, then standard care is provided, but early detection of leading indicators is delayed
Solution Approach 1:
The system replaces conventional mechanical/direct observation detection methods with a computational decision support tool that analyzes complement protein levels and their mathematical relationships. This substitution enables early detection of leading indicators for VTE by identifying subtle patterns in complement protein data, improving both detection timing and risk identification accuracy simultaneously.

AI summary
An improved decision support tool is provided for detecting and treating human patients at risk for having (or developing) venous thromboembolism VTE. The tool determines a quantitative probability of VTE by utilizing a smart sensor based on a particular machine-learning model for detecting specific biomarkers determined to be related to VTE. In particular, a quantitative probability of VTE may be determined via a model based on interrelationships between multiple components of the human body's complement cascade and their coupling to coagulation processes. In one aspect, a quasi-Dirichlet distribution “mixture” relationship between total hemolytic complement (CH50) activity and complement protein C3 levels is employed as part of a smart sensor and decision support tool to provide predictive, diagnostic, and prognostic applications and for guiding prevention and treatment of acute VTE. Where the smart sensor determines a risk for VTE, then the decision support tool may initiate an intervening action.
