Solution Overview

Problem

The management of polytrauma patients in trauma centers is challenging due to the complexity of their condition, which involves multiple organ systems and fluctuating levels of consciousness, requiring quick clinical decision-making and life-saving interventions within a critical 72-hour window, where existing risk scoring methods are cumbersome, static, and rely heavily on instinct and clinical experience.

Innovation Solution

A clinical insight and decision support tool is developed, implemented on a cloud-based data analytic platform, using a predictive model to compute a composite mortality risk score from real-time and historical patient data, including EHR and non-EHR information, with machine learning to refine accuracy and present actionable insights to care teams, reducing cognitive overload and bias.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing risk scoring methods are used, then clinical decision-making can be supported, but the methods are cumbersome and static, requiring heavy reliance on instinct and clinical experience

Engineering Contradiction:
Improvedecision-making accuracyVSAvoidscoring method complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent transforms static risk scoring methods into dynamic, real-time computational models that continuously update mortality risk scores as new patient data becomes available. The system processes incoming EHR data streams and recalculates risk scores dynamically, allowing the scoring mechanism to adapt to changing patient conditions automatically rather than relying on static calculations and clinician intuition.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent replaces manual, instinct-based clinical judgment with an automated computational system that uses machine learning algorithms and predictive models. The mechanical process of clinicians manually assessing patient condition and applying scoring criteria is substituted with an automated information processing system that computes risk scores objectively and consistently, reducing reliance on human instinct and experience variability.

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

2Measurement precision

If comprehensive patient data is analyzed, then decision-making accuracy improves, but cognitive overload increases for care teams

Engineering Contradiction:
Improverisk assessment accuracyVSAvoidcare team workflow simplicity
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The patent extracts and isolates the most critical risk factors and data elements from the comprehensive patient dataset, presenting only the most relevant information to care teams. The system identifies and extracts key predictors of mortality risk, displaying them in a prioritized format that highlights what matters most for decision-making, rather than presenting the entire raw dataset which would cause cognitive overload.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces an intermediary computational layer between the comprehensive patient data and the care team. This intermediary system processes, analyzes, and translates raw data into meaningful risk scores and actionable insights, acting as a mediator that bridges the gap between data complexity and clinical usability. The care team interacts with the simplified output rather than directly with the complex underlying data.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Speed

If real-time data processing is implemented, then timely interventions are enabled, but system complexity and computational requirements increase

Engineering Contradiction:
Improveresponse timeVSAvoidsystem architecture complexity
Core Design Contradiction:
SpeedVSDevice complexity

Solution Approach 1:

The patent implements preliminary action by pre-processing and structuring patient data as it enters the system, organizing information into standardized formats and identifying key data elements in advance. The system performs preliminary data validation, normalization, and feature extraction, so that when real-time risk calculation is needed, the computational workload is already reduced and the data is ready for rapid processing, enabling timely interventions without requiring overly complex real-time computation infrastructure.

Inventive Principle:
Principle #10Preliminary action

AI summary

A clinical insight and decision support visualization tool includes a data ingestion logic module that automatically accesses, in real-time, electronic health data of a plurality of trauma patients being treated by a care team at a healthcare institution. The tool further includes a data analysis module that automatically applies at least one predictive model to analyze the processed patient data and determine a current mortality risk score value for each patient, and a user interface module that presents real-time and historical information for each trauma patient including a current mortality risk score value, a categorization of the current mortality risk score value, top contributors to the current mortality risk score value and their respective values, and a trend plot of historic mortality risk score values.
