Clinical Decision Support Visualization for Trauma Mortality Risk
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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.
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.
2Measurement precision
If comprehensive patient data is analyzed, then decision-making accuracy improves, but cognitive overload increases for care teams
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.
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.
3Speed
If real-time data processing is implemented, then timely interventions are enabled, but system complexity and computational requirements increase
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.
Data Source
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.
