Patient Health State Compound Score Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current patient monitoring methods provide a narrow time snapshot of a patient's health state and do not effectively leverage continuous health state information from bedside electronic devices, leading to inefficient use of caregivers' time and incomplete assessment of patient condition.
Innovation Solution
Generating compound score distributions from multiple sets of vital sign measurements using histograms and predetermined bins, allowing for a more comprehensive evaluation of a patient's health state through the determination of a representative singular compound score.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If manual acquisition of vital signs is performed by caregivers going room to room, then health state parameters can be obtained, but caregivers' time is consumed that could otherwise be used for patient care
Solution Approach 1:
The system enables self-service by having bedside electronic devices automatically measure and transmit health state parameters without requiring caregiver intervention. The automated acquisition system collects vital signs continuously and makes them available for analysis, eliminating the manual time-consuming process while ensuring comprehensive health information is captured.
Solution Approach 2:
The patent replaces the mechanical manual process of caregivers physically going to patients with an automated electronic system. Bedside devices automatically detect and transmit health state parameters through electronic communication, substituting the manual mechanical approach with an automated electronic measurement and transmission system.
2Ease of operation
If singular observations of vital signs are used to create early warning scores, then a simple assessment can be made, but only a narrow time snapshot of the patient's health state is provided
Solution Approach 1:
The system merges multiple individual score distributions from different vital sign parameters into a compound score distribution. By combining the information from respiratory rate, heart rate, blood pressure, temperature, and other parameters into a unified compound score, the system maintains assessment simplicity while incorporating comprehensive continuous health state information from all monitored parameters.
Solution Approach 2:
The patent transitions from single-point observations to continuous monitoring by adding the time dimension. Instead of taking a single snapshot, the system continuously collects vital sign data over time, creating score distributions that reflect the temporal evolution of health state, thereby providing both simplicity and continuity.
3Loss of information
If bedside electronic devices continuously measure health state parameters, then comprehensive health information is obtained, but the information is not effectively leveraged for patient assessment
Solution Approach 1:
The system implements feedback by continuously monitoring health state parameters and dynamically updating the compound score distribution. The compound score provides real-time feedback on patient status, enabling caregivers to quickly assess deterioration risks and respond appropriately, thereby effectively leveraging continuous information for efficient patient assessment and care decision-making.

AI summary
A method includes generating at least first and second histograms respectively for at least first and second sets of vital sign measurements using at least first and second predetermined bins. The first and second sets of the vital sign measurements each include at least two measurements acquired at different times, and the first and second vital sign are different vital signs. The method further includes generating a first score distribution for the first vital sign by mapping each bin of the first predetermined bins to a corresponding predetermined score. The method further includes generating a second score distribution for the second vital sign by mapping each bin of the second predetermined bins to a corresponding predetermined score. The method further includes generating a compound score distribution for the first and second vital signs based on the first and second score distributions, the compound score distribution indicates a patient's health state.
