Solution Overview

Problem

Current methods lack effective assessment criteria for the work performance of medical rescue-related organizations, particularly in scenarios like out-of-hospital cardiac arrest, where bystander intervention is critical but often lacking, leading to low survival rates.

Innovation Solution

A method and apparatus for assessing work performance by acquiring witness information data pairs, calculating rescue action conversion efficiency, and evaluating the performance of organizations based on witness rates and action rates to determine the proportion of patients receiving effective rescue measures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If standardized Utstein reporting template is used to record rescue process, then rescue process documentation is improved, but ability to assess organizational work performance deteriorates

Engineering Contradiction:
Improverescue process documentationVSAvoidorganizational work performance assessment
Core Design Contradiction:
Loss of informationVSMeasurement precision

Solution Approach 1:

The patent segments the assessment into multiple dimensions: witness rate (w1), witness action rate (t1), and rescue action conversion efficiency (T). Each dimension captures a specific aspect of organizational performance, transforming the undifferentiated rescue process data into structured, assessable metrics that can be independently measured and improved.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces rescue action conversion efficiency as an intermediary metric that connects witness observation to actual rescue outcomes. This intermediary measure (T = w1 × t1 × k1) bridges the gap between passive documentation and active performance assessment, enabling organizations to evaluate their effectiveness in converting witnessed events into successful rescues.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If focus is placed on patient-centered rescue process, then patient treatment quality is improved, but assessment of bystander and organizational performance deteriorates

Engineering Contradiction:
Improvepatient treatment qualityVSAvoidbystander and organizational assessment
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent inverts the traditional patient-centered assessment approach by creating bystander-centered metrics. Instead of measuring only patient outcomes, it measures the witness rate (how many patients were witnessed) and witness action rate (how many witnesses took action), thereby assessing organizational performance from the perspective of bystander engagement and effectiveness.

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The patent changes the assessment parameters from clinical outcome measures to behavioral engagement measures. By introducing witness rate and witness action rate as key parameters, the system enables ease of operation in assessing bystander and organizational performance while maintaining reliability through the structured calculation of rescue action conversion efficiency.

Inventive Principle:
Principle #35Parameter changes

3Area of stationary object

If EMS response time is extended beyond golden hour, then coverage area is improved, but survival rate from cardiac arrest deteriorates

Engineering Contradiction:
ImproveEMS coverage areaVSAvoidcardiac arrest survival rate
Core Design Contradiction:
Area of stationary objectVSReliability

Solution Approach 1:

The patent emphasizes preliminary action by measuring and improving witness intervention before EMS arrival. The rescue action conversion efficiency metric specifically captures actions taken during the critical pre-EMS period, encouraging organizations to train bystanders for immediate intervention rather than relying solely on extended EMS coverage.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements feedback mechanisms through the calculation and analysis of rescue action conversion efficiency. By providing organizations with feedback on their witness rate and witness action rate, the system enables continuous improvement of bystander intervention effectiveness, thereby maintaining high survival rates even when EMS coverage areas are expanded and response times are extended.

Inventive Principle:
Principle #23Feedback

AI summary

A method for evaluating work performance of a target organization includes: acquiring at least one set of witness information data pairs within a business coverage area of the target organization and within a preset historical time period, each set of witness information data pairs including a witness rate and a witness action rate; calculating a rescue action conversion efficiency corresponding to the target organization based on the at least one set of witness information data pairs; and evaluating the work performance of the target organization based on the rescue action conversion efficiency corresponding to the target organization.
