Solution Overview

Problem

Emergency medical services (EMS) agencies face challenges in accurately and efficiently capturing electronic patient care record (ePCR) data during pre-hospital and acute care treatment, often due to limited information available and the need for rapid decision-making.

Innovation Solution

A patient data charting device equipped with a processor, memory, and output devices, capable of automatically capturing ePCR data through speech-to-text conversion, image processing, and predictive workflows, guiding caregivers with prompts and ensuring data accuracy and completeness.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual data entry is used for ePCR, then data accuracy can be maintained, but time consumption and cognitive load increase significantly

Engineering Contradiction:

Improvedata accuracyVSAvoidtime consumption

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The patent replaces manual mechanical data entry with automated speech recognition and natural language processing systems. The speech-to-text conversion and NLP algorithms automatically capture and structure ePCR data from caregiver speech, eliminating the need for manual typing while maintaining data accuracy through automated validation and formatting processes.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system enables self-service data capture where the caregiver's natural speech is automatically transcribed, structured, and populated into the ePCR system without requiring manual intervention. The automated system serves itself by identifying data fields, validating entries, and guiding subsequent data collection based on procedural relationships.

Inventive Principle:

Principle #25Self-service

2Loss of information

If comprehensive ePCR data collection is implemented, then completeness of medical record improves, but complexity of data entry increases

Engineering Contradiction:

Improvecompleteness of medical recordVSAvoidcomplexity of data entry

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

The system implements feedback mechanisms where the automated system analyzes captured speech, identifies which data fields have been populated, and generates prompts for missing information based on procedural relationships. This feedback loop ensures comprehensive data collection by systematically guiding caregivers through required fields while adapting to the current state of the medical record.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system performs preliminary actions by pre-identifying procedurally related data fields and preparing guided prompts before the caregiver completes data entry. The system analyzes the current ePCR state and proactively determines what additional information is needed, organizing the data collection process in advance rather than reactively.

Inventive Principle:

Principle #10Preliminary action

3Productivity

If automated speech-to-text conversion is used, then data capture speed improves, but accuracy of data interpretation may decrease

Engineering Contradiction:

Improvedata capture speedVSAvoidaccuracy of data interpretation

Core Design Contradiction:

ProductivityVSMeasurement precision

Solution Approach 1:

The patent replaces manual data interpretation with advanced natural language processing and speech recognition algorithms. These automated systems convert speech to text and interpret medical terminology with high accuracy, maintaining or exceeding the precision of manual interpretation while dramatically increasing data capture speed through parallel processing capabilities.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system uses a composite approach combining multiple technologies: speech recognition, natural language processing, contextual analysis, and validation algorithms work together in an integrated system. This composite technological approach ensures accurate interpretation of speech by leveraging the strengths of each component technology to compensate for individual limitations.

Inventive Principle:

Principle #40Composite materials

AI summary

A patient data charting device configured to automatically capture electronic patient care record (ePCR) data from a caregiver is provided. The device includes a memory storing an ePCR including a plurality of data fields, an output device, a microphone configured to acquire speech, and a processor. The processor is configured to convert the speech to text, identify a first value of a data field of the plurality of data fields based on the text, populate the first data field with the first value, generate a prompt that requests a second value of a second data field of the plurality of data fields based on the first data field, and present the prompt to the caregiver via the output device.
