Offline ePCR Validation on Mobile Devices for EMS Compliance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing EMS systems face challenges in efficiently and accurately creating electronic patient care records (ePCRs) due to their complexity and the need for compliance with various governmental reporting guidelines, often requiring network connectivity for validation, which is not always feasible in emergency situations.
Innovation Solution
A system and method for locally validating ePCRs on mobile devices without network connectivity, using a syntax conversion to enable real-time validation of data entries against predefined rules, providing immediate feedback on errors or warnings, and allowing offline locking of records.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If ePCR validation is performed on a remote server via network connection, then validation accuracy and compliance checking are improved, but system reliability deteriorates when network connectivity is unavailable
Solution Approach 1:
The patent introduces an intermediary component - a syntax conversion service that translates validation rules from Schematron syntax to JavaScript syntax. This conversion enables the validation logic to be executed locally on mobile devices while maintaining the same validation accuracy as server-based validation, thus resolving the contradiction between validation precision and system reliability during offline operations
Solution Approach 2:
The system performs preliminary actions by pre-converting validation rules into executable JavaScript code and storing them locally on mobile devices before offline operations begin. This preliminary conversion enables the device to perform accurate validation independently without real-time network connectivity, thereby improving reliability while maintaining validation accuracy
2Ease of operation
If ePCR validation rules are converted from Schematron syntax to JavaScript syntax for local execution, then ease of operation is improved by enabling offline validation, but device complexity increases
Solution Approach 1:
The patent extracts the validation rule conversion functionality into a separate syntax conversion service that transforms complex Schematron rules into simpler JavaScript code. This extracted conversion layer handles the complexity externally, allowing the mobile device to execute only the converted JavaScript validation logic, thereby improving ease of operation while managing device complexity through separation of concerns
3Productivity
If validation is performed in real-time during data entry, then productivity is improved by providing immediate feedback, but device complexity increases due to continuous validation processing
Solution Approach 1:
The system implements real-time feedback validation that provides immediate feedback to users during data entry. The JavaScript-based validation engine continuously monitors input fields and provides instant validation feedback without requiring complex batch processing, thus improving productivity while keeping device complexity manageable through efficient event-driven validation triggers
Data Source
AI summary
A system for locally validating an electronic patient care record (ePCR). The system includes a server and a mobile computing device. The server is configured to convert a standard set of rules from the first syntax to a second syntax that is executable within an execution environment and to communicate the standard set of rules to the mobile computing device. The mobile computing device is configured to host, while operating in an offline mode, an ePCR application encoded in the second syntax. The mobile computing device is configured to execute, within the execution environment, at least a portion of the ePCR application to receive at least one ePCR data value via at least one user interface control, and to execute, within the execution environment, at least a portion of the standard set of rules encoded in the second syntax to validate the at least one ePCR data value.
