Anatomical Sensor Tagging for Misplacement-Aware CDS Inputs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clinical decision support systems are susceptible to inaccuracies due to incorrect placement of monitoring devices, leading to misrepresentation of physiological data and incorrect clinical decision recommendations.
Innovation Solution
A system that uses a reference image to tag monitoring devices to specific anatomical locations, monitors signal quality, and alerts clinicians to misplacement, automatically pausing data transmission from misplaced devices to ensure accurate data input to the CDS system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If monitoring devices are placed on patient without verification, then ease of operation is improved, but measurement precision deteriorates due to incorrect anatomical location
Solution Approach 1:
The system provides automatic feedback by monitoring signal quality indicators and comparing actual device locations with expected anatomical locations. When a mismatch is detected, the system alerts the user and prevents data transmission, creating a closed-loop verification system that maintains measurement precision without significantly increasing operational complexity.
Solution Approach 2:
The system performs preliminary verification of device placement by checking signal quality and anatomical location matching before allowing data to be transmitted to the CDS system. This preliminary action ensures that only correctly placed devices contribute to clinical decisions, maintaining measurement precision while keeping the placement process straightforward.
2Measurement precision
If automatic monitoring of device placement is implemented, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The monitoring system leverages the existing CDS platform to perform multiple functions: it uses the same interface for clinical decisions, the same communication infrastructure for data transmission, and the same processing capabilities for analyzing signal quality and detecting misplacement. This multi-functionality approach maintains measurement precision while minimizing the addition of separate complex subsystems.
Solution Approach 2:
The system performs self-verification by automatically monitoring its own device placement status through signal quality indicators and anatomical location comparison. The CDS system itself serves as the monitoring mechanism, eliminating the need for separate external verification equipment and reducing overall system complexity while maintaining high measurement precision.
3Measurement precision
If data from misplaced devices is excluded, then measurement precision is improved, but productivity decreases due to reduced data availability
Solution Approach 1:
The system provides immediate feedback when device misplacement is detected, alerting users in real-time. This allows for rapid correction of placement issues, minimizing the duration during which data is excluded. The feedback mechanism ensures that only briefly excluded data affects productivity, while measurement precision is maintained for the majority of the monitoring period.
Solution Approach 2:
The system excludes data on a partial basis - only from specifically misplaced devices rather than from all monitoring data. This selective exclusion maintains measurement precision for correctly placed devices while preserving productivity by continuing to collect and analyze data from properly positioned sensors, ensuring adequate data availability for clinical decisions.
Data Source
AI summary
Systems and methods are disclosed for tagging anatomical locations of monitoring devices on a patient in a reference image on an application. The application excludes data from the monitoring devices from analysis by a clinical decision support system when the monitoring devices are misplaced, for example in locations other than the tagged anatomical locations.
