Solution Overview

Problem

Hospital ICU workers are overwhelmed by excessive and often false alarms, lacking adequate tools to understand alarm environments or evaluate patient-specific effects of alarm threshold changes, leading to alarm fatigue and potential patient distress.

Innovation Solution

A Patient Alarm Data Application that provides a patient-specific user interface for clinical personnel, allowing for remote monitoring and analysis of physiological data, displaying alarm and vital signs information graphically, and calculating the impact of alarm threshold settings to help clinicians make informed decisions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If alarm thresholds are set to detect all potential patient issues, then patient safety monitoring is improved, but alarm overload and false alarms increase significantly

Engineering Contradiction:
Improvepatient safety monitoringVSAvoidalarm frequency
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The system applies different alarm threshold settings and monitoring parameters to different patients based on their individual clinical characteristics, diagnoses, and risk factors. This patient-specific customization allows each patient to receive appropriate monitoring intensity without contributing to overall alarm overload in the unit.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system pre-calculates and stores historical alarm data and vital signs information before clinical decisions are made. This preliminary preparation of data allows clinicians to evaluate the potential impact of threshold changes before implementing them, enabling proactive optimization of alarm settings to reduce false alarms while maintaining safety.

Inventive Principle:
Principle #10Preliminary action

2Ease of operation

If clinicians adjust alarm thresholds to reduce alarm fatigue, then alarm overload is reduced, but monitoring precision and patient safety may be compromised

Engineering Contradiction:
Improvealarm managementVSAvoidalarm threshold accuracy
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The system provides feedback to clinicians by displaying the estimated impact of proposed threshold changes on alarm frequency and patient monitoring coverage. This feedback loop enables clinicians to make informed decisions that balance alarm reduction with maintaining appropriate monitoring precision, preventing both alarm fatigue and inadequate monitoring.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system allows dynamic adjustment of alarm threshold parameters based on patient condition changes, clinical guidelines, and historical data analysis. By enabling parameter optimization rather than fixed thresholds, the system maintains measurement precision while adapting to reduce unnecessary alarms as patient conditions evolve.

Inventive Principle:
Principle #35Parameter changes

3Loss of information

If comprehensive alarm data is collected and analyzed, then understanding of alarm environments is improved, but system complexity and data processing requirements increase

Engineering Contradiction:
Improvealarm environment understandingVSAvoiddata analysis system
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The system extracts and separates specific alarm-related data elements from the overall patient monitoring system, focusing analysis on relevant alarm parameters and vital signs. This extraction approach provides comprehensive alarm environment understanding without requiring complex analysis of all possible monitoring data, reducing system complexity while maintaining analytical depth.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

A patient alarm application provides a way for allowing clinical personnel to monitor and control patient-specific alarm settings. A user interface allows clinical personnel to compare graphical representations of unit population vital signs data with patient-specific vital signs data as well timelines of alarms for the patient. Analysis of the alarm data allows the user interface to show clinical personnel the estimated effects of changes to alarm threshold settings.
