Solution Overview

Problem

Existing clinical alert systems overwhelm clinicians with excessive alerts, leading to alert fatigue and neglect of contextual patient information, which is subjective and not readily measured by clinical devices, resulting in potential misdiagnosis and suboptimal care.

Innovation Solution

A method and system that apply alert filters to patient data to determine borderline classification decisions, issuing contextual data alerts to clinicians only when filter conditions contradict the classification decision, prompting consideration of contextual information such as patient mood, appearance, and treatment response.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If contextual data is included in clinical assessments, then diagnostic accuracy is improved, but alert fatigue increases due to excessive alerts

Engineering Contradiction:
Improvediagnostic accuracyVSAvoidalert fatigue
Core Design Contradiction:
Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The system applies different alerting strategies to different patient cases based on their characteristics. By identifying cases with high uncertainty in classification decisions, the system selectively prompts clinicians for contextual data only when needed, rather than universally alerting for all cases. This localized approach maintains diagnostic accuracy for complex cases while avoiding alert fatigue for straightforward cases.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system dynamically adjusts the threshold for prompting contextual data based on the confidence level of classification decisions. When the classification decision is uncertain (close to the decision boundary), the system changes the parameter of alerting behavior to prompt for contextual data. This parameter change enables the system to maintain high diagnostic accuracy for borderline cases while reducing unnecessary alerts for confident classifications.

Inventive Principle:
Principle #35Parameter changes

2Measurement precision

If clinicians are alerted to consider contextual information, then diagnostic accuracy improves, but clinician workload increases

Engineering Contradiction:
Improvediagnostic accuracyVSAvoidclinician workload
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

Instead of universally prompting clinicians for contextual data in all cases, the system applies partial action by selectively prompting only for cases where the classification decision is uncertain. This partial approach ensures that clinicians are not burdened with unnecessary data collection for straightforward cases, thereby reducing overall workload while maintaining diagnostic accuracy for the subset of cases that truly require contextual information.

Inventive Principle:
Principle #16Partial or excessive action

Solution Approach 2:

The system performs self-assessment of classification confidence and automatically determines when contextual data is needed, eliminating the need for clinicians to manually evaluate each case. The automated identification of uncertain cases reduces the cognitive burden on clinicians and allows them to focus their effort only on cases where it is most needed.

Inventive Principle:
Principle #25Self-service

3Object-affected harmful factors

If alert filters are applied to reduce false alerts, then alert fatigue decreases, but false negatives may increase

Engineering Contradiction:
Improvealert fatigueVSAvoidfalse negative rate
Core Design Contradiction:
Object-affected harmful factorsVSReliability

Solution Approach 1:

The system incorporates feedback loops where clinicians can provide input on classification decisions, and this feedback is used to refine future classification and alerting behavior. This feedback mechanism ensures that the system learns from past interactions and adjusts its alerting strategy to reduce false negatives while maintaining low false alert rates, thereby balancing alert fatigue reduction with diagnostic reliability.

Inventive Principle:
Principle #23Feedback

AI summary

Methods and systems for managing alerts. The methods and systems described herein receive a classification decision related to a patient. If the classification decision is a borderline classification decision, the systems and methods described herein apply one or more alert filters to patient data to determine an alert filter condition. Upon determining the alert filter condition contradicts the borderline classification, the systems and methods may issue a contextual data alert to a clinician to prompt the clinician to consider contextual data related to the patient.
