Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The uncertainty in medical image interpretation times for cardiologists leads to inefficiencies in workflow management, as hospitals struggle to allocate resources effectively due to varying interpretation times based on disease type, clinical features, and image complexity, which complicates adherence to service level agreements.
Innovation Solution
A method and system using a regression-based artificial intelligence algorithm that predicts interpretation times for medical images by analyzing data inputs such as patient characteristics and imaging modalities, providing a confidence level and ranking interpretation times to optimize workflow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If cardiologists process examinations following first-in first-out principle or select less complex exams first, then workflow management is simplified, but productivity and health outcome quality are not optimized due to interpretation time uncertainty
Solution Approach 1:
The system performs preliminary action by predicting interpretation times for examinations before they are assigned to cardiologists. The prediction engine calculates expected interpretation durations based on examination characteristics, allowing the worklist manager to pre-optimize assignment sequences that maximize productivity while maintaining simple workflow operations.
Solution Approach 2:
The system implements feedback by continuously monitoring actual interpretation times and using this data to refine prediction accuracy. The worklist manager receives feedback on cardiologist performance and examination complexity, adjusting future assignments to optimize productivity while keeping the workflow simple for cardiologists to follow.
2Device complexity
If hospitals assign attending cardiologists by day of the week, then resource allocation is simplified, but interpretation time uncertainty makes it difficult to manage service level agreements and complete interpretations within required timeframes
Solution Approach 1:
The system performs preliminary action by predicting interpretation times before examinations are assigned to cardiologists. This allows the worklist manager to pre-calculate optimal assignment sequences that ensure service level agreement compliance while maintaining simple day-of-the-week assignment structures for cardiologists.
Solution Approach 2:
The system implements dynamics by making the worklist assignments adaptive rather than static. While cardiologists are assigned by day of the week, the specific examinations assigned to each cardiologist are dynamically optimized based on predicted interpretation times, examination complexity, and current workload, ensuring service level agreement compliance without increasing operational complexity.
3Quantity of substance
If more patients are accepted to increase hospital capacity, then revenue and patient care coverage improve, but reading efficiency and time spent by cardiologists become critical bottlenecks
Solution Approach 1:
The system performs preliminary action by predicting interpretation times for all pending examinations before cardiologists begin work. This allows the worklist manager to pre-optimize assignment sequences that maximize cardiologist productivity, enabling the hospital to accept more patients while maintaining efficient reading workflows through data-driven examination sequencing.
