Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pathology laboratories face challenges in accurately determining costs and error rates due to the complexity of their workflows, which involve multiple resources and labor, and existing tracking processes fail to account for variables like employee labor, machine use, service, depreciation, and error rates effectively.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional tracking processes are used to monitor consumable use, then consumable tracking is simple, but cost accuracy and error rate assessment are insufficient
Solution Approach 1:
The system segments workflow tracking by dividing the laboratory into multiple stations (accessioning, grossing, histotech, pathologist review) and tracking specimens through each station individually. This segmentation enables accurate attribution of labor costs, machine usage, and error rates to specific stations and operators, resolving the contradiction between measurement precision and system complexity by organizing data collection into manageable modular units.
Solution Approach 2:
The system implements continuous feedback loops where performance data (costs, error rates, time utilization) is collected from each station, analyzed by the processor, and used to generate reports that feed back into workflow optimization decisions. This feedback mechanism enables accurate cost assessment while maintaining systematic organization, allowing the complex tracking requirements to be met through structured data collection and analysis.
2Productivity
If multiple resources and labor are involved in specimen processing, then workflow capability is enhanced, but difficulty in determining costs and error rates increases
Solution Approach 1:
The system creates a universal tracking framework that handles multiple resource types (labor, consumables, machine usage) and multiple workflow stages through a single integrated platform. The processor universally applies the same data collection and analysis methods across all stations and resource types, enabling accurate cost determination despite the diversity of resources involved in specimen processing.
Solution Approach 2:
The system introduces an intermediary tracking layer between the physical workflow and cost analysis. This intermediary system (the computer system with processor) captures data from all resources and labor involved in specimen processing, translates diverse operational data into standardized cost metrics, and presents unified cost and error rate information, thereby simplifying the measurement process while maintaining comprehensive workflow capability.
3Adaptability or versatility
If workflow variations exist between laboratories, then adaptability is improved, but obtaining accurate cost accounting becomes difficult
Solution Approach 1:
The system is designed to be dynamic and adaptable to different laboratory workflows. The computer system can accommodate variations in station configurations, process sequences, and resource allocation across different laboratories. The processor dynamically adjusts data collection parameters and analysis methods based on the specific workflow configuration, enabling accurate cost accounting regardless of workflow variations while maintaining precision through flexible adaptation rather than rigid standardization.

AI summary
A computer system for analyzing a specimen processing workflow in a pathology laboratory including a display and a processor configured to provide a first interface, a second interface, and a third interface to the display, receive, via the first interface, a first set of parameters associated with an existing specimen processing workflow in a pathology laboratory, the first set of parameters including a workflow process and a workflow scale, and determine, based on the first set of parameters, current performance data of the existing specimen processing workflow having an associated current cost information and current time utilization. The processor may further be configured to receive, via the second interface, a second set of parameters associated with a proposed modification to the existing specimen processing workflow, the second set of parameters including parameters associated with at least one laboratory device, determine, based on the first and second sets of parameters, revised performance data having an associated revised cost information and revised time utilization, and provide an output comprising a comparison between revised performance data and the current performance data.
