Solution Overview
Problem
Current Laboratory Information Systems (LIS) lack the ability to manage workflow with laboratory instrumentation, leading to inefficiencies such as redundant data entry, increased error rates, and delayed test results, which can hinder timely and accurate disease diagnosis.
Innovation Solution
A system comprising a single point interface (Interface Point Server) that connects Laboratory Information Systems with automated laboratory instruments, using standardized communication protocols to facilitate bidirectional data exchange, enabling automated data management, reagent optimization, and streamlined clinical pathology processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If Laboratory Information Systems are web-enabled to facilitate access over the Internet, then system accessibility is improved, but the ability to manage workflow with laboratory instrumentation deteriorates
Solution Approach 1:
The system is divided into distinct functional modules: a web-enabled Laboratory Information System for accessibility, an interface server for protocol translation, and laboratory instrumentation for testing. This segmentation allows each component to specialize in its strength while working together through standardized protocols.
Solution Approach 2:
An interface server acts as an intermediary between the web-enabled LIS and laboratory instrumentation. It translates between web protocols and instrument-specific protocols, enabling the LIS to manage instrument workflows despite the protocol incompatibility that would otherwise prevent it.
2Device complexity
If data entry functions are replicated across multiple laboratory instruments, then system connectivity is reduced (simpler architecture), but productivity deteriorates due to time-consuming manual entry
Solution Approach 1:
The interface server provides universal data exchange capabilities that work with multiple different laboratory instruments and protocols. It serves as a multi-functional bridge that can translate to and from various instrument-specific protocols, eliminating the need for separate connectivity solutions for each instrument.
Solution Approach 2:
Instead of replicating data entry functions across multiple instruments (which would simplify connectivity but reduce productivity), the system creates a single point of data entry at the LIS, which then automatically distributes data to all instruments through the interface server. This eliminates redundant manual entry while maintaining system simplicity.
3Device complexity
If data entry is performed manually at each laboratory instrument, then device complexity is reduced, but reliability deteriorates due to increased error rates
Solution Approach 1:
The system enables self-service data management where the LIS automatically performs data entry and distribution to instruments without requiring manual intervention at each device. The interface server autonomously translates and routes data, eliminating human error while keeping individual instruments simple.
Solution Approach 2:
The interface server as an intermediary ensures data accuracy by providing a single controlled point for data entry and translation. It validates and standardizes data before distributing to instruments, preventing the propagation of errors that would occur with manual entry at multiple devices.
4Loss of information
If test status monitoring is implemented, then information availability is improved, but device complexity increases due to additional communication requirements
Solution Approach 1:
The interface server's universal protocol translation capability handles both data entry/distribution and test status monitoring through the same communication infrastructure. This multi-functionality allows comprehensive information availability without requiring separate dedicated communication channels for each function.
