Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pharmaceutical items in healthcare environments are difficult to track due to issues like waste, loss, or abuse, and there is a challenge in identifying equivalent pharmacy items and communicating event data without exposing personal health information.
Innovation Solution
The implementation of an RFID-based system that includes pharmacy bins with RFID-tagged containers, an RFID reading and processing system, and a verification environment to associate information across multiple healthcare systems, allowing for dynamic scanning of RFID tags, determination of pharmacy item equivalence, and secure communication of event data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual tracking methods are used for pharmacy items, then simplicity of operation is maintained, but tracking accuracy and reliability deteriorate due to waste, loss, or abuse
Solution Approach 1:
The patent replaces manual tracking mechanisms with an automated RFID-based tracking system. RFID tags are attached to pharmacy items and readers are positioned throughout the healthcare environment to automatically detect and track item movement, eliminating the need for manual logging and significantly improving tracking reliability without requiring direct human intervention
Solution Approach 2:
The patent creates a virtual representation of pharmacy items through RFID tags that contain unique identifiers. These digital copies enable the system to track and monitor physical items remotely, allowing multiple readers to detect the same item and create a comprehensive tracking record that improves reliability while reducing the need for physical surveillance
2Measurement precision
If detailed pharmacy item data is communicated between systems, then tracking precision is improved, but patient privacy protection deteriorates due to exposure of personal health information
Solution Approach 1:
The patent extracts only the essential tracking information (RFID tag identifiers, timestamps, location data) from complete pharmacy records and communicates this subset between systems. By separating tracking data from sensitive patient information, the system achieves precise tracking while minimizing privacy risks through selective data extraction
Solution Approach 2:
The patent introduces an intermediary processing layer that receives data from multiple healthcare systems, anonymizes or pseudonymizes the information, and then shares only the necessary tracking elements. This intermediary acts as a buffer that protects patient privacy while enabling cross-system tracking precision through standardized, de-identified data exchange
3Reliability
If multiple healthcare systems are integrated to track pharmacy items, then tracking completeness is improved, but system complexity and difficulty of operation increase
Solution Approach 1:
The patent implements a universal RFID tracking standard that can be deployed across multiple different healthcare systems simultaneously. The same RFID tags and readers used for pharmacy item tracking can also track other healthcare assets, creating a multi-functional system that improves tracking completeness across all systems while using a single, standardized operational approach
Solution Approach 2:
The patent enables systems to automatically exchange and reconcile tracking data without requiring manual intervention. The RFID readers automatically detect items, log transactions, and communicate with central and external systems, allowing the network to self-maintain tracking completeness across multiple healthcare facilities while reducing operational burden
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution enables efficient tracking of pharmacy items, reduces waste and loss, facilitates the identification of equivalent items, and ensures secure communication of event data, thereby improving inventory management and compliance with privacy regulations.
Implementation Method 1
The RFID reading station 220 can include an RFID reader 222 and an antenna 224. The RFID reader 222 can control the antenna 224 to emit a radio signal that activates an RFID tag
Data Source
AI summary
A system and method for determining event discrepancies between disparate systems is described. The system can receive sets of events from multiple systems. The system can normalize the sets of events to convert them into normalized events. From a normalized set of events, the system can concurrently generate a plurality of event arrays. The system can apply one or more rules to the event arrays to generate at least one event array parameter.
