Anonymized Medication Vending Data Recording for eMAR Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medication dispensing devices do not adequately address patient privacy issues and fail to efficiently record and manage medication adherence data, particularly in the context of medication vending machines.
Innovation Solution
An automated system for recording medication package contents from vending machines into electronic records, using a network of portable medication vending devices (PMVDs) that communicate with a host site to populate electronic medication administration records (eMARs) without revealing patient names or medication details, employing HL7 protocol for data conversion and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If patient names and medication details are communicated in electronic messages from vending machines, then complete medication adherence data can be recorded, but patient privacy is compromised
Solution Approach 1:
The patent extracts and removes personally identifiable information (patient names) and sensitive medication details from the electronic communication between vending machines and the central system. Only anonymized data such as vending machine identifiers, timestamp, and medication package identifiers are transmitted, allowing complete tracking of medication adherence while preserving patient privacy.
Solution Approach 2:
The system introduces an intermediary layer of anonymization between the vending machine and the central recording system. A unique identifier system acts as a mediator that links vending events to patients through secure mapping without exposing personal information in the communication stream, thus protecting privacy while maintaining data completeness.
2Productivity
If manual recording of medication administration is used, then patient privacy is maintained, but medication adherence tracking efficiency is reduced
Solution Approach 1:
The vending machine system performs self-recording of medication administration events. When a medication package is vended, the system automatically captures the event data, anonymizes it, and transmits it to the central system without requiring manual intervention from healthcare providers or patients, thus maintaining high tracking efficiency while preserving privacy through automated anonymization.
Solution Approach 2:
The patent replaces manual mechanical recording processes with an automated electronic system that uses electronic messages and data transmission. The vending machine's controller automatically generates and sends electronic records of medication dispensing events, eliminating the need for manual charting or paper-based tracking while maintaining privacy through automated data anonymization protocols.
3Measurement precision
If detailed medication information is transmitted from vending machines, then accurate eMAR population is achieved, but data security and patient confidentiality are compromised
Solution Approach 1:
The system extracts only the essential elements needed for accurate medication recording (medication package identifier, vending time, vending machine identifier) while removing sensitive information (patient name, detailed medication descriptions) from the transmitted data. This allows the electronic medication administration record to be accurately populated with vending event data while maintaining data security and patient confidentiality.
Solution Approach 2:
The patent transforms the data parameters being transmitted by changing from personal identifiable information to anonymized identifiers. The system uses unique vending machine identifiers and medication package identifiers instead of patient names and detailed medication information, maintaining the precision needed for accurate tracking while improving data security through parameter transformation.
Data Source
AI summary
An automated method is provided for recording contents of medication packages vended from a plurality of vending machines in electronic records, such as an electronic medication administration record (eMAR), that store records for a plurality of patients who are associated with respective vending machines. A vending event causes the electronic record to be populated. The contents of the medication packages vended from the vending machines are recorded in electronic records without communicating patient names or vended medications in the electronic message sent from the vending machines.
