Variable Dose Medication Dispensing With Waste-Aware Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Healthcare facilities face challenges in minimizing medication waste and controlling access to variable dose medications, as healthcare professionals find it confusing to select the right medication items to administer precise doses, leading to potential over-access and waste.
Innovation Solution
A variable dose dispensing system that includes processors and memory instructions to secure medication containers within automated dispensing devices, determining the most efficient combination of medication amounts to meet the required dose while minimizing waste, and controlling access to ensure precise dispensing and tracking of excess medication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the medication dispensing device allows healthcare professionals to select from various medication items to fulfill variable dose orders, then the flexibility to administer different doses is improved, but the complexity of selection and potential for waste increases
Solution Approach 1:
The system pre-calculates and presents optimized medication combinations to healthcare professionals before the dispensing decision is made. The processor determines the best combination of medication items to fulfill the ordered dose range, and this pre-determined selection is displayed to the user for confirmation, eliminating the need for manual calculation and reducing selection complexity.
Solution Approach 2:
The system automatically determines the optimal medication combination without requiring the healthcare professional to manually calculate or select from multiple options. The processor autonomously analyzes the available medication items, their concentrations, and the ordered dose range to generate the best dispensing solution, making the system self-optimizing.
2Adaptability or versatility
If the medication dispensing device provides access to multiple forms and amounts of medication, then the ability to fulfill variable dose orders is improved, but the likelihood of waste and improper access increases
Solution Approach 1:
The system provides real-time feedback to healthcare professionals about the waste implications of different dispensing options. The interface displays information about the exact amount of medication that will be dispensed versus the ordered dose range, allowing users to make informed decisions that minimize waste while still fulfilling the medical need.
Solution Approach 2:
The system pre-calculates the optimal medication combination before dispensing, determining exactly which items to dispense to minimize waste. This preliminary determination ensures that the healthcare professional only accesses the specific medications needed, preventing unnecessary waste from accessing broader ranges of medication items.
3Ease of operation
If the medication dispensing device allows broad access to medication items for variable dose orders, then the ease of operation is improved, but the control over healthcare professional access is reduced
Solution Approach 1:
The system pre-determines the exact medication items and amounts to be dispensed based on the ordered dose range and available inventory. This preliminary determination is then presented to the healthcare professional for confirmation, maintaining ease of operation through a simple confirmatory action while ensuring control by limiting access to only the pre-approved medication items.
Solution Approach 2:
The system dynamically adjusts the list of accessible medication items based on the specific order parameters and available inventory. Rather than providing static broad access or rigid restrictions, the system adaptively generates a customized list of permissible items for each dispensing event, balancing ease of operation with controlled access.
Data Source
AI summary
A variable dose dispensing system may include a processor and memory. The processor may receive a request for a variable dose order of a medication, such as from a user. The processor may request an amount of the medication to be administered, and receive, in response to the request, an indication of the amount to be administered. The processor may verify that the amount to be administered is within a range of the variable dose order. The processor may determine an item in a local inventory that contains at least the amount of the medication to be administered, and may dispense the item. If an amount of the dispensed item exceeds the amount to be administered, such as by a waste amount, the processor may display an indication of the waste amount to the user, and may transmit a notification of the waste amount, such as to a management server.
