Pharmacy Will-Call Inventory Management for Unclaimed Medication Reuse
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing will call systems in pharmacies often incorrectly assume sold prescriptions, leading to unclaimed medications being returned to stock after a lengthy period, wasting resources and causing inventory management challenges, as they do not account for medications that remain unclaimed for extended periods.
Innovation Solution
A system that places filled prescription vials in a 'sales pending' state, allowing unclaimed medications to be reused for other prescriptions, with a storage unit that tracks and manages inventory, automatically returning unclaimed items to stock after a predetermined period, and a kiosk system for efficient dispensing and customer interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If filled vials are stored in a will call system for extended periods to allow customer pickup, then customers have sufficient time to claim their prescriptions, but unclaimed medications are incorrectly assumed to be sold and are returned to stock, causing waste and inventory management issues
Solution Approach 1:
The system performs preliminary actions by maintaining filled vials in a 'sales pending' state with a timer mechanism before returning them to stock. The control system monitors the time elapsed since filling and only returns vials to stock after the predetermined time period expires, preventing premature restocking of unclaimed medications and eliminating waste associated with incorrect inventory management assumptions
Solution Approach 2:
The control system continuously monitors the status of filled vials in the will call system, tracking whether they have been claimed by customers. This feedback mechanism allows the system to distinguish between claimed and unclaimed vials, preventing the incorrect assumption that all unclaimed vials are sold, and thereby avoiding the waste of returning potentially usable medications to stock
2Ease of operation
If a traditional will call system is used to store filled prescriptions, then customers can pickup their orders, but the system lacks visibility of unclaimed items and cannot automatically manage inventory returns
Solution Approach 1:
The will call system is enhanced with multi-functionality by integrating a control system that performs multiple functions: storing filled vials, tracking their status, monitoring time elapsed, determining whether they are claimed or unclaimed, and automatically returning them to stock. This universal system eliminates the need for separate manual inventory management processes while maintaining ease of customer pickup
Solution Approach 2:
The enhanced will call system provides self-service capabilities by automatically monitoring and managing inventory without requiring manual intervention. The control system autonomously tracks unclaimed vials and returns them to stock based on predetermined time periods, eliminating the need for manual inventory audits and management while maintaining simple customer interaction
3Quantity of substance
If unclaimed medications are returned to stock after extended periods, then inventory space is freed up, but resources are wasted and inventory accuracy is compromised
Solution Approach 1:
The system performs preliminary time monitoring and status verification before returning vials to stock. By tracking the time elapsed since filling and confirming the vials are truly unclaimed (not merely undispensed), the system ensures inventory accuracy is maintained while still freeing up storage space through timely restocking of genuinely available medications
4Productivity
If filled vials are immediately returned to stock after filling, then inventory turnover is improved, but unclaimed medications are lost and cannot be reused for other prescriptions
Solution Approach 1:
The system performs preliminary time monitoring before returning vials to stock, maintaining them in a 'sales pending' state for a predetermined period. This preliminary action allows the system to capture and reuse unclaimed medications for other prescriptions during the monitoring period, preventing waste while still achieving timely inventory turnover through automated restocking of confirmed unclaimed items
Solution Approach 2:
The system recovers unclaimed medications by maintaining them in the will call system beyond the initial filling time, allowing them to be reused for other prescriptions. Only after the predetermined time period expires and the vials are confirmed unclaimed are they returned to stock, maximizing resource utilization while maintaining efficient inventory turnover

AI summary
A method of filling prescription orders includes inputting the prescription orders into a pharmaceutical storage and retrieval device, processing the prescription orders with the pharmaceutical storage and retrieval device to fill a plurality of vials with desired pharmaceuticals, and transferring the plurality of filled vials from the pharmaceutical storage and retrieval device to a storage unit. The method also includes storing the plurality of filled vials in the storage unit until a customer claims one of the plurality of filled vials and directing the one of the plurality of filled vials from the storage unit to the customer.
