A use case where FHIR SupplyRequest Resource can be utilized

Use Case: Supply Request for Medication Replenishment

Description: In a hospital setting, ensuring a consistent supply of medications to various departments and wards is crucial for providing uninterrupted patient care. However, manual tracking and communication of medication needs can lead to delays and errors. To streamline this process, a digital solution is needed to manage medication supply requests efficiently.

Solution: The FHIR SupplyRequest resource can be utilized to address this use case effectively. When a healthcare provider identifies that a specific medication is running low in a particular ward, they can create a SupplyRequest using an electronic health record (EHR) system or a compatible application. The following steps illustrate the solution:

Creation of SupplyRequest: The healthcare provider accesses the EHR system and creates a new SupplyRequest. They fill in details such as the medication’s identification code, quantity needed, destination ward, and the reason for the request (e.g., low stock).
Automated Communication: The EHR system generates a FHIR-compliant JSON representation of the SupplyRequest. This information includes the medication details, quantity, requesting practitioner’s reference, and the destination ward’s reference.
Interoperable Transmission: The generated JSON is transmitted to the hospital’s central supply management system or pharmacy, which is equipped to handle FHIR resources.
Pharmacy Acknowledgment: The central pharmacy system receives the SupplyRequest and processes it. Upon confirmation of the availability of the requested medication, the pharmacy system can send an acknowledgment message back to the EHR system.
Workflow Optimization: The EHR system updates the medication supply status in real-time based on the acknowledgment received. This information becomes accessible to both the requesting practitioner and the central pharmacy team.
Efficient Fulfillment: The central pharmacy team picks and packages the requested medication, ensuring it’s correctly labeled with the destination ward details.
Delivery and Confirmation: The medication is dispatched to the designated ward. Upon receipt, the ward’s EHR system can trigger an automated confirmation, acknowledging the successful delivery of the medication supply.

By utilizing the FHIR SupplyRequest resource, this solution streamlines the process of medication replenishment in a hospital environment. It enhances communication between healthcare providers and the central pharmacy, reduces delays, minimizes errors, and improves the overall efficiency of medication supply management, ultimately leading to better patient care.
