2. The Problem
IHE has defined two profiles regarding how acquisition protocoling is performed and managed. They are Management of Acquisition Protocols and Scheduled Workflow, Assisted Protocol Option. IHE has not defined how these profiles interact.
Management of Acquisition Protocols defines actors, and a centralized process for managing Protocols across modalities, and the SWF.b Assisted Protocol Option provides for the capability to communicate to the acquisition modality, the recommended protocols for the acquisition.
There is a natural grouping of Protocol Management and Protocol Prescription functionalities within the Protocol Manager Actor. Such systems are being developed as standalone systems apart from the traditional Radiology Information System. The RIS typically incorporates this Protocol Prescription capability along with resource (Modality) scheduling, however, the RIS may lack equipment specific knowledge to assign the correct protocol based on the manufacturer and model of the scheduled resource. These new systems include the incorporation of EMR clinical data (such as patient history and allergies) and AI algorithms, to improve the efficiencies of radiologists in prescribing acquisition protocols necessary to fulfill an order.
This proposal is to address how a Protocol Management System communicates to a Radiology Information System the prescription of the acquisition protocols that are known by the performing modality to be scheduled.
3. Key Use Case
An imaging service request is typically created by and EMR and transferred as an imaging order to a Radiology Department Information System.
The order received by the Radiology Information System (EMR), initiates two tasks, Scheduling and Protocolling. These tasks happen independently. In this use case, these tasks are performed on two separate systems, a RIS performing the scheduling and a Protocol Management System performing the protocoling.
When the Order is received by the Protocol Management System, the order is associated with a number of radiology-specific procedures that have to be performed to satisfy the order. Each procedure prescribes a number of actions that are to be performed by Acquisition Modalities. Actions are grouped into procedure steps.
A Radiologist determines the procedure assignment and will recommend the protocols to be performed by the acquisition modalities to fill the order. This includes the acquisition protocol which identifies the settings and conditions to be used by the technologist to perform the acquisition. The Radiologist reviews the patient’s medical history, typically hosted on an EMR, to assist in this assignment. This task is performed on a Protocol Management System.
A Department Scheduler will assign the time slots and performing resource (modality) for the procedure steps. The procedure steps includes the protocol assignments by the Radiologist.
