GENERIC RIS WORKFLOW MODEL
1. Requisition (patient ID and patient history) 2. Order (RIS), RIS to PACS 3. Prepares room, retrieve the patient, input of patient history on paper requisition or input electronically 4. Perform examination, images sent to PACS device 5. Reading of radiologist (comparing of previous images to current images) 6. Report transcribing, signing
46
RIS when integrated with PACS, it includes --- data and workflow.
patient- related PACS
47
RIS when integrated with PACS, it includes patient- related PACS data and workflow. MAJOR TASK INCLUDES:
A. Process patient and film (image) folder records B. Monitor the status of patients, examinations, and examination resources. C. Schedule examinations D. Create, format, and store diagnostic reports with digital signatures E. Track film (softcopy) folders F. Maintain timely billing information G. Perform profile and statistics analysis PM PM CTS
48
3 systems involved in INTERFACING PACS AND RIS
A. WORSTATION EMULATION B. DATABASE-TO-DATABASE TRANSFER C. INTERFACE ENGINE EDI
49
Physical connection (cables) and data fromats (DICOM & HL7) to allow seamless data exchange
Interfacing
50
Process of replicating behavior of a system
Emulation
51
allows a WS of an information system to emulate a WS of a second system so that data from the second information system can be accessed by the first system.
WORSTATION EMULATION
52
allows two or more networked information systems to share a subset of data by storing them in a common local area.
DATABASE-TO-DATABASE TRANSFER
53
Query protocol
INTERFACE ENGINE
54
Responsible for analyzing the requested information, identifying the required databases, fetching the data, assembling the results in a standard format, and presenting them at the requested WS.
INTERFACE ENGINE
55
REASONS FOR INTERFACING PACS AND RIS
1. DIAGNOSTIC PROCESS 2. PACS Image Management 3. RIS Administration 4. Research and Training DPR RT
56
Retrieval of not only images of interest but also pertinent textual information describing patient history and studies.
DIAGNOSTIC PROCESS
57
Along with the image data and the image description, a PACS also provides all the related textual information acquired and managed by the RIS and the HIS in a way that is useful to the radiologist during this reason for interfacing PACS and RIS
DIAGNOSTIC PROCESS
58
Some information provided by the RIS can be integrated into PACS image management algorithms to optimize the grouping and routing of image data via the network to the requesting locations.
PACS Image Management
59
The PACS can provide the image archive status and the image data file information to the RIS. RIS administration operations would also benefit from the HIS by gaining knowledge about patient ADT (admissions, discharges and transfers)

Interfacing Common Guidelines Each system (HIS, RIS, PACS) remains unchanged in its (1), (2), and (3).
1. configuration 2. data 3. functions
62
Interfacing Common Guidelines Each system is extended in both hardware and software for ---.
allowing communications with other systems
63
Interfacing Common Guidelines Only (1) are shared; (2) remain local. For example, RIS functions cannot be performed at the PACS or at the HIS WS. Keeping each system (3) and (4) will simplify the interface process, because (5) are not allowed at a global level.
1. data 2. functions 3. specific 4. autonomous 5. database updates
64
What does it mean for funtions to remain "local"?
functions will remain within the hsopital only
65
Following these guidelines, successfully interfacing HIS, RIS, and PACS requires the following steps:
1. Identify the subset data that will be shared by other systems. Set up access rights and authorization. 2. Convert the subset data to HL7 standard form. This step, consisting of designing a high-level presentation, solving data inconsistencies, and naming conventions, can be accomplished by using a common data model and data language and by defining rules of correspondence between various data definitions. 3. Define the protocol of data transfer (e.g., TCP/IP or DICOM).
