• Stakeholder Identification
– All information systems implementation projects in the area of health information begin by identifying key stakeholders.
– These stakeholders must work in concert and collaboration in order to achieve their objectives as all of them are involved in the planning and execution of the project (O’Carroll et al., 2003)

• Stakeholder Identification
– O’Carroll et al describe these stakeholders as two camps:
• IT View
• Business View
– Some have suggested that given our field’s stress on the regulatory process that a third camp also be considered:
• QA View

• IT Needs
– How will the integration actually process? • Direct database to database connectivity?
• Web services?
• What is the system architecture being used?
– The unique case ID that intermediate system may generate – is there any value in it being an intelligent key like • <STUDY>_<USUBJID>_<AESEQ>_<SOME_SEQ_NUMBER>
• Or should it be a plain sequence number?
– Is the integration unidirectional or bi-directional between the systems?

• IT Needs Answers in this Practical Example
– How will the integration actually process?
• A combination of database table manipulation in the LSH system resulting in the generation of an E2b(+) XML file that will be moved using Web Services into the appropriate Incoming folder for Argus Interchange
– Is the integration unidirectional or bi-directional between the systems?
• The integration is unidirectional only as the OLX and OC/RDC systems are considered source by this client

• Business Needs
– When should data be triggered for transfer from the source to the target systems? • Daily, Hourly?
– What specific data should be copied from the source to the target system? • All laboratory data?
• All medical history data?
– It is typical practice in a traditional safety practice to only enter the laboratory tests and medical history data for a participant that are deemed “medically relevant” to the event of interest for the case. How does this clinically challenging concept get applied to an information system?

• Business Needs (cont.) • Every event?
– Many companies use Argus to track more than just adverse event data. Some use it to track quality issues, device failure terms, medical information data and registry information just to name a few.
– What constitutes a “case” in the source system?

• Business Needs Used in This Tutorial
– When should data be triggered for transfer from the source to the target systems?
• This example integration has 5 data movements that require scheduling
1. OLX and OC/RDC data into LSH
2. Transformation of LSH data into SDTM standard
3. Creation of E2b(+) XML file from the SDTM standardized data and queue for transfer
4. Transfer of XML file to network share via Web Methods
5. Import into Argus via Interchange

• QA Needs – Most of our client base would see this type of work as custom
development and place a risk level of medium to high in its development
– This would mean a significant amount of testing usually in a phased approach popular with the FDA regulations
• IQ – Installation Qualification
– Phase responsible for the documentation and testing of the installation process according to the system design documentation and usually governed by its own protocol and summary report.
• OQ – Operational Qualification
– Phase responsible for the functional testing of the system according to the functional requirements specification and usually governed by its own protocol and summary report.
• PQ – Performance Qualification
– Phase responsible for the user acceptance testing of the system according to the user requirements specification and usually governed by its own protocol and summary report.

–What is the timeline? Do any of the integrated systems have critical dates that may impact timeline?

Development/Testing
• Development/Testing
– Mapping – Must occur before development begins; iterative process involving users
• Used to identify source for standard E2B fields and to define required extended tags
13
PREVIOUS NEXT
Development/Testing
• Mapping
– First phase of development; Iterative process involving users
– Document the source locations, E2b tags, and Argus target fields
– Map standard E2b tags and define required E2b(+) tags
14
PREVIOUS NEXT
Development/Testing
• Mapping (contd.)
– Source • Multi-record data mapped to repeating E2b sections
• “Where Clause” can be specified for added granularity
• Special consideration given to max. lengths across mapping
– E2b Tag • Leverage default E2b tags where possible
• Define placement and order of E2b(+) tags within standard sections
• E2b(+) tags names: “_EXTENSION” and <= 30 characters in Argus
– Target (Argus) • Identify code list mappings
• Surface user defined fields if necessary
15

Development/Testing
• Development/Testing
– Argus configuration
• Surface UD fields, configure products, studies, etc.
• Enable Interchange and required AG Services
16
PREVIOUS NEXT
Development/Testing
• Synchronize Configuration
– Code Lists • Challenges mapping free-text source to target code lists
• Define process for error handling
• Establish procedure for future updates
17
PREVIOUS NEXT
Development/Testing
• Synchronize Configuration (contd.) – Studies
• Limitations on importing study products (ex. duplicate records)
18
PREVIOUS NEXT
Development/Testing
• Synchronize Configuration (contd.) – Products
• Product names must match Argus Trade Names verbatim
• Evaluate central product repository for ease of integration
19

Development/Testing
• Development/Testing
– Develop Argus custom profile and extended tags • Define custom, extended profile in ESM and custom DTD file
• Load extended tags in CFG_E2B and LM_ESM_ARGUS_MAPPING tables
• Add extended tags to DTD
• Develop custom import/export programming per extended tag.
– Most of the export code is defined at the parent tag level (ex. “drug”) while the import code is defined per tag
– Import code leverages PL/SQL and Argus API while export code is basic SQL

Development/Testing
• Define E2b(+) Tags – Add tags to DTD
• Location must match order in E2b file
Two Places
21

Development/Testing
• Define E2b(+) Tags (cont.) – Insert tag records
• Use SQL*Loader for convenience
• Two tables: CFG_E2B and LM_ESM_ARGUS_MAPPING
22
PREVIOUS NEXT
Development/Testing
• Define E2b(+) Tags (cont.) – Add Receive Code
• PL/SQL block per tag leveraging Argus API
• Helpful to use existing tags as examples
23
PREVIOUS NEXT
Development/Testing
• Define E2b(+) Tags (cont.) – Add Transmit Code
• Only required for outgoing files (i.e. when Argus is the source)
• Basic SQL, usually defined at the parent element level (ex. Patient)
• Verify “Column Position” in CFG_E2B matches SELECT statement order
24
PREVIOUS NEXT
Development/Testing
• Add E2b(+) Profile – Copy existing Profile to create new Profile
– Check “Extended E2b”
25
PREVIOUS NEXT
Development/Testing
• Create E2b(+) Profile DTD – Copy and rename existing DTD
– Link profile to DTD
26
PREVIOUS NEXT
Development/Testing
• E2b Validation Rules – Modify for E2b(+) profile to ease import restrictions
• Incoming files only need to meet minimum Argus case creation requirements (not regulatory ICSR requirements)
• Minimize number of “mandatory” and “mandatory optional” tags
– CFG_E2B Table • Update MANDATORY and MANDATORY_DTD_ELEMENT columns
– CFG_M2_ADDITIONAL Table • Contains additional E2b validation rules
• Rules can be added/removed according to requirements
27

Development/Testing
• Development/Testing
– Configure Integration Points
• Argus reporting destination configured to point to incoming/outgoing directories via Argus ESM (network paths ok)
• Mechanism for moving E2B files to/from directories?
– Web services?

• Include several cycles of end-to-end testing

Implementation/Maintenance
• Implementation/Maintenance – Consider phased rollout – ex. individual studies or limited data
points supplemented by manual data entry
– Define process for configuration changes across systems – Changes can impact multiple systems (ex. configuring a new product or study)
– Define process for bridge modifications (ex. addition of new extended tag)
31
PREVIOUS NEXT
• Gotchas (examples)? – Synchronizing configuration across systems (ex. product configuration)
– E2B tag order must be appropriately configured within CFG_E2B table and match export SQL select order
– Extended tag names cannot exceed 30 characters
– Cannot add new parent tags or repeating sections
– Default logic for importing study products (potential for duplicate products) • Argus creates a single study product even if multiple products are delivered
to the patient
– Carefully consider enabling Argus auto-acceptance • Business implications
– Known limitations with device products
– Working within standard E2B specification • eMDR standards use HL7 formatted files
– Argus does not delete records or clear out values on import of follow-ups
