RIS-PACS
Descriptors and
Coding
Dr Keith Foord
Consultant Radiologist, East Sussex Hospitals
A national system of RIS coding
and descriptors ? Why?
Must be as intuitive and easy to use as possible
Should have national acceptance



Relates to needs of request/entry systems within NCRS – preRIS - SNOMED match to record request to Spine
Consistency and uniqueness in requesting terminology – preRIS and within RIS
Consistency in activity measurement - RIS
Consistency in clinical coding of events – RIS - SNOMED match
For accurate communication of results data between hospitals –
post RIS results reporting, cluster stores and national spine SNOMED match to ‘performed examination code’ to Spine
For ‘Payment by results’ – accurate records of same patient
activity – national tariffs - SNOMED match / accurate HRGs

Descriptors
Descriptors need to be UNIQUE in NCRS
FOOT LEFT not unique
When a user searches all of the examinations available for ‘Foot Left’
the search may return:
FOOT LEFT, FOOT LEFT Swab, FOOT LEFT Physiotherapy,
FOOT LEFT Dressing,
etc., etc.
But XR FOOT LEFT is unique
Radiology Short Codes
Used in RIS as shortcuts
For bookings
For internal communications within Radiology
To help group procedures
For internal management / audit / activity
For common use need a structure, ideally
short (max. 6 letters/digits) and logical

Pre and Post Co-ordination (1)




In order to group procedures many old RIS systems
lack the ability to post co-ordinate procedures together
under one accession number.
Particular examples are for 'both' plain film exams eg
'both ankles' and in CT where examinations often
combine e.g. CT Chest, Abdomen, Pelvis.
Pre co-ordination or grouping of these procedures is
therefore required in advance.
Pre co-ordination should not be used in RIS-PACS
systems capable of full post co-ordination as within
these individual procedure codes will be automatically
or manually grouped prior to archiving and reporting
Eg CT guided PELVic Biopsy
CPEL VB
This is pre-coordinated with the whole
process described in the code
Pre and Post Co-ordination (2)
In modern RIS systems post co-ordination can be
applied to group related procedures together. All RIS
systems supplied via LSPs should do this.
 Some procedure codes such as 'U/S biopsy' by
themselves do not define precisely what has
happened although it would define the activity of
“Performing a biopsy under ultrasound control and the
consumables/activity associated with this.”
 Such codes need post co-ordinating with the relevant
body part to fully inform activity statistics
 Similarly separate CT body part examinations can be
post co-ordinated together to enable the multiple
examinations to be reported together as one report.
 The advantage is a more sophisticated approach to
audit, activity measurement and stocktaking

SNOMED CT
NCRS provides support for clinical coding using the
SNOMED CT nomenclature for diagnosis and procedure
codes.
SNOMED CT codes will be applied to the patients record
through manual selection by users, as well as an integrated
bi-product of clinical processes (i.e. orders, assessments).
SNOMED CT clinical coding is supported for inpatient and
outpatient encounters.
SNOMED CT
At the end of an episode / encounter of care, SNOMED CT
codes are recorded in NCRS via the Discharge Summary /
Encounter diagnosis and procedure codes.
The SNOMED codes recorded in NCRS are sent to the 3M
clinical encoder where clinical coding is completed in
SNOMED CT, ICD10, Read, and OPCS4.
Codes will be transferred back to NCRS and will update,
not replace, the patient diagnosis and procedure codes.
A full audit trail is available.
SNOMED CT
Within NCRS P1R2, users will have the ability to manually
record SNOMED CT codes within the following areas:
§
Discharge Summary / Encounter
§
Problems / Provisional Diagnoses
Within NCRS P1R2, SNOMED CT codes will be recorded
against the patients record, as a by-product of clinical
processes, in the following clinical areas:
§
Assessments
§
Findings / Flowsheets
§
§
Orders (viz. the code for the request)
Results (viz. the code for the procedure(s)
performed, not the radiological diagnosis or report which will
be transferred via HL7 messaging)
Orders and Results
in Radiology
SNOMED CT Order codes can be derived from Order/Entry
systems, but will be MUCH MORE ACCURATE if derived from
the accepted and if required modified final RIS procedure
entry with SNOMED CT matching.
SNOMED CT Results codes from Radiology are a dilemma.
This does not apply to ‘Procedure performed’ , but to a
provisional radiological diagnosis which may be a list of
differential diagnoses which could be entered by a reporter (ie
manually). Unlikely to happen given pressures of work!
The use of DICOM structured reporting may give the possibility
of automatically constructing radiological diagnosis codes from
the structured report
Structured reporting
DICOM SR – is an ‘envelope’, but within this useful structure is available.
User decides how much structure to use and controls with templates the type of
content, if it is mandatory or optional and modes of expression
Incorporated into the report are captured
images of key findings (which can be exploded
to full screen presentation), structured
diagnosis information, recorded audio, the
ability to sort findings by anatomy or priority, to
view prior findings associated with the
corresponding patient and hyperlinks to related
information.
