WHY SNOMED CT?

Electronic Patient Records

Quality Healthcare requires effective
communications

Effective communications need a
common language and a common
structure for humans AND for computers

SNOMED CT allows clinical data to be
recorded in a human recognisable and a
computer recognisable way

With an agreed structure, data can be passed from one
system to another but only if we use structured records
and a structured terminology

Synonyms

for different
expressions

meaning

Terminology / Classification


are used to populate a computerised
patient record (EPR) and describe
concepts related to
individuals

and can
support the clinical decision making
process

Terminologies


categorise concepts usually relating to
populations

or
groups
of patients and
support business planning and
epidemiology purposes

Classifications

Classifications are intended for population
statistics and analysis.


Terminologies are
designed to be used by clinicians in their
recording of data in a patient record.

Maps between SNOMED CT and the
classifications are provided as part of the
national product set to support classification
coding.

Subsets

What is a SUBSET?


SNOMED CT is extensive


it is supporting a
common vocabulary for all healthcare
specialisms
,
and all healthcare professionals, as well as
keeping up to date with current practice


A subset is ‘smaller set of SNOMED CT ‘ that
meets a particular requirement


A SNOMED CT subset can be a group of
concepts, descriptions or relationships chosen for
relevance under certain conditions or in certain
contexts

Subsets

Why SUBSETS?


It is often desirable to constrain the SNOMED
CT concepts available to a subset, say to help
faster data entry


so for example, all possible
performed procedures in a radiology department
or a theatre department


Subsets

HOW APPLICATIONS USE SUBSETS



Supports easier navigation


Can be used to limit to specific SNOMED
CT codes


Can act like a ‘favourites’ for the end user


Can be used nationally or locally

synchronised national releases


Access to subsets may be role based

Current Subsets Examples

Allergens

Diagnosis

Laterality

procedures

EXAMPLES OF USE AND
BENEFITS

The World Changes…


Changing demographics, increasing requirements


Wider range of drugs


Greater understanding of medical conditions

Systems need to
support


People use the internet to research


Peoples expectations with regard to knowledge and
care have changed

Changing
behaviour

Summary Care Record


Patient summary record


Contains allergies, adverse reactions,
medications (current repeat, discontinued
repeat, acute). Additional information with
patients consent such as current diagnoses

e.g. diabetes, asthma


This SCR clinical data is stored using
SNOMED CT


Provides consistent recording and semantic
interoperability across a mixed coding domain


Patient makes choice of provider with
information support

GP and patient decide that referral
is appropriate, and creates
appointment request

GP produces referral letter as template or dictation

Consultant reviews and
accepts referral

Appt. booked by the patient via internet or phone,
or in the practice
