Hi! This is Sonja from B2i Healthcare. This is the first video of a series about
working with Local Code Systems.
Besides the existing standards like
SNOMED CT, ATC or LOINC that we are supporting
Snow Owl allows developing and maintaining local and national code
systems.
Local Code Systems are internal identification schemes that consist of a
set of local codes and
their associated terms. This could be, for example, a list of
interface terms that are used in a clinical application.
Local codes can also be mapped
to other terminologies and referenced in value sets.
You can either create Local Code Systems
directly in Snow Owl or import them from an excel sheet.
I will demonstrate these features in later videos but
today I would like to show how Local Code Systems and codes are organized
in the Local Code Systems view,
what kind of information is displayed in
the editor and different ways
of searching for local codes. When working with Local Code Systems you
will use
this view. It works similar
to the views that we used to browse other terminology.
You can see that it has the same action buttons
up here as the other terminology views.
Local Code Systems
are organized in folders that can be
expanded and collapsed by clicking at the triangles
or up by using these buttons here and
the local codes are indicated by the green icon, by the circle with the C
so these are all local codes while
the Local Code Systems
have this icon so you can see that
I imported two Local Court Systems in Snow Owl.
They can be
comprised either of a flatlist of codes like
the first one here or they can be a
hierarchy like this one.
The level of detail is not limited
so depending on your needs more sub-codes
can be added, hierarchy can go as deep
as you wish. Double clicking an item
in the view opens the editor
so if I click, I double-click on a code,
it opens the editor for
the local code, while if I click on the folder here,
it will display
the editor for Local Code System which looks
different from this one.
There's also the option to link your
editor to the view which is this button.
If I press it, then it's link
now you see it's indented and
if I open several local codes
and then click on the tab I can see
where the local code is located
within the hierarchy and I can also see which
Local Code System it belongs to.
Their is also this view down here
for the parents which goes up in the hierarchy so you can see
higher level codes, for example, if I click on "restaurant manager" I can see
that the next level
would be Food and Beverages Services Manager
and if I open it and click even one higher, you can see
that is then the Local Code System
itself. Now let's take a look at
the editor for Local Code Systems.
The information here is pretty much self-explanatory
there's a name, a short name which is also used as the display
in the list, there is a unique
identifier for the Local Code System
a version, description and two optional fields for the maintaining organization
and you can add comments in this field here.
The editor for local codes looks like this.
There is a unique identifier.
This can be digits or letters or any combination of
the associated term and
any number of alternative terms can be added here so
for example, this one has two
alternative terms. We can also see if the code is
active or inactive and if it's published.
This one hasn't been published yet.
If it has been published, the effective date is
displayed here.
Searching for local codes work similarly to searching in other sources.
The view has a filter where you can
type in your search term, for example, "manager"
if I do this, it shows all the local codes with the term
"manager" and also the Local Code System that it belongs to. You can also
search
for a name of a Local Code System here.
We also have a comprehensive search
across all resources which is the quick search. This is this
text field up here. If I type in a term,
it will not only show Local Code Systems but also
SNOMED CT, ICD-10, ATC and so on
and in this section there is the local
code that has the term
"food" and the short name of the
code system in brackets.
You can also search for an ID,
for example, this one
we'll return the code that has this ID
and if you mark it and click it, it opens
the editor of this local code.
If you want to specify your search criteria you should use the advanced
search.
This is this button here. You can base
your search on a number of different criteria
so you'd always have to check this box first and then
enter the term, your search term
so you can search for code term, alternative term
active or inactive codes, you can specify an effective time
for example, a time range or you can just look for unpublished codes
and you can combine
all the different criteria by clicking this all.
You can also use
wide cards or operator, for example, if I look for "manager
but not restaurant"
I would have this and then click "search"
and the results are displayed down here in the search view
so there's "catering manager" so there's not
the restaurant manager, it is not part of this search
and if you want to see the editor you just double click it.
This opens the editor and then you can see more information or make
changes to it. In the next video
we will create and modify a local codes and Local Code Systems.
Until then thanks for your attention. I hope you enjoyed
this short introductory video. Bye-bye.
