Hi! This is Sonja from B2i Healthcare.
In the previous videos of this series
we focused exclusively on the Local Code Systems themselves.
However, you are probably interested in how these local codes can
be used in conjunction with other terminologies.
This is why I will talk today about using local codes
in value sets and mappings sets.
A value set, and there's an example of one here that I downloaded from the National Library of Medicine's
Value Set Authority Center called "Below Normal Follow up"
A value set is simply
a collection of concepts as you can see here.
It can contain members from a single terminology
or like here, from multiple terminologies.
We have for example ICD-10
ICD-9, SNOMED CT and so on.
Local codes can be members of value sets
and for this reason I already created a value set here
and added several SNOMED CT concepts and now
I would like to add some local codes
There are different ways of doing this:
the easiest is to simply grab a local code in the view
and just drag it over into your value set.
That works if you just want to pick them and then
drag them over.
You can also add a whole part of the hierarchy,
a code and all the sub-codes. If you right-click it
and then you use "Add concept and descendants
to active value set" but since I already
added these I don't want to do this.
A third option would be to use the search.
I could look for example
for "Managers" and search.
The search results are down here in the view
and I click CMD+A
or CTRL+A for Windows to select
all of the results and then you can just simply
drag them into the value set.
Once you are done, you just save it
and enter a comment
and now we've added local codes to the value set.
If you want to open the editor for one of the members,
you can do this just by double-clicking.
So this is the editor for the "Traditional Chinese medicine physician" code
and you already know the overview tab
and there's a value domain membership tab
which shows if this local code is part of a value domain.
You can see the name of the value domain here, you can see that the
membership is active
and that it hasn't been published yet.
This button here will display
inactive members and you can see that this
is also a member of the "Language" value domain
and that this membership is inactive.
So much about value sets now let's move to mapping sets.
This is the value set perspective
and this is the mapping set perspective.
Let's click it and close
these editors.
Mapping sets are organized here in this view. You can see that I have already
two mapping sets in here. Let's open the one called "Occupations".
You see it's an empty sheet
because in mapping sets you can use
any terminology or classification system
as a source which would be in this part of the sheet
or as a target which would be
on the right side.
Today I will map local codes as a source
and SNOMED CT concepts
as a target. However,
I could also map local codes to other standards for example to ATC
or LOINC, even within the same mapping set. So there are no restrictions.
To start the mapping
let's drag a code, maybe
"Building architect", into the mapping set
You see that it's on the left side now
and it's mapped as the source term.
Now we need to find a target.
Let's look for building architect. Here it is.
I just move it over here wait until it's highlighted
in then I drop it.
Let's try another one, for example "Restaurant manager":
I just move it over and
then I can look for the target,
here's a restaurant manager, and again I just move it over,
wait until it's highlighted and drop and so on.
You can also move are several codes
just in like this and then
map afterwards.
If you want to remove a mapping, you just right-click it
and go to "Remove selected mapping" or you can also just use the Delete button on your keyboard
to do this.
Once you are done, just save
the mapping set and here it is.
The mapping is also
referenced on the tab. So for example
if open arm the local code editor
for "Restaurant manager" and
go to the Mappings tab I can see now
the mapping that I just did. I can see the name of mapping set,
the referenced component,
which is a local code, and the map target, that this mapping is active,
and that it's not been published yet.
If you curious to see what the map target or
source is you can just right-click it and then there's
the option to open the editor. I could open the
mapping source editor which would opened editor of the
Restaurant manager, but we have this already open, so I won't do this.
But I can also open the editor of the target which would be
the editor of the SNOMED CT concept. We can see all the information about
this concept here.
If you're curious about where it's located within the hierarchy
you can use "Reveal mapping target in navigator"
the navigator" or in the view as we call it,
and open the navigator and then you can see where "Restaurant manager" is.
This works also for
the source, which is here.
One last word about
local codes that are referenced
in a mapping set or in a value set.
We have kind of security mechanism that prevents you
from I'm deleting codes that are referenced somewhere.
If I tried to delete "Restaurant manager"
I could not do this untill
I removed all the references so you would have to
delete the reference first in the mapping set
or in the value set before you can actually delete this code.
That's all I wanted to show for it today.
In the next video I will demonstrate
importing and exporting local code systems.
Thank you very much for your attention. Bye bye.
