We have coded a number of documents in two seperate codes but have now decided that it would be better if two codes were combined into one code. Is there a way to merge the two codes into one? In the manual it talks about "grouping" referneces, but I don't think this is what we want to do, and I'm hesitant to automatically assign documents from the two codes to the new single code lest they disappear once we delete the original two codes. Also, the references have been coded under other codes and we don't want to loose that coding or spread it to all the included documents. How can we do this?

Hello Faye,

If you have a number of items assigned code 'A' and other items assigned code 'B' you can create a code 'C' and assign the new code 'C' to all of the items that have code 'A' and 'B'. Is that what you mean?

You would first need to create the code 'C'. It could be in the same codeset as 'A' and 'B' or it could be in a new codeset. That would depend on what your intentions are for the new code. Next you would list all of the items with code 'A', select all of those items (by clicking the checkbox as the top of the list of items) and then right click code 'C' (in the codes tab). When you right click the code you should see an option 'Assign selected items to this code'. Select this and all of your selected items will be assigned code 'C'.

Now do the same thing for code 'B' (i.e. assign code 'C' to all of the items with code 'B').

You now have code 'C' assigned to all of the items that have code 'A' and 'B'. Code 'A' and 'B' are still assigned to those items (so you have not lost anything) but you also have code 'C' assigned to them.

Best regards,

Jeff

Hi Jeff,

Thank you, that makes sense, but what if I now want to delete of code 'A' and code 'B'? Being that code 'C' was created on the basis that the articles were coded either 'A' or 'B', when I delete these two codes do they disappear from code 'C' as well?

Thank you,

Faye.

Hello Faye,

Each code is independant of other codes so removing a code from an item or deleting that code will not remove other codes from the item. I should make clear that I am referring to codes and not codesets. Codesets can contain many codes and deleting a codeset will remove all of its child codes.

In our example removing code A and/or B from an item will not remove code C.

If you are unsure about this you can alway create some test codes (in a test review) to see how it will work.

Best regards,

Jeff

Hi Jeff,

Good, that's what I thought but I wanted to make sure. Now I have one more related issue. I copied the coding and when I went to delete code A, it told me I would be deleting 4 items more than show up when I list both the included and excluded items for code A. Any idea where the missing 4 items may be? I don't want to miss coding them to code C before I delete code A.

 

Thank you,

Faye.

Hello Faye,

Without looking at those specific codes I am only able to suggest some reasons.

If you are only looking at the items that have the I (included) flag or the E (excluded) flag the extra 4 items might be items that have been marked as duplicates. Depending on when they were marked as duplicates or when they were coded, it could result in the discrepency

If you let me know which codes in your review match up with what you are calling codes A and C I can have a look at it.

Best regards,

Jeff

Hello Faye,

I just had a look at the 'Explicit palliative approach' code and there are 258 items with that code. Which code are you comparing it with to get the 4 items.

Best regards,

Jeff

Hi Jeff,

I just uncoded a few so now when I ask it to list everything with the code "Explicit palliative approach" it lists 256 items. Then when I click on the code in the tree and right click and select 'delete' I get a message that asks me if I'm sure I want to delete it because 261 items are assigned that code.....

Faye.

Hello Faye,

I understand what you are describing now.

The system is telling you that 261 items have been assigned that code but only 256 are shown when you list items with that code. What has happened is that 5 of the 261 items, after being coded, were marked as a duplicate. Once they are marked as a duplicate they will not be listed when you asked for items assigned a particular code.

The ID's of the 5 items and their master item are:

ID                Short title                     Master ID

2406396    Daher (2008)              2129334
2405255    Davidson (2002)        2407288
2129398    Ferrell (2007)              2130446
2130443    Ferrell (2010)              2129396
2130529    Gnaedinger (2008)    2129437

If you run a search on ID 2129334 and then go into that item you can see 2406396 is a duplicate of it (listed near the bottom of the screen).

This means that when you delete the 'Explicit palliative approach' code you are removing the code from 261 items but only 256 are visible to the user. The other 5 are duplicates.

Best regards,

Jeff
