For many patients, I have aliases declared for different names. This
is typically used when a woman gets married and changes her name. It
has always worked fine to look up their name either way.
Except that has stopped working, I'm not sure when. I look at the
patient record, and the aliases are still there. So I am assuming
that one of the cross references has been messed up somehow.
When I look at field 1 (ALIAS) in the PATIENT file, I find that the
.01 field (ALIAS) has two cross references: ANAM201, which is MUMPS
type index which the descriptions states has a purpose of keeping the
name components in sync. This doesn't seem like it would be used for
lookup.
Then, there is a "B" index of type MNEMONIC. This seem like it would
be more for the use I am looking for. But I can't tell for sure if
this is a "B" index for the subfile, or for the entire PATIENT file.
This is it's set node:
S:'$D(^DPT("B",$E(X,1,30),DA(1),DA)) ^(DA)=1
So, to me, this looks like it is affecting the "B" index of the entire
file, and inserting the alias name into the "B" index.
So I look in ^DPT("B",AliasName), and I don't find my entry. This may
explain why it's not working.
I wonder if the lookup in CPRS is not more sophisticated than a simply
fileman lookup. This is because CPRS will add the words ALIAS after a
patient name in the lookup box when appropriate. Either there is
another way that aliases are looked up, or it does a standard fileman
lookup, then compares the record to see if it was found by the name or
whether one of the aliases match.
Anyway, does anyone have any ideas how to get the "B" index recreated
properly? If I just reindex the file in fileman, I don't think that
the aliases will be added. And come to think of it, maybe this is
what I did at some point to break it in the first place. I am able to
write code to do this manually, but I wonder if there is another way
that this "should" be done.
Thanks
