Intro

Patient Merge is a complex piece of software. Be sure to read the manual. This will provider an overview of how to use it with WV.

Patient Merge Set-up

There are few WV-related issues with Patient Merge that first need to be resolved.

  • Due to various issues on how the MPI Parameters and the Local Site are set-up, the software may try to contact the MPI to resolve a merge, and fail to merge as a result.
  • Patch XT*7.3*113 takes away the ability for the local site to search the patient file for duplicates, and relegates that ability only to the Central MPI.
  • X-ref ALK3 in file 15 on the Merge Status field has a bug in it. A completed merge (Merge Status = Merged) does not delete the ALK index entry. Thus, the IHS patient lookup routine erroneously says that the patient is a potential duplicate patient even though the patient has been merged already. I am not sure where the bug lies (IHS patient lookup or the Patient Merge software), but the ALK x-ref documentation says it's supposed to be deleted when it's merged.

I created a patch to resolve these issues and you can find it here. This patch depends XT*7.3*113, as it fixes a change in that patch.
