Hi all,
while preparing some documents for the 2nd generation Care2x, I remembered the initial idea of a global PID. This should be an ID for a person which must be unique globally.
Does anyone know of any work on this, proposals, thesis, dissertations, or working protocols? I would be glad to know the links to the documents. Please let me know.
About the PID concept, also named MPI, the following was taken from the openhealth list:
"State of the art may be in the eye of the beholder, but we have a component out of which an MPI can be built. It is an implementation of the Person Identification Service (PIDS) specification of the OMG. This includes patient correlation management, merging, etc. It is available at http://OpenEMed.org as part of the OpenEMed software suite. It has a FreeBSD style license. It should fit into your J2EE environment quite well although it has no dependencies on J2EE.
It supports almost any kind of database underneath it and can work in a fully distributed environment with security."
Anyway, I noticed the VISA credit card system and its numbering system.
I bet you were inspired by: http://www.mail-archive.com/openhealth-list%40minoru-development.com/msg10711.html and http://www.mail-archive.com/openhealth-list%40minoru-development.com/msg10713.html
Well... it was described a few years ago and at that time it was not considered such a clever idea.
But if you still want to go that way, first take a look at "Anatomy of Credit Card Numbers" that you may find at: http://www.merriampark.com/anatomycc.htm
Also, as VISA credit card system uses a variation of the "High-low strategy" referred in page 11, point 5. of the "Data Modeling.pdf" file that I attached to the 29Feb2004 email on the subject:"We need help from the previous designers of the Care DATABASE".
Lets say the first 4-digit group is exclusively for coding the country where
It seems that VISA, among other tests also tried that and it showed to be not practical.
the person was first registered. Should we use an ISO country numbering?
The first law of open source says:
"In face of a new problem try first to search and reuse an already made and proofed solution"
If that fails then, and only then, reinvent the wheel yourself... :-)
If VISA can do it for global credit system, why couldn't we for the healthcare system?
Well, they do have to deal with country specific idiosyncrasies at identifying patients, do they?
Time for Care2x foundation to come?
It is always time for that...
