It sounds like you are talking about a systems that covers all steps in a
hospital. GNUmed was never designed for that. I recommend you look at VA
Vista. You can write your own software for that but given how much ressources
it took to create GNUmed I doubt that you can write and maintain a software
that all users will be happy with. Each of the clients will call for special
features which take time to implement.
Nevertheless I can tell you what would be possible with GNUmed. Coding the
missing features is up to you mostly if you need them in a reasonable

This is standard operating procedure. A patient can have multiple numbers in
GNUmed, e.g. one for the lab software and one for the EMR. Patients are only
logically connected to one or more physicians. You can specifiy who has been
seeing a patient and who signs off on results but there is no way to limit a
patient to a certain physician and hide it from another.

From what I reason from this workflow I assume that right now all is done by
sending paper ?
For GNUmed they would simply input data in the patient's corresponding record
and the doctor could pull it up. Their is an inbox for the doctor where one
can see what new results there are.

There is only one database which gets accessed by the doctor in the office and
the care team in the hospital. Having multiple database would mean you will
need to write some sort of mechanism to send database records or exported
files from a to b.

Partly so. GNUmed can export and import records of various types. However you
would have to extend that to cover export and import to/from a common standard
such as HL7 records. For lab results have a look at MIrth. For the
communication aspect you could write an XMPP-based data transfer (think chat
client with file transfer). This is a completely seperate project and is
very ressource intensive (money or time).

I am not worried at all. You would have to implement end to end data
encryption and be HIPAA compliant.

I guess you are talking about logically and physically seperate networks and
databases in the hospital and the offices. If yes then you need the above.

That seems logical.

Umm. No. I mean I don't understand the above. For GNUmed you could open ten
GNUmed windows at the same time so you could be dealing with 10 patients
concurrently. Since this is access controlled by the database virtually
unlimited users could access the patient/record at the same time apart from
accessing/writing the same table row at the same time. This is postgresql. We
do not lock records or files. We lock only parts of a patient record.

Yeah that is covered by design. I would be interested what you find out on
this when you evaluate other EMR.

It is not only possible but alreaday there.

Scheduling has not been implemented short of using Korganizer for that. So
whatever you can do in Korganizer you can see in GNUmed. Everything else is up
to you. What you are talking about however is something different. It is order
mananagement and is often confused with scheduling. GE Centricity Carddas
(costs big money) is one such system.

Some scoring systems are implemented in GNUmed. You could add that one I am

You would have to see about that and extend any given EMR/EHR if neccessary.
There is quite a bit information out there on how to write a plugin for

Labs tend to have very special requirements and they mostly use special
software. What the lab needs is a lab information system (LIMS). I believe
there is even a software for that available. But that is outside the scope of
GNUmed and never will be in the scope. GNUmed simply accepts the results in
different formats and tries to make the most of it by displaying it. It will
never aid in the production (from e.g. blood samples) of these results.

You are talking about patient tracking and I guess you want some sort of time
tracking. Pulling up the chart from a scan of a wrist band can be implemented
(depending on the info of the wrist band) but if you are talking about time
tracking there are suddenly a whole lot more complex concepts. GNUmed operates
in terms of episodes. The minute a scan is done an episode could be started or
continued. An episode of an health issue. If you are interested you can read a
lot ant our wiki (http://wiki.gnumed.de - health issues, episodes)
For pulling up the notes plugin on the second scan we have a hooks system. A
hook can be defined to act on the scan-out event. But still this only emulates
the check in, check out stuff. It is not naturally supported and if you want
this you will have to check the hospital oriented EHR.

This is not supported and will be up to you to implement. GNUmed is targeted
at office settings not wards and stuff. You should be looking at VA Vista for

There is a progress notes plugin or you would habve to write your own.

See above. Given the work needed to implement #2 it is always wise to check
all EMR to see if maybe another one covers what you need already.

Outside the scope of GNUmed unless someone implements it. Again I am sure VA
Vista has this already.

Demographics is there.

Once you have evaluated your other options I would be glad if you could share
your findings on what works in what software and what does not.
