Although people are the same everywhere, and diseases vary a bit between regions, medical software is country specific.
4 areas
1 Accounting and practice management. Each country has its own laws so accounting and tax vary in each country, and tax is changed each year, also each country has different health subsidies, insurance, and payments system. Medicare has 10s of thousands of item numbers and then there are private insurance rebates for these items as well, and they are unique to Australia, and are varied each year.


2 Lookup data used by Doctors. Each country has different allowed drugs, as regulatory bodies may not have allowed a drug, or have restricted it, or the government may restrict its subsidy, or the pharmaceutical company may not market in that country. this information changes regularly, in book form a new book each month. Various textbooks in electronic form, which are used from other countries, and vary every few years when a new edition comes out.

3 Recall and reminder systems for PAP smears, vaccinations, and to make sure abnormal results are seen and patients are recalled, and that it actually happens.

4 Actual notes written by the Doctor about an individual patient, and correspondence about that patience. This is the loose leaf folder on an individual patient that your doctor has. Currently only about 50% or less of doctors use electronic medical record. They are no faster and often slower than paper based systems. Hospitals are moving to electronic systems, but the primary medical record is still paper based. 1 hospital I work at, every time you hear thunder you know the network is down. Servers elsewhere, dodgy microwave link, no electronic ordering of tests or viewing of results, no writing of letters until the weather stabilises. Pen and paper still works, but old paper records get locked in some remote dungeon and later pulped after a relatively short period, ?3-4 years from last attendance. All hospitals in NSW are being moved onto the one electronic system that is slow and cumbersome for end users, poorly supported, and now will lock that company in as the only providor in NSW, as no competitor has local experience.

What Doctors are paying for is the regular updates that incorporate the changes in all these external data that occur in a timely manner. One way they pay is by having the software subsidised by drug company advertising in the software in front of them on the cheaper system.

An open data format would be good for financial records and patient information. An open source solution would need to be implemented and maintained in each country. this will be difficult for a small volunteer community and require they active involvement of a support company in that country.

The purchasers will pay for a good solution, but most would want to see a working example, and hear about one from a buddy. There are plenty of conferences that can be used to showcase a good working example with a good support company, but till there is an imputus to change, like their current system breaks, there will be slow uptake.

Exporting patient files, with the patients details (name, DOB, sex,
Medicare number, etc.) from HCN's software is possible as they can be
exported from the program as a delimited text file (patients.out), but
the patient's billing history, etc. cannot be imported into another
medical practice suite and the database isn't accessible without HCN's
access (logged in with a valid logon).


to me it sounds like what is needed is to transform the exported file into
an XML schema which, if done in a meaningful way, could be fairly
easily transformed into any desired format - that is, there's probably only
a certain amount of different information types to worry about, and each
type could be captured with appropriate markup and class definitions.. then
it could be imported and/or exported into any db schema with
a standardised parser


Now, this type of software is the perfect candidate to be on an open
platform (which some medical practices use Linux to store a flat-file
database on), and with simple google seaches I've found some
open-source Medical Billing/Appointment book practice management
suites, but they were all on 0.x releases and unsuitable for the
Australian medical billing system, with no mention to Medicare. Has
anyone found anything for Australia; I'd be interested in following
the development for a Linux/multiplatform open-source practice
management suite suited to Australia's medical/Medicare standards.


I completely agree, and would even go further to day that it is exactly this
kind of information that needs to be freed.. but in terms of the software
itself, I imagine that this sector is in a particularly lucrative market
place. What I mean to say is that given the international climate around
medical data (well, ok, the USA's medical system), the goodness and badness
of software can really be established in how usable it is for professionals
who are anything but IT focused, and in fact are more properly focused on
the job at hand - namely, curing illness. If the information is published in
open formats, the software itself can compete in each of the localised
markets, given the particular laws that are applicable in different
countries and different states that may effect various aspects of the
system,  and there's nothing wrong with that, but what is important, and I
mean *really* is important (and I definitely feel in this circumstance more
than others), is that transportability of the information itself. An open
source product can compete in the market as with any other vendor, and I
think many here would advocate such a solution, but really I think it's an
open data format that should be higher on the list of priorities for medical
information.. this would, needless to say, provide possibilities of exchange
between different hospitals and GP practices that can be vendor neutral, and
can evaluate the effectiveness of software on it's functional merits rather
than the ability of a licensing model to lock in an entire industry to a
single solution with extortionate fees.

An open source model for the software may benefit from this environment with
a properly thought out, probably OO design, but software companies with more
focused resources may or may not be able to be more effective in that space,
but when it comes to the medical industry's priorities, a focus on patient
care, I think, far outways whether some software is GPL'ed or not, as long
as the data is available and useable for all those that need to, whether
they can afford a particular vendor's fees or not.

Pushing such a thing wouldn't be easy, but I think it would be an effort
that ultimately would be more fruitful than the advocacy of a particular
open source solution in favour of another propriety solution that has the
commercial an support resources available to appeal to an industry that
would see IT as support and not as core to the business.

This doesn't really help you, but I think this sort of information is a
prime example of where freedom is very, very important
