Cloud PACS connected to your practice system: when it pays off
An image archive of your own is thought of as a radiology matter. For a practice with one X-ray unit or an ultrasound the calculation is different — and it does not always come out in favour.
A practice that produces images has some form of archive already. Often it is the device's own software, sometimes a network drive, occasionally both side by side. That works as long as nobody looks for an image from three years ago, and as long as the colleague who knows where everything is has not left.
The question is therefore rarely whether an archive is needed. It is whether an archive of your own, connected to the practice system, pays off against the makeshift arrangement that already exists.
What the connection actually changes
The difference between an archive and a connected archive is patient matching. Without a connection the patient is entered at the device, so typed a second time, with the typos that come with it. The same person then exists in two systems under two slightly different spellings, and a search finds them in one of the two.
With a connection the order comes from the practice system, the device takes the data over, and the finished image goes back with the same identifier. The gain is unspectacular and occurs with every single examination: no second entry, no name variants, and the report sits where the work happens anyway.
The calculation
Whether it pays hangs on a single number: how many examinations there are per week. The table below is not a price list but an order of magnitude for your own estimate.
| Examinations per week | What pays | Why |
|---|---|---|
| under 5 | stay with what you have | The time saved does not reach the running costs. A tidy network drive with a clear naming rule is enough. |
| 5 to 20 | look at the connection, archive optional | Almost all the gain is in patient matching, not in storage. Often connecting the existing system suffices. |
| over 20 | your own connected archive | From here, searching and matching costs more working time than running an archive. |
What speaks for the cloud and what against
In favour are the things a small practice would otherwise carry itself: backup, updates, a plan for outages, and reachability from outside when a prior image is needed on call.
Against it is dependence on the connection. Anyone loading images over a narrow line notices it immediately with large series. That is not a knock-out argument, but a point to measure before deciding rather than after.
Legally the same applies as to any service processing patient data: a data processing agreement under Art. 9 FADP is required, and it must be clear which law governs the provider.
An archive that does not talk to the practice system replaces one folder with another. The benefit sits in the connection, not in where the data is stored.
What to advise against
An archive acquired only because the device is new. Anyone doing fewer than five examinations a week gains nothing that outweighs the running costs, and takes on a contract in exchange.
And any solution without a clarified exit. Image data is the part of a practice that has to be kept longest; an archive you cannot get out of is a decision for ten years, not for a contract term.
