PACS is dead. Long live PACS

It is my prediction that the days of the acronym "PACS" are numbered. Picture Archiving and Communications Systems are the hospital systems that store all those digital diagnostic images- X-ray, mammogram, MR, CT etc.

They need phenomenal storage capacity (Terabytes) and distributing those images (usually of the DICOM format) from the imagers to radiologists is therefore non-trivial.

When did you last hear an application based IT system have to define itself as a communication system? That's inherent in the fact that it is information technology. It feels illogical to make a big deal out of that, reflects challenges largely in the past and aspires to monolithic systems. I try and use the terms "DICOM Storage", "DICOM Viewer" and "Radiology Writer" to describe the constituent parts and apply as appropriate. Processes are being reengineered such that these elements are being reused in ways the inventing technologists hadn't imagined and the PACS term will itself be reengineered.

There's a lot of inertia in the acronym by virtue of the intellectual capital (deals, research papers, products, implementations) invested in it, so I don't expect a change any time soon... but watch this space

Google helps to Diagnose Patients

As a one time sufferer of the rare illness henoch schönlein purpura, I'm very familiar with the concern surrounding undiagnosed conditions. In my case it was the 80's and the efforts of a non-medically qualified, but very concerned, mother were more effective than the doctors in diagnosing an illness that aflicts just 14 people per 100,000.

So, I was very interested in how doctors are beginning to embrace the technology of the raging-consumer success that is Google. A British Medical Journal article reports on the success rate of search engines in helping unravel unusual and complex symptoms. Ironically, it is usually professionals that pioneer new technologies which subsequently filter into the high street and home. In this case it's been the reverse. Nevertheless, better late than never.

So, is this the end of doctors? Not really. Using Google, users successfully identified 58% of diseases published from a range of symptoms from The New England Journal of Medicine. It takes a qualified, intelligent human being to take that success rate beyond 80%. The computer is just doing what computers have always done well- to sift through huge amounts of knowledge (in this case pretty much the accumulated medical knowledge of the human race) and present it back in a prioritised fashion. You can't train a human to do that.
