Hear and Now: AI and Imaging, Your Data as Strategic Asset
Patient data is critically important to the continued development of artificial intelligence (AI). And the institutions that have this data should recognize it as a strategic asset, according Esteban Rubens, an IT infrastructure architect and executive at Pure Storage, a California company that develops flash data storage hardware and software.
Rubens is scheduled to speak about AI and imaging at the annual meeting of the Healthcare Information and Management Systems Society (HIMSS) in Orlando. He plans to explain why patient data is a strategic asset.
In the podcast, he said the prime message of this talk will be to “realize how valuable your data is … that you have to protect it … and that you have to use it.”
Why Providers Need To Value Their Data
The patient data at institutions uniquely reflects the patient population of the institution, Rubens said: “The population that you serve is yours. No one else has that same population.”
He noted that patient data accumulated over decades is particularly valuable. “If you are not using it now, somebody else — at some point — will,” he said. “We are not talking about some crass notion of monetizing your data. We are talking about algorithms that will directly impact your patient care.”
Rubens acknowledged in the ITN podcast that there has been “a lot of hype” around medical AI. But he stated that the hype is giving way to real progress. “We are way past the pure hype stage, because we have real things happening,” he said. “We are starting to see a lot of actual applications down to the clinical practice level of AI.”
Rubens describes himself as a “flash storage evangelist,” explaining that flash storage is a critical element to the infrastructure needed for medical AI to succeed: “Flash storage is the perfect complement” to the graphic processing units (GPUs) that drive AI applications. Flash storage “is massively parallel … has low latency and allows you to process huge amounts of data very, very quickly.” Its use, he said, “is the only way that you can be efficient in your AI work.”
Infrastructure: A Weak Link in Medical AI
Calling infrastructure “fundamental” to continued progress, Rubens explained in the podcast that without the proper infrastructure, latency could result — and that would be very bad for AI applications in medicine.
“People are already overworked and there are all sorts of issues with burnout. You can’t say that (an AI app) is really cool, but it is going to make things slower. The only way to ensure that adding more layers of technology won’t slow things down is to have the right infrastructure.”
Speed is extremely important — and configuring data centers properly is a key to it, he said. Putting all the data in a single place, such as a data center or data hub, will overcome what has been the Achilles heel of Medicine — data silos. This has been so not only because of the disparate locations where data is stored but because of the financial and logistical issues that surround doing so, for example, the need to maintain, upgrade and replace multiple sites and their data storage equipment.
“If you have a data hub, all the data lives in the same place as it really should,” he said. “All those logistical and financial issues get smoothed over because everything is in the same place.”
Just as configuring infrastructure efficiently will support the expansion of AI, so might the widening adoption of AI help in the evolution of medicine.
“There’s been a lot of really, really good work being done (in AI),” he said. “It is really about improving the lives of patients and physicians and other actors in healthcare.”
