Healthcare is likely one of the most data-rich industries, however because of strict privateness and safety legal guidelines, information scientists haven’t been in a position to do a lot with it. However now, because of the confluence of a robust safety setup within the cloud and using privacy-preserving strategies for analytics, Windfall Well being is beginning to take {the handcuffs} off its information scientists and unleash innovation on massive medical information.
With 52 hospitals, greater than 1,000 clinics, and about 120,000 workers, Windfall Well being and Providers is likely one of the largest healthcare teams within the nation. Like most healthcare firms, Windfall Well being takes steps to keep up the integrity of its sufferers’ information. In any case, no one needs to be fall afoul of HIPAA, which carries fines as much as $50,000 per violation.
That safety focus was high of thoughts because the Renton, Washington firm got down to renovate its information analytics structure, beginning with a migration of an getting older SQL Server information warehouse into its Microsoft Azure cloud. As the corporate labored with Databricks and others to arrange the brand new information surroundings in late 2019, it took further precautions to make sure that tight management was maintained over the information, stated Lindsay Mico, Windfall’s director of knowledge science.
“Windfall units a uniquely excessive bar for what a safe cloud seems like,” Mico stated. “Each tech firm that I work with….has a mindset that that is what a safe cloud seems like. After which they begin working with us, they usually’re shortly disabused of the place that bar is about.”
For starters, plain vanilla community configurations in Azure wouldn’t suffice. Public IP addresses could also be normal fare for out-of-the-box Azure deployments, however that might not be accepted in Windfall’s Azure deployment, Mico says. Making certain solely non-public IP addresses had been used required controlling the Azure Digital Community (VNet) at a low degree, he stated.

“We labored hand in hand with Microsoft and with Databricks to craft new deployment architectures that allowed us to correctly safeguard affected person information,” Mico advised Datanami in an interview at Databricks’ Knowledge + AI Summit in San Francisco earlier this summer time. “We wanted one thing that was closed off from the general public Web.”
Snowflake was additionally concerned in Windfall’s new cloud-based information structure. The preliminary undertaking was migrating the getting older SQL Server warehouse into the Snowflake information warehouse, which would offer a extra scalable system for analyzing enterprise and scientific information. (Windfall is sufficiently big that it could accommodate customers on a number of information warehouses, so Databricks and Snowflake environments exist independently.)
Value management was an enormous preliminary use case for Windfall’s new cloud warehouse, that are used for conventional analytics in addition to constructing and operating machine studying fashions. As a not-for-profit Catholic hospital with a said mission to assist the poor and the needy, Windfall has an obligation to ship reasonably priced care, and analytics might help in that regard, Mico stated.
“We additionally know healthcare has a price bubble. Prices maintain going up for sufferers. Healthcare methods are on extraordinarily skinny margins. It’s a lose-lose,” he stated. “So discovering methods to make use of information and analytics to regulate price–it’s existential for healthcare typically.”’
A few of the preliminary use instances concerned utilizing machine studying fashions to forecast affected person demand, together with issues like acuity and size of keep. These predictions are fed right into a staffing mannequin that tells Windfall what it’s staffing calls for will seemingly seem like over the following two months.
The limitless elasticity within the cloud is an enormous improve over what the corporate used earlier than, Mico stated. “Once I joined Windfall, we ran fashions on computer systems below desks,” he says. “I couldn’t match a mid-size boosting mannequin. That might crash our Cloudera cluster recurrently. These drawback are solved.”
Whereas the information warehouse migration began earlier than the COVID-19 pandemic, Mico and his staff did a lot of the work in the course of the pandemic. The healthcare firm leveraged a number of out-of-the-box machine studying fashions that got here with its digital medical information (EMR) software program from Epic Methods, which labored effectively, Mico stated. As the biggest Epic person, the success of the machine studying fashions bodes effectively for Epic’s R&D staff.

If there was a silver lining to COVID-19, it was that it accelerated the deployment of next-gen methods, together with telehealth, which Windfall was already investing in, Mico stated.
“I believe it was serendipity, in a method,” he stated. “We had ready. We had a very sturdy infrastructure in place to deal with telehealth. We had been in a position to transfer big volumes to telehealth. It additionally gave a lift to predictive analytics. We deployed a lot of fashions round mortality danger, ICU size of keep, and some others within the early days of the pandemic. These had been functions that had been constructed into Epic. It’s simply the primary few steps of a very lengthy journey. Ther’s a lot extra alternative for AI to enhance scientific care.”
As an example, the corporate is operating some real-time analytics on Well being Degree Seven (HL7) medical paperwork that originating in Epic. Windfall is utilizing Spark Streaming to course of that information earlier than it’s loaded in actual time into Delta Tables on the Databricks warehouse, Mico stated.
“That work began as an effort to construct what we name a mission management middle, an actual time view of what’s occurring within the hospitals,” he stated.
One of many early use instances for the mission management middle is to achieve visibility into a person hospitals useful resource to find out whether or not it could deal with an incoming affected person. It is a great tool to assist stop hospital overcrowding, which was a really actual menace throughout the peak of COVID-19.
Windfall makes use of analytics and AI for enhancing enterprise and scientific operations
“[It’s] a very good start line, however you may see that upon getting an actual time view into what’s occurring with a healthcare system – who’s there, what do you want, and relating again to their chart — you may then begin predicting what’s coming subsequent,” he stated. “You can begin optimizing choices about scientific care or about operations. So I’m fairly jazzed about mission management.”
Such methods will not be put into place with out quite a lot of forethought. Mico is one in every of a handful of people that sit on Windfall Well being’s predictive analytics steering committee, which makes choices about what forms of predictive methods must be deployed.
The corporate is taking a look at leveraging some extra highly effective AI applied sciences, together with deep studying, to additional optimize its operations and enhance medical care. Particularly, it’s working with John Snow Labs and its Spark NLP fashions to have the ability to extract significant information out of physician’s notes.
Safety and privateness are paramount when coping with this degree of delicate information, so the primary order of enterprise with Spark NLP is the de-identification of physician’s notes about sufferers. The healthcare firm is utilizing pretrained fashions from John Snow Labs that may spot identifiers like dates, names, addresses, and ZIP Codes.
“It really works surprisingly effectively, even simply out of the field,” stated Nadaa Taiyab, a senior information scientist with Tegria, a expertise and companies firm owned by Windfall.
After tagging the identifiers, Windfall then obfuscated the information by changing it with dummy information, thereby de-risking the non-public well being info (PHI). This course of allows Windfall to make use of the aggregated medical information for superior analytics and coaching machine studying fashions.
Whereas the obfuscation step reduces the danger of PHI falling into the incorrect palms, there are occasions when actual affected person information is important, particularly when utilizing machine studying fashions, Taiyab stated.
“If you happen to combination it, you may’t use it for machine studying, in the event you’re attempting to foretell one thing at a affected person degree,” Taiyab stated. “If you wish to predict it at a bunch degree, that’s one factor. However it is advisable to have patient-level information” for patient-level predictions.

Windfall can be ready to make use of its affected person information to additional medical analysis by the Institute for Methods Biology (ISB), a Seattle, Washington medical analytics agency based by Dr. Leroy Hood, one of many researchers within the Human Genome Challenge. The info safety work achieved by Windfall has allow it to share information with ISB, which Windfall acquired in 2016.
In response to Mico, ISB’s capacity to mine Windfall’s massive repository of medical information has been vital for ISB’s analysis into well being situations, akin to lengthy COVID-19. “That’s simply an instance of what it means while you’re in a position to stage and combine information in a safe cloud surroundings,” he stated.
The funding in constructing a safe cloud information structure hopefully can pay dividends as Windfall explores extra methods of utilizing superior analytics and AI to enhance its healthcare mission.
“Windfall has provide you with a blueprint for what a safe cloud for healthcare seems like,” Mico stated. “It’s taken quite a lot of reperch, quite a lot of studying, quite a lot of collaboration with our companions. And we enhance it at each step of the way in which. Our deployment fashions change as we be taught new issues. However we expect we have now a really sturdy safe blueprint for it.”
On the finish of the day, we’re barely scratching the floor of what superior analytics and AI can do for healthcare. Entry to information stays one of many major roadblocks to progress on this regard. The work that Windfall has achieved to mitigate the safety and privateness dangers is an efficient first step, however there far more work to do.
Mico recounted how he attended an AI drugs convention in San Francisco in 2021. “Each startup stated the identical factor,” he stated. “If we simply have the information, we may construct essentially the most wonderful stuff.”
