From AI-powered analytics to storing large data sets, cloud solutions enable hospitals to improve patient outcomes and streamline operations. by Listen Amid the surge of COVID-19 cases across the U.S. last year, Providence health system turned to data analytics in the cloud to better manage the onslaught of patients. Providence’s information systems and clinical analytics teams developed data analysis tools that gave its leaders real-time information on patient volume, hospital staffing levels and the supply of ventilators and personal protective equipment throughout its 52 hospitals across Alaska, California, Montana, New Mexico, Oregon, Texas and Washington. The Renton, Wash.-based organization also ran predictive analytics through Microsoft Azure to accurately forecast which hospitals would see spikes in coronavirus cases, allowing Providence to staff up and move ventilators and PPE to the locations that needed them most. “Because of the dynamic scalability of the Azure cloud, we were able to get critical data to our leaders so they could make decisions and provide the best possible care for our patients,” says Providence Chief Data Officer Brett MacLaren. Providers accelerated cloud adoption during the pandemic because it enabled them to quickly scale up their infrastructure to support patient care needs, including the increased demand for telehealth services, says Greg Caressi, global client leader and senior vice president of Frost & Sullivan ’s healthcare and life sciences team. “Cloud got a huge boost from COVID-19,” he says. But even before the pandemic, providers were already adopting cloud solutions. More than 50 percent of health IT workloads are currently deployed in the cloud, according to a recent Frost & Sullivan report. Managing and maintaining legacy systems can cost up to 64 percent of IT budgets, so many organizations, particularly in healthcare, can’t afford to do everything on-premises anymore, says Mutaz Shegewi, IDC’s research director for provider IT transformation strategies. “It’s mostly to modernize IT infrastructure and to facilitate digital transformation,” he says of cloud adoption. Cloud solutions can also help reduce costs, break down data silos and improve data access across an organization or multiple stakeholders. For example, hospitals involved in a merger or acquisition can use the cloud to standardize their technologies and help integrate different aspects of their operations, Shegewi says. Real-Time Data Improves Care Providence, a nonprofit healthcare system, partnered with Microsoft in mid-2019 to modernize its IT infrastructure with Azure cloud services. When widespread pandemic restrictions hit in March 2020, Providence was in the midst of building a data lake and data warehouse in Azure by replicating data from its electronic health records, supply chain and other applications from its data centers. Early in the pandemic, Providence tried to perform data analytics with its in-house data warehouse, but its servers couldn’t consistently handle the compute-intensive task simultaneously with daily data processing needs, so the organization quickly pivoted to Azure to power the effort, MacLaren says. “We were hitting capacity constraints, so we felt this was a good first use case for the cloud,” he says. Providence uses several Azure products and services, including Azure Data Lake Storage Gen2 for storage, Azure Databricks for analytics and machine learning, and Power BI to produce real-time reports on dashboards. The goals during the pandemic were to prevent hospital overcrowding and to forecast and anticipate staffing, PPE and ventilator needs across its hospitals, MacLaren says. “The dashboards allowed our frontline caregivers and regional leaders to make critical decisions,” he says. “For example, if a hospital is full, could we divert incoming patients to other nearby facilities? Do we need to move ventilators to another part of the state that was hit harder? And where do we need additional doctors to treat patients?” Dashboard use has waxed and waned over the past year, depending on infection rates, MacLaren says. But real-time data streaming is just one use of the new cloud data platform. MacLaren is planning other data projects, including improving patient flow within hospitals, implementing cloud-based image archiving and deploying artificial intelligence to analyze medical images to detect diseases early. “We are at the tip of the iceberg in unlocking the capabilities that the cloud enables,” he says. The Benefits of AI-Powered Diagnostics Researchers at UC San Diego Health in California developed a machine learning algorithm that analyzes chest X-rays and detects pneumonia associated with COVID-19 infections. When pandemic cases soared in the spring of 2020, the university deployed the machine learning model on Amazon Web Services (AWS) under an approved experimental protocol to assist its experts with diagnosis. The algorithm overlays X-rays with color-coded maps that show the probability of pneumonia. “When a patient comes in, the emergency room doctor may order an X-ray, and the AI results pop up next to the X-ray film within a few minutes,” says Dr. Albert Hsiao, a radiologist and associate professor at UC San Diego who developed the algorithm with his research team. Physicians at UCSD Health’s emergency department need to make fast decisions on patient care, so they often have to review X-rays before radiologists can weigh in. The AI analysis helps support these decisions, Hsiao says. “It’s ultimately the physicians’ interpretation of the X-ray and color map that matters. They can ignore it if they think the AI is making a mistake. But occasionally, the AI picks up something that would have been ignored, and it allows the physicians to look more closely,” he says. The algorithm has analyzed about 100,000 chest X-rays since last year, which is nearly all the chest X-rays performed at UCSD Health. 63% The Hybrid Cloud Makes Data Management Easier Luminis Health in Maryland is taking a hybrid cloud approach. It operates a private cloud using Nutanix hyperconverged infrastructure, but two years ago, the organization began adopting public cloud services where it made strategic sense, says Associate CIO Ron Nolte. The system has adopted Microsoft 365 for email and office productivity. When it was time to upgrade its in-house Oracle enterprise resource planning software, it migrated to Oracle Cloud Infrastructure instead. Luminis Health is also deploying a cloud-based image archiving solution from a provider that will store the images in Google Cloud Platform. The organization is not cloud-first, but its IT leaders say they consider cloud options when it’s time to upgrade or purchase new applications. “It’s picking the right tool for the right job,” says Juan Rodriguez, IT director of Luminis. “Where it makes sense, we will move a solution from on-premises to the cloud.”
