Five Reasons Why Medical Imaging is Ready for the Cloud
Healthcare enterprise organizations have been exercising caution with cloud adoption due to the regulated nature of the industry and desire to maximize return on existing (on-premises) IT investment. However, I am seeing accelerated adoption of SaaS (software-as-a-service) applications and expect this trend to continue.
In previous blogs (here and here), I’ve described some of Intel’s collaborative efforts with healthcare cloud providers working on medical imaging solutions. Let’s take a closer look at some of the key reasons why medical imaging lends itself especially well to the benefits enabled by cloud computing:
1. Exponential Growth of Imaging Data: The amount of data stored by healthcare organizations is doubling every 18-24 months, and in large part this is driven by medical imaging. As higher image resolutions are supported and richer media becomes more commonplace (e.g. video, 3D), the problem gets worse. Although medical images are rarely accessed more than a few months after they are captured, they are stored for many years to satisfy retention requirements, further increasing demand for storage capacity. The need to manage and scale the infrastructure to support medical imaging is putting significant time/cost pressure on Health-IT departments.
2. Loosely-Coupled Nature of PACS (Picture Archiving and Communication System): There are a lot of PACS vendors out there. Most EMR (electronic medical record) applications treat PACS as a loosely coupled system and have mechanisms to support integration with various solutions. Consuming PACS via the SaaS model will be much more straightforward and less disruptive to clinical end users than would be the case if PACS was tightly integrated with the EMR.
3. Pressure on Health-IT Departments to do More with Less: The healthcare industry is anything but static. Demands resulting from healthcare legislation & regulations coupled with trends such as BYOD (Bring your own device) are definitely keeping Health-IT departments busy. Evaluating applications against organization-defined criteria for SaaS suitability, and outsourcing where it makes sense to do so can enable IT to focus more time on strategic investment areas rather than “keeping the lights on”.
4. Need for Improved Access & Mobility: There is an increasing desire to access images anywhere, anytime, on any device in order to support a wide range of clinical workflows (e.g. diagnostic imaging on a workstation, reviewing an image with a patient on a mobile device at the point of care, etc.). SaaS applications are typically very mobile and support a wide range of client devices.
5. Technology Innovation: Several technology innovations have enabled medical imaging solutions to be delivered efficiently from the cloud. Virtualized, highly-scalable, servers and storage platforms enable large pools of computing resources that can be shared across applications. This reduces the solution cost (economies of scale) and improves agility (applications can respond automatically to fluctuations in demand). Converged networking solutions can manage network and storage traffic over the same unified fabric, reducing cables, complexity and cost. Improvements in server-side graphics capabilities enable images to be rendered in the cloud and streamed to client devices over low-bandwidth network connections.
Intel works closely with the software vendors, industry partners and organizations like the Open Data Center Alliance to ensure that our cloud solutions are scalable, secure, and meet the needs of the healthcare industry.
