About The Customer
Nuffield Health is a UK-based healthcare organization with no shareholders, investing all of its income back into its vision to build a healthier nation. It does this through outstanding day-to-day services in its family of 31 award-winning hospitals, 112 fitness and wellbeing clubs, health care clinics, and more than 200 workplace wellbeing services, and through its flagship programmes to support communities by widening access. The organization has been working for 60 years to make the United Kingdom fitter, healthier, happier, and stronger, all for the public benefit. It has a user count of 22,000 and uses Zscaler Internet Access™.
The Challenge
In 2015, Nuffield Health, a UK-based healthcare organization, was preparing to undertake several projects aimed at improving productivity, efficiency, and patient services, while enhancing user experience across its corporate office, hospitals, and gyms. These projects included a migration to Microsoft Office 365 and the introduction of TrakCare, a new electronic health record application. However, the success of these projects was heavily dependent on the performance of Nuffield Health's network, which needed to secure sensitive patient and personal data flowing in and out of its facilities. At the time, Nuffield Health had only one MPLS network link running at 30 MB at each of its sites, which was insufficient for the upcoming projects and the required resiliency. Furthermore, 60% of its traffic was already destined for the internet rather than its data centers, a percentage that would increase significantly once Office 365 was deployed. The team realized that it needed more bandwidth and more resiliency in its network, and it needed to consider the cost and latency resulting from backhauling all that traffic through the data center. It also had to determine the best way to secure all that internet-bound traffic.
The Solution
Nuffield Health began researching options and designing its new network, and eventually decided on an SD-WAN solution from Silver Peak. Investing in SD-WAN provided much more room for innovation and flexibility. However, with traffic going direct to the internet and not going through the data center, security became a major concern. Given the number of sites that Nuffield Health is responsible for and with the amount of traffic it expected to be destined for the internet, a cloud security solution made the most sense. Nuffield Health was looking for a solution that could not only protect its critical patient data, but also easily integrate with its SD-WAN deployment. Nuffield Health selected the Zscaler Internet Access service, which examines the Nuffield traffic destined for the internet over all ports and protocols, including SSL-encrypted traffic. It also enables policies to follow users, regardless of location or device, providing security for Nuffield’s 16,000 staff around the UK and an additional 6,000 medical consultants. Nuffield Health also counts on Zscaler cloud-delivered security to protect data coming from its 31 hospitals and 112 fitness clubs.

Hospital Inventory Management
The hospital supply chain team is responsible for ensuring that the right medical supplies are readily available to clinicians when and where needed, and to do so in the most efficient manner possible. However, many of the systems and processes in use at the cancer center for supply chain management were not best suited to support these goals. Barcoding technology, a commonly used method for inventory management of medical supplies, is labor intensive, time consuming, does not provide real-time visibility into inventory levels and can be prone to error. Consequently, the lack of accurate and real-time visibility into inventory levels across multiple supply rooms in multiple hospital facilities creates additional inefficiency in the system causing over-ordering, hoarding, and wasted supplies. Other sources of waste and cost were also identified as candidates for improvement. Existing systems and processes did not provide adequate security for high-cost inventory within the hospital, which was another driver of cost. A lack of visibility into expiration dates for supplies resulted in supplies being wasted due to past expiry dates. Storage of supplies was also a key consideration given the location of the cancer center’s facilities in a dense urban setting, where space is always at a premium. In order to address the challenges outlined above, the hospital sought a solution that would provide real-time inventory information with high levels of accuracy, reduce the level of manual effort required and enable data driven decision making to ensure that the right supplies were readily available to clinicians in the right location at the right time.

Driving Digital Transformations for Vitro Diagnostic Medical Devices
Diagnostic devices play a vital role in helping to improve healthcare delivery. In fact, an estimated 60 percent of the world’s medical decisions are made with support from in vitrodiagnostics (IVD) solutions, such as those provided by Roche Diagnostics, an industry leader. As the demand for medical diagnostic services grows rapidly in hospitals and clinics across China, so does the market for IVD solutions. In addition, the typically high cost of these diagnostic devices means that comprehensive post-sales services are needed. Wanteed to improve three portions of thr IVD:1. Remotely monitor and manage IVD devices as fixed assets.2. Optimizing device availability with predictive maintenance.3. Recommending the best IVD solution for a customer’s needs.

Harnessing real-time data to give a holistic picture of patient health
Every day, vast quantities of data are collected about patients as they pass through health service organizations—from operational data such as treatment history and medications to physiological data captured by medical devices. The insights hidden within this treasure trove of data can be used to support more personalized treatments, more accurate diagnosis and more advanced preparative care. But since the information is generated faster than most organizations can consume it, unlocking the power of this big data can be a struggle. This type of predictive approach not only improves patient care—it also helps to reduce costs, because in the healthcare industry, prevention is almost always more cost-effective than treatment. However, collecting, analyzing and presenting these data-streams in a way that clinicians can easily understand can pose a significant technical challenge.
