Staten Island University Hospital
Infrastructure Enables High-Speed Imaging to the Point-of-Care
The Challenge:
Service Area: Network Challenge:
Bandwidth-intensive healthcare applications require high-performance network
infrastructure, and Staten Island University Hospital rapidly developed a
network infrastructure that can now support the delivery of medical imaging
applications to the desktop. By building a reliable, high-speed network
infrastructure based on Asynchronous Transfer Mode (ATM), the hospital now
supports mission-critical, client/server applications, including the online
delivery of medical images from central servers. The hospital is now deploying
ATM-to-the desktop, allowing healthcare practitioners to download and review
imaging modalities at the point-of-care.
Staten Island University Hospital is an Integrated Delivery System (IDS) and
is one of the most efficient inpatient centers in the state. A member of the
North Shore LIJ Health System, Staten Island University Hospital is a 643-bed
not-for-profit teaching hospital that leads the New York area in its percentage
of managed care patients. In less than three months, Staten Island University
Hospital built an ATM network based on the Centillion 100™ from Nortel Networks,
a Nortel Networks business.
Later, the hospital expanded the network to deliver ATM-to-the-desktop. In
this phase, the hospital installed Nortel Networks System 5000 BH™ hubs in the
data center and redeployed the Centillion 100s to serve as edge devices that
feed data onto the high-speed backbone.
By expanding the backbone and increasing capacity, Staten Island University
Hospital has driven 155 Mbps multimedia connectivity to ATM local area networks
(LANs) throughout the healthcare facility. The hospital is aggressively forging alliances to create a vertically
integrated continuum of care that links the hospital with physicians, nursing
homes, home health providers, pharmacies, and medical equipment providers. This
linkage requires a physical network that connects users throughout the continuum
of care. Since each affiliate has different computing systems with different
operating systems and protocols, the computing network needed to be flexible.
"Our CEO and President, Rick Varone regards the network as something that both
attracts physicians to our group and serves as a barrier to exit," said Patrick
Carney, the hospital's Vice President and Chief Information Officer. "With
capitation, integration between the hospital and the physicians is critical to a
successful risk contract. The robust and scalable network we have built helps us
provide value to the physicians, as it will help them integrate and access
important patient data. Managed care has resulted in tighter hospital/physician
relationships. The technology infrastructure is the glue that keeps them
together." The hospital decided to focus first on building the necessary
infrastructure and deploying new client/server applications that would improve
patient care and business efficiencies. Hospital executives and the Board of Directors signed off on the proposed
Information Technology (IT) Delivery Model, and the IT department had to rapidly
implement the plan. The first step was to install backbone switching, and after
evaluating products from 3Com, IBM, and Nortel Networks, Staten Island
University Hospital chose a complete network solution from Nortel Networks.
According to Rick Jerothe, Director of PC LAN Services, "Flexible and
scalable ATM switches were our top priority, but we also needed hubs, routers,
network management, and remote access servers. Nortel Networks offered the only
product line that met all of our requirements-from the backbone out to the
remote office. We had prior experience with Nortel Networks and were impressed
with the company's products and services, so we chose the network solution from
Nortel Networks." Staten Island University Hospital has three main campuses in the same county
spread out over a 10-square mile area, and over 200 other locations where
network connectivity is provided throughout other regions of New York. On Staten
Island, there is a North Site Hospital and a South Site Hospital, each with
several buildings concentrated around the main hospital. The third campus site
is One Edgewater Plaza, which houses hospital administration and the data
center. Previously, the hospital had islands of Ethernet LANs at each facility
and a few Token Ring local area networks (LANs) in the data center. The three
locations were connected over T1 lines, which were primarily used for voice but
also carried AS400 traffic to support over 1,000 dumb terminals.
Because the hospital had an extremely short time frame for implementation,
management selected HBO & Company (HBOC) to install the network and
establish network management processes. HBOC provided most of the software
applications, and was also contracted to help develop and refine the
organization's network upgrade strategy and install the network. HBOC worked
closely with IT staff and Nortel Networks engineers and established a detailed
network design and installed the core ATM network in less than three months.
The network - code-named "StatNet" was originally based on Centillion 100
switches located in each of the three sites and connected over a switching
fabric of 155 Mbps ATM. The LAN traffic at each site was standardized onto 10
Mbps Ethernet LANs, which were consolidated onto BayStack hubs, which in turn
were connected to System 5000 intelligent hubs for access to the backbone
network. Backbone traffic was routed through a Backbone Concentrator Node® (BCN)
multiprotocol router from Nortel Networks, which also provides Internet access.

A Nortel Networks Access Node (AN®) was installed in each site for backup and to provide Internet connectivity.
The hospitals were connected over the wide area network using OmniStream ATM Services from Teleport Communications Group. Staten Island University Hospital uses Nortel Networks Optivity® network management solution running on an RS6000 workstation. Optivity allows network administrators to automate the management of distributed network resources. The network staff administers user moves, adds, and changes from the management console by dragging and dropping icons on the computer screen.
The network went live to support over 2,000 users who immediately recognized major performance improvements. The hospital then began further deployment of distributed client/server applications to improve patient care and business operations. The name StatNet was chosen, not because of the Staten Island location, but rather for the medical term "stat" (which means immediate). StatNet's objective is to provide clinical information throughout the continuum of care rapidly and reliably.

Once the backbone infrastructure was initially in place, the hospital began deploying the new client/server applications. Most are based on Windows NT servers, but some reside on UNIX RS 6000 minicomputers and can be accessed from PCs at all locations. The hospital purchased HBOC's Pathways 2000® product line and immediately began implementing several applications. These data warehousing applications provide a high level of security and will allow physicians to easily create custom queries to the central repository. Intelligence is built into the system allowing physicians to perform online analysis.
Nava Birnberg, Director of Health Information Management, said, "We work closely with physicians, nurses and the IT department to define data requirements, develop, and implement systems that improve the quality of care with a focus on the availability and security of health information. The network allows us to make healthcare information and medical records easily available to authorized caregivers throughout the hospital. In fact, we have found that the network provides a higher level of patient information security than our previous paper-based medical records offered."

She continued, "In the past, information could have been lost in transit or it might have been difficult for the caregiver to access a particular item of information in a patient's file. We are moving toward standardized information which will be readily available to authorized caregivers over the network infrastructure. We continuously improve electronic access to healthcare information to make network access user-friendly, secure, and efficient. Our objective is to provide clinicians with information at their fingertips yielding positive outcomes on quality and continuity of care to our patients."
Pathways Health Network Management™ integrates clinical and operational applications by creating a master patient index that allows data to be entered on a patient via any PC on the network. This allows the hospital to more efficiently serve patients by eliminating redundant data collection and streamlines registration and benefits processing.
Financial applications are being migrated from AS400 so they can be closely integrated with the clinical applications. Accounts payable, purchasing, inventory, general ledger, fixed assets, and time-and-attendance packages were also brought online. Manual payroll was dramatically reduced because hourly employees can now swipe identification badges through card readers at each location. Each card reader is connected to the network and generates payroll data automatically.

Since Staten Island University Hospital had developed a flexible and scalable network architecture, migration to high-speed desktop connectivity was fast and cost-effective. Higher capacity System 5000 BH ATM switches were deployed in the network core, and Centillion 100s were pushed out onto the hospital floors. "We recently pushed the Centillion 100s from the core network out to the wiring closets to serve as edge devices that can switch either Ethernet or ATM traffic to LANs throughout the hospital," said Jerothe. "This strategy allows us to minimize network costs since we re-use the installed network devices in productive manner. It also gives us the flexibility to deploy ATM LANs initially to those segments that require access to centralized radiology applications."
The PC's on these hospital segments were upgraded with ATM adapter cards, and they can now get real-time access to images stored on servers in the data center. This allows physicians to rapidly diagnose and treat the patients, since healthcare practitioners have online access to images that would have previously been hand-carried on films to the point of care. "We're real proud that we built the network right the first time," said Jerothe, "The upgrade was easy and went smoothly, and we have an infrastructure architecture that allows us to scale to meet new applications or user requirements."
| Remote Access Now Available to Over 200 Locations | [ TOP ] |
Remote access was deployed using Nortel Networks remote access servers and frame relay services from the Teleport Communications Group (TCG) to allow Staten Island University Hospital to expand its service area while creating tighter links with affiliated organizations. Staten Island University Hospital uses Teleport's Frame Relay Services to connect physician practices, clinics, nursing homes, home health services, and pharmacies. There are over 200 locations now connected to the enterprise healthcare network, allowing Staten Island University Hospital to support the entire continuum of care. The hospital also allows dial-up analog and ISDN remote access for off-site departments, smaller physician offices, remote departments, business partners, and staff members working from home.
As the hospital aggressively introduces new applications, Carney is confident that the network infrastructure is in place to support any future requirements for local or remote access. Carney said, "Our users are continually adding new applications that improve clinical care or operational efficiency, and we know we have built the infrastructure that provides both the flexibility and scalability to meet any future requirements. With Nortel Networks and HBOC, we've built a network that can support just about anything I can plug into the network - and that gives us tremendous flexibility to meet the needs of our patients."
