Best Practices in Protecting the Technology
Systems Revolutionizing Healthcare
Executive Summary
Technology systems such as electronic medical records and digital imaging are revolutionizing
healthcare by streamlining processes, eliminating waste, improving accuracy and, most
importantly, improving patient outcomes. As these systems become seamlessly woven into
the fabric of how healthcare is delivered, their continuous operation becomes increasingly
critical. Yet, the explosive growth of healthcare IT applications is making it more difficult
to achieve continuous operation both in the data center and throughout the hospital.

While today neither electrical code nor the hospital accreditation standards of the Joint
Commission require healthcare organizations to use uninterruptible power supplies (UPS),
most have begun doing so to protect vital equipment and systems. Currently it is common
practice for healthcare facilities to install UPS backup at the device level, such as an MRI
machine or computer server. As the number of UPS units located throughout the facility
grows, however, so does the complexity of managing them to keep the devices they protect
continuously online. Additionally, device-level protection does not enable the ability to add
loads as critical systems spread throughout the hospital, particularly in the operating rooms,
patient rooms and nurses stations.

This paper outlines an approach to power protection that addresses the problems that
accompany the distributed approach. The centralized approach to power protection presented
here enables healthcare organizations to achieve higher availability and scalability for future
growth at lower cost and should be considered for all new healthcare facilities and, whenever
possible, in retrofit situations. Emerson Network Power has developed three centralized UPS
configurations specifically for healthcare settings, which we recommend based on the level
of protection and seamlessness of operation desired.
