With the American Recovery and Reinvestment Act (also referred to as the U.S. economic stimulus package) slated to include $19 billion for electronic medical records (EMR), the role of data storage in the healthcare industry is gaining more attention than ever before.
But the healthcare industry is facing the same challenges as most other vertical industries: dealing with an exponential amount of data growth at a time when compliance, regulations and increasing types of media-rich files are putting added pressure on storage professionals.
Michael Sullivan, a managing director at Los Angeles-based Sinaiko Healthcare Consulting Inc., has found that many healthcare providers lack transparency into their information technology systems. In addition, IT professionals struggle in a culture that puts a big emphasis on software applications, rather than on hardware and a holistic view of the computing environment.
"When you talk to IT departments at hospitals, it's rare to actually talk to someone in charge of hardware," said Sullivan, who has consulted on healthcare IT operations for more than a decade.
Despite often having input from chief information officers (CIOs), many of the purchasing decisions at the hospitals where Sullivan consults are left to board members, he said. "These purchases are often made without thought as to whether a new system can talk to other systems and what the storage implications are," he said.
Brian Babineau, a senior analyst at Milford, Mass.-based Enterprise Strategy Group (ESG), said hospitals often have end users (doctors) that are used to long-standing legacy systems. "No hospital believes that there is no benefit in digitizing records, and they all understand that they can get a significant reimbursement or even paid to implement electronic records," he said.
"The initial cost isn't the problem," Babineau noted. "It's the operational burden of convincing baby-boomer doctors, who are very unfamiliar with the technology, to welcome new technologies, processes and ways of doing things."
Derek Woo, who's also a managing director at Sinaiko Healthcare Consulting, said the healthcare clients he's met have typically inherited a mix of systems that aren't well integrated. They're now faced with the pressure of digitizing healthcare records and establishing a comprehensive records-retention policy.
"If you look at what these healthcare organizations actually have installed, it's really a hodgepodge of things that are primarily file-server-based," Woo said.
Vendors offer wide range of products
Some storage vendors offer very specific products designed for the healthcare industry, including BridgeHead Software Limited's PACStore and Bycast Inc.'s StorageGrid line. Both of these product lines support Health Level Seven (HL7)-developed standards as well as Digital Imaging and Communications in Medicine (DICOM), which is a standard for handling, storing and transmitting medical imaging information.
But ESG's Babineau said this approach is rare, as most storage vendors don't support these standards; instead, they let the application handle them. "So these vendors pitch why they're the most cost-effective at handling medical images because healthcare providers care about cost," he said.
Many hospital information system (HIS) manufacturers, like Cerner Corp., Eclipse Solutions Inc. and Epic Systems Corp., have partnered with storage vendors like EMC Corp. and Hitachi Data Systems, which has led to a heterogeneous mix of systems and a wide range of products in the healthcare space.
EMC, NetApp and Symantec Corp. have made a big push in the area of compliance and data security, Sinaiko Healthcare Consulting's Woo said, but he believes storage vendor activity has slowed on this front. "It seems like their foot is off the pedal and they're trying to figure out what the healthcare vertical wants and needs," he said.
Storage vendors and users in the healthcare industry should be concerned with operational measurements, since many healthcare providers will have to quantify their IT progress to receive stimulus funding.
"Providers should measure how much EMR they have online now vs. how much they could have by implementing a retention strategy that incorporates archiving and lower cost storage," he added.
Healthcare providers can also leverage storage technologies to enhance their electronic medical records efforts with data archiving and data management software, ESG's Babineau noted. One software category has the capability to move a primary data application environment to a low-cost environment, just like the Bycast and Bridgehead offerings do.
Another type of software stores a large amount of capacity for long periods of time while facilitating reasonable access, Babineau said. Products in this area include EMC's Centera, Hewlett-Packard (HP) Co.'s Medical Archive Solution (MAS), Hitachi Data Systems' Hitachi Content Archive Platform (HCAP), IBM's System Storage DR550 and Nexsan Technologies Inc.'s Assureon.
