Regional West Medical Center Deploys Nexsan Assureon to Improve Reliability and Recall Performance of Medical Image Archiving Solution

Organization Improves Object Storage Archive and Solves Business Continuity and Disaster Recovery Challenges

THOUSAND OAKS, CA--(Marketwire - Oct 4, 2011) - Nexsan®, a leading independent provider of disk-based storage systems, today announced that Regional West Medical Center1 of Scottsbluff, Nebraska, has deployed the Nexsan Assureon® to improve the reliability and recall performance of its medical archive system and to institute a solid business continuance and disaster recovery plan. The Nexsan Assureon supports a picture archiving and communication system (PACS), Horizon Medical Imaging™ from McKesson, which the medical center purchased to improve the workflow and retention of patient records.

The McKesson PACS provided immediate benefits, but its potential was limited by the medical center's legacy storage infrastructure which supported it. To treat patients effectively, Regional West's staff needed immediate access to all medical records, regardless of age. While accessing data from the existing network attached storage (NAS) solution was sufficient, the limited performance of the tape-based archive was a detriment to the entire workflow. Requests were carried to a specialist who had to research the index to identify and find the correct tape and then mount it into the library. Restoring a record took anywhere from 24 to 48 hours, and if problems occurred, the nearest support center was eight hours away. The limited performance of the library not only increased operational cost, but also inflated the dependence for maintaining records on primary and secondary tiers.

Additionally, the operational complexity of tape was jeopardizing the facilities' confidence in the ability to record new studies. Maintaining free space on primary storage is vital to reporting new studies and efficient storage utilization requires older studies be flushed to secondary network attached storage (NAS) when a high watermark is reached. However, the vulnerabilities of NAS require records be confirmed as archived before primary data can be flushed. Over time, the unpredictable performance of their outdated solution was risking the facilities' ability to write new records.

Regional West Medical Center needed a long-term image archive that would optimize the PACS' retrieval speeds, data protection and workflow. The healthcare facility also needed to mitigate operational costs caused by an increasing dependency on primary and secondary storage tiers. Finally, the facility desired a configuration which provided full off-site data replication to improve its contingency plan for disaster recovery (DR) and business continuity. With the tape library, offsite storage of records was dependent on the physical rotation of media. This process was unreliable, risky, and required significant management resources.

Assureon: Improved Data Protection & Availability
After considering several alternatives, Regional West Medical Center selected the Assureon Medical Image Archive, from Nexsan, to address the performance, reliability and offsite replication necessities described above. With Assureon, the facility has eliminated the lengthy recall for older studies and also significantly reduced the operational costs for acquiring, protecting and storing offsite data. Additionally, the self-healing and self-managing functionality of Assureon has provided unanticipated gains in productivity by reducing the overhead required to confirm effective long-term protection of patient records. These capabilities are further outlined below:

  • Data Protection -- Assureon's recurring audits preserve the original study, while access authentication and auditing ensures only authorized users can view data.
  • Ease-of-Use -- Assureon is a fully self-managing and self-healing solution that significantly reduces the burden on IT. Remote site replication, failover and DR are included with no extra fees and create a much more efficient contingency plan.
  • Efficiency -- Offloading primary and secondary storage frees up space for active data and reduces the burden of managing these systems. The power and cooling costs are also reduced using Nexsan's AutoMAID™ disk spin down technology.
  • Enterprise-class Performance and Scalability -- As an online image archive, recalling patient data is reduced from hours to minutes. Furthermore, Assureon is easily expanded and adapts to the evolving demands of healthcare facilities.

Easy, Efficient, Enterprise-Class Archiving for Secure Access to All Patient Records
Feedback from McKesson PACS end users such as radiologists and technologists has been very positive, especially regarding the speed of image recall from Assureon. The medical center's IT and PACS administrators were also surprised by the easy implementation and support for existing workflow.

"The simplicity to integrate Assureon's powerful data protection elements without custom development or complex integration was another big plus," said Donna Vogel, IS Data Services Manager, Regional West Medical Center. "In most cases, administrators can't tell when a record is being pulled from Assureon as opposed to the primary storage system, and the system improved our staff efficiency by keeping all data 'near-line' for quick retrieval. In addition, we particularly like Assureon's ability to provide a very responsive DR solution."
