A VNA Maintains Patient Privacy and Security
A VNA needs to support audit trails in a manner that is easy accessible and retrievable. Authorization rules are typically provided by a different application but could also be part of the VNA. This also satisfies legal concerns, as it can be proven that a certain physician retrieved a particular case. Instead of each device keeping these audit trails in a semi-proprietary manner, it makes the life of a system administrator much easier if this information is updated and maintained in a central location, in a standard format as specified by IHE in its ATNA profile definition.
Data integrity is also critical, which is why some vendors implement digital signatures to make sure that alterations can be detected.
Lastly, there are some institutions that require non-volatile media like magneto-optical devices or other write-once media, for their long-term archiving. This is because the information on rewritable media such as RAID’s could be compromised by viruses or other malicious software. It is not possible if the data is burned to a medium that is not erasable and cannot be modified.
