CHAPTER 5 Components of an HCM System 53
✔✔using address directories and selecting addressees
✔✔when communicating with other healthcare institutions: support for the
harmonization of patient identification numbers. In a simple case, support
can involve removing the in-house patient ID from the metadata. If the
patient ID persists, the issuer of the patient ID should also always be transmitted,
so that the recipient knows the number range in which the
contained patient ID is valid.
✔✔mechanisms for rule-based automated dissemination of data
✔✔data upload to internal or external portals. The portals themselves can also
be part of the data output of an HCM system
✔✔ export data to a file system or to media such as DVD or USB stick
Put It into Cold Storage:
Archive Management
Both medical concerns and legal regulations require long-term archiving of
medical
data. However, the data must not be stored in an arbitrary way, but in an
audit-proof manner.
An archive is audit-proof if it is sufficiently ensured that files are
neither lost nor changed from data receipt through transport to
final storage and beyond. In addition, they must be retrievable
within a short time.
Up to the delivery of documents to the »archive administration« of the HCM
system the authenticity should be guaranteed by a digital signature or a time
stamp. Within the HCM strategy, the component »archive management« then
supports audit-proof archiving. The »archive administration« should fulfil these
requirements:
✔✔ Integration of long-term storage. The highest data security is provided by
write-once storage (WORM storage). Basically, an HCM system should
support common archive solutions as well as storage in the cloud. An
existing
vendor neutral archive (VNA) can also be integrated into the
HCM system.
