You have just been tasked with setting up an HL7 interface to a disparate system and you don’t have the resources to accomplish the task. This is not an uncommon situation and because HL7 is not standard even within the same version, much alone across versions i.e. 2.3 to 2.5.1, this now becomes a challenging project. The issues range from the data itself, the client sending physician custom ids, or the structure within the OBR segments. The format of HL7 segments vary and typically earlier or later versions are not compatible with one another. To add even more complexity to the situation, once the format issues are worked out, then both sides of the interface will need to agree upon the connectivity – TCP/IP port to port, SFTP, etc. HL7 to HL7 interfaces appear to be straightforward on the surface, but when the implementation process begins it becomes apparent there is much more complexity to them. For these reasons and more, it is highly recommended to engage healthcare IT experts like Roxiticus, who has the resources to configure, develop and complete successful HL7 interface projects.
