Use Multiple Tables |
It makes sense to have multiple tables in each message's table grammar, rather than having one monolithic table for each message. This makes mapping easier since you can re-use mappings from message to message.

Multiple IDs Per Patient One question that comes up quite often is how to deal with patients that have multiple IDs. This situation arises frequently within the US health system because different independent hospitals that might have treated the same patient are amalgamated into a larger group. The CDC also has to deal with this problem since they collect patient data from a large number of different organizations. A good technique to deal with this problem is to create a Patient ID aliases table in the VMD file. This maps alternate IDs to the specific patient in your system. In this way Iguana can support many patient IDs for each patient. | ||
