TRIADTM Site Server is a rules-based software package that passively monitors HL7 messaging within your facility to identify, anonymize, and transmit IR procedure data from your site to the NRDR IR registry.

In the identification stage, TRIAD flags HL7 messages with an observation segment (OBX) that matches the list of IR registry procedures. These procedure names are defined by the SIR standardized report templates used to structure registry data.

Next, TRIAD anonymizes and prepares the data for transmission. TRIAD uses a variety of operations to protect confidential data. In most cases, data elements such as Mother’s Maiden Name, Patient Address, etc. are completely removed because they are not needed for measurement. Other fields are computed; for example, a unique patient ID is calculated using a hash algorithm so that a single patient can be tracked over time without sending sensitive information, such as a social security number. Another example is the patient’s DOB, which is used to calculate the age at the time of the procedure. The age is sent and the actual DOB is removed. The complete list of anonymization rules is available in the TRIADTM Site Server for the IR Registry installation guide.

Once the data elements are anonymized and prepared they are transmitted via internet from the facility's TRIAD server to the IR registry via the NRDR portal.
