Generators

Generators refer to the data sources used to set de-identification values in Workgroup.

Generator Settings

Each generator has its own settings, which you can edit from the Value Generator tab. Click on the generator name to navigate to the setting details.

Advanced Mode

Allows you to use more than one generator for a single field, edit the output format or preformat values. You can also set preconditions to conditionally apply the de-identification rule.

Preformat Value

(Only available in Advanced Mode)

 Use this to format the original value before it is processed.

This is useful for generators that include the original value or ID fields. Here are two usage examples:

a) In an unstructured data field,  you may wish to remove a value that is not contained elsewhere (not already cloaked in another field):

If you know the field may contain a reference to an ID defined as ‘ID-999999’, you would:

1.  Cloak the field using an Unstructured Data generator.

2. Set the following preformat for the unstructured data:

Find what:

ID-\d+

Replace by:

ID-XXXX

b) If you have the same patient ID number in two systems, but formatted differently, you could  format them so that both systems change to the same ID format and  can both be recognized as the same patient. Having the same ID will provide continuity of the message flow for a patient (messages will be cloaked using the same fake data):

If, for example, PID.2 is defined like this for the two systems:

First system: ID:123456

Second system: 123-456

 You would need to:

a) Set the field PID.2 as an ID (by checking the ID column).

b) Define two preformats like this:

Find what:

^ID-(?<ID_Number>\d+)$

Replace by:

${ID_Number}

Find what:

^(?<ID_Number_Part_1>\d+)-(?<ID_Number_Part_2>\d+)$

Replace by:

${ID_Number_Part_1}${ID_Number_Part_2}

Now both systems will treat PID.2 as being ‘123456’ and match and cloak the messages properly as being the same patient.
