"Or" Logic

You may be interested in patients who have either one condition or a second condition. For example, if you were interested in Patients with Lupus OR Patients with Diabetes, use “OR” logic.

To achieve this, include the Diabetes criteria in the “same criteria box” as the Lupus diagnoses.

Open the existing Diagnoses query for Lupus. Click the Edit icon to edit the Diagnoses filter.

Enter the second criteria, e.g., Diabetes. Select the desired code(s) by clicking Add Selected.

Remove any “child” ICD9 codes that you do not wish to keep (by clicking the red X for each).

Click Update (both conditions will be listed, as below).

DataDirect will display the codes within the same ‘criteria' box on the right side of the screen, indicating that the retrieved results include patients with code 710.0 (Lupus) OR patients with code 250.0 (Diabetes).
