Perform a Reverse Allergy Check

This topic provides information about performing a reverse allergy check using Oracle Health EHR.

When you attempt to add a new allergy or modify an existing allergy, the system cross-references the allergy substance with the patient's active medication list and notifies the user if a potential interaction is detected. Reverse allergy check can also be performed manually for the entire profile of Active allergies by selecting Reverse Allergy Check.

The system displays the following behavior depending on the type of allergy that you are viewing, adding, or modifying:

• Multum Drug Allergy: If you add or modify a Multum drug allergy and the patient has an active medication order for that drug, the system displays a message indicating a drug-allergy interaction exists and identifies the specific order or orders causing the interaction. Review the patient’s medication order or treatment plan and make any necessary adjustments to prevent an adverse reaction.
• Drug Allergy: If you add or modify a non-Multum drug allergy, the system displays a message indicating that non-Multum allergies cannot be checked for drug interactions.

To manually perform a reverse allergy check:

1. Open the Allergies page.
2. Select Reverse Allergy Check. An icon is displayed next to each allergy indicating one of the following results from the reverse allergy check:
   • No drug interaction found
   • Non-Multum allergies cannot be checked for drug interactions
   • Drug interaction found
   • Error
3. Assess the patient's orders and modify as necessary to avoid an adverse reaction.
