In-Home Asthma Trigger Intervention Model (IHAT)

Download IHAT Intervention Model

Using the IHAT to Assess and Reduce Asthma Triggers

  • The IHAT is designed to assess for In-Home Asthma Triggers, and to assist in pinpointing potential improvements to help reduce in-home asthma triggers.
  • Use the IHAT to help create a Family Action Plan to help the client make improvements to reduce in-home asthma triggers
  • Involve the client in the IHAT to help get the best answers. Certain inspection-based questions may be best to do on your own.
  • Conduct an IHAT as both an initial assessment, and then reconduct it as a follow up assessment to document improvements in in-home asthma triggers due to intervention.
  • A reduced IHAT score indicates improvement. You can calculate improvements as a percentage for documentation and reports.

Creating the Family Action Plan

  • Create a Family Action Plan (FAP) with recommended improvements for the client.
  • Certain in-home asthma triggers are house-based, such as leaks. Certain triggers, however, are client-based, such as smoking, hygiene, and spray and cleaner use.  How you address these client-based triggers will depend on your relationship to the client.
  • Focus areas for improvement on IHAT questions and sections where the client scored high.
  • Use the Intervention Suggestion Library to help create the FAP.

Providing Resources

  • If possible, provide resources for areas needing improvement.
  • The resources that are available will differ depending on your program.
  • When no resources are available, attempt to provide an educational resource.
  • Update Resource Library as new programs become available.

Adapting the IHAT

  • The IHAT can be adapted to meet your program needs
  • This may result in the need to raise or lower the total possible IHAT score.
