Hawaii Immunization Information System (IIS)

Announcement of new IIS, HiSIS!

Aloha Hawaii Immunization Registry Users,

By June 16, 2025, the Hawaii Immunization Information System, currently known as HIR, will move from our current vendor to Envision’s cloud-based, vendor-hosted environment. The new system will be called the “Hawaii State Immunization System” (HiSIS). As part of this project, changes will be made in relation to:

• Onboarding HL7 message submitters
• Training clinic users
• Enrolling clinic users

Please feel free to contact the Registry Helpdesk with any questions at DOH.HiSIShelp@doh.hawaii.gov.

Provider Information

How do I learn to use the Hawaii IIS?

We will publish more information here on this website when training materials become available.

How do we submit data to the Hawaii IIS?

As a Healthcare provider participating in the Hawaii IIS, you have two methods to submit data:

• Web services using an EMR/EHR or SOAP UI application to submit real-time patient immunization records outside of utilizing the Hawaii IIS UI.
  If you are utilizing web services to submit patient immunization records, it will be necessary to schedule onboarding meetings with our Hawaii IIS vendor to provide you with web services login credentials.
• Data Exchange via the Hawaii IIS User Interface (UI). This method is where a user logs into the Hawaii IIS and uploads a HL7 patient immunization record file.
  If you are a provider using this method, the UI is up and running and you can begin uploading your backlog and current patient immunization records now.

Medicare Promoting Interoperability Program

To meet requirements, eligible hospitals and critical access hospitals must be in active engagement with an immunization registry or other type of Public Health agency to submit electronic public health data in a meaningful way using Certified Electronic Health Record Technology. Active engagement can be in the form of registration of intent, testing and validation, and ongoing electronic submission of data to the registry.
