HHIE

Hawaii Health Information Exchange (HHIE) stands with the Maui communities affected by the wildfires and will support health care partners by making its Community Health Record (Health eNet) portal available at no charge for six months to Hawaii providers not currently participating with HHIE who are servicing affected patients.

The secure portal includes demographics, insurance, clinical history, laboratory results, and ambulatory medication histories for Hawaii residents statewide, allowing providers to deliver optimal care to residents in the affected communities.

Please contact info@hawaiihie.org or call 808-441-1374 for more information.
