Digital Health Immunization Repository (DHIR)
The purpose of the DHIR is to expand immunization data access options for healthcare providers and the public, for submitting and retrieving immunization data.
What is it?
The Digital Health Immunization Repository (DHIR) is a centralized repository of standardized electronic immunization data which forms the foundation of a broader interoperable ecosystem for immunization data in Ontario. The goal of the DHIR is to improve health outcomes by making comprehensive immunization information accessible in real time to support health care providers in clinical practice and to engage the public as active partners in managing their health.
The DHIR primarily supports data sharing for public health purposes; Ontario’s 36 public health units access the repository through Panorama. However, the public is also able to access and update their immunization records through a web-based tool called Immunization Connect Ontario/Digital Yellow Card (ICON/DYC).
An upcoming release will make it possible for health care providers to access and update the DHIR through a clinician-oriented version of the ICON web tool. Intended approaches for expanded clinical access include DHIR integration with regional and provincial clinical viewers, and direct integration with electronic medical record (EMR) systems. Expanded public (consumer) access will be accomplished through DHIR integration with consumer applications and patient portals.
The DHIR specification describes the data store environment and web services for submitting and retrieving immunization data. The DHIR Release 3 FHIR (Fast Healthcare Interoperability Resources®) Implementation Guide implements FHIR Standard for Trial Use (STU) 3.
