HDIRS Facilitates Diagnostic Image Sharing
Founded in 2007, HDIRS is an independent, not-for-profit corporation funded by Ontario Health. HDIRS is responsible for operating two of Ontario’s four diagnostic imaging repositories. HDIRS was created by hospitals, for patients.
Since its inception, HDIRS has been focused on enabling the secure storage and retrieval of diagnostic images (e.g., x-rays, ultrasounds, MRIs and CTs) and associated patient records by authorized hospitals and independent health facilities. Sharing diagnostic images supports the movement and treatment of patients, reduces repeat scans and harmful patient radiation exposure, decreases wait times, and reduces hospital overcrowding and hallway medicine.
Combined, HDIRS’ two repositories store tens of millions of images, connect 37+ corporations and 70+ independent health facilities, and serve nearly 7.5 million people in the south-central area of Ontario, which accounts for 55% of the population.
HDIRS also serves as a shared services provider and service innovation hub for its hospital members. In addition to providing IT services, HDIRS has also invested in adding clinical value, containing costs, and accelerating knowledge creation by facilitating better collaboration among health service providers.

Member and Client Services
HDIRS provides services to member hospitals, independent health facility (IHF) clients, government stakeholders, and the Ontario healthcare system as a whole.
Member and Client Sites
The HDIRS-East and HDIRS-West repositories would not exist without dedicated member hospitals and independent health facility clients that generate and then share diagnostic imaging reports with other members. Lists of sites that contribute DI studies to the two repositories are updated quarterly. These lists may be useful for determining whether a particular patient exam is DIR-accessible.

HDIRS imaging has allowed us to now directly interface with radiologists from our referring and partner sites, allowing for a new level of interaction that will lead to ongoing improvements in the quality of imaging in communities, particularly as related to specialized and regionalized cancer care. Simply put, Ontario has spent years building centres of excellence in focused locations to improve patient care and, now, HDIRS is part of the puzzle for which these centres become focused networks of care, a critical element to the future when every Ontarian can not only receive expert care, but with much of it closer to home.
