HDIRS Facilitates Diagnostic Image Sharing
Founded in 2007, Hospital Diagnostic Imaging Repository Services (HDIRS) is an independent, not-for-profit corporation responsible for operating two of Ontario’s diagnostic imaging repositories as part of eHealth Ontario’s diagnostic imaging program.
HDIRS enables the secure storage and retrieval of electronic images (e.g., X-rays, ultrasounds, MRIs, CT scans) and associated patient records by authorized hospitals and independent health facilities. Combined, the two repositories store tens of millions of images and serve nearly 7.5 million people in the south-central area of Ontario (i.e., approximately 55% of the population).
Through the IT services it provides, HDIRS works to accelerate knowledge creation by facilitating better collaboration between health service providers. The knowledge not only makes for a better quality of patient care, it holds promise for a more effective and sustainable healthcare system that saves and prolongs the lives of more Ontarians.
HDIRS and GTA West DIR by the Numbers
40+ hospitals sharing
100+ independent health facilities sharing
7/14 LHINs supported
55% of Ontario's population served
44+ million exams stored
15-19% estimated reduction in repeat imaging*
*According to a study published in the Journal of Digital Imaging (“Reducing repeat imaging in hepatico-pancreatico-biliary cancer care through shared diagnostic imaging repository”)
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 and GTA West repositories would not exist without dedicated member hospitals and independent health facility clients who 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.
On April 26, 2018, HDIRS launched a fresh, new website. The new site is designed to support and reflect the activities of HDIRS- and GTA West DIR-connected hospitals and independent health facilities. Content includes a regularly updated map of contributing sites and news on the latest HDIRS projects (e.g., peer review as a shared service). HDIRS plans to layer on additional interactive website content and features over time. The new website demonstrates HDIRS’ commitment to facilitating better collaboration among health service providers.

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.
