One secure repository. Decades of linked data.
PRDS draws on a centralized, patient-level repository held on a secure server inside the Alberta Health Services firewall. It brings together administrative and clinical data from across the province — ready to be extracted, linked, and de-identified for approved research.
Inside the firewall
Patient-level data is stored and processed within the AHS security perimeter. Extractions never leave that governed environment until they're approved and de-identified.
Linked at the patient level
A person's hospital, ambulatory, pharmacy, lab, and registry records can be linked into a single longitudinal picture — the foundation of strong observational research.
Privacy by design
Access is bound to ethics approval, operational review, and Alberta's privacy legislation, with de-identification before any dataset is released.
13 provincial data sources, one linkable whole
