Data Access & Disclosure Control

Linking health records is key to innovation in health care. At the same time linkage poses major challenges for disclosing patient data to researchers. The presentation proposes a methodology for structuring risk assessment of high-dimensional linked data.

In 2016, the Observatory for Population & Public Health of British Columbia launched the Chronic Disease Dashboard, an online reporting tool designed to address the gap in surveillance of chronic diseases. To protect against re-identification risks, the Ministry of Health required redacting small counts prior to releasing disease rates into public domain. These preparations, when conducted manually, have proven to be arduous, time consuming, and prone to human error.
