Research Focus

My research focuses on developing tools that ensure quality in the delivery of cancer care across the community. Advances in science have made this major health problem a treatable disease, yet up to a third of patients diagnosed with cancer do not receive recommended care. These deviations from best care have been documented for all aspects of cancer management, from screening and diagnosis, to post-treatment follow-up and end-of-life care. They impact recurrence, survival, quality of life and costs. Deviations in cancer care quality raise important questions about translating scientific knowledge into clinical practice. Interventions to manage these deviations are currently challenged by the lack of an integrated cancer care monitoring strategy. Health informatics technology (HIT) represents the ideal tool to address this challenge. We aim to develop informatic tools that would allow us to integrate currently existing and separately maintained clinical, service, and competency data repositories using HIT.
