Mel Krajden MD,
FRCPC is the Director of BC’s Public Health Laboratory and the Medical Head, Hepatitis at the British Columbia Centre for Disease Control. He is also a Professor of Pathology and Laboratory Medicine at the University of British Columbia.

At the BCCDC Dr. Krajden is assembling a multi-disciplinary team to focus on understanding the key components of value-based clinical and laboratory practices that impact population health outcomes using the BC-Hepatitis C Tester’s Cohort (BC-HTC). BC-HTC contains de-identified health information for 1.5 million British Columbians tested for HCV, HIV, HBV & TB. It iincludes almost all: lab tests/results, medical visits, hospitalizations, prescriptions, cancer outcomes, and mortality outcomes. With 25 years of information, the BC-HTC is able to determine net costs of services and health outcomes by different groups & adjust for confounders. The goal is to drive value-based practices from the bench to population level -- translating discovery into practice across a range of health related questions.

Dr. Krajden serves on numerous organizations and is the author of 227 peer-reviewed publications
