Ontario Transfusion Transmitted Injuries Surveillance System
TTISS-ON collects moderate to severe transfusion reactions that occur as a result of the transfusion of blood products (blood components and plasma derivatives) in Ontario Hospitals.
With over 90 hospitals participating, this accounts for 80% of the transfusion activity in Ontario. The Ontario Transfusion Transmitted Injuries Surveillance System (TTISS-ON) is contracted by the Ministry of Health (MOH) and the Public Health Agency of Canada (PHAC) and is committed to the development of a comprehensive program for reporting Adverse Transfusion Events (ATEs) in Ontario as an important part of a national hemovigilance system implemented in 2001 by the Infectious Disease Prevention & Control Branch of the Public Health Agency of Canada (PHAC).
