Welcome to TTISS Ontario

Adverse Transfusion Events (ATEs) are a serious concern to patients and their caregivers, and must be thoroughly documented in order to improve clinical practice outcomes for the future.

What is an adverse transfusion event (ATE)?
The Public Health Agency of Canada defines these events as: 

“..an undesirable and unintended occurrence during or after the administration of blood, blood components, or plasma derivatives.”

 

The Transfusion Transmitted Injuries Surveillance System (TTISS) is maintained by the Public Health Agency of Canada (PHAC) to collect data on ATEs resulting from the therapeutic use of blood, blood components, plasma derivatives and recombinant products across the country.  In Ontario, hospital transfusion services report ATEs using this national system.  Several hospitals have databases installed, into which they enter data collected post-transfusion.   Until recently, those systems were not connected in any fashion so timely summaries were unavailable. Ontario transfusion personnel, concerned about ATEs, did not have access to information to improve practice.

That is changing.  As part of the Blood Programs Coordinating Office, Ontario Ministry of Health and Long-Term Care initiatives, a centralized database of information from province wide TTISS reports is being constructed.  The McMaster Transfusion Research Program and Southwest Ontario Regional Blood Coordinating Network is the home to an Ontario TTISS Coordinator and a team of individuals devoted to various aspects of operational and clinical research in Transfusion Medicine.
