Background
TTISS evolved from a pilot project in 1999-2002 involving four participating provinces – British Columbia, Québec, Prince Edward Island, Nova Scotia – and has now become the national surveillance system for capturing moderate and serious adverse transfusion events reported in Canada. The proportion of hospital sites reporting nationally currently represents 70% of red cell transfusion occurring in Canada per year. In addition to its surveillance properties, the TTISS program allows for assessment of new transfusion risks, including emerging pathogens and the monitoring of trends to determine increases in known risks.
Participants
TTISS is supported by input from front line health care workers, the National TTISS Working Group and the
National Working Party for Data Review for improvement of surveillance activities. TTISS collaborates with Canadian Blood Services (CBS), Héma-Québec (HQ), and Canada Vigilance (Health Canada) for reconciliation of all data collected in order to ensure complete and accurate reporting. TTISS strives to produce quality data and strictly adheres to the definitions for the classification of reactions. Data are disseminated regularly to stakeholders through
TTISS Program Reports.
Status
TTISS continues to evolve, change and improve nationally. Future initiatives include upgrading the TTISS database to a web-based system which will incorporate a module for more in-depth reporting of transfusion-related errors. Also, the Public Health Agency of Canada (PHAC), in collaboration with stakeholders, has developed a standardized
Guideline for investigation of suspected transfusion transmitted bacterial contamination which was released in January 2008 on the Canada Communicable Disease Report (CCDR) website.
BC
British Columbia, through the BC Provincial Blood Coordinating Office (PBCO), was one of the four original provinces participating in the 2000 national pilot. In 2010, BC hospital participation in TTISS accounts for more than 90% of all red cell units transfused in BC.
In 2009-2010, BC reviewed and revised its processes related to transfusion reactions. The work of cross-professional teams (nurse, TM-MD and technologist) resulted in the release of provincial model documents that merge TTISS reporting elements with standardized provincial best practice with respect to bedside recognition and reporting of the reaction, laboratory investigation process, and TM-MD interactions. These documents are collectively called the Transfusion Reaction Toolkit.
