The Transfusion Transmitted Injuries Surveillance System (TTISS) plays a crucial role in safeguarding the health of Canadians by monitoring and reporting adverse reactions to blood products, including blood components and plasma derivatives. The dedication of all 159 Ontario hospitals contributes to the continuous improvement and effectiveness of TTISS.
On October 25th, 2024, TTISS hosted a highly successful hybrid meeting, attracting just over 200 attendees. This event provided a platform for all to share insights, discuss challenges, and collaborate on enhancing transfusion safety. We were lucky enough to hear from some great speakers. A link to the speakers’ presentation can be found here: TTISS Meeting October 2025
One of the key initiatives for 2025 is the comprehensive update of the TTISS manual, which has remained unchanged since 2007. This revision aims to incorporate the latest advancements in transfusion medicine and align the manual with current best practices.
In another noteworthy development, TTISS Ontario presented a poster at the last Canadian Society for Transfusion Medicine (CSTM) conference held in Saskatchewan. The poster highlighted the benefits of the sentinel site model. Building on this success, we hope to present another poster at the next upcoming CSTM conference furthering our commitment to continuous improvement and knowledge sharing.
