The Heart and Stroke Foundation, CorHealth Ontario and the Canadian Institute for Health Information (CIHI) have worked in partnership to create a new Stroke Special Project that will be collected in CIHI’s Discharge Abstract Database (DAD).

Project 440 collects additional data on patients who undergo endovascular thrombectomy for large-vessel occlusion causing acute ischemic stroke and extends stroke data reported to the DAD using special projects. Stroke Special Projects enable the capture of key process and outcome information based on the Canadian Stroke Best Practice Recommendations and support stroke surveillance, quality improvement, benchmarking and Accreditation Canada’s Stroke Distinction program. The Stroke Special Project series includes

  • Stroke Special Project 340 Canadian Stroke Strategy Performance Improvement (DAD/NACRS)i
  • Stroke Special Project 440 Endovascular Thrombectomy (DAD)
  • Stroke Special Project 640 Canadian Stroke Strategy Performance Improvement II (DAD/NACRS)
  • Stroke Special Project 740 Alpha FIM® (DAD)

To support data collection and submission, these specifications were provided to licensed DAD vendors in December.


Facilities that perform endovascular thrombectomy, also known as collaborative stroke centres or regional stroke centres in some jurisdictions, are encouraged to participate. Data collection can begin either in fiscal year 2018–2019 or in fiscal year 2017–2018 for those facilities that would like to participate for the remainder of this open fiscal year.
