The Premier Neurointerventional and Cerebrovascular Surgery Registry

The NeuroVascular Quality Initiative-Quality Outcomes Database (NVQI-QOD) is a clinical registry dedicated to driving improvements in patient care by providing access to structured, validated data on real-world populations.


Developed by physicians for physicians.

NVQI-QOD has accumulated over 20,000 neurointerventional and cerebrovascular surgical procedures with registry participants including many of the top medical centers in North America.

Participation in the NVQI-QOD enables physicians, surgeons, and hospitals to assess their incidence of technical efficacy, clinical outcomes, safety and complications, length of stay, and other critical metrics in comparison with national benchmarks for quality assurance and improvement.

There’s a reason leading centers are joining our mission

“There is no substitute for real-world data on care delivery. In cerebrovascular disease, minute details can have a crucial impact on outcomes for patients. Being able to see their own data, and use the information to improve care, greatly impacts hospitals and the patients they serve.”
Dr. Fraser, FAANS, FAHA, NVQI-QOD Participant
Director of cerebrovascular surgery, UK HealthCare

Who We Serve

Registry History & Structure

The Society of NeuroInterventional Surgery (SNIS) launched the NVQI registry in 2013. Governed by the SNIS Patient Safety Organization (SNIS PSO), the registry began with the objective to improve procedural quality and patient care. In 2019, it grew into the NVQI-QOD as a result of a partnership with the American Association of Neurological Surgeons (AANS), who added the cerebrovascular QOD participants of its registry and outcomes subsidiary, the NeuroPoint Alliance (NPA). This partnership provides a comprehensive representation of clinical thought leadership. The NVQI-QOD is powered by PATHWAYS, the Fivos cloud-based registry platform.

The PSO infrastructure allows the collection of clinical data associated for quality improvement purposes without requiring individual patient consent or prior approval from an Institutional Review Board (IRB).
