Vascular Implant Surveillance & Interventional Outcomes Network (VISION) CRN

Development and History of the VQI CRN

The Society for Vascular Surgery Patient Safety Organization (SVS-PSO) launched the Vascular Quality Initiative in 2010 to improve the quality, safety, effectiveness and cost of vascular health care by collecting and exchanging information among a distributed network of regional quality groups.  The VQI is modeled after the successful Vascular Study Group of New England (VSGNE), which was founded in 2002 and quickly demonstrated the ability to use aggregated data to recognize patterns of outcomes and their associated cases. Through regular meetings, regional groups define processes that effect outcome improvement in several areas in vascular surgery and allow individual hospitals and physicians to understand their results in the context of regional benchmarks.

Objectives of the VISION CRN

  • VISION is a partnership between the Vascular Quality Initiative (VQI) and MDEpiNet that directly supports the mission of the VQI to improve the quality, safety, effectiveness and cost of vascular healthcare by collecting and exchanging information.
  • VISION facilitates low-cost, but high value real-world effectiveness research though the creation of a national repository of linked clinical-claims analytic datasets
  • VISION measures long-term outcomes of vascular surgery procedures, including survival, effectiveness of the procedure, long-term device failures and revisions (reinterventions), readmissions and surveillance imaging using VQI-Medicare linked datasets.

 Governance – Current Status

  • All of the data contained in the VQI is maintained under SVS-PSO.
  • Specific Data Use agreements have been developed between the Centers for Medicare and Medicaid Services, the Dartmouth Institute, Weill Cornell Medical Center, and the SVS-PSO to allow VISION to match patients who exist in both the VQI registry and Medicare claims, as well as other administrative data sources, and use this data for long-term outcomes evaluation.
  • A Steering Committee with representatives from the VQI, Medical Device Industry, and the FDA sets the strategies and priorities of the organization.

Work Plan

  • VQI-Report Generation: We will generate reports and feedback mechanisms to participating VQI Sites to help improve the care provided to patients with vascular disease.

  • Research: Our team will engage in research to examine the long-term effectiveness of vascular procedures and disseminate findings through presentations and publications

  • Analytic Support: Our analytic team will facilitate research projects conducted by other investigators by executing analyses on the VQI-Medicare linked data.
  • Updating Registry-Claims datasets: Each year, we will review, update and refine our algorithms for identifying late events in Medicare claims and generate new datasets with the most current year of Medicare claims data available.
  • Evaluating Devices Using Claims and Registry Data (EDUCATE): We will use data from industry trials to provide a “gold-standard” against which to validate our linkage-derived CRN data in VISION. This will provide an external source for validation of the data sources that emanate from claims-based linkages, and provide valuable feedback to regulators, industry, physicians and patients about the actual accuracy, precision, and reliability of “Real World Evidence” produced by CRNs.
