SVS PSO Data Analysis Guidelines for Use

In order to ensure protection of de-identified datasets and fair access for members, investigators should familiarize themselves with the SVS PSO guidelines and policies on use, listed below.

Global guidelines for SVS VQI Dataset Requests

  1. Data Security: All investigators and team members are responsible for security of datasets, which are only to be used for the project for which they were approved.
  2. Dataset Access: Investigators have free access to the datasets to which their center has subscribed, providing that their center has at least 50% Long Term Follow-Up for the registry data being requested. Please confirm that your center subscribes to the dataset(s) you wish to analyze before submitting your proposal.
  3. Comparison of Specialties: The SVS VQI is a multi-specialty registry and therefore the SVS PSO Executive Committee does not allow comparisons between specialties in submission topics.
  4. Device-related Datasets
    • Regional datasets are not available for device-specific projects due to concerns around the low “n” in regional datasets,  industry sensitivities around proprietary devices and the potential for  identification of physicians.
    • National datasets for device-specific projects will only be released after completion of the steps outlined in the SVS PSO Device Identification Policy (click here to read the policy in full).  Please note that the additional safeguards in the Device Identification Policy require additional time to complete so you may wish to build in additional time to guarantee that you can meet deadlines for journal or event submission.
  5. Medicare-Match: Medicare-match datasets are governed by a data use agreement between Weill Cornell Medical College and CMS (please click here for more details).
  6. Dataset Refresh Requests: One dataset refresh is allowed within 24 months of the approval of the original study – please email Melissa Latus if you wish to receive a dataset refresh.
  7. Overlap of Topics: The RAC has dropped the requirement to avoid overlap as a criterion for SVS PSO RAC approval. Research protocols now need only to demonstrate feasibility that the research can be accomplished using data available in the SVS VQI dataset. Overlap with an existing project will not be used as grounds for rejection of a research protocol application. The RAC are unable to ensure that no overlap exists, because of the large numbers of active research efforts underway. Therefore, researchers will need to ensure that their work takes into consideration what has already been approved as a research topic. Please check your topic using the RAC Search Tool.

data analysis tools

We have tools to help you get started. Whether you need help with the process for requesting data, or wondering how to go about submitting a proposal, we can help.

SVS VQI publications

There have been over 600 published articles using SVS VQI data, please. See below for the latest list of publications.


Medicare-match datasets are available for some datasets on a limited basis – please read the overview and dataset details here before you request these datasets to ensure that the data will benefit your study. The Medicare-match data are provided under a separate Data Use Agreement through Weill Cornell and there is a 3 – 6 month further lead time, once the project is approved.

data analysis & Research

SVS VQI physicians may request de-identified datasets from each SVS VQI registry for analysis. The SVS PSO Arterial Research Advisory Council (RAC) reviews and evaluates requests for datasets by investigators, who provide the RAC with a description of their proposed project.

Proposals are evaluated by the Arterial Research Advisory Council every other, and the Venous Research Advisor Council in the other months.
