What is VISION? Stakeholders from every sector stand to benefit from a more complete and efficient method of medical device surveillance. The Vascular Implant and Interventional Outcomes Network (VISION) is a partnership between the Society for Vascular Surgery Patient Safety Organization (SVS-PSO), the U.S. Food and Drug Administration, and the Medical Device Epidemiology Network (MDEpiNet) that aims to develop a better, faster, cheaper method of device surveillance in the vascular device space. VISION works toward this goal by linking the Vascular Quality Initiative’s (VQI) national registry of vascular surgery procedures with Medicare Claims. For patients and the physicians who care for them, reliable data on device performance translates into informed decisions and better care for patients when they need it. For Industry, greater use and acceptability of Real-World Evidence (RWE) to monitor devices post-approval offers the potential for future cost savings and more efficient pathways for reporting and expanded use. Lastly, for regulators, the use of RWE is essential to achieving the desired goal of total life cycle surveillance.
What has VISION accomplished? As a NESTcc Demonstration Project, VISION has linked the VQI registry for Endovascular Abdominal Aortic Aneurysm Repair (EVAR) with New York’s all-payer database known as SPARCS (Statewide Planning and Research Cooperative System) from 2003 to 2015. This allowed us to compare the rate of reintervention observed in New York state’s Medicare population under the age of 65, with the rate of reintervention among all ages and insurance types. Using an indirect matching algorithm, we matched 96% of eligible patients in the VQI EVAR registry to their SPARCS claims (indirect identifiers included facility ID, patients’ year and month of birth, sex, and procedure date). Our findings showed that rates of reintervention for EVAR were similar between Medicare beneficiaries and non-beneficiaries in New York State (19% versus 20%, log-rank p=.199 (Figure 1)[i]). This finding suggests that both Medicare and Medicare patients must be watched closely for reintervention – and that VISION’s registry-linked claims datasets are a valuable step forward towards this important goal. According to Dr. Jesse Columbo, a vascular surgery resident and lead author on this study, “VISION’s device surveillance represents an essential step forward in patient care by allowing sustainable and low-cost access to RWE for patients and providers.”
What’s next? Although VISION has been successful in using registry-linked claims datasets to study device performance and long-term outcomes of Vascular Surgery procedures since 2012, administrative and logistical challenges related to data use agreements and data sharing remain significant barriers to wider adoption of this methodology. As a public-private entity dedicated to scaling up the use of RWE in device surveillance, NESTcc is in a unique position to help foster meaningful discussion among researchers and administrators in order to lay the groundwork for a shared Vision in which patients, providers, payers, and regulators may all benefit from broader use of Real-World Data (RWD).
