Society of Interventional Radiology Foundation Funding to National Institutes of Health Funding: Report from the Society of Interventional Radiology Foundation/National Institutes of Health Task Force.

The Society of Interventional Radiology Foundation (SIRF) aims to support interventional radiology (IR) investigators by awarding numerous grants to promote the advancement of scientific knowledge in IR. Over the last 19 years, SIRF has awarded 227 research grants, amounting to more than $4.7 million. To increase the engagement of interventional radiologists and IR scientists with the National Institutes of Health (NIH), SIRF created a SIRF/NIH taskforce in 2020. Over the past couple of years, the task force has been working to assess the return on investment of SIRF grants in terms of NIH funding because this metric is an effective measure of assessing the early success of foundation funding. The objectives of this report are to assess SIRF funding from 2002 to 2020 and investigate the conversion of this funding into NIH grants by the same investigators. During the study period, more than $37.6 million in NIH funds were awarded to SIRF awardees, which shows a return of 8 NIH dollars for every 1 SIRF dollar invested.
