Pathway to Independence Awards (K99/R00): Funding Dynamics and Prediction of Future National Institutes of Health Research Project Funding.
Academic Article
Overview
abstract
PURPOSE: The authors use the National Institutes of Health (NIH) RePORTER (Research Portfolio Online Reporting Tools) to evaluate funding trends and historic NIH investment increase in the K99 award pathway and examine whether R00 to R01 or R21 achievement time correlates with the future success of an early-stage NIH-funded investigator. METHOD: All K99 awards and funding data in this study were limited to all clinical departments. The authors identified all researchers and awards through a K99 search from fiscal years (FYs) 2007 to 2022 across all clinical departments and investigated trends in K99 awards and funding from NIH FYs 2007 to 2022. They generated an R00 data set and analyzed the K99 to R00 achievement statistics from FYs 2007 to 2022. The authors aggregated NIH annual data files for FYs 2007 to 2021 to generate a master data file of all R01 and R21 awards. They linked R01 and R21 award data to the researcher previously identified through the K99 search and focused on the connection between K99/R00 awardees and subsequent R01 or R21 awards. RESULTS: From FY 2008 to FY 2022, the NIH K99 budget increased 127.0%, whereas the NIH program-level budget increased 17.3%. A principal investigator's mean funding per year significantly decreased as time from R00 to R01 or R21 increased (P < .001); 7 of 15 comparisons differed significantly (2 at P < .01 and 5 at P < .001). CONCLUSIONS: NIH investment in the K99 award pathway has substantially outpaced the NIH program-level budget increase, and there is a strong association between mean funding per year since the start of the R00 phase and time from R00 to R01 or R21. This analysis may be useful to clinical departments as they evaluate selecting new and retaining current biomedical scientists for independent research positions.
