A Ten-Year Analysis of Recent National Institutes of Health Funding for Anesthesiology Research in United States Medical Schools

Abstract

The characteristics of recent National Institutes of Health (NIH) grant funding to anesthesiology researchers in United States (US) medical schools have not been systematically quantified. NIH funding to cardiac anesthesiologists has also not been estimated. The author conducted an internet-based analysis of NIH awards to anesthesiology researchers from 2011-2020 to identify the types, duration of funding, and amount of grants, and the terminal degree(s), faculty rank, gender, board certification status, and type of appointment of the grant recipients including those with an interest in cardiac anesthesiology. Observational study. Internet analysis. NIH grants recipients. None. NIH grant recipients affiliated with anesthesiology departments were identified from the Blue Ridge Institute for Medical Research website. The number of grants, years of support, and total amount of funding were quantified for research project grants (R series), mentored career development awards (K series), and other grants (U and P series) using NIH Research Portfolio Online Reporting Tools. The terminal degree(s), faculty rank, gender, and type of appointment of grant recipients were identified using department web pages. American Board of Anesthesiology (ABA) certification, National Board of Echocardiography Advanced Perioperative Transesophageal Echocardiography (TEE) certification, and previous or current Foundation for Anesthesia Education and Research (FAER) awards to NIH grant recipients were obtained from each organization's website. A total of 532 researchers received 1250 grants with 3844 cumulative years of funding amounting to $1,676,482,440. R series grants accounted for three-quarters of all funding. PhDs were awarded more than one-half of NIH grants. MDs had lower median numbers of projects, R01 grants, and total R series grants than their colleagues with PhD or MD PhD degrees, but MDs received more K awards. One hundred ninety-eight MD and MD PhD NIH grant recipients were ABA diplomates. These physician-scientists received 26.0% and 53.1% of R and K series grants, respectively. Thirty physician-scientists also held TEE certification; these individuals with an interest in cardiac anesthesiology were awarded 4.8% of all NIH grants. Full Professors were awarded more than three-quarters of R grants and amassed more than $1.3 billion in funding, whereas assistant and associate professors received the majority of K series grants. Male investigators received greater median R grants but fewer median K awards than female researchers. One hundred-fifteen previous or current holders of FAER grants were identified; these individuals earned a total of 240 NIH awards totaling $357.7 million. PhDs, Professors, and male researchers receive the majority of R01 and other R series grants to anesthesiology departments at US medical schools. Physician-scientists, including those interested in cardiac anesthesiology, are awarded a minority of R series grants. FAER continues to provide an important stimulus for subsequent NIH funding of physician-scientists in anesthesiology.
