Abstract
OBJECTIVES Obtaining National Institutes of Health funding for heart transplant research is becoming increasingly difficult, especially for surgeons. We sought to determine the impact of National Institutes of Health-funded cardiac transplantation research over the past 30 years. METHODS National Institutes of Health Research Portfolio Online Reporting Tools Expenditures and Results was queried for R01s using 10 heart transplant-related terms. Principal Investigator, total grant funding amount, number of publications, and citations of manuscripts were collected. A citation-based Grant Impact Metric was assigned to each grant: sum of citations for each manuscript normalized by the funding of the respective grant (per $100K). The department and background degree(s) (MD, PhD, MD/PhD) for each funded Principal Investigator were identified from institutional faculty profiles. RESULTS A total of 321 cardiac transplantation R01s totaling $723 million and resulting in 6513 publications were analyzed. Surgery departments received more grants and more funding dollars to study cardiac transplantation than any other department (n = 115, $249 million; Medicine: n = 93, $208 million; Pathology: 26, $55 million). Surgeons performed equally well compared with all other Principal Investigators with respect to Grant Impact Metric (15.1 vs 20.6; P = .19) and publications per $1 million (7.5 vs 6.8; P = .75). Finally, all physician-scientists (MDs) have a significantly higher Grant Impact Metric compared with nonclinician researchers (non-MDs) (22.3 vs 16.3; P = .028). CONCLUSIONS Surgeon-scientists are equally productive and impactful compared with nonsurgeons despite decreasing funding rates at the National Institutes of Health and greater pressure from administrators to increase clinical productivity.
