Author Disambiguation in PubMed: Evidence on the Precision and Recall of Author-ity among NIH-Funded Scientists.

ABSTRACT: We examined the usefulness (precision) and completeness (recall) of the Author-ity author disambiguation for PubMed articles by associating articles with scientists funded by the National Institutes of Health (NIH). In doing so, we exploited established unique identifiers-Principal Investigator (PI) IDs-that the NIH assigns to funded scientists. Analyzing a set of 36,987 NIH scientists who received their first R01 grant between 1985 and 2009, we identified 355,921 articles appearing in PubMed that would allow us to evaluate the precision and recall of the Author-ity disambiguation. We found that Author-ity identified the NIH scientists with 99.51% precision across the articles. It had a corresponding recall of 99.64%. Precision and recall, moreover, appeared stable across common and uncommon last names, across ethnic backgrounds, and across levels of scientist productivity.

Project description:Background and objectivesAlthough US physician-scientists have made enormous contributions to biomedical research, this workforce is thought to be getting smaller. However, among kidney researchers, changes have not been fully quantified.Design, setting, participants, & measurementsWe mined National Institutes of Health RePORTER to explore demographic changes of early-career and established physician and nonphysician principal investigators doing kidney-focused research. We searched for National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK)-funded K series and R01 awards focused on the kidney that were active between 1990 and 2020 and determined if their emphasis was basic or clinical science. We then used public databases available on the internet to determine if these funded investigators were physicians or nonphysicians, the year in which they received either their MD (physicians) or their terminal graduate degree (nonphysicians), their sex, and whether they received their terminal degree from a US or international institution.ResultsKidney-focused R01-funded principal investigators are aging, particularly among physicians. Moreover, the relative representation of physicians among both early-career and established principal investigators is falling, particularly among those doing basic science research. In contrast, the number and relative representation of nonphysician-scientists are increasing. There is also greater representation of women and international graduates among physician and nonphysician R01-funded, kidney-focused NIDDK investigators. However, although there are greater numbers of women physician principal investigators doing both basic as well as clinical research, women physician principal investigators are increasingly more likely to do clinical rather than basic science research.ConclusionsThe physician-scientist workforce is increasingly made up of women and international medical graduates. However, the physician-scientist workforce is older and represents a smaller proportion of all principal investigators, particularly among those doing basic science research.
