How Well Are Pharmacists Represented in National Institutes of Health R01 Funding to United States Schools of Pharmacy?

Pharmacists are essential healthcare providers but historically are not well represented as principal investigators (PIs) of R01 grants by the United States (US) National Institutes of Health (NIH). Pharmacy organizations have taken steps to provide pharmacists with research training to improve their chances of achieving PI status. We conducted a retrospective cohort study using data from the NIH RePORTER website about R01 grants awarded to PIs affiliated with US Schools of Pharmacy (SOPs) for the fiscal years 2005-2019. Information regarding professional degrees was supplemented using data from the PIs' institutional website profiles and other internet-based sources. Only doctorate degrees obtained within the US were included for clinically related degrees. Data regarding more than one year of funding for the same project, equipment supplements, and diversity supplements were excluded to focus on unique projects in year one of funding. PhDs were the primary unique PIs of R01 grants at US SOPs (>90%). Pharmacist representation as unique PIs increased over the 15 years but was still only 10.1% for the years 2015-2019. There was a higher percentage of female pharmacists as unique PIs than female non-pharmacists. Pharmacists are currently underrepresented as unique PIs for NIH R01 grants. This conclusion is limited by not knowing how many pharmacist R01 applications were submitted.
