Applications for and receipt of external research grants are important indicators of scientific productivity, and ones that the Clinical and Translational Science Awards (CTSA) Program is intended to support.

We investigate the association between the receipt of support services from one CTSA-supported hub and investigator productivity as measured by individual investigator grant submissions and grant awards at a Research I public university over an 8-year period. Negative binomial regression models are used to evaluate associations between individual grant productivity (in 2017, 2018, and 2019) and receipt of support services during the preceding 2 years.

Controlling for prior levels of productivity, service receipt is found to be predictive of both grants submitted and grants awarded to investigators in each model examined. Analyses also found some evidence of faculty rank and race/ethnic differences in the effects of Center for Clinical and Translational Science (CCTS) service use on subsequent grant productivity.

Further work is needed to understand the relationship between clinical and translational services and other measures of productivity.
