Impact of co-investigators on pharmacy resident research publication

Paul M. Stranges, Scott M. Vouri


Objective: To explore influences of co-investigators on the successful publication of a pharmacy residency project.

Methods: We analyzed published and non-published research presented at a regional pharmacy conference. Abstracts were matched 1:1 based on state and abstract year. We assessed university affiliation, number, degree, and H-Index of co-investigators on the abstract. Descriptive and inferential analyses were used to identify variables associated with resident publication.

Results: University-affiliated programs (p=0.015), highest H-Index of a non-physician co-investigator (p=0.002), and positive H-Index (≥1) of a non-physician co-investigator (p=0.017) were significant predictors of resident publication on univariate analyses. There were no differences in the number of co-investigators (p=0.051), projects with physician co-investigators (p=1.000), or projects with Doctor of Philosophy (PhD) or Master of Science (MS) co-investigators (p=0.536) between published and non-published projects. Multivariate analysis found that the highest H-index of non-physician co-investigator remained significant as a predictor to resident publication (odds ratio (OR) 1.09, 95% Confidence Interval (CI) 1.01-1.17).

Conclusions: The quality of co-investigators, as measured by an increasing H-Index, is associated with the successful publication of residency projects. More emphasis may need to be placed on resident research co-investigator selection and training to prepare pharmacy residents for research and scholarly activity.
