Our publications 

At CATALYST, our faculty and staff are always hard at work on a number of projects related to team science, analytics, and systems thinking. Our research has been published in a variety of journals, and it is regularly cited in other scholarly work.

Among our most recent publications, appearing in the American Journal of Infection Control, is "Identifying management practices for promoting infection prevention: Perspectives on strategic communication" by Ann Scheck McAlearney, ScD, MS; Sarah MacEwan, PhD; Megan Gregory, PhD; Lindsey Sova, MPH; Courtney Hebert, MD, MS; and Alice Gaughan, MS. The article details an extensive study that involved interviews of 188 administrative and clinical leaders across 18 U.S. hospitals regarding the management practices employed to help prevent healthcare-associated infections (HAIs). By identifying and describing these practices, the authors offer insight into how strategic communication can support improvement.

CATALYST is being created as a means of fostering a collaborative culture of research while providing the environment that supports success.

Our vision

To develop the infrastructure necessary to ensure extramural funding, improve the quality of scholarship, develop faculty in the area of health services and implementation science research, and increase the educational capacity of the institution while serving to extend the research, education and clinical enterprises of The Ohio State University College of Medicine.

Our values

  • Success through collaboration and sustained productivity
  • Leadership with integrity and personal accountability
  • Respect of diversity of people and ideas through openness and mutual trust
  • Innovation through creativity
  • Passion in what we do by engaging with each other through kindness and fun

Our aims

Guided by its mission, CATALYST aims to:
  • Provide a shared HSR infrastructure to provide expedited access to highly trained research support staff and data
  • Promote a team science-based, collaborative environment in which faculty and postdoctoral researchers are highly mentored by successful HSR faculty to be highly productive (both in papers and grants)
  • Enhance the quality and quantity of published research in HSR and implementation science
  • Identify opportunities for extending the educational mission of the College of Medicine
  • Improve the success rate of applications for funding through initial scoping, review and critical assessment so as to improve submitted proposals
