Rochester, Minnesota


Colglazier.Jill@mayo.edu Clinical Profile


The research interests of Jill K. Johnstone, M.D., involve improving vascular surgical training and patient safety through the use of effective and reproducible simulation training. With the rapid advancement of technology in medicine, and especially in vascular surgery, making sure that surgical trainees are proficient in the knowledge and skills to use these advancements is critical to delivering safe patient care.

Dr. Johnstone also has research interests involving epidemiologic evaluation of vascular disease to better explore providers' abilities to appropriately diagnose and treat vascular disease.

Focus areas

  • Simulation in vascular surgery training. Simulators offer the ability for trainees to acquire and practice surgical skills and for educators to objectively assess the development and progression of these skills.
  • Epidemiological evaluation of vascular disease. During Dr. Johnstone's fellowship at Mayo Clinic, she was involved with studying vascular disease in Olmsted County with the Rochester Epidemiology Project. This aspect of her research continues today — this resource is used to gain information about epidemiologic trends and natural history data pertaining to vascular diseases.

Significance to patient care

Simulation-based training can be a valuable tool for the education of future physicians. It allows them to gain technical and clinical competence in a safe environment and promotes improved patient care.

Studying vascular diseases from an epidemiological standpoint helps to better the understanding of the causes and patterns of these diseases, in hopes of improving therapeutic interventions and surgical outcomes.
