Westyn Branch-Elliman


I am a physician investigator who focuses on optimizing healthcare resource utilization and expanding infection prevention programs beyond traditional boundaries. My research projects include epidemiologic and economic evaluations of postpartum breast infections, comparative and cost-effectiveness evaluations of preventions designed to reduce healthcare-associated infections (HAI), and development of novel electronic tools for improved HAI detection. The majority of my time is dedicated to clinical research. I also see patients and teach medical students, residents and infectious diseases fellows. In my previous role as the Medical Director of Infection Prevention at the Eastern Colorado VA Healthcare System, I dedicated significant effort to administrative responsibilities, including healthcare epidemiology and antimicrobial stewardship.
