Rachel Hess, MD, MS

Rachel Hess Rachel Hess is a Professor of Population Health Sciences and Internal Medicine and the founding Chief of the Division of Health System Innovation and Research (HSIR) program at the University of Utah Schools of the Health Sciences. As a clinician and Health Services Researcher, Dr. Hess brings a unique perspective of translating research into clinical and policy practice. She is the principal investigator of one of the original 11 PCORnet Clinical Data Research Networks, PaTH.

Dr. Hess’s research aims to improve patient-centered outcomes in clinical care. In service of this mission, she seeks to understand determinants of quality of life, including sexual function, and how health-related quality of life affects health and cost outcomes. She has conducted cohort studies in midlife women to examine the impact of menopause on health-related quality of life, including sexual functioning. She is currently following a cohort of adults over 50 to characterize the roles of intrapersonal resources, interpersonal relationships, and individual lifestyle in shaping quality of life across transitions; and the health and healthcare-cost outcomes of quality of life.

Dr. Hess’s implementation work uses health information technology to engage patients in their care. She has examined the impact of providing patients with guideline-based feedback regarding their health behaviors and health-related quality of life on patient activation and behavior change. Dr. Hess has overseen the development and successful implementation of multiple technology-based programs in primary care, including UPMC’s efforts in the electronic collection of patient-reported information as part of routine clinical care throughout the health system. As the director of HSIR, she brings together individuals from across the University of Utah to develop, test, and implement novel approaches that improve health outcomes for the population.

Dr. Hess completed her undergraduate work in mathematics at Washington University, received her medical degree from the University of New Mexico, completed her residency training at Temple University, and completed her general internal medicine and women’s health fellowships at the University of Pittsburgh.
