HOBI Faculty Member Receives Award for Outstanding Research

Yi Guo, Ph.D.Yi Guo, Ph.D., an assistant professor in the Department of Health Outcomes & Biomedical Informatics (HOBI), recently received the UF Health Shands Rose Rivers Chrysalis Award from the College of Nursing for outstanding research.

The Award was given to Guo for his study on in-hospital mortality rates pertaining to length of stay in the emergency department (ED) among patients with stroke caused by cerebral hemorrhage.

“Dr. Yoon and I are honored to have received this recognition for our study,” Guo said.

Guo collaborated on the study with Saun-Joo Yoon Ph.D., R.N. and Nicolle Davis, a Ph.D., student of Dr. Yoon’s, in the UF College of Nursing. The researchers analyzed administrative claims data and health records of 4,698 patients to identify factors associated with ED length of stay, including health system operations and patient characteristics such as age, sex and race.

The ED is often the first line of defense for patients seeking medical care for spontaneous intracerebral hemorrhage (ICH), the second most common type of stroke.

“These forms of stroke require rapid identification and focused management,” Guo said. “However, one-third of patients who arrive in the ED experience significant worsening of the stroke within the first three hours of developing symptoms, while they are being treated in the ED.”

The researchers hope that identifying some of the factors that contribute to these problems will lead to improved care and better health outcomes for stroke patients.

Guo is an outcomes researcher with a strong quantitative background. He has extensive experience applying complex statistical and machine learning models to examine disparity in a wide range of health outcomes. His current research focuses on integrating heterogeneous data from multiple levels for modeling health disparity, building and evaluating health risk prediction models, and developing and testing eHealth interventions.
