Academic Bio

Dr. Guilherme Del Fiol earned his PhD in Biomedical Informatics from the University of Utah. He earned his MD at the University of Sao Paulo, Brazil and his MS in Computer Science at Catholic University of Parana, Brazil. He is an Assistant Professor in the University of Utah’s Department of Biomedical Informatics since 2011. Prior to the University of Utah, Dr. Del Fiol held positions at the Clinical Knowledge Management team at Intermountain Healthcare and at the Duke Community and Family Medicine Department. Since 2008, he has served as one of the co-chairs of the Clinical Decision Support Work Group at HL7. He is the lead author for the HL7 Infobutton Standard and the project lead for OpenInfobutton, an open source suite of infobutton tools and Web services, which is in production use at several healthcare organizations throughout the United States, including Intermountain Healthcare, Duke University, and the Veterans Health Administration (VHA).

“Health informatics combines the two areas that appeal to me the most, health care and technology. I feel this combination provides me with greater potential to improve the quality of health care than through direct patient care. It is rewarding knowing that my research work has practical and direct implications in the daily routine of clinicians and ultimately in people’s health. This is a major motivation for me to come to work every day.”

Research Statement

I am interested in the design, development, evaluation and dissemination of clinical informatics and clinical decision support (CDS) interventions to improve the quality, safety, and value of health care. I am especially interested in the integration of medical evidence resources with electronic health record (EHR) systems to help clinicians and patients find answers to clinical questions. I am also interested in the development and implementation of health IT standards to promote wide dissemination of CDS interventions across health care organizations and EHR platforms.
