Allen Hsiao MD, FAAP, is Professor of Pediatrics and of Emergency Medicine at the Yale School of Medicine and serves as the Chief Medical Information Officer (CMIO) for the Yale School of Medicine and Yale New Haven Health System. He received his BA in Biomedical Ethics and MD from Brown University, then completed residency training in Pediatrics at Yale before completing fellowships and board certifications in Pediatric Emergency Medicine and Medical Informatics. He has served on numerous medical informatics-related committees for the Hospital and University, as well as nationally for groups such as the American Academy of Pediatrics, Health Information Management Systems Society, and the National Association of Children’s Hospitals and Related Institutions.

Dr. Hsiao has published many articles in the pediatric and healthcare informatics literature and regularly presents nationally and internationally on leveraging informatics and the electronic health record (EHR) to support research, optimize systems, and improve transitions of care. He has also served as primary investigator or co-investigator on several NIH and AHRQ-funded grants examining the ways health information technology can impact and improve healthcare. Allen also co-directs the Informatics Core for Yale’s Clinical Translational Science Award (CTSA) from the National Institutes of Health. In this capacity, he works closely with the Yale Center for Clinical Investigations leadership to equip investigators with the tools and information needed for translational and clinical research. This includes leveraging the industry-leading functionalities of the EHR (Epic) system and the clinical trials management system (OnCore) for investigators and patient focused research.

As the CMIO, Dr. Hsiao leads the medical informatics and data and analytics teams for the School and System, including an experienced group of physician informaticians and the Joint Data and Analytics Team (JDAT). He and the informaticians are responsible for medical leadership of the electronic health record system (EHR) and supporting information technology systems to provide the functionality, clinical decision support, and innovation needed to deliver the best healthcare possible. His Joint Data and Analytics Team includes the database administrators, data architects, and a team of over 50 analysts that provide the reporting and analytics for the System and the School, supporting operational, clinical, and research reporting and data needs and is led by a talented Chief Data & Analytics Officer. Current priorities for Allen and team include supporting COVID-19 informatics needs, predictive analytics, strategies to address growing physician burnout, patient engagement, population health, and supporting genomic medicine.
