Gajic.Ognjen@mayo.edu Clinical Profile


The research interests of Ognjen Gajic, M.D., center on the epidemiology, pathophysiology and management of specific critical care syndromes such as acute lung injury and multiorgan dysfunction. He conducts research with a particular focus on health care delivery, simulation modeling and informatics.

Focus areas

  • METRIC-ePM. Dr. Gajic's Multidisciplinary Epidemiology and Translational Research in Intensive Care, Emergency, and Perioperative Medicine (METRIC-ePM) Laboratory at Mayo Clinic continuously evaluates the clinical course and outcomes of patients with critical illnesses, with a goal of identifying and implementing best practices and improving the quality of care and outcomes. Sophisticated data retrieval and analysis techniques, clinical informatics, simulation modeling, and implementation science enable Dr. Gajic and his colleagues to search for new knowledge regarding disease mechanisms, the response of the human body to acute illness or injury, and the most effective treatment approaches. Notable international efforts led by Dr. Gajic's research group include Checklist for Early Recognition and Treatment of Acute Illness and iNjury (CERTAIN) and Viral Infection and Respiratory Illness Universal Study (VIRUS).

Significance to patient care

Coordinated improvements in clinical practice have led to improved outcomes for patients who are critically ill or injured. Intelligent environment, education and decision-support applications developed by Dr. Gajic and his team are being used in hospitals around the world. Clinical studies have shown process improvements, decreases in adverse events and improved patient outcomes.
