Research Interests

Dr. Patterson is a nationally registered paramedic (NRP) and senior scientist in the Department of Emergency Medicine at Carolinas Medical Center, part of Carolinas HealthCare System. He has completed two fellowships. In 2007 he completed a fellowship in health services research at UNC-Chapel Hill's Cecil G. Sheps Center for Health Services Research with support from an AHRQ T-32 post-doctoral fellowship. In 2008, he completed a fellowship in patient safety at the University of Pittsburgh, Department of Emergency Medicine with support from the Society for Academic Emergency Medicine and Emergency Medicine Patient Safety Foundation. From 2009 to 2014 he was supported by a KL2/K12 career training grant from the National Institutes of Health (NIH), National Center for Research Resources (NCRR).

Dr. Patterson's research interest include patient safety, worker/clinician safety, and organizational safety culture in the emergency medicine setting. Topics of particular interest include shift work, workplace fatigue and sleep health of clinicians, safety culture, teamwork amongst clinicians and team configuration/familiarity, adverse events and medical error for patients and clinicians, workplace injury. He has experience and expertise in developing and testing the reliability and validity of measurement tools for safety outcomes and factors that threaten safety. Dr. Patterson's recent research has focused on the development and testing of novel measurement tools for real-time assessment and intervention of clinician sleep, fatigue, and safety in the emergency care setting.
