Abstract This report describes the medical response, action plan, and after-action summary adopted by the Louisiana State University (LSU) New Orleans - Emergency Medicine (EM) Residency Program in response to Hurricane Ida which occurred in New Orleans, Louisiana (USA) late August through early September 2021. New Orleans has an estimated 385,000 people within the 350 square miles surrounding the metropolitan area, with greater than one million residents in all of Louisiana. In the two-week time span during and following the event, residents, nurses, attendings, ancillary staff, and Emergency Medical Services (EMS) managed a substantial intensification in daily EM activities due to a substantial lack of resources (ie, food, electricity, water, housing, medications, oxygen, and primary care). This report outlines the redistribution of emergency department (ED) residents within the primary clinical site, University Medical Center New Orleans (UMCNO); describes the daily communication flow from the chief residents and program director; describes the daily EM response; describes the pre- and post-action plans based on those efforts during hurricane operations; and summarizes the obtained information.
