Ultimately, the storm caused more than $160 billion in damage, and the population of New Orleans fell by 29 percent between the fall of 2005 and 2011. Corrections? There are many different conclusions on how many people actually died. Similarly, small numbers of observations (n ≤ 5) in our stratified analyses of race/ethnicity within age groups in St Bernard and Jefferson Parishes limited our ability to assess potential associations between demographic characteristics and mortality. Total loading time: 0.36 The city seemed to have escaped most of the catastrophic wind damage and heavy rain that had been predicted.

In the days following Hurricane Katrina, multiple large hospitals in New Orleans flooded and were reportedly operating without power or sanitation services in extreme heatReference Brinkley5 while ambient temperatures in the greater New Orleans area were ≥90°F (32°C) during the days and weeks following Hurricane Katrina.6 As a result of rapidly deteriorating conditions in the New Orleans hospitals and extreme difficulties in evacuating their existing patients, hospitals in the downtown New Orleans area were reportedly not admitting new patients in the days following the storm.Reference Brinkley5 At least 70 hospital inpatients died in New Orleans hospitals, and an additional 57 storm victims' bodies were recovered from hospitals in the days immediately following the storm, indicating that their storm-related cause of death occurred in the hospital. In New Orleans, where much of the greater metropolitan area is below sea level, federal officials initially believed that the city had “dodged the bullet.” While New Orleans had been spared a direct hit by the intense winds of the storm, the true threat was soon apparent. It is also unknown whether the storm exacerbated preexisting medical conditions enough to lead to death. It is unknown whether these people would have died had the storm occurred or not. Our objectives were to verify, document, and characterize Katrina-related mortality in Louisiana and help identify strategies to reduce mortality in future disasters. Improving mortality reporting timeliness will enable response teams to provide appropriate interventions to these populations and to prepare and implement preventive measures before the next disaster. The final case definition for Katrina-related deaths in this analysis included all of the deaths in the DMORT database that were determined to be Katrina related, all Louisiana death certificates with victim of cataclysmic storm listed as the primary or a contributing cause of death, and out-of-state death certificates for Louisiana residents that were classified as related to Hurricane Katrina. } Copyright © Society for Disaster Medicine and Public Health, Inc. 2008, Hostname: page-component-546c57c664-r9c2h Furthermore, the findings in this report are subject to at least three limitations.

Incorporating DMORT data allowed us to identify 171 victims who were not classified as Katrina related in vital statistics/death certificate data, including 17 victims whom coroners were unable to identify by DNA matching or other methods. Adequate mortality reporting in disaster settings, particularly when infrastructure has been damaged or destroyed, is vital to ensuring timely collection of mortality data. Prior to Hurricane Katrina the public school system of New Orleans was one of the lowest-performing districts in the state of Louisiana. Data on race/ethnicity were missing for 42 victims (4%), age was missing for 22 victims (2%), and sex was missing for 4 victims (<1%). To prevent hurricane-related mortality on this scale from occurring in the future, disaster preparedness efforts must focus on evacuating and caring for older people, including those residing in hospitals, long-term care facilities, and personal residences. Drowning (40%), injury and trauma (25%), and heart conditions (11%) were the major causes of death among Louisiana victims. Hyer, Kathryn "Hurricane Katrina: A Nation Still Unprepared," Page 37.

The majority of Hurricane Katrina--related deaths occurred in Louisiana and Mississippi . First, a universally accepted standard definition of a hurricane-related death has not been established. Deaths Directly Caused by Hurricane Katrina Poppy Markwell (MPH) and Raoult Ratard (MD, MPH) Abstract Objective: Previous studies have used multiple death databases to estimate the death toll of Louisiana residents from Hurricane Katrina; however, these studies did not incorporate autopsy reports as a data source. Of note, only 4 storm victims were Asian, although Asians make up 2% of the Orleans Parish population and 1% of the overall Louisiana population.7 Although Hispanic/Latino and Asian race/ethnic groups appear to have been less affected by storm mortality relative to their proportional population size, victim numbers in these groups are small, limiting statistical interpretation. The majority of hurricane victims lived in Orleans Parish (73%), followed by St Bernard (17%), Jefferson (5%), Plaquemines (1%), and St Tammany Parishes (1%). Our objectives were to verify, document, and characterize Katrina-related mortality in Louisiana and help identify strategies to reduce mortality in future disasters. Forty-nine percent of victims were people 75 years old and older. Race-specific mortality rates were also higher among blacks 55 to 64 years old in St Bernard Parish and 75 years old and older in Jefferson Parish, but results from race- and age-specific stratified analyses in these 2 parishes are limited by small number of observations (n ≤ 5).

Ring in the new year with a Britannica Membership, This article was most recently revised and updated by, https://www.britannica.com/event/Hurricane-Katrina, Science Kids - Fun Science and Technology for Kids! We calculated age-, race-, and sex-specific mortality rates for Orleans, St Bernard, and Jefferson Parishes, where 95% of Katrina victims resided and conducted stratified analyses by parish of residence to compare differences between observed proportions of victim demographic characteristics and expected values based on 2000 US Census data, using Pearson chi square and Fisher exact tests. Thomas, Kali Children and younger adults were underrepresented among storm victims relative to their proportional population size. The clearest association with Katrina in our review of out-of-state death certificates was 1 person whose body was found in the Gulf of Mexico off the Florida coast. Drowning (40%), injury and trauma (25%), and heart conditions (11%) were the major causes of death among Louisiana victims. 2011.

Our total mortality estimate of 986 victims likely represents a lower bound estimate for Katrina mortality in Louisiana. Hayashi, Jennifer All deaths occurring before August 29, 2005 and after October 1, 2005 were reviewed to verify that Hurricane Katrina was listed as a contributing cause of death, and all of the deaths occurring after September 23, 2005 were reviewed to determine whether they were associated with Hurricane Rita, which struck southwest Louisiana on September 24, 2005. Drowning and injury-related deaths occurred predominantly near levee infrastructure breaches. YASUDA, Goro and Hurricane Katrina was the costliest and one of the deadliest hurricanes in the history of the United States.It was the sixth-strongest Atlantic hurricane ever recorded and the third-strongest landfalling U.S. hurricane on record. Chi square and Fisher exact tests assessing differences in proportions of black and white victims within age groups found that blacks were significantly more likely to be storm victims than whites in all age group categories 30 years old and older in Orleans Parish (P < .05). Conclusions: Hurricane Katrina was the deadliest hurricane to strike the US Gulf Coast since 1928. On the morning of August 29, the storm made landfall as a category 4 hurricane at Plaquemines Parish, Louisiana, approximately 45 miles (70 km) southeast of New Orleans.

Future disaster preparedness efforts must focus on evacuating and caring for vulnerable populations, including those in hospitals, long-term care facilities, and personal residences. Czajkowski, Jeffrey Older adults were clearly the most affected population cohort during Hurricane Katrina, particularly people 75 years old and older, who made up 49% of victims in Louisiana, whereas their age cohort represents fewer than 6% of both the greater New Orleans and the overall Louisiana population. TABLE 3 Place of Death or Where Body Was Found (N = 877). The majority of the 446 out-of-state deaths were from chronic medical conditions, primarily heart disease, respiratory disease, and cancer.

Instituting an electronic reporting system for recording death certificates would aid with timely use of data for both government and community preparedness and disaster response efforts.Reference Stephens, Grew and Chin8 Alternately, if existing technological infrastructure is unavailable, active mortality surveillance efforts should be initiated immediately to document deaths in the early stages of rescue and recovery responses, not only to aid with accurate mortality reporting and victim identification but also to mobilize needed resources (eg, body bags, mobile laboratories, morgues) in a timely manner. Hiete, Michael The majority of out-of-state deaths occurred in Texas (221, 50%), followed by Alabama (47, 11%) and Mississippi (43, 10%). Christmas, Colleen 2009. First, the disaster response aftermath of Hurricane Katrina may have limited the ability to precisely document all deaths. Kelley, Crystal L. and We further stratified by race within each age category, where sufficient observations existed, to determine whether there was an age-specific effect of race among victims. Data on race/ethnicity were missing for 42 victims (4%), age was missing for 22 victims (2%), and sex was missing for 4 victims ( 1%). Hurricane Katrina, tropical cyclone that struck the southeastern United States in late August 2005. Data sources included the Hurricane Katrina Disaster Mortuary Operational Response Team (DMORT) database and death certificates collected through Louisiana vital statistics and out-of-state coroners' offices. Projections of a sustained or intensifying cycle of Atlantic Ocean hurricane activity throughout the coming decades9, Reference Trenberth and Shea10 and the unprecedented landfall of 2 category 5 storms (Dean and Felix) during the 2007 hurricane season underscore the critical need for all levels of government to be ready to evacuate and care for vulnerable populations during future storms. Hurricane Katrina Memorial Site View All 906 Memorials for the Hurricane Katrina Site In late August of 2005, Hurricane Katrina swept across Florida before touching land again in the Gulf Coast. Areas east of the Industrial Canal were the first to flood; by the afternoon of August 29, some 20 percent of the city was underwater. Seventeen out-of-state deaths (4%) occurred among Calcasieu Parish residents, likely Hurricane Rita evacuees. However, stratified analyses evaluating the effect of race within age groups revealed that the dominant effect of age on overall storm mortality masked the differential effect of race in most age groups in Orleans Parish, where race-specific mortality rates were on average 2.5 times higher among blacks compared with whites. Kennedy, Emily Buekens, Pierre Fifty-three percent of victims were men; 51% were black; and 42% were white. Many local agencies found themselves unable to respond to the increasingly desperate situation, as their own headquarters and control centres were under 20 feet (6 metres) of water. Out-of-state death certificates of Louisiana residents during the period of August 27 to October 1, 2005, and others that state coroners deemed worth consideration for potential association with Hurricane Katrina were forwarded to the Louisiana coroner's office from coroners' offices in 26 states and the District of Columbia. This data will be updated every 24 hours. Of these, 15 were clearly related to Hurricane Katrina, and 431 were classified as indeterminate because no indication of hurricane association was listed on the death certificate.
