*Blanchard note on sources: Ours, by necessity, is a compilation from several sources.

 

(1) Centers for Disease Control and Prevention WONDER database underlying and multiple cause of death searches for T67 and X30. These suffer, however, from the fact that the CDC does not show deaths in Census or DHS Regions or States or Counties if the loss is less than ten. These deaths, therefore are unknown to us unless found in another source.

 

(2) The National Climatic Data Center, NOAA. Internet searches via the Storm Events Database can be queried. For “heat,” one has to do two searches – one for “excessive heat” and one for “heat.” Frequently the entries in one seem similar to ones in the other. The NCDC also publishes Storm Data, a monthly, electronically accessible.

 

(3) The National Weather Service, another NOAA entity, publishes tables on heat fatalities. Their figures differ from NCDC figures. None of the NOAA sources is comprehensive for two subsets – children in vehicles and workers, though one can find references to each. Both generally show fewer deaths than CDC Wonder in that primarily what is noted are “direct” deaths attributable to high natural heat (Underlying Cause of Death in CDC parlance). This is the case even for CDC Wonder searches for excessive heat as an underlying cause of death.

 

(4) For coverage of children dying in cars due to excessive heat exposure we rely on Jan Null and KidsAndCars.org).

 

(5) OSHA provides more comprehensive coverage of worker heat-related fatalities

 

(6) Newspaper archives, particularly when looking for end-of-heat-season statements by State Offices of Chief Medical Examiners. Frequently their numbers differ markedly (upward) from CDC, NCDC or NWS figures.

 

(7) State, County or local Public Heath or Vital Statistic entities (again higher numbers generally noted than can be found in CDC Wonder. 

 

Note on ICDC Codes used in CDC Wonder Online Database above and below: We use the T67 and X30 codes described below. We use them independently in the “Census Region,” “HHS Region” and “State” locations in the search page. There are two “boxes” to search – ?Underlying Cause of Death” and “Multiple Causes of Death” – the higher numbers are to be found when using the Multiple Causes of Death option for “Census Region.”)

 

T67    Effects of heat and light

 

T67.0 (Heatstroke and sunstroke);

T67.1 (Heat syncope); heat syncope [fainting]; factors include dehydration and lack of acclimatization.

T67.2 (Heat cramp);

T67.3 (Heat exhaustion, anhydrotic);                        [Note: T67 codes are in the class of “multiple

T67.4 (Heat exhaustion due to salt depletion);           cause of death,” meaning, usually, that heat

T67.5 (Heat exhaustion, unspecified);                        contributed to or combined with another

T67.6 (Heat fatigue, transient);                                  cause of death – such as a heart condition.]

T67.7 (Heat oedema);

T67.8 (Other effects of heat and light);

T67.9 (Effect of heat and light, unspecified)

 

X30 Exposure to excessive natural heat; hyperthermia. [Underlying (or primary) cause of death.]

Narrative Information

 

NWS: “In 2004, only 6 lives were lost to excessive heat, down dramatically from 36 in 2002 and even more dramatically from the 10-year average for heat related fatalities: 237. In 2004, 3 fatalities occurred in permanent homes, 2 outside and 1 in a vehicle. Texas was hardest hit with 3 deaths, followed by Missouri, Tennessee and Pennsylvania with 1 each. In a divergence from past years, losses were even between those 40-49 and senior aged 70-79. Seniors typically are the hardest hit by extreme heat. Deaths were split evenly between men and women.” (National Weather Service, NOAA. 2004 Heat Related Fatalities.)

 

On Heat:

 

CDC. “Heat-Related Deaths – [U.S.], 1999-2003,” MMWR, V55, N29, 7-28-2006, 796-798:

“Heat-related illnesses (e.g., heat cramps, heat exhaustion, heat syncope, or heatstroke) can occur when high ambient temperatures overcome the body’s natural ability to dissipate heat. Older adults, young children, and persons with chronic medical conditions are particularly susceptible to these illnesses and are at high risk for heat-related mortality. Previous analyses of the risk factors associated with heat-related deaths have been based on the underlying cause entered on the death certificate. The analysis revealed that including these deaths increased the number of heat-related deaths by 54% and suggested that the number of heat-related deaths is underestimated.

 

“CDC uses information from death certificates categorized by codes from the International Classification of Diseases to estimate national mortality trends. These data, collected and submitted by states, were used to determine the number of deaths in the United States during 1999–2003 that had exposure to excessive natural heat§ recorded as the underlying cause (code X30 from ICD, tenth revision [ICD-10]), hyperthermia recorded as a contributing factor (ICD-10 code T67) (6), or both….

 

Editorial Note: In this analysis, the inclusion of hyperthermia as a contributing cause of death increased by 54% the total number of heat-related deaths during 1999–2003 that would have been counted through inclusion of a heat-related underlying cause alone. Because heat-related illnesses can exacerbate existing medical conditions and death from heat exposure can be preceded by various symptoms, heat-related deaths can be difficult to identify when illness onset or death is not witnessed by a clinician. In addition, the criteria used to determine heat-related causes of death vary among states. This can lead to underreporting heat-related deaths or to reporting heat as a factor contributing to death rather than the underlying cause.

 

“Continued exposure to excessive heat can lead to hyperthermia or death. Of the heat-related illnesses, heat exhaustion and heatstroke are the most serious. Heat exhaustion is characterized by muscle cramps, fatigue, headache, nausea or vomiting, and dizziness or fainting. The skin is often cool and moist, indicating that the body’s mechanism for cooling itself (i.e., sweating) is still functioning. The pulse rate is typically fast and weak, and breathing is rapid and shallow. If untreated, heat exhaustion can progress to heatstroke. Heatstroke is a serious, life-threatening condition characterized by a high body temperature (>103ºF [>39.4ºC]); red, hot, and dry skin (no sweating); rapid, strong pulse; throbbing headache; dizziness; nausea; confusion; and unconsciousness. Symptoms can progress to encephalopathy, liver and kidney failure, coagulopathy, and multiple organ system dysfunction. Prompt treatment of heat-related illnesses with aggressive fluid replacement and cooling of core body temperature is critical to reducing morbidity and mortality.

 

“Many heat-related deaths, regardless of whether they are associated with chronic medical conditions, are preventable. During periods of extreme heat, heat-related illnesses can be prevented by avoiding strenuous outdoor activities, drinking adequate amounts of fluid, avoiding alcohol consumption, wearing lightweight clothing, and using air-conditioning. Groups at high risk include young children, persons aged >65 years, persons who do strenuous activities outdoors, and persons with chronic (particularly cardiovascular) medical conditions.”

 

EPA (Environmental Protection Agency) on Heat-Related Deaths (11-21-2023):

 

“When people are exposed to extreme heat, they can suffer from potentially deadly illnesses, such as heat exhaustion and heat stroke. Hot temperatures can also contribute to deaths from heart attacks, strokes, and other forms of cardiovascular disease. Heat is the leading weather-related killer in the United States, even though most heat-related deaths are preventable through outreach and intervention (see EPA’s Excessive Heat Events Guidebook at: www.epa.gov/heat-islands/excessive-heat-events-guidebook).

 

Unusually hot summer temperatures have become more common across the contiguous 48 states in recent decades…extreme heat events (heat waves) have become more frequent and intense… and these trends are expected to continue. As a result, the risk of heat-related deaths and illness is also expected to increase.[70] The “urban heat island” effect accentuates the problem by causing even higher temperatures in densely developed urban areas. Reductions in cold-related deaths are projected to be smaller than increases in heat-related deaths in most regions. Death rates can also change, however, as people acclimate to higher temperatures and as communities strengthen their heat response plans and take other steps to continue to adapt.

 

“Certain population groups already face higher risks of heat-related death, and increases in summertime temperature variability will increase that risk. The population of adults aged 65 and older, which is expected to continue to grow, has a higher-than-average risk of heat-related death. Children are particularly vulnerable to heat-related illness and death, as their bodies are less able to adapt to heat than adults, and they must rely on others to help keep them safe. People with certain diseases, such as cardiovascular and respiratory illnesses, are especially vulnerable to excessive heat exposure, as are the economically disadvantaged. Data also suggest a higher risk among non-Hispanic Blacks.”

 

Trent, CA Dept. of Health Services on Heat-Related (HR) Illness: “HR illness is described according to three stages of increasing severity:

 

  1. Heat cramps. Mild and easy to treat, this level involves fevers generally under 102 degrees Fahrenheit.
  2. Heat exhaustion: Involves fevers over 102 degrees Fahrenheit, often with vomiting, diarrhea, and fatigue.
  3. Heat stroke: A severe and life-threatening failure of body’s ability to cool (e.g., sweating ceases), with fevers over 104 degrees Fahrenheit. Heat stroke can result in organ and neurologic damage and lead quickly to death.” (p. 3)

 

Exertional heat stroke tends to occur among younger (under 50 years old), healthier persons who develop heat stroke after strenuous activity and inadequate hydration. The result is dehydration and electrolyte imbalance. Exposures may involve work or recreational activities outdoors.

 

Classic heat stroke tends to occur among persons who are older (over 50 years old), frail, and with chronic diseases. They may take medications, have psychological or cognitive problems, and live alone. They are assumed to have a compromised thermoregulatory response due to their age, illnesses, and medications. They generally are not in an air conditioned space when discovered with heat stroke symptoms or deceased.” (p. 5)

 

(Trent, Roger B., Ph.D. (CA Dept. of Health Services). Review of July 2006 Heat Wave Related Fatalities in California. Sacramento, CA: Epidemiology and Prevention for Injury Control Branch, California Department of Health Services, May 2007.)

 

Associated Press (Anita Snow and Kendria Lafleur), Mishmash of how US heat deaths are counted complicates efforts to keep people safe as Earth warms.” 8-13-2023:

“….Even when it seems obvious that extreme heat was a factor, death certificates don’t always reflect the role it played. Experts say a mishmash of ways more than 3,000 counties calculate heat deaths means we don’t really know how many people die in the U.S. each year because of high temperatures in an ever warming world.

 

“That imprecision harms efforts to better protect people from extreme heat because officials who set policies and fund programs can’t get the financial and other support needed to make a difference….Currently, about the only consistency in counting heat deaths in the U.S. is that  officials and climate specialists acknowledge fatalities are grossly undercounted…

 

“ ‘It’s frustrating that for 90 years public health officials in the United States have not had a good picture of heat-related mortality because we have such a bad data system,’ said Dr. David Jones, a Harvard Medical School professor who also teaches in the epidemiology department at the Harvard T.H. Chan School of Public Health.

 

“There is no uniformity among who does the counting across U.S. jurisdictions. Death investigations in some places might be carried out by a medical examiner, typically a physician trained in forensic pathology. In other locales, the coroner could be an elected sheriff, such as the one in Orange County, California. In some small counties in Texas, a justice of peace might determine cause of death. Utah and Massachusetts are among states that do not track heat-related deaths where exposure to extreme heat was a secondary factor.

 

“The CDC, which is often several years behind in reporting, draws information on heat deaths from death certificate information included in local, state, tribal and territorial databases. The CDC said in a statement that coroners and others who fill out death certificates ‘are encouraged to report all causes of death,’ but they may not always associate those contributing causes to an extreme heat exposure death and include the diagnostic codes for heat illnesses.

 

“Hess, the Arizona coroner [Pima County medical examiner], said determining environmental heat was a factor in someone’s death is difficult and can take weeks or even months of investigation including toxicological tests. ‘If someone was shot in the head, it’s pretty obvious what happened there,’ Hess said. ‘But when you find a body in a hot apartment 48 hours after they died, there is a lot of ambiguity.’ Hess noted that Pima County this year began including heat-related deaths in its tally of environmental heat fatalities….”

[1] Notes that “Deaths attributed to exposure to natural heat, as the underlying and contributing causes of death, are coded as X30 and T67, according to the International Classification of Diseases, 10th Revision. Also notes that death data relates to “U.S. residents only.” We use as the number of heat-related deaths for the year even though we have not been able to document all these deaths individually. We view this source as authoritative.

[2] CDC-Wonder results relate only to cases where hyperthermia was coded X30 as primary (direct) cause of death by a medical examiner on a death certificate. “Heat-related” deaths are viewed as those where heat was an indirect or contributing cause of death, and are not included. Even with what we would view as a direct X30 heat death we know that sometimes such deaths are coded as something else – such as a dehydration in the case of a child left in a hot car, or heart-failure brought on by a heat stroke, and thus do not show up in a exposure to excessive heat query. Also, CDC WONDER suppresses (does not show) fatality numbers in a State where the loss of life is less than 10.

[47] Null includes in her listing of hyperthermia deaths of children in vehicles for 2004. The news article on her website notes that death could have been due to suffocation.

[48] While we show only one death, on Long Island, that is heat-related, for 2004, we choose to show the results of a study by the Centers for Disease Control and Prevention which notes that in New York City alone during 2000-2011, an average of “13 persons died from heat stroke.” This report goes on to note that this could well be an under-representation of heat deaths: “In 2006, 100 excess deaths from natural causes in NYC were attributed to a severe heat wave, based on typical summer mortality rates from a statistical model.” This is far more than the 70 deaths recorded for two heat waves in 2006 and 2011 in NYC, combined. Thus if one considers excess deaths, as well as heat-related deaths not ruled as “heat stroke,” as well as the fact that this discussion is only of NYC, not NY state, then the use of the average of 13 deaths for all of NY for 2004 is neither arbitrary nor unreasonable in our view.
