Preparing for Extreme Heat Events: Practices in Identifying Mortality.
Health Security
|April 16, 2016
Summary
Deaths from extreme heat are undercounted, especially among minority groups. Accurate identification of heat-related deaths is crucial for effective urban heat risk management and public health preparedness.
Area of Science:
- Environmental science and public health
- Urban climate adaptation strategies
Background:
- Climate change exacerbates extreme heat events, posing significant risks to urban populations.
- Under-identification and misclassification of heat-related mortality obscure the true public health burden.
Purpose of the Study:
- To investigate the under-identification of deaths during heat waves.
- To compare characteristics of officially heat-related deaths (oHDs) versus possibly heat-related deaths (pHDs) in New York City.
- To improve the assessment of urban heat risk.
Main Methods:
- Analysis of New York City death records from 2010 to 2012.
- Comparative analysis of demographic and evidential characteristics between oHDs and pHDs.
- Evaluation of official criteria for classifying heat wave exposure deaths.
Main Results:
- Officially identified heat-related deaths (oHDs) disproportionately affected Black individuals and younger populations.
- Evidence substantiating oHDs, by official New York City criteria, was frequently lacking.
- Significant discrepancies were observed between officially recorded and potentially heat-attributable deaths.
Conclusions:
- Heat wave mortality is inaccurately recorded, leading to a misestimation of heat risk.
- Enhanced training for evidence collection and interpretation is needed for accurate mortality assessment.
- Improved data accuracy is vital for effective public health preparedness and intervention strategies for extreme heat events.

The signs and symptoms of fever include hot and dry skin, flushed face, thirst, muscle aches, anorexia, headache, tachycardia, tachypnea, and fatigue. Elevated body temperature is reduced using two methods: pharmacological and nonpharmacological. Proper identification and treatment of the root cause of a fever is of utmost importance.

01:29Decreased Body Temperature
1.2K
A decreased body temperature can occur in patients with hypothermia and frostbite. Heat loss with extended cold exposure overpowers the body's ability to create heat, resulting in hypothermia. Core temperature readings help classify hypothermia. Mild hypothermia is temperatures between 32 °C (89.6 °F) and 35°C (95 °F) and is caused by impaired thermoregulation. Moderate hypothermia is temperatures between 28 C (82.4 °F) and 32 °C (89.6 °F) caused by...

Here is a stepwise guide to assessing the body temperature at the temporal artery using a temporal artery thermometer
Step 1: Perform hand hygiene and don a fresh pair of gloves to prevent cross-infection and ensure patient safety.
Step 2: Explain the procedure to the patient to establish trust. Clear communication establishes trust with the patient, ensures they understand what to expect, promotes cooperation, and enhances comfort during the procedure.

Hyperthermia occurs when the body's temperature becomes unusually high, often due to heat exposure, intense physical activity, or certain illnesses. This condition can create a dangerous cycle where elevated body temperature increases the metabolic rate, generating more heat and potentially leading to organ failure and brain damage. A severe form of hyperthermia, called heat stroke, can raise body temperature to life-threatening levels. Fever, on the other hand, is a controlled form of...

Following these guidelines can help nurses accurately measure vital signs, assess changes in patient conditions, and provide timely treatment when necessary. Adhering closely to the guidelines ensures the accuracy and reliability of the results.
Before taking a patient's vital signs, a nurse would consider and assess the patient's comfort level and ensure appropriate equipment is available.
