Heat Related Illness ED Visits Data

This indicator estimates the number and rate of emergency department visits for heat stress. It includes all cases where heat stress is listed as a primary or other diagnosis. These data come from hospital records and may not capture the full range of heat-related illness if exposure to excess heat is not explicitly documented. These data can be used to document changes over place and time, monitor vulnerable areas and populations and evaluate the results of local climate-adaptation strategies.

Our heat-related illness data from emergency department visits include:

  • Health outcome (heat stress)
  • State and county of residence
  • Year of emergency department visit
