Inpatient Hospitalizations due to Heat-Related Illness by County, May through September, New Jersey, 2018-2022
Why Is This Important?
The relationship between extreme heat and increased daily morbidity is well established. This indicator captures inpatient hospital admissions for heat-related illness or hyperthermia.
Definition
Inpatient hospital discharges for heat-related illnesses for a defined population in a specified time interval. Cases were selected using the following ICD-9 codes through September 2015: 992.0 - 992.9, E900.0, or E900.9 as a primary diagnosis, injury cause, or other diagnosis for occurrences during the months of May through September. Cases were excluded if a man-made source of heat (ICD-9 E900.1) was listed. Beginning October 2015, heat-related illness was defined by ICD-10 codes T67, X30, and X32 (exclusion W92).

Data Issues
'''Overall Discharge Volume in 2020: ''' Hospital claim volume for the 2020 calendar year was markedly lower (19.9%) than for 2019, mostly due to the COVID-19 pandemic. This reduction was seen in both inpatient discharges (8.2% lower claim volume than 2019) and emergency department visits (27.3% lower claim volume than 2019). This was likely the result of hospital care being redirected to address the care for COVID-19 patients while elective surgeries and other outpatient care services were being postponed. '''ICD Coding between 2015 and 2016: ''' The nationwide switch from ICD-9-CM to ICD-10-CM hospital diagnosis coding on October 1, 2015 disrupted trends for some diseases and conditions. Interpret trend data in this report with caution. Also note that New Jersey's data for October through December, 2015 was recoded to ICD-9-CM so that entire year of data was coded the same way.Related Health Objectives and Indicators
