Emergency Department Visits due to Chronic Obstructive Pulmonary Disease (COPD) by County, New Jersey, 2023
Why Is This Important?
Chronic obstructive pulmonary disease (COPD) is a chronic inflammatory lung disease that causes obstructed airflow from the lungs. Symptoms include breathing difficulty, cough, mucus (sputum) production and wheezing. COPD is caused by long-term exposure to irritating gases or particulate matter, most often from cigarette smoke. People with COPD are at increased risk of developing heart disease, lung cancer and a variety of other conditions. Emphysema and chronic bronchitis are the two most common conditions that contribute to COPD. Chronic bronchitis is inflammation of the lining of the bronchial tubes, which carry air to and from the air sacs (alveoli) of the lungs. It's characterized by daily cough and mucus (sputum) production. Emphysema is a condition in which the alveoli at the end of the smallest air passages (bronchioles) of the lungs are destroyed as a result of damaging exposure to cigarette smoke and other irritating gases and particulate matter. Chronic lower respiratory disease, primarily COPD, was the fourth leading cause of death in the United States in 2019. Over eleven million Americans are believed to have been diagnosed with COPD.
Definition
Emergency department (ED) visits due to chronic obstructive pulmonary disease (COPD). Primary diagnosis of COPD, defined by ICD-9 490-492, 493.2 (only when 490-492 or 496 is present), 496 or ICD-10 codes J40-44.
Data Notes
- Data have been age-adjusted to the U.S. 2000 standard population.
- Incidence rates per 10,000 population are age-adjusted to the 2000 US standard population (18 age groups: <5, 5-9, ... , 80-84, 85+).

Data Issues
Hospital Discharge Data Collection System (NJDDCS), New Jersey Department of Health
'''Missing data in 2022:''' Three hospitals in Camden and Gloucester Counties submitted their fourth quarter data after the file closure deadline so their data are missing from the 2022 inpatient and emergency department datasets. '''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. '''Caveats specific to 2017 data:''' NJDOH changed its vendor for hospitalization data collection in 2017 resulting in data loss at some facilities during the transition period. Additionally, The old vendor experienced a global malware incident in June 2017 that possibly resulted in the loss of some data in the system queue at that time. '''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.
American Community Survey, U.S. Census Bureau
The U.S. Census Bureau did not release its standard 1-year estimates from the 2020 American Community Survey because of the impacts of the COVID-19 pandemic on data collection.
