Health Indicator Report of COPD Hospitalizations and ED Visits
Chronic Obstructive Pulmonary Disease (COPD) is a large group of lung diseases characterized by airflow obstruction and is often associated with symptoms related to difficulty in breathing, but can be present without any symptoms. The most important and frequent conditions in COPD are chronic bronchitis and emphysema, but also includes other diagnoses. Chronic lower respiratory disease, primarily COPD, was the third leading cause of death in the United States in 2014 (1). Almost 15.7 million Americans (6.4%) reported that they have been diagnosed with COPD (2). However, it is commonly accepted that COPD is frequently underdiagnosed (3), so the actual number may be higher. [[br]] [[br]] ---- # National Center for Health Statistics.

Data Interpretation IssuesAs of October 1, 2015, the U.S. is currently using the 10th revision of the International Classification of Diseases (ICD-10) to code hospitalizations and emergency department visits. Prior to the change, COPD hospitalizations and emergency department vists were defined as any ICD-9 primary diganosis code that included 490, 491, 492, and 496. Code 493.2 was used if any of the previous code were present in secondary diagnosis codes. These are now defined using ICD-10 codes J40, J41, J42, J43, and J44. Comparison of data prior to the code change may not be appropriate. A measure using all COPD hospitalizations will include some transfers between hospitals for the same person for the same event. Variations in the percentage of transfers or readmissions for the same event may vary by geographic area and could impact rates. Data on race and ethnicity are not routinely collected in all states. This data is not consistently recorded on medical records and when available is complicated further by non-standard definitions of race and ethnicity, the use of combined race/ethnicity, reporting of multiple race categories, and differences in self-report versus registrar reporting. Without reciprocal reporting agreements with abutting states, statewide measures and measures for geographic areas (e.g., counties) bordering other states may be underestimated because of health care utilization patterns. Each state must individually obtain permission to access and, in some states, provide payment to obtain the data. Veterans Affairs, Indian Health Services, and institutionalized (prison) populations are excluded. Practice patterns and payment mechanisms may affect diagnostic coding and decisions by health care providers to hospitalize patients. Sometimes the mailing address of a patient is listed as the residence address of the patient. Patients may be exposed to environmental triggers in multiple locations, but geographic information is limited to residence.
