Trends in hospitalization with chronic obstructive pulmonary disease-United States, 1990-2005.

Chronic obstructive pulmonary disease (COPD) is the fourth leading cause of death in the United States and a major cause of morbidity and disability. To update national estimates and examine trends for hospitalization with COPD between 1990 and 2005, we analyzed data from the National Hospital Discharge Survey (NHDS). The results indicated that an estimated 715,000 hospitalizations with COPD, or 23.6 per 10,000 population, occurred during 2005, an increase in the number and the rate of COPD hospitalizations since 1990 (370,000 hospitalizations; rate = 15.9 per 10,000 population). To reverse increases in the number of COPD hospitalizations and decrease the burden of COPD, public health programs should continue focused efforts to reduce total personal exposure to tobacco smoke, including passive smoke exposure; to occupational dusts and chemicals; and to other indoor and outdoor air pollutants linked to COPD.
