Abstract

PURPOSE:  Chronic Obstructive Pulmonary Disease (COPD) is a major health concern. The majority of COPD is caused by cigarette smoking. However, occupational exposures can also lead to the development of COPD in approximately 30% of patients. One industry where occupational exposures frequently lead to lung disease is agriculture. The Omaha Veteran’s Administration Hospital (OVAH) serves a largely rural area and many patients have worked in agriculture. However, there are no good estimates of the number of COPD patients with a history of agricultural exposure in our area.

METHODS:  We identified a cohort of patients with COPD by reviewing all pulmonary function tests done at the OVAH between November 2004 and March 2005. Obstructive lung disease was defined as a FEV1/FVC ratio of ≤ 70% and FEV1 ≤ 80% as per GOLD Criteria. A random sample of this cohort was administered a telephone survey based on NHANES III questionnaire. It detailed demographic data, smoking history, pulmonary symptoms and history of agricultural exposures.

RESULTS:  Participants included 150 veterans with a mean age of 68.2 (standard deviation=10.8). A history of agricultural exposure was elicited in 68% (95% confidence interval: 61%-75%) of subjects. Of those that had worked in agriculture, the types of exposures varied, with 21% working in hog confinement barns, 30% on dairy farms, 12% on poultry farms.

CONCLUSION:  In health systems that serve rural areas, patients with COPD commonly have a history of agricultural exposures. Exposures such as these can contribute to the development of COPD.

CLINICAL IMPLICATIONS:  Health care workers in rural areas should include agricultural exposures as an important part of the social/occupational history in COPD patients.
