Abstract
BACKGROUND: Mortality rates associated with total pneumoconiosis, including coal worker's pneumoconiosis (CWP), have remained elevated. METHODS: 2003-2013 pneumoconiosis mortality data obtained from National Center for Health Statistics and 2011-2013 Kentucky death certificates were analyzed. RESULTS: Total pneumoconiosis mortality rates showed significant linear decreases in West Virginia, Pennsylvania, Kentucky, and the U.S. from 2003 to 2013; Pennsylvania and Kentucky had comparable rates in 2003 but while Pennsylvania rates significantly decreased ∼3.0 deaths/million annually, Kentucky rates decreased only 0.5/million annually. Kentucky and Pennsylvania CWP fatality rates were also comparable in 2003 but while Pennsylvania rates decreased 82% over the study period, Kentucky rates decreased only 26%. Kentucky pneumoconiosis deaths primarily occurred in white Appalachian males in-hospital. Diseases leading to pneumoconiosis death were largely respiratory and cardiovascular, with autopsies rarely performed. CONCLUSIONS: Coal worker environmental exposure protection should be enhanced and pneumoconiosis surveillance improvements, including enhanced management of comorbid conditions like COPD, should be considered.
