Progressive Massive Fibrosis in Coal Miners From 3 Clinics in Virginia

Since 1970, the Coal Workers' Health Surveillance Program (CWHSP), administered by the National Institute for Occupational Safety and Health, has offered periodic chest radiographs to working US coal miners.1 The primary purpose of the CWHSP is early detection of coal workers' pneumoconiosis to prevent progression to disabling lung disease, including progressive massive fibrosis (PMF). By the late 1990s, PMF was rarely identified among miners participating in the CWHSP. However, a 2014 report documented an increase in the prevalence of PMF in Appalachia.2 On February 1, 2017, the director of a network of 3 federally funded black lung clinics (which primarily serve former miners, and are not affiliated with the CWHSP) in Southwest Virginia requested assistance to determine the burden of PMF in patients served by the clinics.
