ECWHSP data can now be accessed using the Coal Workers' Health Surveillance Program (CWHSP) Data Query System

Enhanced Coal Workers' Health Surveillance Program (ECWHSP)

The prevalence of coal workers' pneumoconiosis (CWP), sometimes referred to as "Black Lung Disease," among long-term underground miners that participated in chest x-ray screening decreased from the 1970s to the 1990s. However since 1999, the prevalence of CWP among U.S. coal miners is increasing in mines of all sizes, and the more serious advanced disease of Progressive Massive Fibrosis (PMF) is much more prevalent among miners from underground mines with fewer than 50 workers. To more adequately investigate the trends of CWP throughout the United States, NIOSH, in collaboration with MSHA, has developed, staffed, and implemented the ECWHSP. Surveys are being completed that include work histories, spirometry testing, and radiographic examinations that are gathered in a specially designed mobile examination unit by trained personnel. Reports of individual health findings are sent to each participant.

NIOSH developed the video, "Faces of Black Lung", to be used as a tool to increase participation in the ECWHSP, as well as in the original

CWHSP , and other activities directed at preventing the health effects of Black Lung. The goal of the video is to inform the public about the devastating health effects of the disease. A "personal face" has been put on the disease through this video, which consists of unscripted personal interviews with miners that had advanced black lung disease, along with information about the NIOSH Programs. Members of the medical staff that treat miners, currently employed coal miners, coal operators, and medical personnel, as well as others interested in the health of coal miners, will learn more about this disease and will hopefully be motivated to participate in activities aimed at preventing it.

A Data Query System for the The Coal Workers' Health Surveillance Program (CWHSP) has been developed to produce tables and maps using an interactive system. The query system generates tables by Disease Severity Level and Disease Severity Prevalence by demographic and geographical criteria for the total number of underground miners that participated in the CWHSP programs.
