Abstract
Using data from national surveillance programs to obtain information on coal workers pneumoconiosis (CWP), silicosis, and asbestosis morbidity and mortality was discussed. The Division of Respiratory Disease Studies, NIOSH, is currently developing systems for monitoring CWP, silicosis, asbestosis, and other work related occupational lung diseases in the US. CWP, silicosis, and asbestosis have been specially targeted by the Public Health Service Objectives for the Year 2000 Program as occupational diseases that can be prevented. Data on CWP, silicosis, and asbestosis morbidity and mortality extracted from records of the National Center for Health Statistics (NCHS), National Hospital Discharge Survey (NHDS), and Medicare Provider Analysis and Review (MEDPAR) files and annual reports of the Bureau of Labor Statistics (BLS) were reviewed. Data contained in the NCHS files lists both underlying and contributing causes of death. They indicated that the number of deaths with CWP have remained well about 2,000 deaths per year (yr) since 1970. The number of deaths with silicosis have gradually decreased since the 1970s, from more than 1,000 to 300 deaths/yr, but appeared to have stabilized in recent years. Deaths with asbestosis increased during the 1970s and 1980s, from fewer than 100 to more than 700 deaths/yr. It was noted that because the NCHS lists both underlying and contributing causes of death, more than 60% of the deaths with CWP, 70% of those with asbestosis, and 50% of those with silicosis that occurred from 1979 through 1988 would have been missed if only data on underlying causes had been used. Data from the NHDS, MEDPAR, and BLS systems show the same temporal trends in CWP, silicosis, and asbestosis morbidity as seen for CWP, silicosis, and asbestosis mortality. The authors conclude that data contained in the various surveillance systems can be used to identify important trends in occupational disease occurrence. The data indicate that the number of asbestosis deaths is increasing, but has not yet reached the level of CWP mortality. Reports on silicosis have shown a promising decrease for several years, but the occurrence of silicosis now seems to have stabilized.
