Summary of Previous WoRLD Surveillance Reports

WoRLD Surveillance Report (1991)
www.cdc.gov/niosh/docs/91-113/91-113.html

The 1991 report is the first in the series of WoRLD Surveillance Reports. Data presented in the report, most of which relates to the 1968-1987 time period, originated from the National Institute for Occupational Safety and Health (NIOSH), the National Center for Health Statistics (NCHS), the Bureau of Labor Statistics (BLS), the Mine Safety and Health Administration (MSHA), the Occupational Safety and Health Administration (OSHA), the Department of Labor (DOL), the Health Care Financing Administration (HCFA), and the Social Security Administration (SSA). The 1991 report is organized into two major sections, one of figures and the other of tables. Within each section, data are presented in the following sub-headings: asbestosis, coal workers' pneumoconiosis, silicosis, exposure to cotton dust, pneumonopathy due to inhalation of other dust (i.e., byssinosis), hypersensitivity pneumonitis, toxic agents, dust diseases of the lung, and compensation.

WoRLD Surveillance Report Supplement, 1992

The 1992 supplement presents updated data for many of the figures and tables presented in the 1991 report, including mortality data through 1988. In addition, the 1992 supplement includes data not previously presented: (1) sex, race, geographic distribution, usual industry, and usual occupation, supplementing mortality data presented in the 1991 report; (2) number of discharges with silicosis, asbestosis, or coal workers' pneumoconiosis from the National Hospital Discharge Survey; and (3) reports of occupational asthma and silicosis from the Sentinel Event Notification Systems for Occupational Risks (SENSOR) Program.

WoRLD Surveillance Report, 1994

Data presented in the 1994 report originate generally from programs and activities described in the 1991 and 1992 reports. The 1994 report is divided into 11 major sections, most containing both figures and data tables. Ten sections summarize mortality and morbidity data and other information, such as occupational exposures, for types of pneumoconiosis, malignant neoplasms of the pleura, hypersensitivity pneumonitis, occupational asthma, and other lung conditions. The final section provides data from the Association of Occupational and Environmental Clinics (AOEC) Disease Surveillance Database. The 1994 report contains major additions, including previously unreported data, such as those from the National Health Interview Survey (NHIS) and the AOEC, and additional statistical measures, such as proportionate mortality ratios, both crude and age-adjusted rates at national and state levels, and years of potential life lost to age 65 and to life expectancy.

WoRLD Surveillance Report, 1996
www.cdc.gov/niosh/docs/96-134/96-134.html

The 1996 report focuses entirely on pneumoconiosis mortality and related exposures, providing updated mortality data from 1968 through 1992. It has three sections: (1) a section that describes data highlights and data limitations; (2) a section that updates and expands national data provided in the 1994 report; and (3) a section that provides detailed profiles of relevant data for each state in the U.S. Surveillance data include counts, crude and age-adjusted rates, years of potential life lost, and proportionate mortality ratios by industry and occupation. The 1996 report presents detailed tables of pneumoconiosis mortality data for each state and for the District of Columbia, as well as for counties within each state. It also presents county-level maps showing the geographic distribution of mortality for each pneumoconiosis and showing results of federal occupational exposure inspection sampling for agents that cause pneumoconiosis.

WoRLD Surveillance Report, 1999
www.cdc.gov/niosh/2000-105/2000-105.html

The 1999 report is similar in content and organization to the 1994 WoRLD Surveillance Report. It is structured into three sections with 13 sub-sections which summarize mortality and morbidity data and other information, such as occupational exposures, for each type of pneumoconiosis and all pneumoconioses, malignant neoplasms of the pleura, hypersensitivity pneumonitis, occupational asthma, and other lung conditions. Major additions were sub-sections for pulmonary tuberculosis and chronic obstructive pulmonary disease. Mortality data published in the 1994 and 1996 World Surveillance Reports are updated through 1996. The 1994 report contains major additions, including previously unreported data, such as that from the National Health and Nutrition Examination Survey (NHANES). Reports of occupational asthma and silicosis from the Sentinel Event Notification Systems for Occupational Risks (SENSOR) Program are updated through 1995; updated summaries from the Association of Occupational and Environmental Clinics (AOEC) are provided for 1991-1996.
