Almost two million individuals work in Louisiana. Every year, thousands of these workers are injured on the job or become ill as a result of exposure to health and safety hazards at work. These work-related health conditions have high human and economic costs not only for workers and employers but also for society at large.1 Workers' compensation claims alone in Louisiana cost approximately $580 million in 2007.2 Work-related injuries and illnesses can be prevented. Successful approaches to making the workplace safer begin with having the data necessary to understand the problems. The Louisiana Office of Public Health/Section of Environmental Epidemiology and Toxicology's Occupational Health & Injury Surveillance Program (OPH/SEET) conducts surveillance of injuries, illnesses, deaths, and hazards among Louisiana workers. This project began in 2006 through funding from the Center for Disease Control and Prevention/National Institute of Occupational Safety and Health (CDC/NIOSH). To help state health departments with their surveillance activities, a set of occupational health indicators was developed by a State-Federal Workgroup composed of representatives from state occupational health programs, the Council of State and Territorial Epidemiologists (CSTE), and CDC/NIOSH. An occupational health indicator is a specific measure of a work-related disease or injury, or a factor associated with occupational health, such as workplace exposures, hazards, or interventions, in a specified population. Indicators allow a state to compare its health or risk status to that of other states, to evaluate trends over time within the state, and to guide priorities for prevention and intervention efforts. These indicators are collected and compiled annually. This document briefly summarizes some of Louisiana's occupational indicator data. When available, national data are presented for comparison purposes. The reporting period may vary by indicator due to differences in the number of years of data available from the various data sources. Because no single data source adequately characterizes the occupational health issues for Louisiana, multiple data sources were used. Technical notes and a description of the data sources are included at the end of the document.
