Occupational Respiratory Disease Surveillance

State-Based Surveillance

Work-Related Asthma (WRA)

Massachusetts, Michigan, and New Jersey have maintained WRA surveillance programs since 1988. California has maintained a WRA surveillance program since 1993, and Washington began surveillance for WRA and 2002. New York conducts surveillance for all occupational lung diseases, including WRA, through its long-standing Occupational Lung Disease Registry. Health care professional reports represent the primary ascertainment source in Massachusetts, Michigan, New Jersey, and California. California identifies cases by reviewing data from Doctor’s First Reports (DFR) of Occupational Injury or Illness, a longstanding statewide health care professional reporting system linked to reimbursement for medical services. The primary ascertainment source in New York is hospital discharge data. Washington identifies cases through their state Workers’ Compensation system; employers in Washington are required to obtain State Fund insurance unless they are able to self-insure. Several states use multiple data sources to identify cases including hospital discharge data, emergency room data, workers’ compensation data, as well as Poison Control data in Michigan. State surveillance staff collect demographic, work-history, and medical information for case confirmation, classification, and description through a combination of data sources, review of medical records, and when possible, a follow-up interview with reported cases.

Surveillance Guidelines for State Health Departments

Recommended guidelines for identifying and reporting actual or suspected cases of work-related asthma.

AOEC Exposure Codes
External link: http://www.aoec.org/tools.htm
An exposure coding scheme which includes agents classified as "known asthma inducers" and is maintained by the Association of Occupational and Environmental Clinics (AOEC). To facilitate consistency in agent coding across states, putative causes of WRA for each case are coded using this scheme.

Asmapro: A web server for Occupational Asthma
External link: http://www.remcomp.com/asmanet/asmapro/asmawork.htm
An occupational asthma diagnostic tool for providers dealing with asthma in the workplace. Over 70 different occupational asthma cases reside in an html-based relational database, and each case can be retrieved by case id, by the agent (over 400 different agents are listed), or by patient's job (more than 140 different jobs are registered).

Haz-Map®
External link: http://hazmap.nlm.nih.gov/
An occupational toxicology database (of chemicals, jobs, and diseases) designed to link jobs to hazardous job tasks which are linked to occupational diseases and their symptoms.

NIOSHTIC-2 is a searchable bibliographic database of occupational safety and health publications, documents, grant reports and journal articles supported in whole or in part by NIOSH.
