The Work-Related Injury Statistics Query System

The Work-Related Injury Statistics Query System (Work-RISQS) is an interactive query tool to obtain estimates for the number of nonfatal occupational injuries treated in U.S. hospital emergency departments (EDs). The data were derived from the National Electronic Injury Surveillance System—Occupational Supplement (NEISS-Work). Through a national probability-based sample of U.S. hospital EDs, NEISS-Work collected data on civilian workers who were injured on the job. Work-RISQS users may interactively query on worker demographic characteristics, nature of injury, and incident circumstances for ED-treated injuries from 1998 through 2023 to obtain national estimates.

NIOSH stopped collecting data after 2023. This site will continue to be maintained but additional years of data will not be added.

• Medical: Nonfatal injuries treated in an emergency department
• Population: Civilian non-institutionalized workers
• Work: Doing work for pay or other compensation; doing agricultural production; and working as a volunteer for an organized group
• Demographics: All workers (self-employed, private industry, and government)

Work-RISQS users can calculate rates of ED-treated injuries using injury estimates obtained through Work-RISQS and worker estimates obtained through the Employed Labor Force (ELF) query system.

DISCLAIMER: The NEISS-Work data were collected by the NIOSH Division of Safety Research in partnership with the U.S. Consumer Product Safety Commission (CPSC), the operator of the basic NEISS program.
