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 are 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 collects 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 the present to obtain national estimates.

Work-RISQS Case Definition
  • 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)

Important Note

The case criteria changed in 2015 and caution should be used in comparing these data to data from previous years. See the Technical Info section for more details on the case criteria change.

Work-RISQS Rates

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.

How to Calculate Rates
