An injury serious enough that a medical professional was consulted. For the motor vehicle, home and public venues, the National Safety Council uses the medically consulted injury estimates from the National Health Interview Survey. The Council uses the total recordable case estimate, using OSHA’s definition, published by the Bureau of Labor Statistics (BLS) to estimate the number of workplace injuries. Because the BLS estimate excludes self-employed, unpaid family workers and federal government employees, the Council extrapolates the BLS estimate to reflect the total worker population.
