About 100 a year in the USA.
An estimated 195 100 individuals (95% confidence interval, 140 400-249 800) were treated in US EDs for snow shovel–related incidents during the 17-year study period, averaging 11 500 individuals annually (SD, 5300). The average annual rate of snow shovel–related injuries and medical emergencies was 4.15 per 100 000 population. Approximately two thirds (67.5%) of these incidents occurred among males. Children younger than 18 years comprised 15.3% of the cases, whereas older adults (55 years and older) accounted for 21.8%. The most common diagnosis was soft tissue injury (54.7%). Injuries to the lower back accounted for 34.3% of the cases. The most common mechanism of injury/nature of medical emergency was acute musculoskeletal exertion (53.9%) followed by slips and falls (20.0%) and being struck by a snow shovel (15.0%). Cardiac-related ED visits accounted for 6.7% of the cases, including all of the 1647 deaths in the study. Patients required hospitalization in 5.8% of the cases. Most snow shovel–related incidents (95.6%) occurred in and around the home.
