Abstract

BACKGROUND: Injury is the leading cause of preventable morbidity and mortality in Canada. The "ice berg" effect in injuries was proposed to address the injury statistics that are often poorly documented. The aim of this investigation was to quantify the severity and magnitude of iceberg effect in Ontario, Canada. METHODS: Data from Vital Statistics (1999, mortality), Canadian Institute for Health Information (2001, hospitalizations), Census (2001, demographic information), National Ambulatory Care Reporting System (2001, emergency department visits), and the Canadian Community Health Survey (2000/01, other injuries) were used to construct the Ontario injury iceberg for ages 12 years and older. RESULTS: There were 79,577 fatalities in Ontario in 1999; 2,645 were attributable to injuries (crude rate: 2.3 per 10,000). Of the 913,540 hospitalizations (2001), 67,301 were caused by injuries. There were 3,520,253 emergency department (ED) visits (2001) and 959,278 were attributable to injuries. For injuries treated elsewhere, the most common treatment site was the physician's office (23.3%). The most common cause of injuries (CCHS) was falls (37.4%) and exertion/movement (20.5%). There were 1,928,000 injuries causing functional impairment (one injury to five individuals in the population). INTERPRETATION The high ratio of injury-related ED visits to deaths illustrated the high volume of injuries that present to the ED. The ratio of injuries resulting in functional impairment to the population demonstrates.that such injuries can be problematic, even if not resulting in hospitalization. Constructing the injury iceberg using valid data should assist researchers and decision-makers in priority setting.
