Unintentional Injuries

Unintentional injury can be defined as “any injury that is not caused on purpose or with intention to harm”[1]. It is a broad category that includes injuries from causes such as motor vehicle collisions, falls, poisoning, drowning, suffocations and work-related or sports-related injuries1. Different types of unintentional injury may have unique patterns in different subpopulations such as younger groups experiencing greater motor vehicle collisions or older adults experiencing greater falls1.

                                   

Hospitalizations

From 2010 to 2014, hospitalization rates from unintentional injury were statistically higher in the NWHU compared to the province as a whole. The NWHU had 571.1 hospitalizations per 100,000 per year while Ontario had 383.0 per 100,000 per year.

Males in the NWHU area had higher rates of hospitalization than females (619.6 per 100,000 per year vs 517.0 per 100,000 per year), with the difference being statistically significant. As well, hospitalizations for unintentional injury increased with age; where those 0-19 years of age had the lowest average rate of 308.8 cases per 100,000 while those ages 75 years and older had the highest average rate of 3,096.6 cases per 100,000.
