Among 29 038 patients (97.4%) who survived their index injury, 3899 (13.4%) experienced reinjury. The 7-year probability of any reinjury was highest among individuals with index stabbing (19.5% [95% CI, 17.5%-21.8%]) and blunt assault (17.4% [95% CI, 16.6%-18.2%]) injuries. Patients with index blunt assault injuries were more likely to experience blunt assault reinjury (7-year probability: 13.2% [95% CI, 12.6%-13.8%]) compared with other reinjury types.
