- W4293163073 abstract "Background Blasts incidents impose catastrophic aftermaths on populations regarding casualties, sustained injuries and devastated infrastructure. Lebanon witnessed one of the largest non-nuclear chemical explosions in modern history – the August 2020 Beirut Port Blast. This study assesses the mechanisms and characteristics of blast morbidity and mortality and examines severe injury predictors through the Injury Severity Score. Methods A retrospective, multi-center cross-sectional study. Data of trauma patients presenting to five major acute-care hospitals in metropolitan Beirut up to 4 days following the blast were collected in a two-stage process from patient hospital chart review and follow-up phone calls. Results 791 patients were included with a mean age of 42 years. The mean distance from the blast was 2.4 km (SD 1.9 km), 3.1% of victims were in the Beirut Port itself. The predominant mechanism of injury was being struck by an object (falling/projectile) (293, 37.0%) and the most frequent site of injury was the head/face (209, 26.4%). Injury severity was low for 548 (71.2%) patients, moderate for 62 (8.1%), and severe/critical for 27 (3.5%). Twenty-one deaths were recorded (2.7%). Significant serious injury predictors (ISS > 15) were sustaining multiple injuries (OR = 2.62, p = 0.005), a fracture (OR = 5.78, p < 0.001), primary blast injuries, specifically a blast lung (OR = 18.82, p = 0.001), concussion (OR = 7.17, p < 0.001), and eye injury (OR = 8.51, p < 0.001), and secondary blast injuries, particularly penetrating injuries (OR = 9.93, p < 0.001) and traumatic amputations (OR = 13.49, p = 0.01). 25.0% were admitted to the hospital, with 4.6% requiring the ICU. At discharge, 25 patients (3.4%) had recorded neurologic disability. Conclusions Most injuries sustained by the blast victims were minor. Serious injuries were mostly linked to blast overpressure and projectile fragments. Understanding blast injuries characteristics, their severity and management are vital to informing emergency services, disaster management strategies and hospital preparedness and consequently improving patient outcomes. Level of evidence and study type Prognostic and Epidemiologic, Level III" @default.
