Evaluation of stabbing assault injuries in a tertiary emergency department: a retrospective observational study.

ABSTRACT

BACKGROUND: Approximately 458,000 victims were deceased from intentional violence in 2021. A stabbing assault causes 25% of homicides. The study aims to evaluate injury patterns, trauma scores, radiological findings, types of treatment, and outcomes of stab assault patients admitted to a tertiary emergency department (ED). METHODS: This is a retrospective observational study of stabbing injury patients in the ED of Hacettepe University, Turkey. The sites and patterns of injury, radiological findings, treatment methods, consultations, and complications are acquired from the patient's files. Trauma scores and frequency of outcomes, such as the need for surgery, hospitalization, or mortality, were calculated for all patients. RESULTS: Among the 648 patients, 564 (87%) were male. The median age was 28 (interquartile range [IQR]13). The commonly injured body parts were the extremities (75%), thorax (21.9%), and abdomen (16.9%). The median RTS was 7,84 (IQR0), and the median ISS was 2 (IQR3). The fluid was detected in 13 of 88 patients by FAST, solid organ injuries in 21 patients, and gastric and intestinal injuries in 11 patients by abdominal CT. One hundred sixty-one patients underwent moderate and major surgery. Complications developed in 13 patients. 74,4% of the patients (n = 482) were treated in ED and 21.8% (n = 141) of patients were hospitalized in wards, 2.3% (n = 15) in intensive care unit and 1.5% (n = 10) patients died. GCS, RTS, and probability of survival (Ps) were significantly lower, and ISS was significantly higher in deceased patients and patients who needed erythrocyte replacement. CONCLUSION: The majority of stab wounds were detected in extremities, but severe and lethal stabbing injuries were on the thorax and abdomen. In thoracoabdominal stabbing injuries, x-rays and FAST can be ineffective in detecting critical and fatal injuries. Therefore, thoracic and abdominal CT should be planned early to detect possible causes of death and make a timely and accurate diagnosis. Lower GCS, RTS, and Ps or higher ISS scores were related to the need for erythrocyte replacement.
