Background: One of the most frequent causes of morbidity, disability and mortality in young adults is traumatic brain injury (TBI). Early recognition of TBI is critical for clinical decision-making and determining prognosis. The primary goal of the development of Rotterdam Computerized Tomography (RCT) scan grading system was to foresee prognostic outcomes pf TBI patient.

Objective: To find out the prognostic outcomes of TBI patients by using RCT scoring system.

Methods: A cross-sectional study was conducted from June 2022 to November 2022 at Ziauddin University Hospital Karachi. One hundred and sixty-two traumatic brain injury patients were consecutively selected from Emergency Department (ED). Each patient was clinically evaluated, vitals were measured and GCS scores were calculated at admission. Each TBI patient's RCT score was calculated to predict the prognostic outcome (mortality) and followed up to six months for the final outcome.

Results: Of the 162 TBI patients, male and female patients were 112 (69.1%) and 50 (30.9%) with a mean age of 41.4±18.4 years. Most of the TBI patients (96.3%) were presented with unintentional intent of injury and due to road traffic accidents (55.6%) and falls (37.7%). Mean GCS score was 12.4±3.5 and TBI severity was mild in most of the patients (72.8%) followed by moderate TBI (12.3%) and severe TBI (14.8%). Mean RCT score was 3.2±0.9 and six-month predicted mortality was 27.8%, while six-month mortality was 15.4%.

Conclusion: In the emergency department; the RCT grading system was found to be a reliable independent factor for predicting six-month mortality in patients presented with TBI.
