A Glimpse into the Prognostic Factors of Outcomes for Isolated, Operated Severe Traumatic Head Injury Patients in a Resource Constrained Trauma Center Setup

Abstract

Background Severe traumatic brain injury (STBI) continues to burden health care in developing countries. This study focuses on STBI patients undergoing surgical intervention to understand the factors affecting their outcomes in a constrained trauma center setup. Aim This aims to study the epidemiological and clinical factors to understand the long-term morbidity, mortality risks, and triaging among STBI patients requiring surgery. Methods A prospective observational study was conducted on 227 isolated STBI patients with Glasgow Coma Scale (GCS) ≤ 8 who underwent surgical evacuation of intracranial lesions. Patients were classified based on their neurological status and lesions on computed tomography head. Postoperative data on complications were collected. At 6-month follow-up, patients with Glasgow (Extended) scores of 7 to 8 were deemed good outcomes, and scores of 1 to 6 were deemed poor. Cox regression analysis was used to identify independent influencing factors, with p < 0.05 as statistically significant. Results The clinicoradiological factors including age (p = 0.02), asymmetric pupillary reaction (p = 0.002), low presenting pulse rate (p = 0.041), and low systolic and diastolic blood pressure (p = 0.016 and p < 0.0001, respectively), low GCS (p = 0.011), midline shift > 5 mm (p < 0.0001), and obliterated basal cisterns were significantly associated with poor outcome. Tracheostomy, respiratory tract infection, bedsore, meningitis, deep vein thrombosis, cerebrospinal fluid leak, and bone flap site infection were significantly associated with survival of the patients (p = 0.036). The most common cause of mortality during home care included respiratory tract infection and was associated with the care of the tracheostomized. GCS (p < 0.0001), age (p = 0.005), and alcohol use (p = 0.034) were independent predictors for the outcome of patients. Conclusion This study helps clinicians predict prognosis, postoperative recovery, manage challenges, counsel caregivers, and predict long-term patient outcomes.
