Prediction of Mortality in Acute Thermal Burn Patients Using the Abbreviated Burn Severity Index Score: A Single-Center Experience.

Background Burn injuries are highly variable and dynamic. The outcome of patients is influenced by various factors and requires prompt therapeutic interventions, including fluid resuscitation, for a favorable result. Although having varying shortcomings, many scoring indexes are developed and validated in Western countries to predict mortality in a burn patient. The Abbreviated Burn Severity Index (ABSI) estimates survival expectancy in a burn patient via various negative prognostic factors. This study describes the pattern of burn injuries to validate the ABSI as an outcome predictor in burnt patients. Methodology From January to December 2018, 100 patients participated in this observational research conducted in the Department of Surgery at Mahatma Gandhi Hospital's Burn Ward, a part of Dr. Sampurnanand Medical College, Jodhpur. Risk factors for death from a burn were patients' age and gender, the depth of the burn, the inhalation burn, and the total burned body surface area (TBSA). The area under the receiver operating curve (AUROC) was used to determine how well it could predict burn deaths. Results This study included 100 patients (69 men and 31 women, with a ratio of 2.22:1). In total, 73 patients survived, and 27 died (a mortality rate of 27%). The fatality rate increased with increased burn surface area, reaching 100% in patients with >80% burns (p < 0.0001). Additionally, those with an ABSI of >11 expressed 100% mortality rate (p < 0.0001). Conclusions In this study, older age, high burned surface area, concomitant inhalational burns, full-thickness burns, and a higher ABSI were found to be significant predictors of mortality.
