Introduction: Sepsis is a leading cause of death in the Intensive Care Unit (ICU) in developed countries and its incidence is increasing. Many scoring systems are used to assess the severity of disease in patients admitted to the ICU. SOFA score to assess the degree of organ dysfunction in septic patients. The Acute Physiology and Chronic Health Evaluation II (APACHE II) scoring system is most often used for patients admitted to the ICU. CCI scoring system to assess the effect of comorbid disease in critically ill patients on mortality. The study aimed to describe the characteristics of the use of scoring to predict patients’ mortality admitted to Haji Adam Malik Hospital. Methods: This is an observational study with a cross-sectional design. A total of 299 study subjects met the inclusion criteria and exclusion criteria, three types of scoring, namely SOFA score, APACHE II score, and CCI score were used to assess the prognosis of septic patients. Data analysis was performed using SPSS. P-value <0.05 was considered statistically significant. Results: A total of 252 people (84.3%) of sepsis patients died. The mean age of the septic patients who died was 54.25 years. The SOFA score ranged from 0-24, the median SOFA score in deceased sepsis patients was 5.0. The APACHE II score ranged from 0-71, the median APACHE II score in deceased sepsis patients was 23.0. The CCI score ranged from 0-37, the median CCI score in deceased sepsis patients was 5.0. Conclusion: Higher scores are associated with an increased probability of death in septic patients. Keywords: Sepsis; mortality predictor; SOFA score; APACHE II score, CCI score.
