Sepsis screening tools for predicting infection triggers and outcomes in diabetic ketoacidosis

Background: An early prediction of infection is challenging in diabetic ketoacidosis (DKA). Methods: This prospective cohort study aimed to assess effectiveness of various sepsis screening tools in predicting infections and prognosis in DKA. Results: Among 141 cases, infection (44.0%) was the commonest precipitating factor. A Sequential Organ Failure Assessment score ≥4 showed high specificity (82.28%) and high positive likelihood ratio (2.64) but limited sensitivity (46.77%). Conversely, Systemic Inflammatory Response Syndrome ≥2 exhibited good sensitivity (95.16%) but a high false-positive rate (84.28%). National Early Warning Score ≥7 and Quick Sequential Organ Failure Assessment ≥2 had low sensitivity and specificity. These sepsis tools also demonstrated low prognostic accuracy for mortality. Conclusion: Sepsis screening tools have limited predictive accuracy for infections and mortality in DKA.
