This prospective diagnostic accuracy study evaluates the performance of presepsin and C-reactive protein (CRP) as early biomarkers for suspected sepsis in adult burn patients. From January 2021 to December 2022, 370 patients with ≥20% total body surface area burns admitted to the Burn Intensive Care Unit at Hallym University Hangang Sacred Heart Hospital were screened; 221 met inclusion criteria. At each clinical suspicion of sepsis (≥2 SIRS criteria), venous blood was drawn for simultaneous measurement of presepsin (via chemiluminescent immunoassay) and CRP (via immunoturbidimetric assay). Diagnostic accuracy will be quantified by sensitivity, specificity, positive/negative predictive values, and area under the ROC curve. The goal is to determine whether presepsin outperforms CRP for early sepsis detection in severe burn patients.

Diagnostic accuracy of presepsin for early sepsis detection
Timeframe: At the time of clinical suspicion of sepsis (Day 0), and daily for the following 7 days (Day 1 through Day 7).
