Assessing the Lactate-to-Albumin Ratio as a Predictor of 30-Day Mortality in Patients with Sepsis: A Retrospective Cohort Analysis

Category	Detail
Condition	Sepsis
Key Mechanisms	Systemic inflammation leading to organ dysfunction; lactate as a marker of tissue hypoperfusion; albumin as an indicator of physiological reserve and inflammation
Target Population	Adult patients diagnosed with sepsis admitted to emergency department
Care Setting	Emergency department of Dongyang People’s Hospital

Sepsis remains a leading cause of morbidity and mortality worldwide with high 30-day mortality rates.
Lactate-to-Albumin Ratio (LAR) is a composite biomarker combining lactate and albumin levels to improve prognostic accuracy in sepsis.
This study is the first to evaluate LAR as a predictor of 30-day mortality in a Chinese adult sepsis cohort.

Use Sepsis-3 criteria for defining sepsis as life-threatening organ dysfunction due to dysregulated host response to infection.
Measure lactate and albumin levels within 24 hours of admission for early risk stratification.

Prioritize early targeted interventions for patients with elevated LAR to improve outcomes.
Implement timely antibiotic administration, aggressive fluid resuscitation, and vasopressor support guided by risk stratification.

Monitor lactate and albumin levels on admission to assess prognosis.
Use LAR alongside other clinical parameters such as MAP, GCS, and hematological indices for comprehensive patient evaluation.

Consider confounding factors affecting lactate (e.g., liver dysfunction, medications) and albumin (e.g., nutritional status, chronic inflammation) when interpreting results.
Recognize that sole reliance on lactate or albumin may reduce prognostic accuracy.

1,205 adult sepsis patients admitted to emergency department between 2013 and 2021

Early measurement of LAR can identify high-risk patients who may benefit from prioritized and aggressive sepsis management strategies.

Obtain lactate and albumin measurements within 24 hours of hospital admission for sepsis patients.
Use LAR as a simple, composite prognostic marker to improve early risk stratification.
Incorporate LAR assessment into clinical decision-making to guide timely interventions and resource allocation.
Account for potential confounders affecting lactate and albumin levels to avoid misinterpretation.
Utilize logistic regression and ROC analysis to validate prognostic markers in clinical cohorts.
