Calculate APACHE II Score
Understanding the APACHE II Score
The Acute Physiology and Chronic Health Evaluation (APACHE II) score is a severity-of-disease classification system designed to measure the severity of disease for adult patients admitted to intensive care units (ICUs).
Score Interpretation
APACHE II scores range from 0 to 71, with higher scores corresponding to more severe disease and higher risk of death.
Critical Values
Scores above 35 are associated with >80% mortality rate in most patient groups.
Clinical Applications of APACHE II Score
ICU Triage
Helps determine appropriate level of care and resource allocation
Outcome Prediction
Estimates mortality risk and guides treatment decisions
Quality Assessment
Benchmarking ICU performance and care quality
Latest Research on APACHE II Score
Predictive Accuracy
Recent studies confirm APACHE II's strong predictive value for ICU mortality across diverse patient populations.
Modern Applications
Integration with electronic health records has improved scoring accuracy and clinical workflow efficiency.
Comparative Analysis
APACHE II maintains its relevance despite newer scoring systems, particularly in resource-limited settings.
Components of APACHE II Score
Physiological Assessment
Evaluates 12 physiological measurements including vital signs and laboratory values
Age Evaluation
Incorporates age-related risk factors into the scoring system
Chronic Health Status
Accounts for severe organ system insufficiency or immunocompromised state
Best Practices for APACHE II Scoring
Timing
Calculate within first 24 hours of ICU admission using worst values
Data Accuracy
Ensure precise measurement and recording of all physiological variables
Regular Monitoring
Track score changes to assess treatment response and disease progression
The APACHE II Score calculator is designed for healthcare professionals. Results should be interpreted alongside clinical judgment and other relevant patient data.
