Summary
A new computer program accurately calculates the Sequential Organ Failure Assessment (SOFA) score automatically. This validated tool streamlines intensive care unit (ICU) decision-making by eliminating manual data collection.
Area of Science:
- Critical Care Medicine
- Health Informatics
- Medical Technology
Background:
- The Sequential Organ Failure Assessment (SOFA) score is crucial for assessing patient severity in intensive care units (ICUs).
- Manual calculation of SOFA scores is time-consuming and prone to errors.
- Automating SOFA score calculation can improve efficiency and accuracy in ICUs.
Purpose of the Study:
- To validate a computer program for automatic Sequential Organ Failure Assessment (SOFA) score calculation.
- To compare the accuracy of automated SOFA scoring against manual chart review (the gold standard).
- To assess the feasibility of implementing an automated SOFA scoring tool in a real-time electronic medical record (EMR) system.
Main Methods:
- Retrospective cross-sectional analysis using a derivation cohort to compare automatic vs. manual SOFA scores.
- Independent validation cohort analysis to confirm accuracy.
- Prospective observational analysis of the computer program integrated into the AWARE Dashboard EMR system.
Main Results:
- Good agreement observed between manual and automatic SOFA score calculations in both derivation (0.02 ± 2.33) and validation (0.29 ± 1.75) cohorts.
- The automated tool demonstrated validated accuracy when implemented in the AWARE EMR system (N=60).
- The computer program accurately calculates SOFA scores, facilitating ICU decisions.
Conclusions:
- An EMR-based automatic tool accurately calculates SOFA scores.
- This automated tool can significantly facilitate ICU decision-making by eliminating manual data collection.
- The validated computer program is suitable for real-time use in electronic medical record systems within the ICU environment.
