ICU sedation, delirium & recovery
Prospective Evaluation of a Dynamic Acuity Score for Regularly Assessing a Critically Ill Patient’s Risk of Mortality
Authors' conclusion
Using prospectively collected data, the ViSIG Score produced risk groups for mortality with good sensitivity and excellent specificity.

- Participants
- 1,810 admissions
- Comparison
- ViSIG Score risk groups: 38-58 and 59-100 vs 0-37
- Outcome
- ICU mortality

- Low risk vs Moderate risk: P < 0.001 — across the three risk groups; the High risk group is also included
Further findings

- Performance on the validation dataset remained high
LOS, estimated costs, readmission
- Similar increases across risk groups
