Key result
The POSSUM score was superior to APACHE II for predicting 30-day mortality in patients admitted to a surgical high-dependency unit (AUC 0.75 vs 0.54; P<0.002).
Why the study?
Does the POSSUM score predict 30-day morbidity and mortality better than the APACHE II score in patients admitted to a surgical high-dependency unit?
Population
117 consecutive admissions to a high-dependency unit after major surgery
Comparison
POSSUM score vs APACHE II score
Design
Cohort
Follow-up
30-day

Supports POSSUM for mortality prediction in surgical HDU patients; observational data leave open whether it should alter practice or guidelines.

Effect estimate: AUC 0.75
p-value: p=<0.002
POSSUM is superior to APACHE II for predicting 30-day mortality and morbidity in patients admitted to a high-dependency unit after major surgery.
Jones et al. (1992) conducted an observational in Admissions to a high-dependency unit after major surgery (n=117). POSSUM score vs. APACHE II score was evaluated on 30-day mortality (AUC 0.75, p=<0.002). The POSSUM score was superior to APACHE II for predicting 30-day mortality in patients admitted to a surgical high-dependency unit (AUC 0.75 vs 0.54; P<0.002).
