Abstract
Objective: To compare APACHE IV and APACHE mortality rate sensitivity and specificity were
II scoring methods for patients admitted in an ICU 94.73% and 93.74% respectively, SMR of 0.94
with ALI and ARDS. and diagnostic value was 93.62%. APACHE II
Methodology: This comparative study was predicted mortality sensitivity and specificity were
conducted in ICU Lady Reading Hospital, 100% and 87%, SMR of 0.79 and diagnostic value

2012. All cases of ALI/ARDS were included in the Conclusion: APACHE IV scoring system is
study. Observed mortality rates were compared equally sophisticated as the APACHE II system in
with predicted mortality rates for both the predicting mortality rate in ICU patients with
APACHE IV and APACHE II scoring systems, ALI/ARDS. APACHE IV score (score>90) gives
standardized mortality ratio (SMR) and sensitivity probably additional reliable prediction of high
and specificity were determined. The mortality possibility of death in patients with ALI/ARDS than
percentages were predicted via APACHE IV APACHE II (score>25). Supplementary
