Objective:
To observe the efficiency of both the APACHE II/III scoring systems in predicting the prognosis of patients older than 75 years.
Methods:
We calculated both the APACHE II and III scores in patients older than 75 years who were admitted to the geriatric intensive care unit (GICU) of our hospital in a duration of 6 months. The scores and predicting death rates were compared with the actual death rates.
Results:
There was definite correlation between the APACHE II/III scores and the actual death rates. Sensitivity of the APACHE II/III systems are 66.7% and 41.7% respectively. Specificity of the APACHE II/III systems are 90.9% and 100% respectively.
Conclusions:
Both the APACHE II/III systems can do well in predicting the prognosis of ICU patients older than 75 years, but APACHE III tends to underestimate the hospital death rate of elderly patients.
