title: [Efficiency of APACHE II and III scoring system in the prognostication of patients older than 75 years].
abstract: 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.
