Aims: Identification of priorities in intensive care units is a matter of high complexity due to dysfunction in patients'
vital organs such as circulatory, lung and kidney which often undergo rapid changes in the mentioned wards. Nurses
should therefore be able to make decisions with respect to priorities to resolve this problem. In this regard, the present
study was undertaken to investigate the efficacy of APACHE II instrument.
Methods: In the present study in 2010, 70 patients of intensive care units with congestive heart failure and chronic
obstructive pulmonary disease were evaluated, for whom the APACHE II scores were calculated. The research was
conducted in a cross-sectional approach, in which patients' death or survival was recorded. SPSS15 statistical software
was applied for statistical analysis, and clinical parameters were investigated using descriptive-statistical tests.
Results: The study findings showed significant difference between survivors and non-survivors with respectively 13.6
(±3.5) and 17 (±2.5) as the mean (±SD) APACHE II scores. Fifteen percent mortality rate was observed in patients with
scores under 15, while it was 36% in those with scores ranging from 16 to 19, and almost 100% in participants
obtaining 20 to 30 scores.
Conclusion: The APACHE II scoring system has been successful in predicting the mortality rate in intensive care unit
patients and it has been found to be higher than the standard level in all patients.
