Introduction:

the use of prognostic mortality scores is a very useful tool in intensive care units, allowing a better approach to medical care.

Objective:

to determine the usefulness of APACHE II in the Emergency Intensive Care Units at Celia Sanchez Manduley General Hospital.

Methods:

an observational, analytical and cross-sectional study was carried out in the period from April to June 2018 with 68 patients. To identify the statistically significant differences between the categories of some of the variables studied, the Chi-square statistic was used, with p <0.05 being considered significant. To calculate the discrimination, the area under the curve with 95 % confidence intervals was analyzed, and the calibration was also examined through the standardized mortality ratio.

Results:

cerebrovascular diseases prevailed (27,9 %), 35 patients (51,4 %) reached the APACHE II ≥15 scores, intermediate care unit was the destination service that admitted the most patients (39,7 %). Eighteen (18) patients died, of them 14 were admitted having APACHE II ≥15 scores (77,7 %, p=0.009). The mortality rate observed was 18, the standardized ratio of mortality reached 1,04, and the area under the curve was 0,679 p=0,025 (IC: 0,538-0,820).

Conclusions:

APACHE II can be a useful tool in intensive care units, allowing a better approach to medical care.
