Body: Despite the increase of geriatric population, studies for geriatric critical care are still scarce. A
retrospective study was performed to evaluate outcomes and prognostic factors of medically-ill geriatric
patients receiving mechanical ventilation (MV). Methods: Medical records of patients ≥70 year-old receiving
MV in intensive care unit (ICU) except cardiologic ICU from 2008 to 2010 were reviewed. Treatment
outcomes were compared between group A (age: 70-79) and B (age ≥80). Prognostic factors were
evaluated between survivor and non-survivor. Results: A total of 186 (n=115 in group A vs. n=71 in group B)
patients were analyzed. The mean APACHE II and SOFA scores at ICU admission were not different
between the groups (31.9 ± 7.0 vs. 31.3 ± 7.1 for APACHE II, P=0.822, and 10.9 ± 3.5 vs. 10.6 ± 3.2 for
SOFA, P=0.599). The median days (range) of MV were 9 (3-184) in group A and 9 (2-80) in B (P=0.235).
Hospital mortality were 57.4% in group A and 54.9% in B (P=0.742). The age was not significant predictor of
mortality in univariate analysis [the odds ratio (OR) 0.99, 95% confidence interval (CI); 0.948-1.036,
P=0.689]. In multivariate analysis based on parameters of APACHE II score, malignancy (the OR 7.119,
95% CI; 1.529-33.135, P=0.012) and APACHE II score were statistically significant (the OR 1.089, 95% CI;
1.041-1.139, P<0.001). Analyses based on SOFA score also showed that malignancy (the OR 8.230, 95%
CI; 1.813-37.365, p<0.006) and SOFA score (the OR 1.181, 95% CI; 1.072-1.301p=0.001) were significant.
Conclusions: The hospital mortality was not affected by age in geriatric patients. The presence of
malignancy and severity of illness were significant prognostic factors.
