Abstract
Background: The number of elderly patients referred to the ICU is rising quickly along
with the aging population globally. Due to previous medical conditions and age-
associated alterations in their bodies, these individuals have a higher chance of mortality.
Geriatric mortality was high even in developed countries and sub-Saharan African
countries had the highest rates of mortality including our country Ethiopia. Different
factors affected these vulnerable populations.
Objective: To assess mortality and associated factors of geriatric patients admitted to the
intensive care unit of Addis Ababa Public Hospitals.
Method: A multicenter retrospective cohort study was conducted among geriatric
patients in Addis Ababa public hospitals who were admitted to the adult ICU. A total of
302 geriatrics who fulfilled the criteria were included in this study. Data were collected
by pretested structured questionnaire from the patient card and ICU log book. After that
collected data were entered into the SPSS 26 version for analysis. The association
between the risk factors and dependent variable was assessed by using logistic regression.
Bivariate and multivariable logistic regressions were employed. A variable with a p-value
< 0.05 in multivariable was considered statically significant.
Result: There was a 42.1% incidence of geriatric death in our critical care units. Aging
(AOR=9.436, 95%CI, 2.300 – 38.716), MV (AOR=7.281, CI, 2.364 – 22.429),
vasopressors (AOR=10.982, CI, 3.658 –32.976), decrease in level of consciousness
(AOR=4.766, CI, 1.606 – 14.145), duration of MV (AOR=6.909, CI, 2.138 – 22.322),
and length of ICU stay (AOR=15.599,CI, 4.925 –51.970) were the determinants of
mortality in this population age.
Conclusion: This study indicated that there was high number of mortality rate and
determinant factors that influence mortality were aging, MV, vasopressors, decrease in
level of consciousness, duration of MV and length of ICU stay.
