Due to improvements in the health care system worldwide, human life expectancy has increased, resulting in a greater number of geriatric patients diagnosed with acute kidney injury (AKI). We evaluated the incidence and outcome of AKI in octogenarians, as studies in this age group are few.


Design: Retrospective chart review.
Setting: The medical ward of our tertiary-care hospital in northern Jordan.
Participants: All patients aged 80-89 admitted to our medical ward between January 2010 and December 2013. Patients with stage IV and V chronic kidney disease were excluded.
Measurements: The incidence of AKI determined by the Acute Kidney Injury Network classification, mortality, and hospital length of stay.


There were 850 patients admitted during the study period. Of these, 135 were excluded from our analysis. The most common admission diagnoses were uncontrolled diabetes mellitus and acute coronary syndrome. AKI occurred in 216 patients (30.2%). In these cases, Stage 1, Stage 2, and Stage 3 disease were present in 59%, 17.5%, and 23.5%, respectively. Of the 115 patients who died before discharge (16.1%), 87 (75.6%) had developed AKI. Hypertension, the use of angiotensin receptor blockers and non-steroidal anti-inflammatory drugs, heart failure, and exposure to radiologic contrast media were significant risk factors for AKI.


Appropriate management of diabetes and hypertension in octogenarians will likely decrease the incidence of AKI in this age group leading to reduced hospital length of stay and mortality.
