Abstract
Background: Postoperative AKI in critically ill patients carries significant morbidity and
mortality yet it is understudied in Sub-Saharan countries. This study aims to assess the
prevalence, associated factors and outcomes of AKI in postoperative patients requiring ICU care.
Methods: Single center study of 152 patients in a 1 year retrospective analytic study in patients ≥
14years old with no underlying CKD. It is conducted in ICU of the largest teaching specialized
hospital in Ethiopia which has 6 beds dedicated to non-cardiac surgical patients.
Results: Overall prevalence of AKI was 23.7% (36) be KDIGO criteria of which 17(47.2%)
were stage 1, 11(30.6%) were stage 2 and 8(22.2%). Independent predictors of AKI were
surgeries outside gastrointestinal and cardiothoracic surgery (0.024(0.03-0.385)0.08), emergency
surgery (OR: 11.5(1.343-98.69)), Estimated blood loss >1500ml (OR: 10.418(2.01678.183)0.023),
Conclusion: AKI is highly prevalent among patients admitted to ICU postoperatively. It is
associated with increased length of ICU stay. Its predictors are cardiothoracic and
gastrointestinal surgery, higher estimated blood loss and emergency surgery.
