Objectives: Acute kidney injury is associated with significant morbidity and mortality. This study was done to determine the effect of acute kidney injury on duration of hospital and intensive care unit stay, need for mechanical ventilation and in- hospital mortality. Methods: All adult patients admitted to Intensive Care Unit between October 2021 and January 2022 were included in this study. Exclusion criteria ìncluded maintenance haemodialysis for end stage renal disease and development of acute kidney injury prior to transfer to intensive care unit. Acute Kidney Injury was defined using KDIGO definition. Data on duration of hospital/ intensive care unit stay, need for mechanical ventilation and in- hospital mortality was recorded. These were compared between patients developing acute kidney injury and the rest. Results: There were 163 patients aged 53.67± 21.69 years, including 95 (58.28%) males. Median (and interquartile range) duration of stay in hospital and intensive care unit were 9 (4- 15) and 2 (1- 6) days respectively. During stay in hospital, 37 (22.69%) patients died. Mechanical ventilation was required in 26 (15.95%) patients. Acute kidney injury developed in 37 (22.70%) cases. Haemodialysis was required in 11 (6.75%) patients. Development of AKI was associated with a longer stay in ICU (median 5 vs 2 days; p=0.023). However, there was no effect on total hospital stay (median 11 vs 8 days; p=0.179), need for mechanical ventilation (14.81% vs 16.18%; p= 0.860) or mortality (14.81% vs 16.17%; p=0.347). Conclusions: Acute kidney injury is a significant problem associated with a longer stay in intensive care unit. However, it is not associated with higher risk of death.
