Pattern of acute kidney injury and its outcome in a tertiary care centre. International Journal of Research in Medical Sciences. 2020 Feb; 8(2): 618-6232320-60712320-6012http://imsear.searo.who.int/handle/123456789/211963Background: Acute kidney injury is a multiplex disease with severe morbidity and mortality. The trends of acute kidney injury vary according to the regions and the population under study. The aim of this study is to evaluate the trends of acute kidney injury and its outcome in a tertiary care hospital.Methods: The study was a prospective observational study conducted at a tertiary care hospital in a metropolitan city. A total of 102 patients of acute kidney injury were selected based on the Kidney Disease Improving Global Outcomes guidelines of acute kidney injury. The main trends of acute kidney injury presentation and its outcome were assessed.Results: Of 102 patients admitted, 42 had a sepsis related diagnosis (42.41%), 17 patients (17.16%) had cardiovascular disease related acute kidney injury and 12 patients (12.12%) had developed acute kidney injury due to drugs and poisons. According to RIFLE (risk of renal failure, injury to kidney, failure and loss of function and end-stage kidney disease) category, 43.96% of patients belonged to the risk category and 30.77% to the injury category. Of 34 patients in failure category, 23 recovered and 11 did not recover. Authors compared the trends of acute kidney injury in patients who recovered and who deteriorated. The mean serum creatinine values were 3.42 mg/dl in patients who didn’t recover from acute kidney injury and 2.05 mg/dl in patients who recovered. In patients of the recovered group, the mean urine output value is 783 ml/day; in deterioration group, 445 ml/day.Conclusions: Most common etiologies of acute kidney injury in this study include sepsis, drugs and poisons, cardiovascular diseases and diarrheal diseases in order of occurrence. High serum creatinine at admission and oliguria were the most common factors that contributed to deterioration in acute kidney injury.Acute kidney injuryRisk of renal failure injury to kidney failure and loss of function and end-stage kidney disease criteriaSepsisSerum creatinineJournal ArticleIndiaDepartment of Medicine, SRM Medical College Hospital and Research Centre, SRM IST, Kattankulathur, Tamil Nadu, IndiaDepartment of Medicine, Meenakshi Medical College Hospital and Research Institute, Enathur, Tamil Nadu, India
