Investigation of acute kidney injury and related factors in hospital patients; single center experience

Abstract

Objectives: Acute Kidney Injury (AKI) is a very common clinical problem. This picture is seen in 5-7% of hospitalized patients and in 25-30% of patients hospitalized in intensive care units. The aim of this study was to determine the incidence, etiology, clinical features, prognosis and complications in adult patients hospitalized with of AKI.
 Methods: This study was organized as an observation study in which the files of the patients admitted to internal medicine and nephrology clinics between September 2012 and September 2017 were examined. All patients admitted to the internal medicine and nephrology clinics with the diagnosis of AKI were included in the study. But those under the age of 18, patients with chronic kidney damage, ex-patients after hospitalization, patients who were sent to the intensive care unit after hospitalization, patients who voluntarily refused treatment or left the service and who were hospitalized for more than 48 hours, but those who did not have biochemical analysis during their stay were excluded. RIFLE creatinine criteria were used for AKI identification.
 Results: The study included 354 patients. 177 (50%) patients were male and 177 (50%) patients were female. The incidence of prerenal AKI in the internal medicine and nephrology clinics was 53.39%, renal AKI was 36.44% and postrenal AKI was 10.17%. When the causes of AKI were examined, 33.9% hypovolemia, 15.5% UTI and 13.5% gastroenteritis were detected. The dialysis rate was 23.7%.
 Conclusion: Inconclusion, although the incidence of AKI is acceptable in our hospital. It is found to be compatible with the literature and it is possible to catch the early stage of injury by decreasing the frequency especially with better management of elderly patients and more closely monitoring renal functions in this group of patients.
