Objective: To investigate the epidemiology of acute kidney injury and to clarify the risk factors associated with the prognosis of acute kidney injury in critically ill patients in the Gansu Province.Methods : This was a multicenter, retrospective study. The clinical data of all patients from January 1, 2017, to December 31, 2019, in the intensive care unit of the selected hospitals were screened. Descriptive statistical analysis was performed first, and then the patients were divided into a survival group and a nonsurvival group based on survival status at discharge. Logistic regression analyses were used to determine the risk factors for in-hospital mortality in patients with acute kidney injury. RESULTS : (1) Among the 8106 patients admitted, a total of 3019 patients were excluded according to the exclusion criteria. Among the included patients, 890 patients met the diagnostic criteria for AKI, with an incidence of 17.5% and mortality of 41.3%. The etiology of acute kidney injury was 64% prerenal, 33% renal, and 2.7% postrenal. Prerenal AKI was the most common, among which cases caused by sepsis and septic shock accounted for 44.7%. Among the selected AKI patients, AKI stage I accounted for 22.02%, AKI stage II accounted for 31.01%, AKI stage III accounted for 46.97%, and 35.8% of the AKI patients received renal replacement therapy. (2) Logistic regression analysis showed that sex , age, AKI stage, RRT, infection, cardio-pulmonary resuscitation, cardiac output, mechanical ventilation, diuretics, white blood cells, platelets, blood urea nitrogen, prothrombin time and activated partial thromboplastin time were significantly associated with the prognosis of acute kidney injury (P |
