Abstract:
Objective To evaluate the etiology,epidemiological characteristics,clinical diagnosis,and outcomes of hospitalized patients with AKI in Xinjiang,analyzing the risk factors of their clinical prognosis.Methods A multicenter retrospective survey was conducted,investigating adult patients admitted to four hospitals in Xinjiang in January and July 2013.Patients with AKI were screened out based on KDIGO's inclusion and exclusion criteria.Clinical variables of patients with AKI including demographics,clinical data,laboratory tests,treatment measures and prognosis were collected.Results Among 32,157 adult hospitalized patients,there were 722 AKI patients.Excluding those with incomplete data,719 patients were enrolled in this study.The detection rate of AKI was 2.25％ (722 of 32,157) by KDIGO criteria.The main cause for AKI was pre-renal injury,led mainly by cardiac output,low blood volume,and the use of nephrotoxic drugs.The non-recognition rate of AKI was 72.4％ (407/557).Multivariate binary logistic regression analysis showed that AKI stage,peripheral vasodilation and renal parenchyma were protective factors of the omission diagnosis.In the short-term prognostic analysis,the overall mortality rate was 12.8％(92/719).Among the 323 patients with AKI who survived discharge,43.7％(141) had renal function recovery;40.2％(130) did not fully recover their renal function but ceased maintenance dialysis;16.4％ (53) were still on dialysis at discharge.Multivariate Cox regression model suggested that DIC,shock and department of obstetrics were independent risk factors for death during hospitalization of AKI.In addition,the risk of death for AKI from department of obstetrics and gynecology patients was higher than that of other departments.Conclusions The most common reason for AKI in hospitalized patients in Xinjiang was pre-renal injury.The main risk factors were low cardiac output and low blood volume.The omission diagnosis of AKI was serious;AKI stage,peripheral vasodilation and renal parenchymal injury however were its protective factors.Poor-DIC,shock,hospitalization in obstetrics were independent risk factors for death in patients with AKI.
