Abstract:
Objective Acute kidney injury (AKI) is common but usually under-diagnosed in hospitalized patients,of the impact of which on patients is still unclear.The paper was aimed to investigate the impact of delayed recognition of AKI on short-time prognosis of patients through a propensity score matched study.Methods From Oct 2013 to Sep 2014,1401 adult hospitalized patients with AKI in the First Affiliated Hospital of Nanjing Medical University were divided into delayed recognition group and timely-diagnosed group according to propensity score matching (1∶ 1) without replacement method.Primary endpoint was 30-day all-cause mortality,and secondary endpoints included recovery of kidney at discharge,length of hospitalization,length of intensive care unit stay and hospital costs.Results There were significant differences in age,department distribution,complications,stage of AKI,Charlson index,APACHE Ⅱ score,SOFA score between the two groups before matching.After matching,there were no significant difference in demographic data,department distribution,complications,stage of AKI,Charlson index,APACHE Ⅱ score,SOFA score between the two groups except in blood urea nitrogen (P=0.039) and use of diuretics (P=0.018).Delayed recognition of acute kidney injury was not associated with 30-day all-cause mortality in univariate (P=0.711) and multivariate Logistic regression analyses.The secondary endpoints did not differ in two groups.Conclusion Delayed acute kidney injury recognition did not associate with poor short-term outcomes in adult hospitalized patients.
