Prevalence and factors associated with acute kidney injury in patients in intensive care units - Revista Brasileira de Enfermagem

ABSTRACT

Objectives:

to identify the prevalence and factors associated with the development of acute kidney injury in critically ill patients.

Methods:

a cross-sectional study, conducted from June 2018 to August 2019. The Kidney Disease Improving Global Outcomes was used to classify acute kidney injury. A significant value was set at p<0.05.

Results:

a total of 212 patients were included, of whom 35.8% evolved into an acute kidney injury. Patients with acute kidney injury had hypertension, higher levels on severity scores and a higher baseline creatinine rate> 1.5 mg/dL, also, when applied logistic regression, were 7 times more likely to develop acute kidney injury, Odds Ratio 7.018. More than half (56.6%) of the patients with acute kidney injury died. Moreover, 26.7% of these patients developed pressure sore.

Conclusions:

the prevalence of kidney injury was high (35.8%). The patients who developed it had a higher severity, mortality, and pressure sore index.
