"Ongoing access to real-time and accurate monitoring of urine output could improve management of critically ill patients."
Oliguria is an early predictor of higher mortality in critically ill patients
Applying the Acute Kidney Injury Network (AKIN) classification system criteria for UO and serum creatinine (sCr) values, they found that patients exclusively diagnosed by UO criterion had more frequent need for dialysis, longer length of ICU stay, and higher mortality rates than patients without AKI. The time to reach AKI diagnosis by the UO criterion was shorter than by sCr criterion, and that by applying both criteria, the incidence of AKI increased from 24% using SCr criterion alone to 52%.
The authors hypothesize that UO has not been a focus of renal biomarker studies because accurate, hourly UO measurements have been difficult to obtain, stating "urine flow measurements are time-consuming, as urine meters require manipulation, visual assessment, and manual data recording." (p.764)
