MIMICdb data inclusion flow for computing hourly-adjusted UO and AKI analysis. UO sources were categorized into four physiologic compartments of urine accumulation. The first measured volume in each compartment was treated as residual volume from before admission and was dropped. UO rates were calculated by identifying time intervals from the last known record in the same compartment as the durations of collection. Valid hourly-adjusted UO was computed only when the UO rate was present for most of the calendar hour. GU genitourinary, ICU intensive care unit, L left, R right, UO urine output.
