★ DoctorScribe — Complete Clinic Management
AKI staging, etiology workup, every visit
DoctorScribe tracks creatinine trends, computes KDIGO AKI stage, and shows FENa/FEUrea on the same screen — no more flipping calculators.
Clinical Disclaimer: FENa is unreliable in patients on diuretics, with CKD, glycosuria, bicarbonaturia, or contrast-induced AKI. Use FEUrea (<35% pre-renal) in those settings. Always integrate with clinical picture and urine microscopy. Always verify against your local prescribing reference and apply clinical judgment.
AKI workup, automated
DoctorScribe auto-computes FENa, FEUrea and AKI staging from your routine labs and flags the likely cause before the nephrology consult.
