Assign points for each predictor, then sum to obtain the Licurse score (0-10 points):

Predictor	Definition (per original model)	Points
History of hydronephrosis	Previous hydronephrosis documented on imaging before the current AKI episode. A yes answer contributes 4 points, placing the patient in the high-risk band.	4
Recurrent urinary tract infections	Recurrent UTIs noted in the record, or at least 2 UTIs in the year before admission.	1
Diagnosis consistent with possible obstruction	Clinical history suggesting obstruction, such as abdominal or pelvic mass, benign prostatic hypertrophy, prior pelvic surgery, or neurogenic bladder.	1
Non-Black race	Race variable used in the original model; apply cautiously and follow local equity policy.	1
No inpatient nephrotoxic medications	No exposure during this admission to nephrotoxic agents such as aspirin above 81 mg/day, diuretics, ACE inhibitors, or vancomycin.	1
No congestive heart failure	No documented CHF.	1
No prerenal AKI features	No sepsis or vasopressor use associated with the AKI episode in the primary model definition.	1

Risk groups: 0-2 low risk, 3 medium risk, and ≥4 high risk.
