Program is based on the following: Estimating Creatinine Clearance (ml/min) Cockcroft and Gault equation: CrCl = (140 - age) x IBW / (Scr x 72) (x 0.85 for females)
Estimate Ideal body weight in (kg) Males: IBW = 50 kg + 2.3 kg for each inch over 5 feet. Females: IBW = 45.5 kg + 2.3 kg for each inch over 5 feet.
Jelliffe RW. Creatinine clearance: Bedside estimate. Ann Inter Med. 1973; 79:604. Male: (98 - (0.8 * (age - 20))) / SCR in (mg/dL) x Patients BSA/1.73 M2 Female: Multiply above result by 0.9
