Modified Maddrey's discriminant function
The modified Maddrey's discriminant function) was originally described by Maddrey and Boitnott[1] to predict prognosis in alcoholic hepatitis. It is calculated by a simple formula:
![{\displaystyle {4}.{6}\times \ \left[prothombin\ time\ -\ control\ value\ (seconds)\right]\ +\ serum\ bilirubin\ (mg/dl)\,}](/media/api/rest_v1/media/math/render/svg/51cc0a759760950317cae888120cd7a540a70fc8)
Prospective studies have shown that, it is useful in predicting short term prognosis especially mortality within 30 days[2]. A value more than 32 implies poor outcome with one month mortality ranging between 35% to 45%[3].
To calculate Maddrey discriminant function using SI units - micromol/l (ie not US) divide bilirubin value by 17.
