[Evaluation of surveillance on the case fatality rates in patients with severe hepatitis and of its clinical application].

The prognosis of patients with severe hepatitis is related to the severity of the disease when they are admitted to hospital. We retrospectively analyzed the clinical and laboratory data of 201 cases of severe hepatitis with the method of logistic regression and had obtained 8 independent variables strongly affecting the prognosis to form the multiple regression discriminant equation. The eight independent variables are Pa, A/G, SB, BUN, Cr, hepatic encephalopathy, infection and digestive tract bleeding. We can get the values of care fatality rates from the equation. The degree of severity can be classified with the value. Treatment plans can be drawn out and clinical research grouping can be improved on the basis of the values.
