title: [A single factor analysis of the prognosis of 301 hepatitis failure cases and a study of a scoring system on their prognostic assessment].
abstract: OBJECTIVE
  To analyze the factors related to prognosis of hepatitis failure and to determine the factors which significantly affect it, and to build a scoring system for assessment of the prognosis of hepatitis failure and also to examine its efficacy for clinical use.
  
  
  METHODS
  Clinical data from 301 patients were analyzed retrospectively. The correlated degree between those single factors and prognosis of hepatitis failure was explored by logistic regression analysis. Independent risk factors of prognosis and those correlated coefficients, which were from logistic regression analysis, were used to build a scoring system. This system was used in analyzing the clinical data of 275 patients to examine its efficacy of the prognostic assessment.
  
  
  RESULTS
  The factors that significantly affected the prognosis of hepatitis failure included age, clinical typing, hepatic coma, total bilirubin, and others (P < 0.01). Some factors, including PTA, blood urea, sodium and hepatic coma, were independent risk factors of prognosis. The scoring system built gave different scores between the effective treatment group and ineffective treatment group with statistical significance (P < 0.01). When the score was less than 40, the probability of a recovery was 76.9%; when the score was 40 to 80, the probability of a recovery was only 12.5%. When the score was more than 80, the probability of a recovery dropped to 0%.
  
  
  CONCLUSIONS
  The factors, including PTA, blood urea and sodium and hepatic coma, are important in building a scoring system to assess the prognosis of hepatitis failure. The scoring system we built is very effective in evaluating the prognosis of hepatitis failure.
