title: Research of the assessable method of postpartum hemorrhage.
abstract: BACKGROUND
  Postpartum hemorrhage (PPH) is the most common cause of parturient death worldwide [1]. However, most cases of PPH can be avoided.
  
  
  OBJECTIVE
  This paper employs statistical methods to screen risk factors of PPH and calculate relevant parameters.
  
  
  METHODS
  Multivariable logistic regression analysis was applied to obtain the regression equation and odds ratio (OR) value. The determined risk factors were assigned comprehensive and reasonable scores according to scientific relevance and reasoning according to the OR value. PPPH values were calculated in order to assess the morbidity of PPH.
  
  
  RESULTS
  The scores of pregnant women could be intuitively used to show the risk of getting PPH.
  
  
  CONCLUSIONS
  Through the above methods, a comprehensive risk evaluation method of detecting PPH was developed.
