title: [Design of obstetrical "potential severe disease" score and its application in 3269 pregnant women].
abstract: OBJECTIVE
  To study the applicability and practicability of "potential severe disease" score in prognosticating severity of potential disease in late pregnancy and puerperal mother and newborn.
  
  
  METHODS
  "Potential severe disease" score was designed based on the characters of obstetrical patients, and 3269 puerperal women were surveyed and the condition of mother and child were investigated after delivery.
  
  
  RESULTS
  The mean rank of "potential severe disease" score in the group with severe illness (n=137) was extremely higher than that of smooth pregnancy group (n=3132, 2969.390 vs. 1576.630, Z=-18.052, P<0.01). The result indicated the score could evaluate the degree of illness. The area under the receiver operating characteristic curve (AUC) of the "potential severe disease" score was 0.926, the optimal cut-off point of score was 3, with sensibility 73.72%, specificity 92.21%. There was no significant difference in the mean rank of "potential severe disease" score between fetal distress group (n=507) and normal fetus group (n=2726, 1572.920 vs. 1646.400, Z=-1.498, P>0.05), therefore it indicated that the "potential severe disease" score had not the identification ability on fetal distress.
  
  
  CONCLUSIONS
  Obstetrical "potential severe disease" score may be applied for obstetrics because of speediness, simplicity and better identification in evaluating the disease in late pregnancy.
