Study of the value of bishop score in predicting preterm labor at The National Hospital of Obstetrics and Gynecology from 01/03/2013 to 01/09/2013

Abstract

Objective: Prospective study of 167 cases of threatened preterm labor who were treated in pathological obstetric department of the national hospital of obtestrics and gynecology from 01/03/2013 to 01/09/2013 . Objective: Assess the value of Bishop score in predicting preterm labor. Subjects and Methods : the patients were diagnosed and treated of threatened preterm birth in pathological obstetric department, are full of essential information. The prospective study and data analysis by SPSS 16.0 program. Calculate the average value, the percentage, comparing the two average values, sensitivity, specificity and ROC construction . Results and discussion: The Bishop score of ≥ 6 points has predictive value for preterm birth (sensitivity of 76,3% and specificity of 93,5%). The Threshold of predicting preterm birth within 72 hours for Bishop score is ≥ 9 points ( sensitivity of 46,67 % and a specificity of 95 % ). Conclusions: The Bishop score of ≥ 6 points has predictive value for preterm birth. The threshold for predicting preterm birth within 72 hours for Bishop score is ≥ 9 points.
