title: [Pronostic risk assessment of delivery, in patients admitted for threatened preterm birth, in a tertiary care maternity center].
abstract: OBJECTIVE
  To assess preterm birth rate, in patients admitted for threatened preterm birth (TPB) in a tertiary care maternity center and evaluate our diagnostic and therapeutic tools.
  
  
  METHODS
  A retrospective cohort study, in a tertiary care maternity center (Marseille, France), reviewed all admissions for TPB from January 1 to December 31, 2009.
  
  
  RESULTS
  We recorded 224 admissions for TPB (181 single pregnancies and 43 twin pregnancies), 43.8% of TPB admissions were from materno-fetal transfer. Preterm birth rate was 44.9% (n=89), 39% (n=66) for single pregnancy and 76.6% (n=23) for twins. The 15 mm threshold for transvaginal sonography cervical length (CL) was the most relevant to predict the risk of preterm delivery, 77.3% (85/110) of patients with CL>15 mm having full term delivery.
  
  
  CONCLUSIONS
  For single pregnancy, most of the patients with cervical length>15 mm have full term delivery. It seems important to us to develop the use of more efficient predictive markers of risk-premature labor in order to improve the diagnosis and management of TPB.
