title: Possible association between screening BV at the prenatal visit and reduced cervical cerclage: multi-center questionnaire in Hokkaido, Japan.
abstract: OBJECTIVE
  To study the screening frequency for cervical cancer, Chlamydia trachomatis (CT) infection, and bacterial vaginosis (BV) among pregnant women, and to study the association between administration of these three screening tests and performance of cervical cerclage (CC) in Hokkaido during 2004.
  
  
  METHODS
  Questionnaires were mailed to 70 clinics providing prenatal care only and to 113 hospitals providing prenatal care and performing deliveries. Responses were obtained anonymously.
  
  
  RESULTS
  A total of 6744 pregnant women received prenatal care at the 36 responding clinics and 24 050 deliveries were performed at the 56 hospitals. The percentage of clinics that screened all pregnant women for cervical cancer, CT infection or BV was 66.7%, 69.4% and 33.3%, respectively, and the corresponding percentages among the hospitals were 87.5%, 87.5% and 57.1%, respectively. Pregnant women found to have CT infection or BV, were all treated. Screening for cervical cancer or CT infection was not associated with the frequency of CC. On the other hand, screening for BV was significantly associated with the frequency of CC (P = 0.0006). The frequency of emergency CC was 0.8% among women who received prenatal care at hospitals that did not perform BV screening, while it was only 0.2 or 0.3% among women who received prenatal care at hospitals that performed BV screening on all pregnant women or on those women who were suspected of having BV, respectively.
  
  
  CONCLUSIONS
  Our results suggest that the frequency of emergency CC may be reduced in women who receive BV screening and subsequent treatment of positive cases during pregnancy.
