Increasing Incidence Rate of Cervical Cerclage in Pregnancy in Australia: A Population-Based Study.
OBJECTIVE
Data published from the United States have demonstrated that the use of cervical cerclage has fallen in the period 1998-2013. This is in contrast to recommendations in Australia. We examined this trend using data from the Australian Institute of Health and Welfare (AIHW).


METHODS
Retrospective population-based study.


METHODS
Data from the Australian Institute of Health and Welfare procedural database were used to determine the total number of cervical cerclage sutures inserted during the period 2004 to 2013. Population datasets were used to calculate age-stratified incidence rates of cerclage.


RESULTS
There was a significant increase in the rate of cervical cerclage in women aged 25 to 34 years and in the 35 years and older age group. The incidence of preterm birth was stable for gestations of 32 to 36 weeks, but slightly increased in the 20 to 27 week and 28 to 31 week gestational age groups. Further research into cervical cerclage and the use of vaginal progesterone for the prevention of preterm birth would be valuable.
