The Western Australian Preterm Birth Prevention Initiative was officially launched in November 2014. It demonstrated an initial decrease in the preterm birth rate in Western Australia. One of the key points of this initiative is the routine ultrasound measurement of the cervical length in mid-pregnancy.
The aim of this study was to evaluate the perceptions and attitudes of Western Australian women regarding transvaginal cervical length (TVCL) screening for preterm birth prevention.
Self-administered questionnaires were completed by pregnant women before and after their mid-trimester obstetric ultrasound. Maternal demographical and medical data were collected in addition to opinions of TVCL screening.
A total of 598 women participated with the maternal age range representative of the Western Australian obstetric population. There was a high rate of acceptance of TVCL imaging, with 2% of the 149 women declining a transvaginal ultrasound (TVU) offered in this study, 1.5% refusing a TVU in the past and 5.7% reporting that they would have a concern in having a TVU in the future. Women stated that they either had declined TVCL in the past (11%) or would decline in the future (30.7%) as they wanted to discuss the procedure with their clinician first, had been advised not to have a TVU by their clinician (11% in the past and 47.7% in the future) or felt uncomfortable with the operator (22% at a previous TVU and 34.4% in the future).
Pregnant women participating in this study had a high acceptance of TVCL screening for preterm birth prevention.
西澳大利亚早产预防计划于 2014 年 11 月正式启动。该计划显示西澳大利亚的早产率最初有所下降。该计划的一个关键点是在妊娠中期常规进行超声测量宫颈长度。
本研究旨在评估西澳大利亚妇女对预防早产的经阴道宫颈长度（TVCL）筛查的看法和态度。
在接受中期产科超声检查之前和之后，孕妇自行填写问卷。除了 TVCL 筛查的意见外，还收集了产妇人口统计学和医疗数据。
共有 598 名妇女参加了这项研究，其年龄范围代表了西澳大利亚的产科人群。对 TVCL 成像的接受率很高，在 149 名拒绝参加本研究提供的经阴道超声检查（TVU）的妇女中，有 2%的妇女过去拒绝过 TVU，1.5%的妇女过去报告过她们将来会担心做 TVU，5.7%的妇女报告说她们将来会担心做 TVU。妇女们表示，她们过去（11%）或将来（30.7%）曾拒绝过 TVCL，因为她们想先与医生讨论该程序，曾被医生建议不要进行 TVU（过去 11%，将来 47.7%），或对操作者感到不舒服（过去 22%，将来 34.4%）。
参与本研究的孕妇对预防早产的 TVCL 筛查有很高的接受度。
