ABSTRACT
BACKGROUND:
A greater understanding of the risk factors for spontaneous preterm birth and the importance of risk stratification to guide interventions has led to the introduction of preterm birth prevention clinics.AIM:
To evaluate the experience and outcomes of the first specialised preterm birth clinic in New Zealand. MATERIALS ANDMETHODS:
This observational study reviewed pregnancies cared for in a preterm birth clinic from 2013 to 2018. Cases were identified and data collected from a maternity database and electronic medical records. Analysis was by referral type.RESULTS:
A total of 423 cases were included; 309 elective and 22 acute referrals in pregnancy, and 92 consultations outside pregnancy. For those referred electively in pregnancy, 138/309 (44.7%) fulfilled multiple referral criteria, and 57/309 (18.4%) had ≥2 previous spontaneous preterm births or second trimester losses. Excluding five pregnancies with first trimester miscarriage, 77/304 (25.3%) were managed with a history-indicated cerclage (11 placed pre-conception) and 217/304 (71.4%) had cervical surveillance as primary management, of which 133 (61.3%) did not require treatment. The remaining had treatment for a short cervix; 37 (17.0%) received an ultrasound-indicated cerclage only, 21 (9.7%) vaginal progesterone only and 26 (12.0%) both. Five women (1.6%) had a second trimester loss at 13+0 -19+6 and 58/297 (19.5%) had a spontaneous preterm birth at 20+0 -36+6 weeks. The 'take home baby' rate was 95.4%.CONCLUSIONS:
Pregnancy outcomes were similar to those reported by other preterm birth prevention clinics. The majority of women who received cervical surveillance as primary management were able to avoid additional treatment.Palavras-chave
