Objective To evaluate the Australian Capital Territory (ACT) Preterm Birth (PTB) Prevention Initiative and its effects on preterm and early term birth rates at the main tertiary hospital after 16 months of implementation. Design: A non-randomised before and after study, where the intervention was a multifaceted PTB prevention initiative. Setting: The main tertiary referral hospital in the ACT. Population: Women who birthed at the main tertiary hospital in the ACT in the pre and post intervention period. Methods: The PTB prevention initiative was implemented in 2019. Rates of early birth were assessed using run charts of bimonthly preterm and early term rates from 2014-2020. Main Outcomes measured: The main outcomes measured were rates of preterm and early term births before and after implementation of the PTB prevention initiative. Results: At the main tertiary hospital in the ACT, the rate of PTB was significantly reduced by 10% after 16 months of implementation of the initiative, corresponding to 45 averted or delayed PTBs. The number of iatrogenic early term births with no medical indication (NMI) was significantly reduced by 34.5% and resulted in 77 averted or delayed early term births. Conclusions: The multifaceted PTB prevention initiative safely lowered the rates of early birth in the ACT context. These results highlight the importance of prioritising early birth prevention, education, research and expanding the PTB Prevention Initiative nationwide.

Background A multifaceted preterm birth (PTB) prevention initiative was launched in the Australian Capital Territory (ACT) in 2019. The aim of this initiative was to safely lower the rate of early births across the ACT and the surrounding areas in New South Wales. Modelled on the Western Australian PTB Prevention Initiative, the program included new clinical guidelines and a new PTB prevention clinic at the main tertiary hospital. Aim To evaluate the initiative and its effects on preterm and early term birth rates at the main tertiary hospital after 16 months of implementation. Materials and Methods A before and after intervention study was conducted. Rates of preterm and early term birth before (previous five years) and after 16 months of implementation of the ACT PTB Prevention Initiative were evaluated. Results At the main tertiary hospital in The Canberra Hospital, the rate of PTB was significantly reduced by 10% after 16 months of implementation of the initiative. Rates of PTB were lower than any of the preceding five years and resulted in 45 averted or delayed PTBs. The number of planned early term births with no medical indication was significantly reduced by 34.5% and resulted in 77 averted or delayed early term births. Conclusions The multifaceted PTB Prevention Initiative safely lowered the rates of early birth in the ACT context. These results highlight the importance of prioritising early birth prevention, education, research and expanding the initiative nationwide.
