Introduction: There has been increased use of both induction of labor (IOL) and cesarean section for women with term pregnancies in many high‐income countries, and a trend toward birth at earlier gestational ages. Existing evidence regarding the association between IOL and cesarean section for term pregnancies is mixed and conflicting, and little evidence is available on the differential effect at each week of gestation, stratified by parity. Material and methods: To explore the association between IOL and primary cesarean section for singleton cephalic pregnancies at term, compared with two definitions of expectant management (first: at or beyond the week of gestation at birth following IOL; and secondary: only beyond the week of gestation at birth following IOL), we performed analyses of population‐based historical cohort data on women who gave birth in one Australian state (Queensland), between July 1, 2012 and June 30, 2018. Women who gave birth before 37+0 or after 41+6 weeks of gestation, had stillbirths, no‐labor, multiple births (twins or triplets), non‐cephalic presentation at birth, a previous cesarean section, or missing data on included variables were excluded. Four sub‐datasets were created for each week at birth (37–40). Unadjusted relative risk, adjusted relative risk using modified Poisson regression, and their 95% confidence intervals were calculated in each sub‐dataset. Analyses were stratified by parity (nulliparas vs. parous women with a previous vaginal birth). Sensitivity analyses were conducted by limiting to women with low‐risk pregnancies. Results: A total of 239 094 women were included in the analysis, 36.7% of whom gave birth following IOL. The likelihood of primary cesarean section following IOL in a Queensland population‐based cohort was significantly higher at 38 and 39 weeks, compared with expectant management up to 41+6 weeks, for both nulliparas and paras with singleton cephalic pregnancies, regardless of risk status of pregnancy and definition of expectant management. No significant difference was found for nulliparas at 37 and 40 weeks; and for paras at 40 weeks. Conclusions: Future studies are suggested to investigate further the association between IOL and other maternal and neonatal outcomes at each week of gestation in different maternal populations, before making any recommendation.

Background: Maternity care is a high‐volume and high‐cost area of health care, which entails various types of service use throughout the course of the pregnancy. Thus, the aim of this study was to explore the most common reasons and related costs of health services used by women and babies from pregnancy to 12‐month postbirth. Methods: We used linked administrative data from one state of Australia, which contained all births in Queensland between 01/07/2017 and 30/06/2018. Descriptive analyses were used to identify the 10 most frequent reasons and related costs for accessing inpatient, outpatient, emergency department, and Medicare services. These are reported separately for women and babies in different periods. Results: We included 58,394 births in our data set. The results have highlighted that there was relatively uniform use of inpatient, outpatient, and Medicare services by women and babies, with the 10 most common services accounting for more than half of the total services accessed. However, the emergency department service use was more diverse. Medicare services accounted for the greatest volume (79.21%) of service events but only 10.21% of the overall funding, compared with inpatient services, which accounted for less volume (3.62%) but the highest amount of overall funding (75.19%). Conclusion: Study findings provide empirical evidence about the full spectrum of services used by birthing families and their babies, and could assist health providers and managers to understand the services women and infants actually access during pregnancy, birth, and postbirth.

Objective: To quantify the economic impact of upscaling access to continuity of midwifery carer, compared with current standard maternity care, from the perspective of the public health care system., Methods: We created a static microsimulation model based on a whole-of-population linked administrative data set containing all public hospital births in one Australian state (Queensland) between July 2017 to June 2018 (n = 37,701). This model was weighted to represent projected State-level births between July 2023 and June 2031. Woman and infant health service costs (inpatient, outpatient and emergency department) during pregnancy and birth were summed. The base model represented current standard maternity care and a counterfactual model represented two hypothetical scenarios where 50 % or 65 % of women giving birth would access continuity of midwifery carer. Costs were reported in 2021/22 AUD., Results: The estimated cost savings to Queensland public hospital funders per pregnancy were $336 in 2023/24 and $546 with 50 % access. With 65 % access, the cost savings were estimated to be $534 per pregnancy in 2023/24 and $839 in 2030/31. A total State-level annual cost saving of $12 million in 2023/24 and $19 million in 2030/31 was estimated with 50 % access. With 65 % access, total State-level annual cost savings were estimated to be $19 million in 2023/24 and $30 million in 2030/31., Conclusion: Enabling most childbearing women in Australia to access continuity of midwifery carer would realise significant cost savings for the public health care system by reducing the rate of operative birth., Competing Interests: Declaration of competing interest We have no conflict of interest to declare., (Copyright © 2024 The Author(s).

Background: Despite strong evidence of benefits and increasing consumer demand for homebirth, Australia has failed to effectively upscale it. To promote the adoption and expansion of homebirth in the public health care system, policymakers require quantifiable results to evaluate its economic value. To date, there has been limited evaluation of the financial impact of birth settings for women at low risk of pregnancy complications., Objective: This study aimed to examine the difference in inpatient costs around birth between offering homebirth in the public maternity system versus not offering public homebirth to selected women who meet low-risk pregnancy criteria., Methods: We used a whole-of-population linked administrative dataset containing all women who gave birth in Queensland (one Australian State) between 01/07/2012 and 30/06/2018 where publicly funded homebirth is not currently offered. We created a static microsimulation model to compare the inpatient cost difference for mother and baby around birth based on the women who gave birth between 01/07/2017 and 30/06/2018 (n = 36,314). The model comprised of a base model - representing standard public hospital care, and a counterfactual model - representing a hypothetical scenario where 5 % of women who gave birth in public hospitals planned to give birth at home prior to the onset of labour (n = 1816). Costs were reported in 2021/22 AUD., Results: In our hypothetical scenario, after considering the effect of assumptive place and mode of birth for these planned homebirths, the estimated State-level inpatient cost saving around birth (summed for mother and babies) per pregnancy were: AU$303.13 (to Queensland public hospitals) and AU$186.94 (to Queensland public hospital funders). This calculates to a total cost saving per annum of AU$11 million (to Queensland public hospitals) and AU$6.8 million (to Queensland public hospital funders)., Conclusion: A considerable amount of inpatient health care costs around birth could be saved if 5 % of women booked at their local public hospitals, planned to give birth at home through a public-funded homebirth program. This finding supports the establishment and expansion of the homebirth option in the public health care system., Competing Interests: Conflict of interest None declared., (Copyright © 2023 The Authors.

Background: Short birth intervals and unintended pregnancy are associated with poorer maternal and infant outcomes. There is a risk of pregnancy during the immediate postpartum period unless contraception is initiated. This retrospective cohort study aimed to capture the current patterns of hormonal contraceptive provision within 12 months postpartum in a high-income country., Methods: We used a linked administrative dataset comprising all women who gave birth in Queensland, Australia between 1 July 2012 and 30 June 2018 (n=339 265 pregnancies). We described our cohort by whether they were provided with government-subsidised hormonal contraception within 12 months postpartum. The associations between hormonal postpartum contraceptive provision and demographic and clinical characteristics were examined using univariate and multivariate logistic regression and presented in terms of crude and adjusted odds ratios with 95% confidence intervals., Results: A majority of women (60.2%) were not provided with government-subsidised hormonal postpartum contraception within 12 months postpartum. Women who were younger (<25 years), were overweight or obese, smoked, were born in Australia, were non-Indigenous, gave birth in a public hospital, or were in the lowest socioeconomic status group were more likely to be provided with postpartum contraception after adjusting for other covariates, compared with their counterparts., Conclusions: Strategies to increase the provision and uptake of contraception in the immediate postpartum period are needed to prevent short birth intervals and unintended pregnancy and ensure women's fertility intentions are enacted. Ongoing research is needed to examine the factors influencing women's access to contraceptive services and, further, the types of contraception provided., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.
