Background: The barriers to comprehensive abortion care in Australian metropolitan tertiary hospitals are under-researched. Previous work has suggested that negative practitioner attitudes and lack of training may play a large role; however, this remains poorly understood.

Aim: The aim was to survey doctors practicing obstetrics and gynaecology to better understand their views, training experience and confidence in abortion care.

Method: The method involved a cross-sectional study via an anonymous survey at a single metropolitan tertiary hospital not providing substantive abortion services in Melbourne, Australia. Inclusion criterion was obstetric and gynaecology medical staff working at that hospital. Data were collected regarding views, training experiences and confidence in first-trimester medical and surgical abortion, and second-trimester surgical abortion. Data were analysed according to levels of training, categorised as RANZCOG (Royal Australian and New Zealand College of Obstetricians and Gynaecologists) Fellows, prevocational/vocational trainees and general practitioner specialists.

Results: Sixty-one valid responses were received from 90 eligible participants (response rate 68%). An overwhelming majority (96%) supported abortion services. The majority of RANZCOG Fellows felt confident performing first-trimester surgical abortion (89%) and first-trimester medical abortion (71%); however, only half felt confident performing second-trimester surgical abortion (50%). Prevocational/vocational trainees were overall less confident but overwhelmingly expressed interest in gaining further experience in abortion.

Conclusion: Doctors are generally confident in providing first-trimester abortion services (medical or surgical) in the metropolitan tertiary setting. However, further work is required to understand ongoing barriers to comprehensive abortion care. There may also be a skills shortage for second-trimester surgical abortion, requiring significant improvements in abortion training.

Guidelines for the investigation and management of recurrent pregnancy loss (RPL) have been developed in Europe, USA and UK, but there is currently no Australasian guideline. The Australasian Certificate of Reproductive Endocrinology and Infertility Consensus Expert Panel on Trial Evidence group has prepared a two-part guideline to provide guidance on the management of RPL. In Part I chromosomal, anatomical, and endocrine factors are outlined along with relevant recommendations for clinical management, levels of evidence and grades of consensus. In Part II thrombophilia, autoimmune factors, infective, inflammatory, and endometrial causes, environmental and lifestyle factors, male factor and unexplained causes will be outlined.

Part II of the Australasian guideline for the investigation and management of recurrent pregnancy loss (RPL) provides evidence-based guidance on the management of RPL provided. The implications of inherited and acquired thrombophilia with respect to RPL and suggestions for clinical management are provided. Autoimmune factors, including human leukocyte antigen, cytokines, antinuclear antibodies and coeliac antibodies, and guidance for management are discussed. Infective, inflammatory and endometrial causes of RPL are discussed in detail. Environmental and lifestyle factors, male factor and unexplained causes are outlined. Levels of evidence and grades of consensus are provided for all evidence-based statements.

Persistent pelvic pain is a significant healthcare concern among adolescents; however adolescents often have poor health literacy regarding their pain. Current school curricula fail to specifically address pelvic pain and management strategies. This review aims to summarise current pelvic pain education programs in Australian and New Zealand schools. These programs have successfully strengthened the understanding of the psychosocial impact of periods and pelvic pain, instilled greater confidence in managing persistent pain and have allowed for prompt detection and treatment of pelvic pain in adolescents. An outcomes-driven, collaborative, and coordinated approach is needed to improve pelvic health educational interventions for adolescents.

Background: Thyroid axis dysregulation during controlled ovarian hyperstimulation (COH) is more pronounced in hypothyroid-treated women. Whether or not this leads to compromised thyroid hormone levels within the ovarian follicular fluid is not known.

Aims: To determine whether ovarian follicular thyroid hormone levels are compromised in adequately replaced hypothyroid women undergoing controlled ovarian hyperstimulation (COH), and/or influence cycle/pregnancy outcomes.

Materials and methods: Prospective cohort study involving 46 euthyroid (anti-thyroid peroxidase antibody negative) and 16 levothyroxine-replaced women with baseline thyroid-stimulating hormone (TSH) <2.5 mIU/L attending their first COH cycle. Follicular fluid TSH, free triiodothyronine (T3) and free thyroxine (T4) were recorded at oocyte pick-up. Serum levels were measured at: (i) baseline; (ii) human chorionic gonadotropin trigger day; and (iii) cycle conclusion. The number of mature oocytes retrieved, fertilisation, early pregnancy loss and live birth rates were compared.

Results: Median serum TSH levels were similar at baseline (1.76 vs 1.24 mIU/L, P = 0.053), but free T3 levels were lower (4.5 vs 4.8 pmol/L, P = 0.029) in levothyroxine-replaced compared to euthyroid women, with serum TSH levels increasing across ovarian stimulation (P = 0.006) into pregnancy testing (P = 0.030). Follicular fluid free T3 levels were lower in levothyroxine-replaced women (median 4.3 vs 4.6 pmol/L, P = 0.032). Fertilisation rates were lower (52% vs 71%, P = 0.043) in women requiring levothyroxine replacement, but numbers of mature oocytes retrieved, early pregnancy loss and live births did not differ.

Conclusion: Adequately replaced hypothyroid women achieve lower ovarian follicular fluid free T3 levels and poorer fertilisation rates compared to euthyroid women undergoing COH. Optimising T3 levels may be pivotal in improving COH outcomes in hypothyroid women.

Background: The Society of Australia and New Zealand (SOMANZ) published its first sepsis in pregnancy and the postpartum period guideline in 2017 (Aust N Z J Obstet Gynaecol, 57, 2017, 540). In the intervening 6 years, maternal mortality from sepsis has remained static.

Aims: To update clinical practice with a review of the subsequent literature. In particular, to review the definition and screening tools for the diagnosis of sepsis.

Materials and methods: A multi-disciplinary group of clinicians with experience in all aspects of the care of pregnant women analysed the clinical evidence according to the GRADE (Grading of Recommendations Assessment, Development and Evaluation) system following searches of Cochrane, Medline and EMBASE. Where there were conflicting views, the authors reviewed the topic and came to a consensus. All authors reviewed the final position statement.

Results: This position statement has abandoned the use of the quick Sequential Organ Failure Assessment score (qSOFA) score to diagnose sepsis due to its poor performance in clinical practice. Whilst New Zealand has a national maternity observation chart, in Australia maternity early warning system charts and vital sign cut-offs differ between states. Rapid recognition, early antimicrobials and involvement of senior staff remain essential factors to improving outcomes.

Conclusion: Ongoing research is required to discover and validate tools to recognize and diagnose sepsis in pregnancy. Australia should follow New Zealand and have a single national maternity early warning system observation chart.

Background: Inter-observer agreement for the American Association of Gynecologic Laparoscopists (AAGL) 2021 Endometriosis Classification staging system has not been described. Its predecessor staging system, the revised American Society for Reproductive Medicine (rASRM), has historically demonstrated poor inter-observer agreement.

Aims: We aimed to determine the inter-observer agreement performance of the AAGL 2021 Endometriosis Classification staging system, and compare this with the rASRM staging system.

Materials and methods: A database of 317 patients with coded surgical data was retrospectively analysed. Three independent observers allocated AAGL surgical stages (1-4), twice. Observers made their own interpretation of how to apply the tool in the first staging allocation. Consensus rules were then developed for a second staging allocation.

Results: First staging allocation: odds ratio (OR) (and 95% CI) for observer 1 to score higher than observer 2 was 8.08 (5.12-12.76). Observer 1 to score higher than observer 3 was 12.98 (7.99-21.11) and observer 2 to score higher than observer 3 was 1.61 (1.03-2.51). This represents poor agreement. Second staging allocation (after consensus): OR for observer 1 to score higher than observer 2 was 1.14 (0.64-2.03), observer 1 to score higher than observer 3 was 1.81 (0.99-3.28) and observer 2 to score higher than observer 3 was 1.59 (0.87-2.89). This represents good agreement.

Conclusions: These findings suggest that in its current format the AAGL 2021 Endometriosis Classification staging system has poor inter-observer agreement, not superior to the rASRM staging system. However, performance improved when additional measures were taken to simplify and clarify areas of ambiguity in interpreting the staging system.

In August 2016, MSI Australia (MSIA) brought to scale a direct-to-patient telehealth medication abortion service. We used MSIA's patient management systems from January 2015 to December 2018 to assess changes in the proportion of abortion patients obtaining care after 13 weeks' gestation, proportion of abortion patients obtaining medication abortion versus procedural abortion and proportion of abortion patients from regional and remote versus metropolitan areas. The proportions of abortion patients obtaining care before 13 weeks' gestational duration and those from regional and remote residents did not change between the pre- and post-periods. We observed an increase in medication abortion use that was greater among those in regional and remote areas than those in metropolitan areas.

Aims: Postpartum length of stay (LOS) in Australian hospitals has reduced over the past three decades. Although a reduction in LOS likely reduces hospital costs in the immediate postpartum period, there is concern that this is increasing the burden on emergency services, domiciliary staff and primary care providers. The aims were to determine whether the recent reduction in LOS at an Australian tertiary obstetric hospital resulted in a change in emergency department (ED) presentations by women in the first six weeks postpartum, and newborns within the first 28 days of life.

Methods: We conducted a cross-sectional cohort study of all newborns ≤28 days of age and women ≤6 weeks postpartum who presented to the ED during four comparable time periods (2019-2022) at an Australian tertiary obstetric hospital. Logistic regression was used to determine the relationship between neonatal and maternal postpartum ED presentations and year of birth.

Results: Reduced postpartum LOS was associated with a significant increase in maternal and neonatal presentations to the ED (odds ratio (OR): 1.15 (95% confidence interval (CI): 1.08-1.23), and OR: 1.11 (95% CI: 1.03-1.19), respectively). For every 100 births, an extra six women and three neonates presented to the ED for postpartum care in 2022 compared with 2019. There was no difference in maternal or neonatal admissions throughout the study periods.

Conclusion: The increase in maternal and neonatal ED presentations associated with reduced LOS should prompt reassessment of postnatal practice and encourage further research into allocation of in-hospital resources and postpartum education.
