Externally validated prediction models for pre-eclampsia: systematic review and meta-analysis

OBJECTIVE

This systematic review and meta-analysis aimed to evaluate the performance of existing externally validated prediction models for pre-eclampsia (PE) (specifically, any-onset, early-onset, late-onset and preterm PE).

METHODS

A systematic search was conducted in five databases (MEDLINE, EMBASE, Emcare, CINAHL and Maternity & Infant Care Database) and using Google Scholar/reference search to identify studies based on the Population, Index prediction model, Comparator, Outcome, Timing and Setting (PICOTS) approach until 20 May 2023. We extracted data using the CHARMS checklist and appraised the risk of bias using the PROBAST tool. A meta-analysis of discrimination and calibration performance was conducted when appropriate.

RESULTS

Twenty-three studies reported 52 externally validated prediction models for PE (one preterm, 20 any-onset, 17 early-onset and 14 late-onset PE models). No model had the same set of predictors. Fifteen any-onset PE models were validated externally once, two were validated twice and three were validated three times, while the Fetal Medicine Foundation (FMF) competing-risks model for preterm PE prediction was validated widely in 16 different settings. The most common predictors were maternal characteristics (prepregnancy body mass index, prior PE, family history of PE, chronic medical conditions and ethnicity) and biomarkers (uterine artery pulsatility index and pregnancy-associated plasma protein-A). The FMF model for preterm PE (triple test plus maternal factors) had the best performance, with a pooled area under the receiver-operating-characteristics curve (AUC) of 0.90 (95% prediction interval (PI), 0.76-0.96), and was well calibrated. The other models generally had poor-to-good discrimination performance (median AUC, 0.66 (range, 0.53-0.77)) and were overfitted on external validation. Apart from the FMF model, only two models that were validated multiple times for any-onset PE prediction, which were based on maternal characteristics only, produced reasonable pooled AUCs of 0.71 (95% PI, 0.66-0.76) and 0.73 (95% PI, 0.55-0.86).

CONCLUSIONS

Existing externally validated prediction models for any-, early- and late-onset PE have limited discrimination and calibration performance, and include inconsistent input variables. The triple-test FMF model had outstanding discrimination performance in predicting preterm PE in numerous settings, but the inclusion of specialized biomarkers may limit feasibility and implementation outside of high-resource settings. © 2023 The Authors.

Likelihood of primary cesarean section following induction of labor in singleton cephalic pregnancies at term, compared with expectant management: An Australian population-based, historical cohort study

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.

Identifying Longer-Term Health Events and Outcomes and Health Service Use of Low Birthweight CALD Infants in Australia

INTRODUCTION

Approximately one-third of all births in Australia each year are by culturally and linguistically diverse (CALD) women. CALD women are at an increased risk of adverse pregnancy and birth outcomes including prematurity and low birthweight. Infants born weighing less than 2500 g are susceptible to increased risk of ill health and morbidities such as cognitive defects including cerebral palsy, and neuro-motor functioning.

METHODS

An existing linked administrative dataset, Maternity 1000 was utilized for this study which has identified all children born in Queensland (QLD), Australia, between 1st July 2012 to 30th June 2018 from the QLD Perinatal Data Collection. This has then been linked to the QLD Hospital Admitted Patient Data Collection, QLD Hospital Non-Admitted Patient Data Collection, QLD Emergency Department Data Collection, and Medicare Benefits Schedule and Pharmaceutical Benefits Scheme Claims Records between 1 and 2012 to 30th June 2019.

RESULTS

Culturally and linguistically diverse infants born with low birthweight had higher mean and standard deviation of all health events and outcomes; potentially preventable hospitalisations, hospital re-admissions, ED presentations without admissions, and development of chronic diseases compared to non-CALD infants born with low birthweight.

DISCUSSION

Results from this study highlight the disparities in health service use and health events and outcomes associated with low birthweight infants, between both CALD and Australian born women. This study has responded to the knowledge gap of low birthweight on the Australian economy by identifying that there are significant inequalities in access to health services for CALD women in Australia, as well as increased health events and poor birth outcomes for these infants when compared to those of mothers born in Australia.

Midwife-led birthing centres in Bangladesh, Pakistan and Uganda: an economic evaluation of case study sites

INTRODUCTION

Achieving the Sustainable Development Goals to reduce maternal and neonatal mortality rates will require the expansion and strengthening of quality maternal health services. Midwife-led birth centres (MLBCs) are an alternative to hospital-based care for low-risk pregnancies where the lead professional at the time of birth is a trained midwife. These have been used in many countries to improve birth outcomes.

METHODS

The cost analysis used primary data collection from four MLBCs in Bangladesh, Pakistan and Uganda (n=12 MLBC sites). Modelled cost-effectiveness analysis was conducted to compare the incremental cost-effectiveness ratio (ICER), measured as incremental cost per disability-adjusted life-year (DALY) averted, of MLBCs to standard care in each country. Results were presented in 2022 US dollars.

RESULTS

Cost per birth in MLBCs varied greatly within and between countries, from US$21 per birth at site 3, Bangladesh to US$2374 at site 2, Uganda. Midwife salary and facility operation costs were the primary drivers of costs in most MLBCs. Six of the 12 MLBCs produced better health outcomes at a lower cost (dominated) compared with standard care; and three produced better health outcomes at a higher cost compared with standard care, with ICERs ranging from US$571/DALY averted to US$55 942/DALY averted.

CONCLUSION

MLBCs appear to be able to produce better health outcomes at lower cost or be highly cost-effective compared with standard care. Costs do vary across sites and settings, and so further exploration of costs and cost-effectiveness as a part of implementation and establishment activities should be a priority.

Applying a simplified economic evaluation approach to evaluate infertility treatments in clinical practice

IVF is the backbone of infertility treatment, but due to its costs, it is not affordable for everyone. The cost of IVF is further escalated by interventions added to the routine treatment, which are claimed to boost pregnancy rates, so-called add-ons. Consequently, it is critical to offset the increased costs of an intervention against a potentially higher benefit. Here, we propose using a simplified framework considering the cost of a standard IVF procedure to create one live-born baby as a benchmark for the cost-effectiveness of other fertility treatments, add-ons inclusive. This framework is a simplified approach to a formal economic evaluation, enabling a rapid assessment of cost effectiveness in clinical settings. For a 30-year-old woman, assuming a 44.6% cumulative live birth rate and a cost of $12 000 per complete cycle, the cost to create one live-born baby would be ∼$27 000 (i.e. willingness to pay). Under this concept, the decision whether to accept or reject a new treatment depends from an economic perspective on the incremental cost per additional live birth from the new treatment/add-on, with the $27 000 per live-born baby as a reference threshold. This threshold can vary with women's age, and other factors such as the economic perspective and risk of side effects can play a role. If a new add-on or treatment costs >$27 000 per live birth, it might be more rational to invest in a new IVF cycle rather than spending on the add-on. With the increasing number of novel technologies in IVF and the lack of a rapid approach to evaluate their cost-effectiveness, this simplified framework will help with a more objective assessment of the cost-effectiveness of infertility treatments, including add-ons.

Intrapartum use of sildenafil citrate to prevent fetal compromise and emergency operative birth in term pregnancies in the United Kingdom and Australia: A preliminary cost-effectiveness analysis

OBJECTIVE

To compare cost-effectiveness of oral sildenafil citrate, administered after onset of labor, with standard care to health system funders in the UK and Australia.

METHODS

We conducted a modeled cost-effectiveness analysis, measuring costs and quality adjusted life years (QALYs), using a decision-analytic model covering onset of labor to 1 month post-birth. The relative risk of emergency cesarean section and operative vaginal birth was taken from a Phase 2 placebo controlled double blinded randomized control trial.

RESULTS

Both options of care resulted in the same QALYs gained over the model time period (0.08). Sildenafil citrate was cost-saving compared with standard care, saving £92 per birth in the UK (AU$303 per birth in Australia). Sensitivity analyses did not identify any areas of uncertainty that stopped sildenafil citrate being cost saving compared with standard care. Threshold analysis revealed that sildenafil citrate would be cost saving up to a per birth drug or administration cost of £152.32 in the UK (AU$333.61 in Australia).

CONCLUSION

Oral sildenafil citrate may be cost saving compared with standard care; however, the effects on neonatal outcomes still need to be demonstrated in large randomized trials.

The value of maternity care in Queensland, 2012-18, based on an analysis of administrative data: a retrospective observational study

OBJECTIVE

To quantify the value of maternity health care - the relationship of outcomes to costs - in Queensland during 2012-18.

STUDY DESIGN

Retrospective observational study; analysis of Queensland Perinatal Data Collection data linked with the Queensland Health Admitted Patient, Non-Admitted Patient, and Emergency Data Collections, and with the Medicare Benefits Schedule (MBS) and Pharmaceutical Benefits Scheme (PBS) databases.

SETTING, PARTICIPANTS

All births in Queensland during 1 July 2012 - 30 June 2018.

MAIN OUTCOME MEASURES

Maternity care costs per birth (reported in 2021-22 Australian dollars), both overall and by funder type (public hospital funders, MBS, PBS, private health insurers, out-of-pocket costs); value of care, defined as total cost per positive birth outcome (composite measure).

RESULTS

The mean cost per birth (all funders) increased from $20 471 (standard deviation [SD], $17 513) during the second half of 2012 to $30 000 (SD, $22 323) during the first half of 2018; the annual total costs for all births increased from $1.31 billion to $1.84 billion, despite a slight decline in the total number of births. In a mixed effects linear analysis adjusted for demographic, clinical, and birth characteristics, the mean total cost per birth in the second half of 2018 was $9493 higher (99.9% confidence interval, $8930-10 056) than during the first half of 2012. The proportion of births that did not satisfy our criteria for a positive birth outcome increased from 27.1% (8404 births) during the second half of 2012 to 30.5% (9041 births) during the first half of 2018.

CONCLUSION

The costs of maternity care have increased in Queensland, and many adverse birth outcomes have become more frequent. Broad clinical collaboration, effective prevention and treatment strategies, as well as maternal health services focused on all dimensions of value, are needed to ensure the quality and viability of maternity care in Australia.

Designing economic evaluations alongside clinical trials in maternal health care: A guide for clinical trial design

BACKGROUND

Economic evaluations are being conducted with increasing frequency in the maternity care setting, with more randomized controlled trials containing a health economic component. Key emerging criticisms of economic evaluation in maternity care are lack of robust data collection and measurement, inconsistencies in methodology, and lack of adherence to reporting guidelines.

METHODS

This article provides a guide to the design of economic evaluations alongside clinical trials in maternal health. We include economic concepts and considerations for the maternity setting and provide examples from the UK and Australia.

RESULTS

There are many important considerations for the design of economic evaluations alongside clinical trials. To be effective, researchers must select types of economic evaluation, which align with their study objectives; choose an appropriate evaluation perspective, time horizon, and discount rate; and identify accurate ways to measure and evaluate health outcomes and costs.

DISCUSSION

This guide is written for noneconomists and can be used for designing economic evaluations to be conducted as a part of clinical trials. We seek to improve the quality, consistency, and transparency of economic evaluations in maternal health.

Development, women-centricity and psychometric properties of maternity patient-reported outcome measures (PROMs): A systematic review

BACKGROUND

Measuring maternity care outcomes based on what women value is critical to promoting woman-centred maternity care. Patient-reported outcome measures (PROMs) are instruments that enable service users to assess healthcare service and system performance.

AIM

To identify and critically appraise the risk of bias, woman-centricity (content validity) and psychometric properties of maternity PROMs published in the scientific literature.

METHODS

MEDLINE, CINAHL Plus, PsycINFO and Embase were systematically searched for relevant records between 01/01/2010 and 07/10/2021. Included articles underwent risk of bias, content validity and psychometric properties assessments in line with COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) guidance. PROM results were summarised according to language subgroups and an overall recommendation for use was determined.

FINDINGS

Forty-four studies reported on the development and psychometric evaluation of 9 maternity PROMs, grouped into 32 language subgroups. Risk of bias assessments for the PROM development and content validity showed inadequate or doubtful methodological quality. Internal consistency reliability, hypothesis testing (for construct validity), structural validity and test-retest reliability varied markedly in sufficiency and evidence quality. No PROMs received a level 'A' recommendation, required for real-world use.

CONCLUSION

Maternity PROMs identified in this systematic review had poor quality evidence for their measurement properties and lacked sufficient content validity, indicating a lack of woman-centricity in instrument development. Future research should prioritise women's voices in deciding what is relevant, comprehensive and comprehensible to measure, as this will impact overall validity and reliability and facilitate real-world use.

Development, woman-centricity and psychometric properties of maternity patient-reported experience measures: a systematic review

OBJECTIVE

Valid and reliable maternity patient-reported experience measures are critical to understanding women's experiences of care. They can support clinical practice, health service and system performance measurement, and research. The aim of this review is to identify and critically appraise the risk of bias, woman-centricity (content validity), and psychometric properties of maternity patient-reported experience measures published in the scientific literature.

DATA SOURCES

MEDLINE, CINAHL Plus, PsycINFO, and Embase were systematically searched for relevant records between January 1, 2010 and July 10, 2021.

STUDY ELIGIBILITY CRITERIA

We searched for articles describing the instrument development of maternity patient-reported experience measures and measurement properties associated with instrument validity and reliability testing. Articles that described patient-reported experience measures developed outside of the maternity context and articles that did not contribute to the instruments' development, content validation, and/or psychometric evaluation were excluded.

METHODS

Included articles underwent risk of bias, content validity, and psychometric properties assessments in line with the COSMIN (COnsensus-based Standards for the selection of health Measurement INstruments) guidance. Patient-reported experience measure results were summarized according to language subgroups. An overall recommendation for use was determined for each patient-reported experience measure language subgroup.

RESULTS

A total of 54 studies reported on the development and psychometric evaluation of 25 maternity patient-reported experience measures, grouped into 45 language subgroups. The quality of evidence underpinning the instruments' development was generally poor. Only 2 (4.4%) patient-reported experience measures reported sufficient content validity, and only 1 (2.2%) received a level "A" recommendation, required for real-world use.

CONCLUSION

Maternity patient-reported experience measures demonstrated poor-quality evidence for their measurement properties and insufficient detail about content validity. Future maternity patient-reported experience measure development needs to prioritize women's involvement in deciding what is relevant, comprehensive, and comprehensible to measure. Improving the content validity of maternity patient-reported experience measures will improve overall validity and reliability and facilitate real-world practice improvements. Standardized patient-reported experience measure implementation also needs to be prioritized to support advancements in clinical practice for women.

Long-term cost-effectiveness of implementing a lifestyle intervention during pregnancy to reduce the incidence of gestational diabetes and type 2 diabetes

AIMS/HYPOTHESIS

The aim of this study was to determine the long-term cost-effectiveness and return on investment of implementing a structured lifestyle intervention to reduce excessive gestational weight gain and associated incidence of gestational diabetes mellitus (GDM) and type 2 diabetes mellitus.

METHODS

A decision-analytic Markov model was used to compare the health and cost-effectiveness outcomes for (1) a structured lifestyle intervention during pregnancy to prevent GDM and subsequent type 2 diabetes; and (2) current usual antenatal care. Life table modelling was used to capture type 2 diabetes morbidity, mortality and quality-adjusted life years over a lifetime horizon for all women giving birth in Australia. Costs incorporated both healthcare and societal perspectives. The intervention effect was derived from published meta-analyses. Deterministic and probabilistic sensitivity analyses were used to capture the impact of uncertainty in the model.

RESULTS

The model projected a 10% reduction in the number of women subsequently diagnosed with type 2 diabetes through implementation of the lifestyle intervention compared with current usual care. The total net incremental cost of intervention was approximately AU$70 million, and the cost savings from the reduction in costs of antenatal care for GDM, birth complications and type 2 diabetes management were approximately AU$85 million. The intervention was dominant (cost-saving) compared with usual care from a healthcare perspective, and returned AU$1.22 (95% CI 0.53, 2.13) per dollar invested. The results were robust to sensitivity analysis, and remained cost-saving or highly cost-effective in each of the scenarios explored.

CONCLUSIONS/INTERPRETATION

This study demonstrates significant cost savings from implementation of a structured lifestyle intervention during pregnancy, due to a reduction in adverse health outcomes for women during both the perinatal period and over their lifetime.

Value in maternal care: Using the Learning Health System to facilitate action

There is an increasing need to deliver high-value health care. Here, we discuss how value should be measured and implemented in maternity care through a Learning Health System. High-value maternity care will produce the highest level of benefit for women at a given cost. As pregnancy is not an illness state, and there is no cure or remission to be achieved, we believe that patient-reported outcomes should be an integral component of benefit quantification when measuring value. Furthermore, as care impacts more than just health outcomes-particularly in maternity care-there is also a need to consider patient-reported experiences as a part of defining the level of benefit. However, to move beyond traditional narrow and passive measurement of value, we need to partner with stakeholders to identify priorities for change, identify evidence for how to achieve this change, integrate measurement activities, and promote effective implementation, in a continuous, learning cycle-a Learning Health System. A robust Framework for implementing a Learning Health System has been developed, which could be applied in maternity care.

Development of a co-designed, evidence-based, multi-pronged strategy to support normal birth

Australia's caesarean section (CS) rate has been steadily increasing for decades. In response to this, we co-designed an evidence-based, multi-pronged strategy to increase the normal birth rate in Queensland and reduce the need for CS. We conducted three workshops with a multi-stakeholder group to identify a broad range of options to reduce CS, prioritise these options, and achieve consensus on a final strategy. The strategy comprised of: universal access to midwifery continuity-of-care and choice of place of birth; multi-disciplinary normal birth education; resources to facilitate informed decision-making; respectful maternity care and positive workplace culture; and establishment of a Normal Birth Collaborative.

How does the onset of physical disability or dementia in older adults affect economic wellbeing and co-payments for health care? the impact of gender

BACKGROUND

Existing studies have illustrated how the onset of physical disability or dementia negatively impacts economic wellbeing and increases out of pocket costs. However, little is known about this relationship in older individuals. Consequently, this study aimed to identify how the onset of physical disability or dementia in older adults affects economic wellbeing and out of pocket costs, and to explore the impact of gender in the context of Australia.

METHODS

The data was collected from a large, randomized clinical study, ASPirin in Reducing Events in the Elderly (ASPREE). Two generalized linear models (with and without interaction effects) of total out of pocket costs for those who did and did not develop physical disability or dementia were generated, with adjustment for sociodemographic characteristics at baseline.

RESULTS

We included 8,568 older Australian individuals with a mean age of 74.8 years and 53.2% being females. After adjustment for the baseline sociodemographic characteristics, the onset of physical disability did statistically significantly raise out of pocket costs (cost ratio = 1.25) and costs among females were 13.1% higher than males.

CONCLUSIONS

This study highlights that classifying different types of health conditions to identify the drivers of out of pocket costs and to explore the gender differences in a long-term follow-up is of importance to examine the financial impact on the older population. These negative financial impacts and gender disparities of physical disability and dementia must be considered by policymakers.

Inequities in vulnerable children’s access to health services in Australia

Introduction

Children born into families at risk of becoming or remaining poor are at significant risk of experiencing childhood poverty, which can impair their start to life, and perpetuate intergenerational cycles of poverty. This study sought to quantify health service utilisation, costs and funding distribution amongst children born into vulnerable compared to non-vulnerable families.

Methods

This study used a large linked administrative dataset for all women giving birth in Queensland, Australia between July 2012 and July 2018. Health service use included inpatient, emergency department (ED), general practice, specialist, pathology and diagnostic imaging services. Costs included those paid by public hospital funders, private health insurers, Medicare and out-of-pocket costs.

Results

Vulnerable children comprised 34.1% of the study cohort. Compared with non-vulnerable children, they used significantly higher average numbers of ED services during the first 5 years of life (2.52±3.63 vs 1.97±2.77), and significantly lower average numbers of specialist, pathology and diagnostic imaging services. Vulnerable children incurred significantly greater costs to public hospital funders compared with non-vulnerable children over the first 5 years of life ($16 053 vs $10 247), and significantly lower private health insurer, Medicare and out-of-pocket costs.

Conclusion

There are clear inequities in vulnerable children’s health service utilisation in Australia. Greater examination of the uptake and cost-effectiveness of maternal and child services is needed, as these services support children’s development in the critical first 1000 days of life.

Inequality in early childhood chronic health conditions requiring hospitalisation: A data linkage study of health service utilisation and costs

BACKGROUND

The cost of socioeconomic inequality in health service use among Australian children with chronic health conditions is poorly understood.

OBJECTIVES

To quantify the cost of socioeconomic inequality in health service use among Australian children with chronic health conditions.

METHODS

Cohort study using a whole-of-population linked administrative data for all births in Queensland, Australia, between July 2015 and July 2018. Socioeconomic status was defined by an areas-based measure, grouping children into quintiles from most disadvantaged (Q1) to least disadvantaged (Q5) based on their postcode at birth. Study outcomes included health service utilisation (inpatient, emergency department, outpatient, general practitioner, specialist, pathology and diagnostic imaging services) and healthcare costs.

RESULTS

Of the 238,600 children included in the analysis, 10.4% had at least one chronic health condition. Children with chronic health conditions in Q1 had higher rates of inpatient (6.6, 95% confidence interval [CI] 6.4, 6.7), emergency department (7.2, 95% CI 7.0, 7.5) and outpatient (20.3, 95% CI 19.4, 21.3) service use compared to children with chronic health conditions in Q5. They also had lower rates of general practitioner (37.5, 95% CI 36.7, 38.4), specialist (8.9, 95% CI 8.5, 9.3), pathology (10.7, 95% CI 10.2, 11.3), and diagnostic imaging (4.3, 95% CI 4.2,4.5) service use. Children with any chronic health condition in Q1 incurred lower median out-of-pocket fees than children in Q5 ($0 vs $741, respectively), lower median Medicare funding ($2710, vs $3408, respectively), and higher median public hospital funding ($31, 052 vs $23, 017, respectively).

CONCLUSIONS

Children of most disadvantage are more likely to access public hospital provided services, which are accessible free of charge to patients. These children are less likely to access general practitioner, specialist, pathology and diagnostic imaging services; all of which are critical to the ongoing management of chronic health conditions, but often attract an out-of-pocket fee.

Quantifying the differences in birth outcomes and out-of-pocket costs between Australian Defence Force servicewomen and civilian women: A data linkage study

OBJECTIVES

Servicewomen in Defence Forces the world over are constrained in their health service use by defence healthcare policy. These policies govern a woman's ability to choose who she receives maternity care from and where. The aim of this study was to compare Australian Defence Force (ADF) servicewomen and children's birth outcomes, health service use, and out-of-pocket costs to those of civilian women and children.

METHODS

Retrospective cohort study using linked administrative data for women giving birth between 1 July 2012 and 30 June 2018 in Queensland, Australia (n = 365,138 births). Women serving in the ADF at the time of birth were identified as having their care funded by the Department of Defence (n = 395 births). Propensity score matching was used to identify a mixed public/private civilian sample of women to allow for comparison with servicewomen, controlling for baseline characteristics. Sensitivity analysis was also conducted using a sample of civilian women accessing only private maternity care.

FINDINGS

Nearly all servicewomen gave birth in the private setting (97.22%). They had significantly greater odds of having a caesarean section (OR 1.71, 95%CI 1.29-2.30) and epidural (OR 1.56, 95%CI 1.11-2.20), and significantly lower odds of having a non-instrumental vaginal birth (OR 0.57, 95%CI 0.43-0.75) compared to women in the matched public/private civilian sample. Compared to civilian children, children born to servicewomen had significantly higher out-of-pocket costs at birth ($275.93 ± 355.82), in the first ($214.98 ± 403.45) and second ($127.75 ± 391.13) years of life, and overall up to two years of age ($618.66 ± 779.67) despite similar health service use.

CONCLUSIONS

ADF servicewomen have higher rates of obstetric intervention at birth and also pay significantly higher out-of-pocket costs for their children's health service utilisation up to 2-years of age. Given the high rates of obstetric intervention, greater exploration of servicewomen's maternity care experiences and preferences is warranted, as this may necessitate further reform to ADF maternity healthcare policy.

Cost of intimate partner violence during pregnancy and postpartum to health services: a data linkage study in Queensland, Australia

To quantify health service costs of intimate partner violence (IPV) during pregnancy and postpartum; and to compare health service costs between women who reported IPV, versus women who did not report IPV. This was a cohort study using linked data for a publicly funded Australian tertiary hospital maternity service. Participants included all women accessing antenatal services between August 2016 and August 2018. Routinely collected IPV data were linked to women's admitted, non-admitted, emergency department, perinatal, and costing data from 6 months prior to reporting IPV through to 12 months post-birth. Of the 9889 women receiving maternity care, 280 (2.9%) reported some form of IPV with 72 (24.8%) referred to support. Women who reported IPV generated higher mean total costs than women not reporting IPV ($12,772 vs $10,166, respectively). Between-group differences were significant after adjusting for demographic and clinical factors (cost ratio 1.24, 95% CI: 1.15-1.34). There were no significant differences in mean total costs for babies where IPV was and was not reported ($4971 vs $5340, respectively). IPV is costly for health services. However, greater research is needed to comprehensively estimate the long-term health service costs associated with IPV. Furthermore, the limitations associated with routinely collected IPV data suggest that standardised screening practices and innovative data linkage and modelling approaches are required to collect data that truly represents the burden and costs associated with IPV.

The healthcare needs of preterm and extremely premature babies in Australia-assessing the long-term health service use and costs with a data linkage cohort study

The health conditions associated with extreme prematurity will likely require life-long treatment and management. As such, planning for the provision of healthcare services is essential in order to maximise their long-term well-being. We sought to quantify the use of healthcare services and the associated costs for extremely premature babies compared to preterm and term babies in Australia using a whole-of-population linked administrative dataset. In the first year of life, extremely premature babies had an average of 3.4 hospital admissions, and 2 emergency department presentations. They also had an average of 16 specialist attendances, 33 pathology tests and 6 diagnostic imaging tests performed. This was more than that utilised by preterm and full-term babies. The mean annual cost of hospitalisations was $182,312 for extremely premature babies in the first year and $9958 in the second year. The mean annual out-of-pocket fees for these services were $2212 and $121 in the first and second years respectively.Conclusion: Understanding the long-term healthcare needs of extremely premature babies in order to provide both an adequate number of services and also connection between services should be a central part of health system planning as the survival rates of extremely premature babies improve over time. What is Known: • The health service use of extremely premature babies is higher at the time of birth. • Health conditions and disabilities associated with extreme prematurity require life-long care. What is New: • Extremely premature babies have more diverse and frequent access to services than premature and term babies until at least age 2. • This comes at higher cost to families through out-of-pocket payments.

Cost-effectiveness of public caseload midwifery compared to standard care in an Australian setting: a pragmatic analysis to inform service delivery

BACKGROUND

Decision-makers need quantifiable data on costs and outcomes to determine the optimal mix of antenatal models of care to offer. This study aimed to examine the cost utility of a publicly funded Midwifery Group Practice (MGP) caseload model of care compared to other models of care and demonstrate the feasibility of conducting such an analysis to inform service decision-making.

OBJECTIVE

To provide a methodological framework to determine the value of public midwifery in different settings.

METHODS

Incremental costs and incremental utility (health gains measured in quality-adjusted life years (QALYs)) of public MGP caseload were compared to other models of care currently offered at a large tertiary hospital in Australia. Patient Reported Outcomes Measurement Information System Global Short Form scores were converted into utility values by mapping to the EuroQol 5 dimensions and then converting to QALYs. Costs were assessed from a health system funder's point of view.

RESULTS

There were 85 women in the public MGP caseload care group and 72 received other models of care. Unadjusted total mean cost for mothers' and babies' health service use from study entry to 12 months post-partum was $27 618 for MGP caseload care and $33 608 for other models of care. After adjusting for clinical and demographic differences between groups, total costs were 22% higher (cost ratio: 1.218, P = 0.04) for other models of maternity care. When considering costs to all funders, public MGP caseload care cost $5208 less than other models of care. There was no significant difference in QALY between the two groups (difference: 0.010, 95% CI: -0.038, 0.018).

CONCLUSION

Public MGP caseload care costs 22% less than other models of care, after accounting for differences in baseline characteristics between groups. There were no significant differences in QALYs. Public MGP caseload care produced comparable health outcomes, with some indication that outcomes may be better for lower cost per woman.

Postnatal Major Depressive Disorder in Australia: Inequalities and Costs of Healthcare to Individuals, Governments and Insurers

BACKGROUND

Perinatal mental health has pervasive impacts on the wellbeing of both the mother and child, affecting quality of life, bonding and attachment and cognitive development.

OBJECTIVES

The aim of this study was to (i) quantify the costs to government healthcare funders, private health insurers and individuals through out-of-pocket fees, of women with postnatal major depressive disorder (MDD); and (ii) identify any socioeconomic inequalities in health service use and costs amongst these women.

METHODS

A whole-of-population linked administrative dataset containing the clinical records and health service use for all births in the state of Queensland, Australia between 01 July 2012 and 30 June 2015 was used (n = 189,081). Postnatal MDD was classified according to ICD-10 code, with women hospitalised for MDD in the 12 months after birth classified as having 'postnatal MDD' (n = 728). Health service use and costs from birth to 12 months post-birth were included. Total costs included cost to government funders and private health insurers and out-of-pocket fees. Total costs and costs to different funders were compared for women with postnatal MDD and for women without an inpatient event for postnatal MDD, with unadjusted means presented. A generalised linear model was used to compare the difference in total costs, adjusting for key confounders. Costs to different funders and number of different services accessed were then compared for women with postnatal MDD by socioeconomic status, with unadjusted means presented.

RESULTS

The total costs from birth to 12 months post-birth were 636% higher for women with postnatal MDD than women without an inpatient event for postnatal MDD, after accounting for differences in private hospital use, mode of birth, clinical characteristics and socioeconomic status. Amongst women with postnatal MDD, the cost of all services accessed was higher for women of highest socioeconomic status than for women of lowest socioeconomic status (A$15,787.66 vs A$11,916.94). The cost of services for women of highest socioeconomic status was higher for private health insurers (A$8941.25 vs A$2555.26), but lower for public hospital funders (A$2423.39 vs A$6582.09) relative to women of lowest socioeconomic status. Outside of public hospitals, costs to government funders was higher for women of highest socioeconomic status (A$2766.80 vs A$1952.00). Women of highest socioeconomic status accessed more inpatient (8.2 vs 3.1) and specialist services (13.4 vs 5.5) and a higher proportion had access to psychiatric specialist care (39.7% vs 13.6%) and antidepressants (97.6% vs 93.8%).

CONCLUSION

MDD is costly to all funders of healthcare. Amongst women with MDD, there are large differences in the types of services accessed and costs to different funders based on socioeconomic status. There may be significant financial and structural barriers preventing equal access to care for women with postnatal MDD.

The opportunity costs of birth in Australia: Hospital resource savings for a post-COVID-19 era

BACKGROUND

COVID-19 caused significant disruptions to health systems globally; however, restricting the family presence during birth saw an increase in women considering community birth options. This study aimed to quantify the hospital resource savings that could occur if all low-risk women in Australia gave birth at home or in birth centers.

METHODS

A whole-of-population linked administrative data set containing all women (n = 44 498) who gave birth in Queensland, Australia, between 01/07/2012 and 30/06/2015 was reweighted to represent all Australian women giving birth in 2017. A static microsimulation model of woman and infant health service resource use was created based on 2017 data. The model was comprised of a base model, representing "current" care, and a counterfactual model, representing hypothetical scenarios where all low-risk Australian women gave birth at home or in birth centers.

RESULTS

If all low-risk women gave birth at home in 2017, cesarean rates would have reduced from 13.4% to 2.7%. Similarly, there would have been 860 fewer inpatient bed days and 10.1 fewer hours of women's intensive care unit time per 1000 births. If all women gave birth in birth centers, cesarean rates would have reduced to 6.7%. In addition, over 760 inpatient bed days would have been saved along with 5.6 hours of women's intensive care unit time per 1000 births.

CONCLUSIONS

Significant health resource savings could occur by shifting low-risk births from hospitals to home birth and birth center services. Greater examination of Australian women's preferences for home birth and birth center birth models of care is needed.

Health service use and health system costs associated with diabetes during pregnancy in Australia

BACKGROUND AND AIMS

In the context of the rising rate of diabetes in pregnancy in Australia, this study aims to examine the health service and resource use associated with diabetes during pregnancy.

METHODS AND RESULTS

This project utilised a linked administrative dataset containing health and cost data for all mothers who gave birth in Queensland, Australia between 2012 and 2015 (n = 186,789, plus their babies, n = 189,909). The association between maternal characteristics and diabetes status were compared with chi-square analyses. Multiple logistic regression produced the odds ratio of having different outcomes for women who had diabetes compared to women who did not. A two-sample t-test compared the mean number of health services accessed. Generalised linear regression produced the mean costs associated with health service use. Mothers who had diabetes during pregnancy were more likely to have their labour induced at <38 weeks gestation (OR:1.39, 95% CI:1.29-1.50); have a cesarean section (OR: 1.26, 95% CI:1.22-1.31); have a preterm birth (OR:1.24, 95%: 1.18-1.32); have their baby admitted to a Special Care Nursery (OR: 2.34, 95% CI:2.26-2.43) and a Neonatal Intensive Care Unit (OR:1.25, 95%CI: 1.14-1.37). On average, mothers with diabetes access health services on more occasions during pregnancy (54.4) compared to mothers without (50.5). Total government expenditure on mothers with diabetes over the first 1000 days of the perinatal journey was significantly higher than in mothers without diabetes ($12,757 and $11,332).

CONCLUSION

Overall, mothers that have diabetes in pregnancy require greater health care and resource use than mothers without diabetes in pregnancy.

Inequality in out of pocket fees, government funding and utilisation of maternal health services in Australia

This study aimed to assess the distribution of service utilisation, out-of-pocket fees and government funding for maternal health care in Australia by socioeconomic group. A large linked administrative dataset was utilised. Women were grouped into socioeconomic quintiles using an area-based measure of socioeconomic status. Descriptive statistics were used to quantify the distribution of number of services, out of pocket fees, and government funding by socioeconomic quintile. Needs-adjusted concentration indices (CI_NA) were utilised to quantify inequity. The mean out of pocket fees for women of least socioeconomic advantage was $1,026 and for women of most socioeconomic advantage the mean was $2,432 (CI_NA 0.093, 95% CI: 0.088 - 0.098). However, use of many services were higher for women of most socioeconomic advantage: private obstetrician (CI_NA: 0.035, 95% CI: 0.032 - 0.038), other specialist services (CI_NA: 0.089, 95%CI: 0.083 - 0.094), and diagnostic and pathology tests (CI_NA: 0.027, 95%CI: 0.025 - 0.030). Federal government funding through Medicare was distributed towards women of most socioeconomic advantage (CI_NA: 0.036, 95%CI: 0.033 - 0.039); whereas government public hospital funding was skewed towards women of least socioeconomic advantage (CI_NA: -0.05, 95%CI: -0.057 - -0.046). Future policy changes in Australia's healthcare system need to ensure that women of least socioeconomic advantage have adequate access to maternity and early childhood care, and out of pocket fees are not an access barrier.

Health inequality in the tropics and its costs: a Sustainable Development Goals alert

Background

It is known that health impacts economic performance. This article aims to assess the current state of health inequality in the tropics, defined as the countries located between the Tropic of Cancer and the Tropic of Capricorn, and estimate the impact of this inequality on gross domestic product (GDP).

Methods

We constructed a series of concentration indices showing between-country inequalities in disability-adjusted life years (DALYs), taken from the Global Burden of Disease Study. We then utilized a non-linear least squares model to estimate the influence of health on GDP and counterfactual analysis to assess the GDP for each country had there been no between-country inequality.

Results

The poorest 25% of the tropical population had 68% of the all-cause DALYs burden in 2015; 82% of the communicable, maternal, neonatal and nutritional DALYs burden; 55% of the non-communicable disease DALYs burden and 61% of the injury DALYs burden. An increase in the all-cause DALYs rate of 1/1000 resulted in a 0.05% decrease in GDP. If there were no inequality between countries in all-cause DALY rates, most high-income countries would see a modest increase in GDP, with low- and middle-income countries estimated to see larger increases.

Conclusions

There are large and growing inequalities in health in the tropics and this has significant economic cost for lower-income countries.

Differential access to continuity of midwifery care in Queensland, Australia

ObjectiveTo determine maternal access to continuity of midwifery care in public maternity hospitals across the state of Queensland, Australia. MethodsMaternal access to continuity of midwifery care in Queensland was modelled by considering the proportion of midwives publicly employed to provide continuity of midwifery care alongside 2017 birth data for Queensland Hospital and Health Services. The model assumed an average caseload per full-time equivalent midwife working in continuity of care with 35 women per annum, based on state Nursing and Midwifery Award conditions. Hospitals were grouped into five clusters using standard Australian hospital classifications. ResultsTwenty-seven facilities (out of 39, 69%) across all 15 hospital and health services in Queensland providing a maternity service offered continuity of midwifery care in 2017 (birthing onsite). Modelling applying the assumed caseload of 35 women per full-time equivalent midwife found wide variations in the percentage of women able to access continuity of midwifery care, with access available for an estimated 18% of childbearing women across the state. Hospital classifications with higher clinical services capability and birth volume did not equate with higher access to continuity of midwifery care in metropolitan areas. Regional health services with level 3 district hospitals assisting with &lt;500 births showed higher levels of access, potentially due to additional challenges to meet local population needs to those of a metropolitan service. Access to full continuity of midwifery care in level 3 remote hospitals (&lt;500 births) was artificially inflated due to planned pre-labour transfers for women requiring specialised intrapartum care and women who planned to birth at other hospitals. ConclusionsDespite strong evidence that continuity of midwifery care offers optimal care for women and their babies, there was significant variation in implementation and scale-up of these models across hospital jurisdictions. What is known about the topic?Access to continuity of midwifery care for pregnant women within the public health system varies widely; however, access variation among different hospital classification groups in Australian states and territories has not been systematically mapped. What does this paper add?This paper identified differential access to continuity of midwifery care among hospital classifications grouped for clinical services capability and birth volume in one state, Queensland. It shows that higher clinical services capability and birth volume did not equate with higher access to continuity of midwifery care in metropolitan areas. What are the implications for practitionersScaling up continuity of midwifery care among all hospital classification groups in Queensland remains an important public health strategy to address equitable service access.

Cost of maternity care to public hospitals: a first 1000-days perspective from Queensland

Objective This study sought to compare costs for women giving birth in different public hospital services across Queensland and their babies. Methods A whole-of-population linked administrative dataset was used containing all health service use in a public hospital in Queensland for women who gave birth between 1 July 2012 and 30 June 2015 and their babies. Generalised linear models were used to compare costs over the first 1000 days between hospital and health services. Results The mean unadjusted cost for each woman and her baby (n = 134910) was A$17406 in the first 1000 days. After adjusting for clinical and demographic factors and birth type, women and their babies who birthed in the Cairns Hospital and Health Service (HHS) had costs 19% lower than those who birthed in Gold Coast HHS (95% confidence interval (CI) -32%, -4%); women and their babies who birthed at the Mater public hospitals had costs 28% higher than those who birthed at Gold Coast HHS (95% CI 8, 51). Conclusions There was considerable variation in costs between hospital and health services in Queensland for the costs of delivering maternity care. Cost needs to be considered as an important additional element of monitoring programs. What is known about the topic? The Australian maternal care system delivers high-quality, safe care to Australian mothers. However, this comes at a considerable financial cost to the Australian public health system. It is known that there are variations in the cost of care depending upon the model of care a woman receives, and the type of delivery she has, with higher-cost treatment not necessarily being safer or producing better outcomes. What does this paper add? This paper compares the cost of delivering a full cycle of maternity care to a woman at different HHSs across Queensland. It demonstrates that there is considerable variation in cost across HHSs, even after adjusting for clinical and demographic factors. What are the implications for practitioners? Reporting of cost should be an ongoing part of performance monitoring in public hospital maternity care alongside clinical outcomes to ensure the sustainability of the high-quality maternal health care Australian public hospitals deliver.

Disparities in access to health care in Australia for people with mental health conditions

Objective One aim of Australia's Equally Well National Consensus Statement is to improve monitoring of the physical health of people with mental health conditions, which includes measures of accessibility and people's experiences of physical health care services. The present analysis contributes to this aim by using population survey data to evaluate whether, and in what domains, Australians with a mental health condition experience barriers in accessing care when compared with Australians without a mental health condition. Methods The 2016 Commonwealth Fund International Health Policy Survey includes a sample of 5248 Australian adults. Access to care was measured using 39 survey questions from before to after reaching services. Multivariable logistic regression models were used to identify disparities in barriers to access, comparing experiences of people with and without a self-reported mental health condition, adjusting for age, sex, immigrant status, income and self-rated health. Results Australians with mental health conditions were more likely to experience barriers for 29 of 39 access measures (odds ratio (OR) >1.55; P<0.05). On average, the prevalence of barriers was 10 percentage points higher for those with a condition. When measured as ratios, the largest barriers for people with mental health conditions were for affordability. When measured as percentage point differences, the largest disparities were observed for experiences of not being treated with respect in hospital. Disparities remained after adjusting for income, rurality, education, immigrant status and self-rated health for 25 of 39 measures. Conclusion Compared with the rest of the community, Australians with mental health conditions have additional challenges negotiating the health system, and are more likely to experience barriers to access to care across a wide range of measures. Understanding the extent to which people with mental health conditions experience barriers throughout the pathway to accessing care is crucial to inform care planning and delivery for this vulnerable group. Results may inform improvements in regular performance monitoring of disparities in access for people with mental health conditions. What is known about this topic? A stated national aim of the Equally Well National Consensus Statement is to improve monitoring of the physical health and well-being of people with mental health conditions through measures of service accessibility and people's experiences of physical healthcare services. What does this paper add? This paper highlights areas in which health services are not providing equal access to overall care for people with mental health conditions. The analysis offers quantitative evidence of 'red flag areas' where people with mental health conditions are significantly more likely to experience barriers to access to care. What are the implications for practitioners? Systematic attention across the health system to making care more approachable and accessible for people with mental health conditions is needed. Practitioners may be engaged to discuss possible interventions to improve access disparities for people with mental health conditions.

The cost of Hypertensive Disorders of Pregnancy to the Australian healthcare system

In Australia, Hypertensive Disorders of Pregnancy are one of the leading causes of maternal death. Additionally, mothers and babies can experience significant morbidity associated with Hypertensive Disorders of Pregnancy. Currently, there is little understanding about the resources spent on this pregnancy complication in Australia. Therefore, using a linked administrative dataset from the Queensland population in Australia, this study aims to determine the difference in government expenditure between mothers that have Hypertensive Disorders of Pregnancy and mothers who do not. The total government expenditure on mothers that had HDP was significantly higher than in mothers who did not have HDP ($14,388 and $11,395 respectively). Most notably, the greatest difference in costs were experienced during the time of birth ($8696 and $6509).

Disparities in experiences of emergency department care for people with a mental health condition

BACKGROUND

The aim of this study was to explore differences in experiences of care in Emergency Departments (EDs) for people with and without mental health conditions.

METHODS

Secondary analyses of a survey of 15,995 patients from 82 EDs in New South Wales, Australia was conducted focusing on the most positive responses for 53 questions across nine dimensions of experiences. Logistic regression was used to compare experiences between people with and without a self-reported mental health condition, regardless of the reason for presentation.

RESULTS

Most patients reported positive experiences, with 60% rating care as 'very good'. However, fewer people with mental health conditions gave 'very good' ratings (52%). Their experiences were significantly less positive for 40 of 53 questions. For overall impressions of professionals, physical comfort, and continuity dimensions, experiences for those with mental health conditions were at least eight percentage points lower than those with no condition. Differences were minimal for other questions such as experiences with facilities (e.g. clean treatment areas).

CONCLUSIONS

Regardless of the reason for their visit, improvements in experiences for people with mental health conditions should focus on interactions with healthcare professionals, comfort, engagement and continuity. Improving experiences of this group can help improve their outcomes of care.

What are the costs of stillbirth? Capturing the direct health care and macroeconomic costs in Australia

BACKGROUND

Reducing stillbirth rates is an international priority; however, little is known about the cost of stillbirth. This analysis sought to quantify the costs of stillbirth in Australia.

METHODS

Mothers and costs were identified by linking a state-based registry of all births between 2012 and 2015 to other administrative data sets. Costs from time of birth to 2 years postbirth were included. Propensity score matching was used to account for differences between women who had a stillbirth and those that did not. Macroeconomic costs were estimated using value of lost output analysis and value of lost welfare analysis.

RESULTS

Cost to government was on average $3774 more per mother who had a stillbirth compared with mothers who had a live birth. After accounting for gestation at birth, the cost of a stillbirth was 42% more than a live birth (P < .001). Costs for inpatient services, emergency department services, services covered under Medicare (such as primary and specialist care, diagnostic tests and imaging), and prescription pharmaceuticals were all significantly higher for mothers who had a stillbirth. Mothers who had a stillbirth paid on average $1479 out of pocket, which was 52% more than mothers who had a live birth after accounting for gestation at birth (P < .001). The value of lost output was estimated to be $73.8 million (95% CI: 44.0 million-103.9 million). The estimated value of lost social welfare was estimated to be $18 billion.

DISCUSSION

Stillbirth has a sustained economic impact on society and families, which demonstrates the potential resource savings that could be generated from stillbirth prevention.

Experiences of maternity care in New South Wales among women with mental health conditions

Background

High quality maternity care is increasingly understood to represent a continuum of care. As well as ensuring a positive experience for mothers and families, integrated maternity care is responsive to mental health needs of mothers. The aim of this paper is to summarize differences in women’s experiences of maternity care between women with and without a self-reported mental health condition.

Methods

Secondary analyses of a randomized, stratified sample patient experience survey of 4787 women who gave birth in a New South Wales public hospital in 2017. We focused on 64 measures of experiences of antenatal care, hospital care during and following birth and follow up at home. Experiences covered eight dimensions: overall impressions, emotional support, respect for preferences, information, involvement, physical comfort and continuity. Multivariable logistic regression was used to compare experiences of women with and without a self-reported longstanding mental health condition.

Results

Compared to women without a condition, women with a longstanding mental health condition (n = 353) reported significantly less positive experiences by eight percentage points on average, with significant differences on 41 out of 64 measures after adjusting for age, education, language, parity, type of birth and region. Disparities were pronounced for key measures of emotional support (discussion of worries and fears, trust in providers), physical comfort (assistance, pain management) and overall impressions of care. Most women with mental health conditions (75% or more) reported positive experiences for measures related to guidelines for maternity care for women with mental illness (discussion of emotional health, healthy behaviours, weight gain). Their experiences were not significantly different from those of women with no reported conditions.

Conclusions

Women with a mental health condition had significantly less positive experiences of maternity care across all stages of care compared to women with no condition. However, for some measures, including those related to guidelines for maternity care for women with mental illness, there were highly positive ratings and no significant differences between groups. This suggests disparities in experiences of care for women with mental health conditions are not inevitable. More can be done to improve experiences of maternity care for women with mental health conditions.

Out-of-pocket expenditure on health care by Australian mothers: Lessons for maternal universal health coverage from a long-established system

BACKGROUND

Designing effective universal health care systems has challenges, including the use of patient co-payments and the role of the public and private systems. This study sought to quantify the total amount of out-of-pocket fees incurred by women who gave birth in private and public hospitals within Australia-a country with universal health coverage-and assess the impact that variation in birth type has on out-of-pocket fees.

METHODS

Data came from a linked administrative data set of all women who gave birth in the Australian state Queensland between July 1, 2012, and June 30, 2015, plus their resultant children. Propensity score matching was used to create two similar cohorts of women who gave birth in private and public hospitals.

RESULTS

The mean total out-of-pocket fees for care from conception to the child's first birthday was $2813 (±2683 standard deviation) and $623 (±1202) for women who gave birth in private and public hospitals, respectively. Total fees were higher in both public and private hospitals for women who had a cesarean birth ($716 [±1419] and $3010 [±2988]) than for women who had a vaginal birth without instruments ($556 [±1044] and $2560 [±2284]).

DISCUSSION

Australia's strong policy incentives for women to take out private health insurance are leaving women with large out-of-pocket costs. This should hold important lessons for other countries implementing a universal health care system, to ensure that using a combination of public and private practitioners does not undermine the intention of universal care.

Reducing caesarean delivery: An economic evaluation of routine induction of labour at 39 weeks in low-risk nulliparous women

BACKGROUND

Clinical interventions known to reduce the risk of caesarean delivery include routine induction of labour at 39 weeks, caseload midwifery and chart audit, but they have not been compared for cost-effectiveness.

OBJECTIVE

To assesses the cost-effectiveness of three different interventions known to reduce caesarean delivery rates compared to standard care; and conduct a budget impact analysis.

METHODS

A Markov microsimulation model was constructed to compare the costs and outcomes produced by the different interventions. Costs included all costs to the health system, and outcomes were quality-adjusted life years (QALY) gained. A budget impact analysis was undertaken using this model to quantify the costs (in Australian dollars) over three years for government health system funders.

RESULTS

All interventions, plus standard care, produced similar health outcomes (mean of 1.84 QALYs gained over 105 weeks). Caseload midwifery was the lowest cost option at $15 587 (95% confidence interval [CI] 15 269, 15 905), followed by routine induction of labour ($16 257, 95% CI 15 989, 16 536), and chart audit ($16 325, 95% CI 15 979, 16 671). All produced lower costs on average than standard care ($16 905, 95% CI 16 551, 17 259). Caseload midwifery would produce the greatest savings of $172.6 million over three years if implemented for all low-risk nulliparous women in Australia.

CONCLUSIONS

Caseload midwifery presents the best value for reducing caesarean delivery rates of the options considered. Routine induction of labour at 39 weeks and chart audit would also reduce costs compared to standard care.

Patient-reported outcome measurement in community-acquired pneumonia: feasibility of routine application in an elderly hospitalized population

Background

Community-acquired pneumonia (CAP) is a leading cause of morbidity and mortality worldwide, but few studies have evaluated the feasibility of routine patient-reported outcome measures (PROMs) in this illness. This study investigates the feasibility and limitations of three credible PROM instruments in a representative hospitalized cohort to identify potential barriers to routine application.

Methods

A sample of multimorbid hospitalized subjects meeting a standardized CAP definition was recruited. Demographic and clinical data of those able and unable to participate in PROM assessment were compared. The EQ-5D-5L, CAP-Sym 18 Questionnaire, and Late-Life Function and Disability Instrument (LLFDI) were administered (via face-to-face interview) at admission and discharge and (via phone interview or mail) at 30 and 90 days post-discharge. Feasibility measures included the proportion of individuals able to participate in assessment, attrition rates, data completeness, and instrument completion times. Scores at admission and 30 days post-discharge were examined for association with age.

Results

Of 82 subjects screened, 44 (54%) participated. Cognitive impairment (n = 12, 15%) commonly precluded participation. Seventeen (39%) participants were lost to follow-up by 90 days. Missing data at item level was negligible for all instruments, regardless of the mode of completion. Completion of the three instruments collectively in a face-to-face interview took a median of 17 min (IQ range 13-21) per participant. The burden of reported symptoms at admission was higher for younger participants aged 18-74 years (mean (standard deviation)) CAP-Sym 18 score at admission 34.2 (18.6) vs. 19.0 (11.3) for those aged ≥ 75 years.

Conclusions

Routine application of PROMs can provide valuable information relating to multiple aspects of clinical recovery for individuals hospitalized with CAP. However, heterogeneous demographic characteristics and complex underlying health status introduce challenges to feasibility and interpretability of these instruments in this population.

Out-of-pocket healthcare expenditure in Australia: trends, inequalities and the impact on household living standards in a high-income country with a universal health care system

BACKGROUND

Poor health increases the likelihood of experiencing poverty by reducing a person's ability to work and imparting costs associated with receiving medical treatment. Universal health care is a means of protecting against the impoverishing impact of high healthcare costs. This study aims to document the recent trends in the amount paid by Australian households out-of-pocket for healthcare, identify any inequalities in the distribution of this expenditure, and to describe the impact that healthcare costs have on household living standards in a high-income country with a long established universal health care system. We undertook this analysis using a longitudinal, nationally representative dataset - the Household Income and Labour Dynamics in Australia Survey, using data collected annually from 2006 to 2014. Out of pocket payments covered those paid to health practitioners, for medication and in private health insurance premiums; catastrophic expenditure was defined as spending 10% or more of household income on healthcare.

RESULTS

Average total household expenditure on healthcare items remained relatively stable between 2006 and 2014 after adjusting for inflation, changing from $3133 to $3199. However, after adjusting for age, self-reported health status, and year, those in the lowest income group (decile one) had 15 times the odds (95% CI, 11.7-20.8) of having catastrophic health expenditure compared to those in the highest income group (decile ten). The percentage of people in income decile 2 and 3 who had catastrophic health expenditure also increased from 13% to 19% and 7% to 13% respectively.

CONCLUSIONS

Ongoing monitoring of out of pocket healthcare expenditure is an essential part of assessing health system performance, even in countries with universal health care.

Non-urgent paediatric emergency department presentation: A systematic review

There has been an increase in the use of the emergency department (ED) for non-urgent presentations. The aim of this systematic review was to identify the proportion, criteria and predictors of non-urgent ED presentations in paediatric populations. A search of multiple databases was conducted for articles published from inception of the databases to 20 August 2018, which reported the proportion, criteria and predictors of non-urgent ED presentation in paediatric populations. Thirty-one articles met the inclusion criteria. The mean proportion of non-urgent paediatric ED presentations was 41.06 ± 15.16%. There appears to be a weak association between predisposing, enabling and needs factors and non-urgent ED use in paediatric populations. The findings of this review suggest that non-urgent ED use in paediatric populations is high. However, non-urgent ED use and the reasons for the visits in paediatric populations remain understudied.

The Effect of Childhood ADD/ADHD on Parental Workforce Participation

OBJECTIVE

This research aimed to examine the impact of attention deficit disorder (ADD)/ADHD in children on parental labor force participation across different child age groups.

METHOD

This study utilized a longitudinal, quantitative analyses approach. All data were collected from Wave 6 of the Growing Up in Australia: The Longitudinal Study of Australian Children (LSAC) survey.

RESULTS

After adjusting for various confounders, mothers whose children were 10/11 years old and had been diagnosed with ADD/ADHD were significantly more likely to be out of the labor force compared with those mothers whose child had not been diagnosed with ADD/ADHD. The impact was more pronounced for single mothers. No significant influence on paternal labor force participation was found.

CONCLUSION

In assessing the cost-effectiveness of interventions for ADD/ADHD, policy makers and researchers must consider the long-term social and economic effects of ADD/ADHD on maternal workforce participation when considering costs and outcomes.

Who experiences unmet need for mental health services and what other barriers to accessing health care do they face? Findings from Australia and Canada

PURPOSE

To examine factors associated with unmet need for mental health services and links with barriers to access to care more broadly.

METHODOLOGY

The Commonwealth Fund International Health Policy Surveys from 2013 and 2016 were used to explore factors associated with unmet need for adults who experienced emotional distress for 1320 respondents in Australia and 2284 in Canada.

FINDINGS

Over one in five adults in Australia (21%) and in Canada (25%) experienced emotional distress, just over half said they received professional help (51% in Australia, 59% in Canada). The majority of those who did not get help indicated did not want to see a professional (37% in Australia, 30% in Canada). For those who did seek help, the factors associated with not receiving care included lower income, higher out-of-pocket health care costs, and poorer health. When compared with people with met needs, those with unmet needs for mental health services were more likely to also experience affordability, medication, and trust-related access barriers (AOR range 2.41 to 7.49 for the two countries, P < 0.01).

CONCLUSION

Including unmet needs for mental health services as part of regular reporting on access to care may bring attention to access barriers for people with mental health conditions.

Cost-effectiveness of continuity of midwifery care for women with complex pregnancy: a structured review of the literature

BACKGROUND

Critical evaluation of the cost-effectiveness and clinical effectiveness of continuity of midwifery care models for women experiencing complex pregnancy is an important consideration in the review and reform of maternity services. Most studies either focus on women who experience healthy pregnancy or mixed risk samples. These results may not be generalised across the childbearing continuum to women with risk factors. This review critically evaluates studies that measure the cost of care for women with complex pregnancies, with a focus on method and quality.

AIMS / OBJECTIVES

To critically appraise and summarise the evidence relating to the combined cost-effectiveness, resource use and clinical effectiveness of midwifery continuity models for women who experience complex pregnancies and their babies in developed countries.

DESIGN

Structured review of the literature utilising a matrix method to critique the methods and quality of studies.

METHOD

A search of Medline, CINAHL, MIDIRS, DARE, EMBASE, OVID, PubMed, ProQuest, Informit, Science Direct, Cochrane Library, NHS Economic Evaluation Database (NHSEED) for the years 1994 - 2018 was conducted.

RESULTS

Nine articles met the inclusion criteria. The review identified four areas of economic evaluation that related to women who experienced complex pregnancy and continuity of midwifery care. (1) cost and clinical effectiveness comparisons between continuity of midwifery care versus obstetric-led units; (2) cost of continuity of midwifery care and/or team midwifery compared to Standard Care; (3) cost-effectiveness of continuity of midwifery care for Australian Aboriginal women versus standard care; (4) patterns of antenatal care for women of high obstetric risk and comparative provider cost. Cost savings specific to women from high risk samples who received continuity of midwifery care compared with obstetric-led standard care was stated for only one study in the review. Kenny et al. 1994 identified cost savings of AUS $29 in the antenatal period for women who received the midwifery team model from a stratified sub-set of high-risk pregnant woman within a mixed risk sample of 446 women. One systematic review relevant to the UK context, Ryan et al. (2013), applied sensitivity analysis to include women of all risk categories. Where risk ratio for overall fetal/neonatal death was systematically varied based on the 95% confidence interval of 0.79 to 1.09 from pooled studies, the aggregate annual net monetary benefit for continuity of midwifery care ranged extremely widely from an estimated gain of £472 million to a loss of £202 million. Net health benefit ranged from an annual gain of 15 723 QALYs to a loss of 6 738 QALYs. All other studies in this review reported cost savings narratively or within mixed risk samples where risk stratification was not clearly stated or related to the midwifery team model only.

CONCLUSIONS

Studies that measure the cost of continuity of midwifery care for women with complex pregnancy across the childbearing continuum are limited and apply inconsistent methods of economic evaluation. The cost and outcomes of implementing continuity of midwifery care for women with complex pregnancy is an important issue that requires further investigation. Robust cost-effectiveness evidence is essential to inform decision makers, to implement sustainable systems change in comparative maternity models for pregnant women at risk and to address health inequity.

Socio-economic composition of low-acuity paediatric presentation at a regional hospital emergency department

AIM

Despite increasing rates of emergency department (ED) utilisation, little is known about low-acuity presentations in children ≤5 years. The aims of the study were to estimate the proportion and cost of low-acuity presentations in children ≤5 years presenting to the ED and to determine the relative effect of socio-economic status (SES) on paediatric low-acuity presentations at the ED.

METHODS

This is a retrospective observational study of children ≤5 years presenting to the Cairns Hospital ED over 4 years. A multivariate logistic regression model was used to assess the association between SES and low-acuity presentations. Cost of low-acuity presentations was calculated based on triage score and admission status, using costs obtained from the National Hospital Cost Data Collection.

RESULTS

A total of 23 086 children were included in the study, of whom 56.7% were male (mean age = 1.85 ± 1.63 years). Approximately one-third of ED visits were low-acuity presentations (32.4%), and low-acuity presentations increased progressively with SES. In multivariate analysis, children from families with very high SES were twice as likely to have a low-acuity presentation (odds ratio 2.17; 95% confidence interval, 1.66-2.85). Low-acuity ED presentations cost the health-care system in excess of A$895 000-A$1 110 000 per year.

CONCLUSIONS

These findings demonstrate that a significant proportion of paediatric ED visits are of low acuity and that these visits yield a substantial cost to the health system. Further research is required regarding care givers' rationale and potentially other reasons underlying these low-acuity ED presentations.

Does screening for congenital cytomegalovirus at birth improve longer term hearing outcomes?

Currently, the diagnosis of congenital cytomegalovirus (cCMV) infection in most highly resourced countries is based on clinical suspicion alone. This means only a small proportion of cCMV infections are diagnosed. Identification, through either universal or targeted screening of asymptomatic newborns with cCMV, who would previously have gone undiagnosed, would allow for potential early treatment with antiviral therapy, ongoing audiological surveillance and early intervention if sensorineural hearing loss (SNHL) is identified. This paper systematically reviews published papers examining the potential benefits of targeted and universal screening for newborn infants with cCMV. We found that the treatment of these infants with antiviral therapy remains controversial, and clinical trials are currently underway to provide further answers. The potential benefit of earlier identification and intervention (eg, amplification and speech therapy) of children at risk of later-onset SNHL identified through universal screening is, however, clearer.

Considerations for the Development of Mobile Phone Apps to Support Diabetes Self-Management: Systematic Review

Background

There is increased research interest in the use of mobile phone apps to support diabetes management. However, there are divergent views on what constitute the minimum standards for inclusion in the development of mobile phone apps. Mobile phone apps require an evidence-based approach to development which will consequently impact on their effectiveness. Therefore, comprehensive information on developmental considerations could help designers and researchers to develop innovative and effective patient-centered self-management mobile phone apps for diabetes patients.

Objective

This systematic review examined the developmental considerations adopted in trials that engaged mobile phone applications for diabetes self-management.

Methods

A comprehensive search strategy was implemented across 5 electronic databases; Medline, Scopus, Social Science Citation Index, the Cochrane Central Register of Controlled Trials and Cumulative Index of Nursing and Allied Health Literature (CINALHL) and supplemented by reference list from identified studies. Study quality was evaluated using the Joanna Briggs Critical appraisal checklist for trials. Information on developmental factors (health behavioral theory, functionality, pilot testing, user and clinical expert involvements, data privacy and app security) were assessed across experimental studies using a template developed for the review.

Results

A total of 11 studies (10 randomized controlled trials and 1 quasi-experimental trial) that fitted the inclusion criteria were identified. All the included studies had the functionality of self-monitoring of blood glucose. However, only some of them included functions for data analytics (7/11, 63.6%), education (6/11, 54.5%) and reminder (6/11, 54.5%). There were 5/11(45.5%) studies with significantly improved glycosylated hemoglobin in the intervention groups where educational functionality was present in the apps used in the 5 trials. Only 1 (1/11, 9.1%) study considered health behavioral theory and user involvement, while 2 (2/11, 18.1%) other studies reported the involvement of clinical experts in the development of their apps. There were 4 (4/11, 36.4%) studies which referred to data security and privacy considerations during their app development while 7 (7/12, 63.6%) studies provided information on pilot testing of apps before use in the full trial. Overall, none of the studies provided information on all developmental factors assessed in the review.

Conclusions

There is a lack of elaborate and detailed information in the literature regarding the factors considered in the development of apps used as interventions for diabetes self-management. Documentation and inclusion of such vital information will foster a transparent and shared decision-making process that will ultimately lead to the development of practical and user-friendly self-management apps that can enhance the quality of life for diabetes patients.

International comparisons of disparities in access to care for people with mental health conditions

OBJECTIVE

Relatively little is known about experiences of barriers in access to overall care for people with mental health conditions (MHCs), or disparities between people with and without MHCs, or how patterns vary across countries.

DATA AND METHOD

The 2016 Commonwealth Fund International Health Policy Survey of adults was used to compare access barriers for people with MHCs across 11 countries, and disparities within countries between people with and without an MHC, using normalized scores. Disparities were also assessed by using multivariable models adjusting for age, sex, immigrant status, income, and self-rated health.

RESULT

On average, people with MHCs had a higher prevalence of barriers, with a gap of 7 percentage points between people with and without MHCs. The gap ranged from 5 to 9% across countries. For people with an MHC, the most common access barriers were skipping care due to cost (26%) and receiving conflicting information from providers (26%). For all countries, having an MHC was associated with higher odds of experiencing barriers of access to care on several measures, with at least 1 case where the adjusted odds were greater than 2.

CONCLUSION

There is an imperative to improve monitoring of access to overall health care for people with MHCs and an opportunity learn from countries with fewer barriers and disparities in access to care.

Psychological distress increases the risk of falling into poverty amongst older Australians: the overlooked costs-of-illness

Background

This paper aimed to identify whether high psychological distress is associated with an increased risk of income and multidimensional poverty amongst older adults in Australia.

Methods

We undertook longitudinal analysis of the nationally representative Household Income and Labour Dynamics in Australian (HILDA) survey using modified Poisson regression models to estimate the relative risk of falling into income poverty and multidimensional poverty between 2010 and 2012 for males and females, adjusting for age, employment status, place of residence, marital status and housing tenure; and Population Attributable Risk methodology to estimate the proportion of poverty directly attributable to psychological distress, measured by the Kessler 10 scale.

Results

For males, having high psychological distress increased the risk of falling into income poverty by 1.68 (95% CI: 1.02 to 2.75) and the risk of falling into multidimensional poverty by 3.40 (95% CI: 1.91 to 6.04). For females, there was no significant difference in the risk of falling into income poverty between those with high and low psychological distress (p = 0.1008), however having high psychological distress increased the risk of falling into multidimensional poverty by 2.15 (95% CI: 1.30 to 3.55). Between 2009 and 2012, 8.0% of income poverty cases for people aged 65 and over (95% CI: 7.8% to 8.4%), and 19.5% of multidimensional poverty cases for people aged 65 and over (95% CI: 19.2% to 19.9%) can be attributed to high psychological distress.

Conclusions

The elevated risk of falling into income and multidimensional poverty has been an overlooked cost of poor mental health.

What are the costs associated with child and maternal healthcare within Australia? A study protocol for the use of data linkage to identify health service use, and health system and patient costs

INTRODUCTION

The current literature in Australia demonstrates that there are variations in access and outcomes in perinatal care based on socioeconomic factors. However, little has been done looking at the level of out-of-pocket healthcare costs associated with perinatal care. The primary aim of this project will be to quantify health service use and out-of-pocket healthcare expenditure associated with childbearing and early childhood in Queensland, Australia.

METHODS AND ANALYSIS

This project will build Australia's first model (called Maternal & Child Cost MOD) of out-of-pocket healthcare expenditure by using administrative data from the Queensland Perinatal Data Collection, of all childbearing women and their resultant children, who gave birth in Queensland between 1 July 2012 and 30 June 2016.The current costs to the health system and out-of-pocket health care expenditure of patients associated with maternity and early childhood health care will be identified. The differences in costs based on indigenous identification, socioeconomic status and geographic location will be assessed using linear regression modelling and counterfactual modelling techniques.
