Social determinants and exposure to intimate partner violence in women with severe acute maternal morbidity in the intensive care unit: a systematic review.

BACKGROUND: Studying severe acute maternal morbidity in the intensive care unit improves our understanding of potential factors affecting maternal health. AIM: To review evidence on maternal exposure to intimate partner violence and social determinants of health in women with severe acute maternal morbidity in the intensive care unit. METHODS: The protocol for this review was registered in PROSPERO (registration number CRD42016037492). A systematic search was performed in MEDLINE, CINAHL, ProQuest, LILACS and SciELO using the search terms "intensive care unit", "intensive care", "critical care" and "critically ill" in combination with "intimate partner violence", "social determinants of health", "severe acute maternal morbidity", pregnancy, postpartum and other similar terms. Eligible studies were (i) quantitative, (ii) published in English and Spanish, (iii) from 2000 to 2021, (iv) with data related to intimate partner violence and/or social determinants of health, and (v) investigating severe acute maternal morbidity (maternity patients treated in the intensive care unit during pregnancy, childbirth or within 42 days of pregnancy termination). Of 52,866 studies initially identified, 1087 full texts were assessed and 156 studies included. Studies were independently assessed by two reviewers for screening, revision, quality assessment and abstracted data. Studies were categorised into high/middle/low-income countries and summarised data were presented using a narrative description, due to heterogenic data as: (i) exposure to intimate partner violence and (ii) social determinants of health. RESULTS: One study assessed intimate partner violence among mothers with severe acute maternal morbidity in the intensive care unit and found that women exposed to intimate partner violence before and during pregnancy had a nearly four-fold risk of severe acute maternal morbidity requiring ICU admission. Few social determinants of health other than age were reported in most studies. CONCLUSION: This review identified a significant gap in knowledge concerning intimate partner violence and social determinants of health in women with severe acute maternal morbidity in the intensive care unit, which is essential to better understand the complete picture of the maternal morbidity spectrum and reduce maternal mortality.

The impact of the COVID-19 pandemic on critical care healthcare professionals' work practices and wellbeing: A qualitative study.

BACKGROUND: Burnout and other psychological comorbidities were evident prior to the COVID-19 pandemic for critical care healthcare professionals (HCPs) who have been at the forefront of the health response. Current research suggests an escalation or worsening of these impacts as a result of the COVID-19 pandemic. OBJECTIVES: The objective of this study was to undertake an in-depth exploration of the impact of the evolving COVID-19 pandemic on the wellbeing of HCPs working in critical care. METHODS: This was a qualitative study using online focus groups (n = 5) with critical care HCPs (n = 31, 7 medical doctors and 24 nurses) in 2021: one with United Kingdom-based participants (n = 11) and four with Australia-based participants (n = 20). Thematic analysis of qualitative data from focus groups was performed using Gibbs framework. FINDINGS: Five themes were synthesised: transformation of anxiety and fear throughout the pandemic, the burden of responsibility, moral distress, COVID-19 intruding into all aspects of life, and strategies and factors that sustained wellbeing during the pandemic. Moral distress was a dominant feature, and intrusiveness of the pandemic into all aspects of life was a novel finding. CONCLUSIONS: The COVID-19 pandemic has adversely impacted critical care HCPs and their work experience and wellbeing. The intrusiveness of the pandemic into all aspects of life was a novel finding. Moral distress was a predominate feature of their experience. Leaders of healthcare organisations should ensure that interventions to improve and maintain the wellbeing of HCPs are implemented.

Nursing workforce deployment and intensive care unit strain during the COVID-19 pandemic in Victoria, Australia.

BACKGROUND: The COVID-19 pandemic demanded intensive care units (ICUs) globally to expand to meet increasing patient numbers requiring critical care. Critical care nurses were a finite resource in this challenge to meet growing patient numbers, necessitating redeployment of nursing staff to work in ICUs. OBJECTIVE: Our aim was to describe the extent and manner by which the increased demand for ICU care during the COVID-19 pandemic was met by ICU nursing workforce expansion in the late 2021 and early 2022 in Victoria, Australia. METHODS: This is a retrospective cohort study of Victorian ICUs who contributed nursing data to the Critical Health Information System from 1 December 2021 to 11 April 2022. Bedside nursing workforce data, in categories as defined by Safer Care Victoria's pandemic response guidelines, were analysed. The primary outcome was 'insufficient ICU skill mix'-whenever a site had more patients needing 1:1 critical care nursing care than the mean daily number of experienced critical care nursing staff. RESULTS: Overall, data from 24 of the 47 Victorian ICUs were eligible for analysis. Insufficient ICU skill mix occurred on 10.3% (280/2725) days at 66.7% (16/24) of ICUs, most commonly during the peak phase from December to mid-February. The insufficient ICU skill mix was more likely to occur when there were more additional ICU beds open over the 'business-as-usual' number. Counterfactual analysis suggested that had there been no redeployment of staff to the ICU, reduced nursing ratios, with inability to provide 1:1 care, would have occurred on 15.2% (415/2725) days at 91.7% (22/24) ICUs. CONCLUSION: The redeployment of nurses into the ICU was necessary. However, despite this, at times, some ICUs had insufficient staff to cope with the number and acuity of patients. Further research is needed to examine the impact of ICU nursing models of care on patient outcomes and on nurse outcomes.

Organizational strategies to optimize women's safety during labor and birth: A scoping review.

BACKGROUND: Safety is a priority for organizations that provide maternity care, however, preventable harm and errors in maternity care remain. Maternity care is considered a high risk and high litigation area of health care. To mitigate risk and litigation, organizations have implemented strategies to optimize women's safety. Our objectives were to identify the strategies implemented by organizations to optimize women's safety during labor and birth, and to consider how the concept of safety is operationalized to measure and evaluate outcomes of these strategies. METHOD: This scoping review was conducted using the Joanna Briggs Institute Scoping Review Methodology. Published peer-reviewed literature indexed in CINAHL, Medline, and Embase, databases from 2010 to 2020, were reviewed for inclusion. Fifty studies were included. Data were extracted and thematically analyzed. RESULTS: Three categories of organizational strategies were identified to optimize women's safety during labor and birth: clinical governance, models of care, and staff education. Clinical governance programs (n = 30 studies), specifically implementing checklists and audits, models of care, such as midwifery led-care (n = 11 studies), and staff training programs (n = 9 studies), were predominately for the management of obstetric emergencies. Outcome measures included morbidity and mortality for woman and newborns. Three studies discussed women's perceptions of safety during labor and birth as an outcome measure. CONCLUSIONS: Organizations utilize a range of strategies to optimize women's safety during labor and birth. The main outcome measure used to evaluate strategies was focused on clinical outcomes for the mother and newborn.

A critical care pandemic staffing framework in Australia.

BACKGROUND: Pandemics and the large-scale outbreak of infectious disease can significantly impact morbidity and mortality worldwide. The impact on intensive care resources can be significant and often require modification of service delivery, a key element which includes rapid expansion of the critical care workforce. Pandemics are also unpredictable, which necessitates rapid decision-making and action which, in the lack of experience and guidance, may be extremely challenging. Recognising the potential strain on intensive care units (ICUs), particularly on staffing, a working group was formed for the purpose of developing recommendations to support decision-making during rapid service expansion. METHODS: The Critical Care Pandemic Staffing Working Party (n = 21), representing nursing, allied health, and medical disciplines, has used a modified consensus approach to provide recommendations to inform multidisciplinary workforce capacity expansion planning in critical care. RESULTS: A total of 60 recommendations have been proposed which reflect general recommendations as well as those specific to maintaining the critical care workforce, expanding the critical care workforce, rostering and allocation of the critical care workforce, nurse-specific recommendations for staffing the ICU, education support and training during ICU surge situations, workforce support, models of care, and de-escalation. CONCLUSION: These recommendations are provided with the intent that they be used to guide interdisciplinary decision-making, and we suggest that careful consideration is given to the local context to determine which recommendations are most appropriate to implement and how they are prioritised. Ongoing evaluation of recommendation implementation and impact will be necessary, particularly in rapidly changing clinical contexts.

Haematological features, transfusion management and outcomes of massive obstetric haemorrhage: findings from the Australian and New Zealand Massive Transfusion Registry.

Massive obstetric haemorrhage (MOH) is a leading cause of maternal morbidity and mortality world-wide. Using the Australian and New Zealand Massive Transfusion Registry, we performed a bi-national cohort study of MOH defined as bleeding at ≥20 weeks' gestation or postpartum requiring ≥5 red blood cells (RBC) units within 4 h. Between 2008 and 2015, we identified 249 cases of MOH cases from 19 sites. Predominant causes of MOH were uterine atony (22%), placenta praevia (20%) and obstetric trauma (19%). Intensive care unit admission and/or hysterectomy occurred in 44% and 29% of cases, respectively. There were three deaths. Hypofibrinogenaemia (<2 g/l) occurred in 52% of cases in the first 24 h after massive transfusion commenced; of these cases, 74% received cryoprecipitate. Median values of other haemostatic tests were within accepted limits. Plasma, platelets or cryoprecipitate were transfused in 88%, 66% and 57% of cases, respectively. By multivariate regression, transfusion of ≥6 RBC units before the first cryoprecipitate (odds ratio [OR] 3·5, 95% CI: 1·7-7·2), placenta praevia (OR 7·2, 95% CI: 2·0-26·4) and emergency caesarean section (OR 4·9, 95% CI: 2·0-11·7) were independently associated with increased risk of hysterectomy. These findings confirm MOH as a major cause of maternal morbidity and mortality and indicate areas for practice improvement.

Intimate partner violence and severe acute maternal morbidity in the intensive care unit: A case-control study in Peru.

BACKGROUND: Intimate partner violence is a prevalent public health issue associated with all-cause maternal mortality. This study investigated the relationship between intimate partner violence, severe acute maternal morbidity in the intensive care unit (ICU), and neonatal outcomes. METHODS: This was a prospective case-control study in a hospital in Lima, Peru, with 109 cases (maternal ICU admissions) and 109 controls (obstetric patients not admitted to the ICU). Data were collected through face-to-face interviews and medical record review. Partner violence was assessed using the World Health Organization instrument. Multivariate logistic regression was used to model the association between intimate partner violence and severe acute maternal morbidity. RESULTS: There was a significantly higher rate of intimate partner violence both before and during pregnancy among cases (58.7%) than controls (27.5%). In multivariate analysis, intimate partner violence both before and during pregnancy (aOR 3.83 (95% CI: 1.99-7.37)), being married (3.86 (1.27-11.73)), having <8 antenatal care visits (2.78 (1.14-6.80)), and having previous abortions (miscarriage, therapeutic, or unsafe) (1.69 (1.13-2.51)) were significantly associated with severe acute maternal morbidity. The ICU admission rate was 18.8 (per 1000 live births), and ICU maternal mortality was 1.7%. The perinatal mortality rate was higher in cases (9.3%) than in controls (1.8%). CONCLUSIONS: Intimate partner violence was associated with an increased risk of severe acute maternal morbidity. This suggests a more severe impact of intimate partner violence on pregnancy than has been previously identified. Inquiring about intimate partner violence during prenatal visits may prevent further harm to the mother-baby dyad.

Risk factors for severe postpartum haemorrhage: A population-based retrospective cohort study.

BACKGROUND: Severe postpartum haemorrhage (PPH) is a serious clinical problem that is increasing in incidence. AIM: To identify risk factors for severe PPH. MATERIALS AND METHODS: Population-based retrospective cohort study of all women who gave birth in Victoria in 2009-2013 using the validated Victorian Perinatal Data Collection. Three multivariable logistic regression models estimated the adjusted risk of severe PPH. Adjusted odds ratios (aOR) and their 95% confidence intervals are reported. The primary outcome was severe PPH (estimated blood loss of ≥1500 mL). RESULTS: Severe PPH occurred in 1.4% of all births (n = 5122). Maternal characteristics significantly associated with severe PPH included: multiple pregnancy; older maternal age; overweight/obesity; first births. Other risk factors included placental complications, macrosomia, instrumental vaginal birth, third and fourth degree perineal lacerations, in-labour caesarean section, birth at a gestation other than 37-41 weeks, duration of labour 12 to <24 h, and use of oxytocin infusions in labour. Planned pre-labour caesarean section was associated with reduced odds of severe PPH. Severe PPH also occurred in 0.7% (n = 104) of women with none of the identified risk factors. CONCLUSIONS: Numerous risk factors for severe PPH are identified but some cases are not modifiable or predictable. Limiting use of oxytocin infusions in labour to cases with clear indications, and strategies to prevent severe perineal lacerations would prevent some severe PPHs. Close surveillance of all women in the hours immediately following birth is crucial to detect and manage excessive blood loss and reduce severe PPH and associated morbidity.

Eclampsia in Australia and New Zealand: A prospective population-based study.

BACKGROUND: Eclampsia is a serious consequence of pre-eclampsia. There are limited data from Australia and New Zealand (ANZ) on eclampsia. AIM: To determine the incidence, management and perinatal outcomes of women with eclampsia in ANZ. MATERIALS AND METHODS: A two-year population-based descriptive study, using the Australasian Maternity Outcomes Surveillance System (AMOSS), carried out in 263 sites in Australia, and all 24 New Zealand maternity units, during a staggered implementation over 2010-2011. Eclampsia was defined as one or more seizures during pregnancy or postpartum (up to 14 days) in any woman with clinical evidence of pre-eclampsia. RESULTS: Of 136 women with eclampsia, 111 (83%) were in Australia and 25 (17%) in New Zealand. The estimated incidence of eclampsia was 2.2 (95% confidence interval (CI) 1.9-2.7) per 10 000 women giving birth. Aboriginal and Torres Strait Islander women were over-represented in Australia (n = 9; 8.1%). Women with antepartum eclampsia (n = 58, 42.6%) were more likely to have a preterm birth (P = 0.04). Sixty-three (47.4%) women had pre-eclampsia diagnosed prior to their first eclamptic seizure of whom 19 (30.2%) received magnesium sulphate prior to the first seizure. Nearly all women (n = 128; 95.5%) received magnesium sulphate post-seizure. No woman received prophylactic aspirin during pregnancy. Five women had a cerebrovascular haemorrhage, and there were five known perinatal deaths. CONCLUSIONS: Eclampsia is an uncommon consequence of pre-eclampsia in ANZ. There is scope to reduce the incidence of this condition, associated with often catastrophic morbidity, through the use of low-dose aspirin and magnesium sulphate in women at higher risk.

A Comparison of Moderate to Late Preterm Neonates Receiving Nasal Continuous Positive Airway Pressure in Australian Tertiary and Nontertiary Centers.

PURPOSE: Transfer of neonates ≥32 weeks' gestation with acute respiratory distress to tertiary (T) centers can be reduced by treatment with nasal continuous positive airway pressure (nCPAP) in nontertiary (NT) centers. This can lead to considerable financial and emotional benefits. The aim of this project was to compare management of nCPAP in T and NT centers. DESIGN: Five-year retrospective, observational cohort study (2010-2014). SAMPLE: All NT eligible neonates from four sites (n = 484) were compared with a similar randomized cohort of inborn neonates at two T centers (n = 601) in Victoria, Australia. MAIN OUTCOME VARIABLE: Any difference in management or short-term outcome. RESULTS: Moderately preterm and term neonates born in NT centers had lower Apgar scores at five minutes of age and received more conservative management delivered by different equipment. Despite a higher incidence of air leaks in NT centers, the short-term outcomes were otherwise similar between centers. T centers were more likely to administer nCPAP to term babies for <24 hours.

Incidence, trends and severity of primary postpartum haemorrhage in Australia: A population-based study using Victorian Perinatal Data Collection data for 764 244 births.

BACKGROUND: Increasing incidence and severity of postpartum haemorrhage, together with postpartum haemorrhage-associated morbidities, have been reported in many high-resource countries. In-depth analysis of such factors in Victorian births since 2002 was lacking. AIMS: Our aim was to determine the incidence and trends for primary postpartum haemorrhage (World Health Organization and International Classification of Diseases 10th revision, Australian Modification definitions) for all confinements in Victoria, Australia, for the years 2003-2013 and the incidence and trends for severe postpartum haemorrhage (≥1500 mL) for 2009-2013. MATERIALS AND METHODS: In this population-based cross-sectional study de-identified data from the Victorian Perinatal Data Collection were analysed for confinements (excluding terminations) from 2003 to 2013 (n = 764 244). Perinatal information for all births ≥20 weeks (or of at least 400 g birthweight if gestation was unknown) were prospectively collected. RESULTS: One in five women (21.8%) who gave birth between 2009 and 2013 experienced a primary postpartum haemorrhage and one in 71 women (1.4%) experienced a severe primary postpartum haemorrhage. The increasing trends in incidence of primary postpartum haemorrhage, severe primary postpartum haemorrhage, blood transfusion, admission to an intensive care or high dependency unit and peripartum hysterectomy were significant (P < 0.001). Women who had an unassisted vaginal birth had the lowest incidence of primary postpartum haemorrhage. The highest incidence was experienced by women who had an unplanned caesarean section birth. Women who had a forceps birth had the highest incidence of severe primary postpartum haemorrhage. CONCLUSIONS: The incidence of primary postpartum haemorrhage, severe primary postpartum haemorrhage and associated maternal morbidities have increased significantly over time in Victoria.

Accuracy of postpartum haemorrhage data in the 2011 Victorian Perinatal Data Collection: Results of a validation study.

BACKGROUND: The postpartum haemorrhage (PPH) rate in Victoria in 2009 for women having their first birth, based on information reported to the Victorian Perinatal Data Collection (VPDC), was 23.6% (primiparas). Prior to 2009 PPH was collected via a tick box item on the perinatal form. Estimated blood loss (EBL) volume is now collected and it is from this item the PPH rate is calculated. Periodic assessment of data accuracy is essential to inform clinicians and others who rely on these data of their quality and limitations. AIMS: This paper describes the results of a state-wide validation study of the accuracy of EBL volume and EBL-related data items reported to VPDC. MATERIALS AND METHODS: PPH data from a random sample of 1% of births in Victoria in 2011 were extracted from source medical records and compared with information submitted to the VPDC. Accuracy was determined, together with sensitivity, specificity, positive predictive value and negative predictive value for dichotomous items. RESULTS: Accuracy of reporting for EBL ≥ 500 mL was 97.2% and for EBL ≥ 1500 mL was 99.7%. Sensitivity for EBL ≥ 500 mL was 89.0% (CI 83.1-93.0) and for EBL ≥ 1500 mL was 71.4% (CI 35.9-91.8). Blood product transfusion, peripartum hysterectomy and procedures to control bleeding were all accurately reported in >99% of cases. CONCLUSIONS: Most PPH-related data items in the 2011 VPDC may be considered reliable. Our results suggest EBL ≥ 1500 mL is likely to be under-reported. Changes to policies and practices of recording blood loss could further increase accuracy of reporting.

ACCCN Workforce Standards for Intensive Care Nursing: Systematic and evidence review, development, and appraisal.

BACKGROUND: The intensive care nursing workforce plays an essential role in the achievement of positive healthcare outcomes. A growing body of evidence indicates that inadequate nurse staffing and poor skill mix are associated with negative outcomes for patients, and potentially compromises nurses' ability to maintain the safety of those in their care. In Australia, the Australian College of Critical Care Nurses (ACCCN) has previously published a position statement on intensive care staffing. There was a need for a stronger more evidence based document to support the intensive nursing workforce. OBJECTIVES: To undertake a systematic and evidence review of the evidence related to intensive care nurse staffing and quality of care, and determine evidence-based professional standards for the intensive care nursing workforce in Australia. METHODS: The National Health and Medical Research Council standard for clinical practice guidelines methodology was employed. The English language literature, for the years 2000-2015 was searched. Draft standards were developed and then peer- and consumer-reviewed. RESULTS: A total of 553 articles was retrieved from the initial searches. Following evaluation, 231 articles met the inclusion criteria and were assessed for quality using established criteria. This evidence was used as the basis for the development of ten workforce standards, and to establish the overall level of evidence in support of each standard. All draft standards and their subsections were supported multi-professionally (median score >6) and by consumers (85-100% agreement). Following minor revisions, independent appraisal using the AGREE II tool indicated that the standards were developed with a high degree of rigour. CONCLUSION: The ACCCN intensive care nursing nurse workforce standards are the first to be developed using a robust, evidence-based process. The standards represent the optimal nurse workforce to achieve the best patient outcomes and to maintain a sustainable intensive care nursing workforce for Australia.

Vaginal pessaries: can an educational brochure help patients to better understand their care?

AIMS AND OBJECTIVES: Pelvic organ prolapse is a common condition, with reported incidence of up to 50%. We aimed to assess whether written information, in addition to face-to-face consultation, improved happiness with information, confidence to self-manage and prolapse knowledge in women attending a pessary clinic. BACKGROUND: Little is known about the effect of adding a written information brochure on clinical outcomes of patients using pessaries. DESIGN: This prospective study used a pretest-posttest method, conducted following Ethical approval. METHODS: Between February-December 2013, all women attending Pessary Clinic were eligible for participation. A questionnaire was developed to assess happiness with information, confidence regarding self-management (using a visual analogue scale, 1-10) and prolapse knowledge (using eight multiple-choice questions). Data were collected in person at baseline prior to distribution of a patient brochure and thereafter by telephone at one week and three months. Paired analysis was conducted using the McNemar test and related samples Wilcoxon signed-rank test for VAS items with p < 0.05 significant. RESULTS: Sixty women were recruited. Fifty-eight completed all questionnaires. Improvement in happiness with information, confidence regarding self-management and knowledge scores occurred at one week (p < 0.05) and were maintained at three months (p < 0.05). Changes were unrelated to age (p > 0.05), education level (p > 0.05), first language (p > 0.05) or previous clinic visits (p > 0.05). CONCLUSION: A written information brochure, in addition to face-to-face consultation, improves happiness with information, confidence to self-manage and knowledge about pessaries compared to verbal instruction alone and helps patients better understand their care. The written brochure was equally effective in women with low education and advanced age, and occurred regardless of the number of clinic visits.

Increasing uptake of influenza vaccine by pregnant women post H1N1 pandemic: a longitudinal study in Melbourne, Australia, 2010 to 2014.

BACKGROUND: A Melbourne (Australia) university affiliated, tertiary obstetric hospital provides lay and professional education about influenza vaccine in pregnancy annually each March, early in the local influenza season. Responding to a 2011 survey of new mothers' opinions, the hospital made influenza vaccine freely available in antenatal clinics from 2012. We wished to determine influenza vaccination uptake during pregnancy with these strategies 5 years after 2009 H1N1. METHODS: Face to face interviews based on US Center for Disease Control and Prevention Pregnancy Risk Assessment Monitoring System with new mothers in postnatal wards each July, 2010 to 2014. We calculated recalled influenza vaccine uptake each year and assessed trends with chi square tests, and logistic regression. RESULTS: We recorded 1086 interviews. Influenza vaccination during pregnancy increased by 6% per year (95% confidence interval 4 to 8%): from 29.6% in 2010 to 51.3% in 2014 (p < 0.001). Lack of discussion from maternity caregivers was a persistent reason for non-vaccination, recalled by 1 in 2 non-vaccinated women. Survey respondents preferred face to face consultations with doctors and midwives, internet and text messaging as information sources about influenza vaccination. Survey responses indicate messages about vaccine safety in pregnancy and infant benefits are increasingly being heeded. However, there was progressively lower awareness of maternal benefits of influenza vaccination, especially for women with risk factors for severe disease. CONCLUSIONS: We observed improving influenza vaccination during pregnancy. There is potential to integrate technology such as text message or internet with antenatal consultations to increase vaccination coverage further.

Amniotic fluid embolism: an Australian-New Zealand population-based study.

BACKGROUND: Amniotic fluid embolism (AFE) is a major cause of direct maternal mortality in Australia and New Zealand. There has been no national population study of AFE in either country. The aim of this study was to estimate the incidence of amniotic fluid embolism in Australia and New Zealand and to describe risk factors, management, and perinatal outcomes. METHODS: A population-based descriptive study using the Australasian Maternity Outcomes Surveillance System (AMOSS) carried out in 263 eligible sites (>50 births per year) covering an estimated 96% of women giving birth in Australia and all 24 New Zealand maternity units (100% of women giving birth in hospitals) between January 1 2010-December 31 2011. A case of AFE was defined either as a clinical diagnosis (acute hypotension or cardiac arrest, acute hypoxia and coagulopathy in the absence of any other potential explanation for the symptoms and signs observed) or as a post mortem diagnosis (presence of fetal squames/debris in the pulmonary circulation). RESULTS: Thirty-three cases of AFE were reported from an estimated cohort of 613,731women giving birth, with an estimated incidence of 5.4 cases per 100,000 women giving birth (95% CI 3.5 to 7.2 per 100,000). Two (6%) events occurred at home whilst 46% (n = 15) occurred in the birth suite and 46% (n = 15) in the operating theatre (location not reported in one case). Fourteen women (42%) underwent either an induction or augmentation of labour and 22 (67%) underwent a caesarean section. Eight women (24%) conceived using assisted reproduction technology. Thirteen (42%) women required cardiopulmonary resuscitation, 18% (n = 6) had a hysterectomy and 85% (n = 28) received a transfusion of blood or blood products. Twenty (61%) were admitted to an Intensive Care Unit (ICU), eight (24%) were admitted to a High Dependency Unit (HDU) and seven (21%) were transferred to another hospital for further management. Five woman died (case fatality rate 15%) giving an estimated maternal mortality rate due to AFE of 0.8 per 100,000 women giving birth (95% CI 0.1% to 1.5%). There were two deaths among 36 infants. CONCLUSIONS: A coordinated emergency response requiring resource intense multi-disciplinary input is required in the management of women with AFE. Although the case fatality rate is lower than in previously published studies, high rates of hysterectomy, resuscitation, and admission to higher care settings reflect the significant morbidity associated with AFE. Active, ongoing surveillance to document the risk factors and short and long-term outcomes of women and their babies following AFE may be helpful to guide best practice, management, counselling and service planning. A potential link between AFE and assisted reproductive technology warrants further investigation.

Maternal super-obesity and perinatal outcomes in Australia: a national population-based cohort study.

BACKGROUND: Super-obesity is associated with significantly elevated rates of obstetric complications, adverse perinatal outcomes and interventions. The purpose of this study was to determine the prevalence, risk factors, management and perinatal outcomes of super-obese women giving birth in Australia. METHODS: A national population-based cohort study. Super-obese pregnant women (body mass index (BMI) >50 kg/m(2) or weight >140 kg) who gave birth between January 1 and October 31, 2010 and a comparison cohort were identified using the Australasian Maternity Outcomes Surveillance System (AMOSS). Outcomes included maternal and perinatal morbidity and mortality. Prevalence estimates calculated with 95% confidence intervals (CIs). Adjusted odds ratios (ORs) were calculated using multivariable logistic regression. RESULTS: 370 super-obese women with a median BMI of 52.8 kg/m(2) (range 40.9-79.9 kg/m(2)) and prevalence of 2.1 per 1 000 women giving birth (95% CI: 1.96-2.40). Super-obese women were significantly more likely to be public patients (96.2%), smoke (23.8%) and be socio-economically disadvantaged (36.2%). Compared with other women, super-obese women had a significantly higher risk for obstetric (adjusted odds ratio (AOR) 2.42, 95% CI: 1.77-3.29) and medical (AOR: 2.89, 95% CI: 2.64-4.11) complications during pregnancy, birth by caesarean section (51.6%) and admission to special care (HDU/ICU) (6.2%). The 372 babies born to 365 super-obese women with outcomes known had significantly higher rates of birthweight ≥ 4500 g (AOR 19.94, 95 % CI: 6.81-58.36), hospital transfer (AOR 3.81, 95 % CI: 1.93-7.55) and admission to Neonatal Intensive Care Unit (NICU) (AOR 1.83, 95% CI: 1.27-2.65) compared to babies of the comparison group, but not prematurity (10.5% versus 9.2%) or perinatal mortality (11.0 (95% CI: 4.3-28.0) versus 6.6 (95% CI: 2.6- 16.8) per 1 000 singleton births). CONCLUSIONS: Super-obesity in pregnancy in Australia is associated with increased rates of pregnancy and birth complications, and with social disadvantage. There is an urgent need to further address risk factors leading to super-obesity among pregnant women and for maternity services to better address pre-pregnancy and pregnancy care to reduce associated inequalities in perinatal outcomes.

The impact of nursing workforce skill-mix on patient outcomes in intensive care units in Victoria, Australia.

Objective: This article aims to examine the impact of nursing workforce skill-mix (percentage of critical care registered nurses [CCRN]) in the intensive care unit (ICU) during a patient's stay. Design: Registry linked cohort study of the Australian and New Zealand Intensive Care Society Adult Patient Database and the Critical Health Resources Information System using real-time nursing workforce data. Settings: Fifteen public and 5 private hospital ICUs in Victoria, Australia. Participants: There were 16,618 adult patients admitted between 1 December 2021 and 30 September 2022. Main outcome measures: Primary outcome: in-hospital mortality. Secondary outcomes: in-ICU mortality, development of delirium, pressure injury, duration of stay in-ICU and hospital, after-hours discharge from ICU and readmission to ICU. Results: In total, 6563 (39.5%) patients were cared for in ICUs with >75% CCRN, 7695 (46.3%) in ICUs with 50-75% CCRN, and 2360 (14.2%) in ICUs with <50% CCRN. In-hospital mortality was 534 (8.1%) vs. 859 (11.2%) vs. 252 (10.7%) respectively. After adjusting for confounders, patients cared for in ICUs with 50-75% CCRN (adjusted OR 1.21 [95% CI 1.02-1.45]) were more likely to die compared to patients in ICUs with >75% CCRN. A similar but non-significant trend was seen in ICUs with <50% CCRN (adjusted OR 1.21 [95% CI 0.94-1.55]), when compared to patients in ICUs with >75% CCRN. In-ICU mortality, delirium, pressure injuries, after-hours discharge and ICU length of stay were lower in ICUs with CCRN>75%. Conclusion: The nursing skill-mix in ICU impacts outcomes and should be routinely monitored. Health system regulators, hospital administrators and ICU leaders should ensure nursing workforce planning and education align with these findings to maximise patient outcomes.

A novel serogenetic approach determines the community prevalence of celiac disease and informs improved diagnostic pathways.

BACKGROUND: Changing perspectives on the natural history of celiac disease (CD), new serology and genetic tests, and amended histological criteria for diagnosis cast doubt on past prevalence estimates for CD. We set out to establish a more accurate prevalence estimate for CD using a novel serogenetic approach. METHODS: The human leukocyte antigen (HLA)-DQ genotype was determined in 356 patients with 'biopsy-confirmed' CD, and in two age-stratified, randomly selected community cohorts of 1,390 women and 1,158 men. Sera were screened for CD-specific serology. RESULTS: Only five 'biopsy-confirmed' patients with CD did not possess the susceptibility alleles HLA-DQ2.5, DQ8, or DQ2.2, and four of these were misdiagnoses. HLA-DQ2.5, DQ8, or DQ2.2 was present in 56% of all women and men in the community cohorts. Transglutaminase (TG)-2 IgA and composite TG2/deamidated gliadin peptide (DGP) IgA/IgG were abnormal in 4.6% and 5.6%, respectively, of the community women and 6.9% and 6.9%, respectively, of the community men, but in the screen-positive group, only 71% and 75%, respectively, of women and 65% and 63%, respectively, of men possessed HLA-DQ2.5, DQ8, or DQ2.2. Medical review was possible for 41% of seropositive women and 50% of seropositive men, and led to biopsy-confirmed CD in 10 women (0.7%) and 6 men (0.5%), but based on relative risk for HLA-DQ2.5, DQ8, or DQ2.2 in all TG2 IgA or TG2/DGP IgA/IgG screen-positive subjects, CD affected 1.3% or 1.9%, respectively, of females and 1.3% or 1.2%, respectively, of men. Serogenetic data from these community cohorts indicated that testing screen positives for HLA-DQ, or carrying out HLA-DQ and further serology, could have reduced unnecessary gastroscopies due to false-positive serology by at least 40% and by over 70%, respectively. CONCLUSIONS: Screening with TG2 IgA serology and requiring biopsy confirmation caused the community prevalence of CD to be substantially underestimated. Testing for HLA-DQ genes and confirmatory serology could reduce the numbers of unnecessary gastroscopies.

Triage of pregnant women in the emergency department: evaluation of a triage decision aid.

BACKGROUND: Applying the Australasian Triage Scale to pregnant women presenting to emergency departments (EDs) is difficult as the descriptors may not reflect the urgency of the obstetric condition. This study aimed to examine whether condition-specific algorithms and triage education improved triage assessment and documentation of pregnant women presenting to the ED. METHOD: Algorithms with a decision aid for triage with minimum agreed descriptors were developed to triage two pregnancy conditions (pre-eclampsia and antepartum haemorrhage). Triage documentation was then audited before (n=50) and after (n=50) a triage education programme which introduced algorithms for both conditions. Significant differences were examined using χ(2) test with significance set at p<0.05. RESULTS: The quality of documentation of specific clinically significant symptoms of pre-eclampsia improved considerably, including the presence of headache from 58% pre-education to 80% post-education (p=0.002), visual disturbances from 58% to 90% (p<0.001), epigastric pain from 24% to 80% (p=0.002) and the presence of fetal movements from 62% to 90% (p=0.001). Documentation of descriptors for vaginal bleeding >20 weeks gestation improved for estimation of blood loss from 54% to 86% (p<0.001), patient 'appearance' from 32% to 62% (p=0.003) and, importantly, descriptions of patient's own assessment of their well-being from 8% to 28% (p=0.009). CONCLUSION: The introduction of triage education and condition-specific decision aids for triage markedly improved triage assessment and documentation. The application of algorithms may reduce clinical risk resulting from suboptimal triage of pregnant women presenting to EDs.
