Planned mode of birth after previous caesarean section and special educational needs in childhood: a population-based record linkage cohort study.

OBJECTIVE: To investigate the association between planned mode of birth after previous caesarean section and a child's risk of having a record of special educational needs (SENs). DESIGN: Population-based cohort study. SETTING: Scotland. POPULATION: A cohort of 44 892 singleton children born at term in Scotland between 2002 and 2011 to women with one or more previous caesarean sections. METHODS: Linkage of Scottish national health and education data sets. MAIN OUTCOME MEASURES: Any SENs and specific types of SEN recorded when a child was aged 4-11 years and attending a Scottish primary or special school. RESULTS: Children born following planned vaginal birth after previous caesarean (VBAC) compared with elective repeat caesarean section (ERCS) had a similar risk of having a record of any SENs (19.24 versus 17.63%, adjusted risk ratio aRR 1.04, 95% CI 0.99-1.09) or specific types of SEN. There was also little evidence that planned VBAC with or without labour induction compared with ERCS was associated with a child's risk of having a record of any SENs (21.42 versus 17.63%, aRR 1.09, 95% CI 1.01-1.17 and 18.78 versus 17.63%, aRR 1.03, 95% CI 0.98-1.08, respectively) or most types of SEN. However, an increased risk of sensory impairment was seen for planned VBAC with labour induction compared with ERCS (1.18 versus 0.78%, risk difference 0.4%, adjusted odds ratio aOR 1.60, 95% CI 1.09-2.34). CONCLUSIONS: This study provides little evidence of an association between planned mode of birth after previous caesarean and SENs in childhood beyond a small absolute increased risk of sensory impairment seen for planned VBAC with labour induction. This finding may be the result of performing multiple comparisons or residual confounding. The findings provide valuable information to manage and counsel women with previous caesarean section concerning their future birth choices. TWEETABLE ABSTRACT: There is little evidence planned mode of birth after previous caesarean section is associated with special educational needs in childhood.

Perinatal mental health in India: protocol for a validation and cohort study.

BACKGROUND: Common mental disorders (CMD) are among the largest contributors to global maternal morbidity and mortality. Although research on perinatal mental health in India has grown in recent years, important evidence gaps remain, especially regarding CMD. Our study aims to improve understanding of CMD among perinatal and non-perinatal women of reproductive age across two settings in India: Bangalore (Karnataka) and Tanda (Himachal Pradesh). METHODS: The study is embedded within the Maternal and Perinatal Health Research Collaboration India (MaatHRI). This mixed-methods observational study comprises three consecutive phases: (i) focus group discussions and individual interviews to explore women's knowledge and seek feedback on CMD screening tools; (ii) validation of CMD screening tools; and (iii) prospective cohort study to identify CMD incidence, prevalence and risk factors among perinatal and non-perinatal women. Results of the three phases will be analyzed using inductive thematic analysis, psychometric analysis and multivariable regression analysis, respectively. CONCLUSION: Improving understanding, detection and management of CMD among women is key to improving women's health and promoting gender equality. This study will provide evidence of CMD screening tools for perinatal and non-perinatal women in two diverse Indian settings, produce data on CMD prevalence, incidence and risk factors and enhance understanding of the specific contribution of the perinatal state to CMD.

Intrapartum-related perinatal deaths in births planned in midwifery-led settings in Great Britain: findings and recommendations from the ESMiE confidential enquiry.

OBJECTIVE: To review quality of care in births planned in midwifery-led settings, resulting in an intrapartum-related perinatal death. DESIGN: Confidential enquiry. SETTING: England, Scotland and Wales. SAMPLE: Intrapartum stillbirths and intrapartum-related neonatal deaths in births planned in alongside midwifery units, freestanding midwifery units or at home, sampled from national perinatal surveillance data for 2015/16 (alongside midwifery units) and 2013-16 (freestanding midwifery units and home births). METHODS: Multidisciplinary panels reviewed medical notes for each death, assessing and grading quality of care by consensus, with reference to national standards and guidance. Data were analysed using thematic analysis and descriptive statistics. RESULTS: Sixty-four deaths were reviewed, 30 stillbirths and 34 neonatal deaths. At the start of labour care, 23 women were planning birth in an alongside midwifery unit, 26 in a freestanding midwifery unit and 15 at home. In 75% of deaths, improvements in care were identified that may have made a difference to the outcome for the baby. Improvements in care were identified that may have made a difference to the mother's physical and psychological health and wellbeing in 75% of deaths. Issues with care were identified around risk assessment and decisions about planning place of birth, intermittent auscultation, transfer during labour, resuscitation and neonatal transfer, follow up and local review. CONCLUSIONS: These confidential enquiry findings do not address the overall safety of midwifery-led settings for healthy women with straightforward pregnancies, but suggest areas where the safety of care can be improved. Maternity services should review their care with respect to our recommendations. TWEETABLE ABSTRACT: Confidential enquiry of intrapartum-related baby deaths highlights areas where care in midwifery-led settings can be made even safer.

Anaphylaxis in pregnancy: a population-based multinational European study.

Anaphylaxis in pregnancy is a rare but severe complication for both mother and infant. Population-based data on anaphylaxis in pregnancy are lacking from mainland European countries. This multinational study presents the incidence, causative agents, management and maternal and infant outcomes of anaphylaxis in pregnancy. This descriptive multinational study used a combination of retrospective (Finnish medical registries) and prospective population-based studies (UK, France, Belgium and the Netherlands) to identify cases of anaphylaxis. Sixty-five cases were identified among 4,446,120 maternities (1.5 per 100,000 maternities; 95%CI 1.1-1.9). The incidence did not vary between countries. Approximately three-quarters of reactions occurred at the time of delivery. The most common causes were antibiotics in 27 women (43%), and anaesthetic agents in 11 women (17%; including neuromuscular blocking drugs, 7), which varied between countries. Anaphylaxis had very poor outcomes for one in seven mothers and one in seven babies; the maternal case fatality rate was 3.2% (95%CI 0.4-11.0) and the neonatal encephalopathy rate was 14.3% (95%CI 4.8-30.3). Across Europe, anaphylaxis related to pregnancy is rare despite having a multitude of causative agents and different antibiotic prophylaxis protocols.

Healthcare and wider societal implications of stillbirth: a population-based cost-of-illness study.

OBJECTIVE: To extend previous work and estimate health and social care costs, litigation costs, funeral-related costs, and productivity losses associated with stillbirth in the UK. DESIGN: A population-based cost-of-illness study using a synthesis of secondary data. SETTING: The National Health Service (NHS) and wider society in the UK. POPULATION: Stillbirths occurring within a 12-month period and subsequent events occurring over the following 2 years. METHODS: Costs were estimated using published data on events, resource use, and unit costs. MAIN OUTCOME MEASURES: Mean health and social care costs, litigation costs, funeral-related costs, and productivity costs for 2 years, reported for a single stillbirth and at a national level. RESULTS: Mean health and social care costs per stillbirth were £4191. Additionally, funeral-related costs were £559, and workplace absence (parents and healthcare professionals) was estimated to cost £3829 per stillbirth. For the UK, the annual health and social care costs were estimated at £13.6 million, and total productivity losses amounted to £706.1 million (98% of this cost was attributable to the loss of the life of the baby). The figures for total productivity losses were sensitive to the perspective adopted about the loss of life of the baby. CONCLUSION: This work expands the current intelligence on the costs of stillbirth beyond the health service to costs for parents and society, and yet these additional findings must still be regarded as conservative estimates of the true economic costs. TWEETABLE ABSTRACT: The costs of stillbirth are significant, affecting the health service, parents, professionals, and society. PLAIN LANGUAGE SUMMARY: Why and how was the study carried out? The personal, social, and emotional consequences of stillbirth are profound. Placing a monetary value on such consequences is emotive, yet necessary, when deciding how best to invest limited healthcare resources. We estimated the average costs associated with a single stillbirth and the costs for all stillbirths occurring in the UK over a 1-year period. What were the main findings? The average cost to the National Health Service (NHS) of care related to the stillbirth and a first subsequent pregnancy was £4191 for each stillbirth. For the UK, this cost was £13.6 million annually. Clinical negligence payments to bereaved parents were estimated at £2.5 million per year. Parents were estimated to spend £1.8 million per year on funerals. The cost of workplace absence as parents cope with the effects of grief was estimated at £2476 per stillbirth. For the UK, this cost was £8.1 million annually. The loss of a baby is also the loss of an individual with the potential to become a valued and productive member of society. The expected value of an adult's lifetime working hours was taken as an estimate of this productivity loss, and was £213,304 for each stillbirth. The annual cost for all stillbirths was £694 million. We know from parents that the birth of a subsequent child in no way replaces a stillborn baby. We found that 52% of women fall pregnant within 12 months of a stillbirth. From a purely economic perspective concerned only with the number of individuals in society, babies born during this period could potentially replace the productivity losses of the stillborn baby. Adopting this approach, which we understand is controversial and difficult for bereaved parents, the expected productivity losses would be lower, at £333 million. What are the limitations of the work? For some categories, existing data were unavailable and we used clinical opinion to estimate costs. Furthermore, we were unable to quantify some indirect consequences, for example the psychological distress experienced by wider family members. What is the implication for parents? Placing a monetary value on what is for parents a profound personal tragedy may seem unkind. It is, however, unavoidable if we are to provide policy makers with vital information on the wide-ranging consequences that could be prevented through future investments in initiatives to reduce stillbirth.

The incidence, characteristics, management and outcomes of anaphylaxis in pregnancy: a population-based descriptive study.

OBJECTIVE: The aim of this study was to estimate the incidence of anaphylaxis in pregnancy and describe the management and outcomes in the UK. DESIGN: A population-based descriptive study using the UK Obstetric Surveillance System (UKOSS). SETTING: All consultant-led maternity units in the UK. POPULATION: All pregnant women who had anaphylaxis between 1 October 2012 and 30 September 2015. Anaphylaxis was defined as a severe, life-threatening generalised or systemic hypersensitivity reaction. METHODS: Prospective case notification using UKOSS. MAIN OUTCOME MEASURES: Maternal mortality, severe maternal morbidity, neonatal mortality and severe neonatal morbidity. RESULTS: There were 37 confirmed cases of anaphylaxis in pregnancy, giving an estimated incidence of 1.6 (95% CI: 1.1-2.2) per 100 000 maternities. Four cases of anaphylaxis were in women with known penicillin allergies: two received co-amoxiclav and two cephalosporins. Twelve women had anaphylaxis following prophylactic use of antibiotics at the time of a caesarean delivery. Prophylactic use of antibiotics for Group B streptococcal infection accounted for anaphylaxis in one woman. Two women died (5%), 14 (38%) women were admitted to intensive care and seven women (19%) had one or more additional severe maternal morbidities, which included three haemorrhagic events, two cardiac arrests, one thrombotic event and one pneumonia. No infants died; however, in those infants whose mother had anaphylaxis before delivery (n = 18) there were seven (41%) neonatal intensive care unit admissions, three preterm births and one baby was cooled for neonatal encephalopathy. CONCLUSIONS: Anaphylaxis is a rare severe complication of pregnancy and frequently the result of a reaction to antibiotic administration. This study highlights the seriousness of the outcomes of this condition for the mother. The low incidence is reassuring given the large proportion of the pregnant population that receive prophylactic antibiotics during delivery. TWEETABLE ABSTRACT: Anaphylaxis is a rare severe complication of pregnancy and frequently the result of a reaction to antibiotic administration.

Resident consultant obstetrician presence on the labour ward versus other models of consultant cover: a systematic review of intrapartum outcomes.

BACKGROUND: Several key policy documents have advocated 24-hour consultant obstetrician presence on the labour ward as a means of improving the safety of birth. However, it is unclear what published evidence exists comparing the outcomes of intrapartum care with 24-hour consultant labour ward presence and other models of consultant cover. OBJECTIVES: To collate and critically appraise evidence of the effect of continuous resident consultant obstetrician cover on the labour ward on outcomes of intrapartum care compared with other models of consultant cover. SEARCH STRATEGY: Studies were included which quantitatively compared intrapartum outcomes for women and babies where continuous resident consultant obstetric cover was provided with other models of consultant cover. SELECTION CRITERIA: Quantitative studies within healthcare systems with mixed obstetric-midwifery models of care. DATA COLLECTION AND ANALYSIS: Two researchers independently screened titles and full-text publications, extracted data and assessed the quality of included studies. Meta-analysis was performed using REVIEW MANAGER 5.3. MAIN RESULTS: About 1508 publications were screened resulting in two papers, three conference abstracts and one letter being included. All were single-site time-period comparison studies. The quality of studies overall was poor with significant risk of bias. The only significant finding in meta-analysis related to instrumental deliveries, which occurred more frequently when there was on-call consultant cover (unadjusted risk ratio 1.14; 95% CI 1.04-1.24). CONCLUSION: No reliable evidence of the effects of 24-hour resident consultant presence on the labour ward on intrapartum outcomes was identified. TWEETABLE ABSTRACT: More robust research is needed to assess intrapartum outcomes with resident consultant labour ward presence.

Pregnancy at very advanced maternal age: a UK population-based cohort study.

OBJECTIVES: To describe the characteristics, management and outcomes of women giving birth at advanced maternal age (≥48 years). DESIGN: Population-based cohort study using the UK Obstetric Surveillance System (UKOSS). SETTING: All UK hospitals with obstetrician-led maternity units. POPULATION: Women delivering at advanced maternal age (≥48 years) in the UK between July 2013 and June 2014 (n = 233) and 454 comparison women. METHODS: Cohort and comparison group identification through the UKOSS monthly mailing. MAIN OUTCOME MEASURES: Pregnancy complications. RESULTS: Older women were more likely than comparison women to be overweight (33% versus 23%, P = 0.0011) or obese (23% versus 19%, P = 0.0318), nulliparous (53% versus 44%, P = 0.0299), have pre-existing medical conditions (44% versus 28%, P < 0.0001), a multiple pregnancy (18% versus 2%, P < 0.0001), and conceived following assisted conception (78% versus 4%, P < 0.0001). Older women appeared more likely than comparison women to have pregnancy complications including gestational hypertensive disorders, gestational diabetes, postpartum haemorrhage, caesarean delivery, iatrogenic and spontaneous preterm delivery on univariable analysis and after adjustment for demographic and medical factors. However, adjustment for multiple pregnancy or use of assisted conception attenuated most effects, with significant associations remaining only with gestational diabetes (adjusted odds ratio [aOR] 4.81, 95% CI 1.93-12.00), caesarean delivery (aOR 2.78, 95% CI 1.44-5.37) and admission to an intensive care unit (aOR 33.53, 95% CI 2.73-412.24). CONCLUSIONS: Women giving birth at advanced maternal age have higher risks of a range of pregnancy complications. Many of the increased risks appear to be explained by multiple pregnancy or use of assisted conception. TWEETABLE ABSTRACT: The pregnancy complications in women giving birth aged 48 or over are mostly explained by multiple pregnancy.

Risk factors and newborn outcomes associated with maternal deaths in the UK from 2009 to 2013: a national case-control study.

OBJECTIVES: To identify the risk factors for and adverse newborn outcomes associated with maternal deaths from direct and indirect causes in the UK. DESIGN: Unmatched case-control analysis. SETTING: All hospitals caring for pregnant women in the UK. POPULATION: Comprised 383 women who died (cases) from direct or indirect causes from 2009 to 2013 (Confidential Enquiry into Maternal Deaths in the UK) and 1516 women who did not have any life-threatening complications during pregnancy and childbirth (controls) obtained from UK Obstetric Surveillance System (UKOSS). METHODS: Multivariable regression analyses were undertaken to examine potential risk factors, their incremental effects, and adverse newborn outcomes associated with maternal deaths. OUTCOMES: Odds ratios associated for risk factors for maternal death and newborn outcomes (stillbirth, admission to neonatal intensive care unit [NICU], early neonatal death) and incremental risk. RESULTS: Seven factors, of 13 examined, were independently associated with increased odds of maternal death: pre-existing medical comorbidities (adjusted odds ratio [aOR] 8.65; 95% CI 6.29-11.90), anaemia during pregnancy (aOR 3.58; 95% CI 1.14-11.21), previous pregnancy problems (aOR 1.85; 95% CI 1.33-2.57), inadequate use of antenatal care (aOR 46.85; 95% CI 19.61-111.94), substance misuse (aOR 12.21; 95% CI 2.33-63.98), unemployment (aOR 1.81; 95% CI 1.08-3.04) and maternal age (aOR 1.06; 95% CI 1.04-1.09). There was a four-fold increase in the odds of death per unit increase in the number of risk factors. Odds of stillbirth, admission to NICU and early neonatal death were higher among women who died. CONCLUSION: This study reiterates the need for optimal care for women with medical comorbidities and older age, and the importance of adequate antenatal care. It demonstrates the existence of socio-economic inequalities in maternal death in the UK. TWEETABLE ABSTRACT: Medical comorbidities and socio-economic inequalities are important risk factors for maternal death in the UK.

Incidence, risk factors, management and outcomes of amniotic-fluid embolism: a population-based cohort and nested case-control study.

OBJECTIVE: To describe the incidence, risk factors, management and outcomes of amniotic-fluid embolism (AFE) over time. DESIGN: A population-based cohort and nested case-control study using the UK Obstetric Surveillance System (UKOSS). SETTING: All UK hospitals with obstetrician-led maternity units. POPULATION: All women diagnosed with AFE in the UK between February 2005 and January 2014 (n = 120) and 3839 control women. METHODS: Prospective case and control identification through UKOSS monthly mailing. MAIN OUTCOME MEASURES: Amniotic-fluid embolism, maternal death or permanent neurological injury. RESULTS: The total and fatal incidence of AFE, estimated as 1.7 and 0.3 per 100 000, respectively, showed no significant temporal trend over the study period and there was no notable temporal change in risk factors for AFE. Twenty-three women died (case fatality 19%) and seven (7%) of the surviving women had permanent neurological injury. Women who died or had permanent neurological injury were more likely to present with cardiac arrest (83% versus 33%, P < 0.001), be from ethnic-minority groups (adjusted odds ratio [OR] 2.85, 95% confidence interval [95% CI] 1.02-8.00), have had a hysterectomy (unadjusted OR 2.49, 95% CI 1.02-6.06), had a shorter time interval between the AFE event and when the hysterectomy was performed (median interval 77 minutes versus 248 minutes, P = 0.0315), and were less likely to receive cryoprecipitate (unadjusted OR 0.30, 95% CI 0.11-0.80). CONCLUSION: There is no evidence of a temporal change in the incidence of or risk factors for AFE. Further investigation is needed to establish whether earlier treatments can reverse the cascade of deterioration leading to severe outcomes.

Experiences, utilisation and outcomes of maternity care in England among women from different socio-economic groups: findings from the 2010 National Maternity Survey.

OBJECTIVE: The objective of this analysis was to explore the healthcare-seeking behaviours and experiences of maternity care among women from different socio-economic groups in order to improve understanding of why socially disadvantaged women have poorer maternal health outcomes in the UK. DESIGN: Secondary analysis of a national survey of women conducted 3 months after they had given birth. SETTING: England. SAMPLE: A total of 5332 women. METHODS: Logistic regression analysis to investigate differences in outcomes among different socio-economic groups, classified by the Index of Multiple Deprivation (IMD). MAIN OUTCOME MEASURES: Healthcare-seeking behaviours, outcomes and experiences of maternity care. RESULTS: With each increase in IMD quintile (decrease in socio-economic position), women were shown to be 25% (adjusted odds ratio [aOR] 0.75; 95% confidence interval [95% CI] 0.63-0.90) less likely to have had any antenatal care and 15% (aOR 0.85; 95% CI 0.80-0.90) less likely to have had a routine postnatal check-up. They were 4% (aOR 1.04; 95% CI 0.99-1.10) more likely to have had an antenatal hospital admission, 7% (aOR 1.07; 95% CI 0.99-1.16) more likely to have been transferred during labour and 4% (aOR 1.04; 95% CI 0.99-1.09) more likely to have had a caesarean birth, although these results were not statistically significant. With decreasing socio-economic position women were more likely to report that they were not treated respectfully or spoken to in a way they could understand by doctors and midwives. CONCLUSIONS: This analysis suggests the need for a focusing of professionals and services towards pregnant women from lower socio-economic groups and more targeted maternal public health education towards socially disadvantaged women.

Progression from severe sepsis in pregnancy to death: a UK population-based case-control analysis.

OBJECTIVE: To identify factors associated with progression from pregnancy-associated severe sepsis to death in the UK. DESIGN: A population-based case-control analysis using data from the UK Obstetric Surveillance System (UKOSS) and the UK Confidential Enquiry into Maternal Death (CEMD). SETTING: All pregnancy care and death settings in UK hospitals. POPULATION: All non-influenza sepsis-related maternal deaths (January 2009 to December 2012) were included as cases (n = 43), and all women who survived severe non-influenza sepsis in pregnancy (June 2011 to May 2012) were included as controls (n = 358). METHODS: Cases and controls were identified using the CEMD and UKOSS. Multivariable logistic regression was used to estimate adjusted odds ratios (aOR) with 95% confidence intervals. MAIN OUTCOME MEASURES: Odds ratios for socio-demographic, medical, obstetric and management factors in women who died from sepsis, compared with those who survived. RESULTS: Four factors were included in the final regression model. Women who died were more likely to have never received antibiotics [aOR = 22.7, 95% confidence interval (CI) 3.64-141.6], to have medical comorbidities (aOR = 2.53, 95%CI 1.23-5.23) and to be multiparous (aOR = 3.57, 95%CI 1.62-7.89). Anaemia (aOR = 13.5, 95%CI 3.17-57.6) and immunosuppression (aOR = 15.0, 95%CI 1.93-116.9) were the two most important factors driving the association between medical comorbidities and progression to death. CONCLUSIONS: There must be continued vigilance for the risks of infection in pregnant women with medical comorbidities. Improved adherence to national guidelines, alongside prompt recognition and treatment with antibiotics, may reduce the burden from sepsis-related maternal deaths. TWEETABLE ABSTRACT: Medical comorbidities, multiparity and antibiotic delays increase the risk of death from maternal sepsis.

Factors associated with maternal death from direct pregnancy complications: a UK national case-control study.

OBJECTIVE: To investigate the factors associated with maternal death from direct pregnancy complications in the UK. DESIGN: Unmatched case-control analysis. SETTING: All hospitals caring for pregnant women in the UK. POPULATION: A total of 135 women who died (cases) between 2009 and 2012 from eclampsia, pulmonary embolism, severe sepsis, amniotic fluid embolism, and peripartum haemorrhage, using data from the Confidential Enquiry into Maternal Death, and another 1661 women who survived severe complications (controls) caused by these conditions (2005-2013), using data from the UK Obstetric Surveillance System. METHODS: Multivariable regression analyses were undertaken to identify the factors that were associated with maternal deaths and to estimate the additive odds associated with the presence of one or more of these factors. MAIN OUTCOME MEASURES: Odds ratios associated with maternal death and population-attributable fractions, with 95% confidence intervals. Incremental risk of death associated with the factors using a 'risk factors' score. RESULTS: Six factors were independently associated with maternal death: inadequate use of antenatal care (adjusted odds ratio, aOR 15.87, 95% CI 6.73-37.41); substance misuse (aOR 10.16, 95% CI 1.81-57.04); medical comorbidities (aOR 4.82, 95% CI 3.14-7.40); previous pregnancy problems (aOR 2.21, 95% CI 1.34-3.62); hypertensive disorders of pregnancy (aOR 2.44, 95% CI 1.31-4.52); and Indian ethnicity (aOR 2.70, 95% CI 1.14-6.43). Of the increased risk associated with maternal death, 70% (95% CI 66-73%) could be attributed to these factors. Odds associated with maternal death increased by three and a half times per unit increase in the 'risk factor' score (aOR 3.59, 95% CI 2.83-4.56). CONCLUSIONS: This study shows that medical comorbidities are importantly associated with direct (obstetric) deaths. Further studies are required to understand whether specific aspects of care could be improved to reduce maternal deaths among women with medical comorbidities in the UK.

Maternal near-miss case reviews: the UK approach.

The UK has a well-established programme of Confidential Enquiries into Maternal Deaths and a national system for research into near-miss maternal morbidities, the UK Obstetric Surveillance System. The addition of a programme of near-miss case reviews, the Confidential Enquiries into Maternal Morbidity, permits a complete examination of the incidence, risk factors, care and outcomes of the severest complications in pregnancy, and enables the lessons learnt to improve future care to be identified more quickly. This in turn allows for more rapid inclusion of recommendations into national guidance and hence the potential of better health for both women and babies.

The management and outcomes of placenta accreta, increta, and percreta in the UK: a population-based descriptive study.

OBJECTIVE: To describe the management and outcomes of placenta accreta, increta, and percreta in the UK. DESIGN: A population-based descriptive study using the UK Obstetric Surveillance System (UKOSS). SETTING: All 221 UK hospitals with obstetrician-led maternity units. POPULATION: All women diagnosed with placenta accreta, increta, and percreta in the UK between May 2010 and April 2011. METHODS: Prospective case identification through the monthly mailing of UKOSS. MAIN OUTCOME MEASURES: Median estimated blood loss, transfusion requirements. RESULTS: A cohort of 134 women were identified with placenta accreta, increta, or percreta: 50% (66/133) were suspected to have this condition antenatally. In women with a final diagnosis of placenta increta or percreta, antenatal diagnosis was associated with reduced levels of haemorrhage (median estimated blood loss 2750 versus 6100 ml, P = 0.008) and a reduced need for blood transfusion (59 versus 94%, P = 0.014), possibly because antenatally diagnosed women were more likely to have preventative therapies for haemorrhage (74 versus 52%, P = 0.007), and were less likely to have an attempt made to remove their placenta (59 versus 93%, P < 0.001). Making no attempt to remove any of the placenta, in an attempt to conserve the uterus or prior to hysterectomy, was associated with reduced levels of haemorrhage (median estimated blood loss 1750 versus 3700 ml, P = 0.001) and a reduced need for blood transfusion (57 versus 86%, P < 0.001). CONCLUSIONS: Women with placenta accreta, increta, or percreta who have no attempt to remove any of their placenta, with the aim of conserving their uterus, or prior to hysterectomy, have reduced levels of haemorrhage and a reduced need for blood transfusion, supporting the recommendation of this practice.

Eclampsia, a comparison within the International Network of Obstetric Survey Systems.

OBJECTIVE: To compare incidences, characteristics, management and outcome of eclampsia in the Netherlands and the UK. DESIGN: A comparative analysis of two population-based prospective cohort studies. SETTING: All hospitals with consultant-led maternity units. POPULATION: Women with eclampsia in the Netherlands (226) and the UK (264). METHODS: Comparison of individual level data from national studies in the Netherlands and the UK (LEMMoN 2004-06; UKOSS 2005/06). MAIN OUTCOME MEASURES: Incidence, maternal complications and differences in management strategies. RESULTS: Incidences of eclampsia differed significantly between both countries: the Netherlands 5.4/10,000 deliveries versus UK 2.7/10,000 (relative risk [RR] 1.94, 95% confidence intervals [95% CI] 1.6-2.4). The proportion of women with a preceding diagnosis of pre-eclampsia was comparable between both countries (the Netherlands 42%; UK 43%), as was the proportion who received magnesium sulphate prophylaxis. Women in the Netherlands had a significantly higher maximum diastolic blood pressure (111 mmHg versus 95 mmHg, P < 0.001); significantly fewer received anti-hypertensive medication (16% versus 71%; RR 0.2, 95% CI 0.1-0.3) and were treated less often with magnesium sulphate after their first fit (95% versus 99%; RR 0.96, 95% CI 0.92-0.99). Maternal death occurred in three cases in the Netherlands compared with zero in the UK. CONCLUSIONS: The incidence of eclampsia in the Netherlands was twice as high compared with the UK when using uniform definitions. Women with eclampsia in the Netherlands were not managed according to guidelines, particularly with respect to blood pressure management. Changes in management practice may reduce both incidence and poor outcomes.

Experiences with maternal and perinatal death reviews in the UK--the MBRRACE-UK programme.

Established in 1952, the programme of surveillance and Confidential Enquiries into Maternal Deaths in the UK is the longest running such programme worldwide. Although more recently instituted, surveillance and confidential enquiries into perinatal deaths are also now well established nationally. Recent changes to funding and commissioning of the Enquiries have enabled both a reinvigoration of the processes and improvements to the methodology with an increased frequency of future reporting. Close engagement with stakeholders and a regulator requirement for doctors to participate have both supported the impetus for involvement of all professionals leading to greater potential for improved quality of care for women and babies.

Asthma in children born after infertility treatment: findings from the UK Millennium Cohort Study.

STUDY QUESTION: Is asthma more common in children born after subfertility and assisted reproduction technologies (ART)? SUMMARY ANSWER: Yes. Asthma, wheezing in the last year and anti-asthmatic medication were all more common in children born after a prolonged time to conception (TTC). This was driven specifically by an increase in children born after ART. WHAT IS KNOWN ALREADY: Few studies have investigated any association between ART and asthma in subsequent children, and findings to date have been mixed. A large registry-based study found an increase in asthma medication in ART children but suggests underlying infertility is the putative risk factor. Little is known about asthma in children after unplanned or mistimed conceptions. STUDY DESIGN, SIZE, DURATION: The Millennium Cohort Study is a UK-wide, prospective study of 18 818 children recruited at 9 months of age. Follow-up is ongoing. This study analyses data from follow-up surveys at 5 and 7 years of age (response rates of 79 and 70%, respectively). PARTICIPANTS/MATERIALS, SETTING, METHODS: Singleton children whose natural mothers provided follow-up data were included. Mothers reported whether their pregnancy was planned; planners provided TTC and details of any ART. The population was divided into 'unplanned' (unplanned and unhappy), 'mistimed' (unplanned but happy), 'planned' (planned, TTC < 12 months), 'untreated subfertile' (planned, TTC >12 months), 'ovulation induced' (received clomiphene citrate) and 'ART' (IVF or ICSI). The primary analysis used the planned children as the comparison group; secondary analysis compared the treatment groups to the children born to untreated subfertile parents. Outcomes were parent report of asthma and wheezing at 5 and 7 years, derived from validated questions in the International Study of Asthma and Allergies in Childhood, plus use of anti-asthmatic medications. A total of 13 041 (72%) children with full data on asthma and confounders were included at 5 years of age, and 11 585 (64%) at 7 years. MAIN RESULTS AND THE ROLE OF CHANCE: Compared with planned children, those born to subfertile parents were significantly more likely to experience asthma, wheezing and to be taking anti-asthmatics at 5 years of age [adjusted odds ratio (OR): 1.39 (95% confidence interval (CI): 1.07, 1.80), OR: 1.27 (1.00, 1.63) and OR: 1.90 (1.32,2.74), respectively]. This association was mainly related to an increase among children born after ART (adjusted OR: 2.65 (1.48, 4.76), OR: 1.97, (1.10, 3.53) and OR: 4.67 (2.20, 9.94) for asthma, wheezing and taking anti-asthmatics, respectively). The association was also present, though reduced, at the age of 7 years. LIMITATIONS, REASONS FOR CAUTION: The number of singletons born after ART was relatively small (n = 104), and as such the findings should be interpreted with caution. However, data on a wide range of possible confounding and mediating factors were available and analysed. The data were weighted for non-response to minimize selection bias. WIDER IMPLICATIONS OF THE FINDINGS: The findings add to the growing body of evidence suggesting an association between subfertility, ART and asthma in children. Further work is needed to establish causality and elucidate the underlying mechanism. These findings are generalizable to singletons only, and further work on multiples is needed.

Contemporary management and outcomes for infants born with oesophageal atresia.

BACKGROUND: Reports on the management and outcome of rare conditions, such as oesophageal atresia, are frequently limited to case series reporting single-centre experience over many years. The aim of this study was to identify all infants born with oesophageal atresia in the UK and Ireland to describe current clinical practice and outcomes. METHODS: This was a prospective multicentre cohort study of all infants born with oesophageal atresia and/or tracheo-oesophageal fistula in 2008-2009 in the UK and Ireland to record current clinical management and early outcomes. RESULTS: A total of 151 infants admitted to 28 paediatric surgical units were identified. Some aspects of perioperative management were universal, including oesophageal decompression, operative technique and the use of transanastomotic tubes. However, there were a number of areas where clinical practice varied considerably, including the routine use of perioperative chest drains, postoperative contrast studies and antireflux medication, with each of these being employed in 30-50 per cent of patients. There was a trend towards routine postoperative ventilation. CONCLUSION: The prospective methodology used in this study can help identify practices that all surgeons employ and also those that few surgeons use. Areas of clinical equipoise can be recognized and avenues for further research identified.

Transfers of women planning birth in midwifery units: data from the birthplace prospective cohort study.

OBJECTIVE: To examine the percentage of women transferred, reasons for transfer and factors associated with the transfer of women planning birth in midwifery units (MUs). DESIGN: Prospective cohort study. SETTING: All freestanding midwifery units (FMUs) and alongside midwifery units (AMUs) in England. PARTICIPANTS: Twenty-nine thousand, two hundred and forty-eight eligible women with a singleton, term and 'booked' pregnancy, planning birth in an MU between April 2008 and April 2010. METHODS: Multivariable logistic regression was used to explore the sociodemographic and clinical characteristics associated with transfer. MAIN OUTCOME MEASURES: Transfer during labour or within 24 hours of birth. RESULTS: Over one in four women were transferred from AMUs and over one in five from FMUs. In both types of MU, compared with multiparous women aged 25-29 years, nulliparous women aged <20 years had higher odds of transfer (FMU-adjusted odds ratio [OR], 4.5; 95% confidence interval [CI], 3.10-6.57; AMU-adjusted OR, 2.6; 95% CI, 2.18-2.06), and the odds of transfer increased with increasing age. Nulliparous women aged ≥ 35 years in FMUs had 7.4 times the odds of transfer (95% CI, 5.43-10.10) and, in AMUs, 6.0 times the odds of transfer (95% CI, 4.81-7.41). Starting labour care after 40 weeks of gestation and the presence of complicating conditions at the start of labour care were also independently associated with a higher risk of transfer. CONCLUSIONS: Transfer from MUs is common, especially for first-time mothers. This study provides evidence on the maternal characteristics associated with an increased risk of transfer, which can be used to inform women's choices about place of birth.
