Long-term psychological impact of severe postpartum hemorrhage

Why is ethnicity a risk factor for postpartum haemorrhage?

Postpartum haemorrhage (PPH) is a leading cause of maternal mortality and morbidity on a global scale. Ethnic background is known to be a determinant of variation in the outcomes of women receiving maternity care across the world. Despite free maternity healthcare in the UK National Health Service, women with an ethnic minority background giving birth have an increased risk of PPH, even when other characteristics of the mother, the baby and the care received are considered. Improving PPH care has significant implications for improving health equity. The underlying causes of ethnic disparities are complex and multifaceted. It requires a deep dive into analysing the unique patient factors that make these women more likely to suffer from a PPH as well as reflecting on the efficacy of intra and postpartum care and prophylactic treatment these women receive.

Short and long-term menstrual, reproductive, and mental health outcomes after the intrauterine use of chitosan tamponade or the Bakri balloon for severe postpartum hemorrhage: an observational study

OBJECTIVE

This retrospective follow-up study analyzes the effect of intrauterine postpartum hemorrhage (PPH) therapy on menstrual, reproductive, and mental health outcomes.

METHODS

All women who delivered at a university hospital between 2016 and 2021 with PPH and who needed intrauterine therapy were included. A questionnaire on well-being, menses, fertility, and reproductive outcomes was mailed to the patients. Those who did not reply were surveyed by telephone.

RESULTS

A total of 214 women treated with chitosan-covered gauze (group A) and 46 women treated with a balloon tamponade (group B) were recruited, and their short-term courses were analyzed. For long-term follow-up, 71 women of group A (33%) and 21 women of group B (46%) could be reached. A total of 89% of group A and 95% of group B had regular menstrual bleeding in the most recent 12 months; 27% (group A) and 29% (group B) were trying to conceive again, and all of them did so successfully. There were 12 deliveries, 3 ongoing pregnancies, 3 miscarriages, and 2 terminations of pregnancies (TOP) in group A and 4 deliveries, 1 miscarriage, and 2 TOPs in group B. More than half of our study participants was sorted into grade II or III of the Impact of Events Scale, indicating they experienced clinical impacts in the form of psychological sequelae. One-quarter of patients had symptoms of post-traumatic stress disorder.

CONCLUSION

Chitosan gauze as well as balloon tamponade appear to have few adverse effects on subsequent menstrual and reproductive function. Women after PPH are at increased risk of long-term adverse psychological outcomes.

Patient Perception of Care, Outcomes, and Consequences from Placenta Accreta Spectrum: A Survey-Based Study

OBJECTIVE

Placenta accreta spectrum (PAS) is an obstetric diagnosis that carries significant risks. However, little is known about patient perceptions of care. This study was conducted to describe the patient experience, reported outcomes, and assess geographical variation in PAS care in the United States.

STUDY DESIGN

Partnering with a PAS patient advocacy organization, we conducted an online survey of PAS patients. Perceptions of care and outcomes, and geographic variation were described.

RESULTS

We received 108 responses (69% response rate); 103 respondents delivered in the United States. Demographic characteristics were similar across each region. Most (67%) reported at least one prior cesarean delivery and 53% reported placenta previa in the PAS pregnancy. Over half (63%) reported an antenatal suspicion of PAS and 66% of those respondents reported changing their delivery hospital as a result of their antenatal diagnosis. Though not statistically significant, both showed variability across regions (both p ≥0.60). Seventy-five percent of respondents with antenatal diagnosis reported their pregnancy was managed by a dedicated PAS care team, which did not differ by region (p = 0.80). A majority of respondents (75%) felt their PAS care team was prepared for their delivery; this too did not vary across regions (p = 0.97). Many respondents reported at least one physical (63%) or mental health (17%) adverse outcome as a result of their PAS pregnancy.

CONCLUSION

As reported by prior PAS patients, perception of care and outcomes are overall favorable. There are long-term physical and mental adverse consequences reported. Geographical variation is mixed, however, national guidelines are predominately followed.

KEY POINTS

· Patient perceptions of care and outcomes are overall positive and favorable.. · Long lasting physical and mental health consequence from PAS pregnancies are commonly seen.. · Multidisciplinary care is widely adopted for PAS pregnancies..

Perceptions and experiences of the prevention, detection, and management of postpartum haemorrhage: a qualitative evidence synthesis

BACKGROUND

Postpartum haemorrhage (PPH), defined as blood loss of 500 mL or more after childbirth, is the leading cause of maternal mortality worldwide. It is possible to prevent complications of PPH with timely and appropriate detection and management. However, implementing the best methods of PPH prevention, detection and management can be challenging, particularly in low- and middle-income countries.

OBJECTIVES

Our overall objective was to explore the perceptions and experiences of women, community members, lay health workers, and skilled healthcare providers who have experience with PPH or with preventing, detecting, and managing PPH, in community or health facility settings.

SEARCH METHODS

We searched MEDLINE, CINAHL, Scopus, and grey literature on 13 November 2022 with no language restrictions. We then performed reference checking and forward citation searching of the included studies.

SELECTION CRITERIA

We included qualitative studies and mixed-methods studies with an identifiable qualitative component. We included studies that explored perceptions and experiences of PPH prevention, detection, and management among women, community members, traditional birth attendants, healthcare providers, and managers.

DATA COLLECTION AND ANALYSIS

We used three-stage maximum variation sampling to ensure diversity in terms of relevance of the study to the review objectives, richness of data, and coverage of critical contextual elements: setting (region, country income level), perspective (type of participant), and topic (prevention, detection, management). We extracted data using a data extraction form designed for this review. We used thematic synthesis to analyse and synthesise the evidence, and we used the GRADE-CERQual (Confidence in the Evidence from Reviews of Qualitative research) approach to assess our confidence in each finding. To identify factors that may influence intervention implementation, we mapped each review finding to the Theoretical Domains Framework (TDF) and the Capability, Motivation, and Opportunity model of Behaviour change (COM-B). We used the Behaviour Change Wheel to explore implications for practice.

MAIN RESULTS

We included 67 studies and sampled 43 studies for our analysis. Most were from low- or middle-income countries (33 studies), and most included the perspectives of women and health workers. We downgraded our confidence in several findings from high confidence to moderate, low, or very-low confidence, mainly due to concerns about how the studies were conducted (methodological limitations) or concerns about missing important perspectives from some types of participants or in some settings (relevance). In many communities, bleeding during and after childbirth is considered "normal" and necessary to expel "impurities" and restore and cleanse the woman's body after pregnancy and birth (moderate confidence). In some communities, people have misconceptions about causes of PPH or believe that PPH is caused by supernatural powers or evil spirits that punish women for ignoring or disobeying social rules or for past mistakes (high confidence). For women who give birth at home or in the community, female family members or traditional birth attendants are the first to recognise excess bleeding after birth (high confidence). Family members typically take the decision of whether and when to seek care if PPH is suspected, and these family members are often influenced by trusted traditional birth attendants or community midwives (high confidence). If PPH is identified for women birthing at home or in the community, decision-making about the subsequent referral and care pathway can be multifaceted and complex (high confidence). First responders to PPH are not always skilled or trained healthcare providers (high confidence). In health facilities, midwives may consider it easy to implement visual estimation of blood loss with a kidney dish or under-pad, but difficult to accurately interpret the amount of blood loss (very low confidence). Quantifying (rather than estimating) blood loss may be a complex and contentious change of practice for health workers (low confidence). Women who gave birth in health facilities and experienced PPH described it as painful, embarrassing, and traumatic. Partners or other family members also found the experience stressful. While some women were dissatisfied with their level of involvement in decision-making for PPH management, others felt health workers were best placed to make decisions (moderate confidence). Inconsistent availability of resources (drugs, medical supplies, blood) causes delays in the timely management of PPH (high confidence). There is limited availability of misoprostol in the community owing to stockouts, poor supply systems, and the difficulty of navigating misoprostol procurement for community health workers (moderate confidence). Health workers described working on the maternity ward as stressful and intense due to short staffing, long shifts, and the unpredictability of emergencies. Exhausted and overwhelmed staff may be unable to appropriately monitor all women, particularly when multiple women are giving birth simultaneously or on the floor of the health facility; this could lead to delays in detecting PPH (moderate confidence). Inadequate staffing, high turnover of skilled health workers, and appointment of lower-level cadres of health workers are key challenges to the provision of quality PPH care (high confidence). Through team-based simulation training, health workers of different cadres (doctors, midwives, lay health workers) can develop a shared mental model to help them work quickly, efficiently, and amicably as a team when managing women with PPH (moderate confidence).

AUTHORS' CONCLUSIONS

Our findings highlight how improving PPH prevention, detection, and management is underpinned by a complex system of interacting roles and behaviours (community, women, health workers of different types and with different experiences). Multiple individual, sociocultural, and environmental factors influence the decisions and behaviours of women, families, communities, health workers, and managers. It is crucial to consider the broader health and social systems when designing and implementing PPH interventions to change or influence these behaviours. We have developed a set of prompts that may help programme managers, policymakers, researchers, and other key stakeholders to identify and address factors that affect implementation and scale-up of interventions to improve PPH prevention, detection, and management.

Association of severe maternal morbidity with bonding impairment and self-harm ideation: A multicenter prospective cohort study

BACKGROUND

Evidence on the association between severe maternal morbidity (SMM) and mother-infant bonding and self-harm ideation is limited. We aimed to examine these associations and the mediating effect of Neonatal Intensive Care Unit (NICU) admission at one-month postpartum.

METHODS

This multicenter, prospective cohort study was conducted in Japan (n = 5398). SMM included preeclampsia, eclampsia, severe postpartum hemorrhage, placental abruption, and a ruptured uterus. Lack of affection (LA) and Anger and Rejection (AR) were assessed using the Mother-Infant Bonding Scale (MIBS), and self-harm ideation was assessed using the 10th item of the Edinburgh Postnatal Depression Scale (EPDS). Linear and logistic regression models were used to examine the association between SMM and MIBS score and self-harm ideation. A structural equation model (SEM) was employed to examine the mediating effect of NICU admission on the association between SMM and mother-infant bonding and postpartum depressive symptoms.

RESULTS

Women with SMM had a 0.21 (95 % confidence interval [CI]: 0.03-0.40) point higher MIBS score and a decreasing trend in the risk of self-harm ideation (odds ratio 0.28, 95 % CI: 0.07-1.14) compared to those without SMM. SEM analysis revealed that SMM was associated with MIBS partially through NICU admission.

LIMITATIONS

EPDS scores during pregnancy could be an unmeasured confounder.

CONCLUSIONS

Women with SMM had higher MIBS scores, particularly on the LA subscale, which was partially mediated by NICU admission. Psychotherapy to support parent-infant relationships is necessary for women with SMM.

Prediction of postpartum hemorrhage (PPH) using machine learning algorithms in a Kenyan population

Introduction

Postpartum hemorrhage (PPH) is a significant cause of maternal mortality worldwide, particularly in low- and middle-income countries. It is essential to develop effective prediction models to identify women at risk of PPH and implement appropriate interventions to reduce maternal morbidity and mortality. This study aims to predict the occurrence of postpartum hemorrhage using machine learning models based on antenatal, intrapartum, and postnatal visit data obtained from the Kenya Antenatal and Postnatal Care Research Collective cohort.

Method

Four machine learning models - logistic regression, naïve Bayes, decision tree, and random forest - were constructed using 67% training data (1,056/1,576). The training data was further split into 67% for model building and 33% cross validation. Once the models are built, the remaining 33% (520/1,576) independent test data was used for external validation to confirm the models' performance. Models were fine-tuned using feature selection through extra tree classifier technique. Model performance was assessed using accuracy, sensitivity, and area under the curve (AUC) of the receiver operating characteristics (ROC) curve.

Result

The naïve Bayes model performed best with 0.95 accuracy, 0.97 specificity, and 0.76 AUC. Seven factors (anemia, limited prenatal care, hemoglobin concentrations, signs of pallor at intrapartum, intrapartum systolic blood pressure, intrapartum diastolic blood pressure, and intrapartum respiratory rate) were associated with PPH prediction in Kenyan population.

Discussion

This study demonstrates the potential of machine learning models in predicting PPH in the Kenyan population. Future studies with larger datasets and more PPH cases should be conducted to improve prediction performance of machine learning model. Such prediction algorithms would immensely help to construct a personalized obstetric path for each pregnant patient, improve resource allocation, and reduce maternal mortality and morbidity.

Mental Health and Placenta Accreta Spectrum

Nearly half of women describe childbirth as traumatic in some way, making them more vulnerable to perinatal psychiatric illness. Patients with high risk pregnancies, such as abnormal placentation, are even more susceptible to childbirth related mental health sequelae. There are no formal recommendations for mental health intervention in women with placenta accreta spectrum (PAS). In many institutions, the Edinburgh Postpartum Depression Scale is used to assess for depressive and anxiety symptoms during pregnancy and postpartum. Women with PAS should be screened at time of diagnosis, monthly until delivery, and at multiple time points through the first year postpartum. It is also recommended to screen women for PTSD prior to and after delivery. Interventions shown helpful in the PAS population include establishing a multidisciplinary team, patient access to a support person or care coordinator, development of a postpartum care team and plan, and extending mental health follow up through the first year postpartum. Women with PAS are at increased risk for negative mental health outcomes. To support the mental health of women with PAS and their families, we recommend a multi-disciplinary treatment team, screening for mental health sequelae early and often, referring women with positive screens to mental health professionals, involving the partner/family in care, and considering referral to a PAS support group for peer support.

Knowledge Gaps in Placenta Accreta Spectrum

Since its first description early in the 20th Century, placenta accreta and its variants have changed substantially in incidence, risk factor profile, clinical presentation, diagnosis and management. While systematic use of diagnostic tools and a multidisciplinary team care approach has begun to improve patient outcomes, the condition's pathophysiology, epidemiology, and best practices for diagnosis and management remain poorly understood. The use of large databases with broadly accepted terminology and diagnostic criteria should accelerate research in this area. Future work should focus on non-traditional phenotypes, such as those without placenta previa-preventive strategies, and long term medical and emotional support for patients facing this diagnosis. KEY POINTS: · Placenta accreta spectrum research may be improved with standardized terminology and use of large databases.. · Placenta accreta prediction should move beyond ultrasound with the addition of biomarkers, and needs to extend to those without traditional risk factors.. · Future research should identify practices that can prevent future accreta development..

Primary postpartum haemorrhage and longer-term physical, psychological, and psychosocial health outcomes for women and their partners in high income countries: A mixed-methods systematic review

OBJECTIVES

Most research about outcomes following postpartum haemorrhage (PPH) has focused on immediate outcomes. There are fewer studies investigating longer-term maternal morbidity following PPH, resulting in a significant knowledge gap. This review aimed to synthesize the evidence about the longer-term physical and psychological consequences of primary PPH for women and their partners from high income settings.

METHODS

The review was registered with PROSPERO and five electronic databases were searched. Studies were independently screened against the eligibility criteria by two reviewers and data were extracted from both quantitative and qualitative studies that reported non-immediate health outcomes of primary PPH.

RESULTS

Data were included from 24 studies, of which 16 were quantitative, five were qualitative and three used mixed-methods. The included studies were of mixed methodological quality. Of the nine studies reporting outcomes beyond five years after birth, only two quantitative studies and one qualitative study had a follow-up period longer than ten years. Seven studies reported outcomes or experiences for partners. The evidence indicated that women with PPH were more likely to have persistent physical and psychological health problems after birth compared with women who did not have a PPH. These problems, including PTSD symptoms and cardiovascular disease, may be severe and extend for many years after birth and were more pronounced after a severe PPH, as indicated by a blood transfusion or hysterectomy. There was limited evidence about outcomes for partners after PPH, but conflicting evidence of association between PTSD and PPH among partners who witnessed PPH.

CONCLUSION

This review explored existing evidence about longer-term physical and psychological health outcomes among women who had a primary PPH in high income countries, and their partners. While the evidence about health outcomes beyond five years after PPH is limited, our findings indicate that women can experience long lasting negative impacts after primary PPH, including PTSD symptoms and cardiovascular disease, extending for many years after birth.

Psychiatric Symptoms in Women with High-risk Pregnancy in the Postpartum Period: A Case-control Study

OBJECTIVE

 Psychiatric symptoms are common mental issues in pregnancy and the postpartum period. There is limited information regarding the psychiatric symptoms of women with high-risk pregnancy in the postpartum period. This study aimed to compare the severity of psychiatric symptoms and psychological distress in women with high-risk and low-risk pregnancies in the postpartum period.

METHODS

 This case-control study examined 250 women in the postpartum period in two groups with low-risk (n = 112) and high-risk (n = 138) pregnancies. Women completed the Brief Symptom Inventory-53 (BSI-53) and the Risk Postnatal Psychosocial Depression Risk Questionnaire (PPDRQ).

RESULTS

 The mean severity of psychiatric symptoms in women with high-risk pregnancies was significantly higher than that in women with low-risk pregnancies (39.34 ± 17.51 vs. 30.26 ± 17.08). Additionally, the frequency of psychological distress in women with high-risk pregnancies was approximately twice higher than that in women with low-risk pregnancies (30.3% vs. 15.2%). Furthermore, the risk factors for depression in women with high-risk pregnancies were almost 1.5 times (59.8% vs. 39.8%) higher than the factors in women with low-risk pregnancies. The results of the logistic analysis indicated that high-risk pregnancies could be twice the odds ratio of developing postpartum psychological distress (ß = 2.14, 95% CI 1.4-6.3, p= 0.036).

CONCLUSION

 Psychiatric symptoms and the psychological distress index are higher in postpartum women with high-risk pregnancies than in postpartum women with low-risk pregnancies. The study suggests that obstetricians and pregnant women's health care providers should strongly consider screening of psychiatric symptoms in women with high-risk pregnancies both during pregnancy and after delivery as the women's routine care priorities.

Menstrual, fertility and psychological impacts after uterine compression sutures for postpartum hemorrhage: a prospective cohort study

BACKGROUND

Uterine compression suture is an important conservative surgical technique in managing atonic postpartum hemorrhage. In this study, we aim to evaluate the subsequent menstrual, fertility and psychological outcomes after uterine compression sutures.

METHODS

This was a prospective cohort study between 2009 and 2022 conducted in a tertiary obstetric unit (6000 deliveries per year) in Hong Kong SAR. Women with primary postpartum hemorrhage successfully treated with uterine compression sutures were followed-up in postnatal clinic for two years after delivery. Data on menstrual pattern were collected during each visit. Psychological impact after uterine compression suture was assessed using a standardized questionnaire. Subsequent pregnancies were identified by territory-wide computer registry and telephone interviews. Women with postpartum hemorrhage treated with uterotonic agents only were chosen as controls.

RESULTS

In our cohort (n = 80), 87.9% of women had return of menses within six months after delivery. Regular monthly cycle was observed in 95.6% of women. Majority of women reported similar menstrual flow (75%), menstrual days (85.3%) and no change in dysmenorrhea status (88.2%) as compared before. Among eight (11.8%) women who reported hypomenorrhea after uterine compression sutures, two cases of Asherman's syndrome were diagnosed. Among 23 subsequent pregnancies (16 livebirths), no significant differences in outcome were observed except more omental or bowel adhesions (37.5% vs. 8.8%, p = 0.007), recurrence of hemorrhage (68.8% vs. 7.5%, p < 0.001) and repeated compression sutures (12.5% vs. 0%, p = 0.024) were seen in women with previous compression sutures. Over half of the couple declined future fertility after uterine compression sutures with 38.2% of women recalled unpleasant memories and 22.1% reported life-long adverse impact especially tokophobia.

CONCLUSION

Majority of women with history of uterine compression sutures had similar menstruation and pregnancy outcomes as compared to those who did not have sutures. However, they had higher intrapartum risk of visceral adhesions, recurrence of hemorrhage and repeated compression sutures next pregnancy. Furthermore, couple could be more susceptible to negative emotional impact.

Incidence and predictors of severe postpartum hemorrhage after cesarean delivery in South Central Ethiopia: a retrospective cohort study

Severe postpartum hemorrhage is an obstetric emergency that needs immediate intervention and is a leading cause of maternal death. Despite its significant health burden, little is known, about its magnitude and risk factors, especially after cesarean delivery in Ethiopia. This study aimed to evaluate the incidence and predictors of severe postpartum hemorrhage following cesarean section. This study was conducted on 728 women who underwent cesarean section. We retrospectively collected data from the medical records, including baseline characteristics, obstetrics, and perioperative data. Potential predictors were investigated using multivariate logistic regression analyses, adjusted odd ratios, and a 95% confidence interval to see associations. A p-value < 0.05 is considered statistically significant. The incidence of severe postpartum hemorrhage was 26 (3.6%). The independently associated factors were previous CS scar ≥ 2 (AOR 4.08: 95% CI 1.20-13.86), antepartum hemorrhage (AOR 2.89: 95% CI 1.01-8.16), severe preeclampsia (AOR 4.52: 95% CI 1.24-16.46), maternal age ≥ 35 years (AOR 2.77: 95% CI 1.02-7.52), general anesthesia (AOR 4.05: 95% CI 1.37-11.95) and classic incision (AOR 6.01: 95% CI 1.51-23.98). One in 25 women who gave birth during cesarean section experienced severe postpartum hemorrhage. Considering appropriate uterotonic agents and less invasive hemostatic interventions for high-risk mothers would help to decrease its overall rate and related morbidity.

Spontaneous Hemoperitoneum in Pregnancy and Endometriosis: A New Challenge in a Known Disease

Importance

Spontaneous hemoperitoneum in pregnancy (SHiP) is a rare life-threatening event previously associated with endometriosis. Although pregnancy is thought to improve the symptoms of endometriosis, abrupt intraperitoneal bleeding can occur, jeopardizing both maternal and fetal outcomes.

Objective

The aim of this study was to review the published information regarding SHiP pathophysiology, presentation, diagnosis, and management in a flowchart approach.

Evidence Acquisition

A descriptive review of published articles in the English-language was carried out.

Results

SHiP most commonly presents in the second half of pregnancy with a combination of abdominal pain, hypovolemia, a decline in hemoglobin level, and fetal distress. Nonspecific gastrointestinal symptoms are not uncommon. Surgical management is suitable in most scenarios and avoids complications such as recurrent bleeding and infected hematoma. Maternal outcome has improved greatly, whereas perinatal mortality remained unchanged. In addition to physical strain, SHiP was reported to have a psychosocial sequela.

Conclusions and Relevance

A high index of suspicion is required when patients present with acute abdominal pain and signs of hypovolemia. Early use of sonography contributes to narrowing down the diagnosis. Health care providers should be familiar with the SHiP diagnosis because early identification is crucial when attempting to safeguard maternal and fetal outcomes. Maternal and fetal requirements are often contradictory, creating a greater challenge in decision-making and treatment. A multidisciplinary team approach should coordinate the treatment, whenever a SHiP diagnosis is suspected.

Women and partners' experience of major postpartum haemorrhage: a qualitative study

OBJECTIVE

To examine women and their partners' experience of major postpartum haemorrhage (PPH).

DESIGN

A qualitative interview study.

SETTING

Two Labour and Delivery Units in Denmark.

POPULATION

Women who experienced major PPH (≥1 litre within 2 hours after vaginal birth).

METHODS

Semi-structured interviews were conducted with 15 women and nine partners (nine joint interviews, six individual interviews). Interviews were analysed using thematic analysis.

MAIN OUTCOME MEASURES

A qualitative description of women and their partners' experiences.

RESULTS

Three major themes were identified. (1) 'From birth to emergency' included factors that increased concern in women and their partners, such as 'incomprehensible' medical terminology, a tense atmosphere, and alarm call. Transfer to the operating theatre was experienced as the most devastating part of major PPH. (2) 'Feeling safe during an emergency' described factors that supported the women and their partners' management of the situation such as brief explanations from a few healthcare professionals and reassurance that the healthcare professionals were in control of the situation. The pain was experienced as severe, but acceptable. (3) 'Family unity challenged' described how family bonding was supported by positioning the partner at the head of the bed and by keeping the baby on the woman's chest.

CONCLUSIONS

Several factors such as small gestures from healthcare professionals and appropriate organisation of the PPH can make a difference to the woman and her partner's experience of major PPH. Particularly, efforts that support family bonding are greatly valued by women and their partners.

Development and evaluation of a wearable peripheral vascular compensation sensor in a swine model of hemorrhage

Postpartum hemorrhage (PPH) is both the leading and most preventable cause of maternal mortality. PPH is currently diagnosed through visual estimation of blood loss or vital sign analysis of shock index (ratio of heart rate to systolic blood pressure). Visual assessment underestimates blood loss, particularly in the setting of internal bleeding, and compensatory mechanisms stabilize hemodynamics until hemorrhage is massive, beyond the point of pharmaceutical intervention. Quantitative monitoring of hemorrhage-induced compensatory processes, such as the constriction of peripheral vessels to shunt blood to the central organs, may provide an early alert for PPH. To this end, we developed a low-cost, wearable optical device that continuously monitors peripheral perfusion via laser speckle flow index (LSFI) to detect hemorrhage-induced peripheral vasoconstriction. The device was first tested using flow phantoms across a range of physiologically relevant flow rates and demonstrated a linear response. Subsequent testing occurred in swine hemorrhage studies (n=6) by placing the device on the posterior side of the swine's front hock and withdrawing blood from the femoral vein at a constant rate. Resuscitation with intravenous crystalloids followed the induced hemorrhage. The mean LSFI vs. percent estimated blood volume loss had an average correlation coefficient of -0.95 during the hemorrhage phase and 0.79 during resuscitation, both of which were superior to the performance of the shock index. With continued development, this noninvasive, low-cost, and reusable device has global potential to provide an early alert of PPH when low-cost and accessible management strategies are most effective, helping to reduce maternal morbidity and mortality from this largely preventable problem.

Design of a postpartum hemorrhage and transfusion risk calculator

Background

Postpartum hemorrhage is the major cause of maternal deaths due to childbirth and also responsible for maternal morbidity.

Objectives

In this study we set out to look the incidence of postpartum hemorrhage in our population, to identify the most important risk factors for postpartum hemorrhage and thus develop a predictive risk calculator for postpartum hemorrhage and transfusion.

Study design

data was taken from patients who presented vaginal delivery or cesarean section from January 1 to December 31, 2016, the variables taken into account as risk factors were as follows: Gestational age, history of chronic or gestational hypertension, preeclampsia, previous abortions, parity, previous cesarean section, placenta previa, labor time, and postpartum hemorrhage as the event of interest. An objective quantification was performed on a weight scale in grams for the estimation of bleeding, considering postpartum hemorrhage those with >500 ml in vaginal delivery and >1000 ml of blood loss in cesarean section. Subsequently, a predictive risk calculator was developed using the Naïve Bayes algorithm.

Results

A success rate of 58% was obtained in the identification of patients at high risk of hemorrhage, and 36% for transfusion, with a sensitivity of 50.7% and specificity of 64.06%, identifying as risk factors for postpartum hemorrhage gestational age between 35 and 40 weeks, hypertension and preeclampsia, previous cesarean section, duration of labor <1 h or more than 10 h, placenta previa and previous history of postpartum hemorrhage.

Conclusion

A postpartum hemorrhage risk calculator has been designed, which due to its improved accuracy after incorporation of data becomes a useful tool that will require a larger study population to improve its performance in clinical practice and more similar studies to validate it.

Cost-effectiveness analysis of carbetocin for prevention of postpartum hemorrhage in a low-burden high-resource city of China

BACKGROUND

Postpartum hemorrhage (PPH) is a major cause of maternal morbidity, and oxytocin is the first-line uterotonic agent for PPH prevention. Clinical findings have reported carbetocin to reduce PPH risk without increasing risk of important side effects. Hong Kong is a low PPH burden and high-resource city in China. We aimed to examine the cost-effectiveness of PPH prevention with carbetocin from the perspective of Hong Kong public healthcare provider.

METHODS

A decision-analytic model was developed to simulate clinical and economic outcomes of carbetocin and oxytocin for PPH prevention in a hypothetical cohort of women at the third stage of labor following vaginal birth or Caesarean section (C-section). The model inputs were retrieved from literature and public data. Base-case analysis and sensitivity analysis were performed. The model time horizon was the postpartum hospitalization period. Primary model outcomes included PPH-related direct medical cost, PPH, hysterectomy, maternal death, and quality-adjusted life-year (QALY) loss.

RESULTS

In base-case analysis, carbetocin (versus oxytocin) reduced PPH-related cost (by USD29 per birth), PPH ≥500 mL and ≥1,500 mL (by 13.7 and 1.9 per 1,000 births), hysterectomy (by 0.15 per 1,000 births), maternal death (by 0.02 per 1,000 births), and saved 0.00059 QALY per birth. Relative risk of PPH ≥500 mL with carbetocin versus oxytocin, and proportion of child births by C-section were two influential parameters identified in deterministic sensitivity analysis. In probabilistic sensitivity analysis, carbetocin was accepted as cost-effective in >99.7% of the 10,000 Monte Carlo simulations at a willingness-to-pay threshold of zero USD/QALY.

CONCLUSION

PPH prevention with carbetocin appeared to reduce major unfavorable outcomes, and save cost and QALYs.

Is there a role for carbetocin in the prophylaxis of postpartum obstetric haemorrhage?

Postpartum haemorrhage is a common complication of pregnancy, most commonly due to uterine atony. Uterotonics have a vital role in preventing postpartum haemorrhage but the choice of the most effective agent with the fewest adverse effects is a subject of debate. Carbetocin, a synthetic analogue of oxytocin has been available in the UK since 2007 but is not currently widely used. It has a longer duration of action than oxytocin, which avoids the need for an infusion and as it is heat-stable it can be stored at room temperature. Current UK clinical guidelines, based on the results of older meta-analyses, do not recommend carbetocin as a first-line agent. A Cochrane review, published in 2018, ranked carbetocin in the top three drug regimens for preventing postpartum haemorrhage and an international consensus statement on uterotonic use for caesarean birth concluded that carbetocin may become the preferred drug for caesarean birth, by reducing the need for additional uterotonics. The higher cost of carbetocin when compared with oxytocin is a limiting factor, but the significant healthcare costs of a postpartum haemorrhage and the physiological impact of this event suggests it a reasonable alternative to consider, especially if ergometrine is contraindicated or in those who are undergoing a caesarean birth or are at high risk of bleeding.

Postpartum hemorrhage and postpartum depressive symptoms: A retrospective cohort study

BACKGROUND

Many psychological and obstetrical factors contribute to the development of postpartum depression. However, little is known about how postpartum hemorrhage (PPH) influences postpartum depressive symptoms. This study explored the relationship between PPH and postpartum depressive symptoms in the Chinese population.

METHODS

A retrospective cohort study was conducted at the Baoan Maternal and Child Health Hospital in Shenzhen, China, from January 2016 to June 2020. The Edinburgh Postnatal Depression Scale was used to assess postpartum depressive symptoms. A multivariate logistic regression model was used to estimate the odds ratios (ORs) with 95% confidence intervals (95% CIs) between PPH and risk of postpartum depressive symptoms.

RESULTS

Of the 7734 respondents, 293 (3.8%) and 7441 were in the PPH and control groups, respectively. Puerperal women with PPH were more likely to screen positive for postpartum depressive symptoms than those without PPH (16.4% vs. 11.7%, p = .016). Adjusting for other covariates, women with PPH still had higher risk of postpartum depressive symptoms (OR = 1.68, 95% CI: 1.16-2.42). Stratification analyses revealed no interaction between PPH and maternal age, prepregnancy body mass index, mode of delivery, and fetal sex in developing depressive symptoms (p for interaction > .05).

CONCLUSIONS

PPH may increase the risk of postpartum depressive symptoms. Therefore, women with PPH should be actively screened for depressive symptoms in the immediate postpartum period.

Posttraumatic Stress Disorder Symptoms 2 Months After Vaginal Delivery

OBJECTIVE

To assess the prevalence of posttraumatic stress disorder (PTSD) symptoms and identify characteristics associated with it 2 months after singleton vaginal delivery at or near term.

METHODS

We conducted an ancillary cohort study of the TRAAP (TRAnexamic Acid for Preventing postpartum hemorrhage after vaginal delivery) randomized controlled trial in 15 French hospitals in 2015-2016. Women who had singleton vaginal delivery after 35 weeks of gestation were enrolled. After randomization, characteristics of labor and delivery were prospectively collected and paid special attention to postpartum blood loss. Posttraumatic stress disorder profile and provisional diagnosis were assessed 2 months after childbirth by two self-administered questionnaires: the IES-R (Impact of Event Scale-Revised) and the TES (Traumatic Event Scale). Associations between potential risk factors and PTSD symptoms were analyzed by multivariable logistic or linear regression modeling, depending on the type of dependent variable.

RESULTS

Questionnaires were returned by 2,740 of 3,891 women for the IES-R and 2,785 of 3,891 women for the TES (70.4% and 71.6% response rate). The prevalence of PTSD symptoms was 4.9% (95% CI 4.1-5.8%; 137/2,785) with the TES, and the prevalence of PTSD provisional diagnosis was 1.6% (95% CI 1.2-2.1%; 44/2,740), with the IES-R and 0.4% (95% CI 0.2-0.8%; 9/2,080) with the TES. Characteristics associated with a higher risk of PTSD in multivariable analysis were vulnerability factors - notably migrant status and history of psychiatric disorder (adjusted odds ratio [aOR] 2.7 95% CI 1.4-5.2) - and obstetric factors - notably induced labor (aOR 1.5 95% CI 1.0-2.2), being labor longer than 6 hours (aOR 1.7 95% CI 1.1-2.5), postpartum hemorrhage of 1,000 mL or more (aOR 2.0 95% CI 1.0-4.2), and bad memories of delivery at day 2 postpartum (aOR 4.5 95% CI 2.4-8.3) as assessed with the IES-R. Results were similar with the TES.

CONCLUSION

Approximately 1 of 20 women with vaginal delivery have PTSD symptoms at 2 months postpartum. History of psychiatric disorder, postpartum hemorrhage, and bad memories of deliveries at day 2 were the main factors associated with a PTSD profile.

Cost-effectiveness analysis of carbetocin versus oxytocin for the prevention of postpartum hemorrhage following vaginal birth in the United Kingdom

AIMS

To assess the cost-effectiveness of carbetocin versus oxytocin for the prevention of postpartum hemorrhage (PPH) following vaginal birth from the perspective of the UK National Health Service (NHS).

MATERIALS AND METHODS

A decision tree model was designed to analyze the cost per PPH event avoided associated with utilizing carbetocin versus oxytocin for prophylactic treatment of PPH in women following vaginal birth from a UK perspective. It modelled the potential for women to require an additional uterotonic after prophylaxis, and to still experience a PPH event and receive associated treatment. Inpatient recovery and follow-up periods post-PPH were also included in the model. Costs associated with drug acquisition and administration, PPH management (i.e. additional staffing and possible operating theater and high dependency unit utilization), inpatient hospitalization, and follow-up visits were all considered. Adverse event management costs were not included. Resource utilization varied depending on the severity of the PPH event (as defined by the amount of blood lost). PPH events avoided were estimated. In an exploratory analysis, quality adjusted life years (QALYs) were estimated as well.

RESULTS

In the deterministic base case, costs were £55 lower and PPH events were 0.0342 lower per woman with carbetocin use compared to oxytocin use. Across the cohort of 100 women the reduction in PPH events led to the largest cost savings (£4,233 saved) out of all cost categories, with total cost savings of £5,495. Carbetocin utilization amongst the entire cohort led to 3.42 avoided PPH events compared to oxytocin utilization, comprised of 3.03 fewer mild/moderate PPH events and 0.39 fewer severe PPH events. Carbetocin utilization led to 0.0001 additional QALYs per woman.

CONCLUSION

Carbetocin utilization leads to lower prophylactic treatment costs and less PPH events versus oxytocin when utilized for the prevention of PPH following vaginal birth in the UK.

A study of the healthcare resource use for the management of postpartum haemorrhage in France, Italy, the Netherlands, and the UK

OBJECTIVE

Postpartum haemorrhage (PPH) complicates approximately 5% of births worldwide and is a leading direct cause of maternal death. Rates of PPH are increasing in many developed countries, particularly PPH related to uterine atony. There is a lack of published up-to-date information about healthcare resource use associated with management of PPH following vaginal birth. The objective of this study was to describe healthcare resource use for the management of minor PPH (blood loss 500-1,000 ml) and major PPH (blood loss > 1,000 ml) compared to uncomplicated birth (no PPH) following hospital vaginal birth in France, Italy, the Netherlands, and the UK.

STUDY DESIGN

In-depth interviews with two midwives from each participating country were conducted to establish differences in resource use for the management of minor PPH, major PPH, and uncomplicated birth. A web-survey was then developed and one obstetrician per participating country reviewed the survey. In total, 100 midwives (25 per country) completed the survey. Results were discussed at a multi-professional consensus meeting of midwives and obstetricians/gynaecologists (n = 6).

RESULTS AND CONCLUSIONS

Midwives participating in the survey estimated that 80% of women receive Active Management of the Third Stage of Labour (AMTSL) and 93% of participants specified that uterotonics would routinely be used during AMTSL. Most participants (84%) reported that blood loss is routinely measured in their hospital, using a combination of methods. PPH is associated with increased healthcare resource use, including administration of additional uterotonics and use of additional medical interventions, such as urinary catheter, intravenous fluids, and possible requirement for surgery. The number of nurses, obstetricians/gynaecologists, and anaesthetists involved in the management of PPH increases with the occurrence and severity of PPH, as well as the proportion of healthcare personnel providing continuous care. Women may spend an additional 24 h in hospital following major PPH compared to uncomplicated birth. The results of this study highlight the burden of PPH management on healthcare resources. To reduce costs associated with PPH, prevention is the most effective strategy and can be enhanced with the use of an effective uterotonic as part of the active management of the third stage of labour.

The association between postpartum hemorrhage and postpartum depression: A Swedish national register-based study

Background

Postpartum hemorrhage is an important cause of maternal death and morbidity. However, it is unclear whether women who experience postpartum hemorrhage are at an increased risk of postpartum depression.

Objectives

To examine whether postpartum hemorrhage is associated with postpartum depression.

Methods

We conducted a national register-based cohort study of 486,476 Swedish-born women who had a singleton livebirth between 2007 and 2014. We excluded women with pre-existing depression or who filled a prescription for an antidepressant before childbirth. We classified postpartum depression up to 12 months after giving birth by the presence of an International Classification of Diseases, version 10 (ICD-10) diagnosis code for depression or a filled outpatient prescription for an antidepressant. We used Cox proportional hazard models, adjusting for maternal sociodemographic and obstetric factors.

Results

Postpartum depression was identified in 2.0% (630/31,663) of women with postpartum hemorrhage and 1.9% (8601/455,059) of women without postpartum hemorrhage. In our unadjusted analysis, postpartum hemorrhage was not associated with postpartum depression (unadjusted hazard ratio (HR) = 1.06, 95% confidence interval (CI) 0.97–1.15). After adjusting for maternal age, parity, education, cohabitation status, maternal smoking status, and early pregnancy maternal BMI, gestational age, and birthweight, the association did not appreciably change, with confidence intervals overlapping the null (adjusted HR = 1.08, 95% CI 0.99, 1.17).

Conclusions

Within a population-based cohort of singleton women in Sweden with no prior history of depression, postpartum hemorrhage was not associated with postpartum depression.

European principles of care for women and girls with inherited bleeding disorders

INTRODUCTION

Despite increasing awareness of issues faced by women and girls with inherited BDs (WGBD), standards of care are lacking, with disparities in diagnosis and treatment for WGBD across Europe. We aimed to develop practical principles of care (PoC) to promote standardization of care for WGBD within European Haemophilia Treatment and Comprehensive Care Centres (HTC/CCCs).

METHODS

The co-creation process, supported by the European Association for Haemophilia and Allied Disorders, consisted of four multidisciplinary meetings with health care providers (HCPs) experienced in WGBD care, and European Haemophilia Consortium representatives, combined with broad patient and HCP consultations in the European haemophilia community. Relevant medical societies outside Europe were contacted for confirmation.

RESULTS

We developed ten PoC for WGBD, stressing the importance and benefits of a centralized, multidisciplinary, comprehensive, family-centred approach to support and manage WGBD during all life stages. These PoC emphasise the right to equitable access and quality of care for all people with BDs, irrespective of gender. Multiple medical societies outside Europe also confirmed their support for endorsement.

CONCLUSIONS

Ten PoC for WGBD evolved from an iterative process among stakeholders, supported by relevant medical societies worldwide. These PoC can serve as a benchmark for diagnosis and comprehensive multidisciplinary management of WGBD, and improve awareness of their unique challenges. They offer a framework to guide HTC/CCCs in providing equitable care for all WGBD, both in their own services and in other healthcare settings. Implementation of these principles aims to positively impact the health, wellbeing and quality of life for WGBD.

Paternal and maternal long-term psychological outcomes after uterine artery embolization for severe post-partum hemorrhage

This study intend to compare the long-term psychological impact (depression, post-traumatic stress disorder) on both partners between patients that underwent uterine artery embolization (UAE) for post-partum hemorrhage (PPH) and uneventful deliveries. Women who experienced severe PPH treated by UAE in our institution between 2003 and 2013 were identified in our obstetrical database. These cases were matched to controls with uneventful deliveries. Matching criteria were maternal age, parity, ethnicity, year of delivery, birthweight, gestational age and mode of delivery. Patients and their partners completed validated questionnaires measuring post-traumatic stress (TSQ), as well as depression symptoms (MINI). A total of 63 cases of PPH and 189 matched controls (1:3) participated in a study exploring gynecological and obstetrical outcomes. With a mean of 8 years post-index delivery, patients after PPH showed increased risk of depression (p = 0.015) and post-traumatic stress disorder (22.2% versus 4.8%, p < 0.005) compared to controls. PPH remains strongly associated with post-traumatic stress disorder, even after adjustment for depression (adjusted odds ratio 5.1; 95% confidence intervals 1.5–17.5). Similarly, partners of patients with PPH showed a propensity to depression (p = 0.029) and post-traumatic stress disorder (11.5% versus 1.5%, p = 0.019). In conclusion, both women and their partners are at increased risk of long-term psychological adverse outcomes after PPH. Couples may benefit from psychological support.

Severe psychological impact and impaired quality of life after a spontaneous haemoperitoneum in pregnancy in women with endometriosis and their partners

Background

Spontaneous Haemoperitoneum in Pregnancy (SHiP) is a rare, but life-threatening complication of pregnancy that occurs predominantly in the third trimester of pregnancy and is associated with adverse pregnancy outcomes. Recently the largest case series in literature was published describing 11 Dutch cases of SHiP in women with endometriosis.

Purpose

To investigate experiences, psychological impact, and quality of life after SHiP.

Methods

A mixed-methods study was performed in women with a history of SHiP and their partners, including all known cases in the Netherlands between 2007 to 2015. Semi-structured in-depth interviews were organized between 2016 and 2017 and analysed thematically with a framework approach. Participants were asked to complete questionnaires investigating the impact of the event (Impact of Event Scale) and Quality of Life (RAND-36).

Results

Out of a total of 11 known cases, 7 women agreed for be individually interviewed. From these, all women described a freeze response at the moment of SHiP, combined with either an anxious reaction or a survival mode mind-set. All women received psychological help after SHiP. Still, the feeling of not being heard by the medical staff was present in all women. Other themes such as postpartum period, bonding with their child, effect on daily life, reviving the event, and future pregnancies were also identified in the interviews. In regard to their partners, 3 were interviewed, hence no saturation was achieved. Finally, the questionnaires showed lower Quality of Life and an impact score of ≥ 8/10.

Conclusion

SHiP had a profound impact on women and their partners. Dedicated psychological help should be offered to all women after experiencing SHiP.

The risk of postpartum hemorrhage when lowering the oxytocin dose in planned cesarean section, a pilot study

OBJECTIVES

Oxytocin is the drug of choice in preventing postpartum hemorrhage (PPH). The aim was to compare the peroperative- and total blood loss within two hours and PPH after planned cesarean section (CS) when receiving 2.5 IU vs 5.0 IU of oxytocin in different risk groups for PPH.

STUDY DESIGN

A pilot study including 927 women undergoing planned CS where women receiving 2.5 IU of oxytocin were compared to women receiving 5.0 IU of oxytocin.

MAIN OUTCOME MEASURES

Data comparing peroperative blood loss, total blood loss within two hours and PPH were analyzed.

RESULTS

The women receiving 2.5 IU of oxytocin had a slightly higher peroperative blood loss, compared to the 5.0 IU group (476 ml vs 426 ml, p = 0.029). The total blood loss two hours after surgery showed no significant difference between the groups (626 ml vs 595 ml, p = 0.230). In the 2.5 IU group 13% had a blood loss ≥ 1000 ml vs 10% in the 5 IU group (aOR 1.64, 95% CI = 1.05-2.56). When the women considered to be at high risk for postpartum hemorrhage were excluded, we found no difference in the likelihood for postpartum hemorrhage between the groups (aOR 1.13, 95% CI = 0.64-1.99).

CONCLUSIONS

Women undergoing planned CS and receiving 2.5 IU of oxytocin had a slightly higher risk for postpartum hemorrhage in this study. However, a lower dose of 2.5 IU of oxytocin seems to be a safe option in planned CS for women without known risk factors for postpartum hemorrhage, but further research is needed to confirm these findings.

Haematological parameters associated with postpartum haemorrhage after vaginal delivery: Results from a French cohort study

BACKGROUND

Immediate postpartum haemorrhage (PPH) is a major, feared and often unpredictable issue. Besides many clinical risk factors, some biological parameters could also be predictive of PPH.

OBJECTIVE

To study simple and easily accessible haematological parameters as potential risk factors for PPH after vaginal delivery.

METHODS

All women who had a vaginal delivery between April 1, 2013 and May 29, 2015 in the maternity ward of Brest University Hospital (France) were included, after oral informed consent obtained. Clinical data were collected by obstetricians or midwives during antenatal care visits, labour and delivery, and recorded by trained research assistants. Haematological variables, including immature platelet fraction, were measured from a blood sample systematically collected at the entrance in the delivery room. PPH, measured with a graduated collector bag, was defined as blood loss of at least 500 ml.

RESULTS

2742 women were included. PPH occurred in 141 (5%) women. Seven clinical factors were independently associated with PPH: pre-eclampsia (OR 5.85, 95%CI 2.02, 16.90), multiple pregnancy (OR 3.28, 95%CI 1.21, 8.91), assisted reproduction (OR 2.75, 95%CI 1.45, 5.20), antepartum bleeding (OR 2.15, 95%CI 1.24,3.73), post-term delivery (OR 1.93, 95%CI 1.17, 3.17), obesity (OR 2.95, 95%CI 1.76, 4.93) and episiotomy (OR 2.51, 95%CI 1.63, 3.74). Three haematological factors were additionally identified as independent risk factors for PPH: platelets < 150 Giga/L (OR 2.98, 95%CI 1.63, 5.46), fibrinogen < 4.5 g/l (OR 1.86, 95%CI 1.21, 2.87) and APTT ratio ≥ 1.1 (OR 2.16, 95%CI 1.31, 3.57). Immature platelet fraction was not associated with PPH.

CONCLUSION

Besides classical clinical risk factors, this study identifies simple haematological parameters as risk factors for PPH.

Reduction in massive postpartum haemorrhage and red blood cell transfusion during a national quality improvement project, Obstetric Bleeding Strategy for Wales, OBS Cymru: an observational study

Background

Postpartum haemorrhage (PPH) is a major cause of maternal morbidity and mortality and its incidence is increasing in many countries despite management guidelines. A national quality improvement programme called the Obstetric Bleeding Strategy for Wales (OBS Cymru) was introduced in all obstetric units in Wales. The aim was to reduce moderate PPH (1000 mL) progressing to massive PPH (> 2500 mL) and the need for red cell transfusion.

Methods

A PPH care bundle was introduced into all 12 obstetric units in Wales included all women giving birth in 2017 and 2018 (n = 61,094). The care bundle prompted: universal risk assessment, quantitative measurement of blood loss after all deliveries (as opposed to visual estimation), structured escalation to senior clinicians and point-of-care viscoelastometric-guided early fibrinogen replacement. Data were submitted by each obstetric unit to a national database. Outcome measures were incidence of massive PPH (> 2500 mL) and red cell transfusion. Analysis was performed using linear regression of the all Wales monthly data.

Results

Uptake of the intervention was good: quantitative blood loss measurement and risk assessment increased to 98.1 and 64.5% of all PPH > 1000 mL, whilst ROTEM use for PPH > 1500 mL increased to 68.2%. Massive PPH decreased by 1.10 (95% CI 0.28 to 1.92) per 1000 maternities per year (P = 0.011). Fewer women progressed from moderate to massive PPH in the last 6 months, 74/1490 (5.0%), than in the first 6 months, 97/1386 (7.0%), (P = 0.021). Units of red cells transfused decreased by 7.4 (95% CI 1.6 to 13.2) per 1000 maternities per year (P = 0.015). Red cells were transfused to 350/15204 (2.3%) and 268/15150 (1.8%) (P = 0.001) in the first and last 6 months, respectively. There was no increase in the number of women with lowest haemoglobin below 80 g/L during this time period. Infusions of fresh frozen plasma fell and there was no increase in the number of women with haemostatic impairment.

Conclusions

The OBS Cymru care bundle was feasible to implement and associated with progressive, clinically significant improvements in outcomes for PPH across Wales. It is applicable across obstetric units of widely varying size, complexity and staff mixes.

Postpartum haemorrhage and risk of mental ill health: A population-based longitudinal study using linked primary and secondary care databases

There is a gap in the literature investigating the impact of obstetric complications on subsequent mental ill health outcomes. The aim of this study was to establish the association between post-partum haemorrhage (PPH) and mental ill health. We conducted a retrospective open cohort study utilizing linked primary care (The Health Improvement Network (THIN)) and English secondary care (Hospital Episode Statistics (HES)) databases, from January 1, 1990 to January 31, 2018. A total of 42,327 women were included: 14,109 of them were exposed to PPH during the study period and 28,218 unexposed controls were matched for age and date of delivery. Hazard ratios (HRs) for mental illness among women with and without exposure to PPH were estimated after controlling for covariates. Women who had had PPH were at an increased risk of developing postnatal depression (adjusted HR: 1·10, 95%CI: 1·01-1·21) and post-traumatic stress disorder (PTSD) (adjusted HR: 1·17, 95%CI: 0·73-1·89) compared to women unexposed to PPH. When restricting the follow-up to the first year after childbirth, the adjusted HR for PTSD was 3·44 (95% CI 1·31-9·03). No increase in the overall risk was observed for other mental illnesses, including depression (adjusted HR: 0·94, 95%CI: 0·87-1·01), severe mental illness (adjusted HR: 0·65, 95%CI: 0·40-1·08, p = 0·239) and anxiety (adjusted HR: 0·99, 95%CI: 0·90-1·09). PPH is associated with a significant increase in the risk of developing postnatal depression and PTSD in the first year after delivery. Active monitoring for mental illness should form an integral part of the follow-up in women who suffered a PPH.

Peripartum Predictors of the Risk of Postpartum Depressive Disorder: Results of a Case-Control Study

Background: The study aimed at the identification of the risk factors present during delivery, which might be present in prophylactic programs concerning postpartum mood disorders. Material and Method: This was a retrospective comparative study. The study material included data retrieved from the medical records of patients hospitalized in the Teaching Department of Gynecology and Obstetrics of Professor Orłowski Hospital in Warsaw, in the years 2010–2017. The EPDS data of 604 patients were analyzed. The study group included 75 women who obtained at least 12 points in the EPDS and the control group was made up of 75 women who obtained no more than 5 points in the EPDS. Results: The women in whom we noted an increased risk of developing mood disorders had blood loss >1000 mL and had a significantly longer stage II and III of labor than the control group. Other risk factors were cesarean section, vaginal delivery with the curettage of the uterine cavity, slightly lower APGAR scores (0.4 pts), and lower birth weight (approximately 350 g) of the child. Women at a low risk of postpartum mood disorders more commonly underwent episiotomy during delivery (76%). Conclusions: Increased supervision and support should be offered to women who experienced the above-mentioned risk factors.

Prevention of postpartum hemorrhage

Postpartum hemorrhage is a leading cause of severe maternal morbidity and mortality worldwide and the United States. While the rates of maternal mortality attributable to hemorrhage are declining, severe maternal morbidity continues to be a growing problem. Efforts in recent years to more appropriately identify patients at risk, define significant hemorrhage, quantify blood loss, and standardize approaches to care in pregnancy and postpartum have led to an increasing preventability of PPH. We aim to review the most current recommendation for the prevention and effective management of obstetric hemorrhage.

Conservative approach: Intentional retention of the placenta

Intentional retention of the placenta (IRP), or 'conservative' treatment or management, entails opening the uterus, delivering the baby, tying and cutting the umbilical cord at its placental insertion site, leaving the placenta in the uterus and waiting for its complete spontaneous resorption in women with placenta accreta spectrum (PAS). The uterine preservation rate with this approach is about 78%, and severe maternal morbidity about 6%; these rates are respectively lower and higher in subgroups of women with placenta percreta. IRP has become a recommended option for women with PAS reluctant to undergo caesarean-hysterectomy and wanting to preserve their fertility, after appropriate information about the uterine preservation rate, but also the risk of a subsequent emergency hysterectomy due to unpredictable haemorrhage and/or infection, and the need for follow-up with regular visits for several months. Some authorities also recommend IRP when hysterectomy is at very high risk of surgical complications.

Maternal morbidity and mortality due to placenta accreta spectrum disorders

Placenta accreta spectrum (PAS) disorders are an increasing health problem in many parts of the world. They are an important risk factor for adverse maternal outcomes related to delivery, with a reported 18-fold increase in maternal morbidity. Profuse haemorrhage after attempting to remove the placenta is the most frequent complication and can lead to major maternal morbidity and ultimately to maternal death. Morbidity can also arise from the multiple procedures required to treat PAS disorders. Intensive care unit admission, mechanical ventilation, infection, and prolonged hospitalization are common in these patients. Long-term complications related to infertility and psychological disturbances can also occur and may have a strong and long-lasting impact on women's health. Antenatal diagnosis allows for appropriate scheduling of delivery and referral to a specialized centre and has been shown to reduce maternal morbidity and mortality.

Mechanical and surgical interventions for treating primary postpartum haemorrhage

BACKGROUND

Primary postpartum haemorrhage (PPH) is commonly defined as bleeding from the genital tract of 500 mL or more within 24 hours of birth. It is one of the most common causes of maternal mortality worldwide and causes significant physical and psychological morbidity. An earlier Cochrane Review considering any treatments for the management of primary PPH, has been split into separate reviews. This review considers treatment with mechanical and surgical interventions.

OBJECTIVES

To determine the effectiveness and safety of mechanical and surgical interventions used for the treatment of primary PPH.

SEARCH METHODS

We searched Cochrane Pregnancy and Childbirth's Trials Register, ClinicalTrials.gov, the WHO International Clinical Trials Registry Platform (ICTRP) (26 July 2019) and reference lists of retrieved studies.

SELECTION CRITERIA

Randomised controlled trials (RCTs) of mechanical/surgical methods for the treatment of primary PPH compared with standard care or another mechanical/surgical method. Interventions could include uterine packing, intrauterine balloon insertion, artery ligation/embolism, or uterine compression (either with sutures or manually). We included studies reported in abstract form if there was sufficient information to permit risk of bias assessment. Trials using a cluster-RCT design were eligible for inclusion, but quasi-RCTs or cross-over studies were not.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed studies for inclusion and risk of bias, independently extracted data and checked data for accuracy. We used GRADE to assess the certainty of the evidence.

MAIN RESULTS

We included nine small trials (944 women) conducted in Pakistan, Turkey, Thailand, Egypt (four trials), Saudi Arabia, Benin and Mali. Overall, included trials were at an unclear risk of bias. Due to substantial differences between the studies, it was not possible to combine any trials in meta-analysis. Many of this review's important outcomes were not reported. GRADE assessments ranged from very low to low, with the majority of outcome results rated as very low certainty. Downgrading decisions were mainly based on study design limitations and imprecision; one study was also downgraded for indirectness. External uterine compression versus normal care (1 trial, 64 women) Very low-certainty evidence means that we are unclear about the effect on blood transfusion (risk ratio (RR) 2.33, 95% confidence interval (CI) 0.66 to 8.23). Uterine arterial embolisation versus surgical devascularisation plus B-Lynch (1 trial, 23 women) The available evidence for hysterectomy to control bleeding (RR 0.73, 95% CI 0.15 to 3.57) is unclear due to very low-certainty evidence. The available evidence for intervention side effects is also unclear because the evidence was very low certainty (RR 1.09; 95% CI 0.08 to 15.41). Intrauterine Tamponade Studies included various methods of intrauterine tamponade: the commercial Bakri balloon, a fluid-filled condom-loaded latex catheter ('condom catheter'), an air-filled latex balloon-loaded catheter ('latex balloon catheter'), or traditional packing with gauze. Balloon tamponade versus normal care (2 trials, 356 women) One study(116 women) used the condom catheter. This study found that it may increase blood loss of 1000 mL or more (RR 1.52, 95% CI 1.15 to 2.00; 113 women), very low-certainty evidence. For other outcomes the results are unclear and graded as very low-certainty evidence: mortality due to bleeding (RR 6.21, 95% CI 0.77 to 49.98); hysterectomy to control bleeding (RR 4.14, 95% CI 0.48 to 35.93); total blood transfusion (RR 1.49, 95% CI 0.88 to 2.51); and side effects. A second study of 240 women used the latex balloon catheter together with cervical cerclage. Very low-certainty evidence means we are unclear about the effect on hysterectomy (RR 0.14, 95% CI 0.01 to 2.74) and additional surgical interventions to control bleeding (RR 0.20, 95% CI 0.01 to 4.12). Bakri balloon tamponade versus haemostatic square suturing of the uterus (1 trial, 13 women) In this small trial there was no mortality due to bleeding, serious maternal morbidity or side effects of the intervention, and the results are unclear for blood transfusion (RR 0.57, 95% CI 0.14 to 2.36; very low certainty). Bakri balloon tamponade may reduce mean 'intraoperative' blood loss (mean difference (MD) -426 mL, 95% CI -631.28 to -220.72), very low-certainty evidence. Comparison of intrauterine tamponade methods (3 trials, 328 women) One study (66 women) compared the Bakri balloon and the condom catheter, but it was uncertain whether the Bakri balloon reduces the risk of hysterectomy to control bleeding due to very low-certainty evidence (RR 0.50, 95% CI 0.05 to 5.25). Very low-certainty evidence also means we are unclear about the results for the risk of blood transfusion (RR 0.97, 95% CI 0.88 to 1.06). A second study (50 women) compared Bakri balloon, with and without a traction stitch. Very low-certainty evidence means we are unclear about the results for hysterectomy to control bleeding (RR 0.20, 95% CI 0.01 to 3.97). A third study (212 women) compared the condom catheter to gauze packing and found that it may reduce fever (RR 0.47, 95% CI 0.38 to 0.59), but again the evidence was very low certainty. Modified B-Lynch compression suture versus standard B-Lynch compression suture (1 trial, 160 women) Low-certainty evidence suggests that a modified B-Lynch compression suture may reduce the risk of hysterectomy to control bleeding (RR 0.33, 95% CI 0.11 to 0.99) and postoperative blood loss (MD -244.00 mL, 95% CI -295.25 to -192.75).

AUTHORS' CONCLUSIONS

There is currently insufficient evidence from RCTs to determine the relative effectiveness and safety of mechanical and surgical interventions for treating primary PPH. High-quality randomised trials are urgently needed, and new emergency consent pathways should facilitate recruitment. The finding that intrauterine tamponade may increase total blood loss > 1000 mL suggests that introducing condom-balloon tamponade into low-resource settings on its own without multi-system quality improvement does not reduce PPH deaths or morbidity. The suggestion that modified B-Lynch suture may be superior to the original requires further research before the revised technique is adopted. In high-resource settings, uterine artery embolisation has become popular as the equipment and skills become more widely available. However, there is little randomised trial evidence regarding efficacy and this requires further research. We urge new trial authors to adopt PPH core outcomes to facilitate consistency between primary studies and subsequent meta-analysis.

Major obstetric haemorrhage in Metro East, Cape Town, South Africa: a population-based cohort study using the maternal near-miss approach

Background

Major obstetric haemorrhage is a leading cause of maternal mortality and accounts for one-third of maternal deaths in of Africa. This study aimed to assess the population-based incidence, causes, management and outcomes of major obstetric haemorrhage and risk factors associated with poor maternal outcome.

Methods

Women with major obstetric haemorrhage who met the WHO maternal near-miss criteria or died in the Metro East region, Cape Town, South Africa, were evaluated from November 2014–November 2015. Major obstetric haemorrhage was defined as haemorrhage in pregnancies of at least 20 weeks’ gestation or occurring up to 42 days after birth, and leading to hysterectomy, hypovolaemic shock or blood transfusion of ≥5 units of Packed Red Blood Cells. A logistic regression model was used to analyse associations with poor outcome, defined as major obstetric haemorrhage leading to massive transfusion of ≥8 units of packed red blood cells, hysterectomy or death.

Results

The incidence of major obstetric haemorrhage was 3/1000 births, and the incidence of massive transfusion was 4/10.000 births in the Metro East region (32.862 births occurred during the studied time period). Leading causes of haemorrhage were placental abruption 45/119 (37.8%), complications of caesarean section 29/119 (24.4%) and uterine atony 13/119 (10.9%). Therapeutic oxytocin was administered in 98/119 (82.4%) women and hysterectomy performed in 33/119 (27.7%). The median numbers of packed red blood cells and units of Fresh Frozen Plasma transfused were 6 (interquartile range 4–7) and 3 (interquartile range 2–4), ratio 1.7:1. Caesarean section was independently associated with poor maternal outcome: adjusted OR 4.01 [95% CI 1.58, 10.14].

Conclusions

Assessment of major obstetric haemorrhage using the Maternal Near Miss approach revealed that placental abruption and complications of caesarean section were the major causes of major obstetric haemorrhage. Caesarean section was associated with poor outcome.

Prevalence of maternal psychological disorders after immediate postpartum haemorrhage: a repeated cross-sectional study - the PSYCHE* study protoco

INTRODUCTION

The main objective of this study is to assess the prevalence of depression at 2, 6 and 12 months postpartum in women who have had an immediate postpartum haemorrhage (PPH) (blood loss ≥500 mL within 24 hours of delivery). The secondary objectives are to assess the prevalence of anxiety and post-traumatic stress disorder among these women and to evaluate the prevalence of psychological disorders according to the severity of the PPH.

METHODS AND ANALYSIS

This repeated, cross-sectional, single-centre study will take place at the Clermont-Ferrand University Hospital (France). The population will comprise a cohort of women giving birth at a term ≥22 weeks of gestation.For each woman with a PPH (exposed), two women without PPH (unexposed) will be included: the women who give birth immediately before and immediately after her. The PPH will be managed according to French guidelines. The principal endpoint is the prevalence of depression, measured by the Edinburgh Postnatal Depression Scale (EPDS). The intervention will consist of four surveys including various self-completed questionnaires: the first during the immediate postpartum (Post-Delivery Perceived Stress Inventory (PDPSI), Spielberger'sState-Trait Anxiety Inventory (STAI)-Y-A and Y-B and Mini-International Neuropsychiatric Interview (M.I.N.I.) 5.0.0), then at 2 months (EPDS, STAI-Y-A, Generalised Anxiety Disorder (GAD-7) and Revised Impact of Event Scale (IES-R)), and finally at 6 months and 1 year postpartum (EPDS, STAI-Y-A, GAD-7, M.I.N.I. 5.0.0 and IES-R). The study will include 1542 women - 514 with PPH.

ETHICS AND DISSEMINATION

The institutional review board (IRB) approved the study on 14 February 2017 (IRB Sud Est VI: N°AU1243).Results will be reported in peer-reviewed journals and at scientific meetings. Findings from the study will be useful for individualising medical follow-up after childbirth, especially for woman who experienced a PPH, but also more generally in increasing birth professionals' awareness of effects of trauma. The evidence obtained might also lead to modifying practices and including this recommendation in French guidelines on PPH.

Is there an association between postpartum hemorrhage, interventional radiology procedures, and psychological sequelae?

BACKGROUND

Postpartum hemorrhage (PPH) may cause post-traumatic psychological sequelae. Interventional radiology procedures (IRP) have been established in the management of PPH when conventional management fails. IRP is also used prophylactically in women who are at high risk for PPH in pregnancies with abnormally invasive placentation. We sought to determine if there is an association between PPH, IRP, and psychological sequelae.

OBJECTIVES

Seventy-three women who underwent IRP due to PPH or were at high risk for PPH.

METHOD

A structured questionnaire was sent to all women.

RESULTS

Overall 49 women returned the questionnaire. Two-thirds of the women developed psychological sequelae and one-third reported a lack of professional support. Nine women had symptoms of post-traumatic stress disorder. Psychological sequelae were not associated with a volume of bleeding, whether or not hysterectomy was performed, or whether the IRP was performed as an emergency procedure or prophylactically. However, women who had elective IRP and no hysterectomy performed had significantly less fear of death compared to the rest of the study population.

CONCLUSIONS

We observed a high rate of psychological sequelae associated with IRP. Lack of proper professional support may have contributed to the development of post-traumatic psychological sequelae suggesting a need for debriefing in such women.

Post traumatic stress disorder (PTSD): The psychological sequelae of abnormally invasive placenta (AIP)

INTRODUCTION

Abnormally invasive placenta (AIP) is a rare pregnancy complication often resulting in postpartum haemorrhage (PPH) and emergency peripartum hysterectomy (EPH). The risk of developing post traumatic stress disorder (PTSD) following unexpectedly traumatic childbirth is known however there is no evidence regarding PTSD in AIP. This pilot study assesses the risk of PTSD for women with AIP compared to women having an uncomplicated caesarean delivery (CD) or unexpected PPH or EPH.

METHODS

Retrospective case-controlled questionnaire study in a UK Tertiary obstetric unit. Women with AIP (Group-1) were matched by delivery date to control groups: Group-2, women with an uncomplicated CD; Group-3 women referred to a specialist clinic for suspected AIP, but had a normal placenta and uncomplicated CD; Group-4, women who had an unexpected EPH and/or severe (>3000 mls) PPH. 218 women were sent a validated PTSD screening questionnaire (Impacts of Events Scale-Revised [IES-R]).

RESULTS

Likelihood of PTSD was recorded for 69 women who responded, revealing significantly higher PTSD scores for women with AIP compared to uncomplicated CD (P = 0.001). No significant difference was seen between AIP and EPH/PPH (P = 0.89). The number of women with scores high enough to indicate probable PTSD was significantly greater with AIP than uncomplicated CD group (P = 0.045).

DISCUSSION

This study demonstrates that women antenatally diagnosed with AIP and anticipating a potentially traumatic delivery, are at significantly increased risk of developing PTSD. Improved awareness of the negative psychological impact of AIP may increase the number of women being identified and treated, thereby improving their quality of life.

Incidence and recurrence rate of postpartum hemorrhage and manual removal of the placenta: A longitudinal linked national cohort study in The Netherlands

OBJECTIVE

We studied the incidence of postpartum hemorrhage and manual removal of the placenta and their recurrence rate in a subsequent pregnancy. We hypothesized that the risk of recurrence was dependent on the gestational age at first birth and whether or not a manual removal of the placenta was necessary. Knowledge on this subject can potentially improve counselling, prevention and management in obstetric care for women at risk for PPH or identify women at low risk for recurrence.

STUDY DESIGN

This was a retrospective national cohort study consisting of women with two consecutive singleton deliveries between 1999 and 2009 in the Netherlands. A longitudinal linked national cohort with information on subsequent singleton deliveries in the Netherlands was used. Main outcome measures were: postpartum hemorrhage (defined as ≥1000 mL after vaginal delivery or Caesarean section) and manual removal of the placenta. We calculated incidence and recurrence rates of postpartum hemorrhage and manual removal of the placenta for all women and stratified by gestational age.

RESULTS

After application of in- and exclusion criteria 359 737 women were studied. A total of 5.4% women experienced postpartum hemorrhage in the first pregnancy and 2.7% of women had a manual removal of the placenta. The risk of postpartum hemorrhage in a subsequent pregnancy was significantly higher in women with a history of postpartum hemorrhage compared to women without a previous postpartum hemorrhage (18% vs 3.9%, adjusted odds ratio 4.5; 95% confidence interval 4.3-4.7). The risk of manual removal of the placenta in the second pregnancy was only 1.4% in women without a previous manual removal compared to 17% of women with a previous manual removal of the placenta. Women with a manual removal of the placenta in the first pregnancy between 32 and 37 weeks were most at risk for recurrence (adjusted odds ratio 8.9; 95% confidence interval 7.2-11).

CONCLUSION

Women with a previous delivery complicated by postpartum hemorrhage or manual removal of the placenta are at increased risk for recurrence. The magnitude of this risk is highest in women with deliveries beyond 32 weeks in the first pregnancy.

Morphological evaluation of cervix using MRI at 32 to 36 weeks of gestation: Findings for predicting invasive placenta previa

This study is to investigate the role of cervical morphology evaluated by magnetic resonance imaging (MRI) in predicting invasive placenta previa (IPP).Totally 105 cases of pregnant women underwent prenatal placental MRI at 32 to 36 weeks of gestation for suspected IPP were included in this study. Cervical morphology (cervical length and placental protrusion) was evaluated independently by 2 radiologists. The association between the cervical morphology and surgery findings was analyzed.Totally, 57 pregnant women were confirmed as IPP. For invasion degree, there were 17 cases with placenta percreta and 40 with accreta. For invasion topography, there were 27 cases with S1 invasion and 30 with S2 invasion. The sensitivity and specificity for the MRI sign of placental protrusion in evaluating cervical invasion of IPP were 100% and 100%, respectively. All the 7 IPP patents with cervical invasion received total hysterectomy and had severe blood loss (3500-6000 mL). The IPP patients with S2 invasion had shorter cervical length than those with S1 invasion (2.66 ± 0.66 cm vs 3.24 ± 0.64 cm, P <.001). However, cervical lengths did not correlate with the degree of invasion (placenta percreta vs placenta accreta: 2.82 ± 0.86 vs 2.99 ± 0.60, P = .21).Placental protrusion is a reliable MRI sign for cervical invasion of IPP, and cervical lengths correlate with the invasion topography.

Demographic, psychosocial and clinical factors associated with postpartum depression in Kenyan women

BACKGROUND

Few longitudinal studies have examined associations between risk factors during pregnancy and mental health outcomes during the postpartum period. We used a cohort study design to estimate the prevalence, incidence and correlates of significant postpartum depressive symptoms in Kenyan women.

METHODS

We recruited adult women residing in an urban, resource-poor setting and attending maternal and child health clinics in two public hospitals in Nairobi, Kenya. A translated Kiswahili Edinburgh Postpartum Depression Scale was used to screen for depressive symptoms at baseline assessment in the 3rd trimester and follow up assessment at 6-10 weeks postpartum. Information was collected on potential demographic, psychosocial and clinical risk variables. Potential risk factors for postpartum depression were evaluated using multivariate logistic regression analysis.

RESULTS

Out of the 171 women who were followed up at 6-10 weeks postpartum, 18.7% (95% CI: 13.3-25.5) were found to have postpartum depression using an EPDS cut off of 10. In multivariate analyses, the odds of having postpartum depression was increased more than seven-fold in the presence of conflict with partner (OR = 7.52, 95% CI: 2.65-23.13). The association between antepartum and postpartum depression was quite strong but did not reach statistical significance (OR = 3.37, 95% CI: 0.98-11.64).

CONCLUSIONS

The high prevalence of significant postnatal depressive symptoms among Kenyan women underscores the need for addressing this public health burden. Depression screening and psychosocial support interventions that address partner conflict resolution should be offered as part of maternal health care.

Posttraumatic stress disorder related to postpartum haemorrhage: A systematic review

In some cases childbirth leads to negative psychological responses such as posttraumatic stress disorder (PTSD). Postpartum hemorrhage (PPH) is a common and major complication of childbirth, which occasionally requires emergency hysterectomy in severe cases. Patients often describe these complications as a traumatic experience. It is unknown whether PPH is a risk factor for developing PTSD. In this systematic review we summarize the current knowledge about the association between PPH with or without emergency hysterectomy and posttraumatic stress symptoms or PTSD. If PPH is a risk factor for PTSD, this will allow adequate preventive measures with the aim to reduce the long-term effects and socioeconomic problems associated with PTSD. To conduct this review MEDLINE, EMBASE, Web of Science, ClinicalTrials.gov, Cochrane Central Register of Controlled Trials, Cochrane Library and PsycINFO databases were searched for publications between January 1986 and October 2017. Manuscripts evaluating the association between PPH and peripartum emergency hysterectomy and PTSD or posttraumatic stress symptoms were included. Fifty-two articles met the criteria for full-text review. Seven articles were included in this review. Five studies focused on the association between PPH and PTSD and two studies evaluated the association between emergency hysterectomy and PTSD. Three studies found no association between PPH and PTSD. Two studies reported a higher risk of developing PTSD or posttraumatic stress symptoms after PPH. Two studies reported a higher risk of developing PTSD after emergency hysterectomy. Meta-analysis was not possible due to the heterogeneity of these studies. Based on the results of these studies there may be an association between PPH and PTSD. Secondly, it seems likely that an association exists between emergency postpartum hysterectomy and PTSD, but the strength of this conclusion is limited by the small amount of studies included.

T2-weighted balanced steady-state free procession MRI evaluated for diagnosing placental adhesion disorder in late pregnancy

OBJECTIVE

This study evaluated the imaging characteristics and accuracy of T2-weighted (T2W) balanced steady-state free procession (b-SSFP) magnetic resonance imaging, relative to b-SSFP or single-shot fast spin echo (SSFSE), for the diagnosis of placental adhesion disorder (PAD).

METHODS

Fifty-one pregnant patients suspected of PAD were examined with T2W b-SSFP, b-SSFP and SSFSE. The image types were independently analysed for signs of PAD: abnormal placental bulge (APB), dark intraplacental bands (DIB), placental heterogeneity (PH) and placental protrusion into adjacent structures (PPAS). The sequences were compared for muscle-to-placenta signal ratio, signs of PAD and area under the receiver operating characteristic curve (AUC) for diagnostic accuracy of PAD.

RESULTS

PAD was confirmed in 34 women. The muscle-to-placenta signal ratio was highest in the T2W b-SSFP. The diagnostic rates of APB in T2W b-SSFP were comparable to that of b-SSFP, but were significantly higher than that of SSFSE. The rates of PH in SSFE were comparable to that of b-SSFP, but both were significantly lower than that of T2W b-SSFP. The rates of DIB were significantly higher in T2W b-SSFP images compared with SSFSE. Rates of PPAS were comparable among three sequences. The AUCs of the T2W b-SSFP, b-SSFP and SSFSE were 0.966, 0.890 and 0.823, respectively.

CONCLUSION

T2W b-SSFP has high diagnostic accuracy for PAD relative to SSFSE or b-SSFP, which may be due to its high SNR, T2-weighting and lack of blur.

KEY POINTS

• Signal myometrium-to-placenta ratio was highest in the T2W b-SSFP images. • Diagnostic rate of APB in T2W b-SSFP was highest. • Diagnostic rate of DIB was higher in T2W b-SSFP than in SSFSE. • Diagnostic rate of PH in T2W b-SSFP was highest. • Maximum AUC for diagnostic accuracy of PAD was in T2W b-SSFP.

Obstetric risk factors for depression during the postpartum period in South Korea: a nationwide study

OBJECTIVE

Postpartum depression is related to many adverse effects in both mothers and their children; therefore, proper screening and early interventions are needed. This study aims to identify the risk factors of postpartum depression. Our primary focus is on obstetric risk factors.

METHODS

This study is a cross-sectional study which we extracted the data of women who gave birth between January 1st, 2010 and December 31st, 2012 from the Health Insurance Review and Assessment service (HIRA) database. We analyzed the data using multivariable logistic regression models.

RESULTS

A total of 17,483 (1.4%) women suffered from depression during the postpartum period. Younger (<20years) and advanced maternal age (≥35years), primiparity, previous depression, peripartum hysterectomy, uterine artery embolization, preterm delivery, placental abruption, cesarean delivery, induced labor, and preeclampsia were found to increase the likelihood of having depression after delivery.

CONCLUSIONS

Our findings suggest that there are several risk factors that lead women to postpartum depression. Therefore, early detection and well-management of the symptoms and risk factors for postpartum depression along with social support can help both physical and psychological conditions of women after childbirth.

Previous uterine artery embolization increases the rate of repeat embolization in a subsequent pregnancy

This study aimed to determine the rate of repeat uterine artery embolization (UAE) in women with a previous UAE. Study data were collected from the Korea National Health Insurance Claims Database of the Health Insurance Review and Assessment Service for 2009–2013. We enrolled women who had a first delivery in 2009 and a second delivery between 2010 and 2013. Among 226,408 women who had a first delivery in 2009, 296 underwent UAE. A total of 127,506 women had a second delivery between 2010 and 2013. Of 296 women who underwent UAE after the first delivery, 94 had a second delivery between 2010 and 2013. Women with a previous UAE had a higher rate of UAE at the second delivery than women without a previous UAE. Multivariate adjusted analysis showed that a UAE at the first delivery increased the rate of UAE at the second delivery (odds ratio 25.56, 95% confidence interval 9.86–66.23). Women with a previous UAE should be appropriately counseled and monitored for the need for a repeat UAE.

Risk factors for chronic post-traumatic stress disorder development one year after vaginal delivery: a prospective, observational study

Our study aimed to assess the prevalence of post-traumatic stress disorder (PTSD) after childbirth one year after vaginal delivery and to identify characteristics of women and deliveries associated with it. Questionnaires were mailed a year after delivery to 1103 women with prospectively collected delivery and postpartum data, including a question on day 2 assessing their experience of childbirth. PTSD was assessed a year later by the Impact of Event and Traumatic Event Scales; 22 women (4.2%, 95%CI 2.7-6.3%) met the PTSD diagnostic criteria and 30 (5.7%; 95%CI 3.9-8.0%) PTSD profile criteria. Factors associated with higher risk of PTSD profile were previous abortion (aOR 3.6, 95%CI 1.4-9.3), previous postpartum hemorrhage (Aor 5.3, 95%CI 1.3-21.4), and postpartum hemoglobin <9 g/dl (aOR 2.7, 95%CI 1.0-7.5). Among 56 women (10.3%) reporting bad childbirth memories at day 2 postpartum, 11 (21.1%) met PTSD diagnosis and 11 (21.1%) PTSD profile criteria a year later, compared with 11 (2.4%) (P < 0.001) and 18 (3.8%) (P < 0.001), respectively, of the 489 (87.7%) women with good memories. PTSD is not rare at one year after vaginal delivery in a low-risk population. A simple question at day 2 post partum may identify women most at risk of PTSD and help determine if early intervention is needed.
