Obstetric anal sphincter injury by maternal origin and length of residence: a nationwide cohort study.

OBJECTIVE: To estimate the association between maternal origin and obstetric anal sphincter injury (OASI), and assess if associations differed by length of residence. DESIGN: Population-based cohort study. SETTING: The Medical Birth Registry of Norway. POPULATION: Primiparous women with vaginal livebirth of a singleton cephalic fetus between 2008 and 2017 (n = 188 658). METHODS: Multivariable logistic regression models estimated adjusted odds ratios (aORs) for OASI with 95% CI by maternal region of origin and birthplace. We stratified models on length of residence and paternal birthplace. MAIN OUTCOME MEASURES: OASI. RESULTS: Overall, 6373 cases of OASI were identified (3.4% of total cohort). Women from South Asia were most likely to experience OASI (6.2%; aOR 2.24, 95% CI 1.87-2.69), followed by those from Southeast Asia, East Asia & the Pacific (5.7%; 1.59, 1.37-1.83) and Sub-Saharan Africa (5.2%; 1.85, 1.55-2.20), compared with women originating from Norway. Among women born in the same region, those with short length of residence in Norway (0-4 years), showed the highest odds of OASI. Migrant women across most regions of origin had the lowest risk of OASI if they had a Norwegian partner. CONCLUSIONS: Primiparous women from Asian regions and Sub-Saharan Africa had up to two-fold risk of OASI, compared with women originating from Norway. Migrants with short residence and those with a foreign-born partner had higher risk of OASI, implying that some of the risk differential is due to sociocultural factors. Some migrants, especially new arrivals, may benefit from special attention during labour to reduce morbidity and achieve equitable outcomes. TWEETABLE ABSTRACT: Anal sphincter injury during birth is more common among Asian and Sub-Saharan migrants and particularly among recent arrivals.

Maternal Ethnicity and the Risk of Obstetrical Anal Sphincter Injury: A Retrospective Cohort Study.

OBJECTIVE: To explore the role of maternal ethnicity as a risk factor for obstetrical anal sphincter injury (OASI). METHODS: A retrospective cohort study of all women with singleton gestations who had a vaginal delivery at term, between January 2014 and October 2017, at a single center. OASI was defined as a third-degree perineal tear (anal sphincter complex) or a fourth-degree perineal tear (anorectal mucosa). The characteristics of women with and without OASIs were compared. Multiple logistic regression was performed to account for potential confounders, including ethnicity. RESULTS: During the study period, 11 012 women were eligible for inclusion, of whom 336 (3.1%) had an OASI; 313 (93.1%) had a third-degree tear, and 23 (6.9%) had a fourth-degree tear. Women with OASIs were characterized by younger maternal age (<35 years), Asian ethnicity, nulliparity, neonatal birth weight ≥3500 grams, midline and mediolateral episiotomy, second stage of labour lasting ≥60 minutes, and assisted vaginal delivery. After adjusting for potential confounders, Asian ethnicity remained independently associated with increased risk of OASI (adjusted odds ratio 2.07; 95% CI 1.6-2.7) whereas mediolateral episiotomy was independently associated with decreased risk of OASI (adjusted odds ratio 0.64; 95% CI 0.5-0.9). CONCLUSION: Asian ethnicity is independently associated with increased risk of OASI. Although midline episiotomy increases the risk of OASI, mediolateral episiotomy may protect against OASI, and should be considered in high-risk patients.

Birth hospital and racial and ethnic differences in severe maternal morbidity in the state of California.

BACKGROUND: Birth hospital has recently emerged as a potential key contributor to disparities in severe maternal morbidity, but investigations on its contribution to racial and ethnic differences remain limited. OBJECTIVE: We leveraged statewide data from California to examine whether birth hospital explained racial and ethnic differences in severe maternal morbidity. STUDY DESIGN: This cohort study used data on all births at ≥20 weeks gestation in California (2007-2012). Severe maternal morbidity during birth hospitalization was measured using the Centers for Disease Control and Prevention index of having at least 1 of the 21 diagnoses and procedures (eg, eclampsia, blood transfusion, hysterectomy). Mixed-effects logistic regression models (ie, women nested within hospitals) were used to compare racial and ethnic differences in severe maternal morbidity before and after adjustment for maternal sociodemographic and pregnancy-related factors, comorbidities, and hospital characteristics. We also estimated the risk-standardized severe maternal morbidity rates for each hospital (N=245) and the percentage reduction in severe maternal morbidity if each group of racially and ethnically minoritized women gave birth at the same distribution of hospitals as non-Hispanic white women. RESULTS: Of the 3,020,525 women who gave birth, 39,192 (1.3%) had severe maternal morbidity (2.1% Black; 1.3% US-born Hispanic; 1.3% foreign-born Hispanic; 1.3% Asian and Pacific Islander; 1.1% white; 1.6% American Indian and Alaska Native, and Mixed-race referred to as Other). Risk-standardized rates of severe maternal morbidity ranged from 0.3 to 4.0 per 100 births across hospitals. After adjusting for covariates, the odds of severe maternal morbidity were greater among nonwhite women than white women in a given hospital (Black: odds ratio, 1.25; 95% confidence interval, 1.19-1.31); US-born Hispanic: odds ratio, 1.25; 95% confidence interval, 1.20-1.29; foreign-born Hispanic: odds ratio, 1.17; 95% confidence interval, 1.11-1.24; Asian and Pacific Islander: odds ratio, 1.26; 95% confidence interval, 1.21-1.32; Other: odds ratio, 1.31; 95% confidence interval, 1.15-1.50). Among the studied hospital factors, only teaching status was associated with severe maternal morbidity in fully adjusted models. Although 33% of white women delivered in hospitals with the highest tertile of severe maternal morbidity rates compared with 53% of Black women, birth hospital only accounted for 7.8% of the differences in severe maternal morbidity comparing Black and white women and accounted for 16.1% to 24.2% of the differences for all other racial and ethnic groups. CONCLUSION: In California, excess odds of severe maternal morbidity among racially and ethnically minoritized women were not fully explained by birth hospital. Structural causes of racial and ethnic disparities in severe maternal morbidity may vary by region, which warrants further examination to inform effective policies.

Childbirth experiences of Sudanese women living with obstetric fistula - A qualitative study.

BACKGROUND: Obstetric Fistula results from failure to manage obstructed labor in a timely manner; the failure can be attributed to many factors. Therefore, the study seeks to provide a better understanding of the circumstances surrounding the occurrence of Obstetric Fistula using the Three-Delays model. METHODS: Semi-structured interviews were conducted with 19 women living with OF. Study participants were recruited from the Dr. Abbu Fistula Center and the Fistula Re-integration Center in Khartoum, Sudan. Thematic analysis was used to analyze the study findings. The Three-Delays Model guided the analysis and discussion of these findings. RESULTS: The majority (11 out of 19) experienced more than one delay and six of the participants had all the three delays. Women were kept at home by midwives or family members for days until the baby was dead or the woman showed severe signs of complications. Many of the participants went through injurious vaginal labor which could have been prevented if they had had timely access to a caesarian section. CONCLUSION: In order to reduce the delays in seeking care, special attention must be paid to raising women's, husbands' and the community's awareness about danger signs that may arise before and during childbirth, the benefits of skilled birth attendance, and where and when to seek help. In addition, the provision of information regarding where to find Emergency Obstetric Care services and a birth preparedness plan would facilitate prompt care-seeking behavior. More resources must be allocated to strengthen the quality and coverage of reproductive health services.

Maternal mortality trends at the Princess Marina and Nyangabwe referral hospitals in Botswana.

Despite the fact that about 94% of pregnant women attend ANC, 95% deliver at health facilities and 99% deliveries are assisted by skilled birth attendants in Botswana, the national Maternal Mortality Rate is still high. OBJECTIVES: To determine the trend of MMR at Princess Marina and Nyangabwe referral hospitals before and after EMOC training. METHODS: Retrospective longitudinal quantitative study design was used to collect data on maternal deaths. Demographic characteristics, maternal death causes, gestation at ANC registration and pregnancy risks were collected for the period before EMOC training and after training, analysed and compared. Descriptive statistics and frequency tables were used. FINDINGS: Maternal deaths were 33 and 41 before and after EMOC training respectively. Majority of the maternal deaths, 78.8% and 70.7% before and after EMOC training respectively occurred among young women in the reproductive ages. Eclampsia was the commonest cause of maternal death before EMOC between training & and 58% and 66% of maternal deaths before and after EMOC training respectively occurred among women who had attended ANC services four or more times. CONCLUSION: Maternal deaths at the hospitals remained similar during the two periods. Qualitative studies are needed to determine why EMOC training has not resulted in significant reduction in MMR in Botswana.

Risk for delivery complications in Robson Group 1 for non-Western women in Norway compared with ethnic Norwegian women - A population-based observational cohort study.

OBJECTIVES: To assess the pregnancy outcome of low-risk pregnancies for women originating from non-Western countries compared with ethnic Norwegian women. STUDY DESIGN: A retrospective population-based observational cohort study with prospectively registered data. Conducted at Stavanger University Hospital, Norway, with approximately 4800 deliveries annually, from 2009 to 2015. We included women with low-risk pregnancies of non-Western origin (n = 1413), born in Africa (n = 224), Asia (n = 439), Eastern Europe (n = 499), Middle East (n = 138), South America (n = 85), Western (n = 979), and ethnic Norwegian women (n = 7028). MAIN OUTCOME MEASURES: The relative risk of emergency cesarean section or postpartum hemorrhage by country of origin was estimated by odds ratios with 95% confidence intervals using logistic multiple regression. RESULTS: In total, the pregnancy outcomes of 9392 women were analyzed. Risk of emergency cesarean section was significantly higher for women originating from Asia (aOR: 1.887), followed by Africans (aOR: 1.705). Lowest risk was found in women originating from South America (aOR: 0.480). Risk of postpartum hemorrhage was significantly higher in women originating from Asia (aOR: 1.744) compared to Norwegians. CONCLUSION: Even in a low-risk population, women originating from Asia and Africa had an elevated risk of adverse pregnancy outcome compared to the Norwegian group. The elevated risk should be considered by obstetric care providers, and we suggest that women originating from Asia and Africa would benefit from a targeted care during pregnancy and childbirth.

Associations Between Maternal Obesity and Race, with Obstetric Anal Sphincter Injury: A Retrospective Cohort Study.

This retrospective cohort study examined associations between maternal body mass index (BMI), race, and obstetric anal sphincter injury (OASI) (3rd/4th degree perineal lacerations). Obstetric anal sphincter injury may lead to significant maternal morbidity, and a more thorough understanding of risk factors for this complication may guide providers in patient counseling and procedures such as episiotomy or operative vaginal delivery. Vaginal deliveries performed at Kapi'olani Medical Center for Women and Children from 2008-2015 were included. Maternal body mass index at delivery was used and OASIs identified through International Classification of Diseases codes. Demographic/clinical variables were summarized through descriptive statistics. Adjusted odds ratios were calculated using multiple logistic regression. Of the 25,594 deliveries included, 1,198 (4.7%) involved an OASI. OASI prevalence differed by BMI (P < .0001). The prevalence was highest in women with BMI < 30 kg/m2 (5.3%) and then decreased as BMI increased with women with BMI ≥ 50 demonstrating the lowest prevalence (1.7%). Compared to women with BMI < 30 kg/m2, women with BMI > 50 kg/m2 had a lower odds of OASI (OR 0.31 [95%CI 0.11 - 0.83]), which persisted after adjustment (aOR 0.28 [95%CI 0.08-0.96]). OASI also differed by race (P < .0001), with Native Hawaiian and other Pacific Islanders (NHOPI) demonstrating the lowest prevalence (3.0%) and Asians the highest (5.6%). After adjustment, compared to White women, NHOPI women had lower OASI prevalence that met the borderline of statistical significance (aOR 0.79 [95%CI 0.62-1.01]), while Asian women continued to demonstrate increased prevalence (aOR 1.50 [95% CI 1.22-1.85]). We conclude that obese women, including those with BMI ≥ 50 kg/m2, have lower OASI prevalence. Race is also a significant factor, with Asians almost double the prevalence of NHOPIs. These findings contribute to evidence-based, individualized patient counseling on OASI.

Delivery and its complications among women of Somali, Kurdish, and Russian origin, and women in the general population in Finland.

INTRODUCTION: Limited information is available on delivery and its complications among migrant women in Finland. We compared mode of delivery, delivery complications, and use of pain medication during delivery between migrant women of Somali, Kurdish, and Russian origin and women in the general population in Finland. METHODS: The women were of Russian (n = 318), Somali (n = 583), and Kurdish (n = 373) origin and 243 women from the general population (reference group) who had given birth in Finland between 2004 and 2014. The data were obtained from the National Medical Birth Register and the Hospital Discharge Register. The most recent birth of each woman was included in the analyses. The main statistical methods were logistic regression analyses adjusting for age, parity, body mass index, gestational age, and smoking during pregnancy. RESULTS: Vaginal delivery was the most common mode of delivery among all study groups (79%-89%). The prevalence of any delivery complications varied between 15% and 19% among all study groups. When adjusted for confounders, Russian women had lower odds (OR 0.49; CI 0.29-0.82) of having a cesarean delivery, whereas Somali and Kurdish women did not differ from the reference group. Somali women had an increased risk of any delivery complications (OR 1.62; CI 1.03-2.55) compared with the reference group. No differences were observed in the use of pain medication between the groups. CONCLUSION: Delivery complications were more common among migrant Somali women than among women in the general Finnish population. Somali women represent a high-risk group calling for special attention and care.

Cultural perceptions influencing obstetric complications among women in Kaduna, Northwestern Nigeria.

BACKGROUND: Maternal mortality remains a public health challenge despite the global progress made toward its reduction. Cultural beliefs and traditional practices contribute to delays and poor access to maternal health services. This study examined cultural perceptions influencing obstetric complications among women who delivered at Yusuf Dantsoho Memorial Hospital, Tudun-Wada, Kaduna. METHODOLOGY: The study was a cross-sectional study conducted at the Obstetrics and Gynecology Department of Yusuf Dantsoho Memorial General Hospital, Tudun-Wada, Kaduna, from February to April 2014. Two hundred and six women who delivered during the study period irrespective of their booking status and consented to participate in the study were recruited consecutively. Data were collected using a structured questionnaire. RESULTS: Majority of the participants were Hausas (74.8%), Muslims (94.7%), married (99.0%), unemployed (45.1%), and within the age group of 20-29 years (58.7%). Most had secondary education (44.2%). The most frequent maternal complications encountered were prolonged obstructed labor (27.7%), obstetric hemorrhage (23.4%), severe preeclampsia/eclampsia (18.2%), and sepsis (5.8%). "Feeling embarrassed if delivered in hospital" was significantly associated with prolonged obstructed labor, while "feeling proud if delivered at home" was five times more significantly associated with obstetric hemorrhage. CONCLUSION AND RECOMMENDATIONS: Cultural perceptions and traditional practices are major causes of primary delay in accessing maternal health services. The study emphasizes the importance of maternal health education among women in this region. Cultural perceptions and their influence on maternal mortality and morbidity should be integrated into health education programs.

Caesarean section among immigrants with different obstetrical risks.

AIM: To determine the variation in caesarean section rates among immigrant populations. BACKGROUND: Australia is one of the most multicultural in the world and is also among those with the highest caesarean section rates. DESIGN: Secondary data analysis. METHODS: Routinely collected data from a Local Heath District between 2011 and 2015 were analysed. Women were categorized into regional groups based on country of birth. Obstetrical risk was classified using the Robson classification. RESULTS/FINDINGS: In total 48 711 women gave birth, of whom 64.0% were born overseas; 13 966 had a caesarean section (28.7%). South and Central Asia women had a high number of caesarean sections (n = 4139; 29.6% of all caesarean sections), a high overall adjusted caesarean section rate (31.4%; 95% CI, 30.5%-32.3%), and consistently high caesarean section rates among women with single cephalic term pregnancy without a previous caesarean section. High adjusted caesarean section rates were seen among South East Asia women with nulliparous, single cephalic, term pregnancy, and spontaneous labour. Demographic and clinical characteristics explained 83.5% of the variation in overall caesarean section rates between country of birth and 21.8% to 100% depending on Robson group. CONCLUSIONS: Caesarean section rates varied by country of birth and within some Robson groups. The studied factors had various effects on the variation in caesarean section rates between country of birth and Robson groups.

The Great Divide: Country of birth as a risk factor for obstetric anal sphincter injuries.

BACKGROUND: Obstetric anal sphincter injuries (OASIS) can complicate up to 6% of births and are a major contributor to preventable maternal morbidity. Asian women have a risk of third and fourth degree perineal tears up to four times greater than women of other ethnicities in the same community, but the lack of differentiation of Asian women into regional groups has limited insight into the reasons behind their increased risk. AIMS: To investigate risk of OASIS associated with country of birth. METHODS: This was a retrospective cohort study of all women with a singleton, nulliparous pregnancy who delivered vaginally by spontaneous vaginal birth or an instrumental delivery between 1 January 2009 and 31 December 2015. The demographics of women who experienced OASIS were compared with those women who had minor perineal trauma. RESULTS: From January 2009 to December 2015 there were 10 750 singleton, nulliparous and natural vaginal birth (NVB), forceps or vacuum deliveries. Of these deliveries, 581 (5.4%) werehad third degree tears and 36 (0.3%) fourth degree tears. Women born in South Asia were at a much higher risk of OASIS than other groups, including women born in other Asian countries, compared to the Australian/New Zealand cohort. One in every 10 nulliparous South Asian women having a singleton vaginal or instrumental delivery will sustain an OASIS. CONCLUSIONS: Our study further confirms the role of Asian ethnicity in the risk of OASIS, and is the second to confirm that South Asian women are at a dramatically increased risk.

Racial/Ethnic Differences in Labor Induction in a Contemporary US Cohort: A Retrospective Cohort Study.

OBJECTIVE: To examine labor induction by race/ethnicity and factors associated with disparity in induction. STUDY DESIGN: This is a retrospective cohort study of 143,634 women eligible for induction ≥24 weeks' gestation from 12 clinical centers (2002-2008). Rates of labor induction for each racial/ethnic group were calculated and stratified by gestational age intervals: early preterm (240/7-336/7), late preterm (340/7-366/7), and term (370/7-416/7 weeks). Multivariable logistic regression examined the association between maternal race/ethnicity and induction controlling for maternal characteristics and pregnancy complications. The primary outcome was rate of induction by race/ethnicity. Inductions that were indicated, non-medically indicated, or without recorded indication were also compared. RESULTS: Non-Hispanic black (NHB) women had the highest percentage rate of induction, 44.6% (p < 0.001). After adjustment, all racial/ethnic groups had lower odds of induction compared with non-Hispanic white (NHW) women. At term, NHW women had the highest percentage rate (45.4%) of non-medically indicated or induction with no indication (p < 0.001). CONCLUSION: Compared with other racial/ethnic groups, NHW women were more likely to undergo non-medically indicated induction at term. As labor induction may avoid the occurrence of stillbirth, whether this finding explains part of the increased risk of stillbirth for NHB women at term merits further research.

A cosmopolítica da gestação, do parto e do pós-parto: autoatenção e medicalização entre os índios Munduruku / The cosmopolitics of pregnancy, childbirth and postpartum: self-attention and medicalization among Munduruku Indians

A pesquisadora Raquel Paiva Dias-Scopel, do Instituto Leônidas e Maria Deane (ILMD/Fiocruz Amazônia), levanta questões sobre a valorização e respeito à diversidade étnica e cultural dos povos indígenas e a difícil interface com o processos de medicalização e do direito ao acesso aos serviços de saúde biomédicos. O livro é parte da Coleção Saúde dos Povos Indígenas, da Editora Fiocruz e partiu da tese de doutorado defendida em 2014 no Programa de Pós-Graduação em Antropologia Social da Universidade Federal de Santa Catarina (UFSC). Foi publicado pela primeira vez em 2015 pela Associação Brasileira de Antropologia com o título A Cosmopolítica da Gestação, Parto e Pós-Parto: práticas de autoatenção e processo de medicalização entre os índios Munduruku. No prefácio da primeira edição, sua orientadora, a doutora em antropologia e professora titular da UFSC, Esther Jean Langdon, ressalta que o conceito fundamental deste livro é da autoatenção, que aponta para o reconhecimento da autonomia e da criatividade da coletividade, principalmente da família, como núcleo que articula os diferentes modelos de atenção ou cuidado da saúde.

Survival and negotiation: narratives of severe (near-miss) neonatal complications of Syrian women in Lebanon.

The World Health Organization has elaborated a maternal and neonatal near-miss reporting, audit and feedback system designed to improve the quality of care during and after childbirth. As part of a four-hospital comparative study in the Middle East, this article discusses the experiences of mothers whose newborns suffered from severe complications at birth in the Rafik Hariri University Hospital, the only public hospital in Beirut. Based on in-depth home interviews several weeks after childbirth, it aims to explore the experience of neonatal near-miss events through the mothers' birth narratives. The central concerns of these vulnerable and marginalised women regarded access to neonatal care, and how to negotiate hospital bureaucracy and debt. It argues that financial and bureaucratic aspects of the near-miss event should be part of the audit system and policy-making, alongside medical issues, in the quest for equitable access to and management of quality perinatal care.

Ethnic differences in maternal near miss.

PURPOSE: To evaluate the association between ethnic differences and the occurrence of maternal near miss (MNM) in the Amazon and Northeast regions of Brazil. METHODS: This is a secondary analysis of a national cross-sectional study focused on the assessment of care to pregnancy, childbirth, and infants under 1 year of age. Ethnicity was classified as white, black or indigenous. Ethnic distribution by state and region, the proportion of severe maternal complications and related procedures, and the prevalence of MNM and its criteria were calculated for the ethnic groups. Risks for MNM were estimated per sociodemographic characteristics and healthcare received by ethnic group, using prevalence ratios adjusted by all predictors and by the sampling method. RESULTS: 76% of the 16.783 women were black, 20% white and 3.5% indigenous. Around 36% reported any complication related to pregnancy and the most frequent were hemorrhage (27-31%), and infection (7.1-9.0%). The MNM ratio was higher among indigenous (53.1) and black (28.4) than in white women (25.7). For black women, the risks of MNM were lower for private prenatal care and hospital admission for conditions other than hypertension, while higher for cesarean section and peregrination. For indigenous, the risks of MNM were lower for private prenatal care, and higher for a longer time to reach the hospital. For white women, only the low number of prenatal visits increased the risk of MNM. CONCLUSIONS: The occurrence of MNM was higher for indigenous and black than for white women.

Unsettling the fistula narrative: cultural pathology, biomedical redemption, and inequities of health access in Niger and Ethiopia.

Obstetric fistula, a maternal childbirth injury that results in chronic incontinence, affects an estimated one million women in the global south. In the course of media and donor coverage on this condition, fistula sufferers have been branded as 'child brides' who, following the onset of their incontinence, become social pariahs and eventually find physical and social redemption through surgical repair. This narrative framing pits the violence of 'culture' against the potency of biomedical salvation. Based on over two years of ethnographic research at fistula repair centres in Niger and Ethiopia, this paper challenges this narrative and argues that most women with obstetric fistula remain embedded in social relations, receive continued familial support, and, unexpectedly, experience ambiguous surgical outcomes. This paper interrogates the existing logics of the fistula narrative that have had the unintended effects of obscuring global structural inequalities and diverting attention away from systemic health access reforms.

Maternal Asian ethnicity and obstetric intrapartum intervention: a retrospective cohort study.

BACKGROUND: Maternal ethnicity is a recognized risk factor for stillbirth, such that South Asian women have higher rates than their Caucasian counterparts. However, whether maternal ethnicity is a risk factor for intrapartum outcomes is less clear. The aim of this study is to explore associations between maternal country of birth, operative vaginal delivery and emergency cesarean section, and to identify possible mechanisms underlying any such associations. METHODS: We performed a retrospective cohort study of singleton term births among South Asian, South East/East Asian and Australian/New Zealand born women at an Australian tertiary hospital in 2009-2013. The association between maternal country of birth, operative vaginal birth and emergency cesarean was assessed using multivariate logistic regression. RESULTS: Of the 31,932 births, 54% (17,149) were to Australian/New Zealand-born women, 25% (7874) to South Asian, and 22% (6879) to South East/East Asian born women. Compared to Australian/New Zealand women, South Asian and South East/East Asian women had an increased rate of both operative vaginal birth (OR 1.43 [1.30-1.57] and 1.22 [1.11-1.35] respectively, p < 0.001 for both) and emergency cesarean section (OR 1.67 [1.53-1.82] and 1.16 [1.04-1.26] respectively, p < 0.001 and p = 0.007 respectively). While prolonged labor was the predominant reason for cesarean section among Australian/New Zealand and South East/East Asian women, fetal compromise accounted for the majority of operative births in South Asian women. CONCLUSION: South Asian and South East/East Asian women experience higher rates of both operative vaginal birth and cesarean section in comparison to Australian/New Zealand women, independent of other risk factors for intrapartum interventions.

Black-white differences in severe maternal morbidity and site of care.

BACKGROUND: For every maternal death, >100 women experience severe maternal morbidity, which is a life-threatening diagnosis, or undergo a life-saving procedure during their delivery hospitalization. Similar to racial/ethnic disparities in maternal death, black women are more likely to experience severe maternal morbidity than white women. Site of care has received attention as a mechanism to explain disparities in other areas of medicine. Data indicate that black women receive care in a concentrated set of hospitals and that these hospitals appear to provide lower quality of care. Whether racial differences in the site of delivery contribute to observed black-white disparities in severe maternal morbidity rates is unknown. OBJECTIVE: The purpose of this study was to determine whether hospitals with high proportions of black deliveries have higher severe maternal morbidity and whether such differences contribute to overall black-white disparities in severe maternal morbidity. STUDY DESIGN: We used a published algorithm to identify cases of severe maternal morbidity during deliveries in the Nationwide Inpatient Sample of the Healthcare Cost and Utilization Project for 2010 and 2011. We ranked hospitals by their proportion of black deliveries into high black-serving (top 5%), medium black-serving (5% to 25% range), and low black-serving hospitals. We analyzed the risks of severe maternal morbidity for black and white women by hospital black-serving status using logistic regressions that were adjusted for patient characteristics, comorbidities, hospital characteristics, and within-hospital clustering. We then derived adjusted rates from these models. RESULTS: Seventy-four percent of black deliveries occurred at high and medium black-serving hospitals. Overall, severe maternal morbidity occurred more frequently among black than white women (25.8 vs 11.8 per 1000 deliveries, respectively; P < .001); after adjustment for the distribution of patient characteristics and comorbidities, this differential declined but remained elevated (18.8 vs 13.3 per 1000 deliveries, respectively; P < .001). Women who delivered in high and medium black-serving hospitals had elevated rates of severe maternal morbidity rates compared with those in low black-serving hospitals in unadjusted (29.4 and 19.4 vs 12.2 per 1000 deliveries, respectively; P < .001) and adjusted analyses (17.3 and 16.5 vs 13.5 per 1000 deliveries, respectively; P < .001). Black women who delivered at high black-serving hospitals had the highest risk of poor outcomes. CONCLUSION: Most black deliveries occur in a concentrated set of hospitals, and these hospitals have higher severe maternal morbidity rates. Targeting quality improvement efforts at these hospitals may improve care for all deliveries and disproportionately impact care for black women.

Maternal complications associated with stillbirth delivery: A cross-sectional analysis.

This study sought to identify delivery complications associated with stillbirth labour and delivery. We conducted a retrospective chart review evaluating stillbirth demographics, pregnancy and maternal risk factors, and complications of labour and delivery. We performed bivariable analysis and multivariable logistic regression to evaluate factors associated with medical complications and variations by race. Our cohort included 543 mothers with stillbirth, of which two-thirds were African-American. We noted high rates of shoulder dystocia, clinical chorioamnionitis, postpartum haemorrhage and retained placenta in women with stillbirths. Thirty-three women (6%) experienced at least one serious maternal complication. Complication rates did not vary by maternal race. Providers who perform obstetrical care should be alert to the high rate of maternal medical complications associated with labour and delivery of a stillbirth foetus.
