Background: The rising trend in maternal mortality over the past 3 decades sets the United States apart from all other high-income countries. Multidisciplinary state and city Maternal Mortality Review Committees conduct comprehensive reviews of maternal deaths, including assessments of preventability and contributing factors., Objective: Assess preventability of and contributing factors to maternal mortality in the U.S., Study Design: This study is a secondary analysis of cross-sectional, population-based data from the most recent, publicly available Maternal Mortality Review Committee data from 40 state and 2 cities in the U.S. Preventability were analyzed among all deaths during pregnancy or within 1 year postpartum from any cause (pregnancy-associated deaths) and deaths during pregnancy or within 1 year postpartum from causes related to pregnancy or its management, but not from accidental causes (pregnancy-related deaths). We also explored preventability by cause-of-death and contributing factors grouped as community, patient-family, provider, facility, and health system factors., Results: Of deaths that occurred after 2010, between 53% to 93.8% of pregnancy-associated deaths and 45% to 100% of pregnancy-related deaths were deemed preventable across the 42 states and cities. Across the 10 states reporting pregnancy-related death preventability by cause-of-death, Maternal Mortality Review Committees deemed preventable >90% of deaths from preeclampsia-eclampsia and mental health conditions, >80% of deaths from hemorrhage and cardiovascular conditions, about 70% of deaths from infection and thrombotic embolism, and about 40% of deaths from amniotic fluid embolism and stroke. A total of 3345 contributing factors were described in Maternal Mortality Review Committee reports from 14 states in relation to 739 pregnancy-related deaths. While collectively patient-family and provider factors were most frequently noted as contributing to pregnancy-related deaths, the contribution of such factors varied between 6% to 56% and 18% to 42.3%, respectively, across the states. Based on data from 20 Maternal Mortality Review Committees with available information, racism or discrimination were noted in relation to 37.7% of pregnancy-related deaths., Conclusion: A large proportion of pregnancy-associated deaths and pregnancy-related deaths in the U.S. are preventable. However, likely due to differences in Maternal Mortality Review Committee membership, available data, and judgement employed to determine preventability, wide variation exists in the proportion of deaths deemed preventable and factors identified as contributing to such deaths across states. There is need to reevaluate the definitions, structure, and outputs for maternal death preventability assessments currently employed by a majority Maternal Mortality Review Committees to adequately inform state and national programming and policies., (Published by Elsevier Inc.)

Maternal mortality is a sentinel health indicator. To improve the identification of maternal deaths, a pregnancy question was added during the 2003 revision of the US standard death certificate. Its adoption across all states in the United States took 16 years (2003-2018), and therefore the National Center for Health Statistics did not provide the national maternal mortality rate between 2007 and 2018. During this time, researchers raised questions about the accuracy of the checkbox information, particularly regarding its contribution to overreporting of maternal deaths in the United States. Checkbox errors were especially evident for women aged >40 years and for nonspecific causes of death. In January 2020, the NCHS resumed the reporting of maternal mortality data and provided the 2018 figures using a new coding method (ie, the 2018 method). Despite internal analyses suggesting the presence of both high false positive and high false negative pregnancy checkbox errors, the National Center for Health Statistics reported identification of 658 maternal deaths nationwide and a maternal mortality rate of 17.4 deaths per 100,000 live births for 2018. The 2018 coding method restricts the entry of checkbox information to decedents aged 10-44 years; the information cannot, therefore, be entered for women aged >45 years when no pregnancy-related cause of death information is indicated on the death certificate. Reported deaths with a pregnancy or obstetrical condition entered in the cause of death section of the death certificate continue to be coded as maternal deaths regardless of age. The 2018 method likely corrects errors introduced by the use of the checkbox for women aged >45 years, but whether it provides accurate maternal mortality figures remains unknown. We call for efforts to urgently and systematically validate the pregnancy checkbox information. Post hoc coding adjustments cannot substitute for providing accurate and actionable maternal mortality data., (Copyright © 2020 Elsevier Inc. All rights reserved.)

Substance use during pregnancy is at least as common as many of the medical conditions screened for and managed during pregnancy. While harmful and costly, it is often ignored or managed poorly. Screening, brief intervention, and referral to treatment is an evidence-based approach to manage substance use. In September 2012, the US Centers for Disease Control and Prevention convened an Expert Meeting on Perinatal Illicit Drug Abuse to help address key issues around drug use in pregnancy in the United States. This article reflects the formal conclusions of the expert panel that discussed the use of screening, brief intervention, and referral to treatment during pregnancy. Screening for substance use during pregnancy should be universal. It allows stratification of women into zones of risk given their pattern of use. Low-risk women should receive brief advice, those classified as moderate risk should receive a brief intervention, whereas those who are high risk need referral to specialty care. A brief intervention is a patient-centered form of counseling using the principles of motivational interviewing. Screening, brief intervention, and referral to treatment has the potential to reduce the burden of substance use in pregnancy and should be integrated into prenatal care., (Copyright © 2016 Elsevier Inc.

Objective: The purpose of this study was to examine cesarean delivery morbidity and its predictors in the United States., Study Design: We used 2000-2011 Nationwide Inpatient Sample data to identify cesarean deliveries and records with 12 potential cesarean delivery complications, including placenta accreta. We estimated cesarean delivery morbidity rates and rate changes from 2000-2011, and fitted Poisson regression models to assess the relative incidence of morbidity among repeat vs primary cesarean deliveries and explore its predictors., Results: From 2000-2011, 76 in 1000 cesarean deliveries (97 in 1000 primary and 48 in 1000 repeat cesarean deliveries) were accompanied by ≥1 of 12 complications. The unadjusted composite cesarean delivery morbidity rate increased by 3.6% only among women with a primary cesarean delivery (P < .001); the unadjusted rate of placenta accreta increased by 30.8% only among women with a repeat cesarean deliveries (P = .025). The adjusted rate of overall composite cesarean delivery morbidity decreased by 1% annually from 2000-2011 (P < .001). Compared with women with a primary cesarean delivery, those women who underwent a repeat cesarean delivery were one-half as likely (incidence rate ratio, 0.50; 95% CI, 0.49-0.50) to experience a complication, but 2.13 (95% CI, 1.98-2.29) times more likely to have a placenta accreta diagnosis. Both cesarean delivery morbidity and placenta accreta were positively associated with age >30 years, non-Hispanic black race/ethnicity, the presence of a chronic medical condition, and delivery in urban, teaching, or larger hospitals., Conclusion: Overall, cesarean delivery morbidity declined modestly from 2000-2011, but placenta accreta became an increasingly important contributor to repeat cesarean delivery morbidity. Clinicians should maintain a high index of suspicion for abnormal placentation and make adequate preparations for patients who need cesarean deliveries., (Published by Elsevier Inc.)

Objective: The objective of the study was to provide national prevalence, patterns, and correlates of marijuana use in the past month and past 2-12 months among women of reproductive age by pregnancy status., Study Design: Data from 2007-2012 National Surveys on Drug Use and Health, a cross-sectional nationally representative survey, identified pregnant (n = 4971) and nonpregnant (n = 88,402) women 18-44 years of age. Women self-reported marijuana use in the past month and past 2-12 months (use in the past year but not in the past month). χ(2) statistics and adjusted prevalence ratios were estimated using a weighting variable to account for the complex survey design and probability of sampling., Results: Among pregnant women and nonpregnant women, respectively, 3.9% (95% confidence interval [CI], 3.2-4.7) and 7.6% (95% CI, 7.3-7.9) used marijuana in the past month and 7.0% (95% CI, 6.0-8.2) and 6.4% (95% CI, 6.2-6.6) used in the past 2-12 months. Among past-year marijuana users (n = 17,934), use almost daily was reported by 16.2% of pregnant and 12.8% of nonpregnant women; and 18.1% of pregnant and 11.4% of nonpregnant women met criteria for abuse and/or dependence. Approximately 70% of both pregnant and nonpregnant women believe there is slight or no risk of harm from using marijuana once or twice a week. Smokers of tobacco, alcohol users, and other illicit drug users were 2-3 times more likely to use marijuana in the past year than respective nonusers, adjusting for sociodemographic characteristics., Conclusion: More than 1 in 10 pregnant and nonpregnant women reported using marijuana in the past 12 months. A considerable percentage of women who used marijuana in the past year were daily users, met abuse and/or dependence criteria, and were polysubstance users. Comprehensive screening, treatment for use of multiple substances, and additional research and patient education on the possible harms of marijuana use are needed for all women of reproductive age., (Published by Elsevier Inc.)

Objective: We sought to explore how racial/ethnic minority-serving hospitals perform on 15 delivery-related indicators, and examine whether indicators vary by race/ethnicity within the same type of hospitals., Study Design: We used 2008 through 2011 linked State Inpatient Database and American Hospital Association data from 7 states, and designated hospitals with >50% of deliveries to non-Hispanic white, non-Hispanic black, and Hispanic women as white-, black-, and Hispanic-serving, respectively. We calculated indicator rates per 1000 deliveries by hospital type and, separately, for non-Hispanic white, non-Hispanic black, and Hispanic women within each hospital type. We fitted multivariate Poisson regression models to examine associations between delivery-related indicators and patient and hospital characteristics by hospital type., Results: White-serving hospitals offer obstetric care to an older and wealthier population than black- or Hispanic-serving hospitals. Rates of the most prevalent indicators examined (complicated vaginal delivery, complicated cesarean delivery, obstetric trauma) were lowest in Hispanic-serving hospitals. Generally, indicator rates were similar in Hispanic- and white-serving hospitals. Black-serving hospitals performed worse than other hospitals on 12 of 15 indicators. Indicator rates varied greatly by race/ethnicity in white- and Hispanic-serving hospitals, with non-Hispanic blacks having 1.19-3.27 and 1.15-2.68 times higher rates than non-Hispanic whites, respectively, for 11 of 15 indicators. Conversely, there were few indicator rate differences by race/ethnicity in black-serving hospitals, suggesting an overall lower performance of these hospitals compared to white- and Hispanic-serving hospitals., Conclusion: We found considerable differences in delivery-related indicators by hospital type and patients' race/ethnicity. Obstetric care quality measures are needed to track racial/ethnic disparities at the facility and population levels., (Published by Elsevier Inc.)

We review the evidence and identify limitations of the current literature on the effectiveness of brief interventions (≤5 intervention sessions) on illicit drug use, treatment enrollment/retention, and pregnancy outcomes among pregnant and postpartum women; and consider this evidence in the context of the broader brief intervention literature. Among 4 published studies identified via systematic review and meeting a priori quality criteria, we found limited, yet promising evidence of the benefit of brief interventions to reduce illicit drug use among postpartum women. Two of the 4 randomized controlled trials tested similar computer-delivered single-session interventions; both demonstrate effects on postpartum drug use. Neither of the 2 randomized controlled trials that assessed treatment use found differences between intervention and control groups. Studies examining brief interventions for smoking and alcohol use among pregnant women, and for illicit drug use in the general adult population, have shown small but statistically significant results of the effectiveness of such interventions. Larger studies, those that examine the effect of assessment alone on illicit drug use, and those that use technology-delivered brief interventions are needed to assess the effectiveness of brief interventions for drug use in the peripartum period., (Published by Elsevier Inc.)

Objective: The purpose of this study was to examine racial and ethnic disparities in severe maternal morbidity during delivery hospitalizations in the United States., Study Design: We identified delivery hospitalizations from 2008-2010 in State Inpatient Databases from 7 states. We used International Classification of Diseases, 9th Revision, codes to create severe maternal morbidity indicators during delivery hospitalizations. We calculated the rates of severe maternal morbidity that were measured with and without blood transfusion for 5 racial/ethnic groups: non-Hispanic white, non-Hispanic black, Hispanic, Asian/Pacific Islander, and American Indian/Alaska Native women. Poisson regression models were fitted to explore the associations between race/ethnicity and severe maternal morbidity after we controlled for potential confounders., Results: Overall, severe maternal morbidity rates that were measured with and without blood transfusion were 150.7 and 64.3 per 10,000 delivery hospitalizations, respectively. Non-Hispanic black, Hispanic, Asian/Pacific Islander, and American Indian/Alaska Native women had 2.1, 1.3, 1.2, and 1.7 times (all P < .05), respectively, higher rates of severe morbidity that were measured with blood transfusion compared with non-Hispanic white women; similar increased rates were observed when severe morbidity was measured without blood transfusion. Other significant positive predictors of severe morbidity were age <20 and ≥30 years, self-pay or Medicaid coverage for delivery, low socioeconomic status, and presence of chronic medical conditions., Conclusion: Severe maternal morbidity disproportionally affects racial/ethnic minority women, especially non-Hispanic black women. There is a need for a systematic review of severe maternal morbidities at the facility, state, and national levels to guide the development of quality improvement interventions to reduce the racial/ethnic disparities in severe maternal morbidity., (Published by Mosby, Inc.)

We review clinical care issues that are related to illicit and therapeutic opioid use among pregnant women and women in the postpartum period and outline the major responsibilities of obstetrics providers who care for these patients during the antepartum, intrapartum, and postpartum periods. Selected patient treatment issues are highlighted, and case examples are provided. Securing a strong rapport and trust with these patients is crucial for success in delivering high-quality obstetric care and in coordinating services with other specialists as needed. Obstetrics providers have an ethical obligation to screen, assess, and provide brief interventions and referral to specialized treatment for patients with drug use disorders. Opioid-dependent pregnant women often can be treated effectively with methadone or buprenorphine. These medications are classified as pregnancy category C medications by the Food and Drug Administration, and their use in the treatment of opioid-dependent pregnant patients should not be considered "off-label." Except in rare special circumstances, medication-assisted withdrawal during pregnancy should be discouraged because of a high relapse rate. Acute pain management in this population deserves special consideration because patients who use opioids can be hypersensitive to pain and because the use of mixed opioid-agonist/antagonists can precipitate opioid withdrawal. In the absence of other indications, pregnant women who use opioids do not require more intense medical care than other pregnant patients to ensure adequate treatment and the best possible outcomes. Together with specialists in pain and addiction medicine, obstetricians can coordinate comprehensive care for pregnant women who use opioids and women who use opioids in the postpartum period., (Copyright © 2014 Mosby, Inc.

Background: Despite abortion being legal, complications from induced abortion are the second leading cause of maternal mortality in Ghana. The objective of this study was to understand the decision-making process associated with induced abortion in Ghana., Study Design: Data were collected from female postabortion patients, male partners, family planning nurses and obstetricians/gynecologists at two teaching hospitals in Ghana using in-depth interviews and focus group discussions., Results: While experiences differ for married and single women, men are involved in abortion decision making directly, through "orders" to abort, or indirectly, through denying responsibility for the pregnancy. Health care providers can be barriers to seeking safe abortions in this setting., Conclusions: Women who choose to terminate a pregnancy without their male partners' knowledge should have the means (both financial and social) to do so safely. Interventions with health care providers should discourage judgemental attitudes and emphasize individually focused patient care., (Copyright © 2013 Elsevier Inc. All rights reserved.)

Background: Group, rather than individual, family planning counseling has the potential to increase family planning knowledge and use through more efficient use of limited human resources., Study Design: A randomized, noninferiority study design was utilized to identify whether group family planning counseling is as effective as individual family planning counseling in Ghana. Female gynecology patients were enrolled from two teaching hospitals in Ghana in June and July 2008. Patients were randomized to receive either group or individual family planning counseling. The primary outcome in this study was change in modern contraceptive method knowledge. Changes in family planning use intention before and after the intervention and intended method type were also explored., Results: Comparisons between the two study arms suggest that randomization was successful. The difference in change in modern contraceptive methods known from baseline to follow-up between the two study arms (group-individual), adjusted for study site, was -0.21, (95% confidence interval: -0.53 to 0.12) suggesting no difference between the two arms., Conclusions: Group family planning counseling was as effective as individual family planning counseling in increasing modern contraceptive knowledge among female gynecology patients in Ghana., (Copyright © 2013 Elsevier Inc.

Background: With changing patterns and increasing use of medical abortion in the United States, it is important to have accurate statistics on the use of this method regularly available. This study assesses the accuracy of medical abortion data reported annually to the Centers for Disease Control and Prevention (CDC) and describes trends over time in the use of medical abortion relative to other methods., Study Design: This analysis included data reported to CDC for 2001-2008. Year-specific analyses included all states that monitored medical abortion for a given year, while trend analyses were restricted to states that monitored medical abortion continuously from 2001 to 2008. Data quality and completeness were assessed by (a) examining abortions reported with an unspecified method type within the gestational age limit for medical abortion (med-eligible abortions) and (b) comparing the percentage of all abortions and med-eligible abortions reported to CDC as medical abortions with estimates based on published mifepristone sales data for the United States from 2001 to 2007., Results: During 2001-2008, the percentage of med-eligible abortions reported to CDC with an unspecified method type remained low (1.0%-2.2%); CDC data and mifepristone sales estimates for 2001-2007 demonstrated strong agreement [all abortions: intraclass correlation coefficient (ICC)=0.983; med-eligible abortions: ICC=0.988]. During 2001-2008, the percentage of abortions reported to CDC as medical abortions increased (p<.001 for all abortions and for med-eligible abortions). Among states that reported medical abortions for 2008, 15% of all abortions and 23% of med-eligible abortions were reported as medical abortions., Conclusion: CDC's Abortion Surveillance System provides an important annual data source that accurately describes the use of medical abortion relative to other methods in the United States., (Published by Elsevier Inc.)

Background: Despite having one of the most liberal abortion laws in sub-Saharan Africa, complications from induced abortion are the second leading cause of maternal mortality in Ghana., Study Design: The sample is composed of patients with pregnancy termination complications in Ghana between June and July 2008. The majority of patients report having had a spontaneous abortion (75%; n=439), while 17% (n=100) and 8% (n=46) report having had an induced abortion or an ectopic pregnancy, respectively. Factors associated with women in each of the three groups were explored using multinomial logistic regression., Results: When compared to women with spontaneous abortions, women with induced abortions were younger, poorer, more likely to report no religious affiliation, less likely to be married, more likely to report making the household decisions and more likely to fail to disclose this pregnancy to their partners. Within the induced abortion subsample, failure to disclose the most recent pregnancy was associated with already having children and autonomous household decision making., Conclusion: Identifying the individual and relationship characteristics of induced abortion patients is the first step toward targeted policies and programs aimed at reducing unsafe abortion in Ghana., (Copyright © 2011 Elsevier Inc.

We sought to describe characteristics of hospitalized reproductive-aged (15-44 years) women with seasonal (2005/2006 through 2008/2009) and 2009 pandemic influenza A (H1N1) virus infection. We used population-based data from the Emerging Infections Program in 10 US states, and compared characteristics of pregnant (n = 150) and nonpregnant (n = 489) seasonal, and pregnant (n = 489) and nonpregnant (n = 1088) pandemic influenza cases using χ(2) and Fisher's exact tests. Pregnant women represented 23.5% and 31.0% of all reproductive-aged women hospitalized for seasonal and pandemic influenza, respectively. Significantly more nonpregnant than pregnant women with seasonal (71.2% vs 36.0%) and pandemic (69.7% vs 31.9%) influenza had an underlying medical condition other than pregnancy. Antiviral treatment was significantly more common with pandemic than seasonal influenza for both pregnant (86.5% vs 24.0%) and nonpregnant (82.0% vs 55.2%) women. Pregnant women comprised a significant proportion of influenza-hospitalized reproductive-aged women, underscoring the importance of influenza vaccination during pregnancy., (Copyright © 2011.

Background: Stillbirths do not count in routine worldwide data-collating systems or for the Millennium Development Goals. Two sets of national stillbirth estimates for 2000 produced similar worldwide totals of 3·2 million and 3·3 million, but rates differed substantially for some countries. We aimed to develop more reliable estimates and a time series from 1995 for 193 countries, by increasing input data, using recent data, and applying improved modelling approaches., Methods: For international comparison, stillbirth is defined as fetal death in the third trimester (≥1000 g birthweight or ≥28 completed weeks of gestation). Several sources of stillbirth data were identified and assessed against prespecified inclusion criteria: vital registration data; nationally representative surveys; and published studies identified through systematic literature searches, unpublished studies, and national data identified through a WHO country consultation process. For 2009, reported rates were used for 33 countries and model-based estimates for 160 countries. A regression model of log stillbirth rate was developed and used to predict national stillbirth rates from 1995 to 2009. Uncertainty ranges were obtained with a bootstrap approach. The final model included log(neonatal mortality rate) (cubic spline), log(low birthweight rate) (cubic spline), log(gross national income purchasing power parity) (cubic spline), region, type of data source, and definition of stillbirth., Findings: Vital registration data from 79 countries, 69 nationally representative surveys from 39 countries, and 113 studies from 42 countries met inclusion criteria. The estimated number of global stillbirths was 2·64 million (uncertainty range 2·14 million to 3·82 million) in 2009 compared with 3·03 million (uncertainty range 2·37 million to 4·19 million) in 1995. Worldwide stillbirth rate has declined by 14·5%, from 22·1 stillbirths per 1000 births in 1995 to 18·9 stillbirths per 1000 births in 2009. In 2009, 76·2% of stillbirths occurred in south Asia and sub-Saharan Africa., Interpretation: This study draws attention to the dearth of reliable data in regions where most stillbirths occur. The estimated trend in stillbirth rate reduction is slower than that for maternal mortality and lags behind the increasing progress in reducing deaths in children younger than 5 years. Improved data and improved use of data are crucial to ensure that stillbirths count in global and national policy., Funding: The Bill & Melinda Gates Foundation through the Global Alliance to Prevent Prematurity and Stillbirth, Saving Newborn Lives/Save the Children, and the International Stillbirth Alliance.

Background: Despite liberal laws, abortions are a major cause of maternal morbidity and mortality in India., Study Design: This study uses health provider data (N=2039) collected in Bihar and Jharkhand states, India, in 2004. Logistic regression models are fitted to identify correlates of providers' practice of abortion services and intention to offer medical abortions., Results: While a majority of respondents (63.2%) provide abortion services, only 2.9% currently provide medical abortions and 23.8% intend to provide medical abortions. Private rather than public clinic providers and female rather than male providers are more likely to offer abortion services and intend to provide medical abortions. Aspects related to medical abortion's market demand, its safety, efficacy and perceived ease of delivery weigh more than patients' rights and personal interests on providers' decision to provide medical abortions., Conclusion: This study enlarges the knowledge base on abortion service providers and offers recommendations for improving access to safe abortion services in India.
