The national partnership for maternal safety

Recognition of the need to reduce maternal mortality and morbidity in the United States has led to the creation of the National Partnership for Maternal Safety. This collaborative, broad-based initiative will begin with three priority bundles for the most common preventable causes of maternal death and severe morbidity: obstetric hemorrhage, severe hypertension in pregnancy, and peripartum venous thromboembolism. In addition, three unit-improvement bundles for obstetric services were identified: a structured approach for the recognition of early warning signs and symptoms, structured internal case reviews to identify systems improvement opportunities, and support tools for patients, families, and staff that experience an adverse outcome. This article details the formation of the National Partnership for Maternal Safety and introduces the initial priorities.

Neonatal mortality for very low birth weight deliveries in South Carolina by level of hospital perinatal service

OBJECTIVE The purpose of this study was to determine whether neonatal mortality rates for very low birth weight (500 to 1499 g) infants born in South Carolina differ by level of perinatal services available at the hospital of birth. STUDY DESIGN Linked live birth certificates and infant death certificates for 1993 through 1995 were used. Birth weight-specific neonatal mortality rates among 2375 very low birth weight infants were estimated and analyzed by race and by level of perinatal services at the hospital of birth. Rates were compared with chi2 analysis. RESULTS Seventy-eight percent of very low birth weight deliveries occurred in level III hospitals. The overall neonatal mortality rate was 178 deaths/1000 very low birth weight live births. Neonatal mortality rates, adjusted for birth weight and race, were significantly higher (P < .05) for infants born in level I hospitals (267 deaths/1000 live births), all level II hospitals (232 deaths/1000 live births), and level II hospitals with neonatologists (213 deaths/1000 live births) than for infants born in level III centers (146 deaths/1000 live births). CONCLUSION Very low birth weight infants are more likely to survive if born in level III hospitals than in level I or II facilities, with or without neonatologists. Obstetric providers should support public health efforts and perinatal health systems to ensure that all women have access to a strong system of risk-appropriate perinatal care.

The clinical content of preconception care: women with chronic medical conditions.

This article reviews the medical conditions that are associated with adverse pregnancy outcomes for women and their offspring. We also present the degree to which specific preconception interventions and treatments can impact the effects of the condition on birth outcomes. Because avoiding, delaying, or achieving optimal timing of a pregnancy is often an important component of the preconception care of women with medical conditions, contraceptive considerations particular to the medical conditions are also presented.

Putting the “M” back in maternal–fetal medicine

Although maternal death remains rare in the United States, the rate has not decreased for 3 decades. The rate of severe maternal morbidity, a more prevalent problem, is also rising. Rise in maternal age, in rates of obesity, and in cesarean deliveries as well as more pregnant women with chronic medical conditions all contribute to maternal mortality and morbidity in the United States. We believe it is the responsibility of maternal-fetal medicine (MFM) subspecialists to lead a national effort to decrease maternal mortality and morbidity. In doing so, we hope to reestablish the vital role of MFM subspecialists to take the lead in the performance and coordination of care in complicated obstetrical cases. This article will summarize our initial recommendations to enhance MFM education and training, to establish national standards to improve maternal care and management, and to address critical research gaps in maternal medicine.

Fetal anomaly detection by second-trimester ultrasonography in a tertiary center

OBJECTIVE Our purpose was to determine the relative accuracy of indicated versus screening second-trimester ultrasonography for detection of fetal anomalies and to assess the cost effectiveness of anomaly screening. STUDY DESIGN The study population consisted of 2031 pregnant women with singleton gestations who prospectively underwent ultrasonographic scanning between 15 and 22 weeks and received complete obstetric care at the Medical University of South Carolina between July 1, 1993, and June 30, 1996. Patients were divided into two groups: (1) indicated and (2) screening. The cost of screening ultrasonography was compared with the cost of newborn care for selected anomalous fetuses. RESULTS Forty-seven fetuses (2.3%) were diagnosed by ultrasonography as having a major anomaly: 8.6% in the indicated group and 0.68% in the screening group (p=0.001). The sensitivity for detecting the anomalous fetus was 75.0% overall: 89.7% in the indicated group and 47.6% in the screening group (p=0.001). Of the 47 patients diagnosed with fetal anomalies, 11 (23.4%) chose pregnancy termination; of the 35 (74.5%) live-born anomalous infants, 29 (82.9%) were discharged alive. Projected newborn cost savings offset the cost of routine midtrimester screening. CONCLUSIONS Detection of anomalous fetuses was significantly better in the indicated compared with the screening group. Nevertheless, routine ultrasonographic screening appeared cost-effective in our population.

Levels of maternal care

In the 1970s, studies demonstrated that timely access to risk-appropriate neonatal and obstetric care could reduce perinatal mortality. Since the publication of the Toward Improving the Outcome of Pregnancy report, more than 3 decades ago, the conceptual framework of regionalization of care of the woman and the newborn has been gradually separated with recent focus almost entirely on the newborn. In this current document, maternal care refers to all aspects of antepartum, intrapartum, and postpartum care of the pregnant woman. The proposed classification system for levels of maternal care pertains to birth centers, basic care (level I), specialty care (level II), subspecialty care (level III), and regional perinatal health care centers (level IV). The goal of regionalized maternal care is for pregnant women at high risk to receive care in facilities that are prepared to provide the required level of specialized care, thereby reducing maternal morbidity and mortality in the United States.

A randomized clinical trial of prostaglandin E2 intracervical gel and a slow release vaginal pessary for preinduction cervical ripening

OBJECTIVE Our purpose was to compare the efficacy of 2 different prostaglandin E2 delivery methods for preinduction cervical ripening. STUDY DESIGN Ninety patients admitted for labor induction with a Bishop score <8 were randomized to either 0.5 mg prostaglandin E2 intracervical gel (Prepidil) every 6 hours for 2 doses or 10 mg prostaglandin E2 slow release vaginal pessary (Cervidil). Oxytocin induction was begun after 12 hours. It was estimated that enrollment of 90 women would be required to identify a 30% difference in the percent delivered in <24 hours (1 - beta = .80, alpha = .05). Data were analyzed with use of chi2 analysis or the Student t test. RESULTS There were 45 subjects in each treatment arm. The percent delivered by 24 hours was 53% with intracervical gel and 63% with vaginal pessary (P = .28). Mean change in Bishop score was 1.8 +/- 1.9 for the intracervical gel versus 3.2 +/- 3.1 for the vaginal pessary (P = .01). No difference was demonstrated in mean time to delivery, 28.3 versus 24.0 hours (P = .19) or percent requiring cesarean section. CONCLUSION Preinduction cervical ripening with a slow release prostaglandin E2 vaginal pessary resulted in greater change in Bishop score than with intracervical prostaglandin E2. There was a trend toward shorter time to delivery with the pessary. There was no statistically significant difference in percent delivered in <24 hours.

Executive summary of the reVITALize initiative: Standardizing obstetric data definitions

Precision in language has become critically important with the evolution of the electronic medical record and proliferation of measurement in vital statistics and health care. Taking the opportunity to standardize clinical definitions is a fundamental step in building a robust national data infrastructure that is useful and useable for clinicians and patients. The reVITALize Initiative leads and coordinates a national multidisciplinary movement to standardize obstetric data definitions for written and verbal clinical communication, electronic health record data capture, vital statistics and public health surveillance, measurement, quality improvement, reporting, and research.

The clinical content of preconception care: the use of medications and supplements among women of reproductive age

The use of prescription and over-the-counter medications and dietary supplements are common among women of reproductive age. For medications, little information about the teratogenic risks or safety is available, as pregnant women are traditionally excluded from clinical trials, and premarketing animal studies do not necessarily predict the effects of treatment in human pregnancy. Even less is typically known about the effects of dietary supplements on pregnancy outcomes, as they are not held to the same rigorous safety and efficacy standards as prescription medications. Congenital anomalies associated with medication use are potentially preventable, because they are linked with modifiable maternal exposures during the period of organogenesis. However, as women of reproductive age experience acute and chronic conditions that can result in adverse outcomes for the woman and her offspring, the benefits of use of a particular medication before or early in pregnancy may outweigh the risks. Resources and principles outlined in this article will aid healthcare providers in selecting appropriate medication regimens for women of reproductive age, particularly those with chronic health conditions, those who are planning a pregnancy, and those who may become pregnant.
