Twelve years and more than 30,000 nurse-midwife-attended births: the Los Angeles County + University of Southern California women's hospital birth center experience

A midwifery-led in-hospital birth center within an academic medical center: successes and challenges

The University of California San Diego Community Women's Health Program (CWHP) has emerged as a successful and sustainable coexistence model of women's healthcare. The cornerstone of this midwifery practice is California's only in-hospital birth center. Located within the medical center, this unique and physically separate birth center has been the site for more than 4000 births. With 10% cesarean delivery and 98% breast-feeding rates, it is an exceptional example of low-intervention care. Integrating this previously freestanding birth center into an academic center has brought trials of mistrust and ineffectual communication. Education, consistent leadership, and development of multidisciplinary guidelines aided in overcoming these challenges. This collaborative model provides a structure in which residents learn to be respectful consultants and appreciate differences in medical practice. The CWHP and its Birth Center illustrates that through persistence and flexibility a collaborative model of maternity services can flourish and not only positively influence new families but also future generations of providers.

'The Best Health Care Delivery System in the World'? Women's health and maternity/newborn care trends in Philadelphia, PA, United States-1997-2011: a case report

Despite being ranked number one globally in terms of health care cost per capita, the United States (US) has ranked as low as 37th in the world in terms of health care system performance. This poor performance for one of the most developed nations in the world has been reflected in the underachieved attempts of the multiple US health care systems at improving maternal and newborn health, according to the goals set in 2000 by the United Nations with Millennium Development Goals (MDG's) 5: Improve Maternal Health, and 4: Reduce Child Mortality. This paper will examine the progress, or lack thereof, over a period of 15 years of the fifth largest urban area in the US - Philadelphia, Pennsylvania - in its delivery of health care to pregnant women and their newborns. Using data collected from national, state, and city health agencies, trends concerning pregnancy care will be presented and compared to the target goals of MDG-5 and MDG-4, as well as Healthy People 2020, a US government-based initiative to improve health care of all Americans. Findings will demonstrate that urban areas such as Philadelphia are on a path of not reaching goals that have been set by the United Nations and the US government, and by some indicators are moving away in a negative direction from these goals.

SCIENCE AND MIDWIFERY: PARADIGMS AND PARADOXES

The everyday world of clinical practice is filled with paradigms and paradoxes that stem from the issues of who defines knowledge, how it is generated, and how the individual midwife applies it when providing care for women and families. Research useful for clinical practice should provide evidence to support scientific approaches (models) or strategies (interventions) in caring for women. In a clinical discipline, the answers to research questions should eventually inform clinical decision-making by providing practical clinical knowledge. This article presents an application of Stevenson's research steps for the development of clinically applicable knowledge that the midwife can use to analyze and evaluate research findings as a basis for practice decisions. Specific examples of midwifery research are used to illustrate each stage in the process and the circular nature of knowledge development. The challenge is to prepare midwives who can apply research findings skillfully using the best evidence to support clinical practice, as well as to groom midwife researchers who will develop systematic programs of relevant research about midwifery practice and outcomes.

Midwifery Care of Poor and Vulnerable Women, 1925-2003

A systematic literature review of research on midwifery care of poor and vulnerable women from 1925 to 2003, which included topics studied, research methods used, and special issues and implications for future research, was performed; 44 studies published between 1955 and 2003 were identified. The majority were retrospective, descriptive studies. Outcomes examined included prenatal care visits, vaginal versus operative births, labor interventions, maternal and neonatal mortality and morbidity, birth weight, and cost-effectiveness. Studies showed that midwives predominantly serve vulnerable women who are young, poor, immigrants, or members of racial and ethnic minorities. Preterm birth prevention is emerging as a midwifery research focus. Health system changes are making it more difficult to provide effective care and counseling to disadvantaged women, especially in managed care settings. Extensive evidence documents excellent outcomes of midwifery care for the poor in urban and rural settings over the past three quarters of a century. Future research should include more intervention studies and use both qualitative and quantitative methods to investigate midwifery processes of care and the process-outcome connection. The research focus should broaden beyond childbirth to include gynecology, family planning, and primary care issues. Health disparities, cultural studies, obstetric interventions, and poor women's experiences of childbirth and midwifery care are important topics for future research.

Piercing the veil: The marginalization of midwives in the United States

This paper investigates the marginalization of certified nurse-midwives (CNMs) in the US. This marginalization occurs despite ample evidence demonstrating that a midwifery model delivers high-quality cost-effective care. Currently midwives attend only 7% of births, compared to 50-75% of births in other developed countries. Given the escalating costs of health care and relatively poor maternal and child health indicators in comparison with other developed countries, these findings are disturbing. This paper investigates this paradox through a qualitative case study of two prestigious but declining midwifery services in a large US city. Fifty-two multi-sited in-depth interviews were conducted along with an analysis of relevant archival sources. It was found that institutions successfully altered maternity care and diminished midwifery services without accountability for their actions. These findings illuminate the larger political-economic forces that shape the marginalization of midwifery in the US.

Resultados da assistência ao parto no Centro de Parto Normal Dr. David Capistrano da Costa Filho em Belo Horizonte, Minas Gerais, Brasil

A qualidade da assistência prestada em Centro de Parto Normal (CPN) por enfermeira obstetra é amplamente questionada. Foi realizado um estudo descritivo e retrospectivo de 2.117 partos ocorridos entre janeiro de 2002 e julho 2003, no CPN Dr. David Capistrano da Costa Filho, em Belo Horizonte. Entre os principais resultados da assistência, destacam-se a taxa de transferência materna com 11,4%; a taxa de cesárea com 2,2%; a taxa de admissão em Centro de Tratamento Intensivo (CTI) neonatal de 1,2%; e a taxa de Apgar < 7 no 5º minuto de 1%. Distocias de trabalho de parto e o desejo por analgesia peridural foram as maiores causas para a transferência materna, enquanto o distúrbio de desconforto respiratório foi a causa principal para admissão dos recém-nascidos no CTI. A mortalidade neonatal corrigida foi de 2 casos em mil nascidos vivos. Percebe-se que os resultados do CPN em estudo não diferem dos dados referidos na literatura internacional. A baixa taxa de cesárea é talvez o resultado mais evidente. Estudos comparativos nacionais são necessários.

Development of the Optimality Index as a New Approach to Evaluating Outcomes of Maternity Care

Evaluating perinatal outcomes within a framework of normalcy is a new focus of measurement. As maternal and child health clinicians and researchers look to evaluate care practices that are both of high quality and cost-effective, it is important to have measurement tools that assess differences among all women giving birth. The Optimality Index-US shifts the focus from rare adverse events to evidence-based optimal events. This article describes the continuing development of the index and discusses clinical implications for obstetric nurse clinicians.

Midwifery's research heritage: A Delphi survey of midwife scholars

A Delphi survey was conducted with midwife scholars to determine the top 10 midwifery studies worthy of recognition in 2005, the 50th anniversary of the American College of Nurse-Midwives (ACNM). This survey was undertaken by students of Philadelphia University's Graduate Midwifery Program as a service-learning project on behalf of the ACNM Division of Research. Selected midwife scholars participated in 2 or 3 rounds of response and feedback to achieve consensus about research deemed historically or currently important to midwifery practice. The top 10 studies, as determined by the 19 participating midwife scholars, are presented here. These results are offered as reflection on research that has helped to shape and define the discipline of midwifery in the United States.

From innovation to common practice: perinatal nursing pre-1970 to 2005

The history of perinatal nursing from before 1970 to the present is characterized by innovations that became common practice in later years. These innovations include fetal monitoring, mother/baby care, and early postpartum discharge. The driving forces behind changes in care within the social context of the times were scientific/medical developments and families' desires for the best possible childbearing experience. With innovations becoming commonplace, nursing practice became more complex. How nurses approach present-day challenges of increasing technology of birth, looming threats of litigation, and providing care under time and economic restraints is continuing to evolve.

Outcomes of high-risk women cared for by certified nurse-midwives

This study describes the incidence of specific high-risk factors of a population cared for by a group of certified nurse-midwives (CNMs) in a Mid-Atlantic, inner-city, nonprofit, hospital-based clinic. Outcomes were compared with all women who delivered in the United States in 1994. Univariate statistics, which consisted of descriptive statistics, frequencies, and percentage distribution, were used. This comparison suggests that CNMs can provide safe care to women with high-risk conditions. Outcomes for the midwifery sample were more favorable for vaginal births, vaginal deliveries after cesarean section, forceps- and vacuum-assisted deliveries, cesarean delivery, and 5-minute Apgar scores. The incidence of maternal fever and meconium stained amniotic fluid was higher. Implications and limitations of the study are discussed.

Measuring outcomes of midwifery care: development of an instrument to assess optimality

Research on the outcomes of midwifery care is hampered by the lack of appropriate instruments that measure both process and outcomes of care in lower risk women. This article describes an effort to adapt an existing measurement instrument focused on the optimal outcomes of care (The Optimality Index-US) to reflect the contemporary style of U.S.-based nurse-midwifery practice. Evidence for content validity of the instrument was derived from literature reports of randomized clinical trials, synthetic reviews, and the clinical consensus of professional reviewers. Eleven perinatal health professionals and consumers, representing disciplines of obstetrics and gynecology, midwifery, epidemiology, and neonatology reviewed the instrument. The instrument was then applied to an existing data set of women who intended to give birth at home (N = 1,286 women) to determine its utility in measuring events in the process and outcome of perinatal health care as managed by nurse-midwives. Results suggest that the tool holds promise for use in outcomes studies of U.S. perinatal care. Further testing of the instrument among diverse multicultural population groups, with various providers, and in diverse birth settings is warranted.

Nurse-midwifery: yesterday, today, and tomorrow

This article chronicles the dramatic changes in nurse-midwifery over the last 25 years. Presently, multiple models of midwifery education leading to certification exist, all within a competency-based framework. Accreditation of education programs and the certification process within nurse-midwifery remain examples to others. The consumer demand for certified nurse-midwives continues to rise, spurring the preparation for more professionals. However, the average woman in the United States still does not have access to a certified nurse-midwife/certified midwife for care. Several of the barriers to practice have been dismantled during the last quarter century; however, adequate reimbursement, relationships with various groups, and managed care are among the issues that will challenge midwifery in the new century.

Obstetric triage and advanced practice nursing

Obstetric triage is a rapidly growing area of obstetric care where most pregnancy complaints are evaluated starting at 20-24 weeks' gestation. This renewed interest in establishing obstetric triage units and using advanced practice nurses as care providers has heightened the visibility of obstetric triage for administrators and practitioners alike. This article reviews the history of obstetric triage, the role dimensions of advanced practice nurses in triage (specifically midwives), the increased clinical risks associated with obstetric triage, risk reduction strategies, and obstetric triage practice trends and liability issues in the future.

Women's experiences of transfer from a midwife-led to a consultant-led maternity unit in the UK during late pregnancy and labor

PURPOSE

This study explored the experiences of women who were transferred from a midwife-led to a distant consultant obstetric unit before or during labor.

BACKGROUND

Little attention is given to the psychological impact of transfer, particular when it takes place prior to labor.

METHOD

Narrative and progressively focused interviews were conducted with 18 women who faced or experienced transfer prior to or during labor. The data were analyzed using a grounded theory approach.

RESULTS

The core category in the transferred group was loss. This related to loss of choice, control, continuity, and support and was associated with anger and resentment. Distress appeared most common when transfer took place late in a healthy pregnancy when the mother recognized no risk to the baby.

CONCLUSIONS

More attention needs to be paid to the psychological impact of transfer from midwife-led to consultant-led care, particularly where this involves a change of location or midwife.

Midwifery care research: what questions are being asked? What lessons have been learned?

PURPOSE

To create and critically evaluate a research database about midwifery care that identifies topics studied, research methods, results, funding, publication data, and implications for a future midwifery research agenda.

METHODS

Systematic literature review. Studies included were 1) data-based research; 2) about midwifery care or practice; 3) in the United States; and 4) published between 1984-1998. The CINAHL and MEDLINE electronic databases were searched using a defined strategy, and relevant journals and bibliographies were searched by hand.

RESULTS

This 15-year review identified 140 studies of midwifery care published in 161 papers. A midwife was the lead author on 60%. Sixty percent were published in the Journal of Nurse-Midwifery. Six to 15 studies were published each year, and both the number of publications and funding increased over the time period. The six major areas of focus were: 1) midwifery management, 2) structure of care, 3) midwifery practice, 4) midwife-physician comparisons, 5) place of birth, and 6) care of vulnerable populations.

DISCUSSION

Although retrospective descriptive studies still predominate, more prospective studies, randomized controlled trials, multi-site studies, and quasi-experimental designs are being conducted. Qualitative methods are helping to measure nontraditional outcomes. A research agenda should be established based on discussion and debate within the profession. Midwife investigators need to build research teams and collaborate with other disciplines. Key areas for future research include alternative therapies, breastfeeding, cost-effectiveness, cultural studies, gynecology, health policy, menopause, postpartum care, substance abuse interventions, and the woman's experience of birth and midwifery care.

Midwifery care, social and medical risk factors, and birth outcomes in the USA

STUDY OBJECTIVE

To determine if there are significant differences in birth outcomes and survival for infants delivered by certified nurse midwives compared with those delivered by physicians, and whether these differences, if they exist, remain after controlling for sociodemographic and medical risk factors.

DESIGN

Logistic regression models were used to examine differences between certified nurse midwife and physician delivered births in infant, neonatal, and postneonatal mortality, and risk of low birthweight after controlling for a variety of social and medical risk factors. Ordinary least squares regression models were used to examine differences in mean birthweight after controlling for the same risk factors.

STUDY SETTING

United States.

PATIENTS

The study included all singleton, vaginal births at 35-43 weeks gestation delivered either by physicians or certified nurse midwives in the United States in 1991.

MAIN RESULTS

After controlling for social and medical risk factors, the risk of experiencing an infant death was 19% lower for certified nurse midwife attended than for physician attended births, the risk of neonatal mortality was 33% lower, and the risk of delivering a low birthweight infant 31% lower. Mean birthweight was 37 grams heavier for the certified nurse midwife attended than for physician attended births.

CONCLUSIONS

National data support the findings of previous local studies that certified nurse midwives have excellent birth outcomes. These findings are discussed in light of differences between certified nurse midwives and physicians in prenatal care and labour and delivery care practices. Certified nurse midwives provide a safe and viable alternative to maternity care in the United States, particularly for low to moderate risk women.

Characteristics of current hospital-sponsored and nonhospital birth centers

OBJECTIVES

(1) To describe contemporary birth centers in terms of the population served, organizational and financial characteristics, services provided, mission and philosophy, and planning and marketing techniques. (2) To compare hospital-sponsored and nonhospital models with regard to the above characteristics.

METHOD

Data from the National Survey of Women's Health Centers conducted in 1994 are analyzed using t-tests and chi-square tests.

RESULTS

Contemporary birth centers serve a diverse population of women and provide a range of clinical and nonclinical services. Birth centers are both hospital-sponsored and nonhospital, with the former growing at a faster rate. Compared to hospital-sponsored centers, nonhospital centers serve a larger proportion of uninsured women, provide a broader range of clinical services, and are more committed to women-centered care. Centers utilize different marketing methods and are involved in a number of organizational changes to better position themselves in the changing health care environment.

CONCLUSIONS

Birth centers offer an attractive option to consumers and are a viable model for delivering women-centered care. Given that all "birth center" facilities do not share the same philosophy and service mix, women need to have some assurance of what a "birth center" will, and will not, provide.

Cesarean delivery rates in women cared for by certified nurse-midwives in the United States: a review

The frequency of cesarean deliveries for women attended by certified nurse-midwives in the United States (1.8-10.4%) is lower than the rate for the general population of woman who gave birth in the United States in 1990 (23%). This paper describes the research that reported cesarean birth rates for certified nurse-midwives. Major methodology limitations of the research suggest that significant information gaps exist regarding nurse-midwifery care and its effect on cesarean delivery. Issues surrounding this common clinical procedure are complex, with its high cost and controversy over determinant factors. It is important to develop convincing evidence about the influence of nurse-midwives' care on reducing the frequency of cesarean delivery in the United States.
