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

Concerns in workforce development: linking certification and credentialing to outcomes

Investments in public health workforce development are based on the assumption that capacity and competencies are linked with the effectiveness and efficiency of providing essential public health services. However, evidence of the effects of workforce quantity or quality on the performance of core public health functions is limited. A review of public health, health care, and teacher education literature was conducted to determine the state of research in the field and to identify promising approaches and study designs for application to public health workforce training. A total of 861 articles and abstracts were reviewed from the health literature and 470 from teacher education literature. Sixty-five reports in the public health or health care literature and 68 in the education literature met the inclusion criteria. Eleven studies in public health or health literature reported positive correlations and 3 determined no substantial correlation to credentials. In the education literature, 10 studies reported a positive link, whereas 9 studies reported mixed or nonsignificant results. We conclude that a paucity of quality research or compelling evidence exists linking certification or credentialing to any related outcome. Until further research is conducted, discussions on the need for public health workforce certification and credentialing will be based on good-faith expectations for improving individual and organizational performance.

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.

A Hospital-Based Doula Program and Childbirth Outcomes in an Urban, Multicultural Setting

OBJECTIVES

The objective of this study is to determine whether there are differences in birth and breastfeeding outcomes for women who received labor support through a hospital-based doula program, compared with those who did not receive doula support in labor.

METHODS

We conducted a retrospective program evaluation to compare differences in birth outcomes between births at 37 weeks or greater with doula support and births at 37 weeks or greater without doula support through the first seven years of a hospital-based doula support program. Log-binomial regression models were used to compare differences in cesarean delivery rates, epidural use, operative vaginal delivery, Apgar scores, breastfeeding intent and early breastfeeding initiation after controlling for demographic and medical risk factors. The propensity score was included as an additional covariate in our regression model to minimize issues of selection bias. Analyses were conducted for the whole cohort of 11,471 women and by parity and provider service in subgroup analyses. Cochran-Mantel-Haenszel test was performed to detect differences in effects over time.

RESULTS

For the whole cohort, women with doula support had significantly higher rates of breastfeeding intent and early initiation. Subgroup analysis showed that having doula support was significantly related to: (a) higher rates of breastfeeding intent and early initiation rates for all women regardless of parity or provider with the exception of multiparous women with physician providers; (b) lower rates of cesarean deliveries for primiparous women with midwife providers.

CONCLUSION

A hospital-based doula support program is strongly related to improved breastfeeding outcomes in an urban, multicultural setting.

Dutch Women's Perceptions of Childbirth in the Netherlands

PURPOSE

To explore the lived experience of childbirth in Dutch women who had given birth at home in the Netherlands.

METHODS

Qualitative study using audiotaped interviews with 14 women.

RESULTS

Themes included the advantages of giving birth in the home, where the women felt more in control of their environment; the difficulty and normalcy of the pain associated with giving birth; the feelings of fulfillment and empowerment that come with childbirth and motherhood; and the importance of the supportive role of the midwife-caregiver.

NURSING IMPLICATIONS

Women in a culture different from that of the United States who gave birth at home felt fulfilled and empowered by the experience. These results can help U.S. nurses more fully understand the meaning of childbirth in a different culture and may help identify possible improvements in the design of care for women and newborns in the United States.

Finding midwifery in administrative data systems

Nurse-midwifery has accomplished remarkable clinical, policy, and political achievements using specially-collected data. Today, midwifery practice data can be found in existing administrative data systems: birth registration, hospital data depositories, and claims files. Issues in finding midwifery as practice and profession in these data systems are discussed. Improving the integrity of data that reveal midwives as caregivers should be a priority.

Disparity in prenatal care among women of colour in the USA

OBJECTIVE

To describe the disparity in prenatal care among women of colour in timing of initiation of prenatal care and total number of prenatal visits.

DESIGN

A retrospective, descriptive design.

SETTING

A large, urban university midwifery faculty practice.

PARTICIPANTS

439 healthy women at term (37-42 weeks gestation) with a vertex singleton pregnancy, and an essentially uncomplicated prenatal course. One clinic, the university facility, provided full-scope services. The other four community clinics, all outside the university in the larger metropolitan area, were designed to provide care to low-, under-, and uninsured pregnant women.

MEASUREMENTS

Timing of initiation of prenatal care and total number of prenatal visits were examined in relation to demographic variables, including race, education, age, marital status, method of payment and clinic sites.

FINDINGS

Significant differences in initiation of prenatal care and total number of prenatal visits were documented. The non-Hispanic white women at the university hospital clinic, with high school or college degrees and insurance or Medicaid, were more likely to visit prenatal clinics. Examination of association between timing of initiation of prenatal care and demographic variables showed significant differences in race and education.

KEY CONCLUSIONS

This study reflects the difficulty in access to care faced by women of colour. When comparing 1997 national survey findings with those of a 2001 study, about 40% of the 50 States and the District of Columbia showed an increase in the frequency of women receiving late care or no care; additionally, a disparity in access to prenatal care between non-Hispanic white and non-white women was noted in most of these areas.

IMPLICATIONS FOR PRACTICE

The number of births to women of colour delivered by midwives has rapidly increased in recent years. Also, the numbers of babies born to women of colour is anticipated to surpass 50% in the next few decades. Considering the increased proportion of births to women of colour, special attention to promote early prenatal care for these populations is needed. Recruitment and retention efforts for non-white midwives, regular education for cultural competence of midwives, and provision of culturally and linguistically appropriate care for women of colour should be considered.

Accuracy of birth certificate and hospital discharge data: a certified nurse-midwife and physician comparison

OBJECTIVES

Birth certificate and hospital discharge data are relied upon heavily for national surveillance and research on maternal health. Despite the great importance of these data sources, the recording accuracy in these datasets, comparing birth attendant type, has not been evaluated. The study objective was to assess the variation in chart documentation accuracy between certified nurse-midwives (CNMs) and physicians (MDs) for selected maternal variables using birth certificate and hospital discharge data.

METHODS

Data was obtained on women delivering in 10 Washington State hospitals that had both CNM and MD-attended births in 2000 (n = 2699). Using the hospital medical record as the gold standard of accuracy, the true positive rate (TPR) for selected maternal medical conditions, pregnancy complications, and intrapartum and postpartum events was calculated for CNMs and MDs using birth certificate data, hospital discharge data, and both data sources combined.

RESULTS

The magnitude of TPRs for most recorded maternal medical conditions, pregnancy complications, and intrapatum and postpartum events was higher for CNMs than for MDs. TPRs were significantly higher in birth certificate records for pregnancy-induced hypertension, premature rupture of membranes, labor augmentation, induction of labor, and vaginal birth after cesarean (VBAC) for CNM-attended births relative to MDs. Among combined data sources, CNM TPRs were significantly higher for pregnancy-induced hypertension and premature rupture of membranes.

CONCLUSIONS

CNMs had consistently higher accuracy of recorded maternal medical conditions, pregnancy complications, and intrapartum and postpartum events when compared to MDs for all data sources, with several being statistically significant. Our findings highlight discrepancies between CNM and MD hospital chart documentation, and suggest that epidemiologic researchers consider the issue of measurement error and birth attendant type.

Linking obstetric and midwifery practice with optimal outcomes

OBJECTIVE

To compare midwifery and medical care practices and measure optimal perinatal outcomes using a new clinimetric instrument.

DESIGN

Prospective descriptive cohort design.

SETTING

A large, inner city obstetric service with medical and midwifery services.

PARTICIPANTS

Three hundred seventy-five of 400 consecutively enrolled patients were participated (25 excluded due to extreme risk status or missing data); 92% were of minority race/ethnicity and 54% had less than a high school education. Of the 375 patients, 179 received physician care and 196 received nurse-midwife care.

MAIN OUTCOME MEASURES

The Optimality Index-US was measured. Health record data were extracted and scored using the Optimality Index-US to summarize the optimality of processes and outcomes of care as well as the woman's preexisting health status.

RESULTS

Midwifery patients had more optimal care processes (less use of technology and intervention) with no difference in neonatal outcomes, even when preexisting risk was taken into account.

CONCLUSION

Even among moderate-risk patients, the midwifery model of care with its limited use of interventions can produce outcomes equivalent to or better than those of the biomedical model.

A Concept Analysis of Optimality in Perinatal Health

This analysis was conducted to describe the concept of optimality and its appropriateness for perinatal health care. The concept was identified in 24 scientific disciplines. Across all disciplines, the universal definition of optimality is the robust, efficient, and cost-effective achievement of best possible outcomes within a rule-governed framework. Optimality, specifically defined for perinatal health care, is the maximal perinatal outcome with minimal intervention placed against the context of the woman's social, medical, and obstetric history.

[Socioeconomic inequalities in the provision and uptake of prenatal care]

OBJECTIVE

To describe socioeconomic inequalities in the provision and uptake of prenatal care among women in Barcelona (Spain) between 1994 and 2003.

METHODS

Cross-sectional study of women in Barcelona who delivered a child without birth defects. Information was obtained from hospital medical records and a personal interview with women included in the Barcelona Birth Defects Registry, containing a random sample of 2% of all pregnant women in the city (n = 2299).

DEPENDENT VARIABLES

number of obstetric visits, the trimester of the first visit, the number of obstetric ultrasound scans, the fifth-month diagnostic ultrasound scan, invasive procedures, prenatal folic acid intake, pregnancy planning, smoking and smoking cessation. The independent variables were maternal age and social class. Logistic regression models were filted for each dependent variable.

RESULTS

In social classes with manual occupations, there was a higher proportion of pregnant women who attended less than six obstetric visits and who attended the first obstetric visit after the first trimester. Moreover, these women were less likely to have undergone an invasive procedure, to have taken folic acid supplements, to have planned the pregnancy, to be non-smokers and to stop smoking. In the more privileged classes, there was a higher proportion of women who attended more than 12 obstetric visits and who underwent more than three ultrasound scans.

CONCLUSIONS

Socioeconomic inequalities were found in the provision and uptake of prenatal care in Barcelona. Uptake was greater in the more advantaged social classes but excessive medicalization was found in all classes. Rationalizing the use of healthcare resources and reducing excessive medicalization would reduce inequalities in prenatal care in Barcelona.

Prenatal care: limitations and opportunities

Prenatal care is a venerable tradition in the U.S. health care system and one that deserves critical examination. Inordinate amounts of public and personal resources are expended on a tradition of care that has not proven itself equal to current perinatal prevention challenges. In this article, the evolution of prenatal care is reviewed, its efficacy is critiqued, and efforts at restructuring the content and processes of care are examined. Three promising alternatives to the dominant medical model are described: the comprehensive prenatal care approach illustrated by many publicly funded prenatal clinics, the prenatal empowerment model as exemplified by midwifery care, and the prenatal group model as illustrated by CenteringPregnancy. Nurses are called upon to champion prenatal options for women.

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.

Assessment of quality of care in postpartum wards of Shaheed Beheshti Medical Science University hospitals, 2004

PURPOSE

Despite 77 per cent antenatal care coverage and 90 per cent skilled attendant at delivery, adjusted maternal mortality in Iran is 76 per 100,000 births. Low quality of maternal health services is one cause of maternal morbidity and mortality. However, few and limited studies have been devoted to the quality of postpartum care in Iran. This study aims to assess quality of care in postpartum wards of Shaheed Beheshti Medical Science University hospitals to show weakness and gaps areas in the care procedure for future improvement intervention programs. It is a descriptive study to assess quality of care in postpartum wards of Shaheed Beheshti Medical Science University hospitals, in 2003.

DESIGN/METHODOLOGY/APPROACH

Using quota sampling, 60 healthy women were recruited for the study. Data were collected using three forms including a questionnaire with demographic and obstetrics questions, a check-list for the postpartum care and education quality assessment. Control of vital signs, uterus assessment, perineum assessment, leaving bed, urinary system assessment, digestive system assessment, breast examination, extremities assessment, psychological assessment, as well as education about perineum self-care, breast-feeding, infant care, education before discharge and educational method. Validity and reliability of the questionnaire and checklist were assessed prior to use. Data were analyzed using SPSS.

FINDINGS

Results showed compatibility of provided postpartum care with the standards as follows: method of patient's education (52.68 per cent); control of vital signs (43.21 per cent); education about breast-feeding (26.06 per cent); care in getting out of bed (25.83 per cent); psychological care (19.36 per cent); urinary system assessment (16.66 per cent); education about perineum care (13.12 per cent); uterus assessment (10.6 per cent); digestive system assessment (9.69 per cent); patient's education before discharge (7.99 per cent); education about infant's care (7.81 per cent); perineum assessment (6.72 per cent); breast examination (1.11 per cent); and assessment of extremities (0.81 per cent). The study demonstrated that weak postpartum care was provided in 82 per cent of cases but also that mothers were satisfied with provided care in all domains of care. Mothers were very satisfied with facilities and less satisfied with personnel interaction with their visitors in hospital. There was no significant correlation between quality of services and clients' satisfaction (Spearman test, p < 0.05).

ORIGINALITY/VALUE

For the first time in Iran, this study has evaluated quality of care in postpartum wards of hospitals based on the defined standards. The study provided a defined standard for postpartum care, which is necessary for regular monitoring and evaluation and so evidence-based intervention programs to improve the system of care. It was also postulated that mothers' satisfaction with care is not always a good indicator of services quality.

Cesarean delivery in Native American women: are low rates explained by practices common to the Indian health service?

BACKGROUND

Studying populations with low cesarean delivery rates can identify strategies for reducing unnecessary cesareans in other patient populations. Native American women have among the lowest cesarean delivery rates of all United States populations, yet few studies have focused on Native Americans. The study purpose was to determine the rate and risk factors for cesarean delivery in a Native American population.

METHODS

We used a case-control design nested within a cohort of Native American live births, > or = 35 weeks of gestation (n = 789), occurring at an Indian Health Service hospital during 1996-1999. Data were abstracted from the labor and delivery logbook, the hospital's primary source of birth certificate data. Univariate and multivariate analyses examined demographic, prenatal, obstetric, intrapartum, and fetal factors associated with cesarean versus vaginal delivery.

RESULTS

The total cesarean rate was 9.6 percent (95% CI 7.2-12.0). Nulliparity, a medical diagnosis, malpresentation, induction, labor length > 12.1 hours, arrested labor, fetal distress, meconium, and gestations < 37 weeks were each significantly associated with cesarean delivery in unadjusted analyses. The final multivariate model included a significant interaction between induction and arrested labor (p < 0.001); the effect of arrested labor was far greater among induced (OR 161.9) than noninduced (OR 6.0) labors. Other factors significantly associated with cesarean delivery in the final logistic model were an obstetrician labor attendant (OR 2.4; p = 0.02) and presence of meconium (OR 2.3; p = 0.03).

CONCLUSIONS

Despite a higher prevalence of medical risk factors for cesarean delivery, the rate at this hospital was well below New Mexico (16.4%, all races) and national (21.2%, all races) cesarean rates for 1998. Medical and practice-related factors were the only observed independent correlates of cesarean delivery. Implementation of institutional and practitioner policies common to the Indian Health Service may reduce cesarean deliveries in other populations.

Reducing infant mortality rates using the perinatal periods of risk model

Despite decreases in the last 50 years, infant mortality rates in the United States remain higher than in other industrialized countries. Using overall infant mortality rates to determine the effectiveness of interventions does not help communities focus on particular underlying factors contributing to static, and sometimes increasing, community rates. This study was designed to determine and rank contributing factors to fetal-infant mortality in a specific community using the Perinatal Periods of Risk (PPOR) model. The PPOR model was used to map fetal-infant mortality for 1995 to 1998 in the Tulsa, Oklahoma, Healthy Start Program as compared to traditional calculation methods. The overall fetal-infant mortality rate using the PPOR model was 12.7 compared to 7.11 calculated using the traditional method. The maternal health cell rate was 5.4, maternal care cell rate was 2.9, newborn care cell was 1.9 compared to a 4.1 neonatal death rate calculated using the traditional method, and the infant health cell was 2.4 compared to a 2.9 postneonatal rate calculated using the traditional method. Because the highest infant mortality was in the maternal health cell, intervention strategies were designed to promote the health of women prior to and between pregnancies. The PPOR model was helpful in targeting interventions to reduce fetal-infant mortality based on the prioritization of contributing factors.

Midwifery at the crossroads in Estonia: attitudes of midwives and other key stakeholders

BACKGROUND

Since the initiation of health sector reforms in Estonia in 1992, the Baltic state has experienced a steep decline in the number of midwives and midwife graduates. At the same time, there has been a rapid increase, first in sexually transmitted infections and then in human immunodeficiency virus. The aim of this study was to draw on the perceptions of Estonia's midwives and other health care stakeholders to delineate the current situation of midwifery in the country, in the context of a sexually transmitted infection/human immunodeficiency virus epidemic.

MATERIALS AND METHODS

Data were obtained by sending a 32-question questionnaire, based on an agenda developed through semistructured interviews, to all midwives in Estonia. A nominal group technique was employed with key stakeholders to determine the extent of their agreement with the questionnaire's major findings.

RESULTS

The response rate to the questionnaire was 75%. There was no significant association between work satisfaction and independent variables of age, ethnicity, work abroad, increased responsibility, and involvement in postpartum care and counseling. There was, however, a significant association between work satisfaction and salary. The group process revealed that although there is no agreement on the role of family doctors and midwives in antenatal care, there is a general agreement that midwives should be more involved in postpartum care and that their tasks need to be better defined.

CONCLUSIONS

Almost half of the responding Estonian midwives are dissatisfied with their job, especially their salary. Increased responsibility for antenatal and postpartum counseling, with concurrent salary adjustments, may help stop the decline in the number of midwives, as could the opening up of new areas of work. A further reduction of the high abortion and sexually transmitted infection/human immunodeficiency virus rates is a critical challenge for Estonia, and midwives could be employed in services to do this, similar to their Nordic neighbors. Current indications suggest, however, that the number of midwives, especially new graduates, will continue to decline.

Advancing normal birth: organizations, goals, and research

In this column, the support for advancing normal birth is summarized, based on a comparison of the goals of Healthy People 2010, Lamaze International, the Coalition for Improving Maternity Services, and the midwifery model of care. Research abstracts are presented to provide evidence that the midwifery model of care safely and economically advances normal birth. Rates of intervention experienced, as reported in the Listening to Mothers survey, are compared to the forms of care recommended by the Cochrane Database of Systematic Reviews. Implications for perinatal education are addressed.

Down the Rabbit Hole

Care of the laboring woman and subsequent birth interventions have generally been based on tradition rather than a systematic examination of the cost-effectiveness of the interventions. This retrospective study examined the outcomes of nurse midwifery care at a large metropolitan university clinic setting. Findings suggest that more sensitive cost and quality indicators of nurse midwifery care need to be developed, and the effect of these on outcomes needs to be elucidated.

Vaginal birth after cesarean section: a pilot study of outcomes in women receiving midwifery care

A recent trend discouraging or not offering women a choice to labor after a cesarean birth has resulted in higher cesarean birth rates and lower rates of vaginal birth after cesarean birth (VBAC). The few studies describing midwifery practice have demonstrated favorable outcomes; however, the studies are too small to thoroughly evaluate critical outcomes. In this retrospective descriptive study, clinical outcome data were obtained from eight midwifery practices. The aims were to collect, aggregate, and analyze data from multiple midwifery practices and then describe outcomes. Usable data representing 649 trials of labor were submitted. Overall, 72% (range 64%-100%) of women gave birth vaginally. Mean infant birth weight was 3,501 (SD = 534) g, and the mean Apgar scores were 7.99 (SD = 1.4; median 8) at 1 minute and 8.84 (SD = 0.8; median 9) at 5 minutes. Only 5.3% (n = 14) of infants were admitted to the neonatal intensive care unit. This small retrospective study demonstrates similar outcomes to those reported in the current literature. A larger prospective study to carefully describe midwifery care outcomes using a common data collection method is needed to provide evidence for determining the continuation of VBAC as part of midwifery care.

The role of early newborn discharge legislation in influencing policy development: understanding the Kansas experience

Early newborn discharge legislation began a movement in health policy towards incremental changes in how medical consumers receive services. While well intentioned, these initiatives may undermine national efforts to address problems through more comprehensive reform, while stifling smaller efforts to address the problems locally. This paper discusses early newborn discharge legislation in Kansas: its origins, apparent impact, and implications. Findings from a hospital survey and two-year follow-up suggest a minimal effect of the legislation on health services in the state. Though acute hospital care appeared to replace home-based programs in many hospitals we spoke with, the more longstanding impact of the legislation seems to have been its precedent in how health policy is now made.

An exploratory metasynthesis of midwifery practice in the United States

OBJECTIVES

To conduct a metasynthesis of six qualitative studies of midwifery care and process; identify common themes and metaphors among the six studies for further exploration and theory development; and create a framework for further metasynthesis of qualitative studies of midwifery practice in the USA.

DESIGN

A qualitative metasynthesis to analyse, synthesise, and interpret six qualitative studies on the process and practice of midwifery care.

SAMPLE AND SETTING

Hospital, birth centre, and home birth settings were represented across all of the studies. Participants included nurse- and direct-entry midwives who provided both childbearing and gynaecological care. Recipients of midwifery care also received both childbearing and gynaecological care.

FINDINGS

Four overarching themes were identified: the midwife as an 'instrument' of care; the woman as a 'partner' in care; an 'alliance' between the woman and midwife; and the 'environment' of care. These were interpretively and conceptually arrayed into a helix model of midwifery care.

KEY CONCLUSIONS

The findings from this exploratory metasynthesis clearly indicate that the practice of midwifery is a dynamic partnership between the midwife and the woman, and reflects an environmental perspective. In a country that has a standard of highly technical childbirth care, perhaps the most outstanding concept of this model is that of the midwife as an 'instrument' of care. The significance of the findings will be determined by their ability to guide further research efforts to support a standard of midwifery care for all women in the USA.

IMPLICATIONS FOR PRACTICE

This model offers a benchmark and a structure for considering the dynamic elements of midwifery practice and key roles that the midwife plays in the health care of women and babies.

Home-birth emergencies in the US and Mexico: the trouble with transport

Proponents of the global Safe Motherhood Initiative stress that primary keys to safe home birth include transport to the hospital in cases of need and effective care on arrival. In this article, which is based on interviews with American direct-entry midwives and Mexican traditional midwives, I examine what happens when transport occurs, how the outcomes of prior transports affect future decision-making, and how the lessons derived from the transport experiences of birthing women and midwives in the US and Mexico could be translated into improvements in maternity care. My focus is on home birth in urban areas in Mexico and the US. In both countries, biomedicine and home-birth midwifery exist in separate cultural domains and are based on distinctively different knowledge systems. When a midwife transports a client to the hospital, she brings specific prior knowledge that can be vital to the mother's successful treatment by the hospital system. But the culture of biomedicine in general tends not to understand or recognize as valid the knowledge of midwifery. The tensions and dysfunctions that often result are displayed in midwives' transport stories, which I identify as a narrative genre and analyze to show how reproduction can go unnecessarily awry when domains of knowledge conflict and existing power structures ensure that only one kind of knowledge counts. This article describes: (1) disarticulations that occur when there is no correspondence of information or action between the midwife and the hospital staff; and (2) fractured articulations of biomedical and midwifery knowledge systems that result from partial and incomplete correspondences. These two kinds of disjuncture are contrasted with the smooth articulation of systems that results when mutual accommodation characterizes the interactions between midwife and medical personnel. The conclusion links these American and Mexican transport stories to their international context, describing how they index crosscultural markers, and suggest solutions, for "the trouble with transport."

Heterogeneity of Birthweight Outcomes among Latinas in Boston

This study examines the increase in poor birth outcomes, particularly low birthweight (LBW) and very low birthweight (VLBW) among Latinas in Boston for 1992–1994 and 1996. The research questions were: 1) What are the factors influencing Latino birth outcomes particularly LBW and VLBW?; and 2) Do these factors occur differently among Latino women from different ethnic backgrounds? Birth certificate data from the Massachusetts Department of Public Health for Latinos in Boston from 1987–1995 were used to examine these questions. The sociodemographic, health access, maternal/biological, substance abuse, and infant risk factors contributing to poor birthweight outcomes among Puerto Ricans, Cubans, Dominicans, Mexicans, Central Americans, South Americans, and other Latino ethnic groups were examined through bivariate and multivariate analyses. Statistically significant differences were observed among the groups. The findings reveal variation in the number and types of variables affecting birthweight among various Latino ethnic groups and inform health and social policies regarding Latino women's reproductive and perinatal health.

Women's public health policy in the 21st century

Midwives share a historic commitment with maternal and child public health (MCH) agencies to protect and improve perinatal health among vulnerable populations. Both professions are now beginning to broaden their responsibilities to include the comprehensive health needs of women. Because midwifery's unique woman-centered primary care practices reflect the goals and aims of the developing MCH women's health agenda, continued partnerships between midwives and the maternal and child public health community are imperative to promote the health of women and their families. To facilitate such collaboration, this article presents an overview of women's public health policy and articulates the unique contributions midwives can and do make to women's health care and public health policy.

The practice of nurse-midwifery in the era of managed care: reports from the field

OBJECTIVE

The purpose of this paper is to describe the reports of certified nurse-midwives (CNMs) about how changes in the financing and organization of health care in the late 1990s influenced their ability to serve vulnerable populations and provide a woman-centered, prevention-oriented midwifery model of care.

METHODS

A 13-page survey was mailed to all CNMs ever certified by the American College of Nurse-Midwives (N = 6365) in July 1998. The survey included closed- and open-ended questions. A total of 2405 CNMs responded: of these, 2089 were in clinical practice during the study period (1997-98) and 82% of the 2089 (N = 1704) wrote responses to the open-ended questions and were included in the qualitative database. We present responses to the closed-ended questions about seven domains of practice and elaborate on three major themes identified through content analysis of the qualitative data.

RESULTS

The majority (57%) reported that the changes in the larger health care environment had influenced their practices during 1997-98. The effects most frequently reported were 1) increased client loads (31%); 2) altered style of practice (30%): 3) inability to serve the same populations; (20%); 4) decreased client loads (20%); and 5) increased administrative duties (17%). Three major themes were identified and elaborated upon in the qualitative data: 1) challenges to the style of midwifery practice related to the managed care environment; 2) the loss of socially and economically at-risk women from CNMs' client base; and 3) barriers to high quality and comprehensive services for women.

CONCLUSIONS

During the late 1990s as managed care was expanding and health systems were merging, a significant number of CNMs in the field described threats to their ability to sustain economically viable practices and a style of care consistent with the woman-centered, prevention-oriented midwifery model.

La partera profesional: articulating identity and cultural space for a new kind of midwife in Mexico

This article documents the emergence of a new kind of midwife in Mexico, the thoroughly postmodern partera profesional. It traces the transnational conjunctures that facilitated her creation, illustrates aspects of her philosophy and praxis, and probes her ongoing articulations of identity. These women, who are of diverse sociocultural backgrounds, initially sought training from American direct-entry midwives in the independent out-of-hospital midwifery model; now, they are adapting that model to the situation in Mexico. Through their own practices, through intensive liaison work with traditional midwives, and through organizing national midwifery conferences and meetings, they are creating midwifery as both incipient profession and nascent social movement. Some of them operate outside the medical system while others are carving a niche within it. The mere existence of these self-consciously activist midwives constitutes a critique of monological Mexican medicine and its high cesarean rates; however, these women face a long struggle to define their identities, legalize their practices, and generate a sustainable space within the emergent Mexican technocracy. To their intense dismay, this struggle must take place within the context of the escalating disappearance of the traditional midwives whom they seek to support. The tension they feel between their desire to preserve traditional midwifery and their desire to create professional midwifery is a recurrent theme. These goals alternately complement and conflict with one another, yet both are central to the partera profesional's ongoing efforts at identity articulation.

Challenges and opportunities for nurse-midwives

This article reviews the major indicators of the growth in nurse-midwifery practice and education over the past 10 years. The major issues the profession has addressed are identified, as well as future challenges and opportunities. These challenges and opportunities are identified within the major dimensions of nurse-midwifery, that is, in practice, education, research, and within the public sector. The two major issues facing nurse-midwives are legislative initiatives related to the practice of nurse-midwives, such as reimbursement, and the mixed societal image of midwifery as a contemporary, cost-effective practice versus a peripheral activity by "old fashioned," informally educated individuals. The professional organization of nurse-midwives, the American College of Nurse-Midwives (ACNM), is addressing these issues through interdisciplinary and interorganizational legislative and marketing initiatives.

Serving women in need: nurse-midwifery practice in the United States

OBJECTIVE

Nurse-midwifery practices in the United States were examined to study the relationship between certified nurse-midwives' (CNMs) demographic, work setting, and practice characteristics in terms of clientele, practice size, and practice type. Factors that might influence the ability of CNMs to serve populations at risk for poor outcomes were given particular attention.

METHODOLOGY

A total of 2,405 responses to a 1998 mailed survey of 6,365 nurse-midwives ever-certified by the American College of Nurse-Midwives were analyzed.

RESULTS

Study results indicated that CNMs continue to serve a population who are, based on a social risk profile, disproportionately at risk for poor pregnancy outcomes, including women who are uninsured (16%), immigrant (27%), adolescent (29%), and women of color (50%). It was also found that clientele varied according to practice settings: CNMs working in non-hospital, nonprofit settings served a clientele that was 65% nonwhite, 44% immigrant, 40% adolescent, and 29% uninsured; these CNMs received 61% of their client payments from Medicaid. CNMs working in private offices or for managed care organizations were less likely to serve women with these characteristics.

CONCLUSION

Study results, taken in conjunction with research that documents the safety of nurse-midwifery practice, reinforce policy recommendations that support expanded access to nurse-midwifery services. Findings also indicate a need for further research in the areas of CNM workload and productivity in managed care settings and the association between CNM race and ethnicity and the race and ethnicity of their clients.

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.

Trusting women: essential to midwifery

Nonintervention in normal processes and promoting self-determination are both important aspects of midwifery philosophy and care; midwives are sometimes faced with situations in which these actually or potentially conflict. An example of this is epidural anesthesia, when the normal process of labor and birth may be affected by the woman's choices. This article focuses on an approach to this conflict that is essential to midwifery but often overlooked: the importance of trusting women to know what is best for themselves. The concept of trust in midwifery care is explored in depth, as a context from which to provide care, promote normal processes, ensure informed decision-making, empower women no matter what choices they make, and, when the woman's choice and midwife's philosophy differ, as a bridge from which to provide effective midwifery care.

Charges for maternity services: associations with provider type and payer source in a university teaching hospital

OBJECTIVES

Considerable evidence exists that payer status influences the type and cost of services provided. If payer status influences care, consumers may receive differential care secondary to presence and type of payer. This study examines the effect of payer status on certified nurse-midwives (CNMs) and obstetricians (OBs), correcting for methodologic problems that have been noted in previous studies.

METHODS/FINDINGS

Participants were 715 low-risk pregnant women seen in the CNM or OB practice in a university hospital service. All billed charges from the initial prenatal visit through two months postpartum were compared by payer. Charges by provider were also examined to determine the presence of differential payer effect. Unexpectedly, charges by payer did not show significant variance, nor did payer differently affect providers. Charges by provider type varied significantly, with CNMs having lower mean charges than OBs.

CONCLUSIONS

Differences in practice by payer source were not found for either provider group. This may reflect a lack of financial incentives to alter practice based on the payer, the homogeneity of the participants, or the large number of payers. The findings indicate that provider decision-making styles are likely due to non-payer factors in a system that lacks clear incentives to alter care patterns.

Does evidenced-based practice medicalise midwifery care? Part 2

In this paper evidence-based care is defined. The evidence to support the provision of care by midwives is presented, as is the evidence to support home birth for those women at low obstetric risk. In conclusion midwives are challenged to be political and use this evidence to support changes to improve the quality of care provided to women and their families.

Reduced risk of low weight births among indigent women receiving care from nurse-midwives

STUDY OBJECTIVE

To examine the effect of a comprehensive prenatal and delivery programme administered by nurse-midwives on the risk of low weight births among indigent women.

STUDY DESIGN

Historical prospective study. Birth outcomes among the cohort were compared with all county births during the same period, adjusting for maternal age and race. Results are expressed as relative risks with 95% confidence intervals.

SETTING

An enhanced Medicaid funded pre-natal programme administered by nurse-midwives from 1992 to 1994 in Westchester County, New York.

PARTICIPANTS

Indigent mothers (n = 1443), between the ages of 15 and 44, who were residents of Westchester County and indicated having Medicaid or no health care coverage.

RESULTS

There were 1474 live births among cohort mothers. Mean (SD) gestational age was 39.4 (1.9) weeks. Less than 6% of births occurred before 37 weeks gestation. The mean birth weight of cohort infants was 3365.6 (518.6) g. Only 4.1% of the cohort births were less than 2500 g. Compared with all county births, the cohort showed a 41% reduction in the risk of low weight births (RRlbw = 0.59, 95% CI: 0.46 to 0.73, p < .001) and a 56% reduction when compared with county Medicaid births only (RR = 0.44, 95% CI: 0.34 to 0.57, p < .005) adjusting for maternal age and race. Larger reductions were found for very low weight births.

CONCLUSIONS

Mothers need not be considered at high risk for adverse pregnancy outcomes based on their socioeconomic status alone. Moreover, a comprehensive prenatal programme administered by nurse-midwives may promote a reduction in adverse pregnancy outcomes among indigent mothers.

A comparison of visits and practices of nurse-midwives and obstetrician-gynecologists in ambulatory care settings

With more than 5 million patient visits annually, certified nurse-midwives (CNMs) substantially contribute to women's health care in the United States. The objective of this study was to describe ambulatory visits and practices of CNMs, and compare them with those of obstetrician-gynecologists (OB/GYNs). Sources of population-based data used to compare characteristics of provider visits were three national surveys of CNMs and two National Ambulatory Medical Care Surveys of physicians. When a subset of 4,305 visits to CNMs in 1991 and 1992 were compared to 5,473 visits to OB/GYNs in similar office-based ambulatory care settings in 1989 and 1990, it was found that a larger proportion of CNM visits were made by women who were publicly insured and below age 25. The majority of visits to CNMs were for maternity care; the majority of visits to OB/GYNs were for gynecologic and/or family planning concerns. Face-to-face visit time was longer for CNMs, and involved more client education or counseling. This population-based comparison suggests that CNMs and OB/GYNs provide ambulatory care for women with diverse demographic characteristics and differing clinical service needs. Enhancing collaborative practice could improve health care access for women, which would be especially beneficial for those who are underserved and vulnerable.

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.

A model of exemplary midwifery practice: results of a Delphi study

What is unique and exemplary about the midwifery model of care? Does exemplary midwifery care result in improved outcomes for the recipient(s) of that care? These are the questions that the profession of midwifery grapples with today within the context of a changing health care arena. Exemplary midwives, and women who had received their care, came to consensus about these issues in a Delphi study. A model of exemplary midwifery care is presented based on the identification of essential elements aligned within three dimensions: therapeutics, caring, and the profession of midwifery. Supporting the normalcy of pregnancy and birth, vigilance and attention to detail, and respecting the uniqueness of the woman, were several of many processes of care identified. The critical difference that emerged was the art of doing "nothing" well. By ensuring that normalcy continued through vigilant and attentive care, the midwives were content to foster the normal processes of labor and birth, intervening and using technology only when the individual situation required. Health care, whether in the gynecologic setting or during pregnancy, was geared to help the woman achieve a level of control of the process and outcome. The ultimate outcomes were optimal health in the given situation, and the experience of health care that is both respectful and empowering. The model provides structure for future research on the unique aspects of midwifery care to support its correlation with excellent outcomes and value in health care economics.

Identifying, evaluating and implementing cost-effective skill mix

BACKGROUND

The British National Health Service (NHS) employs a large number of individuals, at great monetary cost, to provide direct care to patients. Changes in the combinations of staff, including nurses, nurse practitioners and midwives, delivering this care have been shown to be effective in many settings.

FINDINGS

The (opportunity) cost implications of such changes in the skill mix are rarely evaluated adequately. The impact of releasing professionals' time has not been estimated and therefore determining whether changes are cost-effective is difficult; these difficulties have often been increased by poor study design.

CONCLUSIONS

Economic evaluation has been under-utilized in studies of skill mix. If economic evaluation demonstrates that skill mix changes reduce cost and improve or maintain patient outcomes, this is strong evidence that these changes should be implemented. Incentives may be required to attract the necessary personnel. This in itself may influence the cost of changing the skill mix and therefore the situation should be monitored as both costs and effectiveness can alter over time.

Characteristics of nurse-midwife patients and visits, 1991

OBJECTIVES

This study describes the patient populations served by and visits made to certified nurse-midwives (CNMs) in the United States.

METHODS

Prospective data on 16,729 visits were collected from 369 CNMs randomly selected from a 1991 population survey. Population estimates were derived from a multistage survey design with probability sampling.

RESULTS

We estimated that approximately 5.4 million visits were made to nearly 3000 CNMs nationwide in 1991. Most visits involved maternity care, although fully 20% were for care outside the maternity cycle. Patients considered vulnerable to poor access or outcomes made 7 of every 10 visits.

CONCLUSIONS

Nurse-midwives substantially contribute to the health care of women nationwide, especially for vulnerable populations.

Skill mix changes: substitution or service development?

An extensive review of published studies where doctors were replaced by other health professions demonstrates considerable scope for alterations in skill mix. However, the studies reported are often dated and have design deficiencies. In health services world-wide there is a policy focus which emphasises the substitution of nurses in particular for doctors. However, this substitution may not be real and increased roles for non-physician personnel may result in service development/enhancement rather than labour substitution. Further study of skill mix changes and whether non-physician personnel are being used as substitutes or complements for doctors is required urgently.
