A time to be born.

OBJECTIVES: This study used a large, population-based data set (n = 619,455) to establish reference standards of the timing of spontaneous vaginal births. METHODS: Low-risk births in Massachusetts from 1989 to 1995 were studied. This group comprised 242,276 births that met the following criteria: singleton, vertex, vaginal births with a birthweight of between 2500 and 4000 g; gestation between 37 and 42 weeks; a 5-minute Apgar score greater than 6, and no induction or stimulation. RESULTS: Low-risk births displayed a mild circadian pattern, with a peak between 11:00 AM and 1:00 PM and a trough between 11:00 PM and 1:00 AM. Subgroup analysis showed no clear differences except for parity. CONCLUSIONS: Reference standards should be developed and used as comparative norms for hospital and practice-based perinatal studies of diurnal patterns of birthing.

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.

Midwifery care and medical complications: the role of risk screening.

This study analyzed the 147,293 births attended by midwives in the United States in 1989. It used the revised and expanded standard national certificate of a live birth, which for the first time systematically records prenatal medical risk, intrapartum complications, obstetric procedures, and birth outcomes. It builds on earlier findings of positive outcomes for midwife-attended births to examine the prenatal medical risk profile of mothers served by midwives, the performance of obstetric procedures by midwives in different birth settings, more specific measures of outcomes, and possible explanations for these findings. Although midwives attending births in birth centers and homes generally serve mothers who are at much less than average medical risk, and in cases of intrapartum complications risk screening appears to occur, nurse-midwife-attended births in hospitals involve mothers whose risk profiles compare with, and in some cases are worse than, the national average. Nonetheless, the outcomes of these births are better than the national average. Mothers attended by midwives in birth centers and homes also have a different pattern of prenatal care, which begins later and includes fewer visits, but gives more apparent attention to self-care, and results in less smoking and alcohol use and greater weight gain.

A cross-national analysis of midwifery politics: six lessons for midwives.

Research based on interviews and analysis of documentary sources on the politics of midwifery in Canada, Denmark, the Netherlands, the UK and the US, suggests six political lessons for midwives and the organisations that represent them. The lessons are: general health reforms represent both an opportunity and a threat to midwives' status, and midwives must learn to communicate in ways policy makers understand; research matters; coalition building is essential; the media cares (a little); it is much easier to defend the status quo than create new policy; it is essential to clarify who is to be considered a midwife. A constant grass roots awareness of and involvement in a country's political and policy making process is seen as a necessity if midwives are to prosper as a profession.

The trials of Hanna Porn: the campaign to abolish midwifery in Massachusetts.

The case of Hanna Porn affords an opportunity to examine how the laws that led to the abolition of midwifery in Massachusetts evolved and were applied to the midwife whose case set the state legal precedent. Mrs Porn served primarily a Finnish-Swedish clientele of wives of laborers. The outcomes of the births she attended appear to have been positive, and she maintained a neonatal mortality rate of less than half that of local physicians. She also repeatedly defied court orders to stop practicing. Her case exemplifies the efforts that occurred nationally to abolish midwifery in the United States.

Where babies are born and who attends their births: findings from the revised 1989 United States Standard Certificate of Live Birth.

OBJECTIVE: To examine the results of changes in the birth certificate with regard to characteristics of the mothers and the birth weights of their infants. The United States Standard Certificate of Live Birth was revised in 1989 to include specific designations for the place of births out of hospital and the presence of a nurse-midwife or other midwife at the birth. METHODS: All results are based on data from the Natality, Marriage and Divorce Statistics Branch of the National Center for Health Statistics, Centers for Disease Control. In all cases reported here, the data represent at least 91% of all United States births in 1989. RESULTS: Different patterns of birth attendance emerged in different settings. In residential births, other midwives and "others" attended 66% of all births, whereas in freestanding birth centers, physicians and certified nurse-midwives attended 75.1% of all births. The characteristics of the mothers differed substantially according to who attended their births in these settings. Substantial interstate variations in place and attendant were also documented. CONCLUSION: The positive outcomes achieved in certain settings indicate a need for further research into the factors that influence birth outcomes.

The transformation of American midwifery: 1975 to 1988.

BACKGROUND: The use of midwives is a natural solution to the problem of improving access to skilled perinatal services while lowering costs. The number of midwife-attended births has grown from 0.9% of all births in 1975 to 3.4% of all births in 1988. The purpose of the study was to determine how mothers served by midwives and the settings in which they are served have changed in that period. METHODS: The analysis is based on birth certificate data from 1975 to 1988 from the Natality, Marriage and Divorce Statistics Branch of the National Center for Health Statistics, Centers for Disease Control. RESULTS: Almost all of the growth (93.2%) in midwife-attended births from 1975 to 1988 was in hospitals; 87.3% of all births attended by midwives occurred in hospitals. Pronounced differences exist between mothers served by midwives in and outside of hospitals, and there are strong regional patterns in midwife attendance at birth. CONCLUSIONS: Given the positive outcomes associated with midwifery practice, further research into the content of midwifery care is recommended.

Home birth in the United States, 1989-1992. A longitudinal descriptive report of national birth certificate data.

This study was conducted to profile home birth in the United States from 1989 to 1992 using two birth certificate data sources from the Natality Branch of the National Center for Health Statistics (NCHS). Analysis included published and unpublished descriptive tables about all U.S. home births from 1989 to 1992, and a subset of the 82,210 U.S. home births from 1989 to 1991 that were drawn from NCHS national birth certificate data tapes. Results indicated that less than one-third of reported home births were attended by nurse-midwives or physicians. Distinct regional patterns in the frequency of home births were observed, with higher concentrations in the southwestern and western states. When compared with the average childbearing woman in the United States, mothers who gave birth at home were more likely to be older, have fewer years of education, be married, and be white; they were also more likely to be of higher parity and to receive less prenatal care. Home birth mothers were less likely than average to smoke or drink alcohol prenatally, to have a prenatal medical risk condition or an obstetric complication, or to receive certain prenatal tests. The outcomes of newborns born at home compared favorably to the national average during the same period. Several findings varied considerably by race or ethnicity of the mother.

Population-based needs assessment. Bringing public health to midwifery practice.

Midwives are accustomed to individualizing their care of women on the basis of an assessment of each client's health status. By expanding their focus of care to encompass treatment of a population group, midwives and other providers can adopt a public health perspective through use of a community needs assessment. The first steps in diagnosing and treating the health problems of a group require the same rigorous and systematic examination of health indicators as does treatment of an individual. This article outlines the needs assessment process, identifies basic sources of information, and describes ways in which results can be presented.

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.

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.

State regulation, payment policies, and nurse-midwife services.

State regulatory and reimbursement policies continue to exert a strong influence on health workforce policy. Surveys conducted in 1991 and 1995 for the purpose of examining the impact of state regulation on the supply and practice of certified nurse-midwives (CNMs) showed that the single best predictor of the distribution and practice activities of CNMs was the degree to which state policies facilitated or restricted CNM practice.

Out-of-hospital births, U.S., 1978: birth weight and Apgar scores as measures of outcome.

An examination of 1978 natality data for the United States disclosed that low birth weight was less common among 30,819 infants born out of hospital than among 3,294,101 infants born in hospital in that year. When controls were applied for birth attendant, infants' race, and mothers' education, age, nativity, and parity, the data revealed that white, well-educated women between 25 and 39 years of age, who were having their second babies and were attended by midwives out of hospital, were at least risk of bearing low birth weight infants. The incidence rate of low birth weight babies was lower for midwife-attended births in every category examined. For college-educated white women, for example, the incidence rate was 2.0 percent among those attended by midwives, 4.6 percent among those giving birth in hospital, and 3.6 percent among those whose out-of-hospital deliveries were attended by physicians. Apgar scores for babies born both in and out of hospital were also studied but, because of inconsistent reporting, were given less attention. Excellent (9-10) Apgar scores were more common among babies born out of hospital than among those born in hospital (63 percent compared with 49 percent), particularly for out-of-hospital births attended by physicians. At least with respect to birth weight and Apgar scores, the claim that out-of-hospital births are inherently more dangerous than hospital births receives no support from these data. The findings also suggest the need for further refinement of vital statistics categories to permit the analysis of distinctions between births attended by certified nurse-midwives and those attended by lay midwives, as well as differences between births at home and those in alternative birth centers.
