Experts as well agree that our health care system needs work. Common concerns are that the system does not reliably delivery high-quality care and that care is costly and often wasteful.
Is maternity care quality a problem in the United States?While everyone agrees that the U.S. health care system needs improvement, many assume that maternity care quality in the United States is very good. Is this correct?
One way to judge maternity care quality is to compare U.S. performance with other countries. A recent World Health Organization report identified 33 countries with lower maternal death rates than the United States, while 37 countries had lower newborn death rates, 40 had lower infant death rates, and 65 had lower rates of low birthweight. Thirty-two nations had higher rates of exclusive breastfeeding to at least six months (2010). The Organisation for Economic Co-operation and Development identified 24 high- and middle-income countries with lower cesarean rates in 2007 and just 4 with higher rates (2010). Despite this poor international ranking, the International Federation of Health Plans recently reported that average payments for vaginal birth in the U.S. were far higher than all other countries reported, including Canada, France, and Australia (2010).
Others have carefully examined the best available research on safe and effective care for mothers and babies. More and more rigorous systematic reviews clarifying the effects of maternity practices are available. Unfortunately, these reviews are rarely used to guide practice or policy. Many low-tech beneficial practices are underused, while invasive procedures are overused. The tendency in the United States to provide expensive, procedure-intensive maternity care without improving the health of women and babies has been called the "perinatal paradox: doing more and accomplishing less" (Rosenblatt 1989).
Optimal maternity care should follow the principle of "effective care with least harm." Instead, nearly all women who give birth in U.S. hospitals experience high rates of interventions, with risks of adverse effects. Procedures appropriate for a much smaller proportion of mothers, such as episiotomy and continuous electronic fetal monitoring, are common. Meanwhile, numerous beneficial practices that support women's own innate capacities or the "physiologic" process of childbirth, such as labor support and supportive care for breastfeeding, are underused.
As an expectant mother, and later as a new mother, you want the best quality of care for you and your baby. High-quality care will
We can define maternity care quality in the context of these six aims. Optimal maternity care will be:
Why do we need a comprehensive set of high-quality nationally recognized maternity care performance measures?Poor quality maternity care can lead to medical errors or to unnecessary interventions and complications, longer hospital stays, and infants needing intensive care services. These problems, in turn, increase costs and short- and long-term health problems in mothers and babies. With so many expectant mothers admitted to hospitals each year, maternity care quality affects many women, newborns and families.
Until recently, there has been little focus on quality measurement and reporting for maternity care. In 2008, the National Quality Forum (NQF) released important new tools for improving maternity care quality: a set of 17 national measures for assessing the quality of care from the end of pregnancy through facility care of women and newborns. (NQF is a national non-profit organization that helps set and achieve national priorities and goals for performance improvement, and endorses national consensus standards for measuring and publicly reporting on performance.) Most of the maternity care measures address care provided by hospitals and birth centers.
Nationally recognized maternity care performance measures will help improve maternity care quality by:
Measure developers, NQF, and others are working to refine and expand the original maternity care measure set. Measures are needed for the entire course of prenatal through postpartum care and for individual providers, provider groups, hospitals and birth centers, accountable care organizations, health plans, and states.
Rates of medical interventions during labor and birth, including labor induction, cesarean section, and episiotomy, vary widely from caregiver to caregiver, facility to facility, and place to place. The wide variation has little to do with differences in the needs or preferences of women. It primarily reflects differences in styles of practice, maternity markets and other factors that should not influence care. Your choice of caregiver and choice of where to give birth are major decisions that impact the kind of care that you experience during childbirth.
Many women wish to avoid routine, unneeded childbirth interventions. How can a woman find a caregiver and place of birth with, for example, relatively low episiotomy or cesarean rates? This type of information is increasingly collected and reported, and this website includes links to state-level maternity care performance websites.
Labor induction is another important example of an overused maternity practice. While induction is occasionally of value in certain circumstances, induction for convenience — the mother's convenience, the caregiver's convenience, or both — is increasingly common. Also, labor induction is being done for "reasons" that do not in fact improve health, such as "fetus seems large." Increased use of labor induction is leading to more babies born before they reach 40 weeks of gestation, even though the development of the fetus's brain, lungs, and other organs continues up to that time and babies born earlier are more likely to have problems. In addition, labor induction leads to an increased chance of c-section in first-time mothers and when a woman's cervix is not soft and ready to open.
Epidural analgesia is also used more widely than necessary. Mothers are given epidurals routinely as the "first line of defense" for labor pain. Not only is this routine use of epidural analgesia expensive, an epidural poses extra challenges for women and fetuses and can lead to use of many additional interventions. For example, this procedure can impair a woman's ability to move during labor, and later to push, decreasing the chance of a "spontaneous" vaginal birth with no vacuum extraction, forceps or cesarean. Using labor support, tubs, and other pain relief measures first, then moving to an epidural if needed, makes more sense for the health of mothers and babies.
The rate of cesarean section in the U.S. has been increasing steadily for more than a decade, and now reaches a new record level each year. Both the rate of "primary" or first-time cesareans and the rate of repeat cesareans are rising. Recent research reaffirms earlier World Health Organization guidance that optimal national cesarean rates are in the range of 5% to 10% of all births, while rates above 15% are likely to do more harm than good (Althabe and Belizán 2006). However, one woman in three now gives birth this way. Many factors contribute to this trend, and most are not related to the needs of women and newborns. Many women lack good information about the numerous risks of c-section for both mother and baby and the benefits of vaginal birth.
In many cases of medical intervention — including labor induction, epidural analgesia, and cesarean section — one intervention requires many others to monitor, prevent, or treat side effects of the first intervention. This "cascade of intervention" increases the risk of maternal or newborn harm and greatly increases costs.
For prenatal care, underused beneficial practices include prenatal vitamins, help with quitting smoking, breastfeeding support programs, and caregiver hands-to-belly movements to turn "breech presentation" fetuses to a head-first position before birth to avoid cesarean section.
Underused practices around the time of birth that can improve outcomes for mothers and babies include continuous labor support; use of tubs and other non-drug methods to help with labor pain; upright and side-lying positions for giving birth; delayed cord clamping; early mother-baby skin-to-skin contact; various measures to support breastfeeding; and counseling for women with postpartum depression.
For women who have had a previous cesarean section, a vaginal birth after cesarean (VBAC) is often the best option for birth, with the least chance of short and long term harm to mother and baby. Yet VBAC is underused and often unavailable. Many pregnant women who have had a previous cesarean section cannot find caregivers or hospitals offering VBAC as an option.
Maternity care providers other than obstetricians are also underused in this country. Best available research has shown that mothers who choose midwives as their lead maternity caregivers experience reduced likelihood of episiotomy, labor induction, electronic fetal monitoring, pain medications, forceps, artificially ruptured membranes, and low birthweight infants. Studies also show that women who choose midwives are more likely to be satisfied with their care. Yet fewer than 10% of women use midwives as their lead maternity caregivers.
The great majority of expectant mothers in the U.S. are healthy and at low risk for complications during childbirth. While much attention is given to the important needs of pregnant women with medical problems, or to those women who are at high risk of experiencing problems (about 1 in 6 pregnant women), we also need to ensure that healthy childbearing women receive high-quality care that is safe, effective, woman and family-centered, timely, efficient and equitable.
