Low-Interventional Approaches to Intrapartum Care: Hospital Variation in Practice and Associated Factors.

Despite evidence supporting the safety of low-interventional approaches to intrapartum care, defined by the American College of Obstetricians and Gynecologists as "practices that facilitate a physiologic labor process and minimize intervention," little is known about how frequently such practices are utilized. We examined hospital use of low-interventional practices, as well as variation in utilization across hospitals. Data came from 185 California hospitals completing a survey of intrapartum care, including 9 questions indicating use of low- versus high-interventional practices (eg, use of intermittent auscultation, nonpharmacologic pain relief, and admission of women in latent labor). We performed a group-based latent class analysis to identify distinct groups of hospitals exhibiting different levels of utilization on these 9 measures. Multivariable logistic regression identified institutional characteristics associated with a hospital's likelihood of using low-interventional practices. Procedure rates and patient outcomes were compared between the hospital groups using bivariate analysis. We identified 2 distinct groups of hospitals that tended to use low-interventional (n = 44, 23.8%) and high-interventional (n = 141, 76.2%) practices, respectively. Hospitals more likely to use low-interventional practices included those with midwife-led or physician-midwife collaborative labor management (adjusted odds ratio [aOR], 7.52; 95% CI, 2.53-22.37; P < .001) and those in rural locations (aOR, 3.73; 95% CI, 1.03-13.60; P = .04). Hospitals with a higher proportion of women covered by Medicaid or other safety-net programs were less likely to use low-interventional practices (aOR, 0.96; 95% CI, 0.93-0.99; P = .004), as were hospitals in counties with higher medical liability insurance premiums (aOR, 0.53; 95% CI, 0.33-0.85; P = .008). Hospitals in the low-intervention group had comparable rates of severe maternal and newborn morbidities but lower rates of cesarean birth and episiotomy compared with hospitals in the high-intervention group. Only one-quarter of hospitals used low-interventional practices. Attention to hospital culture of care, incorporating the midwifery model of care, and addressing medical-legal concerns may help promote utilization of low-interventional intrapartum practices.

Reducing Primary Cesareans: An Innovative Multipronged Approach to Supporting Physiologic Labor and Vaginal Birth.

Primary cesarean birth increases a woman's risk for hemorrhage, infection, pain, and cesarean births with subsequent pregnancies. A woman may experience difficulties with breastfeeding, bonding, and incorporating the newborn into the family structure. One urban, academic hospital in the Midwest participated in the American College of Nurse-Midwives Healthy Birth Initiative: Reducing Primary Cesarean Births Project. The project purpose was to reduce the rate of cesarean births in nulliparous, term, singleton, and vertex pregnancies. Strategies employed included use of intermittent auscultation, upright labor positioning, early labor lounge, one-to-one labor support, and team huddles. The baseline nulliparous, term, singleton, vertex cesarean rate in 2015 was 29.3%. In 2016, after 1 year of implementation of the project, the hospital decreased nulliparous, term, singleton, vertex cesarean rate to 26.1%-a reduction of 10%. In 2017, the rate was decreased to 25.3%-a reduction by 3.7%.

Implementation of Intermittent Auscultation for Low-Risk Women in Labor

The purpose of the program was to standardize use of intermittent auscultation (IA) for low-risk women who are in labor.

Reducing the Primary Cesarean Birth Rate: A Quality Improvement Project.

Research continues to support vaginal birth as the safest mode of childbirth, but despite this, cesarean birth has become the most common surgical procedure performed on women. The rate has increased 500% since the 1970s without a corresponding improvement in maternal or neonatal outcomes. A Colorado community hospital recognized that its primary cesarean birth rate was higher than national and state benchmark levels. To reduce this rate, the hospital collaborated with its largest maternity care provider group to implement a select number of physiologic birth practices and measure improvement in outcomes. Using a pre- and postprocess measure study design, the quality improvement project team identified and implemented 3 physiologic birth parameters over a 12-month period that have been shown to promote vaginal birth. These included reducing elective induction of labor in women less than 41 weeks' gestation; standardizing triage to admit women at greater than or equal to 4 cm dilation; and increasing the use of intermittent auscultation as opposed to continuous fetal monitoring for fetal surveillance. The team also calculated each obstetrician-gynecologist's primary cesarean birth rate monthly and delivered these rates to the providers. Outcomes showed that the provider group decreased its primary cesarean birth rate from 28.9% to 12.2% in the 12-month postprocess measure period. The 57.8% decrease is statistically significant (odds ratio [OR], 0.345; z = 6.52, P < .001; 95% confidence interval [CI], 0.249-0.479). While this quality improvement project cannot be translated to other settings, promotion of physiologic birth practices, along with audit and feedback, had a statistically significant impact on the primary cesarean birth rate for this provider group and, consequently, on the community hospital where they attend births.

In This Issue—The Winds of Change: The American College of Obstetricians and Gynecologists Recommends Limiting Interventions in Labor and Birth

ABSTRACTThe American College of Obstetricians and Gynecologists (ACOG) recent committee opinion, “Approaches to Limit Intervention During Labor and Birth,” reflects a shift in thinking that holds promise for sweeping changes in maternity care. This editorial puts the document in the context of the history of evidence-based maternity care and highlights the approaches suggested by ACOG including the use of intermittent auscultation, no routine amniotomy, or intravenous, delayed hospital admission, and freedom of movement throughout labor and birth. “Approaches to Limit Intervention During Labor and Birth” signals winds of change in maternity care.

An Exploration of the Views and Experiences of Midwives Using Intermittent Auscultation of the Fetal Heart in Labor

OBJECTIVES: To identify the experiences of midwives using intermittent auscultation of the fetal heart rate in labor.DESIGN: A qualitative descriptive study with a sample of 8 midwives, 3 from a DOMINO scheme and 5 from the labor ward at an Irish urban maternity unit. Data collection was through tape-recorded semistructured interviews. Data analysis involved transcription of the interviews verbatim and thematic analysis.FINDINGS: Three core themes were identified: vulnerability, the culture of the organization, and walking the tightrope. The findings suggest that the main challenges which inhibit midwives using intermittent auscultation is the lack of professional guidelines, inconsistency in documentation, and working in a biomedical model of care. The participants also identified that midwives practicing in a midwifery social model of care have more confidence and use midwifery skills to support the use of intermittent auscultation.CONCLUSIONS: The findings suggest working within a midwifery social model of care facilitates the use of intermittent auscultation. Guidelines and education on the explicit use of intermittent auscultation need to be made accessible to midwives. Midwives believed that women could promote the use of intermittent auscultation through their own education on monitoring fetal heart rate options in labor.

Putting intelligent structured intermittent auscultation (ISIA) into practice.

Fetal monitoring guidelines recommend intermittent auscultation for the monitoring of fetal wellbeing during labour for low-risk women. However, these guidelines are not being translated into practice and low-risk women birthing in institutional maternity units are increasingly exposed to continuous cardiotocographic monitoring, both on admission to hospital and during labour. When continuous fetal monitoring becomes routinised, midwives and obstetricians lose practical skills around intermittent auscultation. To support clinical practice and decision-making around auscultation modality, the intelligent structured intermittent auscultation (ISIA) framework was developed. The purpose of this discussion paper is to describe the application of intelligent structured intermittent auscultation in practice. The intelligent structured intermittent auscultation decision-making framework is a knowledge translation tool that supports the implementation of evidence into practice around the use of intermittent auscultation for fetal heart monitoring for low-risk women during labour. An understanding of the physiology of the materno-utero-placental unit and control of the fetal heart underpin the development of the framework. Intelligent structured intermittent auscultation provides midwives with a robust means of demonstrating their critical thinking and clinical reasoning and supports their understanding of normal physiological birth.

Intermittent Auscultation for Intrapartum Fetal Heart Rate Surveillance: American College of Nurse-Midwives.

Fetal heart rate surveillance is a standard component of intrapartum care. The fetal heart rate can be evaluated using intermittent auscultation or electronic fetal monitoring. Research that has compared these 2 strategies found them to be equivalent with respect to long-term neonatal outcomes. The purpose of this clinical bulletin by the American College of Nurse-Midwives is to review the evidence for use of intermittent auscultation and provide recommendations for intermittent auscultation technique, interpretation, and documentation.

The Use of Intermittent Auscultation in Parturients of Varying BMI Categories: Experience From a Mid-Sized Tertiary Care Obstetrical Unit.

The aim of this quality assurance project was to determine how many patients who qualified for intermittent auscultation (IA) in labour were actually monitored by intermittent auscultation. A secondary objective was to assess whether the rate of IA use depended on maternal BMI. We performed a retrospective chart review in a sample of women who received obstetrical care at Kingston General Hospital over one year from July 31, 2012. Eligibility was determined using the inclusion and exclusion criteria outlined by the hospital's guideline on intermittent auscultation. Two hundred seven of 244 charts analyzed in this review qualified for IA. The mean age of women in the study was 29.3 (range 17 to 41) years. Their mean gestational age was 39.6 (range 37 to 42) weeks. Fifty-six percent (116/207) of the eligible women actually had IA. Forty-seven percent of obese women who were eligible (47/100) had IA, compared with 64.4% of overweight women (58/90). This difference (17.4%) was statistically significant (P = 0.019, Fisher exact test). Fifty-six percent (116/207) of women with low risk pregnancies who were deemed eligible to have IA rather than electronic fetal heart rate monitoring actually had IA. Obese women were less likely to have IA than overweight women. More research is required regarding barriers to using IA in eligible women in our institution and elsewhere.

Intermittent auscultation of the fetal heart rate during labor: an opportunity for shared decision making.

Electronic fetal heart rate monitoring is the most common form of intrapartal fetal assessment in the United States. Intermittent auscultation of the fetal heart rate is an acceptable option for low-risk laboring women, yet it is underutilized in the hospital setting. Several expert organizations have proposed the use of intermittent auscultation as a means of promoting physiologic childbirth. Within a shared decision-making model, the low-risk pregnant woman should be presented with current evidence about options for fetal heart rate assessment during labor.

Consumer information on fetal heart rate monitoring during labor: a content analysis: a content analysis.

Electronic fetal monitoring (EFM) is used for the majority of births that occur in the United States. While there are indications for use of EFM for women with high-risk pregnancies, its use in low-risk pregnancies is less evidence-based. In low-risk women, the use of EFM is associated with an increased risk for cesarean birth compared with the use of intermittent auscultation of the fetal heart rate. The purpose of this investigation was to evaluate the existence of evidence-based information on fetal heart rate monitoring in popular consumer-focused maternity books and Web sites. Content analysis of information in consumer-oriented Web sites and books was completed using the NVivo software (QRSinternational, Melbourne, Australia). Themes identified included lack of clear terminology when discussing fetal monitoring, use of broad categories such as low risk and high risk, limited presentation of information about intermittent auscultation, and presentation of EFM as the standard of care, particularly upon admission into the labor unit. More than one-third of the sources did not mention auscultation, and conflicting information about monitoring methods was presented. The availability of accurate, publically accessible information offers consumers the opportunity to translate knowledge into the power to seek evidence-based care practices during their maternity care experience.

Care in a birth center according to the recommendations of the World Health Organization

Birth centers are maternal care models that use appropriate technology when providing care to birthing women. This descriptive study aimed to characterize intrapartum care in a freestanding birth center, in light of the practices recommended by the World Health Organization (WHO), with 1,079 assisted births from 2006 to 2009 in the Sapopemba Birth Center, São Paulo, Brazil. Results included the use of intermittent auscultation (mean=7 controls); maternal positions during delivery: semi-sitting (82.3%), side-lying (16.0%), other positions (1.7%), oral intake (95.6%); companionship (93.3%); exposure to up to three vaginal examinations (85.4%), shower bathing (84.0%), walking (68.0%), massage (60.1%), exercising with a Swiss ball (51.7%); amniotomy (53.4%), oxytocin use during the first (31.0%) and second stages of labor (25.8%), bath immersion (29.3%) and episiotomy (14.1%). In this birth center, care providers used practices recommended by the WHO, although some practices might have been applied less frequently.

Continuous Electronic Fetal Monitoring: Contradictions Between Practice and Research

The reliability, validity, and efficacy of electronic fetal monitoring (EFM) remain matters of controversy. In fact, several professional organizations, including the American College of Obstetricians and Gynecologists, have endorsed the use of intermittent auscultation for low-risk pregnant women. Nevertheless, in 1996, 83% of laboring women in the United States are monitored electronically. Nurses should encourage healthy, low-risk pregnant women to weigh carefully decisions about the use of EFM.
