Committee Opinion No. 687: Approaches to Limit Intervention During Labor and Birth

The First Baby Study: What women would like to have known about first childbirth. A mixed-methods study

BACKGROUND

Although prenatal care providers aim to prepare women for first childbirth, little research has explored retrospectively what birthing people would like to have known before first childbirth.

AIM

To describe women's reports of what they would like to have known before first childbirth but feel they were not told.

METHODS

This is a secondary analysis of the First Baby Study, a large prospective cohort study conducted in Pennsylvania, USA. Telephone interviews were conducted with 3006 women 1 month after their first childbirth. Women were first asked: "Was there anything that you would have liked to have known before your delivery that you were not told?". If "yes" they were asked a second question: "Please tell me what you would have liked to have known before your delivery".

ANALYSIS

A convergent mixed-methods analysis including descriptive analytics to compare characteristics of women by answers to the first question, and qualitative content analysis of women's open-ended answers to the second question.

FINDINGS

A total of 441 women (14.7%) reported there was something they would like to have known before their first childbirth. Women described that communication with care providers was their main concern. They would have liked a better understanding of their options before birth, more agency in decision-making, and more information about the topics of their body, their birth, their baby, and what to expect beyond birth.

CONCLUSIONS

Results highlight important topics for childbirth education, and the impact of gaps in shared decision-making, patient-provider communication, and supportive care practices for first childbirth, especially where women have identified vulnerabilities.

The effect of continuous electronic fetal monitoring on mode of delivery and neonatal outcome among low-risk laboring mothers at Debre Markos comprehensive specialized hospital, Northwest Ethiopia

Background

Electronic fetal heart rate monitoring (EFM) has been widely used in obstetric practice for over 40 years to improve perinatal outcomes. Its popularity is growing in Ethiopia and other sub-Saharan African countries to reduce high perinatal morbidity and mortality rates. However, its impact on delivery mode and perinatal outcomes in low-risk pregnancies remains controversial. This study aimed to assess the effect of continuous EFM on delivery mode and neonatal outcomes among low-risk laboring mothers at Debre Markos Comprehensive Specialized Hospital, Northwest Ethiopia.

Methods

A prospective follow-up study was conducted from November 20, 2023, to January 10, 2024. All low-risk laboring mothers meeting the inclusion criteria were included. Data were collected via pretested structured questionnaires and observation, then analyzed using Epi-data 4.6 and SPSS. The incidences of cesarean delivery and continuous EFM were compared using the chi-squared test and Fisher's exact test.

Results

The study found higher rates of instrumental-assisted vaginal delivery (7% vs. 2.4%) and cesarean sections (16% vs. 2%) due to unsettling fetal heart rate patterns in the continuous EFM group compared to the intermittent auscultation group. However, there were no differences in immediate neonatal outcomes between the groups.

Conclusion

When compared to intermittent auscultation with a Pinard fetoscope, the routine use of continuous EFM among low-risk laboring mothers was associated with an increased risk of cesarean sections and instrumental vaginal deliveries, without significantly improving immediate newborn outcomes. However, it is important to note that our study faced significant logistical constraints due to the limited availability of EFM devices, which influenced our ability to use EFM comprehensively. Given these limitations, we recommend avoiding the routine use of continuous EFM for low-risk laboring mothers to help reduce the rising number of operative deliveries, particularly cesarean sections. Our findings should be interpreted with caution, and further research with adequate resources is needed to draw definitive conclusions.

Optimizing the length of the second stage and management of pushing

Although the optimal length of the second stage of labor to minimize maternal and neonatal morbidities and optimize spontaneous vaginal delivery is not known, available evidence suggests that increasing length of the second stage is associated with increasing maternal and neonatal morbidity. Thus, evidence-based strategies to safely shorten the second stage, such as initiating pushing when complete dilation is reached among those with neuraxial anesthesia, is prudent. Many aspects of optimal management of the second stage of labor require future study to continue to guide clinical second-stage management.

Access, Interest, and Barriers to Incorporation of Birth Doula Care in the United States

Doula care improves maternal care, yet barriers exist to incorporating doula care. The purpose of this study was to evaluate interest and barriers to doula care. Overall, 508 women, 26-35 years of age (54.5%), White/Caucasian (89.8%), and married (88.6%), completed this study. Most reported ≥1 previous birth (97.6%). Respondents would "feel comfortable" (73.2%) and "more confident" (54.9%) with doula care at birth, and 57.9% reported their provider would be supportive of doula care. Only 39.0% expressed benefits to doula care during pregnancy compared to 72.6% at birth and 68.1% during postpartum. Most would hire a doula if health insurance covered some of the costs. Despite the recognized benefits and support of doula care, cost-associated barriers exist to the incorporation of doula care.

The impact of an intervention to improve intrapartum maternal vital sign monitoring and reduce alarm fatigue

BACKGROUND

The infrastructure of many labor and delivery units in the United States may dispose clinicians to overuse continuous and automated maternal physiological monitors. Overmonitoring low-risk patients can negatively affect patient care, primarily through generating alarm fatigue.

OBJECTIVE

Given the national attention to reducing alarm fatigue across healthcare settings and the concern for vital sign monitoring overuse on our labor and delivery unit, this quality improvement study aimed to evaluate vital sign monitoring patterns and alarm rates, and nursing experiences of alarm fatigue, before and after implementing a vital sign monitoring guideline for low-risk obstetrical patients.

STUDY DESIGN

This was a quality improvement study conducted on the labor and delivery unit of an urban, academic, tertiary hospital. The lack of guidance for maternal vital sign assessment in low-risk patients was identified as a potential safety challenge. A vital sign guideline was developed with multidisciplinary input, followed by a pre-post-implementation study evaluating vital sign volume and alarm rates. Total vital signs and alarm rates for all patients delivered during designated calendar days were assessed as a rate of vital signs per patient and compared across baseline, peri-intervention, and follow-up periods. Data were examined in p-type statistical process control charts and with time-series analysis. Patient characteristics and severe maternal morbidity, as a balancing metric, were compared across periods. Nursing perceptions of vital sign monitoring and experience of alarm fatigue were assessed via survey before and after implementation of the guideline.

RESULTS

A total of 35 individual 24-hour periods were evaluated with regard to vital sign and alarm volume. There was a decrease in vital signs per patient from a mean of 208.34 to 135.46 (incidence rate ratio, 0.65) and in alarms per patient from a mean of 14.31 to 10.51 (incidence rate ratio, 0.73) after implementation, with no difference in severe maternal morbidity. There were 85 total respondents to the nursing surveys, and comparison of modified task-load index scores before and after implementation demonstrated overall lower scores in the postperiod, although these were not statistically significant.

CONCLUSION

Introducing a maternal vital sign guideline for low-risk patients on the labor and delivery unit decreased vital signs measured as well as alarms, which may ultimately reduce alarm fatigue. This strategy should be considered on labor and delivery units widely to improve patient safety and optimize outcomes.

Guidelines for the management of urgent obstetric situations in emergency medicine, 2022

OBJECTIVE

To provide recommendations on the management of urgent obstetrical emergencies outside the maternity ward.

DESIGN

A group of 24 experts from the French Society of Emergency Medicine (SFMU), the French Society of Anaesthesia and Intensive Care Medicine (SFAR) and the French College of Gynaecologists and Obstetricians (CNGOF) was convened. Potential conflicts of interest were formally declared at the outset of the guideline development process, which was conducted independently of industry funding. The authors followed the GRADE (Grading of Recommendations Assessment, Development and Evaluation) method to assess the level of evidence in the literature. The potential drawbacks of strong recommendations in the presence of low-level evidence were highlighted. Some recommendations with an insufficient level of evidence were not graded.

METHODS

Eight areas were defined: imminent delivery, postpartum haemorrhage (prevention and management), threat of premature delivery, hypertensive disorders in pregnancy, trauma, imaging, cardiopulmonary arrest, and emergency obstetric training. For each field, the expert panel formulated questions according to the PICO model (population, intervention, comparison, outcomes) and an extensive literature search was conducted. Analysis of the literature and formulation of recommendations were conducted according to the GRADE method.

RESULTS

Fifteen recommendations on the management of obstetrical emergencies were issued by the SFMU/SFAR/CNGOF panel of experts, and 4 recommendations from formalised expert recommendations (RFE) established by the same societies were taken up to answer 4 PICO questions dealing with the pre-hospital context. After two rounds of voting and several amendments, strong agreement was reached for all the recommendations. For two questions (cardiopulmonary arrest and inter-hospital transfer), no recommendation could be made.

CONCLUSIONS

There was significant agreement among the experts on strong recommendations to improve practice in the management of urgent obstetric complications in emergency medicine.

Nonpharmacological labor pain management methods and risk of cesarean birth: A retrospective cohort study

BACKGROUND

Nonpharmacological labor pain management methods (NPLPMM) are noninvasive, low-cost practices that may play a role in reducing the rates of unnecessary cesarean birth. We aimed to evaluate whether the NPLPMM is associated with the mode of birth.

METHODS

We conducted a retrospective cohort study with clinical records of all women admitted for birth from January 2013 to December 2017. Records of women who had spontaneous labor or received induction or augmentation of labor during hospitalization were eligible for the study. We estimated the risk ratios for cesarean birth in general linear models using the Poisson regression with adjustments for the following variables: age, ethnicity, schooling, parity, gestational age, previous cesarean birth, spontaneous labor before admission, or induction/augmentation of labor.

RESULTS

Within the total of 3,391 medical records, 40.1% had the use of a nonpharmacological labor pain management method registered. Cesarean rate among the study population was 44.2%. The use of NPLPMM decreased the risk of cesarean birth by 78% (OR = 0.22; 95% CI 0.19-0.26). History of a previous cesarean birth (RR = 2.63; 95% CI 2.35-2.64), the lack of use of NPLPMM (RR = 2.46; 95% CI 2.22-2.72), and primiparity (RR = 2.09; 95% CI 1.86-2.34) were the strongest risk factors for cesarean birth in the cohort.

DISCUSSION

The use of NPLPMM may be an effective strategy to reduce unnecessary cesarean birth. Further studies to identify the efficacy of each method may help health professionals to offer more appropriate methods at different stages of labor.

Induction of labor or expectant management? Birth outcomes for nulliparous individuals choosing midwifery care

BACKGROUND

Induction of labor (IOL) has been studied as a strategy to reduce rates of cesarean birth (CB). Midwifery care models are also associated with lower CB rates, even considering that midwives perform fewer IOLs. In this study, we examined childbirth outcomes among individuals undergoing IOL in certified nurse-midwifery (CNM) care as compared to two categories of expectant management (EM).

METHODS

Data were from two CNM practices in the United States (2007-2018). The sample was limited to term nulliparous, nondiabetic, singleton, vertex pregnancies. Individuals having an IOL in each week of gestation (37th, 38th, etc) were compared with those having EM. Two methods for defining EM were considered as each method when used alone limits interpretation. Inclusive EM included all births starting in the same week as IOL. The exclusive EM group was comprised of all births occurring in the next gestational age week relative to the IOL cases (ie, 39th week IOL versus all births occurring at 40 weeks or later). Adjusted regression models were used to examine differences in CB by IOL versus EM (inclusive or exclusive) at each week of gestation.

RESULTS

Among 4057 CNM-attended pregnancies, the overall rate of IOL was 28.9% (95% CI 27.5%-30.3%) and CB was 19.4% (95% CI 18.1%-20.6%). Most IOLs involved obstetric indications. CB rates did not differ by IOL versus inclusive EM when performed between 37 and 40 weeks, though post hoc power calculations indicate these comparisons were low-powered. In multivarable models, IOL in the 40th week was associated with lower odds for CB versus exclusive EM definition (ie, births occurring at 41 0/7 weeks or later, OR (95% CI) = 0.57 (0.36-0.90)). This finding is explained by the large increase in CB rates after IOL during the 41st week (34.3%, up from 21.9% in the 40th week). Furthermore, the adjusted odds for CB in the 41st week were 55% higher relative to inclusive EM (all labors 41st week and later), OR (95% CI) = 1.55(1.11-2.15). Neonatal outcomes (aside from macrosomia) did not differ by IOL/EM at any gestational age.

DISCUSSION

Outcomes for nulliparous individuals having IOL or EM in the context of a midwifery model of care include low overall use of CB and low frequency of IOL before 41 weeks. In this model, IOL in the 40th week may lower CB odds, especially in comparison to those who do not have spontaneous labor and later undergo an IOL in the 41st week.

The trends and associated adverse maternal and perinatal outcomes of labour neuraxial analgesia among vaginal deliveries in China between 2012 and 2019: a real-world observational evidence

BACKGROUND

There is a lack of national report of the labour neuraxial analgesia (NA) rates in China in recent years, especially after the national promotion policy. The adverse maternal and perinatal outcomes associated with NA in China are also unknown. The aim of this study is to estimate the trends of NA rates from 2012 to 2019, to evaluate the effect of national policy on promoting NA and to identify the association between NA and adverse outcomes in China.

METHODS

We used the individual data from China's National Maternal Near Miss Surveillance System (NMNMSS) between 2012 and 2019, covering 438 hospitals from 326 urban districts or rural counties in 30 provinces across China. The analysis was restricted to singleton pregnant women who underwent vaginal delivery at or after 28 completed weeks of gestation. We estimate the trends of NA rates between 2012 and 2019, both at the national and provincial levels using Bayesian multilevel model. We also estimated the effect of the national pilot policy launched in 2018 using interrupted time-series analysis and identified the association between NA and adverse outcomes using modified Poisson regression combined with propensity score analysis.

RESULTS

Over the study period, 620,851 of 6,023,046 women underwent vaginal delivery with NA. The estimated national NA rates increased from 8.4% in 2012 to 16.7% in 2019. Most provinces experienced the same rapid rise during this period. The national pilot policy accelerated the rise of the rates. No differences were observed between women with NA and without any analgesia in the incidence of uterine atony, placental retention, intrapartum stillbirths and 1- and 5-min Apgar scores lower than 7. However, women with NA had higher incidences of genital tract trauma (adjusted relative risk (aRR) 1.53, 95% confidence interval (CI) 1.04-2.26) and maternal near miss (aRR 1.35, 95% CI 1.08-1.69), only in hospitals which were not covered by the national pilot policy and usually lack of sufficient equipment and personnel.

CONCLUSIONS

The national policy can effectively increase the NA rate. However, as genital tract trauma and maternal near miss may increase in low-resource hospitals, but not in high-resource hospitals, further study is required to identify the reasons.

Impact of therapeutic rest in early labor on perinatal outcomes: a prospective study

BACKGROUND

Pain and exhaustion in early labor are important to address, yet treatment options are limited. Therapeutic rest has existed for decades, although medication regimens and management strategies vary. In addition, there are little prospective data on perinatal outcomes and patient satisfaction to support and guide its use as an outpatient pain control option.

OBJECTIVE

This study aimed to evaluate whether outpatient therapeutic rest in early labor using intramuscular morphine sulfate and promethazine is associated with differences in perinatal outcomes and to assess patient satisfaction with this therapy.

STUDY DESIGN

This prospective cohort study was conducted at a tertiary care academic medical center from September 2017 to April 2020. Participants presenting to the hospital for labor evaluation were offered therapeutic rest if they met the following criteria: reassuring modified biophysical profile, cervical dilation of ≤5 cm without contraindications to vaginal delivery, and plan to discharge home after evaluation. The primary outcome was subsequent hospital admission in active labor, defined as cervical dilation of ≥6 cm. Secondary outcomes included hospitalization duration and perinatal outcomes. The outcomes between participants who accepted therapeutic rest and those who declined it were compared. All P values were calculated using the Fisher exact test, and multivariable regression was used to adjust for potential confounding baseline variables with P<.2. In addition, a prespecified sensitivity analysis was performed, limiting subjects to nulliparous participants. Furthermore, postpartum surveys were administered to a subset of women who received therapeutic rest.

RESULTS

Of the 82 individuals offered therapeutic rest and consented for the study, 66 (80%) accepted and 16 (20%) declined. Although the rate of active labor at admission to the labor and delivery unit in the treatment group was markedly higher (26% [17 of 66] vs 13% [2 of 16]), this difference was not statistically significant (P=.3) (adjusted relative risk, 1.87; 95% confidence interval, 0.44-7.89). Women who received therapeutic rest were less likely to require induction of labor compared with those who declined therapeutic rest (adjusted relative risk, 0.15; 95% confidence interval, 0.041-0.54). There was no difference between the groups in mode of delivery, epidural use, length of hospitalization, maternal complications, or adverse neonatal outcomes. These findings persisted in our prespecified sensitivity analysis, limiting the study to nulliparous participants. A subset (27 of 66 [40%]) of women were surveyed after receiving therapeutic rest, and all women (n=27) who were surveyed reported satisfaction.

CONCLUSION

There was no detectable difference in the primary outcome of active labor at admission between patients who accepted outpatient therapeutic rest and those who declined it. However, fewer participants in the treatment group eventually required induction of labor, and this group did not experience an increase in adverse perinatal outcomes. Among the participants surveyed, a high rate of treatment satisfaction was reported. This study suggested that therapeutic rest is a well-tolerated and effective option for outpatient pain control in early labor.

Defining arrest in the first and second stages of labor

Normal labor is identified as regular uterine contractions in addition to dilation and effacement of the cervix. It is necessary to define normal labor in order to delineate when a woman's labor pattern diverges from that observed in most women. Labor irregularities are subdivided into protraction disorders and arrest disorders. Identifying abnormal labor patterns and initiating appropriate interventions is essential because prolonged labor is associated with an increase in perinatal morbidity. The aim of this review was to delineate both normal labor progress and also discuss the current evidence-based diagnosis and treatment of protraction and arrest disorders. Many subtleties go into defining the boundaries of the first and second stages of labor. Historically, the Friedman curve established normal limits; but currently Zhang has advanced these definitions by accounting for current demographical characteristics and practice environments. The most significant variables for defining normal progress of labor are parity and regional anesthesia status. The most common causes of labor abnormalities are uterine inactivity, obesity, cephalopelvic disproportion and fetal malposition. Risks of extending the first and/or second stage of labor include postpartum hemorrhage, intraamniotic infection and potentially an increase in neonatal adverse outcomes. The management of labor disorders consists of oxytocin administration, amniotomy, intrauterine pressure catheter use and shared decision-making regarding proceeding with expectant management, operative vaginal delivery or cesarean delivery after weighing the risks and benefits of each option. The decision to extend the duration of labor is personalized for each mother-baby dyad and should be agreed upon depending on individual maternal and fetal circumstances.

Prospective cohort study of water immersion for labour and birth compared with standard care in an Irish maternity setting

OBJECTIVE

To examine the birth outcomes for women and babies following water immersion for labour only, or for labour and birth.

DESIGN

Prospective cohort study.

SETTING

Maternity hospital, Ireland, 2016-2019.

PARTICIPANTS

A cohort of 190 low-risk women who used water immersion; 100 gave birth in water and 90 laboured only in water. A control group of 190 low-risk women who received standard care.

METHODS

Logistic regression analyses examined associations between water immersion and birth outcomes adjusting for confounders. A validated Childbirth Experience Questionnaire was completed.

MAIN OUTCOME MEASURES

Perineal tears, obstetric anal sphincter injuries (OASI), postpartum haemorrhage (PPH), neonatal unit admissions (NNU), breastfeeding and birth experiences.

RESULTS

Compared with standard care, women who chose water immersion had no significant difference in perineal tears (71.4% vs 71.4%, adj OR 0.83; 95% CI 0.49 to 1.39) or in OASI (3.3% vs 3.8%, adj OR 0.91; 0.26-2.97). Women who chose water immersion were more likely to have a PPH ≥500 mL (10.5% vs 3.7%, adj OR 2.60; 95% CI 1.03 to 6.57), and to exclusively breastfeed at discharge (71.1% vs 45.8%, adj OR 2.59; 95% CI 1.66 to 4.05). There was no significant difference in NNU admissions (3.7% vs 3.2%, adj OR 1.06; 95% CI 0.33 to 3.42). Women who gave birth in water were no more likely than women who used water for labour only to require perineal suturing (64% vs 80.5%, adj OR 0.63; 95% CI 0.30 to 1.33), to experience OASI (3.0% vs 3.7%, adj OR 1.41; 95% CI 0.23 to 8.79) or PPH (8.0% vs 13.3%, adj OR 0.73; 95% CI 0.26 to 2.09). Women using water immersion reported more positive memories than women receiving standard care (p<0.01).

CONCLUSIONS

Women choosing water immersion for labour or birth were no more likely to experience adverse birth outcomes than women receiving standard care and rated their birth experiences more highly.

Intrapartum ultrasound at the initiation of the active second stage of labor predicts spontaneous vaginal delivery

BACKGROUND

Longer duration of active pushing during labor is associated with a higher rate of operative delivery and an increased risk of maternal and neonatal complications. Although immediate pushing at complete dilatation is associated with lower rates of chorioamnionitis and postpartum hemorrhage, it is also associated with a longer duration of pushing.

OBJECTIVE

This study aimed to evaluate whether fetal head station and position, as assessed by ultrasound at the beginning of the pushing process, can predict the mode of delivery and duration of pushing in nulliparous women.

STUDY DESIGN

This prospective observational study included nulliparous women with neuraxial analgesia and complete cervical dilatation. The following sonographic parameters were assessed just before the beginning of the pushing process, at rest, and while pushing during contraction: head position, angle of progression, head-perineum distance, and head-symphysis distance. The change between rest and pushing was designated as delta angle of progression, delta head-perineum distance, and delta head-symphysis distance. The sonographic measurements and fetal head station assessed by vaginal examination were compared between women who had a spontaneous vaginal delivery to those who underwent an operative delivery, and between those who pushed for more or less than 1 hour.

RESULTS

Of the 197 women included in this study, 166 (84.3%) had a spontaneous vaginal delivery, 31 (15.7%) had an operative delivery, 23 (11.6%) had a vacuum delivery, and 8 (4.0%) had a cesarean delivery. Spontaneous vaginal delivery and shorter duration of pushing (less than an hour) were significantly more common with a nonocciput posterior position (10.6% vs 47.3%; P<.005), a wider angle of progression, a shorter head-perineum distance and head-symphysis distance (both during rest and while pushing), and a lower fetal head station as assessed by digital vaginal examination. However, a logistic regression model revealed that only the angle of progression at rest and the delta angle of progression were independently associated with a spontaneous vaginal delivery with an area under the curve of 0.82 (95% confidence interval, 0.76-0.87; P<.0001) and 0.75 (95% confidence interval, 0.67-0.79; P<.0001), respectively.

CONCLUSION

Ultrasound performed at the beginning of the active second stage of labor can assist in predicting the mode of delivery and duration of pushing and perform better than the traditional digital examination, with the angle of progression at rest and delta angle of progression being the best predictors.

Is directed open-glottis pushing more effective than directed closed-glottis pushing during the second stage of labor? A pragmatic randomized trial - the EOLE study

OBJECTIVE

To compare the effectiveness of directed open-glottis and directed closed-glottis pushing.

DESIGN

Pragmatic, randomised, controlled, non-blinded superiority study.

SETTINGS

Four French hospitals between July 2015 and June 2017 (2 academic hospitals and 2 general hospitals).

PARTICIPANTS

250 women in labour who had undergone standardised training in the two types of pushing with a singleton fetus in cephalic presentation at term (≥37 weeks) were included by midwives and randomised; 125 were allocated to each group. The exclusion criteria were previous caesarean birth or fetal heart rate anomaly. Participants were randomised during labour, after a cervical dilation ≥ 7 cm.

INTERVENTIONS

In the intervention group, open-glottis pushing was defined as a prolonged exhalation contracting the abdominal muscles (pulling the stomach in) to help move the fetus down the birth canal. Closed-glottis pushing was defined as Valsalva pushing.

MEASUREMENTS

The principal outcome was "effectiveness of pushing" defined as a spontaneous birth without any episiotomy, second-, third-, or fourth-degree perineal lesion. The results in our intention-to-treat analysis are reported as crude relative risks (RR) with their 95% confidence intervals. A multivariable analysis was used to take the relevant prognostic and confounding factors into account and obtain an adjusted relative risk (aRR).

FINDINGS

In our intention-to-treat analysis, most characteristics were similar across groups including epidural analgesia (>95% in each group). The mean duration of the expulsion phase was longer among the open-glottis group (24.4 min ± 17.4 vs. 18.0 min ± 15.0, p=0.002). The two groups did not appear to differ in the effectiveness of their pushing (48.0% in the open-glottis group versus 55.2% in the closed-glottis group, for an adjusted relative risk (aRR) of 0.92, 95% confidence interval (CI) 0.74-1.14) or in their risk of instrumental birth (aRR 0.97, 95%CI 0.85-1.10).

KEY CONCLUSIONS

In maternity units with a high rate of epidural analgesia, the effectiveness of the type of directed pushing does not appear to differ between the open- and closed-glottis groups.

IMPLICATIONS FOR PRACTICE

If directed pushing is necessary, women should be able to choose the type of directed pushing they prefer to use during birth. Professionals must therefore be trained in both types so that they can adequately support women as they give birth.

General methods for measuring and comparing medical interventions in childbirth: a framework

Background

The continue increase of interventions during labour in low risk population is a controversial issue of the current obstetric literature, given the lack of evidence demonstrating the benefits of unnecessary interventions for women or infants’ health. This makes it important to have approaches to assess the burden of all medical interventions performed.

Methods

Exploiting the nature of childbirth intervention as a staged process, we proposed graphic representations allowing to generate alternative formulas for the simplest measures of the intervention intensity namely, the overall and type-specific treatment ratios. We applied the approach to quantify the change in interventions following a protocol termed Comprehensive Management (CM), using data from Robson classification, collected in a prospective longitudinal cohort study carried out at the Obstetric Unit of the Cà Granda Niguarda Hospital in Milan, Italy.

Results

Following CM a substantial reduction was observed in the Overall Treatment Ratio, as well as in the ratios for augmentation (amniotomy and synthetic oxytocin use) and for caesarean section ratio, without any increase in neonatal and maternal adverse outcomes. The key component of this reduction was the dramatic decline in the proportion of women progressing to augmentation, which resulted not only the most practiced intervention, but also the main door towards further treatments.

Conclusions

The proposed framework, once combined with Robson Classification, provides useful tools to make medical interventions performed during childbirth quantitatively measurable and comparable. The framework allowed to identifying the key components of interventions reduction following CM. In its turn, CM proved useful to reduce the number of medical interventions carried out during childbirth, without worsening neonatal and maternal outcomes.

The Experience of Land and Water Birth Within the American Association of Birth Centers Perinatal Data Registry, 2012-2017

Consumer demand for water birth has grown within an environment of professional controversy. Access to nonpharmacologic pain relief through water immersion is limited within hospital settings across the United States due to concerns over safety. The study is a secondary analysis of prospective observational Perinatal Data Registry (PDR) used by American Association of Birth Center members (AABC PDR). All births occurring between 2012 and 2017 in the community setting (home and birth center) were included in the analysis. Descriptive, correlational, and relative risk statistics were used to compare maternal and neonatal outcomes. Of 26 684 women, those giving birth in water had more favorable outcomes including fewer prolonged first- or second-stage labors, fetal heart rate abnormalities, shoulder dystocias, genital lacerations, episiotomies, hemorrhage, or postpartum transfers. Cord avulsion occurred rarely, but it was more common among water births. Newborns born in water were less likely to require transfer to a higher level of care, be admitted to a neonatal intensive care unit, or experience respiratory complication. Among childbearing women of low medical risk, personal preference should drive utilization of nonpharmacologic care practices including water birth. Both land and water births have similar good outcomes within the community setting.

The Birth Education Starts Today Video on Birth Care Options: Evaluation With University Students

Despite evidence indicating that midwife-attended birth is safe and satisfactory, few U.S. families have credentialed midwives as their birth care providers. In the context of person-centered health care and improving maternity care, we evaluated how an author-constructed video featuring evidence and personal narratives on midwifery care affected attitudes and care preferences/intentions for a hypothetical future birth among university students who had not become parents. Students (114 women, 30 men) completed care attitude and preference items before and after viewing the video. Significant (p < .001) changes indicated significantly improved attitudes toward midwives and out-of-hospital birth and related preferences. We discuss the educational framework of the video and plans to determine whether short-term effects translate into care-seeking behavior across diverse populations.

Delivery mode is associated with maternal mental health following childbirth

Childbirth is a life-transforming event often followed by a time of heightened psychological vulnerability in the mother. There is a growing recognition of the importance of obstetrics aspects in maternal well-being with the way of labor potentially influencing psychological adjustment following parturition or failure thereof. Empirical scrutiny on the association between mode of delivery and postpartum well-being remains limited. We studied 685 women who were on average 3 months following childbirth and collected information concerning mode of delivery and pre- and postpartum mental health. Analysis of variance revealed that women who had cesarean section or vaginal instrumental delivery had higher somatization, obsessive compulsive, depression, and anxiety symptom levels than those who had natural or vaginal delivery as well as overall general distress, controlling for premorbid mental health, maternal age, education, primiparity, and medical complication in newborn. Women who underwent unplanned cesarean also had higher levels of childbirth-related PTSD symptoms excluding those with vaginal instrumental. The risk for endorsing psychiatric symptoms reflecting clinically relevant cases increased by twofold following unplanned cesarean and was threefold for probable childbirth-related PTSD. Maternal well-being following childbirth is associated with the experienced mode of delivery. Increasing awareness in routine care of the implications of operative delivery and obstetric interventions in delivery on a woman's mental health is needed. Screening at-risk women could improve the quality of care and prevent enduring symptoms. Research is warranted on the psychological and biological factors implicated in the mode of delivery and their role in postpartum adjustment.

Describing latent phase duration and associated characteristics among 1281 low-risk women in spontaneous labor

BACKGROUND

Recent research suggests that latent phase of labor may terminate at 6 rather than 4 centimeters of cervical dilation. The objectives of this study were to: (a) characterize duration of the latent phase of labor among term, low-risk, United States women in spontaneous labor using the women's self-identified onset; and (b) quantify associations between demographic and maternal/newborn health characteristics and the duration of the latent phase.

METHODS

This prospective study (n = 1281) described the duration of the latent phase of labor in hours, stratified by parity at the mean, median, and 80th, 90th, and 95th percentiles. The duration of the latent phase was compared for each characteristic using t tests or Wilcoxon rank-sum tests and regression models that controlled for confounders.

RESULTS

In this sample of predominantly white, healthy women, duration of the latent phase of labor was longer than described in previous studies: The median duration was 9.0 hours and mean duration was 11.8 hours in nulliparous women. The median duration was 6.8 hours and mean duration was 9.3 hours in multiparous women. Among nulliparous women, longer duration was seen in women whose fetus was in a malposition. Among multiparous women, longer durations were noted in women with chorioamnionitis and those who gave birth between 41 and 41 + 6 weeks' gestation (vs between 40 and 40 + 6 weeks' gestation).

CONCLUSIONS

The latent phase of labor may be longer than previously estimated. Contemporary estimates of latent phase of labor duration will help women and providers accurately anticipate, prepare, and cope during spontaneous labor.

Promoting active labor admission: Early labor lounge implementation barriers and facilitators from the clinician perspective

BACKGROUND

The cesarean birth rate for low-risk pregnant individuals in the United States exceeds the recommended Healthy People 2020 rate. One recommended strategy to reduce cesarean in this population is delaying hospital admission until active labor commences. A quality improvement program was implemented at a community hospital using the early labor lounge (ELL) to promote admission in active labor. This study focuses on identifying the barriers and facilitators from the clinician perspective to implementing the ELL.

METHODS

Interviews were conducted with a purposive sample of clinicians. Interview transcripts were open coded and themes identified inductively. A framework analysis was then conducted using the Consolidated Framework for Implementation Research (CFIR).

RESULTS

Twenty-five staff members participated. Barriers and facilitators were identified in four of the CFIR domains. Facilitators included the strength of the evidence and the ELL itself, including the tools it contained for supporting women in latent labor. Barriers to implementation included clinician self-efficacy and perceived low usage of the ELL.

CONCLUSION

This analysis using, CFIR identified several barriers and facilitators to the implementation of the ELL. The context of the individual woman presenting in triage and the acceptability and self-efficacy of the individual clinicians represented important factors for implementation.

Draft Opioid-Prescribing Guidelines for Uncomplicated Normal Spontaneous Vaginal Birth

Women who experience an uncomplicated vaginal delivery have acute intrapartum pain and variable pain in the immediate postpartum period. Although the Centers for Disease Control and Prevention (CDC) has urged clinicians to improve opioid-prescribing behavior, there are no published clinical practice guidelines for prescribing opioids during labor and delivery and at discharge for patients with uncomplicated normal spontaneous vaginal delivery. To address the knowledge gap regarding guidelines for pain management in this population, we used the national Premiere Health Care Database for deliveries of uncomplicated vaginal births from January 1, 2014, to December 31, 2016, to determine the prevalence of opioid administration. Among the 49,133 women who met inclusion criteria, 78.2% were administered opioids during hospitalization and 29.8% were administered opioids on the day of discharge. Descriptive statistics were generated to document the characteristics of the patients receiving opioids as well as the characteristics of hospitals administering opioids during inpatient labor and delivery and on discharge. Patient-level variables included age group, marital status, race, ethnicity, payer type, and length of stay. Hospital-level variables included bed size, geographic region, teaching status, and urbanicity status. These data were then presented in an electronic Delphi survey to 14 participants. The survey participants were obstetrician-gynecologists identified by the American College of Obstetricians and Gynecologists as being thought leaders in the obstetrics field and who had also demonstrated an active interest in the opioid epidemic and its effect on women's health. After the panelists viewed the opioid administration data, they were presented with an adapted version of the CDC's guidelines for opioid prescribing for chronic pain management. The eight adapted guidelines were constructed to be more relevant and appropriate for the inpatient normal spontaneous vaginal delivery population. After three rounds of the surveying process, seven of the eight adapted guidelines were endorsed by the survey participants. These seven draft consensus guidelines could now be used as a starting point to develop more broadly endorsed and studied guidelines for appropriately managing pain control for women with uncomplicated spontaneous vaginal birth.

Pro-Con Debate: Nitrous Oxide for Labor Analgesia

This Pro-Con debate will provide the practitioner with an evidence-based knowledge approach to assist the clinician in determining whether to employ (Pro) or not to employ (Con) this technique in the obstetrical suite for labor analgesia. Nitrous oxide has been used safely in dentistry and medicine for many centuries. However, accumulating preclinical and clinical evidence increasingly suggests previously unrecognized adverse maternal and fetal effects of nitrous oxide, which warrants reconsideration of its use in pregnant women and a more detailed informed consent. Nitrous oxide is associated with metabolic, oxidative, genotoxic, and transgenerational epigenetic effects in animals and humans that may warrant limiting its usefulness in labor. This debate will discuss and review the clinical uses, advantages, and disadvantages of nitrous oxide on occupational effects of nitrous oxide exposure, neuroapoptosis, FDA warning on inhalational anesthetics and the developing brain, research limitations, occupational exposure safety limits, effects on global warming, and potential for diversion.

The ARRIVE Trial: Interpretation from an Epidemiologic Perspective

The findings of the ARRIVE trial (A Randomized Trial of Induction Versus Expectant Management) were recently published. This multisite randomized trial was designed to provide evidence regarding whether labor induction or expectant management is associated with increased adverse perinatal outcomes and risk of cesarean birth among healthy nulliparous women at term. The trial reported that the primary outcome, a composite of adverse neonatal outcomes, was not significantly different between the 2 groups; the principal secondary outcome, cesarean birth, was significantly more common among women whose pregnancy was expectantly managed than among women whose labor was induced at 39 weeks. These results have the potential to change existing practice. Several aspects of the study design may influence its potential internal and external validity and should be considered in order to make sound causal inferences from this trial, which will in turn affect how its findings are translated to practice. Although chance and confounding are of minimal concern, given the sample size and randomization used in the study, selection bias may be a concern. Studies are vulnerable to selection bias when the sample population differs from eligible nonparticipants, including in randomized controlled trials. External validity is defined as the extent to which the study population and setting are representative of the larger source population the study intends to represent. External validity may be limited given the characteristics of the women enrolled in the ARRIVE trial and the practice settings where the study was conducted. This brief report provides concrete suggestions for further analyses that could help solidify conclusions from the trial, and for further research questions that will continue advancement toward answering this complex question of how best to manage labor and birth decisions at full term among low-risk women.

A Labor Support Workshop to Improve Undergraduate Nursing Students' Understanding of the Importance of High Touch in a High-Tech World

This article presents the development and evaluation of a labor support workshop aimed at providing senior undergraduate nursing students with education on the provision of labor support. In collaboration with a Lamaze educator, a two and half hour interactive educational session was developed. The workshop included both a didactic and a hands-on component which included physical labor support strategies, which could be utilized in the clinical setting. Pre-and postintervention data was collected on students' knowledge and self-efficacy in the provision of labor support, as well as, data on their use of these strategies while in the clinical setting. The labor support workshop was well received by students (4.9/5) and increased their self-reported knowledge (p = <.001) and self-efficacy (p = <.001) in the provision of labor support.

Developing the Learning about Midwives and Birth Settings Video for Teaching About Birth Care Options

BACKGROUND

U.S. women's reports have indicated misconceptions about midwifery care and related birth options, yet these care approaches are associated with healthy birth outcomes. From the perspective of person-centered care, we aimed to address existing knowledge gaps on midwifery care by creating an accessible learning tool help inform future parents and community educators of evidence-based birth care options.

METHOD

Applied action research (AR) principles to develop a learning tool for public use. We conducted focus groups with nulliparous young adults who were university students, those who were nonstudent community members, and medical professionals to build content. We collected pre–post viewing data on knowledge, attitudes, and future behavioral intentions with university and community samples.

RESULTS

Our resultant 17-minute video contains content in three areas: (a) narratives from midwives, (b) narratives from parents, (c) information on midwives' credentialing and scope of care, birth settings, and safety studies. Evaluation data indicated that the video positively influenced viewers' related knowledge, attitudes, and future behavioral intentions.

DISCUSSION

Our iterative developmental process yielded a learning tool responsive to viewer input on communicating about nonnormative, safe birth care options. Initial data indicated promise of positively influencing viewers' attitudes and behavioral intentions toward midwife-attended birth in- and out-of-hospital. Future plans include publicly releasing the video and assessing long-term learning impact with initial study samples.

Women's Prenatal and Labor Experiences in a Hospital With an Early-Labor Lounge

OBJECTIVE

To evaluate the information that women with low-risk pregnancies received during the prenatal period about latent labor and the early-labor lounge (ELL) and their subsequent use of the ELL.

DESIGN

Cross-sectional design with survey.

SETTING/LOCAL PROBLEM

Community hospital in the northeastern United States with a low-risk cesarean birth rate of 33%, which exceeds the national target rate of 23.9%.

PARTICIPANTS

Low-risk, nulliparous, pregnant women with a term singleton vertex fetus at hospital admission (N = 67).

INTERVENTION/MEASUREMENTS

An electronic survey was administered before hospital discharge following birth. The survey assessed prenatal education, use of the ELL, admission characteristics, and birth satisfaction. Descriptive analysis was used.

RESULTS

Nearly half (43.9%) of the women surveyed used the ELL. ELL users received prenatal care (72.3%), knew signs of active labor (93.1%), and had a cesarean birth rate of 7.1%. Significantly greater proportions of women prenatally cared for by midwives reported knowledge of the signs of early labor (100% vs. 80%; χ² = 4.4, p = .04) and of the availability of the ELL (18.2% vs. 70.6%; χ² = 15.2, p < .001). A range of activities were offered in the ELL, and at least 75% of women indicated that all activities were helpful during latent labor. Birth satisfaction scores, measured on a scale of 0 to 40, with 40 indicating greatest satisfaction, ranged from 22 to 35 among ELL participants.

CONCLUSION

An ELL is a care innovation that hospitals can consider for providing support to women with low-risk pregnancies during the latent phase of labor. Women who used the ELL reported feeling that it provided guidance and support. An ELL is a woman-centered option for delayed admission.

Associations Among Intrapartum Interventions and Cesarean Birth in Low-Risk Nulliparous Women with Spontaneous Onset of Labor

INTRODUCTION

Cesarean birth rates vary widely across hospitals in the United States, even among women who are considered low-risk for the procedure. This variation has been attributed to differences in health care provider practice, but few studies have explored patterns of labor management in relation to cesarean birth.

METHODS

This was a retrospective observational study of 26,259 nulliparous, term, singleton gestation, vertex presentation births following spontaneous onset of labor. Births occurred from 2002 to 2007 in 11 hospitals in the Consortium on Safe Labor. Generalized linear mixed modeling was used to examine the relationship between intrapartum interventions (amniotomy, epidural analgesia, oxytocin augmentation) used individually and in combination and the outcome of cesarean birth.

RESULTS

More than 90% of the women in this low-risk sample received at least one intervention regardless of mode of birth. Epidural analgesia was the most frequently applied intervention, both when used as a single intervention (18.7%) and in combination with other interventions (79.9%). The strongest associations between these interventions and cesarean birth were observed when 2 or 3 interventions were applied during labor. Compared with women who received no interventions, the strongest association was observed among women who received amniotomy-oxytocin augmentation (adjusted odds ratio [aOR], 1.89; 95% CI, 1.36-2.62). The use of all 3 interventions (amniotomy-epidural analgesia-oxytocin augmentation) showed a similar positive association with cesarean birth (aOR 1.83; 95% CI, 1.50-2.21).

DISCUSSION

Findings show that the combined use of amniotomy, epidural analgesia, and oxytocin augmentation is positively associated with cesarean birth. Additional research is needed to examine the timing and sequence of interventions as well as whether a causal relationship exists between combinations of interventions and cesarean birth in low-risk nulliparous women.

Shared Decision-Making With Choosing Wisely

Choosing Wisely is a national health care improvement campaign promoting conversations between women and their health care professionals about selecting high-value health care practices. It disseminates lists of recommendations and downloadable educational materials from professional societies on its website. In November 2018, we searched for and categorized Choosing Wisely recommendations pertinent to women's health care. Of 78 recommendations, 28 (36%) were related to perinatal care, 22 (28%) were related to gynecologic care, and 28 (36%) were related to women's health and general care. Twelve recommendations (17.6%) were related to antenatal care, 10 (14.7%) to intrapartum and postpartum care, and 10 (14.7%) to cervical cancer screening. These free resources can help frame the shared decision-making process in clinical practice.

Adaptation of the Childbirth Experience Questionnaire (CEQ) in China: A multisite cross-sectional study

BACKGROUND

The childbirth experience of women represents a significant aspect of quality care. Due to the lack of a reliable Chinese language tool for assessing childbirth experiences, examples must be adapted from other countries. The aim of this study was to translate an English version of the Childbirth Experience Questionnaire (CEQ) into Chinese and adapt this tool to the Chinese context.

METHODS

A questionnaire validation study was conducted. A forward-backward translation procedure involving the developer of the CEQ was conducted. The data were collected in postnatal wards at 50 birth facilities in 4 regions of Zhejiang Province, China. Women who gave birth vaginally at the investigated facilities during the study period completed an online questionnaire that included the Chinese version of the CEQ (CEQ-C), demographic information and clinical information. Psychometric analyses were performed to assess the internal and content consistency. After subdividing the sample into subsamples, an exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were applied to examine the structural validity. Known-group comparisons were performed to assess the discriminant validity.

RESULTS

Overall, 1747 women participated in this study. The content validity index (CVI) of the CEQ was 0.92. Based on the comments of the experts combined with the statistical results, we removed 3 items related to pain, sense of control and sense of security and changed 3 items to different dimensions. The CFA supported the four dimensions of the CEQ-C (standard root mean square residual (SRMR) = 0.037, root mean square error of approximation (RMSEA) = 0.036, comparative fit index (CFI) = 0.966, and Tucker-Lewis index (TLI) = 0.959). Cronbach's alpha of the CEQ-C was 0.88, and McDonald's omega value was 0.91. The duration of labor, delivery mode, parity, oxytocin augmentation, pain management, companionship, prenatal education and pain experienced exerted significant effects on the women's childbirth experiences.

CONCLUSIONS

Although some items performed differently in our analysis comparing the English and Chinese versions of the CEQ, the CEQ-C is reliable and valid. Additionally, the CEQ-C is an easy-to-use and promising tool for measuring childbirth experiences among Chinese women in facility settings that can be used to improve the quality of intrapartum care. Efforts are needed to provide women with respectful, evidence-based intrapartum care to facilitate positive childbirth experiences.

Cesarean overuse and the culture of care

OBJECTIVE

To assess hospital unit culture and clinician attitudes associated with varying rates of primary cesarean delivery.

DATA SOURCES/STUDY SETTING

Intrapartum nurses, midwives, and physicians recruited from 79 hospitals in California participating in efforts to reduce cesarean overuse.

STUDY DESIGN

Labor unit culture and clinician attitudes measured using a survey were linked to the California Maternal Data Center for birth outcomes and hospital covariates.

METHODS

Association with primary cesarean delivery rates was assessed using multivariate Poisson regression adjusted for hospital covariates.

PRINCIPAL FINDINGS

1718 respondents from 70 hospitals responded to the Labor Culture Survey. The "Unit Microculture" subscale was strongly associated with primary cesarean rate; the higher a unit scored on 8-items describing a culture supportive of vaginal birth (eg, nurses are encouraged to spend time in rooms with patients, and doulas are welcomed), the cesarean rate decreased by 41 percent (95% CI = -47 to -35 percent, P < 0.001). Discordant attitudes between nurses and physicians were associated with increased cesarean rates.

CONCLUSIONS

Hospital unit culture, clinician attitudes, and consistency between professions are strongly associated with primary cesarean rates. Improvement efforts to reduce cesarean overuse must address culture of care as a key part of the change process.

Healthy Birth Practice #2: Walk, Move Around, and Change Positions Throughout Labor

Women who use upright positions and are mobile during labor have shorter labors, less intervention, fewer cesarean births, and report less severe pain, and describe more satisfaction with their childbirth experience than women in recumbent positions. The evidence for supporting physiologic childbearing for optimal birth fails to disrupt intervention intensive hospital practices that deny 60% of women mobility in labor despite calls by maternity care organizations to not restrict mobility for low risk women in spontaneous labor.

Healthy Birth Practice #5: Avoid Giving Birth on Your Back and Follow Your Body's Urge to Push

Tradition, not evidence, continues to drive the management of the second stage of labor in most hospitals. This is an overview of current evidence associated with best practices for healthy outcomes for mothers and babies.

A priori choice of neuraxial labour analgesia and breastfeeding initiation success: a community-based cohort study in an Italian baby-friendly hospital

OBJECTIVE

To investigate whether the nature of the decision about receiving neuraxial labour analgesia is associated with breastfeeding initiation success (BIS), defined as exclusive breastfeeding until discharge associated with postnatal weight loss <7% at 60 hours from birth.

DESIGN

Single-centre community-based cohort study.

SETTING

An Italian baby-friendly hospital, from 1 July 2011 to 22 September 2015.

PARTICIPANTS

Inclusion criteria: women vaginally delivering singleton cephalic newborns and willing to breastfeed.

EXCLUSION CRITERIA

women who delivered in uterus-dead fetuses, were single or requested but did not receive neuraxial analgesia. Overall, 775 out of the 3628 enrolled women received neuraxial analgesia.

RESULTS

Compared with women who tried to cope with labour pain, those who decided a priori to receive neuraxial analgesia had less BIS (planned vaginal birth: 2121/3421 (62.0%), vs 102/207 (49.3%; p<0.001; risk difference (RD), 12.7%); actual vaginal birth: 1924/2994 (64.3%), vs 93/189 (49.2%; p<0.001; RD, 15.1%)). Multivariable analyses with antelabour-only confounders confirmed both associations (planned vaginal birth: relative risk (RR), 0.65; 95% CI, 0.48 to 0.87; actual vaginal birth: RR, 0.59; 95% CI, 0.43 to 0.80). Although women who requested analgesia as a last resort had less BIS than did those successfully coping with labour pain in the bivariable analyses (planned vaginal birth: 1804/2853 (63.2%), vs 317/568 (55.8%; p=0.001; RD, 7.4%); actual vaginal birth: 1665/2546 (65.4%), vs 259/448 (57.8%; p=0.002; RD, 7.6%)), multivariable analyses with either antelabour-only or peripartum confounders did not confirm these associations (planned vaginal birth: RR, 0.99; 95% CI, 0.80 to 1.23; actual vaginal birth: RR, 0.90; 95% CI, 0.69 to 1.16).

CONCLUSIONS

Compared with trying to cope with labour pain, a priori choice of neuraxial analgesia is negatively associated with BIS. Conversely, compared with having successfully coped with pain, requesting neuraxial analgesia as a last resort is not negatively associated with BIS.

Pregnancy-specific coping and changes in emotional distress from mid- to late pregnancy

Objective: To examine whether pregnancy-specific coping predicts changes in emotional distress from mid- to late pregnancy. Background: There is a need to identify ways of coping that reduce or elevate emotional distress in pregnant women as such distress increases the risk of adverse birth outcomes. Methods: 132 women receiving prenatal care from a university hospital midwifery practice were recruited prior to 25 weeks gestation (M = 19.58, SD = 5.14). The state anxiety version of the State-Trait Personality Inventory (STPI) and the Revised Prenatal Distress Questionnaire (NuPDQ) were administered in mid- (M = 25.7 weeks, SD = 4.55) and late (M = 33.4 weeks, SD = 4.18) pregnancy and the Revised Prenatal Coping Inventory (NuPCI) at the latter timepoint. Results: Factor analysis of the NuPCI identified five distinct, conceptually interpretable types of coping: Prayer/Spirituality, Receiving Social Support, Planning/Preparation, Positive Appraisal, and Avoidant Coping. Avoidant Coping was used least frequently and Positive Appraisal was used most. The STPI and NuPDQ were aggregated to create a measure of emotional distress. After controlling for mid-pregnancy distress, Avoidant Coping predicted greater emotional distress in late pregnancy (β = .18, R² = .61, p < .01) and Positive Appraisal predicted lower late pregnancy distress (β = -.15, R² = .60, p < .01). Conclusion: This is one of the first studies to demonstrate that specific ways of coping with stress during pregnancy predict changes in pregnant women's emotional distress. The NuPCI is a psychometrically sound self-report instrument to examine coping and its association with emotional distress.

Fetal Heart Rate Auscultation, 3rd edition

The use of intermittent auscultation (IA) for fetal surveillance during labor decreased with the introduction of electronic fetal monitoring (EFM). The increased use of EFM is associated with an increase in cesarean births. IA is an evidence-based method of fetal surveillance during labor for women with low risk pregnancies and considered one component of comprehensive efforts to reduce the primary cesarean rate and promote vaginal birth. Many clinicians are not familiar with IA practice. This practice monograph includes information on IA techniques; interpretation and documentation; clinical decision-making and interventions; communication; education, staffing, legal issues, and strategies to promote implementation of IA into practice.

False Alarms and Overmonitoring: Major Factors in Alarm Fatigue Among Labor Nurses

BACKGROUND

Nurses can be exposed to hundreds of alarms during their shift, contributing to alarm fatigue.

PURPOSE

The purposes were to explore similarities and differences in perceptions of clinical alarms by labor nurses caring for generally healthy women compared with perceptions of adult intensive care unit (ICU) and neonatal ICU nurses caring for critically ill patients and to seek nurses' suggestions for potential improvements.

METHODS

Nurses were asked via focus groups about the utility of clinical alarms from medical devices.

RESULTS

There was consensus that false alarms and too many devices generating alarms contributed to alarm fatigue, and most alarms lacked clinical relevance. Nurses identified certain types of alarms that they responded to immediately, but the vast majority of the alarms did not contribute to their clinical assessment or planned nursing care.

CONCLUSIONS

Monitoring only those patients who need it and only those physiologic values that are warranted, based on patient condition, may decrease alarm burden.

Facility Design: Reimagining Approaches to Childbirth in Hospital and Birth Center Settings

Few maternity care clinicians are aware of the current regulations that guide design standards for childbirth facilities in the United States or the regulatory history. There is considerable variance among state regulations as well as oversight of facility standards for healthcare settings. Understanding evidence-based recommendations on how facility design affects health outcomes is critical to reversing the rise in maternal mortality and morbidity. A variety of measures can be implemented that promise to improve user satisfaction, quality of care, and efficiency for all who engage in the childbirth environment. Recommendations for change include broader assessment to better understand how clinicians and consumers simultaneously maneuver within a complex system. Key metrics include evaluation of workflow within available space, patient acuity and census patterns, integration of evidence-based recommendations, and options that promote physiologic birth. For the changes to succeed, human centered design must be implemented and diverse clinicians and consumers engaged in all phases of planning and implementation. Exploring characteristics and outcomes of low-risk women who receive care in a freestanding birth center or the European alongside maternity unit provides opportunity to reimagine and address improvements for inpatient, hospital birth.

Applying a physiologic partograph to Consortium on Safe Labor data to identify opportunities for safely decreasing cesarean births among nulliparous women

BACKGROUND

The timing of hospital admission for women with spontaneous labor onset and the criteria used to assess active labor progress and diagnose labor dystocia may significantly influence women's risk for primary cesarean birth. Our aims were to assess associations of labor status at admission (i.e., preactive or active) and active labor progress (i.e., dystocic or physiologic) with oxytocin augmentation, cesarean birth, and adverse neonatal outcome rates.

METHODS

A sample of low-risk, nulliparous women admitted to hospitals for spontaneous labor onset was extracted from the Consortium on Safe Labor (n = 27 077). Binomial logistic regression was used to assess associations between labor classifications and outcomes.

RESULTS

At admission, 68.0% of women were in preactive labor and 32.0% were in active labor. Cesarean rates for these groups were 18.0% and 7.2%, respectively (adjusted odds ratio [AOR] 2.69; 95% CI 2.45-2.96). Oxytocin augmentation and adverse neonatal outcomes were more likely for women admitted in preactive labor. Among women admitted in active labor, 9.3% experienced labor dystocia and 90.7% progressed physiologically. Cesarean rates for these groups were 20.4% and 5.9%, respectively (AOR 3.02; 95% CI 2.45-3.73). Nearly half of the cesareans performed for dystocia among women admitted in active labor occurred when cervical dilation was physiologic. Oxytocin augmentation and adverse neonatal outcomes were more likely when active labor was dystocic.

CONCLUSIONS

Adoption of evidence-based, standardized approaches for diagnosing active labor onset, assessing labor progress, and diagnosing dystocia may safely decrease oxytocin augmentation and cesarean birth rates in the United States.

Pharmacokinetics of Increased Nelfinavir Plasma Concentrations in Women During Pregnancy and Postpartum

This study aims to evaluate the safety, acceptability, and pharmacokinetics (PK) of an increased dose of nelfinavir (NFV) during the third trimester of pregnancy. The study was registered as part of the International Maternal Pediatric Adolescent AIDS Clinical Trials network (IMPAACT-P1026s), an ongoing multicenter prospective cohort study of antiretroviral PK during pregnancy (NCT00042289). NFV intensive PK evaluations were performed at steady state during the third trimester of pregnancy and 2-3 weeks postpartum. Plasma concentrations of NFV and its active metabolite, hydroxyl-tert-butylamide (M8) were measured using high-performance liquid chromatography with ultraviolet detection. A total of 18 women are included in the analysis. NFV area under the concentration-time curve (AUC) with the increased dose during the third trimester was nearly identical to the standard dose postpartum, with a geometric mean ratio for third trimester to postpartum AUC of 0.98 (90%CI 0.71-1.35). Despite the increased dose, M8 AUC was lower during the third trimester compared to postpartum (0.53, IQR [0.38-0.75]), as was the M8/NFV AUC ratio (0.51, IQR [0.42-0.63]). NFV AUC_0-12 was above target in 15 of 18 (83%) of participants during the third trimester compared to 14 of 16 (88%) postpartum. No major safety concerns were noted. Increasing the NFV dose to 1875 mg twice daily during the third trimester achieved similar concentrations postpartum compared to standard dosing (1250 mg twice daily). Increased NFV dose regimens may still have some benefit to human immunodeficiency virus (HIV)-positive pregnant women living in countries where novel protease inhibitors are currently unavailable or in individuals who are intolerant to ritonavir-boosted HIV medications.

A Planning Checklist for Interprofessional Consultations for Women in Midwifery Care

Team-based, interprofessional models of maternity care can allow women to receive personalized care based on their health needs and personal preferences. However, involvement of multiple health care providers can fragment care and increase communication errors, which are a major cause of preventable maternal morbidity and mortality. In order to improve communication within one health system, a community-engaged approach was used to develop a planning checklist for the care of women who began care with midwives but developed risks for poor perinatal outcomes. The planning checklist was constructed using feedback from women, nurses, midwives, and physicians in one interprofessional, collaborative network. In feasibility testing during 50 collaborative visits, the planning checklist provided a prompt to generate a comprehensive plan for maternity care and elucidate the rationale for interventions to women and future health care providers. In interviews after implementation of the checklist within a new collaborative format of prenatal physician consultations, women were pleased with the information received, and nurses, midwives, and physicians were positive about improved communication. This tool, developed with stakeholder input, was easy to implement and qualitatively beneficial to satisfaction and health system function. This article details the creation, implementation, and qualitative evaluation of the planning checklist. The checklist is provided and can be modified to meet the needs of other health systems.

Likelihood of cesarean birth among parous women after applying leading active labor diagnostic guidelines

OBJECTIVES

Hospital admission during early labor may increase women's risk for medical and surgical interventions. However, it is unclear which diagnostic guideline is best suited for identifying the active phase of labor among parous women. Dr. Emanuel Friedman, the United Kingdom's National Institute for Health and Care Excellence (NICE), and the American College of Obstetricians and Gynecologists/Society for Maternal-Fetal Medicine (ACOG/SMFM) support different active labor diagnostic guidelines. Our aims were (1) to determine the proportions of parous women admitted to the hospital before or in active labor per these leading guidelines and (2) to compare associations of labor status at admission (i.e., early labor or active labor) with oxytocin augmentation, cesarean birth, and adverse birth outcomes when using the different active labor diagnostic guidelines.

DESIGN

Active labor diagnostic guidelines were applied retrospectively to cervical examination data. Binomial logistic regression was used to assess associations of labor status at admission (i.e., early labor relative to active labor) and outcomes.

SETTING

A large, academic, tertiary medical center in the Midwestern United States.

PARTICIPANTS

Parous women with spontaneous labor onset who gave birth to a single, cephalic-presenting fetus at term gestation between 2006 and 2010 (n = 3,219).

FINDINGS

At admission, 28.8%, 71.9%, and 24.4% of parous women were in active labor per Friedman, NICE, and ACOG/SMFM diagnostic guidelines, respectively. Oxytocin augmentation was more likely among women admitted in early labor, regardless of the diagnostic strategy used (p < 0.001 for each guideline). Cesarean birth was also more likely among women admitted before versus in active labor according to all guidelines (Friedman: adjusted odds ratio [AOR] 3.63 [95% CI 1.46-9.03]), NICE: AOR 2.71 [95% CI 1.47-4.99]), and ACOG/SMFM: AOR 2.11 [95% CI 1.02-4.34]). There were no differences in a composite measure of adverse outcomes within active labor diagnostic guidelines after adjusting for covariates.

KEY CONCLUSIONS

Many parous women with spontaneous labor onset are admitted to the hospital before active labor. These women are more likely to receive oxytocin augmentation during labor and are more likely to have a cesarean birth.

IMPLICATIONS FOR PRACTICE

Diagnosing active labor prior to admission or prior to intervention aimed at speeding labor after admission may decrease likelihoods for primary cesarean births. The NICE dilation-rate based active labor diagnostic guideline is more inclusive than Friedman or ACOG/SMFM guidelines and its use may be the most clinically-useful for improving the likelihood of vaginal birth among parous women.

Barriers and facilitators to birth without epidural in a tertiary obstetric referral center: Perspectives of health care professionals and patients

BACKGROUND

Epidural rates are high in tertiary obstetric referral centers, even though many patients in tertiary settings might not want or need epidural analgesia. Epidural rates are influenced by factors including labor support and routine medical intervention. This study aimed to identify barriers and facilitators to birth without epidural in a Canadian tertiary center, from the perspectives of doctors, nurses, and patients.

METHODS

In this qualitative exploratory study, individual, semi-structured interviews were conducted in 2016 with 5 doctors, 5 nurses, and 4 patients who intended to birth without epidural. Interviews were audio-recorded, transcribed, and analyzed using inductive qualitative thematic analysis.

RESULTS

Several contextual factors in the tertiary center facilitated or were barriers to birth without epidural. The following themes emerged: (1) differing perceptions of pain, (2) being ready for things to go wrong, (3) labor support is more labor intensive, and (4) having insufficient resources for birth without epidural.

CONCLUSIONS

Reconciling patient birth goals with staff focus on patient safety is challenging in the tertiary context. Discrepancies between health care professional and patient attitudes about childbirth pain may influence decision-making about epidural use. Maintaining labor support skills is challenging for health care professionals who have limited exposure to birth without epidural. There is a need to allocate dedicated resources to better support birth without epidural. Specifically, support could be improved through the implementation of guidelines for assessment and management of labor pain, provision of a variety of pain management options, and labor support training for health care professionals.
