Abstract
OBJECTIVE To evaluate whether induction of labor (IOL) is associated with cesarean birth (CB) and perinatal mortality in uncomplicated first births at term compared with expectant management outside the confines of a randomized controlled trial. METHODS Population-based retrospective cohort study of all births in Victoria, Australia, from 2010 to 2018 (n = 640,191). Preliminary analysis compared IOL at 37 weeks with expectant management at that gestational age and beyond for uncomplicated pregnancies. Similar comparisons were made for IOL at 38, 39, 40, and 41 weeks of gestation and expectant management. The primary analysis repeated these comparisons, limiting the population to nulliparous women with uncomplicated pregnancies and excluding those with a medical indication for IOL. We compared perinatal mortality between groups using Chi-square tests and multivariable logistic regression for all other comparisons. Adjusted odds ratios and 99% confidence intervals were reported. p < 0.01 denoted statistical significance. RESULTS Among nulliparous, uncomplicated pregnancies at ≥37 weeks of gestation in Victoria, IOL increased from 24.6% in 2010 to 30.0% in 2018 (p < 0.001). In contrast to the preliminary analysis, the primary analysis showed that IOL in lower-risk nulliparous women was associated with increased odds of CB when performed at 38 (aOR 1.23(1.13-1.32)), 39 (aOR 1.31(1.23-1.40)), 40 (aOR 1.42(1.35-1.50)), and 41 weeks of gestation (aOR 1.43(1.35-1.51)). Perinatal mortality was rare in both groups and non-significantly lower in the induced group at most gestations. DISCUSSION For lower-risk nulliparous women, the odds of CB increased with IOL from 38 weeks of gestation, along with decreased odds of perinatal mortality at 41 weeks only.

Abstract
Fetal death is defined as the spontaneous cessation of cardiac activity after fourteen weeks of amenorrhea. In France, the prevalence of fetal death after 22 weeks is between 3.2 and 4.4/1000 births. Regarding the prevention of fetal death in the general population, it is not recommended to counsel for rest and not to prescribe vitamin A, vitamin D nor micronutrient supplementation for the sole purpose of reducing the risk of fetal death (Weak recommendations; Low quality of evidence). It is not recommended to prescribe aspirin (Weak recommendation; Very low quality of evidence). It is recommended to offer vaccination against influenza in epidemic periods and against SARS-CoV-2 (Strong recommendations; Low quality of evidence). It is not recommended to systematically look for nuchal cord encirclements during prenatal screening ultrasounds (Strong Recommendation; Low Quality of Evidence) and not to perform systematic antepartum monitoring by cardiotocography (Weak Recommendation; Very Low Quality of Evidence). It is not recommended to ask women to perform an active fetal movement count to reduce the risk of fetal death (Strong Recommendation; High Quality of Evidence). Regarding evaluation in the event of fetal death, it is suggested that an external fetal examination be systematically offered (Expert opinion). It is recommended that a fetopathological and anatomopathological examination of the placenta be carried out to participate in cause identification (Strong Recommendation. Moderate quality of evidence). It is recommended that chromosomal analysis by microarray testing be performed rather than conventional karyotype, in order to be able to identify a potentially causal anomaly more frequently (Strong Recommendation, moderate quality of evidence); to this end, it is suggested that postnatal sampling of the placental fetal surface for genetic purposes be preferred (Expert Opinion). It is suggested to test for antiphospholipid antibodies and systematically perform a Kleihauer test and a test for irregular agglutinins (Expert opinion). It is suggested to offer a summary consultation, with the aim of assessing the physical and psychological status of the parents, reporting the results, discussing the cause and providing information on monitoring for a subsequent pregnancy (Expert opinion). Regarding announcement and support, it is suggested to announce fetal death without ambiguity, using simple words and adapting to each situation, and then to support couples with empathy in the various stages of their care (Expert opinion). Regarding management, it is suggested that, in the absence of a situation at risk of disseminated intravascular coagulation or maternal vitality, the patient's wishes should be taken into account when determining the time between the diagnosis of fetal death and induction of birth. Returning home is possible if it's the patient wish (Expert opinion). In all situations excluding maternal life-threatening emergencies, the preferred mode of delivery is vaginal delivery, regardless the history of cesarean section(s) history (Expert opinion). In the event of fetal death, it is recommended that mifepristone 200mg be prescribed at least 24hours before induction, to reduce the delay between induction and delivery (Low recommendation. Low quality of evidence). There are insufficient data in the literature to make a recommendation regarding the route of administration (vaginal or oral) of misoprostol, neither the type of prostaglandin to reduce induction-delivery time or maternal morbidity. It is suggested that perimedullary analgesia be introduced at the start of induction if the patient asks, regardless of gestational age. It is suggested to prescribe cabergoline immediately in the postpartum period in order to avoid lactation, whatever the gestational age, after discussing the side effects of the treatment with the patient (Expert opinion). The risk of recurrence of fetal death after unexplained fetal death does not appear to be increased in subsequent pregnancies, and data from the literature are insufficient to make a recommendation on the prescription of aspirin. In the event of a history of fetal death due to vascular issues, low-dose aspirin is recommended to reduce perinatal morbidity, and should not be combined with heparin therapy (Low recommendation, very low quality of evidence). It is suggested not to recommend an optimal delay before initiating another pregnancy just because of the history of fetal death. It is suggested that the woman and co-parent be informed of the possibility of psychological support. Fetal heart rate monitoring is not indicated solely because of a history of fetal death. It is suggested that delivery not be systematically induced. However, induction can be considered depending on the context and parental request. The gestational age will be discussed, taking into account the benefits and risks, especially before 39 weeks. If a cause of fetal death is identified, management will be adapted on a case-by-case basis (expert opinion). In the event of fetal death occurring in a twin pregnancy, it is suggested that the surviving twin be evaluated as soon as the diagnosis of fetal death is made. In the case of dichorionic pregnancy, it is suggested to offer ultrasound monitoring on a monthly basis. It is suggested not to deliver prematurely following fetal death of a twin. If fetal death occurs in a monochorionic twin pregnancy, it is suggested to contact the referral competence center, in order to urgently look for signs of acute fetal anemia on ultrasound in the surviving twin, and to carry out weekly ultrasound monitoring for the first month. It is suggested not to induce birth immediately.

Abstract
OBJECTIVE We aim to examine the population-level rates of induction, stillbirth, perinatal mortality, and neonatal death before and after the ARRIVE (A Randomized Trial of Induction Versus Expectant Management) trial. STUDY DESIGN This study was a cross-sectional analysis of publicly available U.S. Live Birth data linked with Infant Death and Fetal Death certificate data from National Vital Statistics Online. We limited analyses to nulliparous individuals with singleton pregnancy and cephalic presentation who delivered at 39 weeks or greater. The pre- and post-ARRIVE periods spanned from August 2016 to July 2018, and from January 2019 to December 2020, respectively. Our primary outcome was a stillbirth. Secondary outcomes included induction of labor, perinatal mortality, and neonatal death. Outcomes were compared between the pre- and post-ARRIVE periods. Modified Poisson regression was used to calculate adjusted relative risks (aRRs). RESULTS Of 2,817,071 births, there were 1,454,346 births in the pre-ARRIVE period and 1,362,725 in the post-ARRIVE period; there were 1,196 and 1,062 stillbirths in the pre- and post-ARRIVE periods, respectively. Compared to the pre-ARRIVE period, the post-ARRIVE period was not associated with a significant decrease in the risk of stillbirth at 39 weeks or greater (aRR 0.92 [95% confidence interval {95% CI} 0.85-1.00]) and stillbirth at 40 weeks or greater (aRR 0.92 [95% CI 0.82-1.04]). Compared to the pre-ARRIVE trial period, the post-ARRIVE trial was associated with increased rates of induction of labor at 39 weeks (aRR 1.37 [95% CI 1.37-1.38]) and 40 weeks (aRR 1.24 [95% CI 1.24-1.25]. Similar to stillbirth, there was no significant decrease in the risk of perinatal mortality at 39 weeks or greater or 40 weeks or greater. There was also no statistically significant change in neonatal death rates at 39 weeks or greater or at 40 weeks or greater. CONCLUSION The increase in induction of labor at 39 weeks was not large enough to impact the stillbirth rate at 39 weeks or greater. KEY POINTS · Post-ARRIVE trial, rate of induction of labor increased at 39 and 40 weeks.. · Post-ARRIVE trial, stillbirth and perinatal mortality rates remained unchanged.. · Induction rate rise post-ARRIVE trial did not impact neonatal death rates..

Abstract
OBJECTIVE To assess the effect of propranolol on time to delivery among patients undergoing induction or augmentation of labor. DATA SOURCES PubMed, Scopus, Cochrane Library, ClinicalTrials.gov, and CINAHL (EBSCO) were searched from inception to December 2023. STUDY ELIGIBILITY CRITERIA Randomized controlled trials (RCTs) that examined the impact of propranolol on time to delivery among patients undergoing induction or augmentation of labor were included. RCTs that included stillbirth before randomization, non-randomized trials, observational, cohort, case control, or studies in which the control group included an intervention other than standard care were excluded. STUDY APPRAISAL AND SYNTHESIS METHODS Primary outcome was time to delivery after administration of propranolol among patients undergoing induction or augmentation of labor. The summary measures were reported as summary mean difference (MD) or relative risk with 95% of confidence interval (CI). RESULTS Nine RCTs including 1,182 patients were included in this meta-analysis. Five studies investigated the effect of propranolol among patients undergoing induction of labor (IOL) and demonstrated a significant decrease in time to delivery (MD, -91.5 minutes, 95% CI -110.6 to -72.4). Four studies investigated the effect of propranolol among patients undergoing augmentation of labor and showed no significant decrease in time to delivery (MD, -2.98 minutes, 95% CI -21.6 to 15.6). Our pooled analysis demonstrated that the use of propranolol in IOL and augmentation was associated with a decrease in time to delivery from administration of propranolol compared to placebo (mean difference, -46.15 minutes, 95% CI -59.48 to -32.81). The meta-analysis found no increased risk of PPH, blood transfusion, cesarean delivery rates, or NICU admission with the use of propranolol during labor. CONCLUSION The use of propranolol during induction of labor shortens overall time to delivery by about 91 minutes and did not significantly decrease time to delivery in those undergoing augmentation of labor.

Abstract
OBJECTIVE To evaluate the association of labor induction on cesarean delivery and other maternal and neonatal outcomes in low-risk, full-term patients in community hospitals during a period of concerted effort to safely prevent cesarean delivery. METHODS We performed a retrospective cohort study using the California Maternal Data Center comprised linked discharge diagnoses and birth certificate data for all low-risk, nulliparous, term, singleton, vertex (NTSV) individuals between 39 and 41 weeks from three Sacramento Valley community hospitals from 2016 to 2022 (N = 10,821) during a period of state-wide efforts to safely reduce cesarean rates. Logistic regression was used to calculate odds ratios (ORs) and adjusted odds ratios (aORs) after labor induction in two time periods before and after the ARRIVE trial. RESULTS During the study period, labor induction increased from 14.7% to 23.1%. Controlling for maternal age, pre-pregnancy BMI, birthweight, maternal race and ethnicity, birthplace, English language, gestational age, Medicaid status, delivery year, and labor induction was associated with an increased aOR of 1.67 (95% CI 1.48-1.89) for cesarean delivery. We found a trend toward increased aOR of chorioamnionitis but no differences in blood transfusion, severe maternal morbidity, unexpected newborn complications, chorioamnionitis, operative vaginal delivery, maternal lacerations, and shoulder dystocia with labor induction. A decrease aOR of cesarean delivery was observed comparing all births in 2019-2021 to 2016-2018. CONCLUSION Labor induction was associated with an increased aOR for cesarean delivery both before and after the ARRIVE trial. A decreased aOR for cesarean delivery was observed during the period of statewide efforts to safely reduce cesarean delivery both with and without labor induction.

Abstract
OBJECTIVE We aimed to examine rates of induction of labor at 39 weeks and cesarean delivery before and after the ARRIVE (A Randomized Trial of Induction Versus Expectant Management) trial stratified by body mass index (BMI; kg/m2) category. STUDY DESIGN This was a repeated cross-sectional analysis of publicly available U.S. birth certificate data from 2015 to 2021. We limited analyses to nulliparous individuals with a singleton pregnancy, cephalic presentation, without chronic hypertension, diabetes (gestational or pregestational), and fetal anomaly who delivered between 39 and 42 weeks' gestation. The pre-ARRIVE period spanned from August 2016 to July 2018 and the post-ARRIVE period spanned from January 2019 to December 2020. The dissemination period of the ARRIVE trial was from August 2018 to December 2018. Our co-primary outcomes were induction at 39 weeks and cesarean delivery. Our secondary outcomes were overall induction of labor and preeclampsia. We conducted an interrupted time series analysis after stratifying by prepregnancy BMI (<40 or ≥40). Negative binomial regression was used to calculate adjusted incident rate ratios with 95% confidence intervals. RESULTS Of 2,122,267 individuals that were included, 2,051,050 had BMI <40 and 71,217 had BMI ≥40. In individuals with BMI <40, the post-ARRIVE period compared to the pre-ARRIVE period was associated with an increased rate of induction of labor at 39 weeks, a decreased rate of cesarean delivery, and an increased rate of overall induction of labor. In individuals with BMI ≥40, the post-ARRIVE period compared to the pre-ARRIVE period was associated with an increased rate of induction of labor at 39 weeks, an increased rate of overall induction of labor and a decreased rate of preeclampsia; however, the decrease in the rate of cesarean delivery was not significant. CONCLUSION An increase in induction of labor at 39 weeks' gestation in individuals with BMI ≥40 was not associated with a decrease in the cesarean delivery rate. KEY POINTS · The ARRIVE trial increased 39-week labor inductions in BMI <40 and ≥40.. · BMI <40 had fewer cesareans; BMI ≥40 showed no significant decrease.. · Offering labor induction is reasonable as cesarean rates didn't increase..

Abstract
OBJECTIVE This study aimed to assess the impact of implementation of an induction of labor (IOL) guideline on IOL length and utilization of evidence-based practices. STUDY DESIGN We conducted a quality improvement project to increase utilization of three evidence-based IOL practices: combined agent ripening, vaginal misoprostol, and early amniotomy. Singletons with intact membranes and cervical dilation ≤2 cm admitted for IOL were included. Primary outcome was IOL length. Secondary outcomes included cesarean delivery and practice utilization. We compared preimplementation (PRE; November 1, 2021 through January 31, 2022) to postimplementation (POST; March 1, 2022 through April 30, 2022) with sensitivity analyses by self-reported race and ethnicity. Cox proportional hazards models and logistic regression were used to test the association between period and outcomes. RESULTS Among 495 birthing people (PRE, n = 293; POST, n = 202), IOL length was shorter POST (22.0 vs. 18.3 h, p = 0.003), with faster time to delivery (adjusted hazard ratio [aHR] 1.38, 95% CI 1.15-1.66), more birthing people delivered within 24 hours (57 vs. 68.8%, adjusted odds ratio [aOR] 1.90 [95% CI 1.25-2.89]), and no difference in cesarean. Utilization of combined agent ripening (31.1 vs. 42.6%, p = 0.009), vaginal misoprostol (34.5 vs. 68.3%, p < 0.001), and early amniotomy (19.1 vs. 31.7%, p = 0.001) increased POST. CONCLUSION Implementation of an evidence-based IOL guideline is associated with shorter induction time. Additional implementation efforts to increase adoption of practices are needed to optimize outcomes after IOL. KEY POINTS · Implementation of an IOL guideline is associated with faster time to delivery.. · Evidence-based induction practices were used more often after guideline implementation.. · Adoption of evidence-based induction practices is variable even with a guideline..

Am J Obstet Gynecol MFM 2024; 6:101373. [PMID: 38583714 DOI: 10.1016/j.ajogmf.2024.101373] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/29/2024] [Revised: 03/13/2024] [Accepted: 04/01/2024] [Indexed: 04/09/2024]
Abstract
BACKGROUND In low-risk pregnancies, a third-trimester ultrasound examination is indicated if fundal height measurement and gestational age discrepancy are observed. Despite potential improvement in the detection of ultrasound abnormality, prior trials to date on universal third-trimester ultrasound examination in low-risk pregnancies, compared with indicated ultrasound examination, have not demonstrated improvement in neonatal or maternal adverse outcomes. OBJECTIVE The primary objective was to determine if universal third-trimester ultrasound examination in low-risk pregnancies could attenuate composite neonatal adverse outcomes. The secondary objectives were to compare changes in composite maternal adverse outcomes and detection of abnormalities of fetal growth (fetal growth restriction or large for gestational age) or amniotic fluid (oligohydramnios or polyhydramnios). STUDY DESIGN Our pre-post intervention study at 9 locations included low-risk pregnancies, those without indication for ultrasound examination in the third trimester. Compared with indicated ultrasound in the preimplementation period, in the postimplementation period, all patients were scheduled for ultrasound examination at 36.0-37.6 weeks. In both periods, clinicians intervened on the basis of abnormalities identified. Composite neonatal adverse outcomes included any of: Apgar score ≤5 at 5 minutes, cord pH <7.00, birth trauma (bone fracture or brachial plexus palsy), intubation for >24 hours, hypoxic-ischemic encephalopathy, seizure, sepsis (bacteremia proven with blood culture), meconium aspiration syndrome, intraventricular hemorrhage grade III or IV, periventricular leukomalacia, necrotizing enterocolitis, stillbirth after 36 weeks, or neonatal death within 28 days of birth. Composite maternal adverse outcomes included any of the following: chorioamnionitis, wound infection, estimated blood loss >1000 mL, blood transfusion, deep venous thrombus or pulmonary embolism, admission to intensive care unit, or death. Using Bayesian statistics, we calculated a sample size of 600 individuals in each arm to detect >75% probability of any reduction in primary outcome (80% power; 50% hypothesized risk reduction). RESULTS During the preintervention phase, 747 individuals were identified during the initial ultrasound examination, and among them, 568 (76.0%) met the inclusion criteria at 36.0-37.6 weeks; during the postintervention period, the corresponding numbers were 770 and 661 (85.8%). The rate of identified abnormalities of fetal growth or amniotic fluid increased from between the pre-post intervention period (7.1% vs 22.2%; P<.0001; number needed to diagnose, 7; 95% confidence interval, 5-9). The primary outcome occurred in 15 of 568 (2.6%) individuals in the preintervention and 12 of 661 (1.8%) in the postintervention group (83% probability of risk reduction; posterior relative risk, 0.69 [95% credible interval, 0.34-1.42]). The composite maternal adverse outcomes occurred in 8.6% in the preintervention and 6.5% in the postintervention group (90% probability of risk; posterior relative risk, 0.74 [95% credible interval, 0.49-1.15]). The number needed to treat to reduce composite neonatal adverse outcomes was 121 (95% confidence interval, 40-200). In addition, the number to reduce composite maternal adverse outcomes was 46 (95% confidence interval, 19-74), whereas the number to prevent cesarean delivery was 18 (95% confidence interval, 9-31). CONCLUSION Among low-risk pregnancies, compared with routine care with indicated ultrasound examination, implementation of a universal third-trimester ultrasound examination at 36.0-37.6 weeks attenuated composite neonatal and maternal adverse outcomes.

Obstetric Racial Disparities in the Era of the ARRIVE (A Randomized Trial of Induction Versus Expectant Management) Trial and the Coronavirus Disease 2019 (COVID-19) Pandemic. Obstet Gynecol 2024; 143:690-699. [PMID: 38547489 PMCID: PMC11031288 DOI: 10.1097/aog.0000000000005564] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2023] [Accepted: 02/01/2024] [Indexed: 04/08/2024]
Abstract
OBJECTIVE To evaluate the influence of the ARRIVE (A Randomized Trial of Induction Versus Expectant Management) trial and the coronavirus disease 2019 (COVID-19) pandemic on racial and ethnic differences in labor induction, pregnancy-associated hypertension, and cesarean delivery among non-Hispanic Black and non-Hispanic White low-risk, first-time pregnancies. METHODS We conducted an interrupted time series analysis of U.S. birth certificate data from maternal non-Hispanic Black and non-Hispanic White race and ethnicity, first pregnancy, 39 or more weeks of gestation, with no documented contraindication to vaginal delivery or expectant management beyond 39 weeks. We compared the rate of labor induction (primary outcome), pregnancy-associated hypertension, and cesarean delivery during three time periods: pre-ARRIVE (January 1, 2015-July 31, 2018), post-ARRIVE (November 1, 2018-February 29, 2020), and post-COVID-19 (March 1, 2020-December 31, 2021). RESULTS In the post-ARRIVE period, the rate of labor induction increased in both non-Hispanic White and non-Hispanic Black patients, with no statistically significant difference in the magnitude of increase between the two groups (rate ratio for race [RR race ] 0.98, 95% CI, 0.95-1.02, P =.289). Post-COVID-19, the rate of labor induction increased in non-Hispanic White but not non-Hispanic Black patients. The magnitude of the rate change between non-Hispanic White and non-Hispanic Black patients was significant (RR race 0.95, 95% CI, 0.92-0.99, P =.009). Non-Hispanic Black pregnant people were more likely to have pregnancy-associated hypertension and more often delivered by cesarean at all time periods. CONCLUSION Changes in obstetric practice after both the ARRIVE trial and the COVID-19 pandemic were not associated with changes in Black-White racial differences in labor induction, cesarean delivery, and pregnancy-associated hypertension.

Abstract
OBJECTIVE To develop and externally validate a prediction model to calculate the likelihood of prolonged induction of labor (induction start to delivery time > 36 hours). STUDY DESIGN This was a retrospective cohort study of all nulliparous women with singleton pregnancies and vertex presentation at term who underwent induction of labor and had a vaginal delivery at a single academic center. Women with contraindications for vaginal delivery were excluded. Analyses were limited to women with unfavorable cervix (both simplified Bishop score [dilation, station, and effacement: range 0-9] <6 and cervical dilation <3 cm). Prolonged induction of labor was defined as the duration of induction (induction start time to delivery) longer than 36 hours. A backward stepwise logistic regression analysis was used to identify the factors associated with prolonged induction of labor by considering maternal characteristics and comorbidities as well as fetal conditions. The final model was validated using an external dataset of the Consortium on Safe Labor after applying the same inclusion and exclusion criteria. We developed a receiver observer characteristic curve with area under the curve (AUC) in validation cohorts. RESULTS Of 2,118 women, 364 (17%) had prolonged induction of labor. Factors associated with prolonged induction of labor included body mass index at admission, hypertension, fetal conditions, and epidural. Factors including younger maternal age, prelabor rupture of membranes, and a more favorable simplified Bishop score were associated with a decreased likelihood of prolonged induction of labor. In the external validation cohort, 4,418 women were analyzed, of whom 188 (4%) had prolonged induction of labor. The AUC of the final model was 0.76 (95% confidence interval: 0.73-0.80) for the external validation cohort. The online calculator was created and is available at: https://medstarapps.org/obstetricriskcalculator. CONCLUSION Our externally validated model was efficient in predicting prolonged induction of labor with an unfavorable cervix. KEY POINTS · The number of inductions of labor at 39 weeks' gestation and beyond has been increasing.. · Our model had a good prediction of prolonged induction of labor.. · An online calculator has been created and available..

Oyelese Y. Randomized controlled trials: not always the "gold standard" for evidence in obstetrics and gynecology. Am J Obstet Gynecol 2024; 230:417-425.

Abstract
Randomized controlled trials are considered the "gold standard" for therapeutic interventions, and it is not uncommon for sweeping changes in medical practice to follow positive results from such trials. However, randomized controlled trials are not without their limitations. Physicians frequently view randomized controlled trials as infallible, whereas they tend to dismiss evidence derived from sources other than randomized controlled trials as less credible or reliable. In several situations in obstetrics and gynecology, there are no randomized controlled trials to help guide the clinician. In these circumstances, it is important to evaluate the entire body of evidence including observational studies, rather than dismiss interventions altogether simply because no randomized controlled trials exist. Randomized controlled trials and observational studies should be viewed as complementary rather than at odds with each other. Some reversals in widely adopted clinical practice have recently been implemented following subsequent studies that contradicted the outcomes of major randomized controlled trials. The most notable of these was the withdrawal from the market of 17-hydroxyprogesterone caproate for preterm birth prevention. Such reversals could potentially have been averted if the inherent limitations of randomized controlled trials were carefully considered before implementing these universal practice changes. This Clinical Opinion underscores the limitations of an exclusive reliance on randomized controlled trials while disregarding other evidence in determining how best to care for patients. Solutions are proposed that advocate that clinicians adopt a more balanced perspective that considers the entirety of the available medical evidence and the individual patient characteristics, needs, and wishes.

Abstract
BACKGROUND Outpatient term preinduction cervical ripening with mechanical agents has been associated with reduced length of stay, decreased cesarean delivery rates, low maternal and neonatal complications, and increased incidence of vaginal delivery within 24 hours. OBJECTIVE This study aimed to demonstrate equivalent efficacy between synthetic hygroscopic dilators and the single-balloon catheter for outpatient cervical ripening. STUDY DESIGN This randomized control equivalence trial compared synthetic hygroscopic dilators with the 30-mL silicone single-balloon catheter in primiparous and multiparous patients undergoing labor induction. The primary outcome was time from admission to delivery, with a prespecified 3-hour margin of equivalence. The secondary objectives were patient outcomes and perspectives. RESULTS Between March 1, 2019, and May 31, 2021, 1605 patients met the screening criteria, and 174 patients completed the study. The mean admission-to-delivery time was equivalent at 18.01 hours for the dilator group vs 17.55 hours for the balloon group (P=.04). The cesarean delivery rate of primiparous patients was similar at 28.1% with dilators vs 29.7% with the balloon. The groups had similar median cervical dilation and pain scores on insertion and admission. Overall patient satisfaction was high, 92.8% with dilators vs 96.2% with the balloon. The balloon group had significantly higher rates of early admission and device expulsion. CONCLUSION Although the enrollment goal was not met, our study suggests that synthetic hygroscopic dilators and the single-balloon catheter for outpatient cervical ripening are both efficacious with similar time from admission to delivery, pain scores, and patient satisfaction with the procedure.

Abstract
BACKGROUND The prevalence and risk factors of posttraumatic stress disorder after cesarean delivery, outside high-risk contexts, remain unclear. OBJECTIVE This study aimed to assess posttraumatic stress disorder prevalence and risk factors at 2 months postpartum among a general population of women with cesarean delivery. STUDY DESIGN This was a prospective ancillary cohort study of the Tranexamic Acid for Preventing Postpartum Hemorrhage after Cesarean Delivery (TRAAP2) trial, conducted in 27 French hospitals from 2018 to 2020, enrolling women expected to undergo cesarean delivery before or during labor at ≥34 weeks of gestation. After randomization, characteristics of the cesarean delivery and postpartum blood loss were prospectively collected. Two months after childbirth, posttraumatic stress disorder profile (presence of posttraumatic stress disorder symptoms) and provisional diagnosis (positive screening for diagnosis consistent with a posttraumatic stress disorder) were assessed by 2 self-administered questionnaires (Impact of Event Scale - Revised and Traumatic Event Scale). The corrected posttraumatic stress disorder prevalence was estimated with inverse probability weighting to take nonresponse into account. Associations between potential risk factors and posttraumatic stress disorder were analyzed by multivariate logistic or linear regression modeling according to the type of dependent variable. RESULTS In total, 2785 of 4431 women returned the Impact of Event Scale - Revised questionnaire and 2792 the Traumatic Event Scale (response rates of 62.9% and 63.0%). The prevalence of posttraumatic stress disorder profile was 9.0% (95% confidence interval, 7.8%-10.3%) and of provisional diagnosis 1.7% (95% confidence interval, 1.2%-2.4%). Characteristics associated with a higher risk of posttraumatic stress disorder profile were prepregnancy vulnerability factors (young age, high body mass index, and African-born migrant) and cesarean delivery-related obstetrical factors (cesarean delivery after induced labor [adjusted odds ratio, 1.81; 95% confidence interval, 1.14-2.87], postpartum hemorrhage [adjusted odds ratio, 1.61; 95% confidence interval, 1.04-2.46] and high-intensity pain during the postpartum stay [adjusted odds ratio, 1.90; 95% confidence interval, 1.17-3.11]). Women who had immediate skin-to-skin contact with their newborn were at lower risk of posttraumatic stress disorder (adjusted odds ratio, 0.66; 95% confidence interval, 0.46-0.98), and women with bad memories of delivery on day 2 postpartum were at higher risk (adjusted odds ratio, 3.20; 95% confidence interval, 1.97-5.12). The Impact of Event Scale - Revised and the Traumatic Event Scale yielded consistent results. CONCLUSION Approximately 1 in 11 women with cesarean deliveries had posttraumatic stress disorder symptoms at 2 months postpartum. Some obstetrical interventions and components of cesarean delivery management may influence this risk.

Am J Obstet Gynecol 2024; 230:S1138-S1145.

Abstract
The term "obstetric violence" has been used in the legislative language of several countries to protect mothers from abuse during pregnancy. Subsequently, it has been expanded to include a spectrum of obstetric procedures, such as induction of labor, episiotomy, and cesarean delivery, and has surfaced in the peer-reviewed literature. The term "obstetric violence" can be seen as quite strong and emotionally charged, which may lead to misunderstandings or misconceptions. It might be interpreted as implying a deliberate act of violence by healthcare providers when mistreatment can sometimes result from systemic issues, lack of training, or misunderstandings rather than intentional violence. "Obstetric mistreatment" is a more comprehensive term that can encompass a broader range of behaviors and actions. "Violence" generally refers to the intentional use of physical force to cause harm, injury, or damage to another person (eg, physical assault, domestic violence, street fights, or acts of terrorism), whereas "mistreatment" is a more general term and refers to the abuse, harm, or control exerted over another person (such as nonconsensual medical procedures, verbal abuse, disrespect, discrimination and stigmatization, or neglect, to name a few examples). There may be cases where unprofessional personnel may commit mistreatment and violence against pregnant patients, but as obstetrics is dedicated to the health and well-being of pregnant and fetal patients, mistreatment of obstetric patients should never be an intended component of professional obstetric care. It is necessary to move beyond the term "obstetric violence" in discourse and acknowledge and address the structural dimensions of abusive reproductive practices. Similarly, we do not use the term "psychiatric violence" for appropriately used professional procedures in psychiatry, such as electroshock therapy, or use the term "neurosurgical violence" when drilling a burr hole. There is an ongoing need to raise awareness about the potential mistreatment of obstetric patients within the context of abuse against women in general. Using the term "mistreatment in healthcare" instead of the more limited term "obstetric violence" is more appropriate and applies to all specialties when there is unprofessional abuse and mistreatment, such as biased care, neglect, emotional abuse (verbal), or physical abuse, including performing procedures that are unnecessary, unindicated, or without informed patient consent. Healthcare providers must promote unbiased, respectful, and patient-centered professional care; provide an ethical framework for all healthcare personnel; and work toward systemic change to prevent any mistreatment or abuse in our specialty.

Am J Obstet Gynecol 2024; 230:S775-S782.

Abstract
The "A Randomized Trial of Induction Versus Expectant Management" trial (ARRIVE trial) published in 2018 suggested that induction of labor can be considered a "reasonable option" for low-risk nulliparous women at ≥39 weeks of gestation. The study results led some professional societies to endorse the option for elective induction of labor at 39 weeks of gestation in low-risk nulliparas, and this has begun to change obstetrical practice. The ARRIVE trial provided valuable information supporting the benefits of induction of labor; however, the trial is insufficient to serve as the primary justification for widespread elective induction of labor at 39 weeks of gestation in low-risk nulliparas because of concerns about external validity. Thus, the French ARRIVE trial was designed to test the hypothesis in a different setting that elective induction of labor at 39 weeks of gestation in low-risk nulliparas leads to a lower cesarean delivery rate than expectant management. This ongoing trial has been criticized as "pseudoscientific" and telling "women where, when, and how to give birth." We reject these allegations and extensively examine the ethical framework that should govern clinical and research interventions, including elective induction of labor at 39 weeks of gestation in low-risk nulliparas. This study aimed to discuss the ethical issues that emerge from randomized trials of elective induction of labor at 39 weeks of gestation in low-risk nulliparas and the ethics of the clinical practice itself. The analysis of existing evidence shows the importance of further research on induction of labor at 39 weeks of gestation in low-risk women. Certain aspects of research ethics in this area, particularly the consent of pregnant women in a context where autonomy remains fragile, call for vigilance. In addition, we emphasize that childbirth is not only a medical object but also a social phenomenon that cannot be regarded only from the perspective of a health risk to be managed by clinical research. Further research on this issue is needed to allow pregnant women to make informed decisions, and the results should be integrated with social issues. The perspective of women is required in constructing, evaluating, and implementing medical interventions in childbirth, such as induction of labor at 39 weeks of gestation.

This review assessed the efficacy and safety of pharmacologic agents (prostaglandins, oxytocin, mifepristone, hyaluronidase, and nitric oxide donors) and mechanical methods (single- and double-balloon catheters, laminaria, membrane stripping, and amniotomy) and those generally considered under the rubric of complementary medicine (castor oil, nipple stimulation, sexual intercourse, herbal medicine, and acupuncture). A substantial body of published reports, including 2 large network meta-analyses, support the safety and efficacy of misoprostol (PGE1) when used for cervical ripening and labor induction. Misoprostol administered vaginally at doses of 50 μg has the highest probability of achieving vaginal delivery within 24 hours. Regardless of dosing, route, and schedule of administration, when used for cervical ripening and labor induction, prostaglandin E2 seems to have similar efficacy in decreasing cesarean delivery rates. Globally, although oxytocin represents the most widely used pharmacologic agent for labor induction, its effectiveness is highly dependent on parity and cervical status. Oxytocin is more effective than expectant management in inducing labor, and the efficacy of oxytocin is enhanced when combined with amniotomy. However, prostaglandins administered vaginally or intracervically are more effective in inducing labor than oxytocin. A single 200-mg oral tablet of mifepristone seems to represent the lowest effective dose for cervical ripening. The bulk of the literature assessing relaxin suggests this agent has limited benefit when used for this indication. Although intracervical injection of hyaluronidase may cause cervical ripening, the need for intracervical administration has limited the use of this agent. Concerning the vaginal administration of nitric oxide donors, including isosorbide mononitrate, isosorbide, nitroglycerin, and sodium nitroprusside, the higher incidence of side effects with these agents has limited their use. A synthetic hygroscopic cervical dilator has been found to be effective for preinduction cervical ripening. Although a pharmacologic agent may be administered after the use of the synthetic hygroscopic dilator, in an attempt to reduce the interval to vaginal delivery, concomitant use of mechanical and pharmacologic methods is being explored. Combining the use of a single-balloon catheter with dinoprostone, misoprostol, or oxytocin enhances the efficacy of these pharmacologic agents in cervical ripening and labor induction. The efficacy of single- and double-balloon catheters in cervical ripening and labor induction seems similar. To date, the combination of misoprostol with an intracervical catheter seems to be the best approach when balancing delivery times with safety. Although complementary methods are occasionally used by patients, given the lack of data documenting their efficacy and safety, these methods are rarely used in hospital settings.

Abstract
OBJECTIVE The aim of this study was to compare twice-daily versus once-daily administration of intravaginal PGE2 for induction of labor at term. Efficacy, safety, and patient satisfaction were evaluated. STUDY DESIGN For this single-center, randomized, comparative, open-label, two-arm, and parallel study, pregnant women with term singleton live pregnancies ≥ 37 weeks of gestation, medical indications for induction of labor, and Bishop score ≤ 6 were randomized to either the control group (induction of labor with PGE2 gel with repeat dose after 24 h) or the experimental group (repeat dose after 12 h). The primary outcome was induction-to-delivery interval time. Secondary outcomes were maternal and neonatal outcomes and patient satisfaction. RESULTS In total, 246 women were randomized to the control (n = 121) or experimental groups (n = 125). The mean time for initiation of induction to delivery was 9.4 h shorter in the experimental group compared to controls (p = 0.007). For control vs experimental, there were no differences in tachysystole (19/121, 15.7 % vs 21/124, 16.9 %, respectively; p = 0.79), cesarean section rate (18/121, 14.9 % vs 28/124, 22.6 % respectively; p = 0.12), or other main obstetrical or neonatal outcomes. Patients in the experimental group reported higher satisfaction with their induction (48/96, 50 % with once-daily vs 60/86, 69.8 % with twice-daily; p = 0.010). CONCLUSION Among women admitted for induction of labor at term, closer interval of vaginal PGE2 administration was associated with a significantly shorter induction-to-delivery time without increasing maternal or neonatal morbidity. Furthermore, the reduction in induction time was associated with improved patient experience of delivery.

Abstract
BACKGROUND Oxytocin is effective in reducing labour duration but can be associated with fetal and maternal complications that could potentially be reduced by discontinuing the treatment during labour. We aimed to assess the impact of discontinuing oxytocin during active labour on neonatal morbidity. METHODS STOPOXY was a multicentre, randomised, open-label, controlled, superiority trial conducted in 21 maternity units in France. Participants who received oxytocin before 4 cm dilation were randomly assigned 1:1 to either discontinuous oxytocin (oxytocin infusion stopped beyond a cervical dilation equal to or greater than 6 cm) or continuous oxytocin (administration of oxytocin continued until delivery). Randomisation was stratified by centre and parity. The primary outcome, neonatal morbidity, was assessed at birth using a composite variable defined by an umbilical arterial pH at birth less than 7·10, a base excess greater than 10 mmol/L, umbilical arterial lactates greater than 7 mmol/L, a 5-min Apgar score less than 7, or admission to the neonatal intensive care unit. Efficacy and safety was assessed in participants who were randomly assigned (excluding those who withdrew consent or were deemed ineligible after randomisation) and had reached a cervical dilation of at least 6 cm. This trial is registered with ClinicalTrials.gov, NCT03991091. FINDINGS Of 2459 participants randomly assigned between Jan 13, 2020, and Jan 24, 2022, 2170 were eligible to receive the intervention and were included in the final modified intention-to-treat analysis. The primary outcome occurred for 102 (9·6%) of 1067 participants (95% CI 7·9 to 11·5) in the discontinuous oxytocin group and for 101 (9·2%) of 1103 participants (7·6 to 11·0) in the continuous oxytocin group; absolute difference 0·4% (95% CI -2·1 to 2·9); relative risk 1·0 (95% CI 0·8 to 1·4). There were no clinically significant differences in adverse events between the two groups of the safety population. INTERPRETATION Among participants receiving oxytocin in early labour, discontinuing oxytocin when the active phase is reached does not clinically or statistically significantly reduce neonatal morbidity compared with continuous oxytocin.

Predicting Spontaneous Labor beyond 39 Weeks among Low-Risk Expectantly Managed Pregnant Patients. Am J Perinatol 2023; 40:1725-1731.

Abstract
OBJECTIVES The aim of the study was to identify the characteristics associated with spontaneous labor onset in pregnant patients undergoing expectant management at greater than 39 weeks' gestation and delineate perinatal outcomes associated with spontaneous labor compared with labor induction. STUDY DESIGN This was a retrospective cohort study of singleton pregnancies at ≥390/7 weeks' gestation delivered at a single center in 2013. The exclusion criteria were elective induction, cesarean delivery or presence of a medical indication for delivery at 39 weeks, more than one prior cesarean delivery, and fetal anomaly or demise. We evaluated prenatally available maternal characteristics as potential predictors of the primary outcome-spontaneous labor onset. Multivariable logistic regression was used to generate two parsimonious models: one with and one without third trimester cervical dilation. We also performed sensitivity analysis by parity and timing of cervical examination, and compared the mode of delivery and other secondary outcomes between patients who went into spontaneous labor and those who did not. RESULTS Of 707 eligible patients, 536 (75.8%) attained spontaneous labor and 171 (24.2%) did not. In the first model, maternal body mass index (BMI), parity, and substance use were identified as the most predictive factors. Overall, the model did not predict spontaneous labor (area under the curve [AUC]: 0.65; 95% confidence interval [CI]: 0.61-0.70) with high accuracy. The addition of third trimester cervical dilation in the second model did not significantly improve labor prediction (AUC: 0.66; 95% CI: 0.61-0.70; p = 0.76). These results did not differ by timing of cervical examination or parity. Patients admitted in spontaneous labor had lower odds of cesarean delivery (odds ratio [OR]: 0.33; 95% CI: 0.21-0.53) and neonatal intensive care unit (NICU) admission (OR: 0.38; 95% CI: 0.15-0.94). Other perinatal outcomes were similar between the groups. CONCLUSION Maternal characteristics did not predict spontaneous labor onset at ≥39 weeks' gestation with high accuracy. Patients should be counseled on the challenges of labor prediction regardless of parity and cervical examination, outcomes if spontaneous labor does not occur, and benefits of labor induction. KEY POINTS · Majority of patients will attain spontaneous labor at ≥39 weeks.. · Maternal characteristics do not predict labor at ≥39 weeks.. · Spontaneous labor has associated lower perinatal risks.. · A shared decision model should be utilized in counseling patients who may choose expectant management..

Abstract
OBJECTIVE To compare the labor curve between individuals with induced labor and those undergoing spontaneous labor. METHODS This was a secondary analysis of the Consortium on Safe Labor database, including nulliparous and multiparous individuals with singleton vertex pregnancy who delivered vaginally after spontaneous labor or induction of labor at term. Labor that resulted in uterine rupture and neonates with a 5-minute Apgar scores less than 7, birth injury, or neonatal intensive care unit admission was excluded. We modeled the course of cervical dilation using repeated-measures analysis with a polynomial function. We compared traverse time , defined as the elapsed time between two given dilation measures, between induced and spontaneous labor using interval-censored regression. RESULTS Of 46,835 nulliparous individuals, 18,576 and 28,259 underwent induced and spontaneous labor, respectively. Of 77,503 multiparous individuals, 29,684 and 47,819 underwent induced and spontaneous labor, respectively. The start of the active phase on the labor curve was 6 cm in induced labor, regardless of parity. In nulliparous individuals, induced labor compared with spontaneous labor had a significantly shorter traverse time from 6 to 10 cm (median 1.8 hours [5th-95th percentile 0.4-8.6 hours] vs 2.3 hours [5th-95th percentile 0.6-9.4 hours]; P <.01). In multiparous individuals, induced labor compared with spontaneous labor had a significantly shorter traverse time from 6 to 10 cm (median 0.9 hours [5th-95th percentile 0.1-6.0 hours] vs 1.4 hours [5th-95th percentile 0.3-7.9 hours]; P <.01). CONCLUSION Similar to spontaneous labor, the start of the active phase of induced labor was at 6 cm of dilation. Comparatively, induced labor had a shorter active phase than spontaneous labor. These findings suggest that the current criteria for active phase arrest provided by the American College of Obstetricians and Gynecologists do not need to be lengthened for individuals in induced labor.

Abstract
Anger is an emotional state that occurs when unexpected things happen to or around oneself and is "an emotional state that varies in intensity from mild irritation to intense fury and rage." It is defined as "a strong feeling of displeasure and usually of antagonism," an emotion characterized by tension and hostility arising from frustration, real or imagined injury by another, or perceived injustice. It can manifest itself in behaviors designed to remove the object of the anger (e.g., determined action) or behaviors designed merely to express the emotion. For the Roman philosopher Seneca anger is not an uncontrollable, impulsive, or instinctive reaction. It is, rather, the cognitive assent that such initial reactions to the offending action or words are in fact unjustified. It is, rather, the cognitive assent that such initial reactions to the offending action or words are in fact unjustified. It seems that the year 2022 was a year when many Americans were plainly angry. "Why is everyone so angry?" the New York Times asked in the article "The Year We Lost It." We believe that Seneca is correct in that anger is unacceptable. Anger is a negative emotion that must be controlled, and Seneca provides us with the tools to avoid and destroy anger. Health care professionals will be more effective, content, and happier if they learn more about Seneca's writings about anger and implement his wisdom on anger from over 2000 years ago.

Abstract
OBJECTIVE To evaluate the effect of publication of the ARRIVE (A Randomized Trial of Induction Versus Expectant Management) trial on perinatal outcomes in singleton, term, nulliparous patients. METHODS An interrupted time series analysis was performed using clinical data for nulliparous singleton births at 39 weeks of gestation or later at 13 hospitals in the Northwest region of the United States (January 2016-December 2020). A modified Poisson regression was used to model time trends and changes after the ARRIVE trial (August 9, 2018). Outcomes of interest were elective induction, unplanned cesarean births, hypertensive disorders of pregnancy, a composite of perinatal adverse outcomes, and neonatal intensive care unit admissions. RESULTS The analysis included 28,256 births (15,208 pre-ARRIVE and 13,048 post-ARRIVE). The rate of elective labor induction was 3.6% during the pre-ARRIVE period (January 2016-July 2018) and 10.8% post-ARRIVE (August 2018-December 2020). In the interrupted time series analysis, elective induction increased by 42% (relative risk [RR] 1.42; 95% CI 1.18-1.71) immediately after the ARRIVE trial publication. Thereafter, the trend was unchanged compared with the pre-ARRIVE period. There was no statistically significant change in cesarean birth (RR 0.96; 95% CI 0.89-1.04) or hypertensive disorders of pregnancy (RR 0.91; 95% CI 0.79-1.06) immediately after the trial, and no change in trend. After the ARRIVE trial, there was no immediate change in adverse perinatal outcomes, but a statistically significant increase in trend of adverse perinatal events (1.03; 95% CI 1.01-1.05) when compared with a declining trend observed in the pre-ARRIVE period. CONCLUSION Publication of the ARRIVE trial was associated with an increase in elective induction, and no change in cesarean birth or hypertensive disorders of pregnancy in singleton nulliparous patients giving birth at 39 weeks or later. There was a flattening of the pre-ARRIVE decreasing trend in perinatal adverse events.

Changes in Rates of Hypertensive Disorders of Pregnancy Among Nulliparous Patients After the ARRIVE (A Randomized Trial of Induction Versus Expectant Management) Trial.

Abstract
The ARRIVE (A Randomized Trial of Induction Versus Expectant Management) trial demonstrated lower rates of hypertensive disorders of pregnancy (HDP) among low-risk nulliparous patients undergoing labor induction at 39 weeks of gestation. We conducted a population-based cohort study in which we evaluated the association between the routinization of 39-week induction and the rate of HDP by comparing rates before and after the ARRIVE trial publication, using the National Vital Statistics System. Logistic regression models were used to project what the HDP rate would have been based on trends seen pre-ARRIVE. Despite an overall increase in the rate of HDP from pre-ARRIVE to post-ARRIVE (4.9% pre vs 6.3% post, adjusted odds ratio [aOR] 1.26, 95% CI 1.24-1.27), the HDP rate was significantly lower in the post-ARRIVE group among patients undergoing induction at 39 weeks of gestation (14.7% pre vs 14.1% post, aOR 0.91, 95% CI 0.90-0.93), decreasing by 12.0% per year (P<.001). The rate of HDP among all other delivering patients was higher in the post-ARRIVE group (4.1% pre vs 5.5% post, aOR1.32, 95% CI 1.30-1.34). Our findings may suggest that, as the overall HDP rate rises, the relative advantage of 39-week induction will rise similarly.

JOURNAL OF OBSTETRICS AND GYNAECOLOGY CANADA 2023:S1701-2163(23)00311-0. [PMID: 37105264 DOI: 10.1016/j.jogc.2023.04.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2023] [Revised: 04/05/2023] [Accepted: 04/06/2023] [Indexed: 04/29/2023]
Abstract
OBJECTIVE To evaluate the safety of elective induction at or beyond 39 weeks gestation in the setting of a regional tertiary obstetric care center. METHODS We conducted a prospective cohort feasibility study of low-risk pregnant women who delivered at a regional tertiary obstetric care center. We compared maternal and neonatal outcomes of low risk pregnant women who opted for elective induction at or beyond 39 weeks gestation (n = 112) to a comparison group who opted for expectant management (n = 116). All deliveries occurred between May 1, 2019 and November 30, 2019 and February 15, 2020 and August 15, 2020. RESULTS There were no significant differences in the rates of cesarean deliveries or hypertensive disorders between women who underwent elective induction and those who chose expectant management. There were also no differences in neonatal outcomes. Women in the elective induction group received significantly more cervical ripening agents (p < 0.0001) and had significantly longer stays on the antepartum (p < 0.0001) and labor and delivery units (p = 0.0015) but experienced significantly shorter stays on the postpartum unit (p = 0.0368). There was no difference in total length of hospital stay between groups. CONCLUSION Elective induction protocols can be safely implemented in our regional tertiary obstetric care center without increased risk of maternal complications or neonatal morbidity. Women considering elective induction should be adequately counseled on use of cervical ripening agents and length of stay on antepartum and labor and delivery units.

[PMID: 36642340 DOI: 10.1016/j.ajog.2023.01.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2022] [Revised: 01/08/2023] [Accepted: 01/09/2023] [Indexed: 01/15/2023]
Abstract
BACKGROUND Previous analyses have demonstrated the cost effectiveness of elective induction of labor at 39 weeks of gestation for healthy nulliparous people. However, elective induction of labor is resource intensive, and optimal resource allocation requires a thorough understanding of which subgroups of patients will benefit most. OBJECTIVE This study aimed to determine whether induction of labor at 39 weeks of gestation is more cost-effective in patients with favorable or unfavorable cervical examinations. STUDY DESIGN We constructed 2 decision analysis models using TreeAge software: one modeling induction of labor at 39 weeks of gestation vs expectant management for a group of nulliparous patients with unfavorable cervical examinations and the other modeling induction of labor at 39 weeks of gestation vs expectant management for a group with favorable cervical examinations. Estimates of cost, probability, and health state utility were derived from the literature. Based on previous literature, we assumed that people with favorable cervical examinations would have a lower baseline rate of cesarean delivery and higher rates of spontaneous labor. RESULTS In our base case analysis, induction of labor at 39 weeks of gestation was cost-effective for patients with unfavorable cervical examinations, but not for patients with favorable cervical examinations. The incremental cost per quality-adjusted life year was 50-fold lower for people with unfavorable cervical examinations ($2150 vs $115,100). Induction of labor resulted in 3885 fewer cesarean deliveries and 58 fewer stillbirths per 100,000 patients for those with unfavorable examinations, whereas induction of labor resulted in 2293 fewer cesarean deliveries and 48 fewer stillbirths with labor induction for those with favorable cervical examinations. The results were sensitive to multiple inputs, including the likelihood of cesarean delivery, the cost of induction, the cost of vaginal or cesarean delivery, and the probability of spontaneous labor. In Monte Carlo analysis, the base case findings held true for 64.1% of modeled scenarios for patients with unfavorable cervixes and 55.4% of modeled scenarios for patients with favorable cervixes. CONCLUSION With a willingness-to-pay threshold of $100,000 per quality-adjusted life year, induction of labor at 39 weeks of gestation may be cost-effective for patients with unfavorable cervical examinations, but not for patients with favorable cervical examinations. This result was driven by the likelihood of labor in patients with favorable cervical examinations, and the resultant avoidance of prolonged pregnancy and its complications, including hypertensive disorders of pregnancy and stillbirths. Health systems may wish to prioritize patients with unfavorable cervical examinations for elective induction of labor at 39 weeks of gestation, which may be opposite to common practice.
