RESUMEN

OBJECTIVE: To determine intrapartum factors associated with perineal laceration at delivery. METHODS: This was a planned secondary analysis of a multicenter randomized clinical trial of delayed versus immediate pushing among term nulliparous women in labor with neuraxial analgesia conducted in the United States. Intrapartum characteristics were extracted from the medical charts. The primary outcome was perineal laceration, defined as second degree or above, characterized at delivery in women participating in longer term pelvic floor assessments post-delivery. Multivariable logistic regression was used to refine risk estimates while adjusting for randomization group, birth weight, and maternal age. RESULTS: Among the 941 women participating in the pelvic floor follow-up, 40.6% experienced a perineal laceration. No first stage labor characteristics were associated with perineal laceration, including type of labor or length of first stage. Receiving an amnioinfusion appeared protective of perineal laceration (adjusted odds ratio, 0.48; 95% confidence interval 0.26-0.91; P = 0.01). Second stage labor characteristics associated with injury were length of stage (2.01 h vs. 1.50 h; adjusted odds ratio, 1.36; 95% confidence interval 1.18-1.57; P < 0.01) and a prolonged second stage (adjusted odds ratio, 1.64; 95% confidence interval 1.06-2.56; P < 0.01). Operative vaginal delivery was strongly associated with perineal laceration (adjusted odds ratio, 3.57; 95% confidence interval 1.85-6.90; P < 0.01). CONCLUSION: Operative vaginal delivery is a modifiable risk factor associated with an increased risk of perineal laceration. Amnioinfusion appeared protective against injury, which could reflect a spurious finding, but may also represent true risk reduction similar to the mechanism of warm perineal compress.

RESUMEN

BACKGROUND: Childbirth education can help pregnant individuals feel in control, relieve anxiety and fear, and decrease pain perception. However, many barriers exist that impede patients from obtaining adequate childbirth education, especially in the era of the COVID-19 pandemic. Advances in technology, such as podcasts, can allow for asynchronous patient education. OBJECTIVE: This study aimed to assess the effect of a labor education podcast on personal perception of control and patient satisfaction during childbirth. STUDY DESIGN: This was a randomized controlled trial that included nulliparous, low-risk women with singleton gestations who reached 36 weeks' gestation at 2 academic hospitals in Philadelphia, Pennsylvania. Participants were randomized at 28 weeks and 0 days of gestation to usual education (control) or podcast education (intervention), which included links to 7 labor-related podcast episodes on patient-suggested topics that were available on widely-used podcatchers. Primary outcomes were assessed with a 3-question birth satisfaction survey and the Labour Agentry Scale to evaluate personal perception of control during childbirth. Secondary outcomes included the Edinburgh Postnatal Depression Scale score. Analyses were performed as intention-to-treat. Parametric and nonparametric data were compared using the Student t-test or Wilcoxon rank-sum test, as appropriate. RESULTS: A total of 201 women were randomized, and 153 were included in the final analysis (78 in podcast and 75 in control group). There were no significant differences in maternal demographics. Patients in the podcast group had higher median birth satisfaction scores compared with the control group (20 [18-21] vs 18 [16-21]; P=.002), without a significant difference in median Labour Agentry Scale scores (57 [50-63] vs 54 [47-62]; P=.12). When restricting analysis to patients who underwent induction, Labour Agentry Scale scores were significantly higher in the podcast group (58 [53-64] vs 54 [47-61]; P=.045), representing an increased perception of control. However, birth satisfaction score was not different between the groups (P=.06). The most downloaded podcasts were on induction and labor anesthesia. More than 95% of participants would recommend the podcasts to family and friends. CONCLUSION: An educational podcast on labor topics was well-received, increased patient satisfaction overall, and increased labor agentry among those who were induced. Podcasts are a promising educational modality to improve patient experience during childbirth, and warrant further exploration.

RESUMEN

BACKGROUND: Implementation outcomes, including acceptability, are of critical importance in both implementation research and practice. The gold standard measure of acceptability, Acceptability of Intervention Measure (AIM), skews positively with a limited range. In an ongoing hybrid effectiveness-implementation trial, we aimed to evaluate clinician acceptability of induction standardization. Here, we describe an innovative mixed-methods approach to maximize the interpretability of the AIM using a case study in maternal health. METHODS: In this explanatory sequential mixed methods study, we distributed the validated, 4-question AIM (total 4-20) to labor and delivery clinicians 6 months post-implementation at 2 sites (Site 1: 3/2021; Site 2: 6/2021). Respondents were grouped by total score into tertiles. The top ("High" Acceptability) and bottom ("Low" Acceptability) tertiles were invited to participate in a 30-minute semi-structured qualitative interview from 6/2021 to 10/2021 until thematic saturation was reached in each acceptability group. Participants were purposively sampled by role and site. Interviews were coded using an integrated approach, incorporating a priori attributes (Consolidated Framework for Implementation Research constructs) into a modified content analysis approach. RESULTS: 104 clinicians completed the initial survey; 24 were interviewed (12 "High" and 12 "Low" Acceptability). Median total AIM scores were 20/20 IQR[20-20] in the High and 12.5/20 IQR[11-14] in the Low Acceptability groups. In both groups, clinicians were enthusiastic about efforts to standardize labor induction, believing it reduces inter-clinician variability and improves equitable, evidence-based care. In the Low Acceptability group, clinicians stated the need for flexibility and consideration for patient uniqueness. Rarely, clinicians felt labor induction could not or should not be standardized, citing discomfort with medicalization of labor, and concerns with "bulldozing" the patient with interventions. Suggested strategies for overcoming negative sentiment included comprehensive clinician education, as well as involving patients as active participants in the protocol prenatally. CONCLUSIONS: This study utilized AIM in an innovative sequential mixed-methods approach to characterize clinician acceptability, which may be generalizable across implementation endeavors. By performing this work during a hybrid trial, implementation strategies to improve acceptability emerged (clinician education focusing on respect for flexibility; involving patients as active participants prenatally) for year 2, which will inform future multi-site work.

RESUMEN

OBJECTIVE: We aimed to describe hemoglobin (Hb) change after transfusion in the nonacute postpartum anemic population in order to provide clinicians with appropriate expectations regarding Hb rise posttransfusion. STUDY DESIGN: We performed a secondary analysis of a randomized controlled trial comparing initial transfusion with 1 unit of packed red blood cells (pRBCs) to 2 units pRBCs for postpartum women requiring nonacute transfusion (n = 66). Inclusion criteria were: age 18 years and older, Hb level either <7 g/dL or >7 g/dL with signs or symptoms of anemia, and > 6 hours postpartum without contraindication to transfusion. Hb assessment was performed 4 to 6 hours after initial transfusion. Hb change (ΔHb) was calculated as posttransfusion Hb minus randomization Hb. Our primary goal was to describe mean ΔHb per pRBC transfused at the 4- to 6-hour posttransfusion blood count. We also compared ΔHb per pRBC transfused by number of units transfused, body mass index (BMI), and symptoms (dizziness and/or fatigue) at time of posttransfusion assessment. RESULTS: Participants were mean age 29, mean BMI of 27, and over 70% self-identified as black, 12% identified as white, and 9% as Asian race. Mean Hb prior to transfusion was 6.9 ± 0.6 g/dL. Mean ΔHb per pRBC transfused was 0.9 ± 0.4g/dL. There was no difference in ΔHb per pRBC by BMI category (normal weight < 25 kg/m2: 1.1 ± 0.2 g/dL; overweight 25-29.9 kg/m2: 0.9 ± 0.5 g/dL; obese ≥ 30 kg/m2: 0.9 ± 0.5 g/dL; p = 0.12). Finally, there was also no significant difference in ΔHb per pRBC by whether or not symptoms of anemia persisted after initial transfusion (1.0 ± 0.7 vs. 0.9 ± 0.4 g/dL, p = 0.39). CONCLUSION: Our data supports the classically accepted rise in Hb after pRBC of approximately 1 g/dL, regardless of BMI category or anemia symptomatology. The study population includes patients at highest risk of postpartum anemia. The results of our study provide important information for clinicians caring for postpartum patients with nonacute anemia. KEY POINTS: · Postpartum anemia is a significant public health issue.. · Providers use hemoglobin change to assess response to blood transfusion.. · The established 1 g/dL change in Hb after transfusion is based on historic surgical populations.. · Our data suggests the 1 g/dL Hb change is applicable to postpartum patients..

RESUMEN

Hospital labor and delivery floors frequently operate like intensive care units (ICUs)-with continuous data feeds pouring into central monitoring stations against a background of blaring alarms. Yet the majority of obstetric patients are healthy and do not require ICU-level care. Despite limited organizational recommendations guiding the frequency of vital sign measurement, continuous pulse oximetry is used widely for laboring patients. There is also no evidence that morbidity prevention is linked to specific frequencies of vital sign monitoring in low-risk patients. In fact, studies examining the performance of maternal early warnings systems based on vital signs suggest that these may not reliably provide actionable information regarding maternal physiologic status. Furthermore, it is very possible that intrapartum maternal overmonitoring can impact care negatively by generating alarm fatigue, causing providers to miss actual abnormal vital signs that may precede morbidity. KEY POINTS: · Labor and delivery units may engage in maternal physiologic overmonitoring.. · Overmonitoring increases risk for alarm fatigue.. · Deimplementing low-value care may improve obstetric outcomes..

RESUMEN

OBJECTIVE: The objective of this study is to examine risk factors and adverse outcomes related to preeclampsia with severe features complicated by pulmonary edema. STUDY DESIGN: This is a nested case-control study of all patients with preeclampsia with severe features who delivered in a tertiary, urban, academic medical center over a 1-year period. The primary exposure was pulmonary edema and the primary outcome was a composite of severe maternal morbidity (SMM), defined according to the Centers for Disease Control and Prevention and based on International Classification of Diseases, 10th revision, Clinical Modification codes. Secondary outcomes included postpartum length of stay, maternal intensive care unit admission, 30-day readmission, and discharge on antihypertensive medication. A multivariable logistic regression model adjusting for clinical characteristics related to the primary outcome was used to determine adjusted odds ratios (aOR) as measures of effect. RESULTS: Of 340 patients with severe preeclampsia, there were seven cases of pulmonary edema (2.1%). Pulmonary edema was associated with lower parity, autoimmune disease, earlier gestational age at diagnosis of preeclampsia and at delivery, and cesarean section. Patients with pulmonary edema demonstrated increased odds of SMM (aOR: 10.11, 95% confidence interval [CI]: 2.13-47.90), extended postpartum length of stay (aOR: 32.56, 95% CI: 3.95-268.45), and intensive care unit admission (aOR: 102.85, 95% CI: 7.43-1422.92) compared with those without pulmonary edema. CONCLUSION: Pulmonary edema is associated with adverse maternal outcomes among patients with severe preeclampsia, and is more likely to affect patients who are nulliparous, have an autoimmune disease, and are diagnosed preterm. KEY POINTS: · Pulmonary edema increases odds of severe maternal morbidity in preeclamptics.. · Pulmonary edema prolongs postpartum and intensive care unit stay in preeclamptics.. · Risk factors for pulmonary edema include nulliparity and autoimmune disease.. · Earlier diagnosis of severe preeclampsia increases risk of pulmonary edema..

RESUMEN

OBJECTIVE: Our prior work demonstrated decreased birth satisfaction for Black women undergoing labor induction. We aimed to determine if implementation of standardized counseling around calculated cesarean risk during labor induction could reduce racial disparities in birth satisfaction. STUDY DESIGN: We implemented use of a validated calculator that provides an individual cesarean risk score for women undergoing induction into routine care. This prospective cohort study compared satisfaction surveys for 6 months prior to implementation (preperiod: January 2018-June 2018) to 1 year after (postperiod: July 2018-June 2019). Women with full-term (≥37 weeks) singleton gestations with intact membranes and an unfavorable cervix undergoing induction were included. In the postperiod, providers counseled patients on individual cesarean risk at the beginning of induction using standardized scripts. This information was incorporated into care at patient-provider discretion. The validated 10-question Birth Satisfaction Scale-Revised (BSS-R) subdivided into three domains was administered throughout the study. Patients were determined to be "satisfied" or "unsatisfied" if total BSS-R score was above or below the median, respectively. In multivariable analysis, interaction terms evaluated the differential impact of the calculator on birth satisfaction by race (Black vs. non-Black women). RESULTS: A total of 1,008 of 1,236 (81.6%) eligible women completed the BSS-R (preperiod: 330 [79.7%] versus postperiod: 678 [82.5%], p = 0.23), 63.8% of whom self-identified as Black. In the preperiod, Black women were 50% less likely to be satisfied than non-Black women, even when controlling for differences in parity (Black: 39.0% satisfied vs. non-Black: 53.9%, adjusted odds ratio [aOR] = 0.49, 95% confidence interval [CI]: 0.30-0.79). In the postperiod, there was no difference in satisfaction by race (Black: 43.7% satisfied vs. non-Black: 44.0%, aOR = 0.97. 95% CI: 0.71-1.33). Therefore, disparities in birth satisfaction were no longer present at postimplementation (interaction p = 0.03). CONCLUSION: Implementation of standardized counseling with a validated calculator to predict cesarean risk after labor induction is associated with a decrease in racial disparities in birth satisfaction. KEY POINTS: · Preintervention, Black women were less likely to have above-median birth satisfaction.. · We implemented standardized counseling around cesarean risk with labor induction.. · Implementation was associated with reduced racial disparities in birth satisfaction scores..

RESUMEN

OBJECTIVE: The aim of the study is to determine the relationship between a hospital's provision of subspecialty neonatal and maternal care. Specifically, we sought to understand where women with high-risk maternal conditions received intrapartum care and estimate the potential transfer burden for those with maternal high-risk conditions delivering at hospitals without subspecialty maternal care. STUDY DESIGN: This is a descriptive study using data from 2015 State Inpatient Databases and the American Hospital Association Annual Survey. Characteristics were compared between hospitals based on the concordance of their maternal and neonatal care. The incidences of high-risk maternal conditions (pre-eclampsia with severe features, placenta previa with prior cesarean delivery, cardiac disease, pulmonary edema, and acute liver failure) were compared. To determine the potential referral burden, the percent of women with high-risk conditions delivering at a hospital without subspecialty maternal care but delivering in a county with a hospital with subspecialty maternal care was calculated. RESULTS: The analysis included 486,398 women who delivered at 544 hospitals, of which 104 (19%) and 182 (33%) had subspecialty maternal and neonatal care, respectively. Ninety-eight hospitals provided both subspecialty maternal and neonatal care; however, 84 hospitals provided only subspecialty neonatal care but no subspecialty maternal care. Among high-risk maternal conditions examined, approximately 65% of women delivered at a hospital with subspecialty maternal care. Of the remainder who delivered at a hospital without subspecialty maternal care, one-third were in a county where subspecialty care was present. For women with high-risk conditions who delivered in a county without subspecialty maternal care, the median distance to the closest county with subspecialty care was 52.8 miles (IQR: 34.3-87.7 miles). CONCLUSION: Approximately 50% of hospitals with subspecialty neonatal care do not provide subspecialty maternal care. This discordance may present a challenge when both high-risk maternal and neonatal conditions are present. KEY POINTS: · High-risk women who deliver at hospitals without subspecialty care are in more rural areas.. · Approximately 50% of hospitals with subspecialty neonatal care do not provide subspecialty maternal care.. · This discordance may present a challenge when both high-risk maternal and neonatal conditions are present..

RESUMEN

OBJECTIVE: Health care providers and health systems confronted new challenges to deliver timely, high-quality prenatal care during the coronavirus disease 2019 (COVID-19) pandemic as the pandemic raised concerns that care would be delayed or substantively changed. This study describes trends in prenatal care delivery in 2020 compared with 2018 to 2019 in a large, commercially insured population and investigates changes in obstetric care processes and outcomes. STUDY DESIGN: This retrospective cohort study uses de-identified administrative claims for commercially insured patients. Patients whose entire pregnancy took place from March 1 to December 31 in years 2018, 2019, and 2020 were included. Trends in prenatal care, including in-person, virtual, and emergency department visits, were evaluated, as were prenatal ultrasounds. The primary outcome was severe maternal morbidity (SMM). Secondary outcomes included preterm birth and stillbirth. To determine whether COVID-19 pandemic-related changes in prenatal care had an impact on maternal outcomes, we compared the outcome rates during the pandemic period in 2020 to equivalent periods in 2018 and 2019. RESULTS: In total, 35,112 patients were included in the study. There was a significant increase in the prevalence of telehealth visits, from 1.1 to 1.2% prior to the pandemic to 17.2% in 2020, as well as a significant decrease in patients who had at least one emergency department visit during 2020. Overall prenatal care and ultrasound utilization were unchanged. The rate of SMM across this period was stable (2.3-2.8%) with a statistically significant decrease in the preterm birth rate in 2020 (7.4%) compared with previous years (8.2-8.6%; p < 0.05) and an unchanged stillbirth rate was observed. CONCLUSION: At a time when many fields of health care were reshaped during the pandemic, these observations reveal considerable resiliency in both the processes and outcomes of obstetric care. KEY POINTS: · Overall prenatal care and ultrasound were unchanged from 2018 to 2019 to 2020.. · There was a large increase in the prevalence of telehealth visits in 2020.. · There was no change in the rate of severe maternal morbidity or stillbirth in 2020 compared with 2018 to 2019..

RESUMEN

OBJECTIVE: This study aimed to evaluate maternal and neonatal outcomes by method of cervical ripening for labor induction among low-risk nulliparous individuals. STUDY DESIGN: This is a secondary analysis of a multicenter randomized trial of labor induction at 39 weeks versus expectant management in low-risk nulliparous participants. Participants undergoing cervical ripening for labor induction in either group were included. Participants were excluded for preripening membrane rupture, abruption, chorioamnionitis, fetal demise, or cervical dilation ≥3.5 cm. Cervical ripening was defined by the initial method used: prostaglandin only (PGE; referent), Foley with concurrent prostaglandin (Foley-PGE), Foley only (Foley), and Foley with concurrent oxytocin (Foley-oxytocin). Coprimary outcomes were adverse maternal and neonatal composites. Secondary outcomes included cesarean delivery and length of labor and delivery (L&D) stay. Multivariable analysis was used to adjust for patient characteristics. RESULTS: Of 6,106 participants included in the trial, 2,376 (38.9%) met criteria for this analysis. Of these, 1,247 (52.4%) had cervical ripening with PGE, 290 (12.2%) had Foley-PGE, 385 (16.2%) had Foley, and 454 (19.1%) had Foley-oxytocin. The maternal composite outcome was similar among participants who received Foley-PGE (24.1%, adjusted relative risk [aRR] = 1.21, 95% confidence interval [CI]: 0.96-1.52), Foley (21.3%, aRR = 1.16, 95% CI: 0.92-1.45), or Foley-oxytocin (19.4%, aRR = 1.04, 95% CI: 0.83-1.29), compared with PGE (19.7%). The neonatal composite outcome was less frequent in participants who received the Foley-PGE (2.4%, aRR = 0.35, 95% CI: 0.16-0.75) or Foley (3.6%, aRR = 0.51, 95% CI: 0.29-0.89) but did not reach statistical significance for participants who received Foley-oxytocin (4.6%, aRR = 0.63, 95% CI: 0.40-1.01) compared with PGE only (6.8%). Participants who received Foley-PGE or Foley-oxytocin had a shorter L&D stay (adjusted mean difference = -1.97 hours, 95% CI: -3.45 to -0.49 and -5.92 hours, 95% CI: -7.07 to -4.77, respectively), compared with PGE. CONCLUSION: In term low-risk nulliparous participants, Foley alone or concurrent with PGE is associated with a lower risk of adverse neonatal outcomes than with PGE alone. Length of L&D stay was the shortest with concurrent Foley-oxytocin. KEY POINTS: · Adverse maternal outcomes are similar among different methods of cervical ripening in low-risk women.. · Adverse neonatal outcomes are less frequent with use of Foley alone or in combination with PGE.. · The use of Foley alone, or in combination with other agents, appears to be beneficial..

RESUMEN

BACKGROUND: Evidence of detachment of the levator ani muscle system is seen more frequently in patients with pelvic floor disorders. It has been suggested that passive descent of the fetus before pushing could be used to decrease operative vaginal delivery and levator ani muscle injury. OBJECTIVE: This planned analysis aimed to determine whether immediate or delayed pushing was associated with an increased proportion of injury to the levator ani muscle system after the first delivery among nulliparous women. STUDY DESIGN: The Optimizing Management of the Second Stage study was a multicenter randomized trial. Nulliparous women with term pregnancies and neuraxial analgesia were randomly assigned at complete cervical dilation to either immediate pushing or delayed pushing for 1 hour. A subset of participants consented to longitudinal objective pelvic floor assessments: (1) during postpartum stay (initial), (2) at 6 weeks (postpartum 1), and (3) at 6 months (postpartum 2) with transperineal 3-dimensional ultrasound. Following the completion of all visits by all subjects, saved 3-dimensional ultrasound volumes were assessed in a masked fashion. The outcome was "occult" levator ani muscle injury on the right or left, defined as a widening of the attachment of the levator ani to its origin utilizing the levator-urethra gap measurement. Measurements and proportions were compared between the 2 groups by study visit using the χ2 test or Fisher exact test for categorical variables and the t test or Mann-Whitney U test for continuous variables as appropriate. RESULTS: Here, 941 of 2414 randomized subjects (39.0%) participated in the pelvic floor assessments: 452 in the immediate pushing group and 489 in the delayed pushing group. We obtained sonograms on 67%, 83%, and 77% of the pelvic floor assessment participants at the initial, postpartum 1, and postpartum-2 visits, respectively. Demographic and labor characteristics were comparable between the 2 groups; 94% of participants were non-Hispanic, and 50% of participants were Black. Levator ani muscle injury was noted in 77 participants (13.6%) at the initial visit, 99 (13.1%) at PP1, and 72 (10.6%) at PP2. There was no difference in injury between women in the immediate pushing group and women in the delayed pushing group. These findings did not change when the threshold (sensitivity) of levator ani muscle injury was adjusted to a less conservative measure. CONCLUSION: Among nulliparous women at term with neuraxial analgesia, the rates of occult levator ani muscle injury were not different between women undergoing immediate pushing and women undergoing delayed pushing in the second stage of labor. Further research efforts are needed to understand the development and potential prevention of subsequent pelvic floor disorders.

RESUMEN

OBJECTIVE: To evaluate whether hypertensive disorders of pregnancy (HDP) among low-risk nulliparous women expectantly managed at or after 39 weeks of gestation are associated with adverse outcomes. DESIGN: Secondary analysis of a randomised trial. SETTING: Multicentre, USA. POPULATION: Individuals in the expectantly managed group who delivered on or after 39 weeks. METHODS: Multivariable analysis to estimate adjusted relative risks (aRR) for binomial outcomes, adjusted odds ratios (aOR) for multinomial outcomes and 95% CI. MAIN OUTCOME MEASURES: Composite adverse maternal outcome including placental abruption, pulmonary oedema, postpartum haemorrhage, postpartum infection, venous thromboembolism or intensive care unit admission. Secondary outcomes included a composite of perinatal death or severe neonatal complications, mode of delivery, small and large for gestational age and neonatal intermediate or intensive unit length of stay. RESULTS: Of the 3044 women randomised to expectant management in the original trial, 2718 (89.3%) were eligible for this analysis, of whom 373 (13.7%) developed HDP. Compared with participants who remained normotensive, those who developed HDP were more likely to experience the maternal composite (12% versus 6%, aRR 1.84, 95% CI 1.33-2.54) and caesarean delivery (29% versus 23%, aOR 1.32, 95% CI 1.01-1.71). Differences between the two groups were not significantly different for the adverse perinatal composite (7% versus 5%, aRR 1.38, 95% CI 0.92-2.07) or for other secondary outcomes. CONCLUSION: Almost 14% of low-risk nulliparous individuals expectantly managed at 39 weeks developed HDP, and were more likely to experience adverse maternal outcomes compared with those who did not develop HDP. TWEETABLE ABSTRACT: Almost 14% of low-risk nulliparous individuals expectantly managed at 39 weeks developed hypertensive disorders of pregnancy, and were more likely to experience adverse maternal outcomes compared with those who did not develop hypertensive disorders.

RESUMEN

The coincidence of a global pandemic with 21st-century telecommunication technology has led to rapid deployment of virtual obstetric care beginning in March of 2020. Pregnancy involves uniquely time-sensitive health care that may be amenable to restructuring into a hybrid of telemedicine and traditional visits to optimize accessibility and outcomes. The coronavirus disease 2019 pandemic has provided an unprecedented natural laboratory to explore how virtual obstetric care programs can be developed, implemented, and maintained, both as a contingency model for the pandemic and potentially for the future. Here, we discuss the role of telehealth and virtual care for pregnancy management in the coronavirus disease 2019 pandemic, as well as anticipated barriers, challenges, and strategies for success for obstetric telemedicine.

RESUMEN

BACKGROUND: The perinatal and maternal consequences of induction of labor at 39 weeks among low-risk nulliparous women are uncertain. METHODS: In this multicenter trial, we randomly assigned low-risk nulliparous women who were at 38 weeks 0 days to 38 weeks 6 days of gestation to labor induction at 39 weeks 0 days to 39 weeks 4 days or to expectant management. The primary outcome was a composite of perinatal death or severe neonatal complications; the principal secondary outcome was cesarean delivery. RESULTS: A total of 3062 women were assigned to labor induction, and 3044 were assigned to expectant management. The primary outcome occurred in 4.3% of neonates in the induction group and in 5.4% in the expectant-management group (relative risk, 0.80; 95% confidence interval [CI], 0.64 to 1.00). The frequency of cesarean delivery was significantly lower in the induction group than in the expectant-management group (18.6% vs. 22.2%; relative risk, 0.84; 95% CI, 0.76 to 0.93). CONCLUSIONS: Induction of labor at 39 weeks in low-risk nulliparous women did not result in a significantly lower frequency of a composite adverse perinatal outcome, but it did result in a significantly lower frequency of cesarean delivery.

RESUMEN

BACKGROUND: Maternal mortality is higher among Black than White people in the United States. Whether Black-White disparities in maternal in-hospital mortality during the delivery hospitalization vary across hospital types (Black-serving vs nonBlack-serving and teaching vs nonteaching) and whether overall maternal mortality differs across hospital types is not known. OBJECTIVE: The aims of this study were to determine whether risk-adjusted Black-White disparities in maternal mortality during the delivery hospitalization vary by hospital types (this is analysis of disparities in mortality within hospital types) and compare risk-adjusted in-hospital maternal mortality among Black-serving and nonBlack-serving teaching and nonteaching hospitals regardless of race (this is an analysis of overall mortality across hospital types). STUDY DESIGN: We performed a population-based, retrospective cohort study of 5,679,044 deliveries among Black (14.2%) and White patients (85.8%) in 3 states (California, Missouri, and Pennsylvania) from 1995 to 2009. A hospital discharge disposition of "death" defined maternal in-hospital mortality. Black-serving hospitals had at least 7% Black obstetrical patients (top quartile). We performed risk adjustment by calculating expected death rates using predictions from logistic regression models incorporating sociodemographics, rurality, comorbidities, multiple gestations, gestational age at delivery, year, state, and mode of delivery. We calculated risk-adjusted risk ratios of mortality by comparing observed-to-expected ratios among Black and White patients within hospital types and then examined mortality across hospital types, regardless of patient race. We quantified the proportion of Black-White disparities in mortality attributable to delivering in Black-serving hospitals using causal mediation analysis. RESULTS: There were 330 maternal deaths among 5,679,044 patients (5.8 per 100,000). Black patients died more often (11.5 per 100,000) than White patients (4.8 per 100,000) (relative risk, 2.38; 95% confidence interval, 1.89-2.98). Examination of Black-White disparities revealed that after risk adjustment, Black patients had significantly greater risk of death (adjusted relative risk, 1.44; 95% confidence interval, 1.17-1.79) and that the disparity was similar within each of the hospital types. Comparison of mortality, regardless of race, across hospital types revealed that among teaching hospitals, mortality was similar in Black-serving and nonBlack-serving hospitals. However, among nonteaching hospitals, mortality was significantly higher in Black-serving vs nonBlack-serving hospitals (adjusted relative risk, 1.47; 95% confidence interval, 1.15-1.87). Notably, 53% of Black patients delivered in nonteaching, Black-serving hospitals compared with just 19% of White patients. Among nonteaching hospitals, 47% of Black-White disparities in maternal in-hospital mortality were attributable to delivering at Black-serving hospitals. CONCLUSION: Maternal in-hospital mortality during the delivery hospitalization among Black patients is more than double that of White patients. Our data suggest this disparity is caused by excess mortality among Black patients within each hospital type, in addition to excess mortality in nonteaching, Black-serving hospitals where most Black patients deliver. Addressing downstream effects of racism to achieve equity in maternal in-hospital mortality will require transparent reporting of quality metrics by race to reduce differential care and outcomes within hospital types, improvements in care delivery at Black-serving hospitals, overcoming barriers to accessing high-quality care among Black patients, and eventually desegregation of healthcare.

RESUMEN

BACKGROUND: The American Academy of Blood Banks recommends single-unit red cell transfusion protocols across medicine to reduce transfusion complications and the use of a scarce resource. There are minimal data regarding single-unit protocols in obstetrics. OBJECTIVE: We aimed to compare single-unit vs multiple-unit transfusion protocols for treatment of hemodynamically stable postpartum anemia. STUDY DESIGN: We performed a randomized trial comparing initial transfusion with 1 unit of packed red blood cells (single-unit protocol) to 2 units of packed red blood cells (multiple-unit protocol) from March 2018 to July 2019. Women who required transfusion >6 hours postpartum were approached for consent. Unstable vital signs, hemoglobin level <5 g/dL, hemoglobinopathy, and cardiomyopathy were exclusion criteria for enrollment. Hemoglobin assessment and standardized clinical evaluation were performed 4 to 6 hours posttransfusion; additional packed red blood cells were given if indicated. The primary outcome was total units transfused. Secondary outcomes included length of stay, endometritis, wound separation or infection, venous thromboembolism, and intensive care unit admission within 30 days postpartum. Breastfeeding, depression, maternal attachment, and fatigue scores were assessed at 4 to 9 weeks postpartum. A total of 66 women were required to detect a 20% reduction in units transfused with a single-unit protocol (power=80%; α=0.05). RESULTS: A total of 66 women were randomized (33 per arm). There were no differences between groups in demographic or clinical characteristics, including delivery mode, blood loss, and randomization hemoglobin levels. The mean number of units transfused was lower in the single-unit protocol than in the multiple-unit protocol (1.2 U vs 2.1 U; P<.001). Only 18.2% of women in the single-unit arm required additional packed red blood cells. At posttransfusion assessment, women in the single-unit arm had lower hemoglobin levels (7.8 g/dL vs 8.7 g/dL; P<.001), but there were no differences in vital signs or symptoms between groups. There were also no differences in length of stay, 30-day complications, or 4 to 9 week postpartum outcomes. CONCLUSION: In women with hemodynamically stable postpartum anemia, a single-unit protocol avoided a second unit of packed red blood cells in >80% of women without significant impact on morbidity. Our work supports the use of single-unit initial transfusion in this population.

RESUMEN

Following a collaborative workshop at the 39th Annual Pregnancy Meeting, the Society for Maternal-Fetal Medicine Reproductive Health Advisory Group identified a need to assess the attitudes of maternal-fetal medicine subspecialists about abortion services and the available resources at the local and regional levels. The purpose of this study was to identify trends in attitudes, beliefs, and behaviors of practicing maternal-fetal medicine subspecialists in the United States regarding abortion. An online survey was distributed to associate and regular members of the Society for Maternal-Fetal Medicine to assess their personal training experience, abortion practice patterns, factors that influence their decision to provide abortion care, and their responses to a series of scenarios about high-risk maternal or fetal medical conditions. Frequencies were analyzed and univariable and multivariable analyses were conducted on the survey responses. Of the 2751 members contacted, 546 Society for Maternal-Fetal Medicine members completed all (448 of 546, 82.1%) or some (98 of 546, 17.9%) of the survey. More than 80% of the respondents reported availability of abortion services in their state, 70% reported availability at their primary institution, and 44% reported provision as part of their personal medical practice. Ease of referral to family planning subspecialists or other abortion providers, institutional restrictions, and the lack of training or continuing education were identified as the most significant factors contributing to the respondents' limited scope of abortion services or lack of any abortion services offered. In the univariable analysis, exposure to formal family planning training programs, fewer years since the completion of residency, current practice setting not being religiously affiliated, and current state categorized as supportive by the Guttmacher Institute's abortion policy landscape were factors associated with abortion provision (all P values <.01). After controlling for these factors in a multivariable regression, exposure to formal family planning training programs was no longer associated with current abortion provision (P=.20; adjusted odds ratio, 1.34; 95% confidence interval, 0.85-2.10), whereas a favorable state policy environment and fewer years since the completion of residency remained associated with abortion provision. The results of this survey suggest that factors at the individual, institutional, and state levels affect the provision of abortion care by maternal-fetal medicine subspecialists. The subspecialty of maternal-fetal medicine should be active in ensuring adequate training and education to create a community of maternal-fetal medicine physicians able to provide comprehensive reproductive healthcare services.

RESUMEN

BACKGROUND: The goal of regionalized perinatal care, specifically levels of maternal care, is to improve maternal outcomes through risk-appropriate obstetric care. Studies of levels of maternal care are limited by current approaches to identify a hospital's level of care, often relying on hospital self-reported data, which is expensive and challenging to collect and validate. The study objective was to develop an empiric approach to determine a hospital's level of maternal care using administrative data reflective of the patient care provided and apply this approach to describe the levels of maternal care available over time. METHODS: Retrospective cohort study of mother-infant dyads who delivered in California, Missouri, and Pennsylvania hospitals from 2000 to 2009. Linked mother-infant administrative records with an infant born at 24-44 weeks' gestation and a birth weight of 400-8000 g were included. Using the American College of Obstetricians and Gynecologists and the Society for Maternal Fetal Medicine descriptions of levels of maternal care, four levels were classified based on the appropriate location of care for patients with specific medical or pregnancy conditions. Individual hospitals were assigned a level of maternal care annually based on the volume of patients who delivered reflective of the four classified levels as determined by International Classification of Diseases and Current Procedural Terminology. RESULTS: Based on the included 6,895,000 mother-infant dyads, the obstetric hospital levels of maternal care I, II, III and IV were identified. High-risk patients more frequently delivered in hospitals with higher level maternal care, accounting for 8.9, 10.9, 13.8, and 16.9% of deliveries in level I, II, III and IV hospitals, respectively. The total number of obstetric hospitals decreased over the study period, while the proportion of hospitals with high-level (level III or IV) maternal care increased. High-level hospitals were located in more densely populated areas. CONCLUSION: Identification of the level of maternal care, independent of hospital self-reported variables, is feasible using administrative data. This empiric approach, which accounts for changes in hospitals over time, is a valuable framework for perinatal researchers and other stakeholders to inexpensively identify measurable benefits of levels of maternal care and characterize where specific patient populations receive care.

RESUMEN

OBJECTIVE: This study was aimed to evaluate opioid use after cesarean delivery (CD) and to assess implementation of an enhanced recovery after CD (ERAS-CD) pathway and its association with inpatient and postdischarge pain control and opioid use. STUDY DESIGN: We conducted a baseline survey of women who underwent CD from January to March 2017 at a single, urban academic hospital. Patients were called 5 to 8 days after discharge and asked about their pain and postdischarge opioid use. An ERAS-CD pathway was implemented as a quality improvement initiative, including use of nonopioid analgesia and standardization of opioid discharge prescriptions to ≤25 tablets of oxycodone of 5 mg. From November to January 2019, a postimplementation survey was conducted to assess the association between this initiative and patients' pain control and postoperative opioid use, both inpatient and postdischarge. RESULTS: Data were obtained from 152 women preimplementation (PRE) and 137 women post-implementation (POST); complete survey data were obtained from 102 women PRE and 98 women POST. The median inpatient morphine milligram equivalents consumed per patient decreased significantly from 141 [range: 90-195] PRE to 114 [range: 45-168] POST (p = 0.002). On a 0- to 10-point scale, median patient-reported pain scores at discharge decreased significantly (PRE: 7 [range: 5-8] vs. POST 5 [range: 3-7], p < 0.001). The median number of pills consumed after discharge also decreased significantly (PRE: 25 [range: 16-30] vs. POST 17.5 [range: 4-25], p = 0.001). The number of pills consumed was significantly associated with number prescribed (p < 0.001). The median number of leftover pills and number of refills did not significantly differ between groups. Median patient-reported pain scores at the week after discharge were lower in the POST group (PRE: 4 [range: 2-6] vs. POST 3[range: 1-5], p = 0.03). CONCLUSION: Implementing an ERAS-CD pathway was associated with a significant decrease in inpatient and postdischarge opioid consumption while improving pain control. Our data suggest that even fewer pills could be prescribed for some patients. KEY POINTS: · An ERAS-CD pathway was associated with decreased opioid use.. · Outpatient opioid consumption after cesarean warrants further study.. · Physician prescribing drives patients' opioid consumption..

RESUMEN

OBJECTIVE: Studies demonstrate shorter time to delivery with concurrent use of misoprostol and cervical Foley catheter. However, concurrent placement may not be feasible. If misoprostol is used to start an induction, little is known regarding the benefit of sequentially using Foley catheter. We examine obstetrical outcomes in women with Foley catheter placed after misoprostol compared with those only requiring misoprostol. STUDY DESIGN: Retrospective cohort study of singleton pregnancies, intact membranes, and an unfavorable cervix (Bishop score of ≤6 and dilation ≤2 cm) undergoing term induction May 2013 to June 2015. We compared obstetrical outcomes between women receiving misoprostol alone versus those that had a Foley catheter placed after misoprostol. Outcomes are mode of delivery, time to delivery, chorioamnionitis, admission to neonatal intensive care unit, and maternal morbidity. Chi-square and Fisher's exact tests were used for categorical variables, Mann-Whitney U-tests compared continuous variables. RESULTS: Among 364 women, 281 began induction with misoprostol alone. A total of 135 (48%) subsequently had a Foley catheter placed. Characteristics were similar between the groups, although nulliparity and cervical dilation <1 cm at start of induction were more likely to have subsequent Foley catheter. Women with Foley catheter placement after misoprostol had a longer median time to delivery (15 vs. 11 hours, p < 0.001), twofold higher rate of cesarean (42 vs. 26%, odds ratio: 2.1, 95% confidence interval: 1.26-3.44, p = 0.004), and increased risk of neonatal intensive care unit (NICU) admission (21 vs. 11%, p = 0.024). There was a nonsignificant increased risk of chorioamnionitis (12 vs. 7%, p = 0.1) and maternal morbidity (15 vs. 8%, p = 0.08) in the misoprostol followed by Foley catheter group. CONCLUSION: In women receiving misoprostol for induction, nulliparas and those with dilation <1 cm are more likely to have subsequent Foley catheter placement. Sequential use of cervical Foley catheter after misoprostol is associated with longer labor, higher cesarean rate, and increased NICU admission. Requirement of Foley catheter after misoprostol confers higher risk and may guide counseling. KEY POINTS: · Little is known regarding efficacy of misoprostol followed by cervical Foley catheter.. · Nulliparas and dilation <1 cm increases need for Foley after misoprostol.. · Complications were more common in women requiring Foley after misoprostol..
