Severe adverse maternal and neonatal outcomes according to the planned birth setting being midwife-led birth centers or obstetric-led units.

INTRODUCTION: The establishment of midwife-led birth centers (MLBCs) is still being debated. The study aimed to compare severe adverse outcomes and mode of birth in low-risk women according to their birth planned in MLBCs or in obstetric-led units (OUs) in France. MATERIAL AND METHODS: We used nationwide databases to select low-risk women at the start of care in labor in MLBCs (n = 1294) and in OUs (n = 5985). Using multilevel logistic regression, we compared severe adverse maternal and neonatal morbidity as a composite outcome and as individual outcomes. These include severe postpartum hemorrhage (≥1000 mL of blood loss), obstetrical anal sphincter injury, maternal admission to an intensive care unit, maternal death, a 5-minute Apgar score <7, neonatal resuscitation at birth, neonatal admission to an intensive care unit, and stillbirth or neonatal death. We also studied the mode of birth and the role of prophylactic administration of oxytocin at birth in the association between birth settings and severe postpartum hemorrhage. RESULTS: Severe adverse maternal and neonatal outcome indicated a slightly higher rate in women in MLBCs compared to OUs according to unadjusted analyses (4.6% in MLBCs vs. 3.4% in OUs; cOR 1.36; 95%CI [1.01-1.83]), but the difference was not significant between birth settings after adjustment (aOR 1.37 [0.92-2.05]). Severe neonatal morbidity alone was not different (1.7% vs. 1.6%; aOR 1.17 [0.55-2.47]). However, severe maternal morbidity was significantly higher in MLBCs than in OUs (3.0% vs. 1.9%; aOR 1.61 [1.09-2.39]), mainly explained by higher risks of severe postpartum hemorrhage (2.4 vs. 1.1%; aOR 2.37 [1.29-4.36]), with 2 out of 5 in MLBCs partly explained by the low use of prophylactic oxytocin. Cesarean and operative vaginal births were significantly decreased in women with a birth planned in MLBCs. CONCLUSIONS: In France, 3 to 4% of low-risk women experienced a severe adverse maternal or neonatal outcome regardless of the planned birth setting. Results were favorable for MLBCs in terms of mode of birth but not for severe postpartum hemorrhage, which could be partly addressed by revising practices of prophylactic administration of oxytocin.

Preferences for labor and childbirth, expressed orally or as a written birth plan: Prevalence and determinants from a nationwide population-based study.

BACKGROUND: Shared decision-making is an important component of a patient-centered healthcare system. We assessed the prevalence of parturients with preferences for their labor and childbirth, expressed verbally in the birthing room or as a written birth plan, and studied maternal, obstetric, and organizational factors associated with their expression. METHODS: Data came from the 2016 National Perinatal Survey, a cross-sectional nationwide population-based survey conducted in France. Preferences for labor and childbirth were studied in three categories: expressed verbally, in writing (birth plan), or unexpressed or nonexistent. Analyses used multinomial multilevel logistic regression. RESULTS: The analysis included 11,633 parturients: 3.7% had written a birth plan, 17.3% expressed their preferences verbally, and 79.0% either did not have or did not express any preferences. Compared with the latter group, written or verbal preferences were both significantly associated with prenatal care by independent midwives (respectively, adjusted odds ratio (aOR) 2.19; 95% confidence interval (CI), [1.59-3.03], and aOR 1.43; 95% CI [1.19-1.71]) and with attendance at childbirth education classes (respectively, aOR 4.99; 95% CI [3.49-7.15], and aOR 2.27; 95% CI [1.98-2.62]). As years in traditional schooling increased, so did its association with preferences. Conversely, parturients from African countries were significantly less likely than French mothers to express preferences. A written birth plan was also associated with characteristics of maternity unit organization. CONCLUSION: Only one in five parturients reported having expressed preferences for labor and childbirth to healthcare professionals in the birthing room. This expression of preferences was associated with maternal characteristics and the organization of care.

Alternative to intensive management of the active phase of the second stage of labor: a multicenter randomized trial (Phase Active du Second STade trial) among nulliparous women with an epidural.

BACKGROUND: There is no consensus on an optimal strategy for managing the active phase of the second stage of labor. Intensive pushing could not only reduce pushing duration, but also increase abnormal fetal heart rate because of cord compression and reduced placental perfusion and oxygenation resulting from the combination of uterine contractions and maternal expulsive forces. Therefore, it may increase the risk of neonatal acidosis and the need for operative vaginal delivery. OBJECTIVE: This study aimed to assess the effect of the management encouraging "moderate" pushing vs "intensive" pushing on neonatal morbidity. STUDY DESIGN: This study was a multicenter randomized controlled trial, including nulliparas in the second stage of labor with an epidural and a singleton cephalic fetus at term and with a normal fetal heart rate. Of note, 2 groups were defined: (1) the moderate pushing group, in which women had no time limit on pushing, pushed only twice during each contraction, and observed regular periods without pushing, and (2) the intensive pushing group, in which women pushed 3 times during each contraction and the midwife called an obstetrician after 30 minutes of pushing to discuss operative delivery (standard care). The primary outcome was a composite neonatal morbidity criterion, including umbilical arterial pH of <7.15, base excess of >10 mmol/L, lactate levels of >6 mmol/L, 5-minute Apgar score of <7, and severe neonatal trauma. The secondary outcomes were mode of delivery, episiotomy, obstetrical anal sphincter injuries, postpartum hemorrhage, and maternal satisfaction. RESULTS: The study included 1710 nulliparous women. The neonatal morbidity rate was 18.9% in the moderate pushing group and 20.6% in the intensive pushing group (P=.38). Pushing duration was longer in the moderate group than in the intensive group (38.8±26.4 vs 28.6±17.0 minutes; P<.001), and its rate of operative delivery was 21.1% in the moderate group compared with 24.8% in the intensive group (P=.08). The episiotomy rate was significantly lower in the moderate pushing group than in the intensive pushing group (13.5% vs 17.8%; P=.02). We found no significant difference for obstetrical anal sphincter injuries, postpartum hemorrhage, or maternal satisfaction. CONCLUSION: Moderate pushing has no effect on neonatal morbidity, but it may nonetheless have benefits, as it was associated with a lower episiotomy rate.

Maternal Intensive Care Unit Admission as an Indicator of Severe Acute Maternal Morbidity: A Population-Based Study.

BACKGROUND: Severe acute maternal morbidity (SAMM) accounts for any life-threatening complication during pregnancy or after delivery. Measuring and monitoring SAMM seem critical to assessing the quality of maternal health care. The objectives were to explore the validity of intensive care unit (ICU) admission as an indicator of SAMM by characterizing the profile of women admitted to an ICU and of their ICU stay, according to the association with other SAMM criterion. METHODS: We performed a secondary analysis of the 2540 women with SAMM included in the epidemiology of severe acute maternal morbidity (EPIMOMS) multiregional prospective population-based study (2012-2013, n = 182,309 deliveries). The EPIMOMS definition of SAMM, based on national experts' consensus, is a combination of diagnosis, organ dysfunctions, and intervention criteria, including ICU admission. Among women with SAMM, we identified characteristics associated with maternal ICU admission with or with no other SAMM criterion compared with ICU admission, by using multivariable multinomial logistic regression models. RESULTS: Overall, 511 women were admitted to an ICU during or up to 42 days after pregnancy, for a population-based rate of 2.8 of 1000 deliveries (511/182,309; 95% confidence interval [CI], 2.6-3.1); 15.5% of them (79/511; 95% CI, 12.4-18.9) had no other SAMM criterion compared with ICU admission. Among women with SAMM, the odds of ICU admission with no other morbidity criterion were increased in women with preexisting medical conditions (adjusted odds ratio (aOR), 2.13; 95% CI, 1.17-3.86) and cesarean before labor (aOR, 3.12; 95% CI, 1.47-6.64). Women admitted to ICU with no other SAMM criterion had more often decompensation of a preexisting condition, no interventions for organ support, and a shorter length of stay than women admitted with other SAMM criteria. CONCLUSIONS: Among women with SAMM, 1 in 5 is admitted to an ICU; 15.5% of those admitted in ICU have no other SAMM criterion and a less acute condition. These results challenge the use of ICU admission as a criterion of SAMM.

Pregnancy-related ICU admissions in France: trends in rate and severity, 2006-2009.

OBJECTIVE: To determine the national rate per delivery of pregnancy-related ICU admissions of women in France, the characteristics and severity of these cases, and their trends over the 4-year study period. DESIGN: Descriptive study from the national hospital discharge database. SETTING: All ICUs in France. PATIENTS: All women admitted to an ICU during the pregnancy, the delivery, or the postpartum period from January 1, 2006, to December 31, 2009. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Of 3,262,526 deliveries, 11,824 women had pregnancy-related ICU admissions, for an overall rate of 3.6 per 1,000 deliveries. The conditions reported most frequently were obstetric hemorrhages (34.2%) and hypertensive disorders of pregnancy (22.3%). Case severity was assessed with four markers: case-fatality rate (1.3%), length of ICU stay (mean, 3.0 ± 0.1 d), Simplified Acute Physiology Score II score (mean: 19.7 ± 0.1), and a SUP REA code, which indicates the combination of a Simplified Acute Physiology Score II score more than or equal to 15 and at least one specific procedure related to life support or organ failure (23.0%). The most frequent causes of ICU admission were those associated with the least severity in the ICU. During the study period, the rate of pregnancy-related ICU admissions decreased from 3.9 to 3.4 per 1,000 deliveries (p < 0.001), whereas the overall severity of cases increased with longer stays, higher Simplified Acute Physiology Score II scores, and a greater proportion of SUP REA codes (all p < 0.001). Analysis by principal diagnosis showed that the severity of the condition of women admitted to ICU significantly increased over time for hemorrhages and hypertensive complications. CONCLUSIONS: The rate of women with pregnancy-related ICU admissions decreased and the severity of their cases increased. Most ICU admissions remained related to the least severe conditions. This raises the issue of the most appropriate organization of care for women with pregnancy-related conditions who require continuous surveillance but not necessarily intensive care.

Consent for interventions during childbirth: A national population-based study.

OBJECTIVE: To assess the frequency and determinants of medical interventions during childbirth without women's consent at the population level. METHODS: The nationwide cross-sectional Enquête Nationale Périnatale 2021 provided a representative sample of women who delivered in metropolitan France with a 2-month postpartum follow-up (n = 7394). Rates and 95% confidence intervals (CI) of interventions during childbirth (oxytocin administration, episiotomy or emergency cesarean section) without consent were calculated. Associations with maternal, obstetric, and organizational characteristics were assessed using robust variance Poisson regressions, after multiple imputation for missing covariates, and weighted to account for 2-month attrition. RESULTS: Women reporting failure to seek consent were 44.7% (CI: 42.6-47.0) for oxytocin administration, 60.2% (CI: 55.4-65.0) for episiotomy, and 36.6% (CI: 33.3-40.0) for emergency cesarean birth. Lack of consent for oxytocin was associated with maternal birth abroad (adjusted prevalence ratio [aPR] 1.20; 95% CI: 1.06-1.36), low education level, and increased cervical dilation at oxytocin initiation, whereas women with a birth plan reported less frequently lack of consent (aPR 0.79; 95% CI: 0.68-0.92). Delivery assisted by an obstetrician was more often associated with lack of consent for episiotomy (aPR 1.46; 95% CI: 1.11-1.94 for spontaneous delivery and aPR 1.39; 95% CI: 1.13-1.72 for instrumental delivery, reference: spontaneous delivery with a midwife). Cesarean for fetal distress was associated with failure to ask for consent for emergency cesarean delivery (aPR 1.58; 95% CI: 1.28-1.96). CONCLUSION: Women frequently reported that perinatal professionals failed to seek consent for interventions during childbirth. Reorganization of care, particularly in emergency contexts, training focusing on adequate communication and promotion of birth plans are necessary to improve women's involvement in decision making during childbirth.

Repeated maternal ICU admission: Results from a nationwide analysis.

OBJECTIVE: To determine the rate and profile of repeated maternal ICU admissions during or after pregnancy and to compare the characteristics of these women's first and second ICU admissions. METHODS: A descriptive analysis from the French national hospital discharge database that included all women admitted to an ICU during pregnancy or within 42 days after delivery, between 2010 and 2014. RESULTS: During the 5-year study period, there were 371 women with more than one maternal ICU admission, representing 2.5% of all women admitted during or after pregnancy (371/15,096) and a 0.9 per 10,000 deliveries (371/4,030,409) rate of repeated maternal ICU admission. Compared with women with only one maternal ICU admission, those with repeated maternal ICU admissions were more often admitted during the pregnancy rather than during or after the delivery stay (P < 0.001), for organ failure or sepsis (P < 0.001), and with a SAPS-II score > 25 (P < 0.001). Women with repeated admissions were usually readmitted for the same indications and had similar SAPS-II scores. Half of ICU readmissions occurred within 72 h of first ICU discharge, with similar causes and levels of severity for both stays. CONCLUSION: Although the rate of women with repeated maternal ICU admissions was low, their initial stay had a specific profile of causes of admission and greater severity compared with the stay of women admitted only once. The pattern and similar characteristics of both first and second ICU admission and the short interval for readmission suggests that some ICU discharges may have been potentially premature.

Monitoring quality of obstetric care from hospital discharge databases: A Delphi survey to propose a new set of indicators based on maternal health outcomes.

OBJECTIVES: Most indicators proposed for assessing quality of care in obstetrics are process indicators and do not directly measure health effects, and cannot always be identified from routinely available databases. Our objective was to propose a set of indicators to assess the quality of hospital obstetric care from maternal morbidity outcomes identifiable in permanent hospital discharge databases. METHODS: Various maternal morbidity outcomes potentially reflecting quality of obstetric care were first selected from a systematic literature review. Then a three-round Delphi consensus survey was conducted online from 11/2016 through 02/2017 among a French panel of 37 expert obstetricians, anesthetists-critical-care specialists, midwives, quality-of-care researchers, and user representatives. For a given maternal outcome, several definitions could be proposed and the indicator (i.e. corresponding rate) could be applied to all women or restricted to specific subgroup(s). RESULTS: Of the 49 experts invited to participate, 37 agreed. The response rate was 92% in the second round and 97% in the third. Finally, a set of 13 indicators was selected to assess the quality of hospital obstetric care: rates of uterine rupture, postpartum hemorrhage, transfusion incident, severe perineal lacerations, episiotomy, cesarean, cesarean under general anesthesia, post-cesarean site infection, anesthesia-related complications, postpartum pulmonary embolism, maternal readmission and maternal mortality. Six were considered in specific subgroups, with, for example, the postpartum hemorrhage rate assessed among all women and also among women at low risk of PPH. IMPLICATIONS: This Delphi process enabled us to define consensually a set of indicators to assess the quality of hospital obstetrics care from routine hospital data, based on maternal morbidity outcomes. Considering 6 of them in specific subgroups of women is especially interesting. These indicators, identifiable through codes used in international classifications, will be useful to monitor quality of care over time and across settings.
