Association of early postnatal transfer and birth outside a tertiary hospital with mortality and severe brain injury in extremely preterm infants: observational cohort study with propensity score matching.

OBJECTIVE: To determine if postnatal transfer or birth in a non-tertiary hospital is associated with adverse outcomes. DESIGN: Observational cohort study with propensity score matching. SETTING: National health service neonatal care in England; population data held in the National Neonatal Research Database. PARTICIPANTS: Extremely preterm infants born at less than 28 gestational weeks between 2008 and 2015 (n=17 577) grouped based on birth hospital and transfer within 48 hours of birth: upward transfer (non-tertiary to tertiary hospital, n=2158), non-tertiary care (born in non-tertiary hospital; not transferred, n=2668), and controls (born in tertiary hospital; not transferred, n=10 866). Infants were matched on propensity scores and predefined background variables to form subgroups with near identical distributions of confounders. Infants transferred between tertiary hospitals (horizontal transfer) were separately matched to controls in a 1:5 ratio. MAIN OUTCOME MEASURES: Death, severe brain injury, and survival without severe brain injury. RESULTS: 2181 infants, 727 from each group (upward transfer, non-tertiary care, and control) were well matched. Compared with controls, infants in the upward transfer group had no significant difference in the odds of death before discharge (odds ratio 1.22, 95% confidence interval 0.92 to 1.61) but significantly higher odds of severe brain injury (2.32, 1.78 to 3.06; number needed to treat (NNT) 8) and significantly lower odds of survival without severe brain injury (0.60, 0.47 to 0.76; NNT 9). Compared with controls, infants in the non-tertiary care group had significantly higher odds of death (1.34, 1.02 to 1.77; NNT 20) but no significant difference in the odds of severe brain injury (0.95, 0.70 to 1.30) or survival without severe brain injury (0.82, 0.64 to 1.05). Compared with infants in the upward transfer group, infants in the non-tertiary care group had no significant difference in death before discharge (1.10, 0.84 to 1.44) but significantly lower odds of severe brain injury (0.41, 0.31 to 0.53; NNT 8) and significantly higher odds of survival without severe brain injury (1.37, 1.09 to 1.73; NNT 14). No significant differences were found in outcomes between the horizontal transfer group (n=305) and controls (n=1525). CONCLUSIONS: In extremely preterm infants, birth in a non-tertiary hospital and transfer within 48 hours are associated with poor outcomes when compared with birth in a tertiary setting. We recommend perinatal services promote pathways that facilitate delivery of extremely preterm infants in tertiary hospitals in preference to postnatal transfer.

How singleton breech babies at term are born in France: a survey of data from the AUDIPOG network.

Based on data from the AUDIPOG sentinel network between 1994 and 2010, we can say that the rate of singleton breech presentation at term is 3% and remains unchanged despite an external cephalic version rate of 35%. The total cesarean section rate is currently 75%. This rate increased by nearly 20% after the Hannah publication in 2000, regardless of the type of breech and type of maternity unit. The rate of planned cesarean sections increased in particular, going from 40% to 60%, and even reaching 67% for footling breech presentations. The rate is higher in type I maternity units than in type II or III. This cesarean section rate has been stable since 2005 and has even decreased for the Frank breech. The average rate of external cephalic version remains stable at around 23%. The episiotomy rate is 28%. The rate of babies transferred to neonatology units is higher for breech babies at term than for babies presenting cephalically (3.9% compared to 2.9%), but the newborns most often transferred are those born by cesarean section (4.1% compared to 3.4%).

Characteristics, interventions, and outcomes of women who used a birthing pool: a prospective observational study.

BACKGROUND: Birthing pools are integrated into maternity care in the United Kingdom and are a popular care option for women in midwifery-led units and at home. The objective of this study was to describe and compare maternal characteristics, intrapartum events, interventions, and maternal and neonatal outcomes by planned place of birth for women who used a birthing pool. METHODS: A total of 8,924 women at low risk of childbirth complications were recruited from care settings in England, Scotland, and Northern Ireland. Descriptive analysis was performed. RESULTS: Overall, 7,915 (88.9%) women had a spontaneous birth (5,192, 58.3% water births), of whom 4,953 (55.5%) were nulliparas. Fewer nulliparas whose planned place of birth was the community (freestanding midwifery unit or home) had labor augmentation by artificial membrane rupture (149, 11.3% [95% CI: 9.6-13.1]), compared with an alongside midwifery unit (271, 22.7% [95% CI: 20.3-25.2]), or obstetric unit (639, 26.3% [95% CI: 24.5-28.1]). Results were similar for epidural analgesia and episiotomy. More community nulliparas had spontaneous birth (1,172, 88.9% [95% CI: 87.1-90.6]), compared with birth in an alongside midwifery unit (942, 79% [95% CI: 76.6-81.3]) and obstetric unit (1,923, 79.2% [95% CI: 77.5-80.8]); and fewer required hospital transfer (265, 20% [95% CI: 17-22.2]) compared with those in an alongside midwifery unit (370, 31% [95% CI: 28.3-33.7]). Results for multiparas and newborns were similar across care settings. Twenty babies had an umbilical cord snap, 18 (90%) of which occurred during water birth. CONCLUSIONS: Birthing pool use was associated with a high frequency of spontaneous birth, particularly among nulliparas. Findings revealed differences in midwifery practice between obstetric units, alongside midwifery units, and the community, which may affect outcomes, particularly for nulliparas. No evidence was found for a difference across care settings in interventions or outcomes in multiparas or in outcomes for newborns. During water birth, it is important to prevent undue traction on the cord as the baby is guided to the surface.

Case-mix adjusted odds ratios as an alternative way to compare hospital performances.

The purpose of this study was to compare two different methods to describe C-section variability among hospital units: case-mix adjusted ORs and case-mix adjusted rates. About 41,755 deliveries without previous C-section occurred in 60 hospitals in 2001 were analysed. Logistic regression was used to produce both adjusted rates and ORs by maternity unit. The two methods showed similar rankings, however ORs estimates were more precise and proved to be a useful tool to describe C-section variability across hospitals.

Utilidad de la evaluación de 10 grupos clínicos obstétricos para la reducción de la tasa de cesárea en un hospital docente / Utility of the evaluation of 10 clinical obstetric groups for the reduction of the cesarean sections rate in an educational hospital

La tasa de cesárea es uno de los indicadores que evalúa la calidad de la atención perinatal. En Chile, su sostenida alza ha sido motivo de permanente debate. Se realizó un estudio observacional retrospectivo clasificando la población obstétrica en 10 grupos clínicos con el objeto de pesquisar aquellos en donde intervenciones clínicas sean potencialmente relevantes para disminuir la tasa de cesárea. Se compararon los resultados perinatales de dos años consecutivos durante los cuales la tasa de cesárea aumentó de 23,9 por ciento a 30 por ciento. Las pacientes con cicatriz de cesárea constituyeron el grupo de mayor contribución a la tasa de cesárea; sin embargo, las nulíparas con gestación de término única en presentación cefálica y trabajo de parto espontáneo, representaron el mayor aumento en la tasa de cesárea. La evaluación de las indicaciones de cesárea en este último grupo deja abierta la posibilidad de disminuir la tasa de cesárea con intervenciones clínicas específicas.

Differential markers for regionalization.

OBJECTIVE: To examine the site of delivery for very low birth weight (VLBW) infants and infants with major congenital malformations (MCM) within an established system of perinatal regionalization. STUDY DESIGN: A retrospective study of site of delivery for VLBW infants and infants born with MCM (tracheoesophageal fistula/esophageal atresia, diaphragmatic hernia, or gastroschisis/omphalocele) from 1990 through 1995 in Ohio. RESULTS: A total of 59.8% of VLBW infants and 36.1% of MCM infants were born in a level III hospital. There was a significant trend toward a decrease in VLBW infants (p < 0.01) and an increase in MCM infants (p < 0.05) born in a level III hospital between 1990 and 1995. There were significant regional variations among the six perinatal regions in Ohio in the proportion of both VLBW and MCM infants born in a tertiary center. CONCLUSION: Using the traditional marker of VLBW to assess regionalization in one state, we found significant variation in site of delivery among the perinatal regions and over the time course of the study. The delivery of infants with MCM at level III centers may be an alternative measure of regionalization.

Use of high-technology care among women with high-risk pregnancies in the United States.

OBJECTIVE: Infant mortality has been reduced dramatically with the development of perinatal regionalized high-technology care. Our objective was to assess use of high technology care among women with high-risk pregnancies in the urban and rural United States. METHODS: The 1988 National Maternal and Infant Health Survey was linked to the 1988 American Hospital Association survey of all obstetrical hospitals. Hospitals were classified into five levels of care based on services and staffing. Women were classified as having high-risk pregnancies using two definitions: (1) gestational age < 34 weeks and birthweight < 1500 g (High Risk I) and (2) the first definition or an antenatal high-risk medical diagnoses (High Risk II). Analyses assessed the proportion of high-risk women delivering in appropriate locations in the rural and urban United States and explored how personal characteristics, insurance status, and use and source of prenatal care influenced where high-risk women delivered. RESULTS: 71.2% of High Risk I and 55.9% of High Risk II women delivered in a high-technology facility (Level IIA or III). Fifty percent of HRI rural women delivered in tertiary high-technology hospitals and 39% of HRII rural women delivered in a high-technology hospital. High-risk urban women were two to three times more likely to deliver in a high-technology facility compared to their rural counterparts. The multivariate analysis showed that Black high-risk women were more likely to deliver in a high-technology setting and that receipt of prenatal care in a private setting lowered the odds of delivering in a high-technology setting when other factors were controlled. CONCLUSIONS: In an era where regionalized perinatal care was not threatened by managed care, a large proportion of high-risk women received care in less than optimal settings. Rural high-risk women delivered in high-technology hospitals less often than their urban counterparts. The multivariate analyses implied that the potential barriers to care may be more important among those considered more socially advantaged, who may be more at the mercy of managed care. The current reimbursement environment, which discourages referral to specialists and high-technology care, could result in less access today.

Cesarean section rates by type of maternity unit and level of obstetric care: an area-based study in central Italy.

BACKGROUND: The rate of cesarean section in the Lazio region of Italy is one of the highest in the Western world, 26.5%. In order to evaluate the effects of nonmedical factors on cesarean section, we examined its relationship to the characteristics of maternity units in the region. METHODS: We collected data from the birth certificates of 91,557 infants born to women residing in Lazio in 1988-1989 and classified all maternity units in the region by method of financing (public, semiprivate with arrangements with the national health service, and completely private) and level of obstetric care (unclassified and levels I,II, and III). The rates of cesarean section were examined for primiparous and multiparous women, taking into account birthweight, gestational age, fetal presentation, maternal age, and day of delivery. RESULTS: The adjusted odds ratio for cesarean section (with public units of level I taken as reference) was 1.06 (primiparous) and 1.22 (multiparous) for semiprivate maternity units and 1.59 (primiparous) and 1.52 (multiparous) for private units; it increased to 1.59 (primiparous) and 1.61 (multiparous) for unclassified semiprivate units and to 2.06 (primiparous) and 1.87 (multiparous) for unclassified private units. CONCLUSIONS: The rate of cesarean section was associated in the Lazio region with private payment for hospital care and with inadequate level of obstetric care. The latter factor is of particular concern and should be investigated elsewhere.
