Validation of a measure of hospital maternal level of care for the United States.

BACKGROUND: Lack of a validated assessment of maternal risk-appropriate care for use in population data has prevented the existing literature from quantifying the benefit of maternal risk-appropriate care. The objective of this study was to develop a measure of hospital maternal levels of care based on the resources available at the hospital, using existing data available to researchers. METHODS: This was a secondary data analysis. The sample was abstracted from the American Hospital Association Annual Survey Database for 2018. Eligibility was limited to short-term acute general hospitals that reported providing maternity services as measured by hospital reporting of an obstetric service level, obstetric services, or birthing rooms. We aligned variables in the database with the ACOG criteria for each maternal level of care, then built models that used the variables to measure the maternal level of care. In each iteration, the distribution of hospitals was compared to the distribution in the CDC Levels of Care Assessment Tool Validation Pilot, assessing agreement with the Wilson Score for proportions for each level of care. Results were compared to hospital self-report in the database and measurement reported with another published method. RESULTS: The sample included 2,351 hospitals. AHA variables were available to measure resources that align with ACOG Levels 1, 2, and 3. Overall, 1219 (51.9%) of hospitals reported resources aligned with Maternal Level One, 816 (34.7%) aligned with maternal level two, and 202 (8.6%) aligned with maternal level Three. This method overestimates the prevalence of hospitals with maternal level one compared to the CDC measurement of 36.1% (Mean 52.9%; 95% CI47.2%-58.7%), and likely includes hospitals that would not qualify as level one if all resources required by the ACOG guidelines could be assessed. This method underestimates the prevalence of hospitals with maternal critical care services (Level 3 or 4) compared to CDC measure of 12.1% (Mean 8.1%; 95%CI 6.2% - 10.0%) but is an improvement over hospital self-report (24.7%) and a prior published method (32.3%). CONCLUSIONS: This method of measuring maternal level of care allows researchers to investigate the value of perinatal regionalization, risk-appropriate care, and hospital differences among the three levels of care. This study identified potential changes to the American Hospital Association Annual Survey that would improve identification of maternal levels of care for research.

Associations Between State Practice Regulations and Access to Midwifery Care.

INTRODUCTION: This study aimed to identify associations between state policies and access to midwifery care. Identifying policies that facilitate increased access to midwives will help policymakers determine the best methods for increasing access to midwives in their states. METHODS: This cross-sectional study was conducted at the county level as a secondary analysis of National Vital Statistics data from the Natality online database. The unit of analysis was counties with populations of at least 100,000, and the outcome was the proportion of births attended by midwives in 2019. The potential predictors of increased access to midwifery care were independent midwife licensure, independent midwife prescribing, midwife access to hospital medical staff membership, and midwife Medicaid parity. Medicaid provider resources and state statutes verified Medicaid reimbursement rates and eligibility for hospital medical staff privileges. Each state was categorized as an independent or restricted licensure state according to data from the American College of Nurse-Midwives. Data for the control variable, the presence of a midwifery education program, were gathered from the Accreditation Commission for Midwifery Education. The analysis was conducted as a Poisson regression. RESULTS: There was no association between independent licensing and increased access among all states. Stratifying the analysis by independent licensing law revealed that all but one policy was related to higher rates of midwife attendance at birth. Maximum Medicaid reimbursement correlated with greater access regardless of licensing status. The rate of midwife-attended births in independent licensing states grew as the number of potential predictors in a county increased. DISCUSSION: Regulatory policies beyond independent licensing are associated with women's access to midwifery services. In independent licensing states, adopting additional policies favorable to midwives may strengthen access to midwifery. Policymakers and regulators can use these findings to identify strategies for accelerating the expansion of midwifery access in their states.

Evaluation of a method to identify midwives in national provider identifier data.

OBJECTIVES: Comparison of national midwife workforce data from the National Provider Identifier file determined it undercounted midwives compared to national data available from the American Midwifery Certification Board. This undercount may be due to the existence of three taxonomy categories for midwives when registering for the National Provider Identifier. The objective of this study was to obtain an accurate count of advanced practice midwives using the National Provider Identifier Data. METHODS: A recode strategy was created using the NPPES Data Dissemination File for November 7, 2021. The strategy identified advanced practice midwives using education and certification information provided in the "credentials" field. The strategy was validated using the NPPES Data Dissemination File for August 7, 2022 and the gold standard was the American Midwifery Certification Board count of midwives by state for August, 2022. Validation compared the accuracy and precision of the recode to the accuracy and precision of using the advanced practice midwife taxonomy category. RESULTS: The recode strategy improved the accuracy and precision of the count of advanced practice midwives compared to the identification of advanced practice midwives using the advanced practice midwife taxonomy category. CONCLUSIONS FOR PRACTICE: Recoding the NPPES Data Dissemination File provides a more accurate and precise count of advanced practice midwives than relying on the existing advanced practice midwife taxonomy classification. Researchers can use the NPPES Data Dissemination File when studying the midwifery workforce.

Outcomes of Childbirth Education for Women With Pregnancy Complications.

The purpose of this study was to examine associations between pregnancy outcomes and childbirth education, identifying any outcomes moderated by pregnancy complications. This was a secondary analysis of the Pregnancy Risk Assessment Monitoring System, Phase 8 data for four states. Logistic regression models compared outcomes with childbirth education for three subgroups: women with no pregnancy complications, women with gestational diabetes, and women with gestational hypertension. Women with pregnancy complications do not receive the same benefit from attending childbirth education as women with no pregnancy complications. Women with gestational diabetes who attended childbirth education were more likely to have a cesarean birth. The childbirth education curriculum may need to be altered to provide maximum benefits for women with pregnancy complications.

American Midwifery Certification Board Certification Demographic and Employment Data, 2016 to 2020: The Certified Nurse-Midwife and Certified Midwife Workforce.

INTRODUCTION: Expansion and diversification of the midwifery workforce is a federal strategy to address the maternal health crisis in the United States. Understanding characteristics of the current midwifery workforce is essential to creating approaches to its development. Certified nurse-midwives and certified midwives (CNMs/CMs) certified by the American Midwifery Certification Board (AMCB) constitute the largest portion of the US midwifery workforce. This article aims to describe the current midwifery workforce based on data collected from all AMCB-certified midwives at the time of certification. METHODS: Midwife initial certificants and recertificants were administered an electronic survey about personal and practice characteristics at the time of certification by AMCB between 2016 and 2020 for administrative purposes. Given the standard 5-year certification cycle, every midwife certified during this period completed the survey once. The AMCB Research Committee conducted a secondary data analysis of deidentified data to describe the CNM/CM workforce. RESULTS: In 2020 there were 12,997 CNMs/CMs in the United States. The workforce was largely White and female with an average age of 49. There has been a slow increase (15% to 21%) of initial certificants identifying as midwives of color. The proportion of CMs to all AMCB-certified midwives remained less than 2%. Physician-owned practices were the most common employer. Approximately 60% of midwives attend births, and hospitals were the most common birth setting. Over 10% of those certified to practice reported not working within the discipline of midwifery. DISCUSSION: Targeted recruitment and retention of midwives must take into consideration not just expansion but dispersion, scope of practice, and diversification. The proportion of midwives attending births was lower than reported in previous years. Expansion of the CM credential and accessible educational pathways are 2 potential solutions to workforce growth. Developing strategies to retain those who are trained but not practicing presents an opportunity for workforce maintenance.

Content Analysis of Water Birth Policies With Implications for Practice and Research.

OBJECTIVE: To identify areas of agreement and variation in clinical guidance documents (protocols, policies, or guidelines) that direct water birth care. DESIGN: Qualitative descriptive. SETTING: The clinical guidance documents studied covered water birth in home and hospital settings. SAMPLE: The sample included 22 water birth guidance documents in English from six countries. The documents were obtained by request and resulting snowball sampling. MEASUREMENTS: The framework method was adapted as an analytic tool, and a structured matrix output was used to organize and support the method of qualitative content analysis using a general inductive approach. Areas of general agreement and variations in practice guidelines for water birth were identified. RESULTS: Criteria for a term, singleton, and cephalic presentation with reassuring maternal and fetal status were the most consistent for inclusion. The reliance on "low-risk" status was strongly present but without a uniform definition. A history of previous cesarean birth, body mass index, use of opioid pain medication, adequate labor progress, and vaginal bleeding were found to vary in directed care, and scarce supporting evidence was offered. Meconium-stained fluid variably excluded water birth in most documents, but this was not supported by evidence. The inconsistent findings from this study are cohesive in the evidence they provide for needed research in areas that affect access to water birth. The findings also provide nurses and birth providers with evidence-based guidelines for water birth care. CONCLUSION: There was variation across guidance documents, demonstrating that water immersion is a flexible intervention that can be implemented in different settings and locations while following individual facility protocols for processes for care. An identified area of concern comes from examples of overly restrictive policies for water birth based on opinion or perceived risk rather than evidence from research.

Midwifery Workforce Density Moderates the Association Between Independent Practice and Pregnancy Outcomes.

INTRODUCTION: Studies comparing pregnancy outcomes before and after state transition to independent midwifery practice have found little change in primary cesarean birth and preterm birth rates. One reason may be the failure to control for midwife density. The objective was to test if the local midwife density moderates the association between state independent midwifery practice and pregnancy outcomes. METHODS: Birth records were abstracted from the State Inpatient Databases for 6 states. The Area Health Resource File provided county variables. Midwife density was operationalized as no midwives, low midwife density (<4.5 per 1000 births), and high midwife density (≥4.5 midwives per 1000 births). Multivariate logistic regression models compared primary cesarean birth and preterm birth, controlling for maternal and county characteristics. Moderation was tested by including an interaction term (independent practice × density) to the regression models. The magnitude of association for the interaction was measured by stratifying the models. RESULTS: The study included 875,156 women; most (79.7%) resided in a county with low midwife density. Restricted midwifery practice was associated with increased odds of both primary cesarean birth and preterm birth. The interaction term was significant for both preterm birth and primary cesarean, indicating moderation. The largest magnitude of difference was the increased odds of preterm birth in counties with a high midwife density and restricted practice (odds ratio, 3.50; 95% CI, 2.43-5.06) compared with those with high midwife density and independent practice. DISCUSSION: Midwife density moderates the association between independent midwifery practice and primary cesarean birth and preterm birth. Moderation may explain why prior studies found small or no changes in outcomes when states adopted independent practice. Moderation models can improve testing for associations with independent practice. Both midwife independent practice and increasing midwifery workforce size can be strategies to improve state pregnancy outcomes.

Timing of hospital admission at first childbirth: A prospective cohort study.

BACKGROUND AND AIMS: It is difficult for women in labor to determine when best to present for hospital admission, particularly at first childbirth. While it is often recommended that women labor at home until their contractions have become regular and ≤ 5-minutes apart, little research has investigated the utility of this recommendation. This study investigated the relationship between timing of hospital admission, in terms of whether women's labor contractions had become regular and ≤ 5-minutes apart before admission, and labor progress. METHODS: This was a cohort study of 1,656 primiparous women aged 18-35 years with singleton pregnancies who began labor spontaneously at home and delivered at 52 hospitals in Pennsylvania, USA. Women who were admitted before their contractions had become regular and ≤ 5-minutes apart (early admits) were compared to those who were admitted after (later admits). Multivariable logistic regression models were used to assess associations between timing of hospital admission and active labor status on admission (cervical dilation 6-10 cm), oxytocin augmentation, epidural analgesia and cesarean birth. RESULTS: Nearly two-thirds of the participants (65.3%) were later admits. These women had labored for a longer time period before admission (median, interquartile range [IQR] 5 hours (3-12 hours)) than the early admits (median, (IQR) 2 hours (1-8 hours), p < 0.001); were more likely to be in active labor on admission (adjusted OR [aOR] 3.78, 95% CI 2.47-5.81); and were less likely to experience labor augmentation with oxytocin (aOR 0.44, 95% CI 0.35-0.55); epidural analgesia (aOR 0.52, 95% CI 0.38-0.72); and cesarean birth (aOR 0.66, 95% CI 0.50-0.88). CONCLUSIONS: Among primiparous women, those who labor at home until their contractions have become regular and ≤ 5-minutes apart are more likely to be in active labor on hospital admission and less likely to experience oxytocin augmentation, epidural analgesia and cesarean birth.

Outcomes of Childbirth Education in PRAMS, Phase 8.

OBJECTIVE: To determine if childbirth education is associated with improved outcomes for national maternal child health goals in the United States. METHODS: This was a secondary analysis of PRAMS data. The sample was limited to survey respondents who answered a question "During your most recent pregnancy, did you take a class or classes to prepare for childbirth and learn what to expect during labor and delivery?" The outcomes included nine national objectives from Title V and Healthy People. Logistic regression models were built with control for characteristics associated with attending childbirth education. Odds ratios were converted to adjusted risk ratios for interpretation. Stratification by maternal race/ethnicity and use of Medicaid identified opportunities for improvement in childbirth education. RESULTS: Of the 2,256 eligible respondents, 936 (41.5%) attended childbirth education. Attending childbirth education was associated with reduced likelihood of primary cesarean (ARR 0.79), increased attendance at postpartum visit (ARR 1.06), use of birth control (ARR 1.07), safe infant sleep (Back to Sleep ARR 1.04; Sleep on Own 1.12), and breastfeeding (Ever breastfeed ARR 1.08; still breastfeeding ARR 1.15). No association was found for LARC use or postpartum depression. Not all benefits of childbirth education were apparent for all racial/ethnic groups, nor for those with Medicaid insurance. CONCLUSIONS FOR PRACTICE: Childbirth education is a community intervention that may help achieve population maternal and child health goals.

Midwifery Autonomy and Employment Changes During the Early COVID-19 Pandemic.

INTRODUCTION: The COVID-19 pandemic presented the midwifery workforce with challenges for maintaining access to high-quality care and safety for patients and perinatal care providers. This study analyzed associations between different types of professional autonomy and changes in midwives' employment and compensation during the early months of the pandemic. METHODS: An online survey distributed to midwifery practices in fall 2020 compared midwives' employment and compensation in February 2020 and September 2020. Chi-square analysis determined associations between those data and measures of midwives' autonomy: state practice environment, midwifery practice ownership, intrapartum practice setting, and midwifery participation in practice decision-making. RESULTS: Participants included lead midwives from 727 practices, representing 50 states and the District of Columbia. Full-time equivalent (FTE) positions and number of full-time midwives were stable for 77% of practices, part-time employment for 83%, and salaries for 72%. Of the remaining practices, more practices lost FTE positions, full-time positions, part-time positions, and salary (18%, 15%, 9%, and 18%, respectively) than gained (11%, 8%, 8%, and 9%, respectively). Early retirements and furloughs were experienced by 9% of practices, and 18% lost benefits. However, midwifery practice ownership was significantly associated with increased salaries (20.3% vs 7.1%; P < .001) and decreased loss of benefits (7.8% vs 19.9%; P = .002) and furloughs (3.8 vs 10.1%; P = .04). Community-based practice was significantly associated with increased FTE positions (19.0% vs 8.8%; P = .005), part-time positions (17.4% vs 5.1%; P < .001), and salary (19.7% vs 7.0%; P < .001), as well as decreased loss of benefits (11.5% vs 21.1%; P = .02) and early retirement (1.4% vs 6.6%; P = .03). State practice environment and participation in practice decision-making were not directly associated with employment and compensation changes. DISCUSSION: Policies should facilitate midwifery practice ownership and the expansion and integration of community birth settings for greater perinatal care workforce stability, greater flexibility to respond to disasters, and improved patient access to care and health outcomes.

Systematic review and meta-analysis to examine intrapartum interventions, and maternal and neonatal outcomes following immersion in water during labour and waterbirth.

OBJECTIVES: Water immersion during labour using a birth pool to achieve relaxation and pain relief during the first and possibly part of the second stage of labour is an increasingly popular care option in several countries. It is used particularly by healthy women who experience a straightforward pregnancy, labour spontaneously at term gestation and plan to give birth in a midwifery led care setting. More women are also choosing to give birth in water. There is debate about the safety of intrapartum water immersion, particularly waterbirth. We synthesised the evidence that compared the effect of water immersion during labour or waterbirth on intrapartum interventions and outcomes to standard care with no water immersion. A secondary objective was to synthesise data relating to clinical care practices and birth settings that women experience who immerse in water and women who do not. DESIGN: Systematic review and meta-analysis. DATA SOURCES: A search was conducted using CINAHL, Medline, Embase, BioMed Central and PsycINFO during March 2020 and was replicated in May 2021. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: Primary quantitative studies published in 2000 or later, examining maternal or neonatal interventions and outcomes using the birthing pool for labour and/or birth. DATA EXTRACTION AND SYNTHESIS: Full-text screening was undertaken independently against inclusion/exclusion criteria in two pairs. Risk of bias assessment included review of seven domains based on the Robbins-I Risk of Bias Tool. All outcomes were summarised using an OR and 95% CI. All calculations were conducted in Comprehensive Meta-Analysis V.3, using the inverse variance method. Results of individual studies were converted to log OR and SE for synthesis. Fixed effects models were used when I2 was less than 50%, otherwise random effects models were used. The fail-safe N estimates were calculated to determine the number of studies necessary to change the estimates. Begg's test and Egger's regression risk assessed risk of bias across studies. Trim-and-fill analysis was used to estimate the magnitude of effect of the bias. Meta-regression was completed when at least 10 studies provided data for an outcome. RESULTS: We included 36 studies in the review, (N=157 546 participants). Thirty-one studies were conducted in an obstetric unit setting (n=70 393), four studies were conducted in midwife led settings (n=61 385) and one study was a mixed setting (OU and homebirth) (n=25 768). Midwife led settings included planned home and freestanding midwifery unit (k=1), alongside midwifery units (k=1), planned homebirth (k=1), a freestanding midwifery unit and an alongside midwifery unit (k=1) and an alongside midwifery unit (k=1). For water immersion, 25 studies involved women who planned to have/had a waterbirth (n=151 742), seven involved water immersion for labour only (1901), three studies reported on water immersion during labour and waterbirth (n=3688) and one study was unclear about the timing of water immersion (n=215).Water immersion significantly reduced use of epidural (k=7, n=10 993; OR 0.17 95% CI 0.05 to 0.56), injected opioids (k=8, n=27 391; OR 0.22 95% CI 0.13 to 0.38), episiotomy (k=15, n=36 558; OR 0.16; 95% CI 0.10 to 0.27), maternal pain (k=8, n=1200; OR 0.24 95% CI 0.12 to 0.51) and postpartum haemorrhage (k=15, n=63 891; OR 0.69 95% CI 0.51 to 0.95). There was an increase in maternal satisfaction (k=6, n=4144; OR 1.95 95% CI 1.28 to 2.96) and odds of an intact perineum (k=17, n=59 070; OR 1.48; 95% CI 1.21 to 1.79) with water immersion. Waterbirth was associated with increased odds of cord avulsion (OR 1.94 95% CI 1.30 to 2.88), although the absolute risk remained low (4.3 per 1000 vs 1.3 per 1000). There were no differences in any other identified neonatal outcomes. CONCLUSIONS: This review endorses previous reviews showing clear benefits resulting from intrapartum water immersion for healthy women and their newborns. While most included studies were conducted in obstetric units, to enable the identification of best practice regarding water immersion, future birthing pool research should integrate factors that are known to influence intrapartum interventions and outcomes. These include maternal parity, the care model, care practices and birth setting. PROSPERO REGISTRATION NUMBER: CRD42019147001.

Disparities in Adverse Maternal Outcomes Among Five Race and Ethnicity Groups.

Background: Racial/ethnic disparities are evident in adverse maternal health outcomes, but they are shifting due to interventions, initiatives, changing demographics, and the prevalence of preexisting conditions. This study examined the current racial/ethnic disparities in adverse maternal outcomes. Materials and Methods: In a cross-sectional study, the International Classification of Diseases-10 codes for the principal diagnosis and secondary diagnoses were retrieved from the National Inpatient Sample database (2016-2018). A weighted multiple logistic regression model assessed disparities in seven adverse maternal outcomes, including preterm labor, gestational hypertension (GHTN) and diabetes, premature rupture of membranes (PRM), infection of the amniotic cavity (INFAC), placental abruption, and postpartum hemorrhage (PPH). A weighted linear regression model assessed disparities in a composite variable of maternal outcomes. A maternal-specific comorbidity index assessed risk adjustment, and other clinical, sociodemographic, and hospital factors were considered. Results: A total of 2,211,345 pregnancies were included. Preterm labor, GHTN, and placental abruption had the highest raw rate among Black women compared to all races. After adjusting for control variables in the regression analysis, these adverse outcomes also showed the highest odds ratio (OR) among Black women compared to White women (the reference group). Gestational diabetes, PRM, and INFAC had the highest raw rate among Asians/Pacific Islanders (PIs). After adjusting for control variables, these adverse outcomes also showed the highest OR among Asians/PIs compared to White women. The OR for PPH was the highest for Native Americans compared to White women. Furthermore, results of the composite outcome variable indicated that all minority groups experienced the overall poorer maternal outcome than White women. Conclusions: Overall, all four minority women had higher raw rates and also odds of experiencing the studied adverse outcomes than White women. Existing efforts should be strengthened to continue reducing racial/ethnic disparities in adverse maternal outcomes.

Sociodemographic Disparities in Utilization of Childbirth Education.

Childbirth education is a preventive intervention intended to improve maternal and neonatal outcomes that is complementary to antenatal health visits. It is not currently known if disparities in access to childbirth education plays a role in maternal and newborn health disparities in the United States. In this study, we used data from the Pregnancy Risk Assessment Monitoring System (PRAMS) to identify disparities in utilization of childbirth education. We identified lower odds of utilization of childbirth education for pregnant people with lower socioeconomic status, including use of Medicaid, and rural residence. Our analysis indicates that characteristics that reduce access to maternal health care also reduce access to childbirth education. This finding has important implications for communities that use childbirth education as a way to help reduce disparities in maternal or newborn outcomes.

Early Perinatal Workforce Adaptations to the COVID-19 Pandemic.

The objective of this study was to describe the system's initial pandemic response from the perspectives of perinatal health workers and to identify opportunities for improved future preparedness. An exploratory survey was designed to identify perinatal practice changes and workforce challenges during the initial weeks of the COVID-19 pandemic. The survey included baseline data collection and weekly surveys. A total of 181 nurses, midwives, and physicians completed the baseline survey; 84% completed at least 1 weekly survey. Multiple practice changes were reported. About half of respondents (50.8%) felt the changes protected patients, but fewer (33.7%) felt the changes protected themselves. Most respondents providing out-of-hospital birth services (91.4%) reported increased requests for transfer to out-of-hospital birth. Reports of shortages of personnel and supplies occurred as early as the week ending March 23 and were reported by at least 10% of respondents through April 27. Shortages were reported by as many as 38.7% (personal protective equipment), 36.8% (supplies), and 18.5% (personnel) of respondents. This study identified several opportunities to improve the pandemic response. Evaluation of practice changes and timing of supply shortages reported during this emergency can be used to prepare evidence-based recommendations for the next pandemic.

Inpatient palliative care utilisation among patients with gallbladder cancer in the United States: A 10-year perspective.

OBJECTIVES: Gallbladder cancer (GBC) is a rare, poor-prognosis cancer with unique demographics, comorbidities and a paucity of research. This study investigated inpatient palliative care and its associations with demographics, comorbidities (e.g., obesity), length of stay and hospital charges in GBC in US hospitals (2007-2016). METHODS: Data were extracted from the National Inpatient Sample (NIS) database that contains deidentified clinical and nonclinical information for each hospitalisation. Inpatient palliative care utilisation was identified using the International Classification of Diseases (ICD-9 and ICD-10) codes (V66.7 and Z51.5). Generalised regression analysis was conducted with adjustment for variations in predictors. RESULTS: Of the 4921 reported GBC hospitalizations, only 10.3% encountered palliative care. Palliative care was associated with reduced hospital charges by $12,405 per hospitalisation (P < 0.0001) with no change in length of stay. Palliative care utilisation increased over time (P = 0.004). It was associated with age >80 years, with more severe disease, and in-hospital death (P < 0.0001). Obesity had a negative association with palliative care utilisation (P = 0.0029). DISCUSSION: Our novel study found that obese people were less likely to use palliative care services in GBC. Interventions are needed to increase palliative care consultation in GBC patients, particularly in obese patients.

Perinatal Education Participation: Description and Identification of Disparities.

While perinatal education programs are designed to help nulliparous women prepare for childbirth and care of a newborn, many women in the United States do not attend such programs. This article presents partial data from a longitudinal study of 2,884 women aged 18-35 years who birthed their first child in Pennsylvania from 2009-2011. These partial data focused on women's participation in perinatal education and identify disparities in attendance. Overall, 79.1% reported attending one or more perinatal education programs. Women who were White, college educated, aged 30 years or older, and not in poverty were more likely to attend perinatal education programs. These results suggest a need for improved efforts to provide free or low-cost perinatal education to women across the socioeconomic spectrum in the U.S, especially in Pennsylvania.

Association of Delivery Outcomes With the Number of Childbirth Education Sessions.

The objective of this study was to determine whether childbirth education conducted over 3 or more sessions is more effective than courses conducted over 1 or 2 sessions. This was a secondary analysis of 2853 participants in a longitudinal study of women recruited during their first pregnancy. Data on childbirth education attendance were collected during the 1-month postpartum interview. The Kruskal-Wallis test for ranks was used for univariate analysis by the number of class sessions, and logistic regression was used to compare no education with any childbirth education, single-session, 2-session, and 3-or-more-session courses. Primary outcomes included induction of labor, cesarean delivery, use of pain medication, and shared decision-making. Attending 3 or more education sessions was associated with a decreased risk of planned cesarean delivery and increased shared decision-making. Attending any childbirth education was associated with lower odds of using pain medication in labor, reduced odds of planned cesarean delivery, and increased shared decision-making. Childbirth education was not associated with induction of labor. Childbirth education can be provided over 3 or more sessions. This finding can be used to develop evidence-based childbirth education programs.

Systematic Review of Case Reports of Poor Neonatal Outcomes With Water Immersion During Labor and Birth.

Water immersion is a valuable comfort measure in labor, that can be used during the first or second stage of labor. Case reports of adverse outcomes create suspicion about water birth safety, which restricts the availability of water birth in the United States. The objective of this study was to synthesize the information from case reports of adverse water birth events to identify practices associated with these outcomes, and to identify patterns of negative outcomes. The research team conducted a systematic search for cases reports of poor neonatal outcomes with water immersion. Eligible manuscripts reported any adverse neonatal outcome with immersion during labor or birth; or excluded if no adverse outcome was reported or the birth reported was unattended. A qualitative narrative synthesis was conducted to identify patterns in the reports. There were 47 cases of adverse outcomes from 35 articles included in the analysis. There was a pattern of cases of Pseudomonas and Legionella, but other infections were uncommon. There were cases of unexplained neonatal hyponatremia following water birth that need further investigation to determine the mechanism that contributes to this complication. The synthesis was limited by reporting information of interest to pediatricians with little information about water birth immersion practices. These data did not support concerns of water aspiration or cord rupture, but did identify other potential risks. Water immersion guidelines need to address infection risk, optimal management of compromised water-born infants, and the potential association between immersion practice and hyponatremia.

Geospatial variation in caesarean delivery.

Aim: The purpose of this study was to evaluate the variation in caesarean delivery rates across counties in Georgia and to determine whether county-level characteristics were associated with clusters. Design: This was a retrospective, observational study. Methods: Rates of primary and repeat caesarean by maternal county of residence were calculated for 2008 through 2012. Global Moran's I (Spatial Autocorrelation) was used to identify geographic clustering. Characteristics of high and low-rate counties were compared using student's t test and chi-squared test. Results: Spatial analysis of both primary and repeat caesarean rate identified the presence of clusters (Moran's I = 0.375; p < .001). Counties in high-rate clusters had significantly lower access to midwives, more deliveries paid by Medicaid, higher proportion of births for women belonging to racial/ethnic minority groups and were more likely to be rural.
