Abstract
Background Advancing maternal age is increasingly prevalent and is associated with severe maternal morbidity often requiring intensive care unit (ICU) admission. Objectives To describe maternal ICU admissions at a quaternary care hospital in Montreal, Canada, and evaluate the association between maternal age and composite of: need for invasive interventions, ICU stay > 48 h, or maternal death. Methods Chart review of ICU admissions during pregnancy/postpartum (2006-2016); logistic regressions to evaluate the impact of age on outcomes. Results With 5.1 ICU admissions per 1000 deliveries, we included 187 women (mean age 32 ± 6.3 years; 20 (10.7%) ≥ 40 years). The composite outcome occurred in 105 (56.2%) patients; there were two maternal deaths. Age ≥ 40 years increased the odds of invasive interventions (OR 4.03; 95% confidence interval [CI] 1.15-14.1) but not of the composite outcome (OR 2.30; 95% CI 0.66-8.02). Conclusion Peripartum women aged ≥ 40 years had worse outcomes in ICU, with an increased need for invasive interventions.

Abstract
OBJECTIVE To evaluate the association between antibiotic use during pregnancy or early infancy and the risk of neurodevelopmental disorders in children. DESIGN Nationwide population based cohort study and sibling analysis. SETTING Korea's National Health Insurance Service mother-child linked database, 2008-21. PARTICIPANTS All children live born between 2009 and 2020, followed up until 2021 to compare those with and without antibiotic exposure during pregnancy or early infancy (first six months of life). MAIN OUTCOMES MEASURES Autism spectrum disorder, intellectual disorder, language disorder, and epilepsy in children. After 1:1 propensity score matching based on many potential confounders, hazard ratios with 95% confidence interval were estimated using Cox proportional hazard models. A sibling analysis additionally accounted for unmeasured familial factors. RESULTS After propensity score matching, 1 961 744 children were identified for the pregnancy analysis and 1 609 774 children were identified for the early infancy analysis. Although antibiotic exposure during pregnancy was associated with increased risks of all four neurodevelopmental disorders in the overall cohort, these estimates were attenuated towards the null in the sibling analyses (hazard ratio for autism spectrum disorder 1.06, 95% confidence interval 1.01 to 1.12; intellectual disorder 1.00, 0.93 to 1.07; language disorder 1.05, 1.02 to 1.09; and epilepsy 1.03, 0.98 to 1.08). Likewise, no association was observed between antibiotic exposure during early infancy and autism spectrum disorder (hazard ratio 1.00, 0.96 to 1.03), intellectual disorder (1.07, 0.98 to 1.15), and language disorder (1.04, 1.00 to 1.08) in the sibling analyses; however, a small increased risk of epilepsy was observed (1.13, 1.09 to 1.18). The results generally remained consistent across several subgroup and sensitivity analyses, except for slightly elevated risks observed among children who used antibiotics during very early life and those who used antibiotics for more than 15 days. CONCLUSIONS In this large cohort study, antibiotic exposure during pregnancy or early infancy was not associated with an increased risk of autism spectrum disorder, intellectual disorder, or language disorder in children. However, elevated risks were observed in several subgroups such as children using antibiotics during very early life and those with long term antibiotic use, which warrants attention and further investigation. Moreover, antibiotic use during infancy was modestly associated with epilepsy, even after control for indications and familial factors. When prescribing antibiotics to pregnant women and infants, clinicians should carefully balance the benefits of use against potential risks.

Abstract
PURPOSE To identify predictors and develop a scoring model to predict maternal near-miss (MNM) and maternal mortality. METHODS A case-control study of 1,420 women delivered between 2014 and 2020 was conducted. Cases were women with MNM or maternal death, controls were women who had uneventful deliveries directly after women in the cases group. Antenatal characteristics and complications were reviewed. Multivariate logistic regression and Akaike information criterion were used to identify predictors and develop a risk score for MNM and maternal mortality. RESULTS Predictors for MNM and maternal mortality (aOR and score for predictive model) were advanced age (aOR 1.73, 95% CI 1.25-2.39, 1), obesity (aOR 2.03, 95% CI 1.22-3.39, 1), parity ≥ 3 (aOR 1.75, 95% CI 1.27-2.41, 1), history of uterine curettage (aOR 5.13, 95% CI 2.47-10.66, 3), history of postpartum hemorrhage (PPH) (aOR 13.55, 95% CI 1.40-130.99, 5), anemia (aOR 5.53, 95% CI 3.65-8.38, 3), pregestational diabetes (aOR 5.29, 95% CI 1.27-21.99, 3), heart disease (aOR 13.40, 95%CI 4.42-40.61, 5), multiple pregnancy (aOR 5.57, 95% CI 2.00-15.50, 3), placenta previa and/or placenta-accreta spectrum (aOR 48.19, 95% CI 22.75-102.09, 8), gestational hypertension/preeclampsia without severe features (aOR 5.95, 95% CI 2.64-13.45, 4), and with severe features (aOR 16.64, 95% CI 9.17-30.19, 6), preterm delivery <37 weeks (aOR 1.65, 95%CI 1.06-2.58, 1) and < 34 weeks (aOR 2.71, 95% CI 1.59-4.62, 2). A cut-off score of ≥4 gave the highest chance of correctly classified women into high risk group with 74.4% sensitivity and 90.4% specificity. CONCLUSIONS We identified predictors and proposed a scoring model to predict MNM and maternal mortality with acceptable predictive performance.

Abstract
PURPOSE General anesthesia for Cesarean delivery affects maternal and neonatal outcomes. We aimed to evaluate temporal trends in anesthesia management for Cesarean deliveries over 16 years and analyze interinstitutional variations in general anesthesia use in Japan. METHODS In this retrospective cohort study, we obtained patient data from the nationwide health insurance claims database containing data for ten million individuals. We included patients who underwent Cesarean delivery between 1 January 2005 and 31 August 2021. The primary outcome was the use of general anesthesia. We evaluated institutional variations in general anesthesia use in medical facilities using two-level hierarchical logistic regression analyses with median odds ratios and intraclass correlation coefficients. RESULTS The cohort included 86,793 patients who underwent 102,617 Cesarean deliveries at 2,496 institutions. General anesthesia was used in 3.7% (95% confidence interval [CI], 3.6 to 3.9) of all Cesarean deliveries. The temporal trend in the use of general anesthesia decreased gradually from 10.8% in 2005 to 2.9% in 2021 (P for trend < 0.001). The adjusted median odds ratio for medical facilities was 6.1 (95% CI, 5.9 to 6.7), and the intraclass correlation coefficient was 0.52 (95% CI, 0.51 to 0.55). CONCLUSION Although the rate of general anesthesia use for Cesarean delivery in Japan decreased gradually from 2005 to 2021, general anesthesia was used in 3.7% of all Cesarean deliveries. The use of general anesthesia varied significantly across institutions, and 52% of the overall variations in general anesthesia practice can be explained by differences between facilities.

Abstract
BACKGROUND Physiological changes during pregnancy invalidate use of general population reference intervals (RIs) for pregnant people. The complete blood count (CBC) is commonly ordered during pregnancy, but few studies have established pregnancy RIs suitable for contemporary Canadian mothers. Prospective RI studies are challenging to perform during pregnancy while retrospective techniques fall short as pregnancy and health status are not readily available in the laboratory information system (LIS). This study derived pregnancy RIs retrospectively using LIS data linked to provincial perinatal registry data. METHODS A 5-year healthy pregnancy cohort was defined from the British Columbia Perinatal Data Registry and linked to laboratory data from two laboratories. CBC and differential RIs were calculated using direct and indirect approaches. Impacts of maternal and pregnancy characteristics, such as age, body mass index, and ethnicity, on laboratory values were also assessed. RESULTS The cohort contained 143 106 unique term singleton pregnancies, linked to >972 000 CBC results. RIs were calculated by trimester and gestational week. Result trends throughout gestation aligned with previous reports in the literature, although differences in exact RI limits were seen for many tests. Trimester-specific bins may not be appropriate for several CBC parameters that change rapidly within trimesters, including red blood cells (RBCs), some leukocyte parameters, and platelet counts. CONCLUSIONS Combining information from comprehensive clinical databases with LIS data provides a robust and reliable means for deriving pregnancy RIs. The present analysis also illustrates limitations of using conventional trimester bins during pregnancy, supporting use of gestational age or empirically derived bins for defining CBC normal values during pregnancy.

Abstract
BACKGROUND The rates of SMM have been steadily increasing in Arkansas, a southern rural state, which has the 5th highest maternal death rate among the US states. The aims of the study were to test the functionality of the Bateman index in association to SMM, in clustering the risks of pregnancies to SMM, and to study the predictability of SMM using the Bateman index. STUDY DESIGN From the ANGELS database, 72,183 pregnancies covered by Medicaid in Arkansas between 2013 and 2016 were included in this study. The expanded CDC ICD-9/ICD-10 criteria were used to identify SMM. The Bateman comorbidity index was applied in quantifying the comorbidity burden for a pregnancy. Multivariable logistic regressions, KMeans method, and five widely used predictive models were applied respectively for each of the study aims. RESULTS SMM prevalence remained persistently high among Arkansas women covered by Medicaid (195 per 10,000 deliveries) during the study period. Using the Bateman comorbidity index score, the study population was divided into four groups, with a monotonically increasing odds of SMM from a lower score group to a higher score group. The association between the index score and the occurrence of SMM is confirmed with statistical significance: relative to Bateman score falling in 0-1, adjusted Odds Ratios and 95% CIs are: 2.1 (1.78, 2.46) for score in 2-5; 5.08 (3.81, 6.79) for score in 6-9; and 8.53 (4.57, 15.92) for score ≥10. Noticeably, more than one-third of SMM cases were detected from the studied pregnancies that did not have any of the comorbid conditions identified. In the prediction analyses, we observed minimal predictability of SMM using the comorbidity index: the calculated c-statistics ranged between 62% and 67%; the Precision-Recall AUC values are <7% for internal validation and <9% for external validation procedures. CONCLUSIONS The comorbidity index can be used in quantifying the risk of SMM and can help cluster the study population into risk tiers of SMM, especially in rural states where there are disproportionately higher rates of SMM; however, the predictive value of the comorbidity index for SMM is inappreciable.

Abstract
Background: In the United States, Black maternal mortality is 2-4 × higher than that of White maternal mortality, with differences also present in severe maternal morbidity and other measures. However, limited research has comprehensively studied multilevel social determinants of health, and their confounding and effect modification on obstetrical outcomes. Materials and Methods: We performed a retrospective multistate analysis of adult inpatient delivery hospitalizations (Florida, Kentucky, Maryland, New Jersey, New York, North Carolina, and Washington) between 2007 and 2020. Multilevel multivariable models were used to test the confounder-adjusted association for race/ethnicity and the binary outcomes (1) in-hospital mortality or maternal end-organ injury and (2) in-hospital mortality only. Stratified analyses were performed to test effect modification. Results: The confounder-adjusted odds ratio showed that Black (1.33, 95% confidence interval [CI]: 1.30-1.36) and Hispanic (1.14, 95% CI: 1.11-1.18) as compared with White patients were more likely to die in-hospital or experience maternal end-organ injury. For Black and Hispanic patients, stratified analysis showed that findings remained significant in almost all homogeneous strata. After statistical adjustment, Black as compared with White patients were more likely to die in-hospital (1.49, 95% CI: 1.21-1.82). Conclusions: Black and Hispanic patients had higher adjusted odds of in-patient mortality and end-organ damage after birth than White patients. Race and ethnicity serve as strong predictors of health care inequality, and differences in outcomes may reflect broader structural racism and individual implicit bias. Proposed solutions require immense and multifaceted active efforts to restructure how obstetrical care is provided on the societal, hospital, and patient level.

Abstract
BACKGROUND Geographic-based healthcare determinants and choice of anesthesia have been shown to be associated with maternal morbidity and mortality. We explored whether differences in maternal outcomes based on maternal residence, and anesthesia type for cesarean and vaginal birth, exist. METHODS This study was a retrospective multi-state analysis; patient residence was the predictor variable of interest and a composite binary measure of maternal end-organ injury or inpatient mortality was the primary outcome. Our secondary outcomes included a binary measure of anesthesia type for cesarean birth (general vs. neuraxial [NA]) and NA analgesia for vaginal birth (no NA vs. NA). Our predictor variable of interest was patient residency (reference category central metropolitan areas of >1 million population), fringe large metropolitan county, medium metropolitan, small metropolitan, micropolitan, and non-metropolitan or micropolitan county. RESULTS Women residing in micropolitan (OR 1.17; 95% CI 1.09 to 1.27) and non-metropolitan or micropolitan counties (OR 1.14; 95% CI 1.04 to 1.24) had the highest adjusted increased odds of adverse maternal outcomes. Those residing in suburban, medium, and small metropolitan areas underwent general anesthesia less often during cesarean births than those residing in urban areas. Patients residing in micropolitan rural (OR 2.07; 95% CI 2.02 to 2.12) and non-metropolitan or micropolitan (2.25; 95% CI 2.16 to 2.34) counties underwent vaginal births without NA analgesia more than twice as often as those residing in urban areas. CONCLUSIONS Rural-urban disparities in maternal end-organ damage and mortality exist and anesthesia choice may play an important role in these disparate outcomes.

Abstract
BACKGROUND More than 2 million children are conceived annually using assisted reproductive technologies (ARTs), with a similar number conceived using ovulation induction and intrauterine insemination (OI/IUI). Previous studies suggest that ART-conceived children are at increased risk for congenital anomalies (CAs). However, the role of underlying infertility in this risk remains unclear, and ART clinical and laboratory practices have changed drastically over time, particularly there has been an increase in intracytoplasmic sperm injection (ICSI) and cryopreservation. OBJECTIVE To investigate the role of underlying infertility and fertility treatment on CA risks in the first 2 years of life. DESIGN Propensity score-weighted population-based cohort study. SETTING New South Wales, Australia. PARTICIPANTS 851 984 infants (828 099 singletons and 23 885 plural children) delivered between 2009 and 2017. MEASUREMENTS Adjusted risk difference (aRD) in CAs of infants conceived through fertility treatment compared with 2 naturally conceived (NC) control groups-those with and without a parental history of infertility (NC-infertile and NC-fertile). RESULTS The overall incidence of CAs was 459 per 10 000 singleton births and 757 per 10 000 plural births. Compared with NC-fertile singleton control infants (n = 747 018), ART-conceived singleton infants (n = 31 256) had an elevated risk for major genitourinary abnormalities (aRD, 19.0 cases per 10 000 births [95% CI, 2.3 to 35.6]); the risk remained unchanged (aRD, 22 cases per 10 000 births [CI, 4.6 to 39.4]) when compared with NC-infertile singleton control infants (n = 36 251) (that is, after accounting for parental infertility), indicating that ART remained an independent risk. After accounting for parental infertility, ICSI in couples without male infertility was associated with an increased risk for major genitourinary abnormalities (aRD, 47.8 cases per 10 000 singleton births [CI, 12.6 to 83.1]). There was some suggestion of increased risk for CAs after fresh embryo transfer, although estimates were imprecise and inconsistent. There were no increased risks for CAs among OI/IUI-conceived infants (n = 13 574). LIMITATIONS This study measured the risk for CAs only in those children who were born at or after 20 weeks' gestation. Observational study design precludes causal inference. Many estimates were imprecise. CONCLUSION Patients should be counseled on the small increased risk for genitourinary abnormalities after ART, particularly after ICSI, which should be avoided in couples without problems of male infertility.

Abstract
BACKGROUND Heterogeneity in reported outcomes can limit the synthesis of research evidence. A core outcome set informs what outcomes are important and should be measured as a minimum in all future studies. We report the development of a core outcome set applicable to observational and interventional studies of pregnant women with multimorbidity. METHODS We developed the core outcome set in four stages: (i) a systematic literature search, (ii) three focus groups with UK stakeholders, (iii) two rounds of Delphi surveys with international stakeholders and (iv) two international virtual consensus meetings. Stakeholders included women with multimorbidity and experience of pregnancy in the last 5 years, or are planning a pregnancy, their partners, health or social care professionals and researchers. Study adverts were shared through stakeholder charities and organisations. RESULTS Twenty-six studies were included in the systematic literature search (2017 to 2021) reporting 185 outcomes. Thematic analysis of the focus groups added a further 28 outcomes. Two hundred and nine stakeholders completed the first Delphi survey. One hundred and sixteen stakeholders completed the second Delphi survey where 45 outcomes reached Consensus In (≥70% of all participants rating an outcome as Critically Important). Thirteen stakeholders reviewed 15 Borderline outcomes in the first consensus meeting and included seven additional outcomes. Seventeen stakeholders reviewed these 52 outcomes in a second consensus meeting, the threshold was ≥80% of all participants voting for inclusion. The final core outcome set included 11 outcomes. The five maternal outcomes were as follows: maternal death, severe maternal morbidity, change in existing long-term conditions (physical and mental), quality and experience of care and development of new mental health conditions. The six child outcomes were as follows: survival of baby, gestational age at birth, neurodevelopmental conditions/impairment, quality of life, birth weight and separation of baby from mother for health care needs. CONCLUSIONS Multimorbidity in pregnancy is a new and complex clinical research area. Following a rigorous process, this complexity was meaningfully reduced to a core outcome set that balances the views of a diverse stakeholder group.

Abstract
BACKGROUND Maternal multiple long-term conditions are associated with adverse outcomes for mother and child. We conducted a qualitative study to inform a core outcome set for studies of pregnant women with multiple long-term conditions. METHODS Women with two or more pre-existing long-term physical or mental health conditions, who had been pregnant in the last five years or planning a pregnancy, their partners and health care professionals were eligible. Recruitment was through social media, patients and health care professionals' organisations and personal contacts. Participants who contacted the study team were purposively sampled for maximum variation. Three virtual focus groups were conducted from December 2021 to March 2022 in the United Kingdom: (i) health care professionals (n = 8), (ii) women with multiple long-term conditions (n = 6), and (iii) women with multiple long-term conditions (n = 6) and partners (n = 2). There was representation from women with 20 different physical health conditions and four mental health conditions; health care professionals from obstetrics, obstetric/maternal medicine, midwifery, neonatology, perinatal psychiatry, and general practice. Participants were asked what outcomes should be reported in all studies of pregnant women with multiple long-term conditions. Inductive thematic analysis was conducted. Outcomes identified in the focus groups were mapped to those identified in a systematic literature search in the core outcome set development. RESULTS The focus groups identified 63 outcomes, including maternal (n = 43), children's (n = 16) and health care utilisation (n = 4) outcomes. Twenty-eight outcomes were new when mapped to the systematic literature search. Outcomes considered important were generally similar across stakeholder groups. Women emphasised outcomes related to care processes, such as information sharing when transitioning between health care teams and stages of pregnancy (continuity of care). Both women and partners wanted to be involved in care decisions and to feel informed of the risks to the pregnancy and baby. Health care professionals additionally prioritised non-clinical outcomes, including quality of life and financial implications for the women; and longer-term outcomes, such as children's developmental outcomes. CONCLUSIONS The findings will inform the design of a core outcome set. Participants' experiences provided useful insights of how maternity care for pregnant women with multiple long-term conditions can be improved.

Despite Increased Disease Activity, Women who Attended a Dedicated Inflammatory Bowel Disease and Pregnancy Clinic Had Infants With Higher Apgar Scores: A Population-Based Study.

Abstract
BACKGROUND Attendance at a subspecialty pregnancy clinic for women with inflammatory bowel disease (IBD) improves disease-specific pregnancy knowledge. We examined the impact of attendance at a dedicated IBD-pregnancy clinic on IBD and perinatal outcomes. METHODS Using linked administrative databases in Alberta, Canada (2012-2019), we identified 1061 pregnant women with IBD who delivered singleton liveborn infants in-hospital who did (n = 314) and did not attend (n = 747) the clinic. Propensity score weighted multivariable log-binomial and multinomial logistic regression models were used to determine the risk of IBD and perinatal outcomes. RESULTS The median number of clinic visits was 3 (Q1-Q3, 3-5), with 34.7% completing a preconception consultation. A greater proportion of women who attended lived near the clinic, were nulliparous, had a disease flare prior to pregnancy, and were on maintenance IBD medication (P < .05). Women who attended had increased risks of a disease flare during pregnancy (adjusted risk ratio [aRR], 2.02; 95% CI, 1.45-2.82), an IBD-related emergency department visit during pregnancy (aRR, 2.66; 95% CI, 1.92-3.68), and cesarean delivery (aRR, 1.78; 95% CI, 1.23-2.57). Despite this, clinic attendees had a decreased risk of delivering an infant with a low Apgar score at 1 minute (risk ratio [RR], 0.49; 95% CI, 0.32-0.76) and 5 minutes (RR, 0.32; 95% CI, 0.12-0.87). CONCLUSIONS Women who attended a dedicated IBD-pregnancy clinic were more likely to have a disease flare prior to pregnancy, reflecting a more severe disease phenotype, but had similar perinatal outcomes and infants with better Apgar scores at birth. Our study suggests the value of these subspecialty clinics in providing enhanced IBD-specific prenatal care.

Maternal comorbidity and adverse perinatal outcomes in survivors of adolescent and young adult cancer: A cohort study. BJOG 2023; 130:779-789. [PMID: 36655360 PMCID: PMC10401611 DOI: 10.1111/1471-0528.17380] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2022] [Revised: 10/04/2022] [Accepted: 10/19/2022] [Indexed: 01/20/2023]
Abstract
OBJECTIVE To evaluate risks of preterm birth (PTB) and severe maternal morbidity (SMM) in female survivors of adolescent and young adult cancer and assess maternal comorbidity as a potential mechanism. To determine whether associations differ by use of assisted reproductive technology (ART). DESIGN Retrospective cohort. SETTING Commercially insured females in the USA. SAMPLE Females with live births from 2000-2019 within a de-identified US administrative health claims data set. METHODS Log-binomial regression models estimated relative risks of PTB and SMM by cancer status and tested for effect modification. Causal mediation analysis evaluated the proportions explained by maternal comorbidity. MAIN OUTCOME MEASURES PTB and SMM. RESULTS Among 46 064 cancer survivors, 2440 singleton births, 214 multiple births and 2590 linked newborns occurred after cancer diagnosis. In singleton births, the incidence of PTB was 14.8% in cancer survivors versus 12.4% in females without cancer (aRR 1.19, 95% CI 1.06-1.34); the incidence of SMM was 3.9% in cancer survivors versus 2.4% in females without cancer (aRR 1.44, 95% CI 1.13-1.83). Cancer survivors had more maternal comorbidities before and during pregnancy; 26% of the association between cancer and PTB and 30% of the association between cancer and SMM was mediated by maternal comorbidities. Tests for effect modification of cancer status on perinatal outcomes by ART were non-significant. CONCLUSIONS Preterm birth and SMM risks were modestly increased after cancer. Significant proportions of elevated risks may result from increased comorbidities. ART did not significantly modify the association between adolescent and young adult cancer and adverse perinatal outcomes. The prevention and treatment of comorbidities provides an opportunity to improve perinatal outcomes among cancer survivors.

Prenatal and Infant Exposure to Acid-Suppressive Medications and Risk of Allergic Diseases in Children. JAMA Pediatr 2023; 177:267-277. [PMID: 36622684 PMCID: PMC9857801 DOI: 10.1001/jamapediatrics.2022.5193] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/25/2022] [Accepted: 10/15/2022] [Indexed: 01/10/2023]
Abstract
Importance Existing observational data have indicated positive associations of acid-suppressive medication (ASM) use in prenatal and early life with allergic diseases in children; however, no study to date has accounted for confounding by indication or within-familial factors. Objective To evaluate the association of prenatal or infant exposure to ASMs with risk of allergic diseases in children. Design, Setting, and Participants This nationwide, cohort study included data from South Korea's National Health Insurance Service mother-child-linked database from January 1, 2007, to December 31, 2020. Participants included mother-child pairs of neonates born from April 1, 2008, to December 31, 2019. Exposures Prenatal and infant exposure to ASMs (histamine 2 receptor antagonists [H2RAs] and proton pump inhibitors [PPIs]). Main Outcomes and Measures Composite and individual outcomes of allergic diseases (asthma, allergic rhinitis, atopic dermatitis, and food allergy) in children (followed up to 13 years of age) were assessed. The ASM-exposed individuals were compared with unexposed individuals in propensity score (PS)-matched and sibling-matched analyses to control for various potential confounders and within-familial factors. Hazard ratios (HRs) with 95% CIs were estimated using Cox proportional hazards regression models. Results The study included 4 149 257 mother-child pairs. Prenatal exposure analyses included 808 067 PS-matched pairs (763 755 received H2RAs, 36 529 received PPIs) among women with a mean (SD) age of 31.8 (4.2) years. The PS-matched HR was 1.01 (95% CI, 1.01-1.02) for allergic diseases overall (asthma: HR, 1.02 [95% CI, 1.01-1.03]; allergic rhinitis: HR, 1.02 [95% CI, 1.01-1.02]; atopic dermatitis: HR, 1.02 [95% CI, 1.01-1.02]; food allergy: HR, 1.03 [95% CI, 0.98-1.07]); in sibling-matched analyses, the HRs were similar to those of PS-matched analyses but were not significant (allergic diseases: HR, 1.01; 95% CI, 0.997-1.01). Infant exposure analyses included 84 263 PS-matched pairs (74 188 received H2RAs, 7496 received PPIs). The PS-matched HR was 1.06 (95% CI, 1.05-1.07) for allergic diseases overall (asthma: HR, 1.16 [95% CI, 1.14-1.18]; allergic rhinitis: HR, 1.02 [95% CI, 1.01-1.03]; atopic dermatitis: HR, 1.05 [95% CI, 1.02-1.08]; food allergy: HR, 1.28 [95% CI, 1.10-1.49]); asthma risk (HR, 1.13; 95% CI, 1.09-1.17) remained significantly higher among children exposed to ASMs during infancy in sibling-matched analyses. The findings were similar for H2RAs and PPIs analyzed separately and were robust across all sensitivity analyses. Conclusions and Relevance The findings of this cohort study suggest that there is no association between prenatal exposure to ASMs and allergic diseases in offspring. However, infant exposure to ASMs was associated with a higher risk of developing asthma, although the magnitude was more modest than previously reported. Clinicians should carefully weigh the benefits of prescribing ASMs to children, accompanied by subsequent close monitoring for any clinically relevant safety signals.

Choi EY, Jeong HE, Noh Y, Choi A, Yon DK, Han JY, Sung JH, Choe SA, Shin JY. Neonatal and maternal adverse outcomes and exposure to nonsteroidal anti-inflammatory drugs during early pregnancy in South Korea: A nationwide cohort study. PLoS Med 2023; 20:e1004183. [PMID: 36848338 PMCID: PMC9970080 DOI: 10.1371/journal.pmed.1004183] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/21/2022] [Accepted: 01/24/2023] [Indexed: 03/01/2023] Open
Abstract
BACKGROUND Existing data on the use of nonsteroidal anti-inflammatory drugs (NSAIDs) during late pregnancy is well established, providing assurance. However, the use of NSAIDs during early pregnancy remains inconclusive owing to conflicting findings on adverse neonatal outcomes as well as the limited data on adverse maternal outcomes. Therefore, we sought to investigate whether early prenatal exposure to NSAIDs was associated with neonatal and maternal adverse outcomes. METHODS AND FINDINGS We conducted a nationwide, population-based cohort study using Korea's National Health Insurance Service (NHIS) database with a mother-offspring cohort constructed and validated by the NHIS to include all live births in women aged 18 to 44 years between 2010 and 2018. We defined exposure to NSAIDs as at least two records of NSAID prescriptions during early pregnancy (first 90 days of pregnancy for congenital malformations and first 19 weeks for nonmalformation outcomes) and compared against three distinct referent groups of (1) unexposed, no NSAID prescription during the 3 months before pregnancy start to end of early pregnancy; (2) acetaminophen-exposed, at least two acetaminophen prescriptions during early pregnancy (i.e., active comparator); and (3) past users, at least two NSAID prescriptions before the start of pregnancy but no relevant prescriptions during pregnancy. Outcomes of interest were adverse birth outcomes of major congenital malformations and low birth weight and adverse maternal outcomes of antepartum hemorrhage and oligohydramnios. We estimated relative risks (RRs) with 95% CIs using generalized linear models within a propensity score (PS) fine stratification weighted cohort that accounted for various potential confounders of maternal sociodemographic characteristics, comorbidities, co-medication use, and general markers of burden of illness. Of 1.8 million pregnancies in the PS weighted analyses, exposure to NSAIDs during early pregnancy was associated with slightly increased risks for neonatal outcomes of major congenital malformations (PS-adjusted RR, 1.14 [CI, 1.10 to 1.18]) and low birth weight (1.29 [1.25 to 1.33]), and for maternal outcome of oligohydramnios (1.09 [1.01 to 1.19]) but not antepartum hemorrhage (1.05 [0.99 to 1.12]). The risks of overall congenital malformations, low birth weight, and oligohydramnios remained significantly elevated despite comparing NSAIDs against acetaminophen or past users. Risks of adverse neonatal and maternal outcomes were higher with cyclooxygenase-2 selective inhibitors or use of NSAIDs for more than 10 days, whereas generally similar effects were observed across the three most frequently used individual NSAIDs. Point estimates were largely consistent across all sensitivity analyses, including the sibling-matched analysis. Main limitations of this study are residual confounding by indication and from unmeasured factors. CONCLUSIONS This large-scale, nationwide cohort study found that exposure to NSAIDs during early pregnancy was associated with slightly higher risks of neonatal and maternal adverse outcomes. Clinicians should therefore carefully weigh the benefits of prescribing NSAIDs in early pregnancy against its modest, but possible, risk of neonatal and maternal outcomes, where if possible, consider prescribing nonselective NSAIDs for <10 days, along with continued careful monitoring for any safety signals.

Abstract
OBJECTIVE To determine whether longitudinal health data accounts for end-organ injury or death in the setting of chronic hypertension. DESIGN Cohort of 64 799 deliveries to 61 854 women. SETTING US claims data for the preiod 2008-2019. POPULATION Women with a delivery hospitalisation and chronic hypertension. METHODS Risk for a composite of acute end-organ injury or death during the delivery hospitalisation and 30 days postpartum was analysed. Adjusted logistic regression models were derived with discrimination for each model estimated by the C-statistic. Poisson regression was used to estimate adjusted risk ratios. Starting with models using data from pregnancy, further adjustment was performed accounting for healthcare use in the year prior to pregnancy, including hospitalisations, emergency department encounters, prescription medications and pre-pregnancy diagnoses. MAIN OUTCOME MEASURES Acute end-organ injury or death. RESULTS The composite outcome occurred among 5.7% of 64 799 deliveries. For patients with commercial insurance, filling non-hypertensive medications from ≥11 different classes, compared with none (adjusted risk ratio, aRR 4.07, 95% CI 2.86-5.79), three or more hospitalisations before pregnancy, compared with none (aRR 4.75, 95% CI 3.46-6.52), and chronic kidney disease diagnosed in the year before pregnancy (aRR 2.35, 95% CI 1.88, 2.94) were associated with increased risk. For pregnancies covered by commercial insurance, the C-statistic increased from 0.615 (95% CI 0.599-0.630) in the model with pregnancy data only to 0.796 (95% CI 0.783-0.808) for the model additionally including healthcare use in the year before pregnancy. Findings with Medicaid were similar. CONCLUSIONS Prepregnancy care use predicted adverse maternal outcomes. These data may be important in risk stratification.

Trend in neuraxial morphine use and postoperative analgesia after cesarean delivery in Japan from 2005 to 2020. Sci Rep 2022; 12:17234. [PMID: 36241762 PMCID: PMC9568599 DOI: 10.1038/s41598-022-22165-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2022] [Accepted: 10/11/2022] [Indexed: 01/06/2023] Open
Abstract
The increasing rate of cesarean deliveries warrants obstetric anesthesiologists to deliver high-quality post-cesarean delivery analgesia. The aim of this study was to evaluate the temporal trends in the use of neuraxial morphine for cesarean deliveries and to describe the current postoperative analgesia practices. A retrospective cohort study using nationwide health insurance claims databases was conducted from 2005 to 2020 in Japan. Pregnant women who had undergone cesarean deliveries were included. The annual rate of neuraxial morphine use was extracted and analyzed. Additionally, we explored the patient- and facility-level factors associated with neuraxial morphine use through a multilevel logistic regression analysis. The cohort included 65,208 cesarean delivery cases from 2275 institutions. The prevalence of neuraxial morphine use was 16.0% (95% confidence interval [CI], 15.8-16.3) in the overall cohort. Intrathecal morphine was used in 20.6% (95% CI, 20.2-21.0) of spinal anesthesia cases. The trend in neuraxial morphine use steadily increased from 2005 to 2020. The significant predictors of neuraxial morphine use included spinal anesthesia, recent surgery, large medical facilities, and academic hospitals. Variations in the utilization of postoperative analgesia were observed. Our study described the current trend of neuraxial morphine use and the variation in postoperative analgesia practice in Japan.

Current Epidemiology of the General Anesthesia Practice for Cesarean Delivery Using a Nationwide Claims Database in Japan: A Descriptive Study. J Clin Med 2022; 11:jcm11164808. [PMID: 36013045 PMCID: PMC9409718 DOI: 10.3390/jcm11164808] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2022] [Revised: 08/01/2022] [Accepted: 08/16/2022] [Indexed: 11/17/2022] Open
Abstract
The current status of general anesthesia practice for cesarean delivery in Japan remains unknown. Therefore, using a nationwide claims database, we aimed to investigate general anesthesia use for cesarean delivery over a period of 15 years, and to analyze the general anesthesia practice in Japan. Patients who claimed the Japanese general anesthesia claim code (L008) for cesarean delivery between 1 January 2005, and 31 March 2020, were analyzed. Primary endpoint was the prevalence of general anesthesia use. We used two definitions of general anesthesia: L008 code only (insurance definition) and combination of the L008 code with muscle relaxant use (clinical definition). The general anesthesia claim cohort (L008) included 10,972 cesarean deliveries at 1111 institutions from 2005 to 2020. Muscle relaxants were used in 27.3% of L008 claims cases. The rate of general anesthesia use for cesarean delivery ranged from 3.9% in clinical definition to 14.4% in insurance definition of all cesarean deliveries. We observed a temporal trend of gradual decrease in general anesthesia use, regardless of its definition (p for trend < 0.001). We recommend the clinical definition of general anesthesia as the combination of L008 code and muscle relaxant use in a claims-based approach.

Travel time to delivery, antenatal care, and birth outcomes: a population-based cohort of uncomplicated pregnancies in British Columbia, 2012-2019. JOURNAL OF OBSTETRICS AND GYNAECOLOGY CANADA 2022; 44:886-894. [PMID: 35525429 DOI: 10.1016/j.jogc.2022.04.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2021] [Revised: 04/01/2022] [Accepted: 04/04/2022] [Indexed: 10/18/2022]
Abstract
OBJECTIVE Health policy and system leaders need to know whether long travel time to a delivery facility adversely affects birth outcomes. In this study, we estimated associations between travel time to delivery and outcomes in low-risk pregnancies. METHODS This population-based cohort included all singleton births without obstetric comorbidities or intrapartum facility transfers in British Columbia, Canada, from 2012 to 2019. Travel time was measured from maternal residential postal code to delivery facility using road network analysis. We estimated associations between travel time and severe maternal morbidity, stillbirth, preterm birth, and small-for-gestational age (SGA) and large-for-gestational age (LGA) status using logistic regression, adjusted for confounders (adjusted odds ratios [aORs]). To examine variations in associations between travel time and outcomes by antenatal care utilization, we stratified models by antenatal care categories. RESULTS Of 232 698 births, 3.8% occurred at a facility ≥60 minutes from the maternal residence. Obesity, adolescent age, substance use, inadequate prenatal care, and low socioeconomic status were more frequent among those traveling farther for delivery. Travel time ≥120 minutes was associated with increased risk of stillbirth (aOR 1.8; 95% CI 1.2-2.8), preterm birth (aOR 2.3; 95% CI 2 1-2.5), LGA (aOR 1.5; 95% CI 1.4-1.6), and severe maternal morbidity (aOR 1.5; 95% CI 1.2-1.8), but not SGA (aOR 1.0; 95% CI 0.8-1.1), when compared with a travel time of 1-29 minutes. Risk of stillbirth was greatest with inadequate and intensive (adequate plus) antenatal care but persisted for severe maternal morbidity, preterm birth, and LGA across categories. CONCLUSION Longer travel time to delivery was associated with increased risk of adverse outcomes in low-risk pregnancies after adjusting for confounding factors. Associations were stronger among those with inadequate antenatal care.

Abstract
RATIONALE AND OBJECTIVES Obstetrical ultrasound imaging is an important part of prenatal care, though not all patients have readily available access to ultrasound services. This study aimed to assess the association between sociodemographic and geographic factors and (1) having a second trimester complete obstetrical ultrasound and (2) overall obstetrical ultrasound utilization. METHODS All pregnancies and obstetrical ultrasound exams billed from 2014-2018 in Saskatchewan, Canada were identified from province-wide databases. Generalized estimating equation (GEE) models with binomial and Poisson distributions were used to identify factors associated with having a second trimester ultrasound and overall obstetrical ultrasound utilization, respectively. RESULTS 80,536 pregnancies from 57,881 individuals were included. Of 57,186 pregnancies carried to ≥23 weeks, a second trimester ultrasound was performed in 50,180 (87.7%). Patients living in rural areas (adjusted odds ratio [aOR], 0.70; 95% confidence interval [CI], 0.63-0.77; p <0.0001), remote areas (aOR, 0.35 for greatest vs. least remoteness level; 95% CI, 0.32-0.39; p <0.0001), and status First Nations individuals (aOR, 0.50; 95% CI, 0.46-0.53; p <0.0001) were less likely to have a second trimester ultrasound. Patients living in higher income neighbourhoods (aOR, 1.86 for highest vs. lowest quintile; 95% CI, 1.62-2.13; p <0.0001) were more likely to have a second trimester ultrasound. GEE Poisson regression analysis demonstrated these same factors, except rural residence, were associated with overall obstetrical ultrasound utilization. CONCLUSION Substantial disparities in obstetrical ultrasound utilization exist among patients in remote geographic areas, Indigenous peoples, and patients in low income neighbourhoods. Addressing barriers which these demographic groups face in accessing ultrasound imaging is critical to ensure health equity.

Abstract
ObjectiveTo assess differences in rates of postpartum hospitalisations among homeless women compared with non-homeless women.DesignCross-sectional secondary analysis of readmissions and emergency department (ED) utilisation among postpartum women using hierarchical regression models adjusted for age, race/ethnicity, insurance type during delivery, delivery length of stay, maternal comorbidity index score, other pregnancy complications, neonatal complications, caesarean delivery, year fixed effect and a birth hospital random effect.SettingNew York statewide inpatient and emergency department databases (2009–2014).Participants82 820 and 1 026 965 postpartum homeless and non-homeless women, respectively.Main outcome measuresPostpartum readmissions (primary outcome) and postpartum ED visits (secondary outcome) within 6 weeks after discharge date from delivery hospitalisation.ResultsHomeless women had lower rates of both postpartum readmissions (risk-adjusted rates: 1.4% vs 1.6%; adjusted OR (aOR) 0.87, 95% CI 0.75 to 1.00, p=0.048) and ED visits than non-homeless women (risk-adjusted rates: 8.1% vs 9.5%; aOR 0.83, 95% CI 0.77 to 0.90, p<0.001). A sensitivity analysis stratifying the non-homeless population by income quartile revealed significantly lower hospitalisation rates of homeless women compared with housed women in the lowest income quartile. These results were surprising due to the trend of postpartum hospitalisation rates increasing as income levels decreased.ConclusionsTwo factors likely led to lower rates of hospital readmissions among homeless women. First, barriers including lack of transportation, payment or childcare could have impeded access to postpartum inpatient and emergency care. Second, given New York State’s extensive safety net, discharge planning such as respite and sober living housing may have provided access to outpatient care and quality of life, preventing adverse health events. Additional research using outpatient data and patient perspectives is needed to recognise how the factors affect postpartum health among homeless women. These findings could aid in lowering readmissions of the housed postpartum population.

Abstract
IMPORTANCE Characterizing and addressing racial and ethnic disparities in peripartum pain assessment and treatment is a national priority. OBJECTIVE To evaluate the association of race and ethnicity with the provision and timing of an epidural blood patch (EBP) for management of postdural puncture headache in obstetric patients. DESIGN, SETTING, AND PARTICIPANTS This cross-sectional study used New York State hospital discharge records from January 1, 1998, to December 31, 2016, from mothers 15 to 49 years of age with a postdural puncture headache after neuraxial analgesia or anesthesia for childbirth. Statistical analysis was performed from February 2020 to February 2022. EXPOSURES Patients' race and ethnicity (reported as provided by each participating hospital; the method of determining race and ethnicity [ie, self-reported or not] cannot be determined from the data) were categorized into non-Hispanic White (reference group), non-Hispanic Black, Hispanic, and other race and ethnicity (including Asian and Pacific Islander, American Indian, Alaskan Native, and other). MAIN OUTCOMES AND MEASURES The primary outcome was the rate of EBP use. The secondary outcome was the interval (days) between hospital admission and provision of EBP. Odds ratios (ORs) and 95% CIs of EBP use associated with race and ethnicity were estimated using mixed-effect logistic regression models, adjusting for patient and hospital characteristics. RESULTS During the study period, 8921 patients (mean [SD] age, 30 [6] years; 1028 [11.5%] Black; 1301 [14.6%] Hispanic; 4960 [55.6%] White; and 1359 [15.2%] other race and ethnicity) with postdural puncture headache were identified among 1.9 million deliveries with a neuraxial procedure. Of these 8921 patients, 4196 (47.0%; 95% CI, 46.0%-48.1%) were managed with an EBP. A total of 2650 White patients (53.4%; 95% CI, 52.0%-54.8%) used an EBP; this rate was significantly higher than that among Hispanic patients (41.7% [543]; 95% CI, 39.9%-44.5%), Black patients (35.7% [367]; 95% CI, 32.8%-38.7%), or patients of other race and ethnicity (35.2% [478]; 95% CI, 32.6%-37.8%). Timing of EBP was at a median of 2 days (IQR, 2-3 days) after hospital admission for White patients compared with a median of 3 days (IQR, 2-4 days) for Hispanic patients, Black patients, and patients of other race and ethnicity (P < .001 for the comparison with White patients). After adjustment for patient and hospital characteristics, the EBP rate was not different between White and Hispanic patients (adjusted OR, 1.11; 95% CI, 0.94-1.30). It was significantly lower for Black patients (adjusted OR, 0.80; 95% CI, 0.67-0.94) and patients of other races and ethnicities (adjusted OR, 0.85; 95% CI, 0.73-0.99). CONCLUSIONS AND RELEVANCE In this study, significant racial and ethnic disparities in the management of postdural puncture headache with EBP were observed, with both lower rates and delayed timing, which may be associated with long-term adverse effects.

Abstract
BACKGROUND Despite the importance of prenatal care, quality measurement efforts have focused on the number of prenatal visits, or prenatal care adequacy, rather than the services received. It is unknown whether attending more prenatal visits is associated with receiving more guideline-based prenatal care services. The relationship between guideline-based prenatal care and patients' clinical and sociodemographic characteristics has also not been studied. OBJECTIVE This study aimed to measure the receipt of guideline-based prenatal care among pregnant patients and to describe the association between guideline-based prenatal care and the number of prenatal visits and other patient characteristics. STUDY DESIGN This was a retrospective descriptive cohort study of 176,092 pregnancy episodes between 2016 and 2019. We used de-identified administrative claims data on commercial enrollees across the United States from the OptumLabs Data Warehouse. We identified the following 8 components of prenatal care that are universally recommended by the American College of Obstetricians and Gynecologists and other guideline-issuing organizations: testing for sexually transmitted infections, obstetric laboratory test panel, urine culture, urinalysis, anatomy scan ultrasound, oral glucose tolerance test, tetanus, diphtheria, and pertussis vaccine, and group B Streptococcus test. We measured the proportion of pregnant patients who received each of these guideline-based services at the appropriate gestational age. We measured the association between guideline-based services and the number of prenatal visits and prenatal care adequacy. We described variation of guideline-based care according to patient age, comorbidities, high deductible health plan enrollment, and their county's rurality, health professional shortage area status, racial composition, median income, and educational attainment. RESULTS The 176,092 pregnancy episodes were mostly among patients aged 25 to 34 years (63%) with few pregnancy comorbidities (81%) and living in urban areas (92%). Guideline-based care varied by service, from 51% receiving a timely urinalysis to 90% receiving an anatomy scan and 91% completing testing for sexually transmitted infections. Patients with at least 4 prenatal visits received, on average, 6 of the 8 guideline-based services. Guideline-based care did not increase with additional prenatal visits and varied by patient characteristics. Rates of tetanus, diphtheria, and pertussis vaccination were lower in counties with high proportions of minoritized populations, lower education, and lower income. CONCLUSION In this commercially insured population, receipt of guideline-based care was not universal, did not increase with the number of prenatal visits, and varied by patient- and area-level characteristics. Measuring guideline-based care is feasible and may capture quality of prenatal care better than visit count or adequacy alone.

First-trimester exposure to benzodiazepines and risk of congenital malformations in offspring: A population-based cohort study in South Korea. PLoS Med 2022; 19:e1003945. [PMID: 35235572 PMCID: PMC8926183 DOI: 10.1371/journal.pmed.1003945] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/27/2021] [Revised: 03/16/2022] [Accepted: 02/13/2022] [Indexed: 11/26/2022] Open
Abstract
BACKGROUND Benzodiazepines are frequently prescribed during pregnancy; however, evidence about possible teratogenicity is equivocal. We aimed to evaluate the association between first-trimester benzodiazepine use and the risk of major congenital malformations. METHODS AND FINDINGS Using Korea's nationwide healthcare database, we conducted a population-based cohort study of women who gave birth during 2011 to 2018 and their live-born infants. The exposure was defined as one or more benzodiazepine prescriptions during the first trimester. We determined the relative risks (RRs) and confidence intervals (CIs) of overall congenital malformations and 12 types of organ-specific malformations. Infants were followed from birth to death or 31 December 2019, whichever came first (up to 8 years of age). Propensity score fine stratification was employed to control for 45 potential confounders. Among a total of 3,094,227 pregnancies, 40,846 (1.3%) were exposed to benzodiazepines during the first trimester (mean [SD] age, 32.4 [4.1] years). The absolute risk of overall malformations was 65.3 per 1,000 pregnancies exposed to benzodiazepines versus 51.4 per 1,000 unexposed pregnancies. The adjusted RR was 1.09 (95% CI 1.05 to 1.13, p < 0.001) for overall malformations and 1.15 (1.10 to 1.21, p < 0.001) for heart defects. Based on mean daily lorazepam-equivalent doses, the adjusted RRs for overall malformations and heart defects were 1.05 (0.99 to 1.12, p = 0.077) and 1.12 (1.04 to 1.21, p = 0.004) for <1 mg/day and 1.26 (1.17 to 1.36, p < 0.001) and 1.31 (1.19 to 1.45, p < 0.001) for >2.5 mg/day doses, respectively, suggesting a dose-response relationship. A small but significant increase in risk for overall and heart defects was detected with several specific agents (range of adjusted RRs: 1.08 to 2.43). The findings were robust across all sensitivity analyses, and negative control analyses revealed a null association. Study limitations include possible exposure misclassification, residual confounding, and restriction to live births. CONCLUSIONS In this large nationwide cohort study, we found that first-trimester benzodiazepine exposure was associated with a small increased risk of overall malformations and heart defects, particularly at the higher daily dose. The absolute risks and population attributable fractions were modest. The benefits of benzodiazepines for their major indications must be considered despite the potential risks; if their use is necessary, the lowest effective dosage should be prescribed to minimize the risk.

Population-wide contribution of medically assisted reproductive technologies to overall births in Australia: temporal trends and parental characteristics. Hum Reprod 2022; 37:1047-1058. [DOI: 10.1093/humrep/deac032] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2021] [Revised: 01/27/2022] [Indexed: 11/14/2022] Open
Abstract
Abstract
STUDY QUESTION
In a country with supportive funding for medically assisted reproduction (MAR) technologies, what is the proportion of MAR births over-time?
SUMMARY ANSWER
In 2017, 6.7% of births were conceived by MAR (4.8% ART and 1.9% ovulation induction (OI)/IUI) with a 55% increase in ART births and a stable contribution from OI/IUI births over the past decade.
WHAT IS KNOWN ALREADY
There is considerable global variation in utilization rates of ART despite a similar infertility prevalence worldwide. While the overall contribution of ART to national births is known in many countries because of ART registries, very little is known about the contribution of OI/IUI treatment or the socio-demographic characteristics of the parents. Australia provides supportive public funding for all forms of MAR with no restrictions based on male or female age, and thus provides a unique setting to investigate the contribution of MAR to national births as well as the socio-demographic characteristics of parents across the different types of MAR births.
STUDY DESIGN, SIZE, DURATION
This is a novel population-based birth cohort study of 898 084 births using linked ART registry data and administrative data including birth registrations, medical services, pharmaceuticals, hospital admissions and deaths. Birth (a live or still birth of at least one baby of ≥400 g birthweight or ≥20 weeks’ gestation) was the unit of analysis in this study. Multiple births were considered as one birth in our analysis.
PARTICIPANTS/MATERIALS, SETTING, METHODS
This study included a total of 898 084 births (606 488 mothers) in New South Wales and the Australian Capital Territory, Australia 2009–2017. We calculated the prevalence of all categories of MAR-conceived births over the study period. Generalized estimating equations were used to examine the association between parental characteristics (parent’s age, parity, socio-economic status, maternal country of birth, remoteness of mother’s dwelling, pre-existing medical conditions, smoking, etc.) and ART and OI/IUI births relative to naturally conceived births.
MAIN RESULTS AND THE ROLE OF CHANCE
The proportion of MAR births increased from 5.1% of all births in 2009 to 6.7% in 2017, representing a 30% increase over the decade. The proportion of OI/IUI births remained stable at around 2% of all births, representing 32% of all MAR births. Over the study period, ART births conceived by frozen embryo-transfer increased nearly 3-fold. OI/IUI births conceived using clomiphene citrate decreased by 39%, while OI/IUI births conceived using letrozole increased 56-fold. Overall, there was a 55% increase over the study period in the number of ART-conceived births, rising to 56% of births to mothers aged 40 years and older. In 2017, almost one in six births (17.6%) to mothers aged 40 years and over were conceived using ART treatment. Conversely, the proportion of OI/IUI births was similar across different mother’s age groups and remained stable over the study period. ART children, but not OI/IUI children, were more likely to have parents who were socio-economically advantaged compared to naturally conceived children. For example, compared to naturally conceived births, ART births were 16% less likely to be born to mothers who live in the disadvantaged neighbourhoods after accounting for other covariates (adjusted relative risk (aRR): 0.84 [95% CI: 0.81–0.88]). ART- or OI/IUI-conceived children were 25% less likely to be born to immigrant mothers than births after natural conception (aRR: 0.75 [0.74–0.77]).
LIMITATIONS, REASONS FOR CAUTION
The social inequalities that we observed between the parents of children born using ART and naturally conceived children may not directly reflect disparities in accessing fertility care for individuals seeking treatment.
WIDER IMPLICATIONS OF THE FINDINGS
With the ubiquitous decline in fertility rates around the world and the increasing trend to delay childbearing, this population-based study enhances our understanding of the contribution of different types of MARs to population profiles among births in high-income countries. The parental socio-demographic characteristics of MAR-conceived children differ significantly from naturally conceived children and this highlights the importance of accounting for such differences in studies investigating the health and development of MAR-conceived children.

Abstract
BACKGROUND Women tend to discontinue antidepressants during pregnancy. We examined the rate of and factors associated with antidepressant discontinuation and re-initiation during pregnancy. METHODS We conducted a nationwide cohort study using Korea's healthcare database. The study cohort included women who were aged 15-50 years, gave birth during 2013-2017, had ≥1 depression diagnosis, ≥2 antidepressant prescriptions within 6 months (one within one month of preconception). Cox proportional hazards model was used to evaluate factors associated with antidepressant discontinuation and re-initiation during pregnancy. RESULTS Among 5207 pregnancies, 4954 (95.1%) discontinued antidepressants during pregnancy, which included 4657 (89.4%) in the first trimester, 1810 (38.9%) of whom re-initiated them during pregnancy or postpartum period. The risk of antidepressant discontinuation increased in women with substance-related disorders (HR 1.17, 95% CI 1.01-1.35), but decreased in women receiving medical aid (0.53, 0.46-0.62) and patients suggestive of severe depression, such as psychiatric comorbidities and long-term antidepressant use before pregnancy. Antidepressant re-initiation occurred frequently in medical aid recipients (1.25, 1.06-1.47), nulliparous women (1.11, 1.01-1.22), and women with severe symptoms. CONCLUSIONS We found high rates of antidepressant discontinuation and re-initiation during pregnancy. Although women suggestive of severe symptoms were less likely to discontinue antidepressants during pregnancy, they were more likely to re-initiate them during their perinatal period, which warrants more detailed guidelines on perinatal depression.

Abstract
OBJECTIVE Hospital readmissions are generally higher among racial-ethnic minorities and patients of lower socioeconomic status. However, this has not been widely studied in obstetrics. The aim of the study is to determine 30-day postpartum readmission rates by patient-level social determinants of health: race ethnicity, primary insurance payer, and median income, independently and as effect modifiers. STUDY DESIGN Using state inpatient databases from the health care cost and utilization project from 2007 to 2014, we queried all deliveries. To produce accurate estimates of the effects of parturients' social determinants of health on readmission odds while controlling for confounders, generalized linear mixed models (GLMMs) were used. Additional models were generated with interaction terms to highlight any associations and their effect on the outcome. Adjusted odds ratios (aOR) with 95% confidence intervals are reported. RESULTS There were 5,129,867 deliveries with 79,260 (1.5%) 30-day readmissions. Of these, 947 (1.2%) were missing race ethnicity. Black and Hispanic patients were more likely to be readmitted within 30 days of delivery, as compared with White patients (p < 0.001 and p < 0.05, respectively). Patients with government insurance were more likely to be readmitted than those with private insurance (p < 0.001). Patients living in the second quartile of median income were also more likely to be readmitted than those living in other quartiles (p < 0.05). Using GLMMs, we observed that Black patients with Medicare were significantly more likely to get readmitted as compared with White patients with private insurance (aOR 2.78, 95% CI 2.50-3.09, p < 0.001). Similarly, Black patients living in the fourth (richest) quartile of median income were more likely to get readmitted, even when compared with White patients living in the first (poorest) quartile of median income (aOR 1.48, 95% CI 1.40-1.57, p < 0.001). CONCLUSION Significant racial-ethnic disparities in obstetric readmissions were observed, particularly in Black patients with government insurance and even in Black patients living in the richest quartile of median income. KEY POINTS · Using generalized linear mixed models, we observed significant interactions.. · Government-insured Black patients were 2.78X more likely to be readmitted.. · The wealthiest Black patients were still 1.48X more likely to be readmitted..

Abstract
Background: A comorbidity summary score may support early and systematic identification of women at high risk for adverse obstetric outcomes. The objective of this study was to conduct the initial development and validation of an obstetrics comorbidity risk score for automated implementation in the electronic health record (EHR) for clinical use. Methods: The score was developed and validated using EHR data for a retrospective cohort of pregnancies with delivery between 2010 and 2018 at Kaiser Permanente Northern California, an integrated health care system. The outcome used for model development consisted of adverse obstetric events from delivery hospitalization (e.g., eclampsia, hemorrhage, death). Candidate predictors included maternal age, parity, multiple gestation, and any maternal diagnoses assigned in health care encounters in the 12 months before admission for delivery. We used penalized regression for variable selection, logistic regression to fit the model, and internal validation for model evaluation. We also evaluated prenatal model performance at 18 weeks of pregnancy. Results: The development cohort (n = 227,405 pregnancies) had an outcome rate of 3.8% and the validation cohort (n = 41,683) had an outcome rate of 2.9%. Of 276 candidate predictors, 37 were included in the final model. The final model had a validation c-statistic of 0.72 (95% confidence interval [CI] 0.70-0.73). When evaluated at 18 weeks of pregnancy, discrimination was modestly diminished (c-statistic 0.68 [95% CI 0.67-0.70]). Conclusions: The obstetric comorbidity score demonstrated good discrimination for adverse obstetric outcomes. After additional appropriate validation, the score can be automated in the EHR to support early identification of high-risk women and assist efforts to ensure risk-appropriate maternal care.

Abstract
OBJECTIVE We sought to develop a prediction model using prenatal diagnosis codes that could help clinicians objectively stratify a women's risk for delivery-related morbidity. STUDY DESIGN We performed a prospective cohort study of women delivering at a single academic medical center between 2016 and 2019. Diagnosis codes from outpatient encounters were extracted from the electronic health record. Standard and common machine-learning methods for variable selection were compared. The performance characteristics from the selected model in the training data set-a LASSO model with a lambda that minimized the Bayes information criteria-were compared in a testing and external validation set. RESULTS The model identified a group of women, those in the highest decile of predicted risk, who were at a two to threefold increased risk of maternal morbidity. CONCLUSION As EHR data becomes more ubiquitous, other data types generated from the prenatal period may improve the model's performance.

[PMID: 34615477 PMCID: PMC8496026 DOI: 10.1186/s12884-021-04132-6] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2021] [Accepted: 09/16/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Improvement in the prediction and prevention of severe maternal morbidity (SMM) - a range of life-threatening conditions during pregnancy, at delivery or within 42 days postpartum - is a public health priority. Reduction of SMM at a population level would be facilitated by early identification and prediction. We sought to develop and internally validate a model to predict maternal end-organ injury or death using variables routinely collected during pre-pregnancy and the early pregnancy period. METHODS We performed a population-based cohort study using linked administrative health data in Ontario, Canada, from April 1, 2006 to March 31, 2014. We included women aged 18-60 years with a livebirth or stillbirth, of which one birth was randomly selected per woman. We constructed a clinical prediction model for the primary composite outcome of any maternal end-organ injury or death, arising between 20 weeks' gestation and 42 days after the birth hospital discharge date. Our model included variables collected from 12 months before estimated conception until 19 weeks' gestation. We developed a separate model for parous women to allow for the inclusion of factors from previous pregnancy(ies). RESULTS Of 634,290 women, 1969 experienced the primary composite outcome (3.1 per 1000). Predictive factors in the main model included maternal world region of origin, chronic medical conditions, parity, and obstetrical/perinatal issues - with moderate model discrimination (C-statistic 0.68, 95% CI 0.66-0.69). Among 333,435 parous women, the C-statistic was 0.71 (0.69-0.73) in the model using variables from the current (index) pregnancy as well as pre-pregnancy predictors and variables from any previous pregnancy. CONCLUSIONS A combination of factors ascertained early in pregnancy through a basic medical history help to identify women at risk for severe morbidity, who may benefit from targeted preventive and surveillance strategies including appropriate specialty-based antenatal care pathways. Further refinement and external validation of this model are warranted and can support evidence-based improvements in clinical practice.

Abstract
Reducing the rate of cesarean sections among women considered at low risk for delivery by that method is a goal of Healthy People 2030. Prior research suggests that perinatal mood and anxiety disorders increase the risk for cesarean section, but data are limited. This cross-sectional study of commercially insured women examined the relationship between perinatal depression and anxiety disorders and primary (first-time) cesarean section rates, using administrative claims data for US in-hospital deliveries from the period 2008-17. Of the 360,225 delivery hospitalizations among 317,802 unique women, 24.0 percent included a delivery by primary cesarean section, and 3.1 percent carried a diagnosis of depression, anxiety, or both made during the index pregnancy. Using an adjusted generalized estimating equation, we found that the predicted probability of primary cesarean section was 3.5 percentage points higher, on average, among women with these disorders compared with those without them. Our findings confirm the importance of pursuing research to identify mechanisms by which perinatal depression and anxiety disorders increase the risk for primary caesarean section among women otherwise considered at low risk for delivery by that method, as well as effective interventions.

Abstract
OBJECTIVE This study aimed to evaluate the performance of the California Maternal Quality Care Collaborative (CMQCC) admission risk criteria for stratifying postpartum hemorrhage risk in a large obstetrics population. STUDY DESIGN Using detailed electronic health record data, we classified 261,964 delivery hospitalizations from Kaiser Permanente Northern California hospitals between 2010 and 2017 into high-, medium-, and low-risk groups based on CMQCC criteria. We used logistic regression to assess associations between CMQCC risk groups and postpartum hemorrhage using two different postpartum hemorrhage definitions, standard postpartum hemorrhage (blood loss ≥1,000 mL) and severe postpartum hemorrhage (based on transfusion, laboratory, and blood loss data). Among the low-risk group, we also evaluated associations between additional present-on-admission factors and severe postpartum hemorrhage. RESULTS Using the standard definition, postpartum hemorrhage occurred in approximately 5% of hospitalizations (n = 13,479), with a rate of 3.2, 10.5, and 10.2% in the low-, medium-, and high-risk groups. Severe postpartum hemorrhage occurred in 824 hospitalizations (0.3%), with a rate of 0.2, 0.5, and 1.3% in the low-, medium-, and high-risk groups. For either definition, the odds of postpartum hemorrhage were significantly higher in medium- and high-risk groups compared with the low-risk group. Over 40% of postpartum hemorrhages occurred in hospitalizations that were classified as low risk. Among the low-risk group, risk factors including hypertension and diabetes were associated with higher odds of severe postpartum hemorrhage. CONCLUSION We found that the CMQCC admission risk assessment criteria stratified women by increasing rates of severe postpartum hemorrhage in our sample, which enables early preparation for many postpartum hemorrhages. However, the CMQCC risk factors missed a substantial proportion of postpartum hemorrhages. Efforts to improve postpartum hemorrhage risk assessment using present-on-admission risk factors should consider inclusion of other nonobstetrical factors.

Cesarean Deliveries Among Immigrant and Canadian-Born Women in a Representative Community Population in Canada: A Retrospective Cohort Study. JOURNAL OF OBSTETRICS AND GYNAECOLOGY CANADA 2021; 44:148-156.

Abstract
OBJECTIVE To examine differences in the rate of cesarean delivery between Canadian-born women and immigrants to Canada and by duration of time in Canada and rate of cesarean delivery in their country-of-origin. METHODS We used linked data from hospitalization records and the Canadian Community Health Survey for all deliveries after 20 weeks gestation between 2002 and 2017 in Canada (excluding Québec). Odds of cesarean delivery in recent immigrants (<5 y in Canada) and non-recent immigrants (≥5 y in Canada) were compared with those of Canadian-born women using multivariable logistic regression. Immigrants were further categorized using the cesarean delivery rate in their country-of-origin as low (<10%), medium (≥10 to <35%), or high (≥35%). RESULTS Of the 53 505 women included, 89% were Canadian-born, 4% were recent immigrants and 7% were non-recent immigrants. Overall, 28.6% of women had a cesarean delivery. After adjusting for medical and socio-economic factors, the odds of cesarean delivery among recent immigrants (OR 1.12; 95% CI 0.95-1.34) and non-recent immigrants (OR 1.11; 95% CI 0.98-1.25) did not differ statistically from those of Canadian-born women. Recent immigrants from countries with lower caesarean delivery rates had higher odds of cesarean delivery (OR 1.34; 95% CI 1.05-1.70), whereas the odds of caesarean for recent immigrants from medium- and high-rate countries did not differ from those of Canadian-born women. CONCLUSION After accounting for demographic and medical factors, few differences remained in cesarean delivery rates between immigrants and Canadian-born women. Country-of-origin practices are unlikely to reflect preferences for cesarean delivery in immigrant women in Canada.

The Comparative Effectiveness of Varenicline and Nicotine Patches for Smoking Abstinence During Pregnancy: Evidence From a Population-based Cohort Study. Nicotine Tob Res 2021; 23:1664-1672.

Abstract
INTRODUCTION In the general population, varenicline is consistently shown to be more efficacious for smoking cessation than nicotine replacement therapy (NRT). Current clinical guidelines for the management of smoking during pregnancy recommend against the use of varenicline, whilst supporting the use of NRT. However, little is known about the comparative effectiveness of these smoking cessation therapies among pregnant women. AIMS AND METHODS Routinely-collected records of all births in two Australian States during 2011 and 2012 were used to create a population-based cohort of women who smoked during the first half of pregnancy. Pharmaceutical dispensing data were used to identify varenicline and nicotine patch dispensings in the first half of pregnancy. Propensity score matching was used to account for the potentially different distribution of confounding factors between the treatment groups. The outcome was defined as smoking abstinence during the second half of pregnancy. RESULTS After propensity score-matching, our cohort comprised 60 women who used varenicline and 60 who used nicotine patches during the first half of pregnancy. More varenicline users (33.3%, 95% CI: 21.7%-46.7%) quit smoking than nicotine patch users (13.3%, 95% CI: 5.9%-24.6%). The adjusted rate difference was 24.2% (95% CI: 10.2%-38.2%) and the adjusted relative risk was 2.8 (95% CI: 1.4-5.7). CONCLUSIONS Varenicline was almost three times more effective than nicotine patches in assisting pregnant women to quit smoking. Further studies are needed to corroborate our results. Together with data on the safety of varenicline during pregnancy, evidence regarding the relative benefit of varenicline and NRT during pregnancy important for informing clinical decisions for pregnant smokers. IMPLICATIONS This study is the first to measure the comparative effectiveness of varenicline and nicotine patches during pregnancy - women using varenicline were almost three times as likely to quit smoking than those using nicotine patches. This study addressed a clinically important question using an observational study, noting that there is an absence of evidence from randomized controlled trials because of the ethical issues associated with including pregnant women in clinical trials of medicines of unknown safety.

Racial and Ethnic Disparities in Death Associated With Severe Maternal Morbidity in the United States: Failure to Rescue. Obstet Gynecol 2021; 137:791-800.

Abstract
OBJECTIVE To analyze racial and ethnic disparities in failure to rescue (ie, death) associated with severe maternal morbidity and describe temporal trends. METHODS This was a retrospective cohort study using administrative data. Data for delivery hospitalizations with severe maternal morbidity, as defined by the Centers for Disease Control and Prevention, were abstracted from the 1999-2017 National Inpatient Sample. Race and ethnicity were categorized into non-Hispanic White (reference), non-Hispanic Black, Hispanic, other, and missing. The outcome was failure to rescue from severe maternal morbidity. Disparities were assessed using the failure-to-rescue rate ratio (ratio of the failure-to-rescue rate in the racial and minority group to the failure-to-rescue rate in White women), adjusted for patient and hospital characteristics. Temporal trends in severe maternal morbidity and failure to rescue were assessed. RESULTS During the study period, 73,934,559 delivery hospitalizations were identified, including 993,864 with severe maternal morbidity (13.4/1,000; 95% CI 13.3-13.5). Among women with severe maternal morbidity, 4,328 died (4.3/1,000; 95% CI 4.2-4.5). The adjusted failure-to-rescue rate ratio was 1.79 (95% CI 1.77-1.81) for Black women, 1.39 (95% CI 1.37-1.41) for women of other race and ethnicity, 1.43 (95% CI 1.42-1.45) for women with missing race and ethnicity data, and 1.08 (95% CI 1.06-1.09) for Hispanic women. During the study period, the severe maternal morbidity rate increased significantly in each of the five racial and ethnic groups but started declining in 2012. Meanwhile, the failure-to-rescue rate decreased significantly during the entire study period. CONCLUSION Despite improvement over time, failure to rescue from severe maternal morbidity remains a major contributing factor to excess maternal mortality in racial and ethnic minority women.

Abstract
Introduction Designated high-quality trauma services have been shown to improve outcomes of trauma patients by virtue of access to specialized personnel and resources. It remains unclear if a ‘halo effect’ extends these benefits more generally to non-trauma populations. Obstetric patients who develop severe postpartum hemorrhage often require close attention in intensive care units and utilize more resources. Given the overlapping needs between trauma and obstetric patients, we hypothesize that the ‘halo effect’ might extend to patients with severe postpartum hemorrhage. Methods The Nationwide Inpatient Sample for years 2008 to 2011 was queried. Patients with severe postpartum hemorrhage were identified as those requiring transfusion, hysterectomy, or uterine repair. After stratifying by level 1 trauma center versus non-level 1 trauma center status, unadjusted univariate comparisons were made. Adjusted odds ratio of end-organ failure and death were analyzed using multivariable logistic regression. Results A total of 11,135 patients were identified with severe postpartum hemorrhage. The majority were hospitalized at non-level 1 trauma centers rather than level 1 trauma centers (71.4% vs. 28.6%). Patients at non-level 1 trauma centers were younger, more likely to be white, admitted electively, insured, and healthier with a lower comorbidity index. There was no significant difference in rates of mortality or organ failure. However, after adjustment for differences in comorbidity index, race, and emergency admission, patients at non-level 1 trauma centers had a significantly higher risk of respiratory failure (odds ratio, 1.27; 95% confidence interval, 1.01–1.59). Conclusions These findings suggest that the outcomes of obstetric patients with severe postpartum hemorrhage admitted in level 1 trauma centers are not overall significantly different when compared to those in non-level 1 trauma centers. However, after adjusting for baseline characteristics, there was a reduced risk of respiratory failure in patients admitted to level 1 trauma centers.

Abstract
BACKGROUND Black-serving hospitals are associated with increased maternal risk. However, prior administrative data research on maternal disparities has generally included limited hospital factors. More detailed evaluation of hospital factors related to obstetric outcomes may be important in understanding disparities. OBJECTIVE To examine detailed characteristics of Black-serving hospitals and how these characteristics are associated with risk for severe maternal morbidity (SMM). METHODS This serial cross-sectional study linked the 2010-2011 Nationwide Inpatient Sample and the 2013 American Hospital Association Annual Survey Databases. Delivery hospitalizations occurring to women 15-54 years of age were identified. The proportions of non-Hispanic Black patients within a hospital was categorized into quartiles, and hospital factors such as specialized medical, surgical and safety-net services as well as payer mix were compared across these quartiles. A series of models was performed evaluating risk for SMM with Black-serving hospital quartile as the primary exposure. Log linear regression models with a Poisson distribution (and robust variance) were performed with unadjusted and adjusted risk ratios (aRR) with 95% confidence intervals (CIs) as measures of effect. RESULTS Overall 965,202 deliveries from 430 hospitals met inclusion criteria and were included in the analysis. By quartile, non-Hispanic Black patients accounted for 1.3%, 5.4%, 13.4%, and 33.8% of patients. Many services were significantly less common in the lowest compared to the highest Black-serving hospital quartile including cardiac intensive care (48.9% versus 74.5%), neonatal intensive care (28.9% versus 64.9%), pediatric intensive care (20.0% versus 45.7%), pediatric cardiology (29.6% versus 44.7%), and HIV/AIDS services (36.3% versus 71.3%) (p≤0.01 for all). Indigent care clinics, crisis prevention, and enabling services (p≤0.01 for all) were more common at Black-serving hospitals as was Medicaid payer. Following adjustments for detailed hospital factors, the lowest Black serving hospital quartile carried the lowest risk for SMM. However, SMM risks were similar across the 2nd (aRR 1.31, 95% CI 1.08, 1.59), 3rd (aRR 1.27, 95% 1.05, 1.55), and 4th (aRR 1.29, 95% CI 1.07, 1.55) quartiles. CONCLUSION Black-serving hospitals were more likely to provide a range of specialized medical, surgical, and safety-net services and to have a higher Medicaid burden. Payer mix and unmeasured confounding may account for some of the maternal risk associated with Black-serving hospitals.

Abstract
OBJECTIVE To determine whether adjusting for healthcare utilization and comorbidity diagnosed in the year before delivery improves the prediction of adverse maternal outcomes. METHODS The Truven Health MarketScan database was used to determine whether healthcare utilization and comorbidity diagnosed in the year before pregnancy improved prediction of acute organ injury or death during the delivery hospitalization through 30 days postpartum in this retrospective cohort study. In an initial model, we analyzed the risk for adverse outcomes controlling for underlying comorbidity, obesity, and demographic risk factors present during pregnancy. Subsequent models included diagnoses from the year before pregnancy as well as whether patients had emergency department encounters, inpatient hospitalizations, or received medications from a pharmacy. We compared risk estimates and whether prediction of acute organ injury or death improved with data from the year before pregnancy. Unadjusted and adjusted log-linear regression models were performed to demonstrate the association between exposures and outcomes with unadjusted (RR) and adjusted risk ratios (aRR) with 95% CIs as measures of effects. Logistic regression was performed to calculate the c-statistic of the adjusted models. Separate analyses were performed for patients with Medicaid and commercial insurance. An analysis of Medicaid patients by maternal race and ethnicity was performed to determine if diagnoses and utilization before pregnancy accounted for maternal disparities. RESULTS A total of 740,002 patients were analyzed in this study. In unadjusted analyses of patients with commercial insurance, ≥2 compared to 0 emergency department encounters (RR = 1.82, 95% CI = 1.61, 2.07), ≥2 compared to 0 inpatient hospitalizations (RR = 4.43, 95% CI = 3.20, 6.13), and receipt of medications from ≥5 prescription groups compared to no prescriptions (RR = 1.97, 95% CI = 1.74, 2.24) were all associated with increased risk for acute organ injury or death. Higher underlying comorbidity and obesity were also associated with increased risk. These risks were attenuated in adjusted analyses but retained significance. Risk estimates were similar for patients with Medicaid insurance with the exception of receipt of medications from ≥5 prescription groups which was non-significant in adjusted analyses (aRR = 1.12, 95% CI = 0.90, 1.40). C-statistics from logistic regression models were similar for models with and without pre-pregnancy data. When race was added to the adjusted models, risk among black women in the adjusted models did not differ significantly from the unadjusted estimate. CONCLUSION ED encounters and inpatient admissions the year before pregnancy were associated with increased risk of adverse maternal outcomes. However, adding these risk factors to adjusted models did not meaningfully improve the amount of variance accounted for. Further research is indicated to determine to what degree longitudinal care quality is associated with maternal risk.

Abstract
BACKGROUND High Black-serving delivery units and high hospital safety-net burden have been associated with poorer patient outcomes. We examine these hospital-level factors and their association with severe maternal morbidity (SMM), independently and as effect modifiers of patient-level factors. METHODS Using the 2007-2014 State Inpatient Databases (Florida, New York, California, Maryland, Kentucky), we analyzed delivery hospitalizations. We constructed generalized linear mixed models with patient- and hospital-level variables (Black-serving delivery units: high: top 5th percentile; medium: 5th-25th percentile; low: bottom 75th percentile; hospital safety-net burden status defined by insurance status) and report adjusted odds ratios (aOR) and 99% confidence intervals (CI). We repeated our mixed models with stratification and interaction analysis. RESULTS 6 879 332 delivery hospitalizations were included in the analysis. Deliveries at high (aOR 1.83; 99% CI 1.34 to2.50) or medium (aOR 1.27; 99% CI 1.10 to 1.46) Black-serving delivery units were more likely to have SMM than deliveries at low Black-serving delivery units. Hospital safety-net burden was not significantly associated with SMM. In stratified models by hospital category, deliveries of Black women were associated with an increase in SMM compared with deliveries of White women in all hospital categories. In interaction models, Black women giving birth in high Black-serving delivery units had more than twice the odds of White women in low Black-serving delivery units of experiencing SMM (aOR 2.42; 99% CI 1.90 to 3.08). CONCLUSION The patient racial/ethnic composition of the delivery unit is associated with adjusted-odds of SMM, both independently and interactively with individual patient race.

Abstract
The rates of maternal morbidity and mortality in the United States demand a comprehensive approach to assessing pregnancy-related risks. Numerous medical and nonmedical factors contribute to maternal morbidity and mortality. Reducing the number of women who experience pregnancy morbidity requires identifying which women are at greatest risk and initiating appropriate interventions early in the reproductive life course. The purpose of this Consult is to educate all healthcare practitioners about factors contributing to a high-risk pregnancy, strategies to assess maternal health risks due to pregnancy, and the importance of risk assessment across the reproductive spectrum in reducing maternal morbidity and mortality.

Abstract
Background In June 2013, the city of Calgary, Alberta and surrounding areas sustained significant flooding which resulted in large scale evacuations and closure of businesses and schools. Floods can increase stress which may negatively impact perinatal outcomes and mental health, but previous research is inconsistent. The objectives of this study are to examine the impact of the flood on pregnancy health, birth outcomes and postpartum mental health. Methods Linked administrative data from the province of Alberta were used. Outcomes included preterm birth, small for gestational age, a new diagnoses of preeclampsia or gestational hypertension, and a diagnosis of, or drug prescription for, depression or anxiety. Data were analyzed using a quasi-experimental difference in difference design, comparing flooded and non-flooded areas and in affected and unaffected time periods. Multivariable log binomial regression models were used to estimate risk ratios, adjusted for maternal age. Marginal probabilities for the difference in difference term were used to show the potential effect of the flood. Results Participants included 18,266 nulliparous women for the pregnancy outcomes, and 26,956 women with infants for the mental health analysis. There were no effects for preterm birth (DID 0.00, CI: -0.02, 0.02), small for gestational age (DID 0.00, CI: -0.02, 0.02), or new cases of preeclampsia (DID 0.00, CI: -0.01, 0.01). There was a small increase in new cases of gestational hypertension (DID 0.02, CI: 0.01, 0.03) in flood affected areas. There were no differences in postpartum anxiety or depression prescriptions or diagnoses. Conclusion The Calgary 2013 flood was associated with a minor increase in gestational hypertension and not other health outcomes. Universal prenatal care and magnitude of the disaster may have minimized impacts of the flood on pregnant women.

Abstract
OBJECTIVE To evaluate the risk of first trimester exposure to prescription opioids for major congenital malformations, previously reported to be associated with such exposure. DESIGN Population based cohort study. SETTING Nationwide sample of publicly and commercially insured pregnant women linked to their liveborn infants, nested in the Medicaid Analytic eXtract (MAX, 2000-14) and the MarketScan Research Database (MarketScan, 2003-15). PARTICIPANTS 1 602 580 publicly insured (MAX) and 1 177 676 commercially insured (MarketScan) pregnant women with eligibility from at least three months before pregnancy to one month after delivery; infants with eligibility for at least three months after birth. INTERVENTIONS Use of prescription opioids was ascertained by requiring two or more dispensations of any opioid during the first trimester. MAIN OUTCOMES MEASURES Major malformations overall, cardiac malformations overall, ventricular septal defect, secundum atrial septal defect/patent foramen ovale, neural tube defect, clubfoot, and oral cleft, defined based on validated algorithms. Propensity score stratification was used to adjust for potential confounders and/or proxies for confounders. Estimates from each database were combined using meta-analysis. RESULTS 70 447 (4.4%) of 1 602 580 publicly insured and 12 454 (1.1%) of 1 177 676 commercially insured pregnant women had two or more dispensations of an opioid during the first trimester. Absolute risk of malformations overall was 41.0 (95% confidence interval 39.5 to 42.5) per 1000 pregnancies exposed to opioids versus 32.0 (31.7 to 32.3) per 1000 unexposed pregnancies in the MAX cohort, and 42.6 (39.0 to 46.1) and 37.3 (37.0 to 37.7) per 1000, respectively, in the MarketScan cohort. Pooled unadjusted relative risk estimates were raised for all outcomes but shifted substantially toward the null after adjustment; for malformations overall (relative risk 1.06, 95% confidence interval 1.02 to 1.10), cardiovascular malformations (1.09, 1.00 to 1.18), ventricular septal defect (1.07, 0.95 to 1.21), atrial septal defect/patent foramen ovale (1.04, 0.88 to 1.24), neural tube defect (0.82, 0.53 to 1.27), and clubfoot (1.06, 0.88 to 1.28). The relative risk for oral clefts remained raised after adjustment (1.21, 0.98 to 1.50), with a higher risk of cleft palate (1.62, 1.23 to 2.14). CONCLUSIONS Prescription opioids used in early pregnancy are not associated with a substantial increase in risk for most of the malformation types considered, although a small increase in the risk of oral clefts associated with their use is possible.

Abstract
INTRODUCTION Women with gestational diabetes are 7 times more likely to develop type 2 diabetes and require lifelong diabetes screening. Loss of health coverage after pregnancy, as occurs in states that did not expand Medicaid, limits access to guideline-driven follow-up care and fosters health inequity. This study aims to understand the factors associated with the receipt of postpartum diabetes screening for women with gestational diabetes in a state without Medicaid expansion. METHODS Electronic health record and Medicaid claims data were linked to generate a retrospective cohort of 1,078 women with gestational diabetes receiving care in Federally Qualified Health Centers in Missouri from 2010 to 2015. In 2019-2020, data were analyzed to determine the factors associated with the receipt of recommended postpartum diabetes screening (fasting plasma glucose, 2-hour oral glucose tolerance test, or HbA1c in specified timeframes) using a Cox proportional hazards model through 18 months of follow-up. RESULTS Median age in this predominantly urban population was 28 (IQR=24-33) years. Self-reported racial or ethnic minorities comprised more than half of the population. Only 9.7% of women were screened at 12 weeks, and 20.8% were screened at 18 months. Prenatal certified diabetes education (adjusted hazard ratio=1.74, 95% CI=1.22, 2.49) and access to public transportation (adjusted hazard ratio=1.70, 95% CI=1.13, 2.54) were associated with increased screening in a model adjusted for race/ethnicity, the total number of prenatal visits, the use of diabetes medication during pregnancy, and a pregnancy-specific comorbidity index that incorporated age. CONCLUSIONS This study underscores the importance of access to public transportation, prenatal diabetes education, and continued healthcare coverage for women on Medicaid to support the receipt of guideline-recommended follow-up care and improve health equity.

Abstract
BACKGROUND Labor neuraxial analgesia utilization has increased in the United States (U.S.) but its impact on maternal safety is unknown. This study analyzed the temporal trends in the incidence of post-dural puncture headache (PDPH) in obstetrics. METHODS Data for vaginal or intrapartum cesarean deliveries came from the National Inpatient Sample 2006-2015, a U.S. 20% representative sample of hospital discharge records. The outcome was PDPH (ICD-9-CM codes 349.0 and 03.95) categorized into (1) PDPH coded without epidural blood patch (EBP), and (2) PDPH coded with EBP. Temporal trends in incidence were described using the percent change between 2006 and 2015 and its 95% confidence interval (CI). RESULTS Of the 29 011 472 deliveries studied, 86 558 (29.8 per 10 000; 95% CI: 29.3 to 30.2) recorded a diagnosis of PDPH, including 34 019 without EBP (11.7 per 10 000; 95% CI 11.4 to 12.0) and 52 539 with EBP (18.1 per 10 000; 95% CI 17.8 to 18.4). A significant decrease in the incidence of PDPH was observed from 31.5 per 10 000 in 2006 to 29.2 per 10 000 in 2015 (-7.5%; 95% CI -2.2 to -0.5; P=0.001). The decrease in the incidence of PDPH was significant irrespective of the presence of EBP. The decrease was observed in the three categories of hospitals examined (rural, urban non-teaching, and urban teaching). CONCLUSIONS During the study period, the reported incidence of PDPH in the U.S. has decreased modestly. Intervention programs are needed to address this persistent and preventable cause of maternal morbidity.

Abstract
BACKGROUND Medicaid expansions under the Affordable Care Act have increased insurance coverage and prenatal care utilization in low-income women. However, it is not clear whether they are associated with any measurable improvement in maternal health outcomes. In this study, we compared the changes in the incidence of severe maternal morbidity (SMM) during delivery hospitalizations between low- and high-income women associated with the 2014 Medicaid expansion in New York State. METHODS Data for this retrospective cohort study came from the 2006-2016 New York State Inpatient Database, a census of discharge records from community hospitals. The outcome was SMM during delivery hospitalizations, as defined by the Centers for Disease Control and Prevention. We used regression coefficients (β) from multivariable logistic models: (1) to compare independently in low-income women and in high-income women the changes in slopes in the incidence of SMM before (2006-2013) and after (2014-2016) the expansion, and (2) to compare low- and high-income women for the changes in slopes in the incidence of SMM before and after the expansion. RESULTS A total of 2,286,975 delivery hospitalizations were analyzed. The proportion of Medicaid beneficiaries in parturients increased a relative 12.1% (95% confidence interval [CI], 11.8-12.4), from 42.9% in the preexpansion period to 48.1% in the postexpansion period, whereas the proportion of the uninsured decreased a relative 4.8% (95% CI, 2.8-6.8). Multivariable logistic modeling revealed that implementation of the 2014 Medicaid expansion was associated with a decreased slope during the postexpansion period both in low-income women (β = -0.0161 or 1.6% decrease; 95% CI, -0.0190 to -0.0132) and in high-income women (β = -0.0111 or 1.1% decrease; 95% CI, -0.0130 to -0.0091). The decrease in slope during the postexpansion period was greater in low- than in high-income women (β = -0.0042 or 0.42% difference; 95% CI, -0.0076 to -0.0007). CONCLUSIONS Implementation of the Medicaid expansion in 2014 in New York State is associated with a small but statistically significant reduction in the incidence of SMM in low-income women compared with high-income women.

Abstract
Background The early identification of pregnant women at risk of developing complications at birth is fundamental to antenatal care and an important strategy in preventing maternal death. This study aimed to determine the prevalence of high-risk pregnancies and explore the association between risk stratification and severe maternal morbidity. Methods This hospital-based prospective cohort study included 346 pregnant women between 28–32 gestational weeks who were followed up after childbirth at Koshi Hospital in Nepal. The Malaysian antenatal risk stratification approach, which applies four color codes, was used: red and yellow denote high-risk women, while green and white indicate low-risk women based on maternal past and present medical and obstetric risk factors. The World Health Organization criteria were used to identify women with severe maternal morbidity. Multivariate confirmatory logistic regression analysis was performed to adjust for possible confounders (age and mode of birth) and explore the association between risk stratification and severe maternal morbidity. Results The prevalence of high-risk pregnancies was 14.4%. Based on the color-coded risk stratification, 7.5% of the women were categorized red, 6.9% yellow, 72.0% green, and 13.6% white. The women with high-risk pregnancies were 4.2 times more likely to develop severe maternal morbidity conditions during childbirth. Conclusions Although smaller in percentage, the chances of severe maternal morbidity among high-risk pregnancies were higher than those of low-risk pregnancies. This risk scoring approach shows the potential to predict severe maternal morbidity if routine screening is implemented at antenatal care services. Notwithstanding, unpredictable severe maternal morbidity events also occur among low-risk pregnant women, thus all pregnant women require vigilance and quality obstetrics care but high-risk pregnant women require specialized care and referral.

Abstract
BACKGROUND Rates of maternal mortality and severe maternal morbidity (SMM) are higher in the United States than in other high-resource countries and are increasing further. OBJECTIVE To examine the association of maternal comorbid conditions, age, body mass index, and previous cesarean birth with occurrence of SMM. DESIGN Population-based cohort study using linked delivery hospitalization discharge data and vital records. SETTING California, 1997 to 2014. PATIENTS All 9 179 472 mothers delivering in California during 1997 to 2014. MEASUREMENTS SMM rate, total and without transfusion-only cases; 2019 maternal comorbidity index. RESULTS Total SMM increased by 160% during this time, and SMM excluding transfusion-only cases increased by 53%. Medical comorbid conditions were associated with an increasing portion of SMM occurrences. Medical comorbid conditions increased over the study period by 111%, and obstetric comorbid conditions increased by 30% to 40%. Identified medical comorbid conditions had high relative risks ranging from 1.3 to 14.3 for total SMM and even higher relative risks for nontransfusion SMM (to 32.4). The obstetric comorbidity index that is most often used may be undervaluing the degree of association with SMM. LIMITATIONS Hospital discharge diagnosis files and birth certificate records can have misclassifications and may not include all relevant clinical data or social determinants. The period for analysis ended in 2014 to avoid the transition to the International Classification of Diseases, 10th Revision, Clinical Modification, and therefore missed more recent years. CONCLUSION Obstetric and, particularly, medical comorbid conditions are increasing among women who develop SMM. The maternal comorbidity index is a promising tool for patient risk assessment and case-mix adjustment, but refinement of factor weights may be indicated.
