Abstract
Despite recent advances in surgical techniques and perinatal management in obstetrics for reducing intraoperative bleeding, blood transfusion may occur during a cesarean section (CS). This study aims to identify machine learning models with an optimal diagnostic performance for intraoperative transfusion prediction in parturients undergoing a CS. Additionally, to address model performance degradation due to data imbalance, this study further investigated the variation in predictive model performance depending on the ratio of event to non-event data (1:1, 1:2, 1:3, and 1:4 model datasets and raw data).The area under the receiver operating characteristic curve (AUROC) and area under the precision-recall curve (AUPRC) were evaluated to compare the predictive accuracy of different machine learning algorithms, including XGBoost, K-nearest neighbor, decision tree, support vector machine, multilayer perceptron, logistic regression, random forest, and deep neural network. We compared the predictive performance of eight prediction algorithms that were applied to five types of datasets. The intraoperative transfusion in maternal CS was 7.2% (1020/14,254). XGBoost showed the highest AUROC (0.8257) and AUPRC (0.4825) among the models. The most significant predictors for transfusion in maternal CS as per machine learning models were placenta previa totalis, haemoglobin, placenta previa partialis, and platelets. In all eight prediction algorithms, the change in predictive performance based on the AUROC and AUPRC according to the resampling ratio was insignificant. The XGBoost algorithm exhibited optimal performance for predicting intraoperative transfusion. Data balancing techniques employed to alter the event data composition ratio of the training data failed to improve the performance of the prediction model.

Interpretable machine learning predicts postpartum hemorrhage with severe maternal morbidity in a lower-risk laboring obstetric population. Am J Obstet Gynecol MFM 2024:101391. [PMID: 38851393 DOI: 10.1016/j.ajogmf.2024.101391] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2023] [Revised: 05/12/2024] [Accepted: 05/20/2024] [Indexed: 06/10/2024]
Abstract
BACKGROUND Early identification of patients at increased risk for postpartum hemorrhage (PPH) associated with severe maternal morbidity (SMM) is critical for preparation and preventative intervention. However, prediction is challenging in patients without obvious risk factors for postpartum hemorrhage with severe maternal morbidity. Current tools for hemorrhage risk assessment use lists of risk factors rather than predictive models. OBJECTIVE To develop, validate (internally and externally), and compare a machine learning model for predicting PPH associated with SMM against a standard hemorrhage risk assessment tool in a lower risk laboring obstetric population. STUDY DESIGN This retrospective cross-sectional study included clinical data from singleton, term births (>=37 weeks' gestation) at 19 US hospitals (2016-2021) using data from 58,023 births at 11 hospitals to train a generalized additive model (GAM) and 27,743 births at 8 held-out hospitals to externally validate the model. The outcome of interest was PPH with severe maternal morbidity (blood transfusion, hysterectomy, vascular embolization, intrauterine balloon tamponade, uterine artery ligation suture, uterine compression suture, or admission to intensive care). Cesarean birth without a trial of vaginal birth and patients with a history of cesarean were excluded. We compared the model performance to that of the California Maternal Quality Care Collaborative (CMQCC) Obstetric Hemorrhage Risk Factor Assessment Screen. RESULTS The GAM predicted PPH with an area under the receiver-operating characteristic curve (AUROC) of 0.67 (95% CI 0.64-0.68) on external validation, significantly outperforming the CMQCC risk screen AUROC of 0.52 (95% CI 0.50-0.53). Additionally, the GAM had better sensitivity of 36.9% (95% CI 33.01-41.02) than the CMQCC screen sensitivity of 20.30% (95% CI 17.40-22.52) at the CMQCC screen positive rate of 16.8%. The GAM identified in-vitro fertilization as a risk factor (adjusted OR 1.5; 95% CI 1.2-1.8) and nulliparous births as the highest PPH risk factor (adjusted OR 1.5; 95% CI 1.4-1.6). CONCLUSION Our model identified almost twice as many cases of PPH as the CMQCC rules-based approach for the same screen positive rate and identified in-vitro fertilization and first-time births as risk factors for PPH. Adopting predictive models over traditional screens can enhance PPH prediction.

Abstract
INTRODUCTION Red blood cell (RBC) transfusions are of utmost importance in the management of severe post-partum haemorrhage. Although the recommendations for blood transfusion protocols are regularly issued, there are significant differences in management depending on the context and the medical teams involved. OBJECTIVE To determine during the first 24 h, the clinical and biological factors associated with the decision for RBC transfusion during severe PPH (≥1000 mL) for vaginal and caesarean deliveries. STUDY DESIGN Monocentric retrospective study conducted in a tertiary care university maternity unit (CHI-Creteil) including all parturients from November 23th 2018 to 31th December 2020 with severe PPH (≥1000 mL). RESULTS Over the study period, we reported 7103 deliveries, out of which 682 were complicated by PPH (9.6 %) with 200 cases of PPH ≥1000 mL (2.8 %). In our study, 40 % of patients (80/200) required a RBC transfusion". After multivariate analysis, severe PPH caused by placental abruption, uterine rupture or placental implantation disorders (aOR = 3.48 IC95 [1.27-9.52], p < 0.001), estimated blood loss ≥1500 mL (aOR = 9.60 IC95 [3.69-24.95], p < 0. 001), invasive measures such as uterine balloon tamponade, arterial ligation and uterine packing (aOR = 4.15 IC95 [1.80-9.61], p < 0.001), pre-labor hemoglobin <10 g/dL (aOR =4.88 IC95 [1.57-15.15], p < 0.001) or abnormal biological results in the acute phase (including hemoglobin <7.0 g/dL and/or fibrinogen <2 g/L and/or platelets <100 G/L) (aOR =356 IC95 [1,05-12,10], p < 0.001) were significantly and independently associated with the decision to initiate RBC transfusions. CONCLUSIONS In a monocentric retrospective study including 200 consecutive cases of severe PPH (≥1000 mL) we identified groups of clinical and biological factors directly accessible to clinicians, significantly and independently associated with RBC transfusion in the first 24 h of management.

Report from a text-based blood pressure monitoring prospective cohort trial among postpartum women with hypertensive disorders of pregnancy. BMC Pregnancy Childbirth 2024; 24:340. [PMID: 38702619 PMCID: PMC11067202 DOI: 10.1186/s12884-024-06511-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2023] [Accepted: 04/11/2024] [Indexed: 05/06/2024] Open
Abstract
BACKGROUND Hypertensive disorders of pregnancy are a main cause of maternal morbidity and mortality in the United States and worldwide, and it is estimated that approximately 60% of maternal deaths in the United States occur during the postpartum period. The utilization of telehealth modalities such as home blood pressure monitoring has shown improvement in blood pressure control and adherence with follow up visits. Our study sought to determine if standardized education improved patient hypertension knowledge and if this when combined with home blood pressure telemonitoring increased participants' postpartum self-blood pressure monitoring and postpartum visit attendance. METHODS This is an Institutional Review Board approved prospective cohort study conducted at the University of Mississippi Medical Center. Women with a hypertensive disorder of pregnancy who met the inclusion criteria and provided written informed consent to participate were enrolled. Participants received a baseline pre-education questionnaire designed to assess their knowledge of their hypertensive diagnosis, hypertension management, and postpartum preeclampsia (PreE). Participants then received standard education, a blood pressure monitor, and were scheduled a follow-up visit during the first 10 days following discharge. Remote home blood pressure monitoring was performed via text messages and voice calls for 6-weeks postpartum. At the conclusion of the study, participants repeated their original questionnaire. RESULTS 250 women provided informed consent to participate in the study and were included in this analysis. Relative to the baseline survey, there was a significant increase (p = 0.0001) in the percentage of correct responses. There was not an association between study engagement and percentage of correct responses on end of study questionnaire (p = 0.33) or postpartum visit attendance (p = 0.69). Maternal age was found to drive study engagement, even when adjusted for community-level distress (p = 0.03) and maternal race (p = 0.0002). CONCLUSION Implementing a standardized postpartum education session was associated with improvement in patient's knowledge. Further studies are needed with more longitudinal follow up to assess if this program would also result in improved long-term outcomes and decreased hospital readmission rates. TRIAL REGISTRATION NCT04570124.

Abstract
OBJECTIVE We evaluated the associations of the obstetric comorbidity index (OB-CMI) and social vulnerability index (SVI) with severe maternal morbidity (SMM). STUDY DESIGN Multicenter retrospective cohort study of all patients who delivered (gestational age > 20 weeks) within a university health system from January 1, 2019, to December 31, 2021. OB-CMI scores were assigned to patients using clinical documentation and diagnosis codes. SVI scores, released by the Centers for Disease Control and Prevention (CDC), were assigned to patients based on census tracts. The primary outcome was SMM, based on the 21 CDC indicators. Mixed-effects logistic regression was used to model the odds of SMM as a function of OB-CMI and SVI while adjusting for maternal race and ethnicity, insurance type, preferred language, and parity. RESULTS In total, 73,518 deliveries were analyzed. The prevalence of SMM was 4% (n = 2,923). An association between OB-CMI and SMM was observed (p < 0.001), where OB-CMI score categories of 1, 2, 3, and ≥4 were associated with higher odds of SMM compared with an OB-CMI score category of 0. In the adjusted model, there was evidence of an interaction between OB-CMI and maternal race and ethnicity (p = 0.01). After adjusting for potential confounders, including SVI, non-Hispanic Black patients had the highest odds of SMM among patients with an OB-CMI score category of 1 and ≥4 compared with non-Hispanic White patients with an OB-CMI score of 0 (adjusted odds ratio [aOR] = 2.76, 95% confidence interval [CI]: 2.08-3.66 and aOR = 10.07, 95% CI: 8.42-12.03, respectively). The association between SVI and SMM was not significant on adjusted analysis. CONCLUSION OB-CMI was significantly associated with SMM, with higher score categories associated with higher odds of SMM. A significant interaction between OB-CMI and maternal race and ethnicity was identified, revealing racial disparities in the odds of SMM within each higher OB-CMI score category. SVI was not associated with SMM after adjusting for confounders. KEY POINTS · OB-CMI was significantly associated with SMM.. · Racial disparities were seen within each OB-CMI score group.. · SVI was not associated with SMM on adjusted analysis..

Abstract
OBJECTIVE Severe maternal morbidity (SMM) has disproportionate frequencies among racial minorities and those of socioeconomic disadvantage, with people of Black race consistently having the highest proportion. Neighborhood level deprivation has been associated with maternal morbidity and mortality, including adverse pregnancy outcomes. We sought to explore the relationship between neighborhood socioeconomic disadvantage and SMM and describe how neighborhood context impacts the relationship between race and SMM. STUDY DESIGN We performed a retrospective cohort analysis of all delivery admissions in a single health care network from 2015 to 2019. Area deprivation index (ADI) was used to represent neighborhood socioeconomic disadvantage and is a composite index of neighborhood that spans income, education, household characteristics, and housing. The index ranges from 1 to 100 with higher values indicating higher disadvantage. Logistic regression assessed the relationship between ADI and SMM and estimated the effect that ADI has on the relationship between race and SMM. RESULTS Of the 63,208 birthing persons in our cohort, the unadjusted incidence of SMM was 2.2%. ADI was significantly associated with SMM, with higher values conferring higher risk for SMM (p < 0.001). The absolute risk of SMM increased roughly by 1.0% from the lowest to highest ADI value. Those of Black race had the highest unadjusted incidence of SMM compared with the referent group (3.4 vs. 2.0%) and highest median ADI (92; interquartile range [IQR]: 20). In the multivariable model, in which the primary exposure was race and ADI was adjusted for, Black race had a 1.7 times odds SMM when compared with White race (95% confidence interval [CI]: 1.5-1.9). This association was attenuated to 1.5 adjusted odds when controlling for ADI (95% CI: 1.3-1.7). Risk attenuation for SMM was not seen in other race categories. CONCLUSION Neighborhood context contributes to SMM but does not explain the majority of racial disparities. KEY POINTS · Neighborhood context is associated with SMM, with higher disadvantage conferring higher risk.. · Compared with White race, all other races had higher rates of SMM, with Black race having the highest.. · Accounting for neighborhood modestly attenuates the magnitude of association of Black race with SMM.. · Neighborhood context contributes to health outcomes but does not explain the majority of disparities..

Abstract
BACKGROUND Hypertensive disorders of pregnancy are a leading preventable cause of severe maternal morbidity and maternal mortality worldwide. OBJECTIVE To assess the improvement in hospital care processes and patient outcomes associated with hypertensive disorders of pregnancy after introduction of a statewide Severe Maternal Hypertension Quality Improvement Initiative. STUDY DESIGN A prospective cohort design comparing outcomes before and after introduction of the Illinois Perinatal Quality Collaborative statewide hypertension quality improvement initiative among 108 hospitals across Illinois. Participating hospitals recorded data for all cases of new-onset severe hypertension (>160 mm Hg systolic or >110 mm Hg diastolic) during pregnancy through 6 weeks postpartum from May 2016 to December 2017. Introduction of the statewide quality improvement initiative included implementation of severe maternal hypertension protocols, standardized patient education and discharge planning, rapid access to medications and standardized treatment order sets, and provider and nurse education. The main outcome measure was the reduction of severe maternal morbidity for pregnant/postpartum patients with severe hypertension. Key process measures include time to treatment of severe hypertension, frequency of provider/nurse debriefs, appropriate patient education, and early postpartum follow-up. RESULTS Data were reported for 8073 cases of severe maternal hypertension. The frequency of patients with new-onset severe hypertension treated within 60 minutes increased from 41% baseline to 87% (P<.001) at the end of the initiative. The initiative was associated with increased proportion of patients receiving preeclampsia education at discharge (41% to 89%; P<.001), scheduling follow-up appointments within 10 days of discharge (68% to 83%; P<.001), and having a care team debrief after severe hypertension was diagnosed (17% to 59%; P<.001). Conversely, severe maternal morbidity was reduced from 11.5% baseline to 8.4% (P<.002) at the end of the study period. Illinois hospitals have achieved time to treatment goal regardless of hospital characteristics including geography, birth volume, and patient mix. CONCLUSION Introduction of a statewide quality improvement effort was associated with improved time to treatment of severe hypertension and increased frequency of provider/nurse debriefs, appropriate patient education, and early postpartum follow-up scheduled at discharge, and reduced severe maternal morbidity.

Abstract
OBJECTIVE To compare the risk of severe maternal morbidity (SMM) from the delivery admission to 42 days' postdischarge among persons with sickle cell disease (SCD) to those without SCD. STUDY DESIGN This retrospective cohort study included deliveries ≥20 weeks' gestation at an urban safety net hospital in Atlanta, GA from 2011 to 2019. The exposure was SCD diagnosis. The outcome was a composite of SMM from the delivery admission to 42 days' postdischarge. SMM indicators as defined by the Centers for Disease Control and Prevention were identified using the International Classification of Diseases, Ninth and Tenth Revisions (ICD-9/10) codes; transfusion of blood products and sickle cell crisis were excluded. RESULTS Of N = 17,354 delivery admissions, n = 92 (0.53%) had SCD. Persons with SCD versus without SCD had an increased risk of composite SMM (15.22 vs. 2.29%, p < 0.001), acute renal failure (6.52 vs. 0.71%, p < 0.001), acute respiratory distress syndrome (4.35 vs. 0.17%, p < 0.001), puerperal cerebrovascular disorders (3.26 vs. 0.10%, p < 0.001), sepsis (4.35 vs. 0.42%, p < 0.01), air and thrombotic embolism (5.43 vs. 0.10%, p < 0.001), and ventilation (2.17 vs. 0.09%, p < 0.01). Ultimately, those with SCD had an approximately 6-fold higher incidence risk ratio of SMM, which remained after adjustment for confounders (adjusted incidence risk ratio [aIRR]: 5.96, 95% confidence interval [CI]: 3.4-9.19, p < 0.001). Persons with SCD in active vaso-occlusive crisis at the delivery admission had an approximately 9-fold higher risk of SMM up to 42 days' postdischarge compared with those with SCD not in crisis at the delivery admission (incidence: 25.71 vs. 8.77%, p < 0.05; aIRR: 8.92, 95% CI: 4.5-10.04, p < 0.05). Among those with SCD, SMM at the delivery admission was primarily related to renal and cerebrovascular events, whereas most postpartum SMM was related to respiratory events or sepsis. CONCLUSION SCD is significantly associated with an increased risk of SMM during the delivery admission and through 42 days' postdischarge. Active crisis at delivery further increases the risk of SMM. KEY POINTS · Sickle cell disease was associated with an approximately 6-fold increased risk of SMM.. · Active vaso-occlusive crisis at delivery was associated with an approximately 9-fold increased risk of SMM.. · 48% of SMM events in persons with SCD occurred postpartum and were respiratory- or sepsis-related..

Abstract
BACKGROUND Severe maternal morbidity has been increasing in the past few decades. Few studies have examined the risk of severe maternal morbidity among individuals with stillbirths vs individuals with live-birth deliveries. OBJECTIVE This study aimed to examine the prevalence and risk of severe maternal morbidity among individuals with stillbirths vs individuals with live-birth deliveries during delivery hospitalization as a primary outcome and during the postpartum period as a secondary outcome. STUDY DESIGN This was a retrospective cohort study using birth and fetal death certificate data linked to hospital discharge records from California (2008-2018), Michigan (2008-2020), Missouri (2008-2014), Pennsylvania (2008-2014), and South Carolina (2008-2020). Relative risk regression analysis was used to examine the crude and adjusted relative risks of severe maternal morbidity along with 95% confidence intervals among individuals with stillbirths vs individuals with live-birth deliveries, adjusting for birth year, state of residence, maternal sociodemographic characteristics, and the obstetric comorbidity index. RESULTS Of the 8,694,912 deliveries, 35,012 (0.40%) were stillbirths. Compared with individuals with live-birth deliveries, those with stillbirths were more likely to be non-Hispanic Black (10.8% vs 20.5%); have Medicaid (46.5% vs 52.0%); have pregnancy complications, including preexisting diabetes mellitus (1.1% vs 4.3%), preexisting hypertension (2.3% vs 6.2%), and preeclampsia (4.4% vs 8.4%); have multiple pregnancies (1.6% vs 6.2%); and reside in South Carolina (7.4% vs 11.6%). During delivery hospitalization, the prevalence rates of severe maternal morbidity were 791 cases per 10,000 deliveries for stillbirths and 154 cases per 10,000 deliveries for live-birth deliveries, whereas the prevalence rates for nontransfusion severe maternal morbidity were 502 cases per 10,000 deliveries for stillbirths and 68 cases per 10,000 deliveries for live-birth deliveries. The crude relative risk for severe maternal morbidity was 5.1 (95% confidence interval, 4.9-5.3), whereas the adjusted relative risk was 1.6 (95% confidence interval, 1.5-1.8). For nontransfusion severe maternal morbidity among stillbirths vs live-birth deliveries, the crude relative risk was 7.4 (95% confidence interval, 7.0-7.7), whereas the adjusted relative risk was 2.0 (95% confidence interval, 1.8-2.3). This risk was not only elevated among individuals with stillbirth during the delivery hospitalization but also through 1 year after delivery (severe maternal morbidity adjusted relative risk, 1.3; 95% confidence interval, 1.1-1.4; nontransfusion severe maternal morbidity adjusted relative risk, 1.2; 95% confidence interval, 1.1-1.3). CONCLUSION Stillbirth was found to be an important contributor to severe maternal morbidity.

Sweeney LC, Reddy UM, Campbell K, Xu X. Postpartum readmission risk: a comparison between stillbirths and live births. Am J Obstet Gynecol 2024:S0002-9378(24)00089-9. [PMID: 38367754 DOI: 10.1016/j.ajog.2024.02.017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2023] [Revised: 01/29/2024] [Accepted: 02/09/2024] [Indexed: 02/19/2024]
Abstract
BACKGROUND Stillbirth occurs more commonly among pregnant people with comorbid conditions and obstetrical complications. Stillbirth also independently increases maternal morbidity and imparts a psychosocial hazard when compared with live birth. These distinct needs and burden may increase the risk for postpartum readmission after stillbirth. OBJECTIVE This study aimed to examine the risk for maternal postpartum readmission after stillbirth in comparison with live birth and to identify indications for readmission and the associated risk factors. STUDY DESIGN This was a retrospective cohort of patients with singleton stillbirths or live births, delivered at ≥20 weeks' gestation, who were identified from the 2019 Nationwide Readmissions Database. The primary outcome was all-cause readmission within 6 weeks of discharge from the childbirth hospitalization. The association between stillbirth (vs live birth) and risk for readmission was assessed using multivariable regression models with adjustment for maternal age, sociodemographic characteristics, maternal and obstetrical conditions, and delivery characteristics. Within the stillbirth group, risk factors for readmission were further examined using multivariable regression. The secondary outcomes included principal indication for readmission (categorized based on principal diagnosis code of the readmission hospitalization) and timing of readmission (number of weeks after childbirth hospitalization). Differences in these secondary outcomes were compared between the stillbirth and live birth groups using chi-square tests. All analyses accounted for the complex sample design to generate nationally representative estimates. RESULTS Postpartum readmission occurred in 2.7% of 16,636 patients with stillbirths, whereas it occurred in 1.6% of 2,870,677 patients with live births (unadjusted risk ratio, 1.65; 95% confidence interval, 1.47-1.86). The higher risk for readmission after stillbirth (vs live birth) persisted after adjusting for maternal, obstetrical, and delivery characteristics (adjusted risk ratio, 1.27; 95% confidence interval, 1.11-1.46). The distribution of principal indication for readmission differed after stillbirth and after live birth and included hypertension (30.2% vs 39.5%; unadjusted risk ratio, 0.76; 95% confidence interval, 0.63-0.93), mental health or substance use disorders (6.8% vs 3.6%; unadjusted risk ratio, 1.90; 95% confidence interval, 1.15-3.16), and venous thromboembolism (5.8% vs 2.0%; unadjusted risk ratio, 2.87; 95% confidence interval, 1.60-5.17). Among patients with stillbirths, 56.0% of readmissions occurred within 1 week, 71.8% within 2 weeks, and 88.1% within 4 weeks; the timing of readmission did not differ significantly between the stillbirth and live birth cohorts. Pregestational diabetes (adjusted risk ratio, 1.87; 95% confidence interval, 1.20-2.93), gestational diabetes (adjusted risk ratio, 1.67; 95% confidence interval, 1.03-2.71), hypertensive disorders of pregnancy (adjusted risk ratio, 1.80; 95% confidence interval, 1.31-2.47), obesity (adjusted risk ratio, 1.46; 95% confidence interval, 1.01-2.12), and primary cesarean delivery (adjusted risk ratio, 1.74; 95% confidence interval, 1.17-2.58) were associated with a higher risk for readmission after stillbirth, whereas higher household income was associated with a lower risk for readmission (eg, adjusted risk ratio for income ≥$82,000 vs $1-$47,999, 0.48; 95% confidence interval, 0.30-0.77). CONCLUSION When compared with live births, the risk for postpartum readmission was higher after stillbirths, even after adjustment for differences in the patient demographic and clinical characteristics. Readmission for mental health or substance use disorders and venous thromboembolism is more common after stillbirths than after live births.

Abstract
INTRODUCTION Pain is the most common postpartum concern and has been associated with adverse outcomes, such as difficulty with neonatal bonding, postpartum depression, and persistent pain. Furthermore, racial and ethnic disparities in the management of postpartum pain are well described. Despite this, less is known regarding patients' lived experiences regrading postpartum pain. The purpose of this study was to assess patient experiences related to postpartum pain management after cesarean birth. METHODS This is a prospective qualitative study of patients' experiences with postpartum pain management after cesarean birth at a single large tertiary care center. Individuals were eligible if they had publicly funded prenatal care, were English or Spanish speaking, and underwent a cesarean birth. Purposive sampling was used to ensure a racially and ethnically diverse cohort. Participants underwent in-depth interviews using a semistructured interview guide at 2 time points: postpartum day 2 to 3 and 2 to 4 weeks after discharge. Interviews addressed perceptions and experiences of postpartum pain management and recovery. Data were analyzed using the constant comparative method. RESULTS Of 49 participants, 40.8% identified as non-Hispanic Black and 40.8% as Hispanic. The majority (59.2%) had experienced a cesarean birth with a prior pregnancy. Thematic analysis yielded 2 overarching domains: (1) experience of pain after cesarean birth and (2) pain management and opioid use after cesarean birth. Themes related to the experience of pain included pain as a meaningful experience, pain not aligned with expectations, and limitations caused by pain. All participants discussed limitations caused by their pain, voicing frustration with pursuing activities of daily living, caring for home and family, caring for neonate, and impact on mood. Themes related to pain management and opioid use addressed a desire for nonpharmacologic pain management, positive and negative experiences using opioids, and hesitancy and perceived judgement regarding opioid use. Several participants described experiences of judgement regarding the request for opioids and needing stronger pain medications, such as oxycodone. DISCUSSION Understanding experiences regarding postpartum cesarean pain management and recovery is essential to improving patient-centered care. The experiences identified by this analysis highlight the need for individualized postpartum pain management, improved expectation counseling, and the expansion of multimodal pain management options.

Abstract
OBJECTIVE Individuals who deliver preterm are disproportionately affected by severe maternal morbidity. Limited data suggest that indicator-specific maternal morbidity varies by gestational age at delivery. We sought to evaluate the relationship between gestational age at delivery and the incidence of severe maternal morbidity and indicator-specific severe maternal morbidity. METHODS We used a hospital administrative delivery database to identify all singleton deliveries between 16 and 42 weeks gestation from 2002 to 2018. We defined severe maternal morbidity as the presence of any International Classification of Disease diagnosis or procedure codes outlined by the Centers for Disease Control and Prevention, intensive care unit admission, and/or prolonged postpartum hospital length of stay. Indicator-specific severe maternal morbidity was based on the diagnosis and procedure codes and was characterized across gestational age epochs. We categorized gestational age into three epochs to capture extremely preterm birth (less than 28 weeks gestation), preterm birth (28-36 weeks gestation) and term birth (37 weeks gestation and above). Multivariable binomial regression was used to assess the association between categories of gestational age at delivery and severe maternal morbidity adjusting for confounders including age, race, body mass index (BMI), insurance status, and preexisting hypertension or diabetes. RESULTS Severe maternal morbidity occurred in 2.5% of all deliveries. The unadjusted incidence of severe maternal morbidity by gestational age epoch was 12% at less than 28 weeks gestation, 8.4% at 28 to 36 weeks of gestation, and 1.7% at greater than or equal to 37 weeks gestation. After controlling for potential confounders the predicted probability of severe maternal morbidity was 16% (95% CI 14,17%) at 24 weeks compared to 2.2% (95% CI 2.1,2.3%) at 38 weeks. Sepsis, acute respiratory distress syndrome, mechanical ventilation, and shock were the most common diagnostic codes in deliveries less than 28 weeks gestation. Heart failure and cardiac arrhythmias were more common in patients with severe maternal morbidity delivering at term. CONCLUSION A high proportion of severe maternal morbidity occurred in preterm patients, with the highest rates occurring at less than 28 weeks gestation. Individuals with severe maternal morbidity who deliver preterm had distinct indicators of morbidity compared to those who deliver at term.

Abstract
BACKGROUND Postpartum hemorrhage (PPH) is a leading cause of maternal morbidity and mortality. Twin pregnancy and cesarean delivery are well-known risk factors for PPH. However, few studies have investigated PPH risk factors in mothers who have undergone cesarean delivery for twin pregnancies. Therefore, this study investigated the risk factors associated with severe PPH after cesarean delivery for twin pregnancies. METHODS We searched and reviewed the Korean Health Insurance Review and Assessment Service's claims data from July 2008 to June 2021 using the code corresponding to cesarean delivery for twin pregnancy. Severe PPH was defined as hemorrhage requiring red blood cell (RBC) transfusion during the peripartum period. The risk factors associated with severe PPH were identified among the procedure and diagnosis code variables and analyzed using univariate and multivariate logistic regressions. RESULTS We analyzed 31,074 cesarean deliveries for twin pregnancies, and 4,892 patients who underwent cesarean deliveries for twin pregnancies and received RBC transfusions for severe PPH were included. According to the multivariate analysis, placental disorders (odds ratio, 4.50; 95% confidence interval, 4.09- 4.95; P < 0.001), general anesthesia (2.33, 2.18-2.49; P < 0.001), preeclampsia (2.20, 1.99-2.43; P < 0.001), hemolysis, elevated liver enzymes, low platelets (HELLP) syndrome (2.12, 1.22-3.68; P = 0.008), induction failure (1.37, 1.07-1.76; P = 0.014), and hypertension (1.31, 1.18-1.44; P < 0.001) predicted severe PPH. CONCLUSIONS Placental disorders, hypertensive disorders such as preeclampsia and HELLP syndrome, and induction failure increased the risk of severe PPH after cesarean delivery for twin pregnancy.

Soc Sci Med 2023; 334:116196.

Abstract
Gentrification, a racialized and profit-driven process in which historically disinvested neighborhoods experience an influx of development that contributes to the improvement of physical amenities, increasing housing costs, and the dispossession and displacement of existing communities, may influence the risk of severe maternal morbidity (SMM). Leveraging a racially diverse population-based sample of all live hospital births in California between 2006 and 2017, we examined associations between neighborhood-level gentrification and SMM. SMM was defined as having one of 21 procedures and diagnoses, as described in the SMM index developed by Centers for Disease Control and Prevention. We compared three gentrification measures to determine which operationalization best captures aspects of gentrification most salient to SMM: Freeman, Landis 3-D, and Urban Displacement Project Gentrification and Displacement Typology. Descriptive analysis assessed bivariate associations between gentrification and birthing people's characteristics. Overall and race and ethnicity-stratified mixed-effects logistic models assessed associations between gentrification and SMM, adjusting for individual sociodemographic and pregnancy factors while accounting for clustering by census tract. The study sample included 5,256,905 births, with 72,718 cases of SMM (1.4%). The percentage of individuals living in a gentrifying neighborhood ranged from 5.7% to 11.7% across exposure assessment methods. Net of individual and pregnancy-related factors, neighborhood-level gentrification, as measured by the Freeman method, was protective against SMM (OR = 0.89, 95% CI: 0.86-0.93); in comparison, gentrification, as measured by the Gentrification and Displacement Typology, was associated with greater risk of SMM (OR = 1.18, 95% CI: 1.14-1.23). These associations were significant among non-Hispanic White, non-Hispanic Black, and Hispanic individuals. Findings demonstrate that gentrification plays a role in shaping the risk of SMM among birthing people in California. Differences in how gentrification is conceptualized and measured, such as an emphasis on housing affordability compared to a broader characterization of gentrification's multiple aspects, may explain the heterogeneity in the directions of observed associations.

Abstract
BACKGROUND Major fetal malformations complicate 2% to 5% of live births. It is unclear what effect fetal malformations have on severe maternal morbidity. OBJECTIVE This study aimed to compare maternal outcomes between individuals with a fetus with major or minor fetal malformations and those with a fetus without major or minor fetal malformations. STUDY DESIGN This was a secondary analysis of the Consortium on Safe Labor database. Our study was limited to the current analysis of pregnant individuals with a singleton live birth. Major fetal malformations based on the Centers for Disease Control and Prevention's criteria were defined. Fetal malformations that did not meet the criteria for major fetal malformations were categorized as minor fetal malformations. Our primary maternal outcome was severe maternal morbidity as defined by the Centers for Disease Control and Prevention. Missing values were imputed by multiple imputation using the k-nearest neighbor imputation method. Poisson regression with robust error variance was used to obtain adjusted relative risks with 95% confidence intervals, controlling for confounders. RESULTS Of 216,881 deliveries, there were 201,860 cases (93.1%) with no congenital malformation, 12,106 cases (5.6%) with minor fetal malformations, and 2845 cases (1.3%) with major fetal malformations. Compared with individuals with no fetal malformation, those with major fetal malformations were more likely to have severe maternal morbidity (0.7% vs 1.2%; adjusted relative risk, 1.51; 95% confidence interval, 1.07-2.12), postpartum hemorrhage (3.6% vs 6.9%; adjusted relative risk, 1.76; 95% confidence interval, 1.50-2.06), preeclampsia (5.1% vs 8.3%; adjusted relative risk, 1.48; 95% confidence interval, 1.31-1.67), and cesarean delivery (26.7% vs 42.3%; adjusted relative risk, 1.51; 95% confidence interval, 1.45-1.58). Compared with individuals with no fetal malformation, those with minor fetal malformations were more likely to have severe maternal morbidity (0.7% vs 1.4%; adjusted relative risk, 1.73; 95% confidence interval, 1.48-2.02), maternal death (0.01% vs 0.03%; adjusted relative risk, 4.50; 95% confidence interval, 1.18-17.19), postpartum hemorrhage (3.6% vs 6.1%; adjusted relative risk, 1.54; 95% confidence interval, 1.41-1.68), preeclampsia (5.1% vs 8.6%; adjusted relative risk, 1.50; 95% confidence interval, 1.41-1.60), superimposed preeclampsia (1.2% vs 2.4%; adjusted relative risk, 1.25; 95% confidence interval, 1.14-1.38), cesarean delivery (26.7% vs 39.6%; adjusted relative risk, 1.38; 95% confidence interval, 1.35-1.41), chorioamnionitis (3.0% vs 4.7%; adjusted relative risk, 1.41; 95% confidence interval, 1.29-1.53), and postpartum endometritis (0.6% vs 1.0%; adjusted relative risk, 1.58; 95% confidence interval, 1.31-1.90). CONCLUSION Major and minor congenital fetal malformations are independent risk factors for severe maternal morbidity and other pregnancy complications.

[PMID: 36420897 PMCID: PMC10373920 DOI: 10.1111/ppe.12935] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/16/2022] [Revised: 10/20/2022] [Accepted: 10/22/2022] [Indexed: 11/25/2022]
Abstract
BACKGROUND Historical mortgage redlining, a racially discriminatory policy designed to uphold structural racism, may have played a role in producing the persistently elevated rate of severe maternal morbidity (SMM) among racialised birthing people. OBJECTIVE This study examined associations between Home-Owner Loan Corporation (HOLC) redlining grades and SMM in a racially and ethnically diverse birth cohort in California. METHODS We leveraged a population-based cohort of all live hospital births at ≥20 weeks of gestation between 1997 and 2017 in California. SMM was defined as having one of 21 procedures and diagnoses, per an index developed by Centers for Disease Control and Prevention. We characterised census tract-level redlining using HOLC's security maps for eight California cities. We assessed bivariate associations between HOLC grades and participant characteristics. Race and ethnicity-stratified mixed effects logistic regression models assessed the risk of SMM associated with HOLC grades within non-Hispanic Black, Asian/Pacific Islander, American Indian/Alaskan Native and Hispanic groups, adjusting for sociodemographic information, pregnancy-related factors, co-morbidities and neighbourhood deprivation index. RESULTS The study sample included 2,020,194 births, with 24,579 cases of SMM (1.2%). Living in a census tract that was graded as "Hazardous," compared to census tracts graded "Best" and "Still Desirable," was associated with 1.15 (95% confidence interval [CI] 1.03, 1.29) and 1.17 (95% CI 1.09, 1.25) times the risk of SMM among Black and Hispanic birthing people, respectively, independent of sociodemographic factors. These associations persisted after adjusting for pregnancy-related factors and neighbourhood deprivation index. CONCLUSIONS Historical redlining, a tool of structural racism that influenced the trajectory of neighbourhood social and material conditions, is associated with increased risk of experiencing SMM among Black and Hispanic birthing people in California. These findings demonstrate that addressing the enduring impact of macro-level and systemic mechanisms that uphold structural racism is a vital step in achieving racial and ethnic equity in birthing people's health.

Abstract
The surgical management of placenta accreta spectrum (PAS) is often challenging. There are a variety of techniques and management options described in the literature ranging from uterine sparing to cesarean hysterectomy. Following the inaugural meeting of the Pan-American Society for Placenta Accreta Spectrum a multidisciplinary group collaborated to describe collective recommendations for the surgical management of PAS. In this manuscript, we outline individual components of the procedure and provide suggested direction at key points of a cesarean hysterectomy in the setting of PAS. KEY POINTS: · The surgical management of PAS requires careful planning and expertise.. · Multidisciplinary team care for pregnancies complicated by PAS can decrease morbidity and mortality.. · Careful surgical techniques can minimize risk of significant hemorrhage by avoiding pitfalls..

Abstract
BACKGROUND The experience of pain is shaped by a host of psychological, cultural, and social factors. Although pain is the most common postpartum complaint, data on its relationship with psychosocial factors and postpartum pain are limited. OBJECTIVE This study aimed to examine the relationship between self-reported postpartum pain scores and patient-level psychosocial factors, including relationship status, pregnancy intendedness, employment, education, and psychiatric diagnosis. STUDY DESIGN This was a secondary analysis of data from a prospective observational study of postpartum patients at 1 institution (May 2017 to July 2019) who used an oral opioid at least once during their postpartum hospitalization. Enrolled participants completed a survey, which included questions regarding their social situation (including relationship status), psychiatric diagnoses, and perceptions of their pain control during their postpartum hospitalization. The primary outcome was self-reported overall pain during the postpartum hospitalization (score of 0-100). Multivariable analyses accounted for age, body mass index, nulliparity, and mode of delivery. RESULTS In this cohort of 494 postpartum patients, most patients (84.0%) underwent cesarean delivery, and 41.3% of patients were nulliparous. In a pain score of 0 to 100, participants reported a median pain score of 47. On bivariable analyses, there was no significant difference in pain score between patients with and without an unplanned pregnancy or a psychiatric diagnosis. Patients who were unpartnered, those without a college education, and those who were unemployed reported significantly higher pain scores (57.5 vs 44.8 [P<.01], 52.6 vs 44.6 [P<.01], and 53.6 vs 44.6 [P<.01], respectively). In multivariable analyses, patients who were unpartnered and unemployed reported significantly higher adjusted pain scores than patients who were partnered and employed (adjusted beta coefficients: 7.93 [95% confidence interval, 2.29-13.57] vs 6.67 [95% confidence interval, 2.28-11.05]). CONCLUSION Psychosocial factors, such as relationship and employment statuses, which are indicators of social support, are associated with the experience of pain postpartum. These findings suggest that addressing social support, such as via enhanced support from the health care team, warrants exploration as a nonpharmacologic means of improving the postpartum pain experience.

Abstract
BACKGROUND The infrastructure of many labor and delivery units in the United States may dispose clinicians to overuse continuous and automated maternal physiological monitors. Overmonitoring low-risk patients can negatively affect patient care, primarily through generating alarm fatigue. OBJECTIVE Given the national attention to reducing alarm fatigue across healthcare settings and the concern for vital sign monitoring overuse on our labor and delivery unit, this quality improvement study aimed to evaluate vital sign monitoring patterns and alarm rates, and nursing experiences of alarm fatigue, before and after implementing a vital sign monitoring guideline for low-risk obstetrical patients. STUDY DESIGN This was a quality improvement study conducted on the labor and delivery unit of an urban, academic, tertiary hospital. The lack of guidance for maternal vital sign assessment in low-risk patients was identified as a potential safety challenge. A vital sign guideline was developed with multidisciplinary input, followed by a pre-post-implementation study evaluating vital sign volume and alarm rates. Total vital signs and alarm rates for all patients delivered during designated calendar days were assessed as a rate of vital signs per patient and compared across baseline, peri-intervention, and follow-up periods. Data were examined in p-type statistical process control charts and with time-series analysis. Patient characteristics and severe maternal morbidity, as a balancing metric, were compared across periods. Nursing perceptions of vital sign monitoring and experience of alarm fatigue were assessed via survey before and after implementation of the guideline. RESULTS A total of 35 individual 24-hour periods were evaluated with regard to vital sign and alarm volume. There was a decrease in vital signs per patient from a mean of 208.34 to 135.46 (incidence rate ratio, 0.65) and in alarms per patient from a mean of 14.31 to 10.51 (incidence rate ratio, 0.73) after implementation, with no difference in severe maternal morbidity. There were 85 total respondents to the nursing surveys, and comparison of modified task-load index scores before and after implementation demonstrated overall lower scores in the postperiod, although these were not statistically significant. CONCLUSION Introducing a maternal vital sign guideline for low-risk patients on the labor and delivery unit decreased vital signs measured as well as alarms, which may ultimately reduce alarm fatigue. This strategy should be considered on labor and delivery units widely to improve patient safety and optimize outcomes.

Abstract
OBJECTIVE This study aimed to determine whether specific factors of the built environment related to physical activity and diet are associated with inadequate and excessive gestational weight gain (GWG). STUDY DESIGN This analysis is based on data from the Nulliparous Pregnancy Outcomes Study: Monitoring Mothers-To-Be, a prospective cohort of nulliparous women who were followed from the beginning of their pregnancies through delivery. At each study visit, home addresses were recorded and geocoded. Locations were linked to several built-environment characteristics such as the census tract National Walkability Score (the 2010 Walkability Index) and the number of gyms, parks, and grocery stores within a 3-km radius of residential address. The primary outcome of GWG (calculated as the difference between prepregnancy weight and weight at delivery) was categorized as inadequate, appropriate, or excessive based on weight gained per week of gestation. Multinomial regression (generalized logit) models evaluated the relationship between each factor in the built environment and excessive or inadequate GWG. RESULTS Of the 8,182 women in the analytic sample, 5,819 (71.1%) had excessive GWG, 1,426 (17.4%) had appropriate GWG, and 937 (11.5%) had inadequate GWG. For the majority of variables examined, built environments more conducive to physical activity and healthful food availability were associated with a lower odds of excessive or inadequate GWG category. For example, a higher number of gyms or parks within 3 km of a participant's residential address was associated with lower odds of having excessive (gyms: adjusted odds ratio [aOR] = 0.93 [0.89-0.96], parks: 0.94 [0.90-0.98]) or inadequate GWG (gyms: 0.91 [0.86-0.96]; parks: 0.91 [0.86-0.97]). Similarly, a higher number of grocery stores was associated with lower odds of having excessive GWG (0.94 [0.91-0.97]). CONCLUSION Among a diverse population of nulliparous women, multiple aspects of the built environment are associated with excessive and inadequate GWG. KEY POINTS · There are little data on the association between the built environment and pregnancy outcomes.. · Multiple aspects of the built environment are associated with excessive and inadequate GWG.. · These results suggest the role that neighborhood investment may play in improving pregnancy outcomes..

Abstract
OBJECTIVE This study aimed to examine whether there are racial disparities in severe maternal morbidity (SMM) in patients with hypertensive disorders of pregnancy (HDP). STUDY DESIGN Secondary analysis of an observational study of 115,502 patients who had a live birth at ≥20 weeks in 25 hospitals in the United States from 2008 to 2011. Only patients with HDP were included in this analysis. Race and ethnicity were categorized as non-Hispanic White, non-Hispanic Black (NHB), and Hispanic and were abstracted from the medical charts. Patients of other races and ethnicities were excluded. Associations were estimated between race and ethnicity, and the primary outcome of SMM, defined as any of the following, was estimated by unadjusted logistic and multivariable backward logistic regressions: blood transfusion ≥4 units, unexpected surgical procedure, need for a ventilator ≥12 hours, intensive care unit (ICU) admission, or failure of ≥1 organ system. Multivariable models were run classifying HDP into three levels as follows: (1) gestational hypertension; (2) preeclampsia (mild, severe, or superimposed); and (3) eclampsia or HELLP (hemolysis, elevated liver enzymes, and low platelet count) syndrome. RESULTS A total of 9,612 individuals with HDP met inclusion criteria. No maternal deaths occurred in this cohort. In univariable analysis, non-Hispanic White patients were more likely to present with gestational hypertension whereas NHB and Hispanic patients were more likely to present with preeclampsia. The frequency of the primary outcome, composite SMM, was higher in NHB patients compared with that in non-Hispanic White or Hispanic patients (11.8 vs. 4.5% in non-Hispanic White and 4.8% in Hispanic, p < 0.001). This difference was driven by a higher frequency of blood transfusions and ICU admissions among NHB individuals. Prior to adjusting the analysis for confounding factors, the odds ratio (OR) of primary composite outcomes in NHB individuals was 2.85 (95% confidence interval [CI]: 2.38, 3.42) compared with non-Hispanic White. After adjusting for sociodemographic and clinical factors, hospital site, and the severity of HDP, the OR of composite SMM did not differ between the groups (adjusted OR [aOR] = 1.26, 95% CI: 0.95, 1.67 for NHB, and aOR = 1.29, 95% CI: 0.94, 1.77 for Hispanic, compared with non-Hispanic White patients). Sensitivity analysis was done to exclude one single site that was an outliner with the highest ICU admissions and demonstrated no difference in ICU admission by maternal race and ethnicity. CONCLUSION NHB patients with HDP had higher rates of the composite SMM compared with non-Hispanic White patients, driven mainly by a higher frequency of blood transfusions and ICU admissions. However, once severity and other confounding factors were taken into account, the differences did not persist. KEY POINTS · Black patients with HDP had higher frequency of SMM compared with non-Hispanic White patients.. · The SMM disparities were driven by blood transfusions and ICU admissions.. · After adjustment for confounders, including HDP severity, the significant difference in SMM did not persist..

Abstract
Iron deficiency anemia during pregnancy is a common concern, affecting 38% of women worldwide and up to 50% in developing countries. It is defined differently throughout all 3 trimesters. It has several detrimental effects on pregnancy outcomes for both the mother and the fetus, such as increasing the risk for postpartum depression, preterm delivery, cesarean delivery, preeclampsia, and low birthweight. Management of iron deficiency anemia is done classically via oral iron supplementation. However, recent evidence has shown that intravenous iron is a good alternative to oral iron if patients are unable to tolerate it, not responding, or present with a new diagnosis very late in pregnancy. Management of iron deficiency anemia was demonstrated to be protective against postpartum hemorrhage. Other ways to prevent postpartum hemorrhage include improving prediction tools that can identify those at risk. Several risk assessment kits have been developed to estimate the risk for postpartum hemorrhage among patients and have been proven useful in the prediction of patients at high risk for postpartum hemorrhage despite limitations among low-risk groups. More comprehensive tools are also being explored by determining clinically relevant factors through nomograms, with some proving their efficacy after implementation. Machine learning is also being used to develop more complete tools by including risk factors previously not accounted for. These newer tools, however, still require external validation before being adopted despite promising results under testing conditions.

Abstract
BACKGROUND There are persistent racial/ethnic disparities in the occurrence of severe maternal morbidity. Patient-centered medical home care has the potential to address disparities in maternal outcomes. OBJECTIVES To examine (1) the association between receiving patient-centered medical home care and severe maternal morbidity outcomes and (2) the interaction of race/ethnicity on patient-centered medical home status and severe maternal morbidity. DESIGN/METHODS Using 2007 to 2016 data from the Medical Expenditures Panel Survey, we conducted a cross-sectional study to estimate the association between receipt of care from a patient-centered medical home and the occurrence of severe maternal morbidity, and racial-specific (White, Black, Asian, Other) relative risks of severe maternal morbidity. Our study used race as a proxy measure for exposure racism. We identified mothers (⩾15 years) who gave birth during the study period. We identified patient-centered medical home qualities using 11 Medical Expenditures Panel Survey questions and severe maternal morbidities using medical claims, and calculated generalized estimating equation models to estimate odds ratios of severe maternal morbidity and 95% confidence intervals. RESULTS Among all mothers who gave birth (N = 2801; representing 5,362,782 US lives), only 25% received some exposure patient-centered medical home care. Two percent experienced severe maternal morbidity, and this did not differ statistically (p = 0.11) by patient-centered medical home status. However, our findings suggest a 85% decrease in the risk of severe maternal morbidity among mothers who were defined as always attending a patient-centered medical home (odds ratios: 0.15; 95% confidence interval:0.01-1.87; p = 0.14) and no difference in the risk of severe maternal morbidity among mothers who were defined as sometimes attending a patient-centered medical home (odds ratios: 1.00; 95% confidence interval:0.16-6.42; p = 1.00). There was no overall interaction effect in the model between race and patient-centered medical home groups (p = 0.82), or ethnicity and patient-centered medical home groups (p = 0.62) on the severe maternal morbidity outcome. CONCLUSION While the rate of severe maternal morbidity was similar to US rates, few mothers received care from a patient-centered medical home which may be due to underreporting. Future research should further investigate the potential for patient-centered medical home-based care to reduce odds of severe maternal morbidity across racial/ethnic groups.

Abstract
Background Maternal risk factors for fetal congenital heart disease (CHD) may also be associated with delivery complications in the mother. Objectives This study aimed to determine the prevalence of and risk factors for severe maternal morbidity (SMM) and maternal hospital transfer in pregnancies complicated by fetal CHD. Methods A population-based retrospective cohort study utilizing linked Ohio birth certificates and birth defect data for all live births from 2011 to 2015 was performed. The primary outcome was composite SMM. Secondary outcome was maternal hospital transfer prior to delivery. Pregnancies with isolated fetal CHD were compared to pregnancies with no fetal anomalies and isolated fetal cleft lip/palate (CLP). Results A total of 682,929 mothers with live births were included. Of these, 5,844 (0.85%) mothers had fetal CHD, and 963 (0.14%) had fetal CLP. SMM in pregnancies with fetal CHD was higher than that in those with no anomalies (3.6% vs 1.9%, P < 0.001) or CLP (3.6% vs 1.9%, P = 0.006). After adjusting for known risk factors, fetal CHD remained independently associated with SMM when compared to no fetal anomalies (adjusted relative risk [adjRR]: 1.81, 95% CI: 1.58-2.08) and CLP (adjRR: 1.81, 95% CI: 1.12-2.92). Maternal hospital transfer occurred more frequently in fetal CHD cases vs for those without fetal anomalies with an increased adjusted risk (adjRR: 3.65, 95% CI: 3.14-4.25). Conclusions Pregnancies with isolated fetal CHD have increased risk of SMM and maternal hospital transfer after adjusting for known risk factors. This may inform delivery planning for mothers with fetal CHD. Understanding the biological mechanisms may provide insight into other adverse perinatal outcomes in this population.

Maternal Right Ventricular and Left Atrial Function in Uncomplicated Twin Pregnancies: A Longitudinal Study. J Clin Med 2022; 11:5432. [PMID: 36143080 PMCID: PMC9503833 DOI: 10.3390/jcm11185432] [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: 08/11/2022] [Revised: 09/11/2022] [Accepted: 09/13/2022] [Indexed: 11/25/2022] Open
Abstract
Objective: The knowledge regarding maternal cardiovascular hemodynamic adaptation in twin pregnancies is incomplete. We performed a longitudinal investigation of maternal right ventricular (RV) and left atrial (LA) function in a cohort of uncomplicated twin pregnancies compared to singleton pregnancies. Study design: Healthy women with uncomplicated twin pregnancies were prospectively enrolled and assessed by transthoracic echocardiography at 10−15 weeks’ (w) gestation (T1), 19-26 w gestation (T2), and 30−38 w gestation (T3). Subjects with uneventful singleton pregnancies were selected as controls at the same gestational ages. Cardiac findings were compared to those of women with uneventful singleton gestations. RV systolic and diastolic functions were assessed by conventional echocardiography (FAC, TAPSE, sPAP, E, A, DT) and tissue Doppler imaging (TDI) (E’, A’, S’, IVA, IVCT, IVRT, ET, MPI), and LA dimensions were calculated. Speckle-tracking imaging was also applied to evaluate RV global longitudinal strain and LA 2D strains (at LV end-systole (LAS) and at atrial contraction (LAA)). Results: Overall, 30 uncomplicated twin and 30 uncomplicated singleton pregnancies were included. Regarding maternal RV function in twins, all the parameters (FAC, TAPSE, sPAP, E, A, E/A, DT, E/E’, IVA, IVCT, MPI and 2D longitudinal strain) were almost stable throughout gestation, with the exception of the TDI findings (E’ decreased from T1 to T3 (p = 0.03), while E’/A’ increased from T1 to T2 and then decreased (p = 0.01); A’ and basal S’ increased (p = 0.04 and p = 0.03, respectively), while IVRT and ET significantly decreased (p = 0.009 and p = 0.007, respectively)). These findings were similar to those found for singleton pregnancies. LA dimensions significantly increased throughout gestation in both twins and singletons (p < 0.001), without intergroup difference. LA strains did not vary during either twin or singleton pregnancies, except for LAA in T1, which was higher among twins than among singletons. Conclusion: Maternal RV and LA function in uncomplicated twin pregnancies does not seem to undergo more significant changes than in singletons, being characterized by similar findings in RV systolic and diastolic functions, as well as LA dimensions and strains.

Abstract
Objective: The knowledge of maternal cardiovascular hemodynamic adaptation in twin pregnancies is incomplete. We aimed to longitudinally investigate maternal left ventricular (LV) function in uncomplicated twin pregnancies. Methods: 30 healthy and uncomplicated twin pregnant women and 30 controls with normal singleton pregnancies were prospectively enrolled to undergo transthoracic echocardiography at 10–15 week’s gestation (w) (T1), 19–26 w (T2) and 30–38 w (T3). LV dimensions and volumes, as well as LV ejection fraction (LVEF), mass (LVM) and diastolic parameters (at transmitral pulsed wave Doppler and mitral annular plane tissue Doppler), were calculated. Speckle-tracking imaging was also applied to evaluate LV global longitudinal (GLS), radial and circumferential 2D strains. Results: During twin pregnancy, maternal LV dimensions, volumes and LVM had an increasing trend from T1 to T3, similar to singletons, while LVEF remained stable. There was LV remodeling/hypertrophy in 50% of women at T2 and T3 in both groups. Diastolic function had a worsening trend from T1 to T3 with no differences between twins and singletons, except for higher LV filling pressure (i.e., E/E′) at T2 in twins. Two-dimensional strains did not vary during gestation in either group, except for a linear trend to increase (i.e., worsen) GLS in singletons. Radial and circumferential 2D strains were impaired in about half of the women at each trimester, while GLS was altered in one-fourth/one-third of them in both groups. Conclusion: Maternal LV geometry, dimensions and function are significantly impaired during twin pregnancies, in particular in the second half of gestation, with no significant differences compared to singletons.

Abstract
BACKGROUND To examine the extent of hospital-level variation in risk-adjusted rates of postpartum hemorrhage (PPH). STUDY DESIGN AND METHODS We performed a cross-sectional study examining live births in 257 California hospitals between 2011 and 2015 using linked birth certificate and maternal discharge data. PPH was measured using International Classification of Diseases Codes version 9. Mixed-effects logistic regression models were used to examine the presence and extent of hospital-level variation in PPH before and after adjustment for patient-level risk factors and select hospital characteristics (teaching status and annual delivery volume). Risk-adjusted rates of PPH were estimated for each hospital. The extent of hospital variation was evaluated using the median odds ratio (MOR) and intraclass correlation coefficient (ICC). RESULTS Our study cohort comprised 1,904,479 women who had a live birth delivery hospitalization at 247 hospitals. The median, lowest, and highest hospital-specific rates of PPH were 3.48%, 0.54%, and 12.0%, respectively. Similar rates were observed after adjustment for patient and hospital factors (3.44%, 0.60%, and 11.48%). After adjustment, the proportion of the total variation in PPH rates attributable to the hospital was low, with a MOR of 2.02 (95% confidence interval [CI]: 1.89-2.15) and ICC of 14.3% (95% CI: 11.9%-16.3%). DISCUSSION Wide variability exists in the rate of PPH across hospitals in California, not attributable to patient factors, hospital teaching status, and hospital annual delivery volume. Determining whether differences in hospital quality of care explain the unaccounted-for variation in hospital-level PPH rates should be a public health priority.

Abstract
OBJECTIVE The objective was to assess temporal trends in postpartum opioid prescribing, opioid use, and pain control satisfaction. STUDY DESIGN This is a prospective observational study of postpartum patients who delivered at a large tertiary care center (May 2017-July 2019). Inpatient patients were screened for eligibility; those meeting eligibility criteria who used inpatient opioids were approached for prospective survey participation which probed inpatient and outpatient postpartum pain control. The amount of opioids used during inpatient hospitalization and the amount of opioids prescribed at discharge were obtained from medical records. The primary outcome was the difference in opioid prescribing at discharge over time, measured by (1) the proportion of participants who received an opioid prescription at discharge and (2) for those who received an opioid prescription, the total morphine milligram equivalents of the prescription. Additional outcomes were inpatient and outpatient opioid use and patient-reported satisfaction with postpartum pain control. Trends over time were evaluated using nonparametric tests of trend. RESULTS Of 2,503 postpartum patients screened for eligibility, a majority (N = 1,425; 60.8%) did not use an opioid as an inpatient. Over the study period, there was a significant decline in the proportion of patients who used an opioid while inpatient (z-score = - 11.8; p < 0.01). Among these participants enrolled in the prospective survey study (N = 494), there was a significant decline over time in the amount of inpatient opioid use (z-score = - 2.4; p = 0.02), the proportion of participants who received an opioid prescription upon discharge (z-score = - 8.2; p < 0.01), and, when an opioid was prescribed at discharge, the total prescribed morphine milligram equivalents (z-score = - 4.3; p < 0.01). Both inpatient and outpatient satisfactions with pain control were unchanged over this time (z-score = 1.1, p = 0.27; z-score = 1.1, p = 0.29, respectively). CONCLUSION In this population, both the frequency and amount of opioid use in the postpartum period declined from 2017 to 2019. This decrease in opioid prescribing was not associated with changes in patient-reported satisfaction with pain control. KEY POINTS · From 2017 to 2019, there was a decrease in inpatient and outpatient postpartum opioid use.. · Both the proportion of postpartum patients receiving opioid prescriptions and the amount prescribed decreased.. · Patient satisfaction with postpartum pain control remained unchanged..

Abstract
OBJECTIVE To systematically review the scope and development of frameworks to promote health during the postpartum period. DATA SOURCES We searched PubMed, CINAHL, and American Psychological Association PsycInfo during May 2021. STUDY SELECTION We included English-language, peer-reviewed articles focused on frameworks for health promotion in the postpartum period. We placed no time limit on publication date. Our search resulted in 2,355 articles after we removed duplicates. After excluding articles based on titles and abstracts, we conducted full-text reviews of 23 articles. Three articles met inclusion criteria and addressed the following frameworks: Integrated Perinatal Health Framework, Perinatal Maternal Health Promotion Model, and Maternal Self-Care Framework. DATA EXTRACTION We extracted data into analytic tables that included categories for the scope, such as time frame, and criteria for the level of development of the frameworks, including the origins, concept definitions and theoretical linkages among concepts, and evidence of application in research or practice. DATA SYNTHESIS The three frameworks described in the articles included in our review covered various periods, including the reproductive life span, the first year after birth, and the first 6 weeks after birth. Overall, the frameworks were comprehensive. Most key concepts in the frameworks were defined, and some degree of relationships linking concepts was specified. Empirical referents were provided for most but not all concepts in the frameworks. Developers of the three frameworks elaborated on application in practice or health services, but only the developers of the Maternal Self-Care Framework indicated how their framework might be used in research. The Integrated Perinatal Health Framework and Maternal Self-Care Framework were partially derived from existing general theories; the methods used to develop the Perinatal Maternal Health Promotion Model were less clear. CONCLUSION The frameworks met most criteria and together provided a comprehensive strategy for health promotion during the postpartum period. Elaboration of the frameworks for application in research is needed.

Abstract
OBJECTIVE To implement a speakers bureau to educate providers, health caregivers, and staff practicing within Tennessee hospitals on evidence-based practice recommendations related to opioid use disorder in pregnancy, postpartum hemorrhage, maternal hypertension, and implicit bias. DESIGN Quality improvement project. SETTING/LOCAL PROBLEM Multiple health care facilities throughout Tennessee, where rates of pregnancy-related mortality are greater than the national average and where Black women are three times as likely as White women to die of pregnancy complications. PARTICIPANTS Speakers (n = 47) included obstetricians, advanced practice providers, and nurses. Program attendees (n = 369) included providers and caregivers representing five health care facilities. INTERVENTION/MEASUREMENTS Speakers were provided standardized training to disseminate best practice methods. Current evidence-based presentations regarding the top maternal mortality concerns were formatted for educational events at five Tennessee health care facilities. Independent outcome measures using electronic survey instruments were collected for speakers and audience participants. Speakers evaluated training methods, and participants evaluated the quality and efficacy of the information provided. RESULTS Based on speaker evaluations, 70.59% rated the quality of training as 5 of 5, and 76.47% rated the relevance of training as 5 of 5. Overall, 16 of 17 (94.1%) speakers stated that adequate training was provided. Analysis of participant evaluations reported that 57.5% were very confident (5/5) that the information learned through the speakers bureau will improve their care of pregnant and postpartum people. Additionally, 71% were very likely (5/5) to apply the information to their practice. CONCLUSION This project showed the dissemination of best practices by promoting knowledge, supporting practice change, and improving retained information in maternity providers and caregiver participants. Implementation of speakers bureaus to educate providers and caregivers within health care facilities has the potential to influence practice change and decrease maternal morbidity and mortality rates in the state of Tennessee.

Abstract
IMPORTANCE The association between body mass index (BMI, which is calculated as weight in kilograms divided by height in meters squared) and severe maternal morbidity (SMM) and/or mortality is uncertain, judging from the current evidence. OBJECTIVE To examine the association between prepregnancy BMI and SMM and/or mortality through 1 year post partum and to identify both the direct and indirect implications of maternal obesity for SMM and/or mortality by examining hypertensive disorders and pregestational diabetes as potential mediators. DESIGN, SETTING, AND PARTICIPANTS This population-based cohort study was conducted from March to October 2021 using the vital records and linked Medicaid claims data in the state of Ohio from January 1, 2012, through December 31, 2017. The cohort comprised pregnant Medicaid beneficiaries who delivered at 20 weeks' gestation or later and had prepregnancy BMI information. EXPOSURES The primary exposure was maternal prepregnancy BMI, which was categorized as follows: underweight (<18.5), healthy weight (18.5-24.9), overweight (25.0-29.9), class 1 obesity (30.0-34.9), class 2 obesity (35.0-39.9), and class 3 obesity (≥40.0). MAIN OUTCOMES AND MEASURES The primary outcome was a composite of SMM (defined using Centers for Disease Control and Prevention criteria) and/or maternal mortality between 20 weeks' gestation and 1 year post partum. Additional periods were assessed, including 20 weeks' gestation through delivery hospitalization and 20 weeks' gestation through 42 days post partum. Generalized estimating equation models were used to estimate adjusted relative risks (aRRs) for the primary outcome according to BMI category. Maternal hypertensive diseases and pregestational diabetes were assessed as potential meditators. RESULTS In a cohort of 347 497 pregnancies among 276 691 Medicaid beneficiaries (median [IQR] maternal age at delivery, 25 [21-29] years; 210 470 non-Hispanic White individuals [60.6%]), the prevalence of maternal obesity was 30.5% (n = 106 031). Composite SMM and/or mortality outcome occurred in 5.3% of pregnancies (n = 18 398). Overweight (aRR, 1.07; 95% CI, 1.03-1.11) and obesity (class 1: aRR, 1.19 [95% CI, 1.14-1.24]; class 2: aRR, 1.37 [95% CI, 1.30-1.44]; class 3: aRR, 1.71 [95% CI, 1.63-1.80]) were associated with an elevated risk of SMM and/or mortality during pregnancy to 1 year post partum compared with healthy BMI. Similar findings were observed when the follow-up period was shortened to 42 days post partum or the delivery hospitalization. Hypertension mediated 65.1% (95% CI, 64.6%-65.6%) of the association between obesity and the primary outcome. CONCLUSIONS AND RELEVANCE Results of this study showed that maternal prepregnancy obesity was associated with an elevated risk of SMM and/or mortality. Hypertensive disorders appeared to mediate this association, suggesting that improved prevention and management of hypertensive disorders in pregnancy may reduce morbidity and mortality in individuals with obesity.

Abstract
OBJECTIVE To examine the association between severe maternal morbidity (SMM) and infant health using the additional infant costs and length of stay (LOS) as markers of added clinical complexity. STUDY DESIGN Secondary data analysis using California linked birth certificate-patient discharge data for 2009-2011 (N = 1,260,457). Regression models were used to estimate the association between SMM and infant costs and LOS. RESULTS The 16,687 SMM-exposed infants experienced a $6550 (33%) increase in costs and a 0.7 (18%) day increase in LOS. Preterm infants had ($11,258 (18%) added costs and 1.3 days (8.1%) longer LOS) than term infants ($2539 (38%) added costs and 0.5 days (22%) longer LOS). CONCLUSIONS SMM was associated with increased infant costs and LOS, suggesting that SMM may have adverse health effects for infants, including term infants. The relatively larger effect on costs indicates an increase in treatment intensity (clinical severity) greater than additional LOS.

Abstract
Background Severe obstetric hemorrhage is a leading cause of severe maternal morbidity. A perinatal blood transfusion is the key factor in the treatment of severe obstetric hemorrhage. Our aim is to identify patients with a high risk of perinatal blood transfusions before Cesarean Section, which can promote the effectiveness of the treatment of severe obstetric hemorrhage, as well as improve obstetric preparations. Methods This study retrospectively analyzed the data of 71 perinatal blood transfusion patients and 170 controls, who were both underwent Cesarean Section from July 2018 to September 2019. These data were included in the training set to build the risk prediction model of needing blood transfusion. Additionally, the data of 148 patients with the same protocol from October 2019 to May 2020 were included in the validation set for model validation. A multivariable logistic regression model was used. A risk prediction nomogram was formulated per the results of the multivariate analysis. Results The strongest risk factors for perinatal blood transfusions included preeclampsia (OR = 6.876, 95% CI: 2.226–23.964), abnormal placentation (OR = 5.480, 95% CI: 2.478–12.591), maternal age (OR = 1.087, 95% CI: 1.016–1.166), predelivery hemoglobin (OR = 0.973, 95% CI: 0.948–0.998) and predelivery fibrinogen (OR = 0.479, 95% CI: 0.290–0.759). A risk prediction model of perinatal blood transfusions for cesarean sections was developed (AUC = 0.819; sensitivity: 0.735; specificity: 0.848; critical value: 0.287). Conclusions The risk prediction model can identify the perinatal blood transfusions before Cesarean Section. With the nomogram, the model can be further quantified and visualized, and clinical decision-making can subsequently be further simplified and promoted.

Abstract
BACKGROUND In the United States, approximately 52,000 women per year (accounting for 1.46% of births) experience severe maternal morbidity, which is defined as a complication that causes significant maternal harm or risk of death. It disproportionately affects women from racial or ethnic minorities, people with chronic diseases, and those with Medicaid or no insurance. Preconception care has been hailed as a strategy to improve pregnancy outcomes and reduce disparities, but its broad benefits for maternal outcomes have not been demonstrated. OBJECTIVE Our objective was to measure the association between preconception care and the odds of severe maternal morbidity among women with Medicaid. STUDY DESIGN This is a secondary analysis of Medicaid claims using the Medicaid Analytic Extract files (2010-2012). We used the International Classification of Diseases, Ninth Revision codes, published by the US Office of Population Affairs' Quality Family Planning program to define 7 domains of preconception care. The primary outcome was maternal death within 12 weeks of delivery or severe maternal morbidity during birth hospitalization, defined by the presence of any diagnosis or procedure on the severe maternal morbidity International Classification of Diseases, Ninth Revision code list from the Centers for Disease Control and Prevention. Because this list may overestimate severe maternal morbidity by counting any blood transfusion, our secondary outcome used the same code list but without transfusion. We reviewed care in the year before conception and used logistic regression to estimate the association between each domain and severe maternal morbidity for all births to women enrolled in Medicaid and aged 15 to 45 years with births during 2012. We performed a subgroup analysis for women with chronic disease (kidney disease, hypertension, or diabetes). RESULTS Severe maternal morbidity or death occurred in 26,285 births (1.74%) when including blood transfusions and 9,481 births (0.63%) when excluding transfusions. Receiving contraceptive services in the year before conception was associated with decreased odds of severe maternal morbidity (adjusted odds ratio, 0.92; 95% confidence interval, 0.88-0.95) and pregnancy test services were associated with increased odds (adjusted odds ratio, 1.08; 95% confidence interval, 1.01-1.14). In the primary analysis, no significant associations were observed for other preconception care domains. Among those women with at least 1 chronic disease, contraceptive care (adjusted odds ratio, 0.84; 95% confidence interval, 0.75-0.95) and routine physical or gynecologic exams (adjusted odds ratio, 0.79; 95% confidence interval, 0.71-0.88) were associated with decreased odds of severe maternal morbidity. Similar associations were found for severe maternal morbidity when excluding blood transfusion. CONCLUSIONS Contraceptive services in the year before conception and routine exams for women with chronic disease are associated with decreased odds of severe maternal morbidity or death for Medicaid enrollees.

Abstract
BACKGROUND A recently developed obstetrical comorbidity scoring system enables the comparison of severe maternal morbidity rates independent of health status at the time of birth hospitalization. However, the scoring system has not been evaluated in racial-ethnic and socioeconomic groups or used to assess disparities in severe maternal morbidity. OBJECTIVE This study aimed to evaluate the performance of an obstetrical comorbidity scoring system when applied across racial-ethnic and socioeconomic groups and to determine the effect of comorbidity score risk adjustment on disparities in severe maternal morbidity. STUDY DESIGN We analyzed a population-based cohort of live births that occurred in California during 2011 through 2017 with linked birth certificates and birth hospitalization discharge data (n=3,308,554). We updated a previously developed comorbidity scoring system to include the International Classification of Diseases, Ninth and Tenth Revisions, Clinical Modifications diagnosis codes and applied the scoring system to subpopulations (groups) defined by race-ethnicity, nativity, payment method, and educational attainment. We then calculated the risk-adjusted rates of severe maternal morbidity (including and excluding blood transfusion-only cases) for each group and estimated the disparities for these outcomes before and after adjustment for the comorbidity score using logistic regression. RESULTS The obstetric comorbidity scores performed consistently across groups (C-statistics ranged from 0.68 to 0.76; calibration curves demonstrated overall excellent prediction of absolute risk). All non-White groups had significantly elevated rates of severe maternal morbidity before and after risk adjustment for comorbidities when compared with the White group (1.3% before, 1.3% after) (American Indian-Alaska Native: 2.1% before, 1.8% after; Asian: 1.5% before, 1.7% after; Black: 2.5% before, 2.0% after; Latinx: 1.6% before, 1.7% after; Pacific Islander: 2.2% before, 1.9% after; and multi-race groups: 1.7% before, 1.6% after). Risk adjustment also modestly increased disparities for the foreign-born group and government insurance groups. Higher educational attainment was associated with decreased severe maternal morbidity rates, which was largely unaffected by comorbidity risk adjustment. The pattern of results was the same whether or not transfusion-only cases were included as severe maternal morbidity. CONCLUSION These results support the use of an updated comorbidity scoring system to assess disparities in severe maternal morbidity. Disparities in severe maternal morbidity decreased in magnitude for some racial-ethnic and socioeconomic groups and increased in magnitude for other groups after adjustment for the comorbidity score.

Abstract
Objective: To evaluate whether patient-prescriber racial and ethnic concordance is associated with postpartum opioid prescribing patterns and patient-reported pain scores. Methods This is a retrospective cohort study of patients who delivered at a tertiary care center between December 1, 2015 and November 30, 2016. Self-identified non-Hispanic white (NHW), non-Hispanic black (NHB), Hispanic, or Asian patients were included. Patient-prescriber pairs were categorized as racially and ethnically concordant if they shared the same racial and ethnic identity; the prescriber was defined as the obstetrical provider who was responsible for the postpartum discharge of the patient. Multivariable regression models controlling for demographic and clinical confounders were used to assess the relationship of patient-prescriber racial and ethnic concordance with receipt of an opioid prescription and patient-reported pain score at discharge. Results Of 10,242 patients included in this analysis, 62.3% identified as NHW, 19.1% Hispanic, 9.7% NHB, and 8.9% Asian. About half (52.8%) of patients were discharged by a racially and ethnically concordant prescriber. Patient-prescriber racial and ethnic concordance was not associated with receipt of an opioid prescription (adjusted odds ratio [aOR] 0.82, confidence interval [95% CI] 0.67–1.00) or reporting a pain score ≥5 (aOR 0.90, 95% CI 0.69–1.16). However, NHB and Hispanic patients were less likely to receive an opioid prescription (aOR 0.73, 95% CI 0.56–0.95; aOR 0.73, 95% CI 0.57–0.92, respectively) and significantly more likely to report a pain score ≥5 (aOR 2.13, 95% CI 1.51–3.00; aOR 1.48 95% CI 1.08–2.01, respectively) than NHW patients, even when accounting for concordance. Conclusion Disparities in postpartum opioid prescribing and pain perception are not ameliorated by patient-prescriber racial and ethnic concordance.

Abstract
OBJECTIVE To determine the burden of perinatal morbidity among mothers of medically fragile infants. STUDY DESIGN We conducted a retrospective cohort study of 6849 mothers who delivered liveborn infants at a quaternary care hospital during a two-year period. We compared mothers of well babies with mothers of infants admitted to the Neonatal Intensive Care Unit (NICU), and we used logistic regression to model predictors of postpartum acute care utilization among NICU mothers. RESULTS Rates of obstetric morbidity were highest for mothers of infants staying ≥72 h in the NICU; 54.2% underwent cesarean birth, 7.5% experienced severe maternal morbidity, and 6.6% required a blood transfusion. Factors independently associated with postpartum acute care use included gestational age <28 weeks, ever smoking, non-Hispanic Black race, temperature >38 °C and receiving psychiatric medication during the birth hospitalization. CONCLUSION Focused support for mothers of NICU infants has the potential to reduce maternal morbidity and improve health.

Abstract
INTRODUCTION Our objective was to assess the association between the nurse providing bedside care and women's postpartum opioid use. METHODS Retrospective study of all women who birthed at a single center (December 2015 to November 2016). Patient, prescriber, and clinical data were abstracted. The postpartum nurse and total opioid use during the first 12-hour postpartum shift after birth were determined. A high amount of opioid use was defined as morphine milligram equivalents greater than or equal to 90% for this population (stratified by vaginal and cesarean births). A logistic regression model was fit with covariates entered in a step-wise manner to identify the extent to which individual nurses were associated with a greater likelihood of high opioid use by establishing one model in which the only covariate was nurse (model 1) and assessing whether the addition of patient (model 2), birth (model 3), and prescriber factors (model 4) altered the association. Kendall rank correlation assessed rank changes between models. RESULTS Of the 8376 and 2957 women who had vaginal and cesarean births, 17.9% and 10.2%, respectively, had high opioid use. In the vaginal cohort, women cared for by 46 of 200 nurses were significantly less likely to have high opioid use. Following adjustment, patients cared for by 53 of 200 bedside nurses (model 4) had significantly lower odds of having high opioid use. The rank order of nurses, with respect to the likelihood of opioid use, remained similar after adjustment for patient, birth, and prescriber factors (Τ = 0.84). Findings were similar for the cesarean cohort: 35 of 113 nurses were associated with a significantly lower likelihood of their patients having high opioid use, and the rank order remained similar after covariate adjustment (Τ = 0.78). DISCUSSION There is significant variation in postpartum women's opioid use based on the nurse that is not explained by patient, birth, or prescriber factors.

Abstract
OBJECTIVES Severe Maternal Morbidity (SMM) is a group of pregnancy complications in which a woman nearly dies. Despite its increasing prevalence, little research has evaluated geographic patterns of SMM and the underlying social determinants that influence excess risk. This study examined the spatial clustering of SMM across South Carolina, US, and its associations with place-based social and environmental factors. METHODS Hospitalized deliveries from 2012 to 2017 were analyzed using Kulldorff's spatial scan statistic to locate areas with abnormally high rates of SMM. SMM patients inside and outside risk clusters were compared using Generalized Estimating Equations (GEE) to determine underlying individual and community-level risk factors. RESULTS GEE models revealed that the odds of living in a high-risk SMM21 (SMM including blood transfusions) cluster was 2.49 times higher among Black patients (p < .001) compared to those outside of a high-risk cluster. Women residing in a high-risk SMM20 (SMM excluding blood transfusions) cluster were 1.38 times more likely to experience the most number of extremely hot days and 1.70 times more likely to present with obesity than women in a low-risk SMM cluster (p < .001). CONCLUSIONS This study is the first to characterize the geographic clustering of SMM risk in the US. Our geospatial approach contributes a novel understanding to factors which influence SMM beyond patient-level characteristics and identifies the impact of hot ambient temperature on maternal morbidity. Findings address an important literature gap surrounding place-based risk factors by explaining the contextual social and built environmental factors that drive SMM risk.

Abstract
Objectives Among childbearing women, insurance coverage determines degree of access to preventive and emergency care for maternal and infant health. Maternal-infant dyads with dual burden of severe maternal morbidity and preterm birth experience high physical and psychological morbidity, and the risk of dual burden varies by insurance type. We examined whether sociodemographic and perinatal risk factors of dual burden differed by insurance type. Methods We estimated relative risks of dual burden by maternal sociodemographic and perinatal characteristics in the 2007–2012 California birth cohort dataset stratified by insurance type and compared effects across insurance types using Wald Z-statistics. Results Dual burden ranged from 0.36% of privately insured births to 0.41% of uninsured births. Obstetric comorbidities, multiple gestation, parity, and birth mode conferred the largest risks across all insurance types, but effect magnitude differed. The adjusted relative risk of dual burden associated with preeclampsia superimposed on preexisting hypertension ranged from 9.1 (95% CI 7.6–10.9) for privately insured to 15.9 (95% CI 9.1–27.6) among uninsured. The adjusted relative risk of dual burden associated with cesarean birth ranged from 3.1 (95% CI 2.7–3.5) for women with Medi-Cal to 5.4 (95% CI 3.5–8.2) for women with other insurance among primiparas, and 7.0 (95% CI 6.0–8.3) to 19.4 (95% CI 10.3–36.3), respectively, among multiparas. Conclusions Risk factors of dual burden differed by insurance type across sociodemographic and perinatal factors, suggesting that care quality may differ by insurance type. Attention to peripartum care access and care quality provided by insurance type is needed to improve maternal and neonatal health.

Abstract
OBJECTIVE Induction of labor is known to be safe and highly effective in low-risk women. However, only limited research considers the relative success rates of induction of labor among women with one or more obstetric comorbidities. Our objective was to determine if the risk of cesarean delivery after induction of labor (IOL) is increased in women with a spectrum of hypertensive disorders of pregnancy compared to women with normotensive pregnancies. STUDY DESIGN We analyzed data from 1842 women undergoing IOL occurring at Grady Memorial Hospital in Atlanta, Georgia 2016-2018. We used multivariable log binomial models to estimate unadjusted and adjusted risk ratios (aRR) describing the association between hypertensive disorder diagnosis (preeclampsia with or without severe features, gestational hypertension, and chronic hypertension) and cesarean delivery, adjusting for demographics, pre-pregnancy conditions, and gestational age at delivery. RESULTS Overall, 44% (n = 808) of women in our study were diagnosed with any hypertensive disorder. Among women with hypertensive disorders, 74% had a successful vaginal delivery after IOL as compared to 82% of women without a hypertensive disorder. In the fully adjusted model, women with preeclampsia with severe features (aRR: 1.6, 95% CI: (1.3, 2.0)) and chronic hypertension had the largest risk for cesarean delivery (aRR 1.3, 95% CI: 0.9, 1.7)) compared with women with a normotensive pregnancy. CONCLUSION Our study suggests that while patients with certain hypertensive diagnoses may be at increased risk for cesarean delivery following IOL, most patients with hypertensive disorders were still able to undergo a successful vaginal delivery following IOL.

Abstract
BACKGROUND Understanding maternal morbidity and its determinants can help identify opportunities to prevent obstetric complications and improvements for maternal health. This study was conducted to determine the prevalence of severe maternal morbidity (SMM) and the associated factors. METHODS A hospital-based cross-sectional study was conducted at Koshi Hospital, Nepal, from January to March 2020. All women who met the inclusion criteria of age ≥18 years of age, Morang residents of Nepalese nationality, had received routine antenatal care, and given birth at Koshi Hospital were recruited consecutively. The World Health Organization criteria were used to identify the women with SMM. A multiple logistic regression analysis was performed. Overall, 346 women were recruited. FINDINGS The prevalence of SMM was 6.6%. Among the SMM cases, the most frequently occurring SMM conditions were hypertensive disorders (12, 56.5%), hemorrhagic disorders (6, 26.1%), and severe management indicators (8, 34.8%). Women with no or primary education (adjusted odds ratio: 0.10, 95% confidence interval: 0.01, 0.76) decreased the odds of SMM compared to secondary education. CONCLUSION The approximately 7% prevalence of SMM correlated with global studies. Maternal education was significantly associated with SMM. If referral hospitals were aware of the expected prevalence of potentially life-threatening maternal conditions, they could plan to avert future reproductive complications.

Abstract
Severe maternal morbidity (SMM) affects 50,000 women annually in the United States, but its consequences are not well understood. We aimed to estimate the association between SMM and risk of adverse cardiovascular events during the 2 years postpartum. We analyzed 137,140 deliveries covered by the Pennsylvania Medicaid program (2016-2018), weighted with inverse probability of censoring weights to account for nonrandom loss to follow-up. SMM was defined as any diagnosis on the Centers for Disease Control and Prevention list of SMM diagnoses and procedures and/or intensive care unit admission occurring at any point from conception through 42 days postdelivery. Outcomes included heart failure, ischemic heart disease, and stroke/transient ischemic attack up to 2 years postpartum. We used marginal standardization to estimate average treatment effects. We found that SMM was associated with increased risk of each adverse cardiovascular event across the follow-up period. Per 1,000 deliveries, relative to no SMM, SMM was associated with 12.1 (95% confidence interval (CI): 6.2, 18.0) excess cases of heart failure, 6.4 (95% CI: 1.7, 11.2) excess cases of ischemic heart disease, and 8.2 (95% CI: 3.2, 13.1) excess cases of stroke/transient ischemic attack at 26 months of follow-up. These results suggest that SMM identifies a group of women who are at high risk of adverse cardiovascular events after delivery. Women who survive SMM may benefit from more comprehensive postpartum care linked to well-woman care.

Abstract
Background: The most common reason for hospitalization in the United States is childbirth. The costs of childbirth are substantial. Materials and Methods: This was a retrospective cohort study of hospital deliveries identified in the MarketScan® Commercial and Medicaid health insurance claim databases. Women with an inpatient birth in the calendar year 2016 were included. Severe maternal morbidity (SMM) was identified using the Centers for Disease Control and Prevention algorithm of 21 International Classification of Diseases-10 codes. Mean costs and cost ratios for women with and without SMM were reported. Generalized linear models were used to analyze demographic and clinical variables influencing delivery costs. Results: We identified 1,486 women in the Commercial population, who had a birth in 2016 and met the criteria for SMM. The total mean per-patient costs of care for women with and without SMM were $50,212 and $23,795, respectively. In the Medicaid population there were 29,763 births, of which 342 met the criteria for SMM. The total mean per-patient costs of care for women with and without SMM were $26,513 and $9,652, respectively. A multifetal gestation, a cesarean delivery, maternal age, and pregnancy-related complications were independently predictive of increased delivery costs in both Commercial and Medicaid populations. Conclusions: The occurrence of SMM was associated with an increase in maternity-related costs of 111% in the Commercial and 175% in the Medicaid population. Some of the factors associated with increased delivery hospitalization costs could be treated or avoided.

Abstract
OBJECTIVE Hemorrhage is a major cause of maternal morbidity and mortality prompting creation of innovative risk assessment tools to identify patients at highest risk. We aimed to investigate the association of hemorrhage risk assessment with maternal morbidity and to evaluate maternal outcomes after implementation of the risk assessment across hospital sites. STUDY DESIGN We conducted a retrospective cohort analysis of a multicenter database including women admitted to labor and delivery from January 2015 to June 2018. The Association of Women's Health, Obstetric and Neonatal Nurses risk assessment tool was used to categorize patients as low, medium, or high risk for hemorrhage. Multivariate logistic regression was used to describe the association between hemorrhage risk score and markers of maternal morbidity and evaluate maternal outcomes before and after standardized implementations of the risk assessment tool. RESULTS In this study, 14,861 women were categorized as low risk (26%), 26,080 (46%) moderate risk, and 15,730 (28%) high risk (N = 56,671 births). For women with high-risk scores, the relative risk (RR) ratio compared with low-risk women was 4.9 (RR: 95% confidence interval [CI]: 3.2-7.4) for blood transfusion and 5.2 (RR: 95% CI: 4.6-5.9) for estimated blood loss (EBL) ≥ 1,000 mL. For the second objective, 110,633 women were available for pre- and postimplementation analyses (39,027 and 71,606, respectively). A 20% reduction in rates of blood transfusion (0.5-0.4%, p = 0.02) and EBL ≥ 1,000 mL (6.3-5.9%, p = 0.014) was observed between pre- and postimplementations of the admission hemorrhage risk assessment tool. CONCLUSION Women who were deemed high risk for hemorrhage using a hemorrhage risk assessment tool had five times higher risk for blood transfusion and EBL ≥ 1,000 mL compared with low-risk women. Given the low incidence of the outcomes explored, the hemorrhage risk assessment works moderately well to identify patients at risk for peripartum morbidity. KEY POINTS · This study aimed to understand the utility of the AWOHNN hemorrhage risk assessment tool for predicting hemorrhage-related morbidity and to evaluate maternal outcomes before and after tool implementations.. · A high score using a hemorrhage risk assessment tool on admission is associated with five times higher risk for blood transfusion and/or estimated blood loss ≥ 1,000 mL, compared with a low score.. · Use of a hemorrhage risk assessment tool works moderately well to identify patients at highest risk for hemorrhage-related morbidity..
