RESUMEN
IMPORTANCE: Hypertension is increasingly common in pregnancy capable individuals, yet there is limited data on antihypertensive medication dispensation in peripartum individuals. OBJECTIVE: To describe antihypertensive medication dispensation from preconception through the first year postpartum. DESIGN, SETTING, AND PARTICIPANTS: This retrospective cohort study used the Truven Health MarketScan administrative data from 2008 through 2014 to identify women in the United States with commercial or government health insurance, aged 15-54, free from heart disease, who experienced a pregnancy and filled at least one prescription for an antihypertensive medication between three months prior to conception and 12 months after the end of the pregnancy. MAIN OUTCOMES AND MEASURES: We describe antihypertensive dispensation patterns (continuation, initiation, and discontinuation) by medication class during five time periods: preconception, first, second, and third trimesters, and the first year postpartum. RESULTS: Of 1,058,521 pregnancies, 108,614 (10.3%) were exposed to at least one antihypertensive medication dispensation. The most commonly dispensed medications across all periods combined were adrenergic blockers, calcium channel blockers (CCBs), and diuretics. Renin-angiotensin-aldosterone system (RAAS) inhibitors were the third most dispensed medication class in the preconception period (26.4%), and fills decreased to 5.7% and 1.7% in the second and third trimesters, respectively. Of the women with chronic hypertension who filled at least one prescription prior to conception, 8.4% were not dispensed an antihypertensive medication during the first year after delivery. CONCLUSIONS AND RELEVANCE: Antihypertensive prescription dispensation of both preferred and potentially harmful agents is common in pregnancy capable individuals. Patterns of dispensation suggest room for improvement in the treatment of chronic hypertension after a pregnancy.
RESUMEN
OBJECTIVE: To characterize national trends in expedited postpartum discharge and, secondarily, to identify predictors of expedited postpartum discharge and assess whether expedited postpartum discharge was associated with postpartum readmissions within 60 days of delivery hospitalization discharge. METHODS: Birth hospitalizations and subsequent 60-day postpartum readmissions were extracted from the 2016-2020 Nationwide Readmissions Database for this retrospective cohort study. Postpartum discharge was categorized as expedited (less than 2 days after vaginal birth or less than 3 days after cesarean birth), routine (2 days after vaginal birth or 3 days after cesarean birth), or prolonged (more than 2 days after vaginal birth or more than 3 days after cesarean birth). Trends in expedited discharge were assessed over the study period with joinpoint regression. Unadjusted and adjusted logistic regression models were performed to assess clinical, hospital, and demographic predictors of expedited postpartum discharge. Sixty-day postpartum readmission risk was calculated, and adjusted regression models were performed to evaluate the association between expedited postpartum discharge and readmission. RESULTS: Of 17.9 million birth hospitalizations, 32.9% had expedited postpartum discharge. The overall 60-day postpartum readmission rate after delivery hospitalization discharge was 1.7% for all patients, 1.4% for expedited postpartum discharge, 1.6% for routine discharge, and 3.3% for prolonged discharge. Rates of expedited postpartum increased from 29.1% in 2016 to 31.4% in 2019 and to 43.8% in 2020. This trend was not significant (average annual percent change: 9.9%, 95% CI, -1.6% to 23.7%), although rates of expedited discharge were significantly higher in 2020 than in 2016-2019 ( P <.01). Younger and older age, chronic comorbid conditions, mental health conditions, and obstetric complications (eg, transfusion, chorioamnionitis or endometritis) were associated with lower likelihood of expedited postpartum discharge. Expedited postpartum discharge was associated with 14% lower adjusted odds of 60-day postpartum readmission compared with routine discharge (adjusted odds ratio 0.86, 95% CI, 0.85-0.88). CONCLUSION: Rates of expedited postpartum discharge increased significantly in 2020 compared with 2016-2019 and were not associated with 60-day postpartum readmission. These findings suggest that broader use of expedited postpartum discharge has not resulted in increased risk of postpartum readmissions.

OBJECTIVE: To assess the frequency of, risk factors for, and adverse outcomes associated with diabetic ketoacidosis (DKA) at delivery hospitalization among individuals with pregestational diabetes (type 1 and 2 diabetes mellitus) and secondarily to evaluate the frequency of and risk factors for antepartum and postpartum hospitalizations for DKA. METHODS: We conducted a serial, cross-sectional study using the Agency for Healthcare Research and Quality's Healthcare Cost and Utilization Project Nationwide Readmissions Database from 2010 to 2020 of pregnant individuals with pregestational diabetes hospitalized for delivery. The exposures were 1) sociodemographic and clinical risk factors for DKA and 2) DKA. The outcomes were DKA at delivery hospitalization, maternal morbidity (nontransfusion severe maternal morbidity (SMM), critical care procedures, cardiac complications, acute renal failure, and transfusion), and adverse pregnancy outcomes (preterm birth, hypertensive disorders of pregnancy, and cesarean delivery) and secondarily DKA at antepartum and postpartum hospitalizations. RESULTS: Of 392,796 deliveries in individuals with pregestational diabetes (27.2% type 1 diabetes, 72.8% type 2 diabetes), there were 4,778 cases of DKA at delivery hospitalization (89.1% type 1 diabetes, 10.9% type 2 diabetes). The frequency of DKA at delivery hospitalization was 1.2% (4.0% with type 1 diabetes, 0.2% with type 2 diabetes), and the mean annual percentage change was 10.8% (95% CI, 8.2-13.2%). Diabetic ketoacidosis at delivery hospitalization was significantly more likely among those who had type 1 diabetes compared with those with type 2 diabetes, who were younger in age, who delivered at larger and metropolitan hospitals, and who had Medicaid insurance, lower income, multiple gestations, and prior psychiatric illness. Diabetic ketoacidosis during the delivery hospitalization was associated with an increased risk of nontransfusion SMM (20.8% vs 2.4%, adjusted odds ratio [aOR] 8.18, 95% CI, 7.20-9.29), critical care procedures (7.3% vs 0.4%, aOR 15.83, 95% CI, 12.59-19.90), cardiac complications (7.8% vs 0.8%, aOR 8.87, 95% CI, 7.32-10.76), acute renal failure (12.3% vs 0.7%, aOR 9.78, 95% CI, 8.16-11.72), and transfusion (6.2% vs 2.2%, aOR 2.27, 95% CI, 1.87-2.75), as well as preterm birth (31.9% vs 13.5%, aOR 2.41, 95% CI, 2.17-2.69) and hypertensive disorders of pregnancy (37.4% vs 28.1%, aOR 1.11, 95% CI, 1.00-1.23). In secondary analyses, the overall frequency of antepartum DKA was 3.1%, and the mean annual percentage change was 4.1% (95% CI, 0.3-8.6%); the overall frequency of postpartum DKA was 0.4%, and the mean annual percentage change was 3.5% (95% CI, -1.6% to 9.6%). Of 3,092 antepartum hospitalizations among individuals with DKA, 15.7% (n=485) had a recurrent case of DKA at delivery hospitalization. Of 1,419 postpartum hospitalizations among individuals with DKA, 20.0% (n=285) previously had DKA at delivery hospitalization. The above risk factors for DKA at delivery hospitalization were similar for DKA at antepartum and postpartum hospitalizations. CONCLUSION: The frequency of DKA at delivery hospitalization and antepartum hospitalizations for DKA increased between 2010 and 2020 among deliveries in individuals with pregestational diabetes in the United States. Diabetic ketoacidosis is associated with an increased risk of maternal morbidity and adverse pregnancy outcomes. Risk factors for DKA at delivery were similar to those for DKA during the antepartum and postpartum periods.
RESUMEN
BACKGROUND: Peripartum cardiomyopathy (PPCM), a form of heart failure with reduced ejection fraction (HFrEF) that occurs during the final month of pregnancy through the first 5 months postpartum, is associated with heightened risk for maternal morbidity and mortality. Stroke is a common complication of HFrEF but there is limited data on the incidence of stroke in PPCM. METHODS: Using statewide, nonfederal administrative data from 2000 to 2015, we analyzed age-adjusted risk of stroke within 3 years after PPCM-associated pregnancies. RESULTS: PPCM was associated with a greater than 4-fold increased risk of pregnancy-related stroke (aHR 4.7, 95% CI: 3.0-7.5). This risk was highest at the time of PPCM diagnosis but remained elevated in the first postpartum year. CONCLUSION: Our findings confirm the strong association between PPCM and stroke, with risk that persists throughout and after the peripartum period.

OBJECTIVE: To analyse trends, risk factors and adverse outcomes associated with antenatal pyelonephritis hospitalisations. DESIGN: Retrospective cohort. SETTING: A national sample of US delivery hospitalisations with associated antenatal hospitalisations. POPULATION: US delivery hospitalisations in the Nationwide Readmissions Database from 2010 to 2020. METHODS: Antenatal hospitalisations with a pyelonephritis diagnosis within the 9 months before delivery hospitalisation were analysed. Clinical, demographic and hospital risk factors associated with antenatal pyelonephritis hospitalisations were analysed with unadjusted and adjusted logistic regression models with unadjusted and adjusted odds ratios as measures of effect. Temporal trends in antenatal pyelonephritis hospitalisations were analysed with Joinpoint regression to determine the relative measure of average annual percent change (AAPC). Risk for severe maternal morbidity and sepsis during antenatal pyelonephritis hospitalisations was similarly analysed with Joinpoint regression. RESULTS: Of an estimated 10.2 million delivery hospitalisations, 49 140 (0.48%) had an associated antenatal pyelonephritis hospitalisation. The proportion of deliveries with a preceding antenatal pyelonephritis hospitalisation decreased by 29% from 0.56% in 2010 to 0.40% in 2020 (AAPC -2.9%, 95% CI -4.0% to -1.9%). Antenatal pyelonephritis decreased, but risk for sepsis diagnoses increased during these hospitalisations from 3.7% in 2010 to 18.0% in 2020 (AAPC 17.2%, 95% CI 14.2%-21.1%). Similarly, risk for severe morbidity increased from 2.6% in 2010 to 4.4% in 2020 (AAPC 5.5%, 95% CI 0.8%-10.7%). CONCLUSION: Antenatal pyelonephritis admissions appear to be decreasing in the USA. However, these hospitalisations are associated with a rising risk for sepsis and severe maternal morbidity.
RESUMEN
OBJECTIVE: To assess (i) clinical and pregnancy characteristics, (ii) patterns of surgical procedures, and (iii) surgical morbidity associated with cesarean hysterectomy for placenta accreta spectrum based on the specialty of the attending surgeon. METHODS: The Premier Healthcare Database was queried retrospectively to study patients with placenta accreta spectrum who underwent cesarean delivery and concurrent hysterectomy from 2016 to 2020. Surgical morbidity was assessed with propensity score inverse probability of treatment weighting based on surgeon specialty for hysterectomy: general obstetrician-gynecologists, maternal-fetal medicine specialists, and gynecologic oncologists. RESULTS: A total of 2240 cesarean hysterectomies were studies. The most common surgeon type was general obstetrician-gynecologist (n = 1534, 68.5%), followed by gynecologic oncologist (n = 532, 23.8%) and maternal-fetal medicine specialist (n = 174, 7.8%). Patients in the gynecologic oncologist group had the highest rate of placenta increta or percreta, followed by the maternal-fetal medicine specialist and general obstetrician-gynecologist groups (43.4%, 39.6%, and 30.6%, P < .001). In a propensity score-weighted model, measured surgical morbidity was similar across the three subspecialty groups, including hemorrhage / blood transfusion (59.4-63.7%), bladder injury (18.3-24.0%), ureteral injury (2.2-4.3%), shock (8.6-10.5%), and coagulopathy (3.3-7.4%) (all, P > .05). Among the cesarean hysterectomy performed by gynecologic oncologist, hemorrhage / transfusion rates remained substantial despite additional surgical procedures: tranexamic acid / ureteral stent (60.4%), tranexamic acid / endo-arterial procedure (76.2%), ureteral stent / endo-arterial procedure (51.6%), and all three procedures (55.4%). Tranexamic acid administration with ureteral stent placement was associated with decreased bladder injury (12.8% vs 23.8-32.2%, P < .001). CONCLUSION: These data suggest that patient characteristics and surgical procedures related to cesarean hysterectomy for placenta accreta spectrum differ based on surgeon specialty. Gynecologic oncologists appear to manage more severe forms of placenta accreta spectrum. Regardless of surgeon's specialty, surgical morbidity of cesarean hysterectomy for placenta accreta spectrum is significant.

OBJECTIVE: To evaluate risk for adverse obstetric outcomes associated with the coronavirus disease 2019 (COVID-19) pandemic period and with COVID-19 diagnoses. DESIGN: Serial cross-sectional study. SETTING: A national sample of US delivery hospitalisations before (1/2016 to 2/2020) and during the first 10 months of (3/2020 to 12/2020) the COVID-19 pandemic. POPULATION: All 2016-2020 US delivery hospitalisations in the National Inpatient Sample. METHODS: Delivery hospitalisations were identified and stratified into pre-pandemic and pandemic periods and the likelihood of adverse obstetric outcomes was compared using logistic regression models with adjusted odds ratios (aOR) with 95% confidence intervals (CI) as measures of association. Risk for adverse outcomes was also analysed specifically for 2020 deliveries with a COVID-19 diagnosis. MAIN OUTCOME MEASURE: Adverse maternal outcomes including respiratory complications and cardiac morbidity. RESULTS: Of an estimated 18.2 million deliveries, 2.9 million occurred during the pandemic. The proportion of delivery hospitalisations with a COVID-19 diagnosis increased from 0.1% in March 2020 to 3.1% in December. Comparing the pandemic period to the pre-pandemic period, there were higher adjusted odds of transfusion (aOR 1.12, 95% CI 1.05-1.19), a respiratory complication composite (aOR 1.37, 95% CI 1.29-1.46), cardiac severe maternal morbidity (aOR 1.30, 95% 1.20-1.39), postpartum haemorrhage (aOR 1.19, 95% CI 1.15-1.24), placental abruption/antepartum haemorrhage (OR 1.04, 95% CI 1.00-1.08), and hypertensive disorders of pregnancy (OR 1.23, 95% CI 1.21-1.26). These associations were similar to unadjusted analysis. Risk for these outcomes during the pandemic period was significantly higher in the presence of a COVID-19 diagnosis. CONCLUSIONS: In a national estimate of delivery hospitalisations, the odds of cardiac and respiratory outcomes were higher in 2020 compared with 2016-2019. COVID-19 diagnoses were specifically associated with a range of serious complications.

OBJECTIVE: This study aimed to evaluate trends, risk factors, and outcomes associated with infections and sepsis during delivery hospitalizations in the United States. STUDY DESIGN: The 2000-2020 National Inpatient Sample was used for this repeated cross-sectional analysis. Delivery hospitalizations of patients aged 15 to 54 with and without infection and sepsis were identified. Common infection diagnoses during delivery hospitalizations analyzed included (i) pyelonephritis, (ii) pneumonia/influenza, (iii) endometritis, (iv) cholecystitis, (v) chorioamnionitis, and (vi) wound infection. Temporal trends in sepsis and infection during delivery hospitalizations were analyzed. The associations between sepsis and infection and common chronic health conditions including asthma, chronic hypertension, pregestational diabetes, and obesity were analyzed. The associations between clinical, demographic, and hospital characteristics, and infection and sepsis were determined with unadjusted and adjusted logistic regression models with unadjusted odds ratio (OR) and adjusted odds ratios with 95% confidence intervals as measures of association. RESULTS: An estimated 80,158,622 delivery hospitalizations were identified and included in the analysis, of which 2,766,947 (3.5%) had an infection diagnosis and 32,614 had a sepsis diagnosis (4.1 per 10,000). The most common infection diagnosis was chorioamnionitis (2.7% of deliveries) followed by endometritis (0.4%), and wound infections (0.3%). Infection and sepsis were more common in the setting of chronic health conditions. Evaluating trends in individual infection diagnoses, endometritis and wound infection decreased over the study period both for patients with and without chronic conditions, while risk for pyelonephritis and pneumonia/influenza increased. Sepsis increased over the study period for deliveries with and without chronic condition diagnoses. Risks for adverse outcomes including mortality, severe maternal morbidity, the critical care composite, and acute renal failure were all significantly increased in the presence of sepsis and infection. CONCLUSION: Endometritis and wound infections decreased over the study period while risk for sepsis increased. Infection and sepsis were associated with chronic health conditions and accounted for a significant proportion of adverse obstetric outcomes including severe maternal morbidity. KEY POINTS: · Sepsis increased over the study period for deliveries with and without chronic condition diagnoses.. · Endometritis and wound infection decreased over the study period.. · Infection and sepsis accounted for a significant proportion of adverse obstetric outcomes..
RESUMEN
OBJECTIVE: Gastroschisis is a full-thickness congenital defect of the abdominal wall through which intestines and other organs may herniate. In a prior analysis, attempted vaginal delivery with fetal gastroschisis appeared to increase through 2013, although cesarean delivery remained common. The objective of this analysis was to update current trends in attempted vaginal birth among pregnancies complicated by gastroschisis. STUDY DESIGN: We performed an updated cross-sectional analysis of live births from 2014 and 2020 using data from the U.S. National Vital Statistics System and evaluated trends in attempted vaginal deliveries among births with gastroschisis. Trends were evaluated using joinpoint regression. We constructed logistic regression models to evaluate the association between demographic and clinical variables and attempted vaginal delivery in the setting of gastroschisis. RESULTS: Among 5,355 deliveries with gastroschisis meeting inclusion criteria, attempted vaginal delivery increased significantly from 68.9% to 75.1%, an average annual percent change of 1.7% (95% confidence interval [CI], 0.8-2.5). Among gastroschisis-complicated pregnancies, patients 35 to 39 years old (adjusted odds ratio [aOR], 0.53; 95% CI, 0.37-0.79) and Hispanic race/ethnicity (aOR, 0.69; 95% CI, 0.58-0.62) were at lower likelihood of attempted vaginal delivery in adjusted analyses. CONCLUSION: These findings suggest that vaginal delivery continues to increase in the setting of gastroschisis. Further reduction of surgical delivery for this fetal defect may be possible. KEY POINTS: · Vaginal deliveries increased among gastroschisis pregnancies.. · Hispanic patients were less likely to attempt vaginal delivery.. · Some gastroschisis pregnancies still deliver surgically..

OBJECTIVE: To assess trends and outcomes associated with systemic lupus erythematosus (SLE) and antiphospholipid syndrome (APS) during US delivery hospitalizations. STUDY DESIGN: The National Inpatient Sample from 2000 to 2019 was used for this repeated cross-sectional analysis. We identified delivery hospitalizations with and without SLE. Temporal trends in SLE during delivery hospitalizations were determined using joinpoint regression. Adjusted logistic regression models accounting for demographic, clinical, and hospital factors were used to determine adjusted odds ratios (aORs) for adverse outcomes based on the presence or absence of SLE. RESULTS: Of an estimated 76 698 775 delivery hospitalizations identified in the NIS, 79386 (0.10%) had an associated diagnosis of SLE. Over the study period, SLE increased from 6.7 to 14.6 cases per 10 000 delivery hospitalizations (average annual percent change 4.5%, 95% CI 4.0-5.1). Deliveries with SLE had greater odds of non-transfusion severe morbidity (aOR 2.21, 95% CI 2.00, 2.44) and underwent a larger absolute increase in morbidity risk over the study period. SLE was associated with a range of other adverse outcomes including preterm delivery, eclampsia, cesarean delivery, and blood transfusion. CONCLUSION: The proportion of deliveries to women with SLE has increased over time in the US, and SLE and APS are associated with a broad range of adverse outcomes.

OBJECTIVES: Structural racism (SR) is viewed as a root cause of racial and ethnic disparities in maternal health outcomes. However, evidence linking SR to increased odds of severe adverse maternal outcomes (SAMO) is scant. This study assessed the association between state-level indicators of SR and SAMO during childbirth. METHODS: Data for non-Hispanic Black and non-Hispanic white women came from the US Natality file, 2017-2018. The exposures were state-level Black-to-white inequity ratios for lower education level, unemployment, and prison incarceration. The outcome was patient-level SAMO, including eclampsia, blood transfusion, hysterectomy, or intensive care unit admission. Adjusted odds ratios (aORs) of SAMO associated with each ratio were estimated using multilevel models adjusting for patient, hospital, and state characteristics. RESULTS: A total of 4,804,488 birth certificates were analyzed, with 22.5% for Black women. SAMO incidence was 106.4 per 10,000 (95% CI 104.5, 108.4) for Black women, and 72.7 per 10,000 (95% CI 71.8, 73.6) for white women. Odds of SAMO increased 35% per 1-unit increase in the unemployment ratio for Black women (aOR 1.35; 95% CI 1.04, 1.73), and 16% for white women (aOR 1.16; 95% CI 1.01, 1.33). Odds of SAMO increased 6% per 1-unit increase in the incarceration ratio for Black women (aOR 1.06; 95% CI 1.03, 1.10), and 4% for white women (aOR 1.04; 95% CI 1.02, 1.06). No significant association was observed between SAMO and the lower education level ratio. CONCLUSIONS FOR PRACTICE: State-level Black-to-white inequity ratios for unemployment and incarceration are associated with significantly increased odds of SAMO.

OBJECTIVE: To evaluate the prevalence, timing, clinical risk factors, and adverse outcomes associated with postpartum readmissions for maternal sepsis. METHODS: We conducted a retrospective cohort study of delivery hospitalizations and 60-day postpartum readmissions for females aged 15-54 years with and without sepsis using the 2016-2020 Nationwide Readmissions Database. Temporal trends in sepsis diagnoses during delivery hospitalizations and 60-day postpartum readmissions were analyzed with the National Cancer Institute's Joinpoint Regression Program to estimate the average annual percent change with 95% CIs. Logistic regression models were fit to determine whether delivery hospitalization characteristics were associated with postpartum sepsis readmissions, and unadjusted and adjusted odds ratios with 95% CIs were reported. Adverse outcomes associated with sepsis during delivery hospitalization and readmission were described, including death, severe morbidity, a critical care composite, and renal failure. RESULTS: Overall, 15,268,190 delivery hospitalizations and 256,216 associated 60-day readmissions were included after population weighting, of which 16,399 (1.1/1,000 delivery hospitalizations) had an associated diagnosis of sepsis at delivery, and 20,130 (1.3/1,000 delivery hospitalizations) had an associated diagnosis of sepsis with postpartum readmission. A sepsis diagnosis was present in 7.9% of all postpartum readmissions. Characteristics associated with postpartum sepsis readmission included younger age at delivery, Medicaid insurance, lowest median ZIP code income quartile, and chronic medical conditions such as obesity, pregestational diabetes, and chronic hypertension. Postpartum sepsis readmissions were associated with infection during the delivery hospitalization, including intra-amniotic infection or endometritis, wound infection, and delivery sepsis. Sepsis diagnoses were associated with 24.4% of maternal deaths at delivery and 38.4% postpartum, 2.2% cases of nontransfusion severe morbidity excluding sepsis at delivery and 13.6% postpartum, 15.6% of critical care composite diagnoses at delivery and 30.1% postpartum, and 11.1% of acute renal failure diagnoses at delivery and 36.4% postpartum. CONCLUSION: Sepsis accounts for a significant proportion of postpartum readmissions and is a major contributor to adverse outcomes during delivery hospitalizations and postpartum readmissions.

OBJECTIVE: To evaluate risk for peripartum cardiomyopathy during delivery and postpartum hospitalizations, and analyze associated trends, risk factors, and clinical outcomes. METHODS: The 2010-2020 Nationwide Readmissions Database was used for this retrospective cohort study. Delivery hospitalizations along with postpartum readmissions occurring within five months of delivery discharge were analyzed. Risk factors associated with peripartum cardiomyopathy were analyzed with unadjusted and adjusted logistic regression models with odds ratios as measures of effect. Risk for severe adverse outcomes associated with peripartum cardiomyopathy was analyzed. Trends were analyzed with joinpoint regression. RESULTS: Of 39,790,772 delivery hospitalizations identified, 9,210 were complicated by a diagnosis of peripartum cardiomyopathy (2.3 per 10,000). Risk for a 5-month readmission with a peripartum cardiomyopathy diagnosis was 4.8 per 10,000. Factors associated with peripartum cardiomyopathy during deliveries included preeclampsia with severe features (OR 18.9, 95 % CI 17.2, 20.7), preeclampsia without severe features (OR 6.9, 95 % CI 6.1, 7.8), multiple gestation (OR 4.7, 95 % CI 4.1, 5.3), chronic hypertension (OR 10.1, 95 % CI 8.9, 11.3), and older maternal age. Associations were attenuated but retained significance in adjusted models. Similar estimates were found when evaluating associations with postpartum readmissions. Peripartum cardiomyopathy readmissions were associated with 10 % of overall postpartum deaths, 21 % of cardiac arrest/ventricular fibrillation diagnoses, 18 % of extracorporeal membrane oxygenation cases, and 40 % of cardiogenic shock. In joinpoint analysis, peripartum cardiomyopathy increased significantly during delivery hospitalizations (average annual percent change [AAPC] 2.2 %, 95 % CI 1.0 %, 3.4 %) but not postpartum readmissions (AAPC 0.0 %, 95 % CI -1.6 %, 1.6 %). CONCLUSION: Risk for peripartum cardiomyopathy increased during delivery hospitalizations over the study period. Obstetric conditions such as preeclampsia and chronic medical conditions that are increasing in prevalence in the obstetric population were associated with the highest odds of peripartum cardiomyopathy.

OBJECTIVE: This study aimed to evaluate cesarean rates and risk for obstetric complications among deliveries with a history of prior uterine surgery. STUDY DESIGN: This serial cross-sectional study analyzed deliveries with and without prior uterine surgery in the 2016-2019 Nationwide Inpatient Sample. Unadjusted and adjusted logistic regression models were performed to assess risk of nontransfusion severe maternal morbidity (SMM) and other obstetric complications based on the presence or absence of prior uterine surgery with unadjusted and adjusted odds ratios (aORs) with 95% confidence intervals (CIs) as measures of association. Adjusted models accounted for demographic, hospital, and delivery factors. Demographics and clinical factors among deliveries with and without a prior history of uterine surgery diagnosis were compared with the chi-square test with p < 0.05 considered statistically significant. RESULTS: Of 14.7 million delivery hospitalization identified, 6,910 (4.7 per 10,000) had a history of uterine surgery and 111,710 (0.76%) experienced SMM. Women with prior uterine surgery were more likely to be older, to be of unknown race or ethnicity, and to have private insurance (p < 0.01 for all). Eighty-five percent of deliveries with prior uterine surgery were performed by cesarean compared with 32% of deliveries without prior uterine surgery (p < 0.01). In adjusted analysis, compared with patients without prior uterine surgery, patients with prior uterine surgery were not at increased risk for SMM (aOR 1.23, 95% CI 0.73-2.07). Evaluating obstetric complications, patients with prior uterine surgery had a decreased risk of postpartum hemorrhage (aOR 0.64, 95% CI 0.43-0.96) and an increased risk of peripartum hysterectomy (aOR 4.12, 95% CI 1.75-9.67), and no difference in other obstetric complications assessed. CONCLUSION: These findings suggest that current clinical practice results in similar delivery risks among patients with compared with without prior uterine surgery. KEY POINTS: · Risk for most adverse outcomes is similar among patients with prior uterine surgery.. · Risk for peripartum hysterectomy was higher with prior uterine surgery.. · Risk for SMM was not higher with prior uterine surgery..
RESUMEN
BACKGROUND: Although peripartum hysterectomy for placenta accreta spectrum disorder is known to be associated with complications at the time of delivery, there are limited data on postpartum outcomes and readmission risk in this population. OBJECTIVE: This study aimed to analyze risks for adverse outcomes and postpartum readmissions in the setting of peripartum hysterectomy for placenta accreta spectrum disorder by severity of placenta accreta spectrum disorder subcategory. STUDY DESIGN: Using the 2016-2020 Nationwide Readmissions Database, this retrospective cohort study identified peripartum hysterectomies with a diagnosis of placenta accreta spectrum disorder. The primary exposure was placenta accreta spectrum disorder, subcategorized as placenta accreta vs increta/percreta. The primary outcome was readmission rate and delivery complications. Complications evaluated included the following: (1) nontransfusion severe maternal morbidity (ntSMM), (2) venous thromboembolism, (3) reoperation, (4) intraoperative complications, (5) hemorrhage, (6) sepsis, and (7) surgical site complications. We additionally evaluated delivery hospitalization and readmission mean length of stay, and hospital costs. Unadjusted and adjusted logistic regression models were fit for outcomes adjusting for clinical, demographic, and hospital factors. The association measures were expressed as unadjusted and adjusted odds ratios with 95% confidence intervals. RESULTS: Between 2016 and 2020, 7864 hysterectomies during a delivery hospitalization with a diagnosis of placenta accreta spectrum disorder were identified (66.5% with placenta accreta and 33.5% with placenta increta/percreta diagnoses). The overall 60-day all-cause readmission rate was 7.3%. Most readmissions (57.2%) occurred within 10 days of hospital discharge. Compared with peripartum hysterectomy with a diagnosis of placenta accreta, hysterectomies with placenta increta/percreta diagnoses carried significantly increased risk of 60-day readmission (adjusted odds ratio, 1.31; 95% confidence interval, 1.01-1.71), inpatient mortality (odds ratio, 13.23; 95% confidence interval, 3.35-52.30), nontransfusion severe maternal morbidity (adjusted odds ratio, 1.43; 95% confidence interval, 1.20-1.71), intraoperative complications (adjusted odds ratio, 2.31; 95% confidence interval, 1.93-2.77), and surgical site complications (adjusted odds ratio, 1.55; 95% confidence interval, 1.23-1.95). The median length of stay during delivery hospitalization was longer for placenta increta/percreta (5.8 days; 95% confidence interval, 5.4-6.1) than for placenta accreta (4.2 days; 95% confidence interval, 4.1-4.3; P<.05). In addition, delivery hospitalization costs were higher in cases of placenta increta/percreta (median, $30,686; 95% confidence interval, $28,922-$32,449) than placenta accreta (median, $21,321; 95% confidence interval, $20,480-$22,163). CONCLUSION: Complication and readmission risks after peripartum hysterectomy with placenta accreta spectrum disorder are high. Compared with patients with placenta accreta, patients with placenta increta/percreta had increased risk for delivery and postoperative complications and postpartum readmission, and increased costs and length of stay.

OBJECTIVE: Given that updated estimates of Ehlers-Danlos syndrome and risks for obstetric complications including postpartum readmission may be of public health significance, we sought to analyze associated obstetric trends and outcomes in a nationally representative population. STUDY DESIGN: The 2016 to 2020 Nationwide Readmissions Database was used for this retrospective cohort study. Delivery hospitalizations to women aged 15 to 54 with and without Ehlers-Danlos syndrome were identified. Temporal trends in Ehlers-Danlos syndrome diagnoses during delivery hospitalizations were analyzed using joinpoint regression to estimate the average annual percent change with 95% confidence intervals (CIs). To determine whether adverse obstetric outcomes during the delivery were associated with Ehlers-Danlos syndrome, unadjusted and adjusted logistic regression models were fit with unadjusted (odds ratio [OR]) and adjusted ORs with 95% CIs as measures of association. In addition to analyzing adverse delivery outcomes, risk for 60-day postpartum readmission was analyzed. RESULTS: An estimated 18,214,542 delivery hospitalizations were included of which 7,378 (4.1 per 10,000) had an associated diagnosis of Ehlers-Danlos syndrome. Ehlers-Danlos syndrome diagnosis increased from 2.7 to 5.2 per 10,000 delivery hospitalization from 2016 to 2020 (average annual percent change increase of 16.1%, 95% CI: 9.4%, 23.1%). Ehlers-Danlos syndrome was associated with increased odds of nontransfusion severe maternal morbidity (OR: 1.84, 95% CI: 1.38, 2.45), cervical insufficiency (OR: 2.14, 95% CI: 1.46, 3.13), postpartum hemorrhage (OR: 1.41, 95% CI: 1.17, 1.68), cesarean delivery (OR: 1.26, 95% CI: 1.17, 1.36), and preterm delivery (OR: 1.35, 95% CI: 1.16, 1.56). Estimates for transfusion, placental abruption, and placenta previa did not differ significantly. Risk for 60-day postpartum readmission was 3.0% among deliveries with Ehlers-Danlos (OR: 1.76, 95% CI: 1.37, 2.25). CONCLUSION: Ehlers-Danlos syndrome diagnoses approximately doubled over the 5-year study period and was associated with a range of adverse obstetric outcomes and complications during delivery hospitalizations as well as risk for postpartum readmission. KEY POINTS: · Ehlers-Danlos syndrome diagnoses approximately doubled over the 5-year study period.. · Ehlers-Danlos was associated with a range of adverse obstetric outcomes.. · Ehlers-Danlos was associated with increased readmission risk..
RESUMEN
BACKGROUND: Labor neuraxial analgesia may reduce the odds of postpartum hemorrhage, the leading indication for maternal blood transfusion during childbirth. This study tested the hypothesis that labor neuraxial analgesia is associated with reduced odds of maternal blood transfusion overall. METHODS: U.S. birth certificate data in the Natality File of the National Vital Statistics System for all 50 states from 2015 to 2018 for vaginal and intrapartum cesarean deliveries were analyzed. The exposure was labor neuraxial analgesia. The primary outcome was maternal blood transfusion, recorded on the birth certificate, which has low sensitivity for this outcome. Adjusted odds ratios and 95% CIs of blood transfusion associated with neuraxial analgesia were estimated using propensity score matching. The adjusted odds ratios were estimated overall and according to delivery mode, and treatment effect was compared between vaginal and intrapartum cesarean deliveries using an interaction term. Sensitivity analyses were performed using inverse propensity score weighting and quantitative bias analysis for outcome misclassification. RESULTS: Of the 12,503,042 deliveries analyzed, 9,479,291 (75.82%) were with neuraxial analgesia, and 42,485 (0.34%) involved maternal blood transfusion. After propensity score matching, the incidence of blood transfusion was 0.30% in women without neuraxial analgesia (7,907 of 2,589,493) and 0.20% in women with neuraxial analgesia (5,225 of 2,589,493), yielding an adjusted odds ratio of 0.87 (95% CI, 0.82 to 0.91) overall. For intrapartum cesarean deliveries, the adjusted odds ratio was 0.55 (95% CI, 0.48 to 0.64), and for vaginal deliveries it was 0.93 (95% CI,. 0.88 to 0.98; P value for the interaction term < 0.001). The results were consistent in the sensitivity analyses, although the quantitative bias analysis demonstrated wide variation in potential effect size point estimates. CONCLUSIONS: Labor neuraxial analgesia may be associated with reduced odds of maternal blood transfusion in intrapartum cesarean deliveries and, to a lesser extent, vaginal deliveries. The specific effect size varies widely by delivery mode and is unclear given the poor sensitivity of the data set for the maternal transfusion primary outcome.

BACKGROUND: Eclampsia is an indicator of severe maternal morbidity and can be prevented through increased prenatal care access and early prenatal care utilization. The 2014 Medicaid expansion under the Patient Protection and Affordable Care Act allowed states to expand Medicaid coverage to nonelderly adults with incomes up to 138% of the federal poverty level. Its implementation has led to a significant increase in prenatal care access and utilization. OBJECTIVE: This study aimed to assess the association of Medicaid expansion under the Affordable Care Act with eclampsia incidence. STUDY DESIGN: This natural experiment study was based on US birth certificate data from January 2010 to December 2018 in 16 states that expanded Medicaid in January 2014 and in 13 states that did not expand Medicaid during the study period. The outcome was eclampsia incidence, the intervention was the implementation of the Medicaid expansion, and the exposure was state expansion status. Using the interrupted time series method, we compared temporal trends in the incidence of eclampsia before and after the intervention in expansion vs non-expansion states with adjustments for patient and hospital county characteristics. RESULTS: Of the 21,570,021 birth certificates analyzed, 11,433,862 (53.0%) were in expansion states and 12,035,159 (55.8%) were in the postintervention period. The diagnosis of eclampsia was recorded in 42,677 birth certificates or 19.8 per 10,000 (95% confidence interval, 19.6-20.0). The incidence of eclampsia was higher for Black people (29.1 per 10,000) than for White (20.7 per 10,000), Hispanic (15.3 per 10,000), and birthing people of other race and ethnicity (15.4 per 10,000). In the expansion states, the incidence of eclampsia increased during the preintervention period and decreased during the postintervention period; in the nonexpansion states, a reverse pattern was observed. A statistically significant difference was observed between expansion and nonexpansion states in temporal trends between the pre- and postintervention periods, with an overall 1.6% decrease (95% confidence interval, 1.3-1.9) in the incidence of eclampsia in expansion states compared with nonexpansion states. The results were consistent in subgroup analyses according to maternal race and ethnicity, education level (less than high school or high school and higher), parity (nulliparous or parous), delivery mode (vaginal or cesarean delivery), and poverty in the residence county (high or low). CONCLUSION: Implementation of the Affordable Care Act Medicaid expansion was associated with a small statistically significant reduction in the incidence of eclampsia. Its clinical significance and cost-effectiveness remain to be determined.
