RESUMO
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.
RESUMO
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.

Importance: Individuals with congenital heart disease (CHD) are increasingly reaching childbearing age, are more prone to adverse pregnancy events, and uncommonly undergo recommended cardiac evaluations. Data to better understand resource allocation and financial planning are lacking. Objective: To examine health care use and costs for patients with CHD during pregnancy. Design, Setting, and Participants: This retrospective cohort study was performed from January 1, 2010, to December 31, 2016, using Merative MarketScan commercial insurance data. Participants included patients with CHD and those without CHD matched 1:1 by age, sex, and insurance enrollment year. Pregnancy claims were identified for all participants. Data were analyzed from September 2022 to March 2024. Exposures: Baseline characteristics (age, US region, delivery year, insurance type) and pregnancy-related events (obstetric, cardiac, and noncardiac conditions; birth outcomes; and cesarean delivery). Main Outcomes and Measures: Health service use (outpatient physician, nonphysician, emergency department, prescription drugs, and admissions) and costs (total and out-of-pocket costs adjusted for inflation to represent 2024 US dollars). Results: A total of 11â¯703 pregnancies (mean [SD] maternal age, 31.5 [5.4] years) were studied, with 2267 pregnancies in 1785 patients with CHD (492 pregnancies in patients with severe CHD and 1775 in patients with nonsevere CHD) and 9436 pregnancies in 7720 patients without CHD. Compared with patients without CHD, pregnancies in patients with CHD were associated with significantly higher health care use (standardized mean difference [SMD] range, 0.16-1.46) and cost (SMD range, 0.14-0.55) except for out-of-pocket inpatient and ED costs. After adjustment for covariates, having CHD was independently associated with higher total (adjusted cost ratio, 1.70; 95% CI, 1.57-1.84) and out-of-pocket (adjusted cost ratio, 1.40; 95% CI, 1.22-1.58) costs. The adjusted mean total costs per pregnancy were $15â¯971 (95% CI, $15â¯480-$16â¯461) for patients without CHD, $24â¯290 (95% CI, $22â¯773-$25â¯806) for patients with any CHD, $26â¯308 (95% CI, $22â¯788-$29â¯828) for patients with severe CHD, and $23â¯750 (95% CI, $22â¯110-$25â¯390) for patients with nonsevere CHD. Patients with vs without CHD incurred $8319 and $700 higher total and out-of-pocket costs per pregnancy, respectively. Conclusions and Relevance: This study provides novel, clinically relevant estimates for the cardio-obstetric team, patients with CHD, payers, and policymakers regarding health care and financial planning. These estimates can be used to carefully plan for and advocate for the comprehensive resources needed to care for patients with CHD.

Objective: To assess the impact of an evidence-informed protocol for management of placenta accreta spectrum (PAS). Methods: This was a retrospective cohort study of patients who underwent cesarean hysterectomy (c-hyst) for suspected PAS from 2012 to 2022 at a single tertiary care center. Perioperative outcomes were compared pre- and post-implementation of a standardized Multidisciplinary Approach to the Placenta Service (MAPS) protocol, which incorporates evidence-informed perioperative interventions including preoperative imaging and group case review. Intraoperatively, the MAPS protocol includes placement of ureteral stents, possible placental mapping with ultrasound, and uterine artery embolization by interventional radiology. Patients suspected to have PAS on prenatal imaging who underwent c-hyst were included in the analysis. Primary outcomes were intraoperative complications and postoperative complications. Secondary outcomes were blood loss, need for ICU, and length of stay. Proportions were compared using Fisher's exact test, and continuous variables were compared used t-tests and Mood's Median test. Results: There were no differences in baseline demographics between the pre- (n = 38) and post-MAPS (n = 34) groups. The pre-MAPS group had more placenta previa (95% pre- vs. 74% post-MAPS, p = 0.013) and prior cesarean sections (2 prior pre- vs. 1 prior post-MAPS, p = 0.012). The post-MAPS group had more severe pathology (PAS Grade 3 8% pre- vs. 47% post-MAPS, p = 0.001). There were fewer intraoperative complications (39% pre- vs.3% post-MAPS, p < 0.001), postoperative complications (32% pre- vs.12% post-MAPS, p = 0.043), hemorrhages >1l (95% pre- vs.65% post-MAPS, p = 0.001), ICU admissions (59% pre- vs.35% post-MAPS, p = 0.04) and shorter hospital stays (10 days pre- vs.7 days post-MAPS, p = 0.02) in the post-MAPS compared to pre-MAPS patients. Neonatal length of stay was 8 days longer in the post-MAPS group (9 days pre- vs. 17 days post-MAPS, p = 0.03). Subgroup analyses demonstrated that ureteral stent placement and uterine artery embolization (UAE) may be important steps to reduce complications and ICU admissions. When comparing just those who underwent UAE, patients in the post-MAPS group experienced fewer hemorrhages greater five liters (EBL >5l 43% pre- vs.4% post-MAPS, p = 0.007). Conclusion: An evidence-informed approach to management of PAS was associated with decreased complication rate, EBL >1l, ICU admission and length of hospitalization, particularly for patients with severe pathology.
RESUMO
OBJECTIVE: This study aimed to identify predictors of immediate postpartum breastfeeding among women with maternal cardiac disease (MCD). STUDY DESIGN: This study included all gravidas with MCD who delivered at a single institution from 2012 to 2018. Charts were abstracted for maternal demographics, obstetrical outcome, cardiac diagnoses, cardiac risk stratification scores, and prepregnancy echocardiogram findings. Kruskal-Wallis and Fisher's exact tests were used to compare the breastfeeding (BF) group versus the nonbreastfeeding (NBF) group. Logistic regression was used to obtain odds ratios (ORs) with 95% confidence intervals (CIs). RESULTS: Among 211 gravidas with MCD, 12% were not breastfeeding at the time of postpartum hospital discharge. Compared with the BF group, the NBF group had a significantly higher proportion of women with cardiomyopathy (21% NBF vs. 7% BF, OR 3.44, 95% CI 1.12-10.71), with modified World Health Organization (WHO) classification ≥III (33 vs. 14%, OR 3.16, 95% CI 1.22-8.15), and with prepregnancy ejection fraction (EF) < 50% (55 vs. 14%, OR 7.20, 95% CI 1.92-27.06). There were otherwise no differences between the two groups with regards to other cardiac diagnoses or cardiac risk scores. CONCLUSION: In women with MCD, cardiomyopathy, modified WHO class ≥III, and a prepregnancy EF < 50% were associated with NBF in the immediate postpartum period. These findings may guide providers in identifying a subset of women with MCD who can benefit from increased breastfeeding counseling and support. KEY POINTS: · Eighty-two percent of patients with cardiac disease are breastfeeding at the time of postpartum discharge.. · Cardiomyopathy is associated with an increased odds of not breastfeeding at postpartum discharge.. · Rationale for not breastfeeding is infrequently documented in the medical record..
RESUMO
BACKGROUND: Continuous glucose monitors provide detailed information regarding glycemic control in pregnant patients with type 1 diabetes. Little data have been published examining the association between continuous glucose monitor parameters and perinatal outcomes among gravidas with type 1 diabetes using continuous glucose monitors. OBJECTIVE: This study aimed to examine the association between perinatal outcomes and time-in-range as assessed by continuous glucose monitors used in pregnant individuals with type 1 diabetes. We hypothesized that higher time-in-range would be associated with lower risk of adverse perinatal outcomes. STUDY DESIGN: This multicenter retrospective cohort study included all gravidas with type 1 diabetes using continuous glucose monitors who delivered from 2020 to 2022 at 5 University of California sites. Only those with continuous glucose monitor target range set to 70 to 140 mg/dL (±10 mg/dL) were included. Time-in-range (%) was recorded at 12, 16, 20, 24, 28, and 32 weeks. The primary maternal and neonatal outcomes were preeclampsia and large for gestational age, defined as birthweight ≥95th percentile. Kruskal-Wallis tests were used to compare median time-in-range between those with and without the primary outcomes. Log-binomial regression was used to obtain risk ratios, with adjustment for microvascular disease and years with type 1 diabetes. RESULTS: A total of 91 patients were included. Most used an insulin pump (81%) and did not have diabetic microvascular disease (72%). Median time since diagnosis of type 1 diabetes was 16 years, and median periconception hemoglobin A1c was 6.7%. Compared with those with preeclampsia, normotensive gravidas had significantly higher time-in-range at nearly every time point. A similar pattern was observed for those with normal-birthweight infants compared with large-for-gestational-age infants. On adjusted analyses, every 5-unit increase in time-in-range at 12 weeks was associated with 45% and 46% reductions in the risks of preeclampsia and large for gestational age, respectively (preeclampsia: adjusted risk ratio, 0.55; 95% confidence interval, 0.30-0.99; large for gestational age: adjusted risk ratio, 0.54; 95% confidence interval, 0.29-0.99). CONCLUSION: Higher time-in-range is associated with lower risk of preeclampsia and large for gestational age. This association is observed early in gestation, when each 5-unit increase in time-in-range is associated with â¼50% reduction in the risk of these complications. These findings can be used to counsel patients regarding the risk of pregnancy complications at specific time-in-range values, and to encourage patients that even small improvements in time-in-range can have significant impact on pregnancy outcomes. Larger studies are needed to further explore these findings and to identify optimal time-in-range to reduce perinatal complication rates.
RESUMO
There are unique challenges that arise from participating in remote clinical trials. Broadly, findings suggest that participants enrolled in digital intervention trials are more likely to disengage or prematurely dropout than participants in face-to-face trials. Thus, optimizing contact with participants via video-conferencing platforms to build rapport and encourage commitment to the study is critical. Still, challenges with video-conferencing visits can pose challenges. Some of these challenges include a lack of clarity about study requirements, difficulties demonstrating staff engagement and building rapport, and the technical challenges of using video-conferencing software. These challenges can affect participant retention, study validity, and the willingness of underserved groups to participate in research. In the context of a remote randomized clinical trial evaluating a digital intervention for prenatal insomnia, we discuss strategies used to counteract these challenges, including the use of virtual orientation sessions, and practical recommendations to improve staff engagement with participants. These findings are relevant to research teams conducting remote clinical trials, especially those seeking to recruit and retain participants from populations currently and historically underrepresented in research.

OBJECTIVES: Patients with congenital heart disease (CHD) are increasingly pursuing pregnancy, highlighting the need for data on late cardiovascular events (more than 6 months after delivery). We aimed to determine the incidence of late cardiovascular events in postpartum patients with CHD and evaluate the accuracy of the existing risk scores in predicting these events. STUDY DESIGN: We identified patients with CHD who delivered between 2008 and 2020 at a tertiary centre and had follow-up data for greater than 6 months post partum. Late cardiovascular events were defined as heart failure, arrhythmia, thromboembolic events, endocarditis, urgent cardiovascular interventions or death. Survival analysis and Cox proportional model were used to estimate the incidence of late cardiovascular events and determine the hazard ratio of factors associated with these events. RESULTS: Of 117 patients, 19% had 36 late cardiovascular events over a median follow-up of 3.8 years. Annual incidence of any late cardiovascular event was 5.7%. Hazards of late cardiovascular events were significantly higher among those with higher Cardiac Disease in Pregnancy Study (CARPREG) II and Zwangerschap bij Aangeboren HARtAfwijking-Pregnancy in Women With Congenital Heart Disease (ZAHARA) risk scores and among patients with prepregnancy New York Heart Association class≥II. C-statistic to predict the late cardiovascular events was highest for ZAHARA (0.7823), followed by CARPREG II (0.6902) and prepregnancy New York Heart Association class≥ II (0.6677). CONCLUSIONS: Currently available risk tools designed for prognostication during the peripartum period can also be used to determine risks of late maternal cardiovascular events among those with CHD. These findings provide important new information for counselling and risk modification.

OBJECTIVE: To evaluate the performance of two previously published calculators in predicting cesarean delivery after induction of labor in an external population. METHODS: This was a cohort study including all nulliparous pregnant patients with singleton, term, vertex fetuses; intact membranes; and unfavorable cervices who underwent induction of labor between 2015 and 2017 at an academic tertiary care institution. Individual predicted cesarean risk scores were calculated with two previously published calculators. For each calculator, patients were stratified into three risk groups (lower, middle, and upper thirds) of approximately equivalent size. Predicted and observed incidences of cesarean delivery were compared with two-tailed binomial tests of probability in the overall population and in each risk group. RESULTS: A total of 846 patients met inclusion criteria, and 262 (31.0%) had cesarean deliveries, which was significantly lower than overall predicted rates of 40.0% and 36.2% with the two calculators (both P <.01). Both calculators significantly overestimated risk of cesarean delivery in higher risk tertiles (all P <.05). The areas under the receiver operating characteristic for both calculators were 0.57 or less in the overall population and in each risk group, suggesting poor predictive value. Higher predicted risk tertile in both calculators was not associated with any maternal or neonatal outcomes except wound infection. CONCLUSION: Both previously published calculators had poor performance in this population, with neither calculator accurately predicting the incidence of cesarean delivery. Patients and health care professionals might be discouraged regarding trial of labor induction by falsely high predicted risk-of-cesarean scores. We caution against widespread implementation of these calculators without further population-specific refinement and adjustment.

OBJECTIVE: Unplanned pregnancies in women with maternal cardiac disease (MCD) are associated with increased morbidity and mortality, but the majority of these individuals do not use highly reliable contraception on postpartum hospital discharge. Contraceptive counseling in this population outside of pregnancy is incomplete and counseling during pregnancy remains poorly characterized. Our objective was to evaluate the provision and quality of contraceptive counseling for individuals with MCD during pregnancy. METHODS: All individuals with MCD who delivered between 2008 and 2021 at a tertiary care institution with a multidisciplinary cardio-obstetrics team were sent a 27-question survey. A subset of questions were derived from the validated Interpersonal Quality in Family Planning (IQFP) survey, which emphasizes interpersonal connection, adequate information, and decision support for the individual. Each participant received a $15 gift card for survey completion. We performed chart review for clinical and demographic details, including cardiac risk score. RESULTS: Of 522 individuals to whom the survey was sent, 133 responded and met inclusion criteria. Overall, 67% discussed contraception with their general obstetrician, 36% with their maternal-fetal medicine (MFM) specialist, and 24% with their cardiologist. Compared to individuals with low cardiac risk scores, those with high cardiac risk scores had a nonsignificant trend toward being more likely to discuss contraception with a MFM provider (52% vs 33%, p = .08). 65% reported that their provider was 'excellent' or 'good' in all IQFP domains. Respondents valued providers who respected their autonomy and offered thorough counseling. Respondents disliked feeling pressured or uninformed about the safety of contraceptive options. CONCLUSION: Most individuals with MCD reported excellent contraceptive counseling during pregnancy. Additional work is needed to understand barriers to and enablers for effective, patient-centered contraceptive counseling and use in this population.

OBJECTIVE: Severe preeclampsia diagnosed at or prior to 34 weeks is an indication for preterm delivery. Many patients with severe preeclampsia develop fetal growth restriction as a result of the placental dysfunction associated with both conditions. The ideal mode of delivery in cases of preterm severe preeclampsia with fetal growth restriction remains controversial, with providers often proceeding directly to cesarean delivery rather than attempting a trial of labor due to theoretic concerns about the harms of labor in the face of placental dysfunction. There are limited data supporting this approach. This study evaluates whether the presence of fetal growth restriction affects the ultimate mode of delivery or neonatal outcomes among pregnancies with severe preeclampsia undergoing induction of labor at or before 34 weeks. METHODS: This was a retrospective cohort study of singletons with severe preeclampsia undergoing induction of labor ≤ 34 weeks at a single center between January 2015 and April 2022. The primary predictor was fetal growth restriction, defined as estimated fetal weight < 10th percentile for gestational age on ultrasound. Mode of delivery and neonatal outcomes were compared between those with and without fetal growth restriction using Fisher's exact and Kruskal-Wallis tests, and multivariate logistic regression was used to obtain adjusted odds ratios. RESULTS: 159 patients were included (N = 117 without fetal growth restriction, N = 42 with fetal growth restriction). There was no difference in vaginal delivery between the groups (70% vs 67%, p = .70). While those with fetal growth restriction had a higher incidence of respiratory distress syndrome and longer neonatal hospital stay, these differences were not statistically significant after adjusting for gestational age at delivery. There were no significant differences in other neonatal outcomes, including Apgar score, cord blood gases, intraventricular hemorrhage, necrotizing enterocolitis, neonatal sepsis, and neonatal demise. CONCLUSION: For pregnancies complicated by severe preeclampsia that require delivery ≤ 34 weeks, the likelihood of successful vaginal delivery following induction of labor does not differ based on presence of fetal growth restriction. Furthermore, fetal growth restriction is not an independent risk factor for adverse neonatal outcomes in this population. Induction of labor should be considered a reasonable approach and should be routinely offered to patients with concurrent preterm severe preeclampsia and fetal growth restriction.

BACKGROUND: With improved therapies, an increasing number of patients with Fontan circulation reach reproductive age. Pregnant patients with Fontan circulation are at high risk of obstetrical complications. Most data for pregnancies complicated by Fontan circulation and associated complications stem from single-center studies, with limited national epidemiologic data available. OBJECTIVE: This study aimed to evaluate temporal trends in deliveries to pregnant individuals with Fontan palliation using nationwide data and to estimate associated obstetrical complications among these deliveries. STUDY DESIGN: Delivery hospitalizations were abstracted from the 2000 to 2018 Nationwide Inpatient Sample. Deliveries complicated by Fontan circulation were identified using diagnosis codes, and trends in the rates of these deliveries were assessed using joinpoint regression. Baseline demographics and obstetrical outcomes (including severe maternal morbidity, a composite of serious obstetrical and cardiac complications) were assessed. Univariable log-linear regression models were fit comparing risks of outcomes among deliveries of patients with and without Fontan circulation. RESULTS: A total of 509 pregnancies complicated by Fontan circulation were identified at a rate of 7 per 1 million delivery hospitalizations, with a temporal increase from 2.4 to 30.3 cases per 1 million from 2000 to 2018 (P<.01). Deliveries complicated by Fontan circulation were at higher risk of hypertensive disorders (relative risk, 1.79; 95% confidence interval, 1.42-2.27), preterm delivery (relative risk, 2.37; 95% confidence interval, 1.90-2.96), postpartum hemorrhage (relative risk, 4.28; 95% confidence interval, 3.35-5.45), and severe maternal morbidity (relative risk, 6.09; 95% confidence interval, 4.54-8.17) than deliveries not complicated by Fontan circulation. CONCLUSION: The rates of deliveries of patients with Fontan palliation are increasing on a national level. These deliveries have higher risks of obstetrical complications and severe maternal morbidity. Additional national clinical data are necessary to better understand the complications in pregnancies complicated by Fontan circulation, to improve patient counseling, and to reduce maternal morbidity.

OBJECTIVE: To analyze temporal trends in and risk factors for postpartum hemorrhage and to analyze the association of risk factors with postpartum hemorrhage-related interventions such as blood transfusion and peripartum hysterectomy. METHODS: This repeated cross-sectional study analyzed delivery hospitalizations from 2000 to 2019 in the National (Nationwide) Inpatient Sample. Trends analyses were conducted using joinpoint regression to estimate the average annual percent change (AAPC) with 95% CIs. Unadjusted and adjusted survey-weighted logistic regression models were performed to evaluate the relationship between postpartum hemorrhage risk factors and likelihood of 1) postpartum hemorrhage, 2) postpartum hemorrhage that requires blood transfusion, and 3) peripartum hysterectomy in the setting of postpartum hemorrhage, with unadjusted odds ratios and adjusted odds ratios with 95% CIs as measures of association. RESULTS: Of an estimated 76.7 million delivery hospitalizations, 2.3 million (3.0%) were complicated by postpartum hemorrhage. From 2000 to 2019, the rate of postpartum hemorrhage increased from 2.7% to 4.3% (AAPC 2.6%, 94% CI 1.7-3.5%). Over the study period, the proportion of deliveries to individuals with at least one postpartum hemorrhage risk factor increased from 18.6% to 26.9% (AAPC 1.9%, 95% CI 1.7-2.0%). Among deliveries complicated by postpartum hemorrhage, blood transfusions increased from 5.4% to 16.7% from 2000 to 2011 and then decreased from 16.7% to 12.6% from 2011 to 2019. Peripartum hysterectomy among hospitalized individuals with postpartum hemorrhage increased from 1.4% to 2.4% from 2000 to 2009, did not change significantly from 2009 to 2016, and then decreased significantly from 2.1% to 0.9% from 2016 to 2019 (AAPC -27.0%, 95% CI -35.2% to -17.6%). Risk factors associated with postpartum hemorrhage and transfusion and hysterectomy in the setting of postpartum hemorrhage included prior cesarean delivery with previa or placenta accreta, placenta previa without prior cesarean delivery, and antepartum hemorrhage or placental abruption. CONCLUSION: Postpartum hemorrhage and related risk factors increased over a 20-year period. Despite the increased postpartum hemorrhage rates, blood transfusions, and hysterectomy rates decreased in recent years.

Women who are pregnant and living with HIV have traditionally been excluded from clinical trials regarding new pharmacotherapy. Immediate initiation of antiretroviral therapy (ART) is recommended for women who are pregnant and living with HIV. Integrase inhibitors (INSTIs) are first-line recommended agents as they lead to more rapid HIV viral load reduction. We conducted a retrospective study of women who are pregnant and living with HIV who received prenatal care at the University of Washington. Mothers were categorized by ART class: INSTI, protease inhibitors (PI), and non-nucleoside reverse transcriptase inhibitors (NNRTI). Chi-square and t-tests were used for the analysis of baseline characteristics, and generalized estimating equations were used to adjust for HIV viral suppression between groups. There were a total of 234 mother-infant pairs whose pregnancies progressed beyond 20 weeks. The study demonstrated that women on INSTI regimens were more likely to have a shorter time to viral load suppression than women on NNRTI regimens. Additionally, seven congenital anomalies were identified in this cohort, none of which were neural tube defects. There was no perinatal transmission of HIV to any of the infants. This small cohort of women provides high-quality data regarding the safety and efficacy of INSTI use for both mothers and infants in resource-rich settings.
RESUMO
BACKGROUND: Acute postpartum care utilization and readmissions are increasing in the United States and contribute significantly to maternal morbidity, mortality, and healthcare costs. Currently, there are limited data on the prediction of patients who will require acute postpartum care utilization. OBJECTIVE: To develop and validate a risk prediction model for acute postpartum care utilization. STUDY DESIGN: A retrospective cohort study of delivery hospitalizations with a linked birth certificate and discharge records in California from 2011 to 2015 was divided into a training and testing set for analysis and validation. Predictive models for acute postpartum care utilization using demographic, comorbidity, obstetrical complication, and other factors were developed using a backward stepwise logistic regression on training data. A risk score for acute postpartum care utilization was developed using beta coefficients from the factors remaining in the final multivariable model. Risk scores were validated using the testing dataset. RESULTS: The final sample included 2,045,988 delivery hospitalizations with an acute postpartum care utilization rate of 7.6% in both training and testing cohorts. Twenty-two risk factors were identified for the final multivariable model, including several that were associated with two or more increased odds of acute care utilization (public insurance, postpartum hemorrhage, extremes of maternal age). The mean risk score was 2.45, conferring a 15 times higher risk of acute postpartum care utilization compared to those with a risk score <1 (RR 15.4, 95% CI: 11.0, 21.7). Demographics and test performance characteristics were comparably similar in predictive capability in both models (0.67 in both the training and testing cohorts). CONCLUSION: Risk factors that are identifiable before discharge can be used to create a cumulative risk score to stratify patients at the lowest and highest risk of acute postpartum care utilization with satisfactory accuracy. External validation and the addition of other granular clinical variables are necessary to validate the feasibility of use.

OBJECTIVE: To characterize current trends and outcomes in pregnancies complicated by cystic fibrosis (CF) that resulted in delivery. METHODS: This repeated cross-sectional study used the U.S. National Inpatient Sample to identify delivery hospitalizations of patients with CF between 2000 and 2019. Trends in delivery hospitalizations of patients with CF were assessed using joinpoint regression to determine the average annual percent change (AAPC). The risk of adverse maternal and obstetric outcomes was compared between patients with and without CF using adjusted logistic regression models accounting for demographic, clinical, and hospital characteristics, with adjusted odds ratios (aORs) with 95% CIs as measures of association. The proportion of patients with CF and other chronic conditions such as pregestational diabetes was analyzed over time. RESULTS: From 2000 to 2019, the prevalence of CF at delivery increased from 2.1 to 10.4 per 100,000 deliveries (AAPC 6.7%, 95% CI 5.7-8.2%). The proportion of patients with CF and other chronic conditions increased from 18.0% to 37.3% (AAPC 3.1%, 95% CI 1.0-5.3%). Patients with CF were more likely to experience severe maternal morbidity (aOR 2.61, 95% CI 1.71-3.97), respiratory complications (aOR 17.45, 95% CI 11.85-25.68), venous thromboembolism (aOR 3.59, 95% CI 1.33-9.69), preterm delivery (aOR 2.15, 95% CI 1.79-2.59), abruption and antepartum hemorrhage (aOR 1.63, 95% CI 1.10-2.41), and gestational diabetes (aOR 2.47, 95% CI 2.47-3.70). CONCLUSION: Although still infrequent (approximately 1 in 10,000), deliveries complicated by CF increased approximately fivefold over the study period. The proportion of patients with CF and other chronic conditions is increasing. Patients with CF are at increased risk for a broad range of adverse outcomes.
