Abstract Objective This study aimed to analyze whether hospital safety-net burden status is associated with increased risk for severe maternal morbidity (SMM) and postpartum readmissions. Study Design The 2010 to 2014 Nationwide Readmissions Database was utilized for this retrospective cohort study. Hospitals were categorized as high-burden hospitals (25% of hospitals with the highest safety-net burden), medium-burden hospitals (50% of hospitals with intermediate safety-net burden), and low-burden hospitals (25% of hospitals with the lowest safety-net burden) based on the proportions of Medicaid or uninsured patients. Risk for (1) SMM, (2) 60-day postpartum readmissions, and (3) SMM during postpartum readmissions was analyzed. Unadjusted and adjusted log-linear regression models were performed, respectively, for these outcomes with unadjusted risk ratio (RR) and adjusted RR (aRR) as measures of effect. Adjusted models included demographic, hospital, and clinical factors. Results High-burden safety-net status was associated with increased risk for SMM compared with low-burden safety-net status in both unadjusted (RR: 1.51, 95% confidence interval [CI]: 1.50–1.53) and adjusted analyses (aRR: 1.27, 95% CI: 1.25–1.30). High-burden status was also associated with increased risk for readmissions in unadjusted analyses (RR: 1.42, 95% CI: 1.40–1.44), although this risk was attenuated in adjusted analyses (aRR: 1.07, 95% CI: 1.06–1.08). High-burden status was associated with significantly increased risk for readmission for uterine infections, hypertensive diseases of pregnancy, and psychiatric diagnoses. High-burden status was not associated with severe morbidity during readmissions in adjusted or unadjusted analyses (RR: 1.02, 95% CI: 0.98–1.05; aRR: 0.95, 95% CI: 0.92–0.99). Conclusion This study found that high safety-net burden hospitals may be a higher risk setting for obstetric care. Improvement of outcomes in high-burden settings may be important in overall efforts to reduce maternal risk.

Abstract Objective This study aimed to examine whether prenatal biochemical screening analytes are associated with an increased risk of severe maternal morbidity (SMM) or maternal mortality. Study Design This population-based cohort study includes all women in Ontario, Canada, who underwent prenatal screening from 2001 to 2011. Increasing fifth percentiles of the multiple of the median (MoM) for alphafetoprotein (AFP), total human chorionic gonadotropin, unconjugated estriol (uE3), dimeric inhibin-A (DIA), and pregnancy-associated plasma protein A were evaluated. An abnormally high concentration (>95th percentile MoM) for each analyte, individually and combined, was also evaluated. The main outcome assessed was the adjusted relative risk (aRR) of SMM or maternal mortality from 20 weeks' gestation up to 26 weeks thereafter. Results Among 748,972 pregnancies, 11,177 resulted in SMM or maternal mortality (1.5%). Except for uE3, the aRR of SMM or maternal mortality increased in association with increasing fifth percentiles of the MoM for all analytes. AFP (aRR: 2.10; 95% confidence interval [CI]: 1.97–2.25) and DIA (aRR: 2.33; 95% CI: 1.98–2.74) > 95th versus ≤ 5th percentile of the MoM were especially associated with SMM or death. Conclusion Women with abnormally high concentrations of certain prenatal biochemical analytes may be at a higher risk of SMM or death in pregnancy or postpartum.

CONTEXT AND OBJECTIVE: Evaluation of severe maternal morbidity has been used in monitoring of maternal health. The objective of this study was to estimate its incidence and main causes in São Luís, Maranhão, Brazil. DESIGN AND SETTING: Prospective longitudinal study, carried out in two public high-risk maternity hospitals and two public intensive care units (ICUs) for referral of obstetric cases from the municipality. METHODS: Between March 1, 2009, and February 28, 2010, all cases of severe maternal morbidity according to the Mantel and Waterstone criteria were identified. The sociodemographic and healthcare characteristics of the extremely severe cases were compared with the less severe cases, using the Fisher, Χ2, Student t and Mann-Whitney tests, with a significance level of < 0.05. RESULTS: 127 cases of severe maternal morbidity were identified among 8,493 deliveries, i.e. an incidence of 15.0/1000 deliveries. Out of 122 cases interviewed, 121 cases were within the Waterstone criteria and 29 were within the Mantel criteria, corresponding to incidences of 14.1/1000 and 3.4/1000 deliveries, respectively. These rates were lower than those described in the literature, possibly due to case loss. The main causes were hypertension during pregnancy, which was more frequent in less severe cases (P = 0.001) and obstetric hemorrhage, which was more common among extremely severe cases (P = 0.01). CONCLUSIONS: Direct obstetric disorders were the main causes of severe maternal morbidity in São Luís, Maranhão. Investigation and monitoring of severe morbidity may contribute towards improving obstetric care in the municipality.

Abstract Interpregnancy interval (IPI) associates with adverse perinatal outcomes, but its contribution to severe maternal morbidity (SMM) remains unclear. We examined the association between IPI and SMM, using data linked across sequential pregnancies to women in California 1997-2012. Adjusting for confounders measured at the index pregnancy (i.e. the first in a pair of consecutive pregnancies), we estimated adjusted risk ratios (aRRs) of SMM related to the subsequent pregnancy. We further conducted within-mother comparisons and analyses stratified by parity and maternal age at the index pregnancy. Compared to 18-23 months, IPI&lt;6 months had same risk for SMM in between-mother comparison (aRR=0.96, 95%CI 0.91, 1.02) but lower risk in within-mother comparison (aRR=0.76, 95% confidence interval (CI) 0.67, 0.86). IPI 24-59 months and IPI≥60 months associated with increased risk of SMM in both between-mother (aRR=1.18, 95%CI 1.13, 1.23 and aRR=1.76, 95% CI 1.68, 1.85 respectively) and within-mother comparisons (aRR=1.22, 95%CI 1.11, 1.34 and aRR=1.88, 95% CI 1.66, 2.13 respectively). The association between IPI and SMM did not substantially differ by maternal age and parity. Longer IPI was associated with increased risk of SMM, which may be partly attributed to interpregnancy health.

Abstract Hypertensive disorders of pregnancy (HDP) are a leading cause of severe maternal morbidity (SMM), yet mediation by cesarean delivery is largely unexplored. We investigated the association between HDP and SMM in a cohort of deliveries at a safety-net institution in Atlanta, Georgia, during 2016–2018. Using multivariable generalized linear models, we estimated adjusted risk differences, adjusted risk ratios, and 95% confidence intervals for the association between HDP and SMM. We examined interactions with cesarean delivery and used mediation analysis with 4-way decomposition to estimate excess relative risks. Among 3,723 deliveries, the SMM rate for women with and without HDP was 124.4 per 1,000 and 52.0 per 1,000, respectively. The adjusted risk ratio for the total effect of HDP on SMM was 2.55 (95% confidence interval (CI): 2.15, 3.39). Approximately 55.2% (95% CI: 25.7, 68.5) of excess relative risk was due to neither interaction nor mediation, 24.9% (95% CI: 15.4, 50.0) was due to interaction between HDP and cesarean delivery, 9.6% (95% CI: 3.4, 15.2) was due to mediation, and 10.3% (95% CI: 5.4, 20.3) was due to mediation and interaction. HDP are a potentially modifiable risk factor for SMM; implementing evidence-based interventions for the prevention and treatment of HDP is critical for reducing SMM risk.

Objective Small-for-gestational age infants are at an increased risk for disabilities and chronic health problems. Smoking and hypertension during pregnancy pose significant risks for fetal growth restriction. The study aims to identify whether (1) the timing of tobacco use modifies the risk of small-for-gestational age, (2) there are differences in association by percentile of small-for-gestational age (3rd, 5th, and 10th percentile), and (3) the effect of tobacco exposure on small-for-gestational age outcome is mediated by hypertension. Materials and Methods Data were obtained from the 2009 Natality public use file available through the National Center for Health Statistics. Women were categorized into 11 groups depending on the trimester of tobacco exposure, the number of daily cigarettes smoked, and presence of hypertension. Multivariable log-linear regression models were performed to determine the association between percentile of singleton small-for-gestational age outcome (3rd, 5th, and 10th), trimester and degree of tobacco exposure, and hypertension. Results Hypertension and smoking worked synergistically to restrict fetal growth. Hypertensive women who smoked heavily in all three trimesters were 4.34 times more likely to give birth to a 3rd percentile small-for-gestational age infant compared with nonsmoking normotensive women. Conclusion The timing and duration of tobacco exposure mediates the risk and severity of fetal growth restriction.

Objective This study aimed to characterize risk for postpartum complications based on specific hypertensive diagnosis at delivery. Study Design This retrospective cohort study used the 2010 to 2014 Nationwide Readmissions Database to identify 60-day postpartum readmissions. Delivery hospitalizations were categorized based on hypertensive diagnoses as follows: (1) preeclampsia with severe features, (2) superimposed preeclampsia, (3) chronic hypertension, (4) preeclampsia without severe features, (5) gestational hypertension, or (6) no hypertensive diagnosis. Risks for 60-day readmission was determined based on hypertensive diagnosis at delivery. The following adverse outcomes during readmissions were analyzed: (1) stroke, (2) pulmonary edema and heart failure, (3) eclampsia, and (4) severe maternal morbidity (SMM). We fit multivariable log-linear regression models to assess the magnitude of association between hypertensive diagnoses at delivery and risks for readmission and associated complications with adjusted risk ratios (aRR) as measures of effect. Results From 2010 to 2014, 15.7 million estimated delivery hospitalizations were included in the analysis. Overall risk for 60-day postpartum readmission was the highest among women with superimposed preeclampsia (6.6%), followed by preeclampsia with severe features (5.2%), chronic hypertension (4.0%), preeclampsia without severe features (3.9%), gestational hypertension (2.9%), and women without a hypertensive diagnosis (1.5%). In adjusted analyses for pulmonary edema and heart failure as the outcome, risks were the highest for preeclampsia with severe features (aRR = 7.82, 95% confidence interval [CI]: 6.03, 10.14), superimposed preeclampsia (aRR = 8.21, 95% CI: 5.79, 11.63), and preeclampsia without severe features (aRR = 8.87, 95% CI: 7.06, 11.15). In the adjusted model for stroke, risks were similarly highest for these three hypertensive diagnoses. Evaluating risks for SMM during postpartum readmission, chronic hypertension and superimposed preeclampsia were associated with the highest risks. Conclusion Chronic hypertension was associated with increased risk for a broad range of adverse postpartum outcomes. Risk estimates associated with chronic hypertension with and without superimposed preeclampsia were similar to preeclampsia with severe features for several outcomes. Key Points

BackgroundTotal knee arthroplasty (TKA) is among the most common surgical procedures performed in the USA and comprises an outsized proportion of Medicare expenditures. Previous work-associated higher safety-net burden hospitals with increased morbidity and in-hospital mortality following total hip arthroplasty. Here, we examine the association of safety-net burden on postoperative outcomes after TKA.MethodsWe retrospectively analyzed 1 141 587 patients aged ≥18 years undergoing isolated elective TKA using data from the State Inpatient Databases for Florida, Kentucky, Maryland, New York and Washington from 2007 through 2018. Hospitals were grouped into tertiles by safety-net burden status, defined by the proportion of inpatient cases billed to Medicaid or unpaid (low: 0%–16.83%, medium: 16.84%–30.45%, high: ≥30.45%). Using generalized estimating equation models, we assessed the association of hospital safety-net burden status on in-hospital mortality, patient complications and length of stay (LOS). We also analyzed outcomes by anesthesia type in New York State (NYS), the only state with this data.ResultsMost TKA procedures were performed at medium safety-net burden hospitals (n=6 16 915, 54%), while high-burden hospitals performed the fewest (n=2 04 784, 17.9%). Overall in-patient mortality was low (0.056%), however, patients undergoing TKA at medium-burden hospitals were 40% more likely to die when compared with patients at low-burden hospitals (low: 0.043% vs medium: 0.061%, adjusted OR (aOR): 1.40, 95% CI 1.09 to 1.79, p=0.008). Patients who underwent TKA at medium or high safety-net burden hospitals were more likely to experience intraoperative complications (low: 0.2% vs medium: 0.3%, aOR: 1.94, 95% CI 1.34 to 2.83, p<0.001; low: 0.2% vs high: 0.4%, aOR: 1.91, 95% CI 1.35 to 2.72, p<0.001). There were no statistically significant differences in other postoperative complications or LOS between the different safety-net levels. In NYS, TKA performed at high safety-net burden hospitals was more likely to use general rather than regional anesthesia (low: 26.7% vs high: 59.5%, aOR: 4.04, 95% CI 1.05 to 15.5, p=0.042).ConclusionsPatients undergoing TKA at higher safety-net burden hospitals are associated with higher odds of in-patient mortality than those at low safety-net burden hospitals. The source of this mortality differential is unknown but could be related to the increased risk of intraoperative complications at higher burden centers.

Introduction: Postpartum hypertension can be persistent, following a pregnancy complicated by hypertension, or new onset ( de novo ), following a normotensive pregnancy. The postpartum period is traditionally defined as six weeks after delivery, yet accruing evidence shows that hypertension underlies the majority of severe maternal morbidity events through a year postpartum. While guidelines for enhanced monitoring of women at risk of persistent postpartum hypertension exist, less is known about risk factors for de novo postpartum hypertension. The aim of this study is to estimate the incidence of and identify risk factors for de novo postpartum hypertension among a diverse safety-net hospital population through the entire year postpartum. Hypothesis: We assessed the hypothesis that women with de novo postpartum hypertension share similar demographic and reproductive characteristics to women at increased risk of cardiovascular related maternal morbidity. Methods: We conducted a cohort study of 8,531 deliveries at Boston Medical Center from 2016-2018. Data on demographics, reproductive history, and labor and delivery were obtained from medical records. All documented blood pressure measures from pregnancy through 12 months postpartum were extracted. Women with chronic hypertension or hypertensive disorders of pregnancy were excluded. De novo postpartum hypertension was defined as two separate blood pressure readings with systolic blood pressure (SBP) ≥ 140 mmHg and/or diastolic blood pressure (DBP) ≥90 mmHg at least 48 hours after delivery. Severe de novo hypertension was defined using criteria of SBP ≥160 and/or DPB ≥110. We examined the distribution of demographic and pregnancy characteristics among women with and without de novo postpartum hypertension. Secondary analyses restricting to women with healthcare visits after six weeks postpartum were also conducted. Results: Among the 6,631 women without a history of hypertension, 10% (n=660) developed de novo postpartum hypertension; a third of whom had severe hypertension (n=225). Compared to women without de novo hypertension; cases were more likely to be non-Hispanic Black; delivered via cesearean section; have had a preterm delivery; and be multiparous. In analyses restricted to women with visits extending past six weeks postpartum (n=3,272), the incidence of de novo postpartum hypertension was 16.6%. Approximately 30% of these cases were diagnosed after the traditionally used six week period. Conclusion: In conclusion, 1 in 10 women with normotensive pregnancies experience de novo hypertension in the year after delivery, with a third of these cases developing after six weeks. Opportunities to monitor and manage women at the highest risk of de novo hypertension throughout the entire year postpartum could mitigate cardiovascular related maternal morbidity.
