Disparities in Chronic Conditions Among Women Hospitalized for Delivery in the United States, 2005-2014

Elevated Blood Pressure in Pregnancy and Long-Term Cardiometabolic Health Outcomes

OBJECTIVE

To examine the association between elevated blood pressure (BP) in the early third trimester and cardiometabolic health 10-14 years after delivery.

METHODS

This is a secondary analysis from the prospective HAPO FUS (Hyperglycemia and Adverse Pregnancy Outcome Follow-Up Study). Blood pressure in the early third trimester was categorized per American College of Cardiology/American Heart Association thresholds for: normal BP below 120/80 mm Hg (reference), elevated BP 120-129/below 80 mm Hg, stage 1 hypertension 130-139/80-89 mm Hg, and stage 2 hypertension 140/90 mm Hg or higher. Cardiometabolic outcomes assessed 10-14 years after the index pregnancy were type 2 diabetes mellitus and measures of dyslipidemia, including low-density lipoprotein (LDL) cholesterol 130 mg/dL or higher, total cholesterol 200 mg/dL or higher, high-density lipoprotein (HDL) cholesterol 40 mg/dL or lower, and triglycerides 200 mg/dL or higher. Adjusted analysis was performed with the following covariates: study field center, follow-up duration, age, body mass index (BMI), height, family history of hypertension and diabetes, smoking and alcohol use, parity, and oral glucose tolerance test glucose z score.

RESULTS

Among 4,692 pregnant individuals at a median gestational age of 27.9 weeks (interquartile range 26.6-28.9 weeks), 8.5% (n=399) had elevated BP, 14.9% (n=701) had stage 1 hypertension, and 6.4% (n=302) had stage 2 hypertension. At a median follow-up of 11.6 years, among individuals with elevated BP, there was a higher frequency of diabetes (elevated BP: adjusted relative risk [aRR] 1.88, 95% CI, 1.06-3.35; stage 1 hypertension: aRR 2.58, 95% CI, 1.62-4.10; stage 2 hypertension: aRR 2.83, 95% CI, 1.65-4.95) compared with those with normal BP. Among individuals with elevated BP, there was a higher frequency of elevated LDL cholesterol (elevated BP: aRR 1.27, 95% CI, 1.03-1.57; stage 1 hypertension: aRR 1.22, 95% CI, 1.02-1.45, and stage 2 hypertension: aRR 1.38, 95% CI, 1.10-1.74), elevated total cholesterol (elevated BP: aRR 1.27, 95% CI, 1.07-1.52; stage 1 hypertension: aRR 1.16, 95% CI, 1.00-1.35; stage 2 hypertension: aRR 1.41 95% CI, 1.16-1.71), and elevated triglycerides (elevated BP: aRR 2.24, 95% CI, 1.42-3.53; stage 1 hypertension: aRR 2.15, 95% CI, 1.46-3.17; stage 2 hypertension: aRR 3.24, 95% CI, 2.05-5.11) but not of low HDL cholesterol.

CONCLUSION

The frequency of adverse cardiometabolic outcomes at 10-14 years after delivery was progressively higher among pregnant individuals with BP greater than 120/80 in the early third trimester.

Perinatal substance use treatment and criminal legal system referral trends

INTRODUCTION

To guide improvements in treatment for pregnant persons with substance use disorders within the criminal legal system, treatment programs must first determine the primary substances of concern for this population. The objective of this study is to compare trends in specific substance use upon admission to treatment in pregnancy, based upon whether referrals originated from the criminal legal system or from another referral source.

METHODS

This research accessed data on perinatal substance use (1995-2021) and referral sources from the Treatment Episode Data Set-Admissions (TEDS-A). Analyses use multiple logistic regressions to evaluate trends in primary substance use leading to treatment admission during pregnancy.

RESULTS

Approximately 1 % (N = 536,948) of all substance use treatment admissions in TEDS-A were for pregnant people. Between 1995 and 2021, the percentage of treatment admissions increased for primary methamphetamine use (10 % to 27 %), primary opioid use (21 % to 38 %), and primary cannabis use (9 % to 18 %), and decreased for primary cocaine use (32 % to 6 %) and primary alcohol use (26 % to 11 %). By 2021, treatment admissions referred from criminal legal agencies were more likely to primarily be for primary methamphetamine use (33 % vs 25 %) and less likely to be for primary opioid use (22 % vs 42 %) compared to other referral sources.

CONCLUSIONS

Trends in substance use treatment during pregnancy have changed substantially over the past few decades and emphasize the unique needs of patients referred to treatment by the criminal legal system. Treatment programs must therefore adapt to fluctuating trends in perinatal substance use. In particular, it is important to expand programs that prioritize treatment of methamphetamine use disorder for pregnant people referred through criminal legal agencies.

Ischemic Heart Disease in Pregnancy: Current Understanding and Management Strategies

Ischemic heart disease (IHD) during pregnancy poses a rare but significant risk to maternal and fetal health, with global incidence rates ranging from 0.7 to 10 cases per 100,000 pregnancies. This review synthesizes current literature on the epidemiology, pathophysiology, clinical presentation, diagnosis, management, and outcomes of IHD in pregnancy. Pregnancy-related IHD encompasses various conditions, including coronary artery disease, spontaneous coronary artery dissection, myocardial infarction with nonobstructive coronary arteries, coronary embolism, and coronary vasospasm. The pathophysiology is multifactorial, involving hemodynamic changes, hormonal influences, and increased hypercoagulability. Clinical presentation may mimic typical pregnancy symptoms, necessitating a high index of suspicion for timely diagnosis. A multidisciplinary strategy is needed for management, taking into account the hazards to the mother and fetus while also taking drug safety and procedural treatments such coronary artery bypass grafting and percutaneous coronary intervention into account. Careful observation and timely management are necessary for complications such as cardiogenic shock, arrhythmias, and thromboembolic events following myocardial infarction. With advancements in treatment techniques and early discovery, the prognosis has improved, although maternal mortality is still a worry. For the purpose of improving results and directing future research endeavors, knowledge and comprehension of IHD during pregnancy are essential.

Does reversible postpartum contraception reduce the risk of pregnancy condition recurrence? A longitudinal claims-based study from Maine

PURPOSE

To estimate the effect of reversible postpartum contraception use on the risk of recurrent pregnancy condition in the subsequent pregnancy and if this effect was mediated through lengthening the interpregnancy interval (IPI).

METHODS

We used data from the Maine Health Data Organization's Maine All Payer Claims dataset. Our study population was Maine women with a livebirth index pregnancy between 2007 and 2019 that was followed by a subsequent pregnancy starting within 60 months of index pregnancy delivery. We examined recurrence of three pregnancy conditions, separately, in groups that were not mutually exclusive: prenatal depression, hypertensive disorders of pregnancy (HDP), and gestational diabetes (GDM). Effective reversible postpartum contraception use was defined as any intrauterine device, implant, or moderately effective method (pills, patch, ring, injectable) initiated within 60 days of delivery. Short IPI was defined as ≤ 12 months. We used log-binomial regression models to estimate risk ratios and 95 % confidence intervals, adjusting for potential confounders.

RESULTS

Approximately 41 % (11,448/28,056) of women initiated reversible contraception within 60 days of delivery, the prevalence of short IPI was 26 %, and the risk of pregnancy condition recurrence ranged from 38 % for HDP to 55 % for prenatal depression. Reversible contraception initiation within 60 days of delivery was not associated with recurrence of the pregnancy condition in the subsequent pregnancy (aRR ranged from 0.97 to 1.00); however, it was associated with lower risk of short IPI (aRR ranged from 0.67 to 0.74).

CONCLUSION(S)

Although initiation of postpartum reversible contraception within 60 days of delivery lengthens the IPI, our findings suggest that it does not reduce the risk of prenatal depression, HDP, or GDM recurrence. This indicates a missed opportunity for providing evidence-based healthcare and health interventions in the intrapartum period to reduce the risk of recurrence.

Prescription medication use during pregnancy in the United States from 2011 to 2020: trends and safety evidence

BACKGROUND

Medication use during pregnancy has increased in the United States despite the lack of safety data for many medications.

OBJECTIVE

This study aimed to inform research priorities by examining trends in medication use during pregnancy and identifying gaps in safety information on the most commonly prescribed medications.

STUDY DESIGN

We identified population-based cohorts of commercially (MarketScan 2011-2020) and publicly (Medicaid Analytic eXtract/Transformed Medicaid Statistical Information System Analytic Files 2011-2018) insured pregnancies ending in live birth from 2 health care utilization databases. Medication use was based on filled prescriptions between the date of last menstrual period through delivery, as well as the period before the last menstrual period and during specific trimesters. We also included a cross-sectional representative sample of pregnancies ascertained by the National Health and Nutrition Examination Survey (2011-2020), with information on prescription medication use during the preceding month obtained through maternal interviews. Teratogen Information System was used to classify the available evidence on teratogenic risk.

RESULTS

Among over 3 million pregnancies, the medications most commonly dispensed at any time during pregnancy were analgesics, antibiotics, and antiemetics. The top medications were ondansetron (16.8%), amoxicillin (13.5%), and azithromycin (12.4%) in MarketScan, nitrofurantoin (22.2%), acetaminophen (21.3%; mostly as part of acetaminophen-hydrocodone products), and ondansetron (19.5%) in Medicaid Analytic eXtract/Transformed Medicaid Statistical Information System Analytic Files, and levothyroxine (5.0%), sertraline (2.9%), and insulin (2.9%) in the National Health and Nutrition Examination Survey group. The most commonly dispensed suspected teratogens during the first trimester were antithyroid medications. The use of antidiabetic and psychotropic medications has continued to increase in the United States during the last decade, opioid dispensation has decreased by half, and antibiotics and antiemetics continue to be common. For one-quarter of medications, there is insufficient evidence available to characterize their safety profile in pregnancy.

CONCLUSION

There is a need for more drug research in pregnant patients. Future research should focus on anti-infectives with high utilization and limited level of evidence on safety for use during pregnancy. Although lack of evidence is not evidence of safety concerns, it does not indicate risk either. In many instances, the benefits outweigh the risks when these medications are used clinically, and some of the medications with no proven safety may be necessary to treat patients.

Rural hospital and obstetric unit closures as social determinants of racial and ethnic maternal health disparities: A scoping review

AIMS

To synthesize literature examining (1) rural hospital or obstetric unit closures as a social determinant of maternal/infant health outcomes and (2) closures as a social determinant of racial/ethnic disparities in maternal/infant health outcomes.

DESIGN

Scoping review.

DATA SOURCES

MEDLINE, OVID/Embase and CINAHL were searched systematically to identify sources from 31 July 2003 to 31 July 2023. The Arksey and O'Malley methodology for scoping reviews was used.

RESULTS

Four studies from the United States and Australia documented the impact of rural hospital or obstetric unit closures on maternal/infant health outcomes, such as increased births in hospitals without obstetric units, out-of-hospital births or babies born before arrival, preterm birth, infant mortality and sociocultural risks that contribute to clinical risk. No eligible studies investigated hospital or obstetric unit closure as a social determinant of racial disparities in rural maternal/infant health outcomes.

CONCLUSION

Despite significant racial and ethnic rural maternal health disparities, associations between rural closures and maternal health outcomes for racial and ethnic minorities are understudied. More research is needed to understand the extent to which rural closures, a social determinant of health, could disproportionately, negatively affect the health of racially and ethnically minoritized women.

IMPLICATIONS FOR THE PROFESSION AND PATIENT CARE

Rural women have a greater risk of maternal and infant mortality and morbidity compared with urban women, and the impact of rural closures on racial and ethnic maternal health disparities is not well documented. Research about the impact of rural closures on maternal health disparities could inform policy to assure essential obstetric care is available for rural populations globally.

IMPACT

Findings provide a call to action for research to understand relationships between rural closures and racial and ethnic maternal health disparities, which is especially important for serving rural Non-Hispanic Black and American Indian/Alaska Native women.

PATIENT OR PUBLIC CONTRIBUTION

No patient or public contribution.

A biobehavioral observational study to understand the multilevel determinants of cardiovascular health in Black women: the BLOOM Study protocol

BACKGROUND

The racial/ethnic and gender disparities in cardiovascular disease (CVD) morbidity and mortality in the United States are evident. Across nearly every metric, non-Hispanic Black women have poorer overall cardiovascular health. Emerging evidence shows a disproportionately high burden of increased CVD risk factors in Black women of childbearing age, which has a far-reaching impact on both maternal and child outcomes, resulting in premature onset of CVD and further widens the racial disparities in CVD. There is growing recognition that the fundamental driver of persistent racial/ethnic disparities in CVD, as well as disparities in behavioral risk factors such as physical activity and sleep, is structural racism. Further, the lived personal experience of racial discrimination not only has a negative impact on health behaviors, but also links to various physiological pathways to CVD risks, such as internalized stress resulting in a pro-inflammatory state. Limited research, however, has examined the interaction between daily experience and health behaviors, which are influenced by upstream social determinants of health, and the downstream effect on biological/physiological indicators of cardiovascular health in non-pregnant Black women of childbearing age.

METHODS/DESIGN

The BLOOM Study is an observational study that combines real-time ambulatory assessments over a 10-day monitoring period with in-depth cross-sectional lab-based physiological and biological assessments. We will use a wrist-worn actigraphy device to capture 24-h movement behaviors and electronic ecological momentary assessment to capture perceived discrimination, microaggression, and stress. Blood pressure will be captured continuously through a wristband. Saliva samples will be self-collected to assess cortisol level as a biomarker of psychological stress. Lab assessments include a fasting venous blood sample, and assessment of various indices of peripheral and cerebral vascular function/health. Participants' address or primary residence will be used to obtain neighborhood-level built environmental and social environmental characteristics. We plan to enroll 80 healthy Black women who are between 18 and 49 years old for this study.

DISCUSSION

Results from this study will inform the development of multilevel (i.e., individual, interpersonal, and social-environmental levels) lifestyle interventions tailored to Black women based on their lived experiences with the goal of reducing CVD risk.

Temporal changes in pre-existing health conditions five years prior to pregnancy in British Columbia, Canada, 2000-2019

BACKGROUND

Pre-existing health conditions increase the risk of obstetric complications during pregnancy and birth. However, the prevalence and recent changes in the frequency of pre-existing health conditions in the childbearing population remain unknown.

OBJECTIVES

To estimate the temporal changes in the prevalence of pre-existing health conditions among pregnant women in British Columbia, Canada.

METHODS

We carried out a population-based cross-sectional study of 825,203 deliveries in BC between 2000 and 2019 and examined 17 categories of physical and psychiatric health conditions recorded within 5 years before childbirth. We also undertook age-period-cohort analyses to evaluate temporal changes in pre-existing health conditions.

RESULTS

The prevalence of any pre-existing health condition was 26.2% (n = 216,214) with overall trends remaining stable during the study period. Between 2000 and 2019, the prevalence rates of anxiety (5.6%-9.6%), bipolar (1.6%-3.4%), psychosis (0.7%-0.8%), and eating disorders (0.2%-0.3%) increased. The prevalence of hypertension increased sharply from 0.06% in 2000 to 0.3% in 2019. Diabetes mellitus and stroke rates increased, as did the prevalence of systemic lupus, multiple sclerosis, and chronic kidney disease. Advanced maternal age was strongly associated with both psychiatric and circulatory/metabolic conditions. A strong birth cohort effect was evident, with rates of psychiatric conditions increasing among women born after 1985.

CONCLUSIONS

In British Columbia, Canada, 1 in 4 mothers had a pre-existing health condition 5 years prior to pregnancy. These findings underscore the need for multi-disciplinary care for women with pre-existing health conditions to improve maternal, foetal, and infant health.

Postpartum Primary Care Engagement Using Default Scheduling and Tailored Messaging: A Randomized Clinical Trial

Importance

More than 30% of pregnant people have at least 1 chronic medical condition, and nearly 20% develop gestational diabetes or pregnancy-related hypertension, increasing the risk of future chronic disease. While these individuals are often monitored closely during pregnancy, they face major barriers when transitioning to primary care following delivery, due in part to a lack of health care support for this transition.

Objective

To evaluate the impact of an intervention designed to improve postpartum primary care engagement by reducing patient administrative burden and information gaps.

Design, Setting, and Participants

An individual-level randomized clinical trial was conducted from November 3, 2022, to October 11, 2023, at 1 hospital-based and 5 community-based outpatient obstetric clinics affiliated with a large academic medical center. Participants included English- and Spanish-speaking pregnant or recently postpartum adults with obesity, anxiety, depression, diabetes, chronic hypertension, gestational diabetes, or pregnancy-related hypertension and a primary care practitioner (PCP) listed in their electronic health record.

Intervention

A behavioral economics-informed intervention bundle, including default scheduling of postpartum PCP appointments and tailored messages.

Main Outcome and Measures

Completion of a PCP visit for routine or chronic condition care within 4 months of delivery was the primary outcome, ascertained directly by reviewing the patient's electronic health record approximately 5 months after their estimated due date. Intention-to-treat analysis was conducted.

Results

A total of 360 patients were randomized (control, 176; intervention, 184). Individuals had a mean (SD) age of 34.1 (4.9) years and median gestational age of 36.3 (IQR, 34.0-38.6) weeks at enrollment. The distribution of self-reported race and ethnicity was 6.8% Asian, 7.4% Black, 68.6% White, and 15.0% multiple races or other. Most participants (75.4%) had anxiety or depression, 16.1% had a chronic or pregnancy-related hypertensive disorder, 19.5% had preexisting or gestational diabetes, and 40.8% had a prepregnancy body mass index of 30 or greater. Medicaid was the primary payer for 21.2% of patients. Primary care practitioner visit completion within 4 months occurred in 22.0% (95% CI, 6.4%-28.8%) of individuals in the control group and 40.0% (95% CI, 33.1%-47.4%) in the intervention group. In regression models accounting for randomization strata, the intervention increased PCP visit completion by 18.7 percentage points (95% CI, 9.1-28.2 percentage points). Intervention participants also had fewer postpartum readmissions (1.7% vs 5.8%) and increased receipt of the following services by a PCP: blood pressure screening (42.8% vs 28.3%), weight assessment (42.8% vs 27.7%), and depression screening (32.8% vs 16.8%).

Conclusions and Relevance

The findings of this randomized clinical trial suggest that the current lack of support for postpartum transitions to primary care is a missed opportunity to improve recently pregnant individual's short- and long-term health. Reducing patient administrative burdens may represent relatively low-resource, high-impact approaches to improving postpartum health and well-being.

Changes in the prevalence of maternal chronic conditions during pregnancy: A nationwide age-period-cohort analysis

OBJECTIVE

To estimate temporal changes in the prevalence of pre-existing chronic conditions among pregnant women in Sweden and evaluate the extent to which secular changes in maternal age, birth cohorts and obesity are associated with these trends.

DESIGN

Population-based cross-sectional study.

SETTING

Sweden, 2002-2019.

POPULATION

All women (aged 15-49 years) who delivered in Sweden (2002-2019).

METHODS

An age-period-cohort analysis was used to evaluate the effects of age, calendar periods, and birth cohorts on the observed temporal trends.

MAIN OUTCOME MEASURES

Pre-existing chronic conditions, including 17 disease categories of physical and psychiatric health conditions recorded within 5 years before childbirth, presented as prevalence rates and rate ratios (RRs) with 95% confidence intervals (CIs). Temporal trends were also adjusted for pre-pregnancy body mass index (BMI) and the mother's country of birth.

RESULTS

The overall prevalence of at least one pre-existing chronic condition was 8.7% (147 458 of 1 703 731 women). The rates of pre-existing chronic conditions in pregnancy increased threefold between 2002-2006 and 2016-2019 (RR 2.82, 95% CI 2.77-2.87). Rates of psychiatric (RR 3.80, 95% CI 3.71-3.89), circulatory/metabolic (RR 1.62, 95% CI 1.55-1.71), autoimmune/neurological (RR 1.69, 95% CI 1.61-1.78) and other (RR 2.10, 95% CI 1.99-2.22) conditions increased substantially from 2002-2006 to 2016-2019. However, these increasing rates were less pronounced between 2012-2015 and 2016-2019. No birth cohort effect was evident for any of the pre-existing chronic conditions. Adjusting for secular changes in obesity and the mother's country of birth did not affect these associations.

CONCLUSIONS

The burden of pre-existing chronic conditions in pregnancy in Sweden increased from 2002 to 2019. This increase may be associated with the improved reporting of diagnoses and advancements in chronic condition treatment among women, potentially enhancing their fecundity.

Racial Disparities in Medication Use During Pregnancy: Results from the NISAMI Cohort

Purpose

This study aimed to evaluate racial disparities in medication use and associated factors among pregnant women receiving prenatal care at Brazilian Unified Health System primary care health units in the northeast region.

Patients and Methods

A total of 1058 pregnant women in the NISAMI Cohort were interviewed between June 2012 and February 2014. Medicines used during pregnancy were classified according to the Anatomical Therapeutic Chemical (ATC) classification system and ANVISA pregnancy risk categories. Prevalence ratios (crude and adjusted) and 95% confidence intervals (CIs) were estimated using Poisson regression with robust error variance. All analyses were stratified by race (Asian, black, brown/mixed, Brazilian indigenous, and white).

Results

Approximately 84% of the pregnant women used at least one medication, with a lower proportion among white women. The most reported medications were antianemic preparations (71.08%; 95% CI 68.27-73.72%), analgesics (21.74%; 95% CI 19.36-24.32%), and drugs for functional gastrointestinal disorders (18.81%; 95% CI 16.57-21.28%). Approximately 29% of women took potentially risky medications during pregnancy, with a higher prevalence among Asian and white women. Factors associated with medication use during pregnancy include a greater number of prenatal consultations, higher education levels, health problems, and smoking. In addition, maternal age above 25 years, smoking status, and two or more previous pregnancies were associated with potentially risky medication use during pregnancy.

Conclusion

A high prevalence of medication use during pregnancy was found; however, this prevalence was lower among white women. Nonetheless, black and brown women used antianemic preparations less frequently. This finding suggests that race is a factor of inequity in prenatal care, demanding public policies to mitigate it.

Assessing the relationship between census tract rurality and severe maternal morbidity in California (1997-2018)

PURPOSE

Recent studies have demonstrated an increased risk of severe maternal morbidity (SMM) for people living in rural versus urban counties. Studies have not considered rurality at the more nuanced subcounty census-tract level. This study assessed the relationship between census-tract-level rurality and SMM for birthing people in California.

METHODS

We used linked vital statistics and hospital discharge records for births between 1997 and 2018 in California. SMM was defined by at least 1 of 21 potentially fatal conditions and lifesaving procedures. Rural-Urban Commuting Area codes were used to characterize census tract rurality dichotomously (2-category) and at 4 levels (4-category). Covariates included sociocultural-demographic, pregnancy-related, and neighborhood-level factors. We ran a series of mixed-effects logistic regression models with tract-level clustering, reporting risk ratios and 95% confidence intervals (CIs). We used the STROBE reporting guidelines.

FINDINGS

Of 10,091,415 births, 1.1% had SMM. Overall, 94.3% of participants resided in urban/metropolitan and 5.7% in rural tracts (3.9% micropolitan, 0.9% small town, 0.8% rural). In 2-category models, the risk of SMM was 10% higher for birthing people in rural versus urban tracts (95% CI: 6%, 13%). In 4-category models, the risk of SMM was 16% higher in micropolitan versus metropolitan tracts (95% CI: 12%, 21%).

CONCLUSION

The observed rurality and SMM relationship was driven by living in a micropolitan versus metropolitan tract. Increased risk may result from resource access inequities within suburban areas. Our findings demonstrate the importance of considering rurality at a subcounty level to understand locality-related inequities in the risk of SMM.

Severe Maternal Morbidity among Low-Income Patients with Hypertensive Disorders of Pregnancy

OBJECTIVE

Hypertensive disorders of pregnancy (HDP) contribute significantly to the development of severe maternal morbidities (SMM), particularly among low-income women. The purpose of the study was to explore the relationship between maternal characteristics and SMM, and to investigate if differences in SMM exist among patients with HDP diagnosis.

STUDY DESIGN

This study utilized 2017 Alabama Medicaid administrative claims. SMM diagnoses were captured using the Centers for Disease Control and Prevention's classification by International Classification of Diseases codes. Maternal characteristics and frequencies were compared using Chi-square and Cramer's V statistics. Logistic regression analyses were conducted to examine multivariable relationships between maternal characteristics and SMM among patients with HDP diagnosis. Odds ratios and 95% confidence intervals (CIs) were used to estimate risk.

RESULTS

A higher proportion of patients experiencing SMM were >34 years old, Black, Medicaid for Low-Income Families eligible, lived in a county with greater Medicaid enrollment, and entered prenatal care (PNC) in the first trimester compared with those without SMM. Almost half of patients (46.2%) with SMM had a HDP diagnosis. After controlling for maternal characteristics, HDP, maternal age, county Medicaid enrollment, and trimester PNC entry were not associated with SMM risk. However, Black patients with HDP were at increased risk for SMM compared with White patients with HDP when other factors were taken into account (adjusted odds ratio [aOR] = 1.37, 95% CI: 1.11-1.69). Patients with HDP and SMM were more likely to have a prenatal hospitalization (aOR = 1.45, 95% CI: 1.20-1.76), emergency visit (aOR = 1.30, 95% CI: 1.07-1.57), and postpartum cardiovascular prescription (aOR = 2.43, 95% CI: 1.95-3.04).

CONCLUSION

Rates of SMM differed by age, race, Medicaid income eligibility, and county Medicaid enrollment but were highest among patients with clinical comorbidities, especially HDP. However, among patients with HDP, Black patients had an elevated risk of severe morbidity even after controlling for other characteristics.

KEY POINTS

· Patients with SMM were more likely to have a HDP diagnosis.. · Among those with HDP, Black patients had elevated risk of SMM.. · Differences in care delivery did not explain SMM disparities..

Increasing Postpartum Primary Care Engagement through Default Scheduling and Tailored Messaging: A Randomized Clinical Trial

Importance

Over 30% of pregnant people have at least one chronic medical condition, and nearly 20% develop gestational diabetes or pregnancy-related hypertension, increasing the risk of future chronic disease. While these individuals are often monitored closely during pregnancy, they face significant barriers when transitioning to primary care following delivery, due in part to a lack of health care support for this transition.

Objective

To evaluate the impact of an intervention designed to improve postpartum primary care engagement by reducing patient administrative burden and information gaps.

Design

Individual-level randomized controlled trial conducted from November 3, 2022 to October 11, 2023.

Setting

One hospital-based and five community-based outpatient obstetric clinics affiliated with a large academic medical center.

Participants

Participants included English- and Spanish-speaking pregnant or recently postpartum adults with obesity, anxiety, depression, diabetes mellitus, chronic hypertension, gestational diabetes, or pregnancy-related hypertension, and a primary care practitioner (PCP) listed in their electronic health record (EHR).

Intervention

A behavioral economics-informed intervention bundle, including default scheduling of postpartum PCP appointments and tailored messages.

Main Outcome

Completion of a PCP visit for routine or chronic condition care within 4 months of delivery.

Results

360 patients were randomized (Control: N=176, Intervention: N=184). Individuals had mean (SD) age 34.1 (4.9) years and median gestational age of 36.3 weeks (interquartile range (IQR) 34.0-38.6 weeks) at enrollment. The distribution of self-reported races was 7.4% Asian, 6.8% Black, 15.0% multiple races or "Other," and 68.6% White. Most (75.8%) participants had anxiety or depression, 15.9% had a chronic or pregnancy-related hypertensive disorder, 19.8% had pre-existing or gestational diabetes, and 40.4% had a pre-pregnancy BMI ≥30 kg/m2. Medicaid was the primary payer for 21.9% of patients. PCP visit completion within 4 months occurred in 22.0% in the control group and 40.0% in the intervention group. In regression models accounting for randomization strata, the intervention increased PCP visit completion by 18.7 percentage points (95%CI 10.7-29.1). Intervention participants also had fewer postpartum readmissions (1.7 vs. 5.8%) and increased receipt of the following services by a PCP: blood pressure screening (42.8 vs. 28.3%), weight assessment (42.8 vs. 27.7%), and depression screening (32.8 vs. 16.8%).

Conclusions and Relevance

In this randomized trial of pregnant individuals with or at risk for chronic health conditions, default PCP visit scheduling, tailored messages, and reminders substantially improved postpartum primary care engagement. The current lack of support for postpartum transitions to primary care is a missed opportunity to improve recently pregnant individual's short- and long-term health. Reducing patient administrative burdens may represent relatively low-resource, high-impact approaches to improving postpartum health and wellbeing.

Disparities in Utilization and Delivery Outcomes for Women with Perinatal Mood and Anxiety Disorders

Perinatal mood and anxiety disorders (PMAD), which include depression and/or anxiety in the year before and/or after delivery, are common complications of pregnancy, affecting up to one in four perinatal individuals, with costs of over $15 billion per year in the US. In this paper, we provide an overview of the disparities in utilization and delivery outcomes for individuals with perinatal mood and anxiety disorders in the US. In addition, we discuss the current US screening and treatment guidelines as well as the high societal costs of illness of PMAD for both perinatal individuals and children. Finally, we outline opportunities for quality improvement of PMAD care in the US, including leveraging increased engagement with healthcare system during prenatal care, working toward a more cohesive national strategy to address PMAD, leaning into evidence-based policymaking through collaboration with a panel of experts, and generating state-level profiles focused on PMAD.

Trends and Disparities in Perinatal Opioid Use Disorder Treatment in Medicaid, 2007-2012

We described Medicaid-insured women by receipt of perinatal opioid use disorder (OUD) treatment; and trends and disparities in treatment. Using 2007 to 2012 Medicaid Analytic eXtract data from 45 states and D.C., we identified deliveries among women with OUD. Regressions modeled the association between patient characteristics and receipt of any OUD treatment, medication for OUD (MOUD), and counseling alone during the perinatal period. Rates of any OUD treatment and MOUD for women with perinatal OUD increased over the study period, but trends differed by subgroup. Compared with non-Hispanic White women, Black and American Indian/Alaskan Native (AI/AN) women were less likely to receive any OUD treatment, and Black women were less likely to receive MOUD. Over time, the disparity in receipt of MOUD between Black and White women increased. Overall gains in OUD treatment were driven by improvements in perinatal OUD care for White women and obscured disparities for Black and AI/AN women.

Patterns of multiple chronic conditions in pregnancy: Population-based study using latent class analysis

BACKGROUND

Adults with multiple chronic conditions (MCC) are a heterogeneous population with elevated risk of future adverse health outcomes. Yet, despite the increasing prevalence of MCC globally, data about MCC in pregnancy are scarce.

OBJECTIVES

To estimate the population prevalence of MCC in pregnancy and determine whether certain types of chronic conditions cluster together among pregnant women with MCC.

METHODS

We conducted a population-based cohort study in Ontario, Canada, of all 15-55-year-old women with a recognised pregnancy, from 2007 to 2020. MCC was assessed from a list of 22 conditions, identified using validated algorithms. We estimated the prevalence of MCC. Next, we used latent class analysis to identify classes of co-occurring chronic conditions in women with MCC, with model selection based on parsimony, clinical interpretability and statistical fit.

RESULTS

Among 2,014,508 pregnancies, 324,735 had MCC (161.2 per 1000, 95% confidence interval [CI] 160.6, 161.8). Latent class analysis resulted in a five-class solution. In four classes, mood and anxiety disorders were prominent and clustered with one additional condition, as follows: Class 1 (22.4% of women with MCC), osteoarthritis; Class 2 (23.7%), obesity; Class 3 (15.8%), substance use disorders; and Class 4 (22.1%), asthma. In Class 5 (16.1%), four physical conditions clustered together: obesity, asthma, chronic hypertension and diabetes mellitus.

CONCLUSIONS

MCC is common in pregnancy, with sub-types dominated by co-occurring mental and physical health conditions. These data show the importance of preconception and perinatal interventions, particularly integrated care strategies, to optimise treatment and stabilisation of chronic conditions in women with MCC.

Acceptability of Dyad Care Management After Preterm Birth: A Qualitative Study

OBJECTIVES

Care management programs for medically complex infants interact with parents after complicated pregnancies, when gaps in maternal health care are well documented. These care managers may have the relationships and skills to promote postpartum and interconception health and health care access. It is unknown whether expanding these care management models to address maternal needs would be acceptable.

METHODS

We conducted qualitative interviews with women with a history of preterm birth and clinicians. For women with a history of preterm birth, additional inclusion criteria were Medicaid-insured infant in one health system and English proficiency. We purposively oversampled women whose infants received care management. Clinicians worked in two geographically adjacent health systems. Interviews explored priorities after preterm birth and perceived acceptability of mother-infant dyad care management. Interviews were audio recorded, transcribed, and coded following an integrated approach in which we applied a priori codes and captured emergent themes.

RESULTS

We interviewed 33 women (10/2018-7/2021) and 24 clinicians (3/2021-8/2021). Women were predominantly non-Hispanic Black, and 15 had infants receiving care management. Clinicians included physicians, nurses, and social workers from Pediatrics, Obstetrics, and Family Medicine. Subgroups converged thematically, finding care management acceptable. Tailoring programs to address stress and sleep, emphasizing care managers with strong interpersonal skills and shared experiences with care management users, and program flexibility would contribute to acceptability.

CONCLUSIONS FOR PRACTICE

Dyad care management after preterm birth is acceptable to potential program end-users and clinicians. Dyad health promotion may contribute to improved birth outcomes, infant, and parent health.

Disparities in Perinatal and Emergency Care Receipt Among Women With Perinatal Opioid Use Disorder in Medicaid, 2007 to 2012

OBJECTIVES

This study aimed to better understand receipt of perinatal and emergency care among women with perinatal opioid use disorder (OUD) and explore variation by race/ethnicity.

METHODS

We used 2007-2012 Medicaid Analytic eXtract (MAX) data from all 50 states and the District of Columbia to examine 6,823,471 deliveries for women 18 to 44 years old. Logistic regressions modeled the association between (1) OUD status and receipt of perinatal and emergency care, and (2) receipt of perinatal and emergency care and race/ethnicity, conditional on OUD diagnosis and controlling for patient and county characteristics. We used robust SEs, clustered at the individual level, and included state and year fixed effects.

RESULTS

Women with perinatal OUD were less likely to receive adequate prenatal care (adjusted odds ratio [aOR], 0.45; 95% confidence interval [CI], 0.44-0.46) and attend the postpartum visit (aOR, 0.46; 95% CI, 0.45-0.47) and more likely to seek emergency care (aOR, 1.48; 95% CI, 1.45-1.51) than women without perinatal OUD. Among women with perinatal OUD, Black, Hispanic, and American Indian and Alaskan Native (AI/AN) women were less likely to receive adequate prenatal care (aOR, 0.68 [95% CI, 0.64-0.72]; aOR, 0.86 [95% CI, 0.80-0.92]; aOR, 0.71 [95% CI, 0.64-0.79]) and attend the postpartum visit (aOR, 0.85 [95% CI, 0.80-0.91]; aOR, 0.86 [95% CI, 0.80-0.93]; aOR, 0.83 [95% CI, 0.73-0.94]) relative to non-Hispanic White women. Black and AI/AN women were also more likely to receive emergency care (aOR, 1.13 [95% CI, 1.05-1.20]; aOR, 1.12 [95% CI, 1.00-1.26]).

CONCLUSIONS

Our findings suggest that women with perinatal OUD, in particular Black, Hispanic, and AI/AN women, may be missing opportunities for preventive care and comprehensive management of their physical and behavioral health during pregnancy.

Associations of cesarean sections with comorbidities within the Pregnancy Risk Assessment Monitoring System

OBJECTIVES

Cesarean delivery (CD) is a common obstetrical procedure aimed at reducing maternal and infant morbidity and mortality in complicated pregnancies and medical emergencies yet carries potential complications. CD rates in the USA have increased over the years - likely associated with increased comorbidities. Thus, to expand the literature, our objective was to identify the likelihood of a woman having a CD when comorbidities - diabetes, high blood pressure (HBP), or depression - are present.

METHODS

We conducted a cross-sectional analysis of the 2019 Pregnancy Risk Assessment Monitoring System. Binary and multivariable logistic regression were used to calculate adjusted odds ratios (AORs) to determine associations between pre-existing and gestational comorbidities and CD among pregnant women.

RESULTS

Compared to those without a diagnosis, women with pre-existing diabetes (AOR: 1.69; CI: 1.54-1.86), pre-existing HBP (AOR: 1.58; CI: 1.46-1.69), and pre-existing depression (AOR: 1.14; CI 1.08-1.20; Table 2) were more likely to have a CD. Additionally, participants with gestational diabetes (AOR 1.43; CI 1.34-1.52), HBP (AOR 1.86; CI 1.76-1.95) and depression (AOR 1.13; CI 1.07-1.19) were also more likely to have a CD than those without comorbidities.

CONCLUSIONS

Higher rates of CD were found among individuals with a pre-existing or gestational diagnosis of diabetes, HBP, or depression than those without these diagnoses. With increasing rates of these conditions, it is likely that CD rates will continue their trajectory in the USA. Thus, professional organizations can have more impact by popularizing and making effective evidence-based guidelines for management.

Chronic Hypertension in Pregnancy and Racial-Ethnic Disparities in Complications

OBJECTIVE

To evaluate whether there are individual- and population-level associations between chronic hypertension and pregnancy complications, and to assess differences across seven racial-ethnic groups.

METHODS

This population-based study used linked vital statistics and hospitalization discharge data from all live and stillbirths in California (2008-2018), Michigan (2008-2020), Oregon (2008-2020), Pennsylvania (2008-2014), and South Carolina (2008-2020). We used multivariable log-binomial regression models to estimate risk ratios (RRs) and population attributable risk (PAR) percentages with 95% CIs for associations between chronic hypertension and several obstetric and neonatal outcomes, selected based on prior evidence and pathologic pathways. We adjusted models for demographic factors (race and ethnicity, payment method, educational attainment), age, body mass index, obstetric history, delivery year, and state, and conducted analyses stratified across seven racial-ethnic groups.

RESULTS

The study included 7,955,713 pregnancies, of which 168,972 (2.1%) were complicated by chronic hypertension. Chronic hypertension was associated with several adverse obstetric and neonatal outcomes, with the largest adjusted PAR percentages observed for preeclampsia with severe features or eclampsia (22.4; 95% CI 22.2-22.6), acute renal failure (13.6; 95% CI 12.6-14.6), and pulmonary edema (10.7; 95% CI 8.9-12.6). Estimated RRs overall were similar across racial-ethnic groups, but PAR percentages varied. The adjusted PAR percentages (95% CI) for severe maternal morbidity-a widely used composite of acute severe events-for people who were American Indian or Alaska Native, Asian, Black, Latino, Native Hawaiian or Other Pacific Islander, White, and Multiracial or Other were 5.0 (1.1-8.8), 3.7 (3.0-4.3), 9.0 (8.2-9.8), 3.9 (3.6-4.3), 11.6 (6.4-16.5), 3.2 (2.9-3.5), and 5.5 (4.2-6.9), respectively.

CONCLUSION

Chronic hypertension accounts for a substantial fraction of obstetric and neonatal morbidity and contributes to higher complication rates, particularly for people who are Black or Native Hawaiian or Other Pacific Islander.

The Influence of Racial/Ethnic and Gender Concordance on Care Among Non-Pregnant Women of Childbearing Age with Diabetes Mellitus: an Analysis of the Medical Expenditure Panel Survey, 2010-2019

INTRODUCTION

This study examined associations between patient-provider race/ethnicity concordance and gender concordance on overall healthcare ratings, self-efficacy, and diabetes care monitoring in non-pregnant women of childbearing age with diabetes mellitus before and after adjusting for sociodemographic factors.

METHODS

We analyzed longitudinal data from the 2010-2019 Medical Expenditure Panel Survey. The sample was limited to non-pregnant women of childbearing age (18-45 years) diagnosed with diabetes (unweighted n = 327; weighted n = 566,504). Bivariate analysis, logistic regression, and latent variable modeling were performed.

RESULTS

Few racially minoritized women reported racial/ethnic and gender concordance with their healthcare provider. Only 2.9% of Hispanic women reported having a Hispanic provider and 12.1% of non-Hispanic Black women reported seeing a non-Hispanic Black provider compared to 81.1% of non-Hispanic White women who reported seeing a non-Hispanic White provider (p < .0001). Among Hispanic women, 15.3% reported seeing a female provider compared to 25.2% of non-Hispanic Black and 53.5% of non-Hispanic White women. Patient-provider race/ethnicity and gender concordance were not statistically significantly associated with overall healthcare ratings, self-efficacy, or diabetes care monitoring.

CONCLUSIONS

This study revealed a large disparity in race/ethnicity and gender concordance among minority women of reproductive age with diabetes compared to their non-Hispanic White counterparts. There is a need for larger, more robust studies to examine the influence of provider and other healthcare characteristics on diabetes-related outcomes in this understudied population.

Role of Maternal Age in Increasing Severe Maternal Morbidity Rates in the United States

OBJECTIVE

To evaluate a commonly proposed explanation for increasing rates of severe maternal morbidity (SMM) in the United States: shifts in the birthing population to older maternal ages, a known risk factor for SMM.

METHODS

We conducted a cross-sectional analysis comparing delivery hospitalizations from two time points (2008-2009 to 2017-2018) using hospital discharge data from the National Inpatient Sample. We used demographic decomposition techniques to evaluate whether increasing rates of SMM and nontransfusion SMM were explained by population-level increases in maternal age or changes in age-specific rates. Analyses were stratified by race and ethnicity.

RESULTS

Rates of SMM and nontransfusion SMM significantly increased in the United States between 2008 and 2018 from 135.6 to 170.5 and 58.8 to 67.9 per 10,000 delivery hospitalizations, respectively, with increases observed for nearly all racial and ethnic groups. Over this same period, the proportion of births to people younger than age 25 years decreased and births to people of advanced maternal age (35 years and older) increased, with the largest increases occurring among people identified as non-Hispanic American Indian/Alaskan Native (9.8-13.0%), non-Hispanic Black (10.7-14.4%), and Hispanic (12.1-17.1%). Decomposition analyses indicated that the changing maternal age distribution had little effect on SMM trends. Rather, increases in SMM and nontransfusion SMM were primarily driven by increases in age-specific SMM rates, including rising rates among younger people. Contributions of maternal age shifts were minimal for all racial and ethnic groups except among non-Hispanic Black people, for which 17-34% of the rise in SMM was due to increasing maternal age.

CONCLUSION

Except among certain racial groups, increases in U.S. population-level SMM rates over the past decade were due to increases in age-specific rates rather than shifts to older maternal age among the birthing population. Increasing SMM rates across the maternal age spectrum could indicate worsening prepregnancy health status of the birthing population.

A mixed methods systematic review of midwives' clinical practices related to prenatal care of women with obesity

OBJECTIVE

Maternal obesity has been related to adverse maternal and infant outcomes. It is a persistent challenge of midwifery care worldwide and can present clinical challenges and complications. This review sought to identify evidence on the practice patterns of midwives related to prenatal care of women with obesity.

METHODS

The databases Academic Search Premier, APA PsycInfo, CINAHL PLUS with Full Text, Health Source: Nursing/Academic Edition, and MEDLINE were searched November 2021. Search terms included weight, obesity, practices, and midwives. Inclusion criteria included quantitative, qualitative, and mixed method studies that addressed practice patterns of midwives related to prenatal care of women with obesity published in peer-reviewed journals, written in English. The recommended Joanna Briggs Institute approach to mixed methods systematic reviews was followed e.g. study selection, critical appraisal, data extraction, and a convergent segregated method of data synthesis and integration.

RESULTS

Seventeen articles from 16 studies were included. The quantitative evidence showed a lack of knowledge, confidence, and support for midwives that would facilitate adequate management of pregnant women with obesity while the qualitative evidence revealed that midwives desire a sensitive approach to discussing obesity and the risks associated with maternal obesity.

DISCUSSION

Quantitative and qualitative literature report consistent individual and system-level barriers to implementing evidence-based practices. Implicit bias training, midwifery curriculum updates, and the use of patient centered care models may help overcome these challenges.

Racial Disparities in Severe Maternal Morbidity in an Integrated Health Care System, Southern California, 2008-2017

OBJECTIVE

The study's objectives were to examine rates of severe maternal morbidity (SMM) over a 10-year period and assess racial/ethnic disparities in SMM among insured women in a large, integrated health care system in Southern California.

METHODS

We included Kaiser Permanente Southern California (KPSC) health plan members who gave birth at ≥20 weeks' gestation in a KPSC-owned hospital during 2008-2017. An SMM case was defined as presence of one or more indicators of an SMM event during a birth hospitalization, identified using maternal electronic health records. Crude SMM rates/10,000 births were calculated by year and maternal race/ethnicity. Modified Poisson regression models were used to assess the association between race/ethnicity and SMM adjusted for other maternal demographics, pregnancy characteristics, and preexisting conditions.

RESULTS

We identified 5,915 SMM cases among 335,310 births. Crude SMM rates increased from 94.7 per 10,000 in 2008 to 192.6 in 2015 and 249.5 in 2017. Non-Hispanic Black (adjusted risk ratio [aRR] 1.52; 95% confidence interval [CI] 1.37-1.69), Asian/Pacific Islander (aRR 1.29, 95% CI 1.18-1.41), and Hispanic (aRR 1.18, 95% CI 1.10-1.27) women had greater likelihood of SMM than non-Hispanic White women. After further adjusting for preexisting health conditions, differences in SMM by race/ethnicity remained.

CONCLUSIONS

SMM rates increased during 2008-2017 and women of racial and ethnic minority groups, particularly non-Hispanic Black women, were more likely to experience an SMM event than non-Hispanic White women. Multilevel approaches to understanding structural and social factors that may be associated with racial and ethnic disparities in SMM are needed to develop and test effective interventions to reduce SMM.

Abortion Access and Medically Complex Pregnancies Before and After Texas Senate Bill 8

OBJECTIVE

To evaluate how Texas health care professionals who care for patients experiencing medically complex pregnancies navigate abortion restrictions.

METHODS

We conducted qualitative in-depth interviews with health care professionals across Texas who cared for patients with life-limiting fetal diagnoses or who had existing or developed health conditions that adversely affected pregnancy. We conducted the first round of interviews March-June 2021 and the second round of interviews January-May 2022 after the implementation of Texas Senate Bill 8 (SB8), which prohibited most abortions after detection of embryonic cardiac activity. We used inductive and deductive qualitative analysis to identify themes and changes in practice after the implementation of SB8.

RESULTS

We conducted a total of 50 interviews: 25 before implementation of SB8 and 25 after the law's implementation. We interviewed 21 maternal-fetal medicine specialists, 19 obstetrician-gynecologists, eight physicians whose primary practice is the provision of abortion care, and two genetic counselors. Participants reported presenting their patients with information about health risks and outcomes of continued pregnancy in each policy period; however, counseling on these options was curtailed after implementation of SB8. Even in cases in which a patient's health and, in some cases, life would be compromised, narrow criteria for abortions at hospitals limited care before implementation of SB8, and criteria often became more stringent after implementation of SB8. Administrative approval processes and referrals for abortion delayed care and endangered patients' health, which worsened after in-state options were eliminated after implementation of SB8. Participants noted that patients with more limited resources who were unable to travel out of state often had to continue pregnancies, further increasing their risk of morbidity.

CONCLUSION

Texas health care professionals' abilities to provide evidence-based abortion care to patients with medically complex pregnancies were constrained by institutional policies, and care options narrowed further after implementation of SB8. Abortion restrictions limit shared decision making, compromise patient care, and put pregnant people's health at risk.

Pregnancy, Fetal, and Neonatal Outcomes Among Women With Traumatic Brain Injury

OBJECTIVE

There have been no systematic studies of pregnancy outcomes among women with traumatic brain injury (TBI), potentially limiting informed clinical care for women with such injuries. The purpose of this exploratory study was to evaluate pregnancy and fetal/neonatal outcomes among women with a TBI diagnosis recorded during their delivery hospitalization compared with women without TBI.

SETTING

In this cross-sectional study, we identified women with delivery hospitalizations using 2004-2014 data from the Nationwide Inpatient Sample of the Health Care and Cost Utilization Project.

PARTICIPANTS

We identified deliveries to women with a TBI diagnosis on hospital discharge records, which included all diagnoses recorded during the delivery, and compared them with deliveries of women without a TBI diagnosis.

MAIN MEASURES

Pregnancy outcomes included gestational diabetes; preeclampsia/eclampsia; placental abruption; cesarean delivery; and others. Fetal/neonatal outcomes included preterm birth; stillbirth; and small or large gestational age.

DESIGN

We modeled risk for each outcome among deliveries to women with TBI compared with women without TBI, using multivariate Poisson regression. Models included sociodemographic and hospital characteristics; secondary models added clinical characteristics (eg, psychiatric disorders) that may be influenced by TBI.

RESULTS

We identified 3 597 deliveries to women with a TBI diagnosis and 9 106 312 deliveries to women without TBI. Women with TBI were at an increased risk for placental abruption (relative risk [RR] = 2.73; 95% CI, 2.26-3.30) and associated sequelae (ie, antepartum hemorrhage, cesarean delivery). Women with TBI were at an increased risk for stillbirth (RR = 2.55; 95% CI, 1.97-3.29) and having a baby large for gestational age (RR = 1.30; 95% CI, 1.09-1.56). Findings persisted after controlling for clinical characteristics.

CONCLUSIONS

Risk for adverse pregnancy outcomes, including placental abruption and stillbirth, were increased among women with TBI. Future research is needed to examine the association between TBI and pregnancy outcomes using longitudinal and prospective data and to investigate potential mechanisms that may heighten risk for adverse outcomes.

Supporting reproductive health among birthing persons with chronic conditions in the United States: A qualitative multilevel study using systems thinking to inform action

OBJECTIVE (STUDY QUESTION)

To use systems thinking with diverse system actors to (a) characterize current problems at the intersection of chronic conditions (CCs) and reproductive health (RH) care and their determinants, (b) determine necessary system actors for change, and (c) document cross-system actions that can improve identified problems in the United States.

DATA SOURCES/STUDY SETTING

Data were collected from six groups of system actors via online focus groups.

STUDY DESIGN

This is a qualitative multilevel study using the iceberg systems thinking framework.

DATA COLLECTION/EXTRACTION METHODS

Data were collected by note-taking and recording six focus groups; analysis incorporated perspective triangulation using the systems thinking iceberg and system mapping to visualize interconnected system challenges, actors, and action ideas.

PRINCIPAL FINDINGS

Participants described eight necessary system actors: health care institutions, medical leaders, medical providers, patient advocates and foundations, patients and families, payors, policy makers, and research funders. Forty pain points were identified, spread across each of the four levels of the systems thinking iceberg: undesirable outcomes (6), concerning trends (9), system structure flaws (15), and problematic mental models (10). In response to these pain points, a set of 46 action ideas was generated by participants and mapped into nine action themes: (1) adjust QI metrics, incentives, and reimbursement, (2) bolster RH medical education and training, (3) break down medical silos, (4) enrich patient education, (5) expand the health care team, (6) improve holistic health care, (7) modify research and programmatic funding to prioritize RH and CC, (8) spur innovation for patient visits, and (9) support professional champions and leaders.

CONCLUSIONS

By embracing system complexity, creating visual maps, and pushing participants to identify actionable strategies for improvement, this study generates a set of specific actions that can be used to address pain points across the multiple system levels that make improving reproductive care for people with CCs so challenging.

Does Delayed Fertility Explain the Rise in Comorbidities Among the Birthing Population?

Background: The increasing prevalence of preexisting health conditions among pregnant people is often attributed to the concurrent rise in maternal age. However, the link between advanced maternal age (AMA) and increases in chronic conditions among the birthing population has not been systematically documented at the population level. Materials and Methods: This retrospective population-based cohort study was based on linked hospitalization discharge and birth certificate data for live birth deliveries in California from 1991 to 2012. Decomposition techniques evaluated whether changes in the prevalence of selected preexisting health conditions during delivery (autoimmune conditions, chronic hypertension, cardiac disease, diabetes, and renal disease) were explained by population-level increases in maternal age. Analyses further adjusted for maternal education, plurality, insurance status, and availability of paternal information on the birth certificate. Results: Between 1991 and 2012, there were more than 11.5 million live birth deliveries in California. AMA (≥35 years) increased nearly 70% over this period. The prevalence of autoimmune conditions, chronic hypertension, diabetes, and renal disease rose among the birthing population, while cardiac disease declined. The prevalence of all conditions was higher for AMA, but changes in maternal age accounted for only 5.3%, 8.4%, 13.9%, and 0.4%, of the increase in autoimmune conditions, chronic hypertension, diabetes, and renal disease, respectively. Conclusion: While AMA was associated with higher rates of preexisting health conditions, it contributed little to the increase in autoimmune conditions, chronic hypertension, and diabetes and nothing to the rise in renal disease during childbirth.

Interventions to enhance medication adherence in pregnancy- a systematic review

BACKGROUND

Sub-optimal medication adherence in pregnant women with chronic disease and pregnancy-related indications has the potential to adversely affect maternal and perinatal outcomes. Adherence to appropriate medications is advocated during and when planning pregnancy to reduce risk of adverse perinatal outcomes relating to chronic disease and pregnancy-related indications. We aimed to systematically identify effective interventions to promote medication adherence in women who are pregnant or planning to conceive and impact on perinatal, maternal disease-related and adherence outcomes.

METHODS

Six bibliographic databases and two trial registries were searched from inception to 28th April 2022. We included quantitative studies evaluating medication adherence interventions in pregnant women and women planning pregnancy. Two reviewers selected studies and extracted data on study characteristics, outcomes, effectiveness, intervention description (TIDieR) and risk of bias (EPOC). Narrative synthesis was performed due to study population, intervention and outcome heterogeneity.

RESULTS

Of 5614 citations, 13 were included. Five were RCTs, and eight non-randomised comparative studies. Participants had asthma (n = 2), HIV (n = 6), inflammatory bowel disease (IBD; n = 2), diabetes (n = 2) and risk of pre-eclampsia (n = 1). Interventions included education +/- counselling, financial incentives, text messaging, action plans, structured discussion and psychosocial support. One RCT found an effect  of the tested intervention on self-reported antiretroviral adherence but not objective adherence. Clinical outcomes were not evaluated. Seven non-randomised comparative studies found an association between the tested intervention and at least one outcome of interest: four found an association between receiving the intervention and both improved clinical or perinatal outcomes and adherence in women with IBD, gestational diabetes mellitus (GDM), and asthma. One study in women with IBD reported an association between receiving the intervention and maternal outcomes but not for self-reported adherence. Two studies measured only adherence outcomes and reported an association between receiving the intervention and self-reported and/or objective adherence in women with HIV and risk of pre-eclampsia. All studies had high or unclear risk of bias. Intervention reporting was adequate for replication in two studies according to the TIDieR checklist.

CONCLUSIONS

There is a need for high-quality RCTs reporting replicable interventions to evaluate medication adherence interventions in pregnant women and those planning pregnancy. These should assess both clinical and adherence outcomes.

Extending Maternal Care After Pregnancy: An Initiative to Address Health Care Disparities and Enhance Access to Care After Delivery

PROBLEM DEFINITION

A substantial proportion of maternal morbidity and mortality occurs after birth. However, little is known about the optimal design of programs to improve outcomes and decrease disparities during this period.

CONTEXT

Parkland Health is a tax-supported health system in Dallas that delivers more than 11,000 patients annually. A community needs assessment identified substantial health disparities in this community. The proportion of women in this region with diabetes mellitus (DM) and chronic hypertension (CHTN) during pregnancy is higher than surrounding regions, but access to care in the area is difficult because of the limited availability of ambulatory care.

INITIAL APPROACH

The authors created extending Maternal Care After Pregnancy (eMCAP), a community-based program, to address health care disparities and enhance access to care for the 12 months after birth. The team also evaluated the ability of Z codes (ICD-10 codes for social determinants of health) to identify patients with health-related social needs.

KEY INSIGHTS AND SURPRISES

The eMCAP program demonstrated improvement in attendance and quality of postpartum care for women living in underserved areas with CHTN and DM. For both CHTN and DM, eMCAP patients were matched 1:2 to controls outside of the eMCAP target region with similar comorbidities for maternal age ± 4 years, Black race, and delivery date ± 45 days. Compared to matched controls who were provided standard referrals, follow-up postpartum attendance for eMCAP women with CHTN was significantly better at 2 weeks and 1, 3, 6, 9, and 12 months (all p < 0.001). Similarly, eMCAP women with DM had significantly better follow-up at 2 weeks (p = 0.04), 1 month (p = 0.002), and 3 months (p = 0.049), resulting in HbA1c values for DM being significantly lower (p < 0.05) throughout the postpartum period. Despite the health system leading in reporting of Z codes, nearly 99% of applicable Z codes were not recorded, underscoring a public health opportunity. Through the eMCAP program, this initiative has demonstrated improved clinical performance for health care outcomes relevant to postpartum patients that can be deployed elsewhere to improve maternal health in underserved communities.

Understanding social needs in pregnancy: Prospective validation of a digital short-form screening tool and patient survey

BACKGROUND

Social determinants of health significantly affect health outcomes, yet are infrequently addressed in prenatal care.

OBJECTIVE

This study aimed to improve the efficiency and experience of addressing social needs in pregnancy through: (1) testing a digital short-form screening tool; and (2) characterizing pregnant people's preferences for social needs screening and management.

STUDY DESIGN

We developed a digital short-form social determinants of health screening tool from PRAPARE (Protocol for Responding to and Assessing Patients' Assets, Risks, and Experiences), and a survey to query patients' preferences for addressing social needs. Instruments were administered online to peripartum participants, with equal representation of patients with public and private insurance. We calculated the sensitivity and specificity of the short-form tool vs PRAPARE. Quantitative responses were characterized using descriptive statistics. Free-text responses were analyzed with matrix and thematic coding. Survey data were analyzed by subgroups of historically marginalized populations.

RESULTS

A total of 215 people completed the survey. Participants were predominantly White (167; 77.7%) and multiparous (145; 67.4%). Unmet social needs were prevalent with both the short-form tool (77.7%) and PRAPARE (96.7%). The sensitivity (79.3%) and specificity (71.4%) of the short-form screener were high for detecting any social need. Most participants believed that it was important for their pregnancy care team to know their social needs (material: 173, 80.5%; support: 200, 93.0%), and over half felt comfortable sharing their needs through in-person or digital modalities if assistance was or was not available (material: 117, 54.4%; support: 122, 56.7%). Free-text themes reflected considerations for integrating social needs in routine prenatal care. Acceptability of addressing social needs in pregnancy was high among all groups.

CONCLUSION

A digital short-form social determinants of health screening tool performs well when compared with the gold standard. Pregnant people accept social needs as a part of routine pregnancy care. Future work is needed to operationalize efficient, effective, patient-centered approaches to addressing social needs in pregnancy.

Risk for adverse maternal outcomes among women with chronic hypertension

OBJECTIVE

To determine whether longitudinal health data accounts for end-organ injury or death in the setting of chronic hypertension.

DESIGN

Cohort of 64 799 deliveries to 61 854 women.

SETTING

US claims data for the preiod 2008-2019.

POPULATION

Women with a delivery hospitalisation and chronic hypertension.

METHODS

Risk for a composite of acute end-organ injury or death during the delivery hospitalisation and 30 days postpartum was analysed. Adjusted logistic regression models were derived with discrimination for each model estimated by the C-statistic. Poisson regression was used to estimate adjusted risk ratios. Starting with models using data from pregnancy, further adjustment was performed accounting for healthcare use in the year prior to pregnancy, including hospitalisations, emergency department encounters, prescription medications and pre-pregnancy diagnoses.

MAIN OUTCOME MEASURES

Acute end-organ injury or death.

RESULTS

The composite outcome occurred among 5.7% of 64 799 deliveries. For patients with commercial insurance, filling non-hypertensive medications from ≥11 different classes, compared with none (adjusted risk ratio, aRR 4.07, 95% CI 2.86-5.79), three or more hospitalisations before pregnancy, compared with none (aRR 4.75, 95% CI 3.46-6.52), and chronic kidney disease diagnosed in the year before pregnancy (aRR 2.35, 95% CI 1.88, 2.94) were associated with increased risk. For pregnancies covered by commercial insurance, the C-statistic increased from 0.615 (95% CI 0.599-0.630) in the model with pregnancy data only to 0.796 (95% CI 0.783-0.808) for the model additionally including healthcare use in the year before pregnancy. Findings with Medicaid were similar.

CONCLUSIONS

Prepregnancy care use predicted adverse maternal outcomes. These data may be important in risk stratification.

The association between severe maternal morbidity and mortality and race/ethnicity with community type in Maryland

BACKGROUND

Severe maternal morbidity and mortality are increasing in the United States with continued healthcare disparities among Non-Hispanic Black women. However, there is sparse data on the disparities of severe maternal morbidity and mortality by race/ethnicity as it relates to community type.

OBJECTIVE

To determine whether residing in rural communities increases the racial/ethnic disparities in severe maternal morbidity and mortality.

DESIGN

This study is a cross-sectional analysis of women admitted for delivery from 2015 to 2020. A total of 204,140 adults who self-identified as women, were admitted for delivery, who resided in Maryland, and were between the ages 15 and 54 were included in our analysis. Community type was defined as either rural or urban.

METHODS

A multivariable logistic regression, which included an interaction term between race/ethnicity and community type, was used to assess the effect of community type on the relationship between race/ethnicity and severe maternal morbidity and mortality. Data were obtained from the Maryland Health Service Cost Review Commission database. The primary outcome was a composite, binary variable of severe maternal morbidity and mortality. Exposures of interest were residence in either rural or urban counties in Maryland and race/ethnicity.

RESULTS

Our study found that after adjusting for confounders, odds of severe maternal morbidity and mortality were 65% higher in Non-Hispanic Black women (odds ratio 1.65, 95% confidence interval: 1.46-1.88, p < 0.001) and 54% higher in Non-Hispanic Asian women (odds ratio 1.54, 95% confidence interval: 1.24-1.90, p < 0.001) compared to Non-Hispanic White women. The interaction term used to determine whether community type modified the relationship between race/ethnicity and severe maternal morbidity and mortality was not statistically significant for any race/ethnicity (Non-Hispanic Black women, p = 0.60; Non-Hispanic Asian women, p = 0.91; Hispanic women, p = 0.15; Other/Unknown race/ethnicity, p = 0.54).

CONCLUSION

Although our study confirmed the known disparities in maternal outcomes by race/ethnicity, we found that residing in rural communities did not increase racial/ethnic disparities.

Breastfeeding following bariatric surgery among obese women with and without diabetes mellitus

BACKGROUND

Information on exclusive breastfeeding (BF) and BF initiation following bariatric surgery (BS) among obese women with diabetes mellitus (DM) and without DM (non-DM) is limited.

METHODS

Retrospective cohort study. Obesity was defined by BMI (kg/m2) as grade 1 (30-34.9), grade 2 (35-39.9) or grade 3 (≥40). The 65 women in the DM group (40 women with gestational, 19 with Type 2 and 6 with Type 1) was similar to 84 with non-DM in BS type: Roux-en-Y (51 vs 55%), sleeve gastrectomy (32 vs 35%), laparoscopic gastric banding (17 vs 7%) and gastro-duodenal anastomosis (0 vs 4%).

RESULTS

Women with DM were older (35 vs 33y), of advanced age (54 vs 27%), with higher prevalence of grade 3 obesity (66 vs 46%), chronic hypertension (31 vs 10%), delivery of late-preterm infants (23 vs 10%) and neonatal hypoglycemia (25 vs 12%). Although infant feeding intention was similar: BF (66 vs 79%), partial BF (9 vs 7%) or formula (25 vs 14%), at discharge women with DM had lower exclusive BF (29 vs 41%) and BF initiation rates (68 vs 76%) than those with non-DM. Women with grade 3 obesity (52% were DM) differed from those with grades 1-2 (34% were DM) in exclusive BF (27 vs 52%), and BF initiation rates (66 vs 86%).

CONCLUSION

After BS, women with DM, especially those with grade 3 obesity, had higher rates of chronic hypertension and preeclampsia and lower rates of exclusive BF and BF initiation than those who had DM but had less severe obesity.

Major congenital malformations in offspring of women with chronic diseases-impact of the disease or the treatment?

In a narrative review, we summarized previous findings on the risk of major congenital malformations in offspring of women with chronic hypertension, hypothyroidism, or depression compared with the background population, and evaluated whether exposure to medical treatment in the first trimester affected this risk. In a literature search in the PubMed database, cohort studies were included if they were published from 2010 to 2022 and contained data on major congenital malformations from ≥500 offspring of women with chronic hypertension, hypothyroidism, or depression during the first trimester of pregnancy, and data on both untreated and treated women. Data were compared with the background population of women without these diseases. In total, 7 cohort studies were identified. In comparison with the background population, 2 studies including 54,996 offspring of women with chronic hypertension showed an adjusted odds ratio of 1.20 to 1.30 for major congenital malformations in the offspring, regardless of antihypertensive treatment. One study including 16,364 offspring of women with hypothyroidism showed an adjusted odds ratio of 1.14 (1.06-1.22) for major congenital malformations in the offspring, regardless of thyroid substitution. Four studies including 48,913 offspring of women with depression showed adjusted odds ratios of 1.07 to 1.27 (0.91-1.78) for major congenital malformations in the offspring of untreated women. Three of these 4 studies showed similar prevalence of malformations in women treated for depression. The findings of this narrative review suggest that chronic hypertension and hypothyroidism, rather than exposure to their medical treatments in the first trimester, were associated with increased risk of major congenital malformations, whereas depression was generally not associated with major congenital malformations.

Sociodemographic differences in quality of treatment to Medicaid enrollees receiving buprenorphine

Background: Buprenorphine is a key medication to treat opioid use disorder, but little is known about how treatment quality varies across sociodemographic groups. Objective: We examined measures of treatment quality and explored variation by sociodemographic factors. Methods: We used Medicaid MAX data from 50 states from 2006 to 2014 to identify buprenorphine treatment episodes (N = 317,494). We used multivariable logistic regression to examine the quality of buprenorphine treatment along four dimensions: (1) sufficient duration, (2) effective dosage, and concurrent prescribing of (3) opioid analgesics and (4) benzodiazepines. We explored how quality varied by race/ethnicity, age, sex, and urbanicity. Results: In adjusted models, compared to non-Hispanic White individuals, non-Hispanic Black and Hispanic individuals had lower odds of receiving effective dosage (aORs = 0.79 and 0.89, respectively) and sufficient duration (aORs = 0.64 and 0.71, respectively), and lower odds of concurrent prescribing of opioid analgesics (aORs = 0.86 and 0.85, respectively) and benzodiazepines (aORs = 0.51 and 0.59, respectively). Older individuals had higher odds of sufficient duration (aORs from 1.21-1.33), but also had higher odds of concurrent opioid analgesics prescribing (aORs from 1.29-1.56) and benzodiazepines (aORs from 1.44-1.99). Females had higher odds of sufficient duration (aOR = 1.12), but lower odds of effective dosage (aOR = 0.77) and higher odds of concurrent prescribing of opioid analgesics (aOR = 1.25) and benzodiazepines (aOR = 1.16). Compared to individuals living in metropolitan areas, individuals living in non-metropolitan areas had higher odds of sufficient duration (aORs = 1.11 and 1.24) and effective dosage (aORs = 1.06 and 1.33), and lower odds of concurrent prescribing (aORs from 0.81-0.98). Conclusions: Black and Hispanic individuals were less likely to receive effective buprenorphine dosage and sufficient duration. Quality results were mixed for older and female individuals; although these individuals were more likely to receive treatment of sufficient duration, they were also more likely to be concurrently prescribed potentially contraindicated medications, and females were less likely to receive effective dosage. Findings raise concerns about adequacy of care for minority and other at-risk populations.

Delayed entry into prenatal care among women with pre-pregnancy health conditions, National Birth Defects Prevention Study, 1997-2011

First trimester entry into prenatal care is recommended for all women, and especially women with pre-pregnancy conditions. Our objective was to determine whether women with pre-pregnancy conditions were at lower risk of entry after the first trimester (delayed entry) into prenatal care than women without a pre-pregnancy health condition. We used data from 10,890 participants in the National Birth Defects Prevention Study who delivered liveborn infants without birth defects. Women reported pre-pregnancy conditions and timing of entry into prenatal care during a computer-assisted telephone interview. Multivariable logistic regression analyses were conducted to evaluate whether having a pre-pregnancy condition was associated with delayed entry into prenatal care compared to women without pre-pregnancy conditions. Approximately 13% of women reported delayed entry into prenatal care, and 18% of women reported a pre-pregnancy condition. Delayed entry into prenatal care was not associated with pre-pregnancy cardiometabolic or neurologic conditions. Women with thyroid conditions were less likely to report delayed entry into prenatal care (prevalence odds ratio (OR), 95% confidence interval (CI): 0.55 [0.32, 0.94]), but women with hematologic and respiratory conditions were more likely to report delayed entry into prenatal care (OR: 1.95 [1.00, 3.82] and 1.27 [0.95, 1.72], respectively), compared to those without any chronic conditions. Future research investigating the success of early prenatal care among women with thyroid conditions could identify ways to reduce delayed prenatal care among women with other pre-pregnancy conditions.

Non-communicable diseases and maternal health: a scoping review

Background

Non-communicable diseases [NCDs] are leading causes of ill health among women of reproductive age and an increasingly important cause of maternal morbidity and mortality worldwide. Reliable data on NCDs is necessary for accurate measurement and response. However, inconsistent definitions of NCDs make reliable data collection challenging. We aimed to map the current global literature to understand how NCDs are defined, operationalized and discussed during pregnancy, childbirth and the postnatal period. 

Methods

For this scoping review, we conducted a comprehensive global literature search for NCDs and maternal health covering the years 2000 to 2020 in eleven electronic databases, five regional WHO databases and an exhaustive grey literature search without language restrictions. We used a charting approach to synthesize and interpret the data. 

Results

Only seven of the 172 included sources defined NCDs. NCDs are often defined as chronic but with varying temporality. There is a broad spectrum of conditions that is included under NCDs including pregnancy-specific conditions and infectious diseases. The most commonly included conditions are hypertension, diabetes, epilepsy, asthma, mental health conditions and malignancy. Most publications are from academic institutions in high-income countries [HICs] and focus on the pre-conception period and pregnancy. Publications from HICs discuss NCDs in the context of pre-conception care, medications, contraception, health disparities and quality of care. In contrast, publications focused on low- and middle-income countries discuss NCDs in the context of NCD prevention. They take a life cycle approach and advocate for integration of NCD and maternal health services.

Conclusion

Standardising the definition and improving the articulation of care for NCDs in the maternal health setting would help to improve data collection and facilitate monitoring. It would inform the development of improved care for NCDs at the intersection with maternal health as well as through a woman's life course. Such an approach could lead to significant policy and programmatic changes with the potential corresponding impact on resource allocation.

Experiences With Prenatal Care Delivery Reported by Black Patients With Low Income and by Health Care Workers in the US: A Qualitative Study

IMPORTANCE

Black pregnant people with low income face inequities in health care access and outcomes in the US, yet their voices have been largely absent from redesigning prenatal care.

OBJECTIVE

To examine patients' and health care workers' experiences with prenatal care delivery in a largely low-income Black population to inform care innovations to improve care coordination, access, quality, and outcomes.

DESIGN, SETTING, AND PARTICIPANTS

For this qualitative study, human-centered design-informed interviews were conducted at prenatal care clinics with 19 low-income Black patients who were currently pregnant or up to 1 year post partum and 19 health care workers (eg, physicians, nurses, and community health workers) in Detroit, Michigan, between October 14, 2019, and February 7, 2020. Questions focused on 2 human-centered design phases: observation (understanding problems from the end user's perspective) and ideation (generating novel potential solutions). Questions targeted participants' experiences with the 3 goals of prenatal care: medical care, anticipatory guidance, and social support. An eclectic analytic strategy, including inductive thematic analysis and matrix coding, was used to identify promising strategies for prenatal care redesign.

MAIN OUTCOMES AND MEASURES

Preferences for prenatal care redesign.

RESULTS

Nineteen Black patients (mean [SD] age, 28.4 [5.9] years; 19 [100%] female; and 17 [89.5%] with public insurance) and 17 of 19 health care workers (mean [SD] age, 47.9 [15.7] years; 15 female [88.2%]; and 13 [76.5%] Black) completed the surveys. A range of health care workers were included (eg, physicians, doulas, and social workers). Although all affirmed the 3 prenatal care goals, participants reported failures and potential solutions for each area of prenatal care delivery. Themes also emerged in 2 cross-cutting areas: practitioners and care infrastructure. Participants reported that, ideally, care structure would enable strong ongoing relationships between patients and practitioners. Practitioners would coordinate all prenatal services, not just medical care. Finally, care would be tailored to individual patients by using care navigators, flexible models, and colocation of services to reduce barriers.

CONCLUSIONS AND RELEVANCE

In this qualitative study of low-income, Black pregnant people in Detroit, Michigan, and the health care workers who care for them, prenatal care delivery failed to meet many patients' needs. Participants reported that an ideal care delivery model would include comprehensive, integrated services across the health care system, expanding beyond medical care to also include patients' social needs and preferences.

Severe Maternal Morbidity and Mortality Risk at the Intersection of Rurality, Race and Ethnicity, and Medicaid

OBJECTIVE

We examined differences in rates of severe maternal morbidity and mortality (SMMM) among Medicaid-funded compared with privately insured hospital births through specific additive and intersectional risk by rural or urban geography, race and ethnicity, and clinical factors.

METHODS

We used maternal discharge records from childbirth hospitalizations in the Health care Cost and Utilization Project's National Inpatient Sample from 2007 to 2015. We calculated predicted probabilities using weighted multivariable logistic regressions to estimate adjusted rates of SMMM, examining differences in rates by payer, rurality, race and ethnicity, and clinical factors. To assess the presence and extent of additive risk by payer, with other risk factors, on rates of SMMM, we estimated the proportion of the combined effect that was due to the interaction.

RESULTS

In this analysis of 6,357,796 hospitalizations for childbirth, 2,932,234 were Medicaid funded and 3,425,562 were privately insured. Controlling for sociodemographic and clinical factors, the highest rate of SMMM (224.9 per 10,000 births) occurred among rural Indigenous Medicaid-funded births. Medicaid-funded births among Black rural and urban residents, and among Hispanic urban residents, also experienced elevated rates and significant additive interaction. Thirty-two percent (Bonferroni-adjusted 95% confidence interval, 19%-45%) of SMMM cases among patients with chronic heart disease were due to payer interaction, and 19% (Bonferroni-adjusted 95% confidence interval, 17%-22%) among those with cesarean birth were due to the interaction.

CONCLUSIONS

Heightened rates of SMMM among Medicaid-funded births indicate an opportunity for tailored state and federal policy responses to address the particular maternal health challenges faced by Medicaid beneficiaries, including Black, Indigenous, and rural residents.

Association between pre-pregnancy multimorbidity and adverse maternal outcomes: A systematic review

Objective

We reviewed the literature on the association between pre-pregnancy multimorbidity (co-occurrence of two or more chronic conditions) and adverse maternal outcomes in pregnancy and postpartum.

Data sources

Medline, EMBASE, and CINAHL were searched from inception to September, 2021.

Study selection

Observational studies were eligible if they reported on the association between ≥ 2 co-occurring chronic conditions diagnosed before conception and any adverse maternal outcome in pregnancy or within 365 days of childbirth, had a comparison group, were peer-reviewed, and were written in English.

Data extraction and synthesis

Two reviewers used standardized instruments to extract data and rate study quality and the certainty of evidence. A narrative synthesis was performed.

Results

Of 6,381 studies retrieved, seven met our criteria. There were two prospective cohort studies, two retrospective cohort studies, and 3 cross-sectional studies, conducted in the United States (n=6) and Canada (n=1), and ranging in size from n=3,110 to n=57,326,681. Studies showed a dose-response relation between the number of co-occurring chronic conditions and risk of adverse maternal outcomes, including severe maternal morbidity or mortality, hypertensive disorders of pregnancy, and acute health care use in the perinatal period. Study quality was rated as strong (n=1), moderate (n=4), or weak (n=2), and the certainty of evidence was very low to moderate.

Conclusion

Given the increasing prevalence of chronic disease risk factors such as advanced maternal age and obesity, more research is needed to understand the impact of pre-pregnancy multimorbidity on maternal health so that appropriate preconception and perinatal supports can be developed.

Racial/Ethnic Differences in Prenatal Supplement and Medication Use in Low-Risk Pregnant Women

OBJECTIVE

This study aimed to describe the overall quantity and type of supplements and medications used during pregnancy in a low-risk cohort and to examine any racial/ethnic differences in intake.

STUDY DESIGN

We used data from 2,164 racially/ethnically diverse, nonobese, and low-risk pregnant women participating without pre-pregnancy chronic conditions in a prospective cohort study at 12 sites across the United States. Medication data were self-reported as free text in enrollment, follow-up visit questionnaires, and abstracted from medical records at delivery. Supplements and medications data were mapped to their active ingredients and categorized into corresponding classes using the Slone Drug Dictionary. The total number and classes of supplements and medications consumed during pregnancy were calculated. Modified Poisson regression models were used to estimate the racial/ethnic differences in supplements and medications intake. All models were adjusted for maternal sociodemographic factors and study site.

RESULTS

98% of women took at least one supplement during pregnancy, with prenatal vitamins/multivitamins being most common. While only 31% reported taking no medications during pregnancy, 23% took one, 18% took two, and 28% took three or more. The percentage of women taking at least one medication during pregnancy was highest among non-Hispanic white women and lowest among Asians (84 vs. 55%, p < 0.001). All racial/ethnic groups reported taking the same top four medication classes including central nervous system agents, gastrointestinal drugs, anti-infective agents, and antihistamines. Compared with non-Hispanic white women, Hispanic (adjusted relative risk [aRR]: 0.84, 95% confidence interval [CI]: 0.71-0.98), and Asian women (aRR: 0.83, 95% CI: 0.70-0.98) were less likely to take central nervous system agents, as well as gastrointestinal drugs (Hispanics aRR: 0.79, 95% CI: 0.66-0.94; Asians aRR = 0.75, 95% CI: 0.63-0.90), and antihistamines (Hispanics aRR: 0.65, 95% CI: 0.47-0.92).

CONCLUSION

Supplement intake was nearly universal. Medication use was also common among this low-risk pregnancy cohort and differed by race/ethnicity.

GOV IDENTIFIER

NCT00912132.

KEY POINTS

· In women without chronic conditions, medication use is common.. · Racial/ethnic differences exist in prenatal medications use.. · Almost all women use supplements during pregnancy..

Mortality Rates Among U.S. Women of Reproductive Age, 1999-2019

INTRODUCTION

High and increasing levels of pregnancy-related mortality and morbidity in the U.S. indicate that the underlying health status of reproductive-aged women may be far from optimal, yet few studies have examined mortality trends and disparities exclusively among this population.

METHODS

All-cause and cause-specific mortality data for 1999-2019 were obtained from the Centers for Disease Control and Prevention WONDER Underlying Cause of Death database. Levels and trends in mortality between 1999 and 2019 for women aged 15-44 years stratified by age, race/ethnicity, and state were examined. Given the urgent need to address pregnancy-related health disparities, the correlation between all-cause and pregnancy-related mortality rates across states for the years 2015-2019 was also examined.

RESULTS

Age-adjusted, all-cause mortality rates among women aged 15-44 years improved between 2003 and 2011 but worsened between 2011 and 2019. The recent increase in mortality among this age group was not driven solely by increases in external causes of death. Patterns differed by age, race/ethnicity, and geography, with non-Hispanic American Indian and Alaskan Native women having 2.3 and non-Hispanic Black women having 1.4 times the risk of all-cause mortality in 2019 compared with that of non-Hispanic White women. Age-adjusted all-cause mortality rates and pregnancy-related mortality rates were strongly correlated at the state level (r=0.75).

CONCLUSIONS

Increasing mortality among reproductive-aged women has substantial implications for maternal, women's, and children's health. Given the high correlation between pregnancy-related mortality and all-cause mortality at the state level, addressing the structural factors that shape mortality risks may have the greatest likelihood of improving women's health outcomes across the life course.

Insurance Churn and Postpartum Health among Texas Women with Births Covered by Medicaid/CHIP

INTRODUCTION

Insurance churn (changes in coverage) after childbirth is common in the United States, particularly in states that have not expanded Medicaid coverage. Although insurance churn may have lasting consequences for health care access, most research has focused on the initial weeks after a birth.

METHODS

We analyzed data from a cohort study of postpartum Texans with pregnancies covered by public insurance (n = 1,489). Women were recruited shortly after childbirth from eight hospitals in six cities, completing a baseline survey in the hospital and follow-up surveys at 3, 6, and 12 months. We assessed insurance trajectories, health care use, and health indicators over the 12 months after childbirth. We also conducted a content analysis of women's descriptions of postpartum health concerns.

RESULTS

A majority of participants (64%) became uninsured within 3 months of the birth and remained uninsured for the duration of the study; 88% were uninsured at some point in the year after the birth. At 3 months postpartum, 17% rated their health as fair or poor, and 13% reported a negative change in their health after the 3-month survey. Women's open-ended responses described financial hardships and other difficulties accessing care for postpartum health issues, which included acute and ongoing conditions, undiagnosed concerns, pregnancy and reproductive health, mental health, and weight/lifestyle concerns.

CONCLUSIONS

Insurance churn was common among postpartum women with births covered by Medicaid/CHIP and prevented many women from receiving health care. To improve postpartum health and reduce maternal mortality and morbidity, states should work to stabilize insurance coverage for women with low incomes.

Maternal health expert feedback on the attributes of a predictive analytics tool to improve pregnancy-related cardiovascular and mental health outcomes in the United States

Identify pregnancy-related challenges and opportunities to improve maternal health care in the United States and understand the potential role of predictive analytics tool(s) in bridging the existing gaps, specifically, in CVD (cardiovascular disease) and depression. Experts in maternal health care, research, patient advocacy, CVD, psychiatry, and technology were interviewed during February and March of 2020. Additionally, published literature was reviewed to assess existing data, insights, and best practices that might help develop effective predictive analytics tool(s). The majority (78%) of the 18 experts interviewed were women. The feedback revealed several insights, including multiple barriers to diagnosis and treatment of pregnancy-related CVD and depression. In experts' collective opinion, predictive analytics could play an important role in maternal health care and in limiting pregnancy-related CVD and depression, but it must be grounded in quality data and integrate with existing health management systems. A holistic approach to maternal health that factors in racial-ethnic, regional, and socioeconomic disparities is needed that starts with preconception counseling and continues through 1 year postpartum. Predictive analytics tool(s) that are based on diverse and high-quality data could bridge some of the existing gaps in maternal health care and potentially help limit pregnancy-related CVD and depression.

Usage of Digital Health Tools and Perception of mHealth Intervention for Physical Activity and Sleep in Black Women

Black women of reproductive age are disproportionately affected by chronic health conditions and related disease risk factors such as physical inactivity and obesity. Health promotion studies need to focus on this population since optimizing preconception health will lead to improvement of both birth outcomes and the woman’s long-term health. mHealth interventions that utilize wearable sensors to provide personalized and timely feedback can be used to promote physical activity (PA). This study aimed to examine Black women’s wearable sensor usage and their perceptions about future mHealth interventions that target PA and sleep. Our analysis included 497 Black women (aged 18–47 years) who completed a cross-sectional online survey. Ninety-two percent of participants did not meet the recommended level of PA, and 32.3% reported poor sleep quality. More participants indicated interest in a remote PA program (77%) than an in-person one (73%). More than half of participants indicated interest in receiving personalized feedback messages based on wearable trackers about PA (58.1%) and sleep (63.5%). This perceived acceptability of remote intervention and wearable-based feedback messages did not differ by socioeconomic status. Remotely delivered mHealth interventions that utilize wearables can be a viable behavioral change strategy to promote PA and sleep quality in Black women.

Exclusive breastfeeding among women with type 1 and type 2 diabetes mellitus

Objective

To compare exclusive breastfeeding (BF) and BF initiation among 185 women with Type 1 and 212 women with Type 2 pregestational diabetes who intended exclusive or partial BF and delivered at ≥34 weeks of gestation.

Methods

Retrospective cohort study. At discharge, exclusive BF is direct BF or BF complemented with expressed breast milk. BF initiation is defined by exclusive or partial BF.

Results

Type 1 and Type 2 groups were similar in prior BF experience (69 vs 67%) but were different in intention to BF exclusively (92 vs 78%) and partially (8 vs 22%). Women in the Type 1 group were younger (median age 30 vs 33y), likely to be primiparous (47 vs 25%), have a lower median BMI (32 vs 36 kg/m²) and deliver by primary cesarean (37 vs 26%). Infants born to Type 1 women were more likely to be admitted to the NICU (44 vs 18%) and to have hypoglycemia (59 vs 41%). At discharge, exclusive BF among Type 1 was higher (34 vs 23%), partial BF was similar (47 vs 46%) while FF (formula feeding) was lower (19 vs 31%) than in the Type 2 group. BF initiation occurred in 81% of Type 1 and 69% of Type 2 women.

Conclusion

Intention to BF exclusively was higher in Type 1 women compared to Type 2. At discharge, exclusive BF and BF initiation were lower and FF higher in the Type 2 group highlighting the need for different strategies if lactation in this special population is to be improved.
