Postpartum Visit Attendance in the United States: A Systematic Review

Strategies to improve postpartum engagement in healthcare after high-risk conditions diagnosed in pregnancy: a narrative review

Transition from antepartum to postpartum care is important, but often fragmented, and attendance at postpartum visits can be poor. Access to care is especially important for individuals diagnosed antepartum with conditions associated with longer-term implications, including gestational diabetes (GDM) and hypertensive disorders in pregnancy (HDP). Strategies to link and strengthen this transition are essential to support people to attend recommended appointments and testing. This narrative review evaluates what is known about postpartum transition of care after higher-risk antepartum conditions, discusses barriers and facilitators to uptake of recommended testing, and outlines strategies trialled to increase both postpartum attendance and testing. Barriers to attendance frequently overlap with general barriers to accessing healthcare. Specific postpartum challenges include difficulties with transport, coordinating breastfeeding and childcare access. Systemic challenges include inadequate communication to women around implications of health conditions diagnosed in pregnancy, and the importance of postpartum follow up. Uptake of recommended testing after a diagnosis of GDM and HDP is variable but generally suboptimal. Strategies which demonstrate promise include the use of patient navigators, focused education and specialised clinics. Reminder systems have had variable impact. Telehealth and technology are under-utilised in this field but offer promising options particularly with the expansion of virtual healthcare into routine maternity care. Strategies to improve both attendance rates and uptake of testing must be designed to address disparities in healthcare access and tailored to the needs of the community. This review provides a starting point to develop such strategies from the community level to the population level.

Severe maternal morbidity from pregnancy through 1 year postpartum

BACKGROUND

Few recent studies have examined the rate of severe maternal morbidity occurring during the antenatal and/or postpartum period to 42 days after delivery. However, little is known about the rate of severe maternal morbidity occurring beyond 42 days after delivery.

OBJECTIVE

This study aimed to examine the distribution of severe maternal morbidity and its indicators during antenatal, delivery, and postpartum hospitalizations to 365 days after delivery and to estimate the increase in severe maternal morbidity rate and its indicators after accounting for antenatal and postpartum severe maternal morbidity to 365 days after delivery.

STUDY DESIGN

This was a retrospective cohort study using birth and fetal death certificate data linked to hospital discharge records from Michigan, Oregon, and South Carolina from 2008 to 2020. This study examined the distribution of severe maternal morbidity, nontransfusion severe maternal morbidity, and severe maternal morbidity indicators during antenatal, delivery, and postpartum hospitalizations to 365 days after delivery. Subsequently, this study examined "severe maternal morbidity cases added," which represent cases among unique individuals that are included by considering the antenatal and postpartum periods but that would be missed if only the delivery hospitalization cases were included.

RESULTS

A total of 64,661 (2.5%) individuals experienced severe maternal morbidity, whereas 37,112 (1.4%) individuals experienced nontransfusion severe maternal morbidity during antenatal, delivery, and/or postpartum hospitalization. A total of 31% of severe maternal morbidity cases were added after accounting for severe maternal morbidity occurring during the antenatal or postpartum hospitalization to 365 days after delivery, whereas 49% of nontransfusion severe maternal morbidity cases were added after accounting for nontransfusion severe maternal morbidity occurring during the antenatal or postpartum periods. Severe maternal morbidity occurring between 43 and 365 days after delivery contributed to 12% of all severe maternal morbidity cases, whereas nontransfusion severe maternal morbidity occurring between 43 and 365 days after delivery contributed to 19% of all nontransfusion severe maternal morbidity cases.

CONCLUSION

Our study showed that a total of 31% of severe maternal morbidity and 49% of nontransfusion severe maternal morbidity cases were added after accounting for severe maternal morbidity occurring during the antenatal or postpartum hospitalization to 365 days after delivery. Our findings highlight the importance of expanding the severe maternal morbidity definition beyond the delivery hospitalization to better capture the full period of increased risk, identify contributing factors, and design strategies to mitigate this risk. Only then can we improve outcomes for mothers and subsequently the quality of life of their infants.

Mapping the Postpartum Experience Through Obstetric Patient Navigation for Low-Income Individuals

Background: Although the postpartum period is an opportunity to address long-term health, fragmented care systems, inadequate attention to social needs, and a lack of structured transition to primary care threaten patient wellbeing, particularly for low-income individuals. Postpartum patient navigation is an emerging innovation to address these disparities. Methods: This mixed-methods analysis uses data from the first year of an ongoing randomized controlled trial to understand the needs of low-income postpartum individuals through 1 year of patient navigation. We designed standardized logs for navigators to record their services, tracking mode, content, intensity, and target of interactions. Navigators also completed semistructured interviews every 3 months regarding relationships with patients and care teams, care system gaps, and navigation process. Log data were categorized, quantified, and mapped temporally through 1 year postpartum. Qualitative data were analyzed using the constant comparative method. Results: Log data from 50 participants who received navigation revealed the most frequent needs related to health care access (45.4%), health and wellness (18.2%), patient-navigator relationship building (14.8%), parenting (13.6%), and social determinants of health (8.0%). Navigation activities included supporting physical and mental recovery, accomplishing health goals, connecting patients to primary and specialty care, preparing for health system utilization beyond navigation, and referring individuals to community resources. Participant needs fluctuated, yielding a dynamic timeline of the first postpartum year. Conclusion: Postpartum needs evolved throughout the year, requiring support from various teams. Navigation beyond the typical postpartum care window may be useful in mitigating health system barriers, and tracking patient needs may be useful in optimizing postpartum care.

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.

Racial and ethnic disparities in severe maternal morbidity from pregnancy through 1-year postpartum

BACKGROUND

Previous studies examining racial and ethnic disparities in severe maternal morbidity (SMM) have mainly focused on intrapartum hospitalization. There is limited information regarding the racial and ethnic distribution of SMM occurring in the antepartum and postpartum periods, including SMM occurring beyond the traditional 6 weeks postpartum period.

OBJECTIVE

To examine the racial and ethnic distribution of SMM during antepartum, intrapartum, and postpartum hospitalizations through 1-year postpartum, overall and stratified by maternal sociodemographic factors, and to estimate the percent increase in SMM by race and ethnicity and maternal sociodemographic factors within each racial and ethnic group after accounting for both antepartum and postpartum SMM through 1-year postpartum rather than just SMM occurring during the intrapartum hospitalization.

STUDY DESIGN

We conducted a retrospective cohort study using birth and fetal death certificate data linked to hospital discharge records from Michigan, Oregon, and South Carolina from 2008-2020. We examined the distribution of non-transfusion SMM and total SMM per 10,000 cases during antepartum, intrapartum, and postpartum hospitalizations through 365 days postpartum by race and ethnicity and by maternal education and insurance type within each racial and ethnic group. We subsequently examined "SMM cases added" by race and ethnicity and by maternal education and insurance type within each racial and ethnic group. The "SMM cases added" represent cases among unique individuals that are identified by considering the antepartum and postpartum periods but that would be missed if only the intrapartum hospitalization cases were included.

RESULTS

Among 2,584,206 birthing individuals, a total of 37,112 (1.4%) individuals experienced non-transfusion SMM and 64,661 (2.5%) experienced any SMM during antepartum, intrapartum, and/or postpartum hospitalization. Black individuals had the highest rate of antepartum, intrapartum, and postpartum non-transfusion and total SMM followed by American Indian individuals. Asian individuals had the lowest rate of non-transfusion and total SMM during antepartum and postpartum hospitalizations while White individuals had the lowest rate of non-transfusion and total SMM during the intrapartum hospitalization. Black individuals were 1.9 times more likely to experience non-transfusion SMM during the intrapartum hospitalization than White individuals, which increased to 2.8 times during the antepartum period and to 2.5 times during the postpartum period. Asian and Hispanic individuals were less likely to experience SMM in the postpartum period than White individuals. Including antepartum and postpartum hospitalizations resulted in disproportionately more cases among Black and American Indian individuals than among White, Hispanic, and Asian individuals. The additional cases were also more likely to occur among individuals with lower educational levels and individuals on government insurance.

CONCLUSION

Racial disparities in SMM are underreported in estimates that focus on the intrapartum hospitalization. Additionally, individuals with low socio-economic status bear the greatest burden of SMM occurring during the antepartum and postpartum periods. Approaches that focus on mitigating SMM during the intrapartum period only do not address the full spectrum of health disparities.

Planning for the forgotten fourth trimester of pregnancy: A parallel group randomized control trial to test a postpartum planning intervention vs. standard prenatal care

BACKGROUND

Black and brown birthing people experience persistent disparities in adverse maternal health outcomes, partially due to inadequate perinatal care. The goal of this study is to design and evaluate a patient-centered intervention for obstetric patients with one or more cardiometabolic risk factors for severe maternal morbidity [gestational diabetes, diabetes mellitus, hypertensive disorders of pregnancy (chronic hypertension, preeclampsia, eclampsia, or gestational hypertension), or preconception obesity (BMI > 30)] to promote postpartum visit attendance.

METHODS

To address identified unmet needs for postpartum support and barriers to postpartum care, we developed 20 thematic postpartum planning modules, each with corresponding patient educational materials, community resources, care coordination protocols, and clinician support tools (decision aids, electronic medical record prompts and fields). During prenatal care encounters, a research coordinator delivers the educational content (in English or Spanish), facilitates the participant's planning and shared decision-making, provides the participant with resources, and documents decisions in the electronic medical record. We will randomize 320 eligible patients with a 1:1 ratio to the intervention or standard prenatal care and evaluate the impact on postpartum visit attendance at 4-12 weeks and secondary outcomes (postpartum mental health, perceived future maternal and cardiometabolic risk, contraceptive use, primary care use, readmission, and patient satisfaction with care).

DISCUSSION

Through engagement with patients and community stakeholders, we developed a guideline-based, locally tailored intervention to address drivers of engagement with postpartum care for high-risk obstetric patients. If demonstrated to be effective, the educational materials and electronic medical record based-tool can be adapted to other settings.

TRIAL REGISTRATION

CDC's New Hepatitis C Virus Testing Recommendations for Perinatally Exposed Infants and Children: A Step Towards Hepatitis C Elimination

New U.S. Centers for Disease Control and Prevention (CDC) guidelines for hepatitis C virus (HCV) testing of perinatally exposed infants and children released in 2023 recommend a nucleic acid test (NAT) for detection of HCV ribonucleic acid (i.e., NAT for HCV RNA) at 2-6 months of age to facilitate early identification and linkage to care for children with perinatally acquired HCV infection. Untreated hepatitis C can lead to cirrhosis, liver cancer, and premature death and is caused by HCV, a blood-borne virus transmitted most often among adults through injection drug use in the United States. Perinatal exposure from a birth parent with HCV infection is the most frequent mode of HCV transmission among infants and children. New HCV infections have been increasing since 2010, with the highest rates of infection among people aged 20-39 years, leading to an increasing prevalence of HCV infection during pregnancy. In 2020, the CDC recommended one-time HCV screening for all adults aged 18 years and older and for all pregnant persons during each pregnancy. Detecting HCV infection during pregnancy is key for the identification of pregnant persons, linkage to care for postpartum treatment, and identification of infants with perinatal exposure for HCV testing. It was previously recommended that children who were exposed to HCV during pregnancy receive an antibody to HCV (anti-HCV) test at 18 months of age; however, most children were lost to follow-up before testing occurred, leaving children with perinatal infection undiagnosed. The new strategy of testing perinatally exposed children at age 2-6 months was found to be cost-effective in increasing the identification of infants who might develop chronic hepatitis C. This report describes the current perinatal HCV testing recommendations and how they advance national hepatitis C elimination efforts by improving the health of pregnant and postpartum people and their children.

Implementation of In-Hospital Postpartum Glucose Tolerance Testing for People with Gestational Diabetes

OBJECTIVE

 We aimed to evaluate uptake of the glucose tolerance test performed during delivery hospitalization as part of routine clinical care.

STUDY DESIGN

 This is a retrospective cohort study of people with GDM at a tertiary center. We collected 9 months of postimplementation data after the in-hospital ("early") glucose tolerance test was adopted as a routine screening option. Adherence was compared between those who elected early glucose tolerance testing versus those who deferred testing to the standard postpartum period. Bivariable statistics including demographics, care team, and postpartum testing/visit attendance were compared between those who received early testing and those who did not using chi-square, Fisher's exact, and t-tests.

RESULTS

 A total of 681 patients with GDM delivered during the study period. Of those who had an early glucose tolerance test ordered (n = 408), 340 (83.3%) completed the test. Among those who did not complete an early glucose tolerance test (ordered and not completed or never ordered), only 104/341 (30.5%) completed any postpartum glucose testing in the first 12 months of postpartum. There were significant differences in characteristics in terms of race/ethnicity, insurance, type of gestational diabetes (A1GDM vs. A2GDM), diabetes medications, obstetric care provider, and delivery mode. Among those who completed early testing, 43.7% of participants had impaired glucose metabolism and 6.5% had values concerning for overt diabetes mellitus. Among those who deferred testing to the standard 6- to 12-week period, 24.0% had impaired glucose metabolism and none had overt diabetes. Those who completed an early glucose tolerance test had a lower rate of postpartum visit attendance compared with those who deferred (75.6 vs. 91.5%, p < 0.01).

CONCLUSION

 In this cohort, when the early glucose tolerance test is offered in clinical practice, adherence rates are higher than when the test is deferred until the postpartum visit.

KEY POINTS

· Adherence rates with the early glucose tolerance test (GTT) are higher than if the testing is deferred.. · Those who completed an early GTT had a lower rate of postpartum visit attendance compared with those who deferred.. · Offering an in-hospital postpartum GTT can help address low rates of glucose testing postpartum..

Association of Postpartum Mental Illness Diagnoses with Severe Maternal Morbidity

Background: This study aimed to determine whether birthing people who experience severe maternal morbidity (SMM) are more likely to be diagnosed with a postpartum mental illness. Materials and Methods: Using the Massachusetts All Payer Claims Database, this study used modified Poisson regression analysis to assess the association of SMM with mental illness diagnosis during the postpartum year, accounting for prenatal mental illness diagnoses and other patient characteristics. Results: There were 128,161 deliveries identified, with 55.0% covered by Medicaid. Of these, 3.1% experienced SMM during pregnancy and/or delivery hospitalization, and 20.1% had a mental illness diagnosis within 1 year postpartum. In adjusted regression analyses, individuals with SMM had a 10.6% increased risk of having any mental illness diagnosis compared to individuals without SMM, primarily due to an increased risk of a depression or post-traumatic stress disorder diagnosis among people with SMM than those without SMM. Conclusions: Individuals who experienced SMM had a higher risk of a mental illness diagnosis in the postpartum year. Given increases in SMM in the United States in recent decades, policies to mitigate mental health sequelae of SMM are urgently needed.

Disparities in Postpartum Care Visits: The Dynamics of Parental Leave Duration and Postpartum Care Attendance

OBJECTIVES

To understand differences in the relationship between parental leave duration and postpartum care across sociodemographic and income groups.

METHODS

We used data from six states participating in the Center for Disease Control and Prevention's yearly PRAMS study from 2016 to 2019 with a total sample of 12,442 people. Bivariable analyses assessed demographics among those who took more or less parental leave and estimated the prevalence of not accessing postpartum care by demographics, stratified by leave length. We used propensity score weighting to estimate the predicted risk and risk ratios of not accessing postpartum care with < 7 as compared to > = 7 weeks of leave, stratified by income.

RESULTS

There were significant differences in the prevalence of not accessing care stratified by leave duration, and disparities in utilization by race, ethnicity, and income. A shorter leave duration was associated with a higher risk of not accessing care (RR: 1.98 [CI 1.25-3.20] in higher income group, RR: 1.45 [CI 1.08, 1.99] in lower). The absolute risk of not accessing care was highest in the lower income group regardless of leave duration, though patterns of increased utilization with longer leave duration were consistent in both groups.

CONCLUSIONS FOR PRACTICE

While shorter leave durations increased the risk of not attending postpartum care, those with lower incomes had the highest absolute risk of not attending care. Policies to support paid leave and extended leave duration are necessary, along with additional supports to increase postpartum care utilization, particularly among low-income families.

Harnessing Consumer Wearable Digital Biomarkers for Individualized Recognition of Postpartum Depression Using the All of Us Research Program Data Set: Cross-Sectional Study

BACKGROUND

Postpartum depression (PPD) poses a significant maternal health challenge. The current approach to detecting PPD relies on in-person postpartum visits, which contributes to underdiagnosis. Furthermore, recognizing PPD symptoms can be challenging. Therefore, we explored the potential of using digital biomarkers from consumer wearables for PPD recognition.

OBJECTIVE

The main goal of this study was to showcase the viability of using machine learning (ML) and digital biomarkers related to heart rate, physical activity, and energy expenditure derived from consumer-grade wearables for the recognition of PPD.

METHODS

Using the All of Us Research Program Registered Tier v6 data set, we performed computational phenotyping of women with and without PPD following childbirth. Intraindividual ML models were developed using digital biomarkers from Fitbit to discern between prepregnancy, pregnancy, postpartum without depression, and postpartum with depression (ie, PPD diagnosis) periods. Models were built using generalized linear models, random forest, support vector machine, and k-nearest neighbor algorithms and evaluated using the κ statistic and multiclass area under the receiver operating characteristic curve (mAUC) to determine the algorithm with the best performance. The specificity of our individualized ML approach was confirmed in a cohort of women who gave birth and did not experience PPD. Moreover, we assessed the impact of a previous history of depression on model performance. We determined the variable importance for predicting the PPD period using Shapley additive explanations and confirmed the results using a permutation approach. Finally, we compared our individualized ML methodology against a traditional cohort-based ML model for PPD recognition and compared model performance using sensitivity, specificity, precision, recall, and F1-score.

RESULTS

Patient cohorts of women with valid Fitbit data who gave birth included <20 with PPD and 39 without PPD. Our results demonstrated that intraindividual models using digital biomarkers discerned among prepregnancy, pregnancy, postpartum without depression, and postpartum with depression (ie, PPD diagnosis) periods, with random forest (mAUC=0.85; κ=0.80) models outperforming generalized linear models (mAUC=0.82; κ=0.74), support vector machine (mAUC=0.75; κ=0.72), and k-nearest neighbor (mAUC=0.74; κ=0.62). Model performance decreased in women without PPD, illustrating the method's specificity. Previous depression history did not impact the efficacy of the model for PPD recognition. Moreover, we found that the most predictive biomarker of PPD was calories burned during the basal metabolic rate. Finally, individualized models surpassed the performance of a conventional cohort-based model for PPD detection.

CONCLUSIONS

This research establishes consumer wearables as a promising tool for PPD identification and highlights personalized ML approaches, which could transform early disease detection strategies.

Differences between rural and urban residence in the detection and treatment of perinatal mood and anxiety disorders

BACKGROUND

Perinatal mood and anxiety disorders are common, serious complications of pregnancy. Disparities exist by race and income in the prevalence and treatment of these conditions, and overall treatment rates remain low. Outside of pregnancy, a small body of literature suggests that rural residency may contribute to higher rates of depression for those who identify as women. However, among more diverse populations, evidence suggests urban residency may be associated with higher rates of depression among women of color. It is not known whether these trends hold for mood and anxiety disorders during pregnancy and postpartum.

OBJECTIVE

We examined differences in the detection and treatment of perinatal mood and anxiety disorders by rural and urban residents and assessed if the observed differences varied by maternal race or ethnicity.

STUDY DESIGN

We conducted a cross-sectional study using linked Medicaid claims and birth certificate records from Oregon and South Carolina from 2016 to 2020. We identified perinatal mood and anxiety disorder diagnoses during the perinatal period (pregnancy and within 60 days postpartum) using International Classification of Disease 10th edition codes and enumerated receipt of pharmacotherapy and psychotherapy treatment using Medicaid claims. We used logistic regression models controlling for relevant clinical and sociodemographic characteristics to estimate associations between rural residence and mood disorder detection and treatment.

RESULTS

Among the 185,809 births in our sample, 27% of births (n=50,820) were to people who lived in rural areas and 73% (n=134,989) to those in urban areas. The prevalence of any perinatal mood and anxiety disorders diagnosis was higher for urban residents (19.5%) than for rural residents (18.0%; P<.001). Overall treatment rates were low among people with a perinatal mood and anxiety disorder (42% [n=14,789]). In our adjusted models, those living in urban areas had higher odds of a perinatal mood and anxiety disorder diagnosis (adjusted odds ratio, 1.059 [95% confidence interval, 1.059-1.059], P<.001). We found a significant interaction between maternal race and rurality (P<.001). When we stratified by race, we found that among those who identified as Black, the odds of a perinatal mood and anxiety disorder diagnosis were increased for urban residents (odds ratio, 1.188 [95% confidence interval, 1.188-1.188]), whereas among those who identified as White, there were no such increased odds (odds ratio, 1.027 [95% confidence interval, 0.843-1.252]).

CONCLUSION

We saw small but meaningful differences between rural and urban residents in perinatal mood and anxiety disorder diagnosis rates. We detected an interaction between race and rural vs urban maternal residence that impacted the observed differences. By elucidating the intersection between race and other sociodemographic factors, we hope more targeted and meaningful investments can be made in the communities most in need.

Early Postpartum Hospital Encounters among Patients with Genitourinary and Wound Infections during Hospitalization for Birth

OBJECTIVES

 This study aimed to assess the associations between genitourinary and wound infections during the birth hospitalization and early postpartum hospital encounters, and to evaluate clinical risk factors for early postpartum hospital encounters among patients with genitourinary and wound infections during the birth hospitalization.

STUDY DESIGN

 We conducted a population-based cohort study of births in California during 2016 to 2018 and postpartum hospital encounters. We identified genitourinary and wound infections using diagnosis codes. Our main outcome was early postpartum hospital encounter, defined as a readmission or emergency department (ED) visit within 3 days after discharge from the birth hospitalization. We evaluated the association of genitourinary and wound infections (overall and subtypes) with early postpartum hospital encounter using logistic regression, adjusting for sociodemographic factors and comorbidities and stratified by mode of birth. We then evaluated factors associated with early postpartum hospital encounter among patients with genitourinary and wound infections.

RESULTS

 Among 1,217,803 birth hospitalizations, 5.5% were complicated by genitourinary and wound infections. Genitourinary or wound infection was associated with an early postpartum hospital encounter among patients with both vaginal births (2.2%; adjusted risk ratio [aRR[: 1.26; 95% confidence interval [CI]: 1.17-1.36) and cesarean births (3.2%; aRR: 1.23; 95% CI: 1.15-1.32). Patients with a cesarean birth and a major puerperal infection or wound infection had the highest risk of an early postpartum hospital encounter (6.4 and 4.3%, respectively). Among patients with genitourinary and wound infections during the birth hospitalization, factors associated with an early postpartum hospital encounter included severe maternal morbidity, major mental health condition, prolonged postpartum hospital stay, and, among cesarean births, postpartum hemorrhage (p-value < 0.05).

CONCLUSION

 Genitourinary and wound infections during hospitalization for birth may increase risk of a readmission or ED visit within the first few days after discharge, particularly among patients who have a cesarean birth and a major puerperal infection or wound infection.

KEY POINTS

· In all, 5.5% of patients giving birth had a genitourinary or wound infection (GWI).. · A total of 2.7% of GWI patients had a hospital encounter within 3 days of discharge after birth.. · Major puerperal infection and wound infection had the highest risk of an early hospital encounter.. · Among GWI patients, several birth complications were associated with an early hospital encounter..

Hypertension in Pregnancy: Current Challenges and Future Opportunities for Surveillance and Research

Hypertension in pregnancy (HP) includes eclampsia/preeclampsia, chronic hypertension, superimposed preeclampsia, and gestational hypertension. In the United States, HP prevalence doubled over the last three decades, based on birth certificate data. In 2019, the estimated percent of births with a history of HP varied from 10.1% to 15.9% for birth certificate data and hospital discharge records, respectively. The use of electronic medical records may result in identifying an additional third to half of undiagnosed cases of HP. Individuals with gestational hypertension or preeclampsia are at 3.5 times higher risk of progressing to chronic hypertension and from 1.7 to 2.8 times higher risk of developing cardiovascular disease (CVD) after childbirth compared with individuals without these conditions. Interventions to identify and address CVD risk factors among individuals with HP are most effective if started during the first 6 weeks postpartum and implemented during the first year after childbirth. Providing access to affordable health care during the first 12 months after delivery may ensure healthy longevity for individuals with HP. Average attendance rates for postpartum visits in the United States are 72.1%, but the rates vary significantly (from 24.9% to 96.5%). Moreover, even among individuals with CVD risk factors who attend postpartum visits, approximately 40% do not receive counseling on a healthy lifestyle. In the United States, as of the end of September 2023, 38 states and the District of Columbia have extended Medicaid coverage eligibility, eight states plan to implement it, and two states proposed a limited coverage extension from 2 to 12 months after childbirth. Currently, data gaps exist in national health surveillance and health systems to identify and monitor HP. Using multiple data sources, incorporating electronic medical record data algorithms, and standardizing data definitions can improve surveillance, provide opportunities to better track progress, and may help in developing targeted policy recommendations.

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.

Development of the Ready to Care Survey for VA Women's Health Primary Care Provider

INTRODUCTION

Women Veterans are at increased risk for poor pregnancy outcomes and are increasingly using Veteran Affairs (VA) for maternity benefits. VA Women's Health Primary Care Providers (WH-PCPs) are well positioned to improve maternal outcomes for women Veterans, yet little is understood about their experience and comfort with perinatal care. The objective of this study was to develop and validate a survey that could be utilized to assess WH-PCPs' experience, comfort, and attitudes towards perinatal care.

METHODS

After a review of the literature, we adapted a previously published survey to address four content areas including clinical experience, comfort level, and attitudes towards perinatal care and knowledge of VA specific maternity services. This survey was piloted with five WH-PCPs before undergoing two rounds of content validation with content experts. Content validity indexes (CVI) were calculated based on the content experts' ratings. Qualitative feedback from the content experts were summarized and reviewed by the research team. The CVI and qualitative responses were utilized to guide the decision to revise, refine, or delete survey questions.

RESULTS

After the first round of content validation, we deleted three questions, revised three questions, and add three questions to the content areas of clinical experience and comfort. In the domain of attitudes towards perinatal care, we deleted one question and revised two questions and three questions were added to the knowledge of VA specific maternity services domain. After the second round of content validation, only one question was deleted from the attitudes domain.

DISCUSSION

We developed and validated the Ready to Care Survey for VA WH-PCP using two rounds of content validation. The final survey had face and content validity. This survey tool can be used to assess VA WH-PCP's knowledge and readiness in caring for Veterans of child-bearing age for operational and research needs.

Postpartum care for parent-infant dyads: A community midwifery model

INTRODUCTION

Postpartum health is in crisis in the United States, with rising pregnancy-related mortality and worsening racial inequities. The World Health Organization recommends four postpartum visits during the 6 weeks after childbirth, yet standard postpartum care in the United States is generally one visit 6 weeks after birth. We present community midwifery postpartum care in the United States as a model concordant with World Health Organization guidelines, describing this model of care and its potential to improve postpartum health for birthing people and babies.

METHODS

We conducted semi-structured interviews with 34 community midwives providing care in birth centers and home settings in Oregon and California. A multidisciplinary team analyzed data using reflexive thematic analysis.

RESULTS

A total of 24 participants were Certified Professional Midwives; 10 were certified nurse-midwives. A total of 14 midwives identified as people of color. Most spoke multiple languages. We describe six key elements of the community midwifery model of postpartum care: (1) multiple visits, including home visits; typically five to eight over six weeks postpartum; (2) care for the parent-infant dyad; (3) continuity of personalized care; (4) relationship-centered care; (5) planning and preparation for postpartum; and (6) focus on postpartum rest.

CONCLUSION

The community midwifery model of postpartum care is a guideline-concordant approach to caring for the parent-infant dyad and may address rising pregnancy-related morbidity and mortality in the United States.

Improving Equitable Postpartum Care in an Urban Private Clinic with Predominantly Black Patients

INTRODUCTION

Maternal health disparities based on race, ethnicity, and socioeconomic factors exist in the United States, with Black women experiencing significantly worse outcomes. With much of perinatal morbidity and mortality attributed to the postpartum period, attention to equitable postpartum care is necessary for addressing this disparity.

PROCESS

A rapid-cycle quality improvement initiative was implemented in an urban clinic serving predominantly Black, Medicaid-insured clients. Although baseline data indicated 95% of clients experienced comorbidities, only 65% attended a comprehensive postpartum visit (PPV). The project's goal was to improve equitable postpartum care by increasing PPV attendance and quality of postpartum care to 90% in 8 weeks. The clinical team was engaged throughout to promote organizational change within the clinic. A provider checklist was implemented to improve PPV care metrics, and shared decision-making was initiated surrounding contraception and mood disorders. A care log tracked clinical practice guideline adherence with regular feedback informing the change process.

OUTCOMES

Postpartum care improved across a variety of factors studied over 8 weeks. The provider checklist prompted a 78% documentation rate of PPV care metrics, and care log tracking reflected an ending PPV attendance rate of 93%. Client satisfaction with postpartum care education was measured using a Likert scale of 1 to 5 (1 = dissatisfied and 5 = satisfied) with a noted improvement from a baseline score of 4.3 to an overall mean of 4.8.

DISCUSSION

This quality initiative addressed a key factor in health equity for a predominantly Black, Medicaid-insured population in an urban clinic by raising PPV attendance rates above national standards of 90% and improving client satisfaction and the quality of care received during these visits. The project was low cost and created sustainable systems for maintaining evidence-based equitable care. Limitations included the coronavirus disease 19 pandemic, clinic staff turnover, and staff and client biases. Continued innovative research targeted at improving health equity is needed.

Preventive Primary Care in the Postpartum Year: The Role of Medicaid Delivery System Reform

INTRODUCTION

Preventive and primary care in the postpartum year is critical for future health and may be increased by primary care focused delivery system reform including implementation of Medicaid Accountable Care Organizations (ACO). This study examined associations of Massachusetts Medicaid ACO implementation with preventive visits in the postpartum year.

METHODS

The Massachusetts All-Payer Claims Database was used to identify births to privately-insured or Medicaid ACO-eligible individuals from January 1, 2016 to February 28, 2019. Comparing these groups before and after implementation, a propensity score weighted difference-in-difference design was used to analyze associations of Medicaid ACO implementation with any preventive care visit and any primary care physician (PCP) preventive visit within one year postpartum, controlling for other characteristics. Analyses were performed in 2023 and 2024.

RESULTS

Of the 110,601 births in the study population, 35.5% had any preventive care visit and 23.0% had any preventive PCP visit in the year postpartum, with higher rates of preventive visits among privately-insured individuals. In adjusted difference-in-difference analyses, relative to the pre-period, there was a 2.7 percentage point (pp) decrease (95% confidence interval [CI]: -4.3pp, -1.2pp) and 3.5 pp decrease (95% CI: -4.9pp, -2.0pp) in use of any preventive visits and any PCP preventive visits, respectively, for Medicaid-insured versus privately-insured individuals after ACO implementation.

CONCLUSIONS

Implementation of Massachusetts Medicaid ACOs was associated with decreases in receipt of preventive visits and preventive PCP visits for Medicaid-insured individuals relative to privately-insured individuals. Medicaid ACOs should consider potential implications of primary care access in the postpartum year for health across the lifecourse.

Screening for post-traumatic stress disorder following childbirth using the Peritraumatic Distress Inventory

BACKGROUND

Post-traumatic stress disorder (PTSD) following traumatic childbirth may undermine maternal and infant health, but screening for maternal childbirth-related PTSD (CB-PTSD) remains lacking. Acute emotional distress in response to a traumatic experience strongly associates with PTSD. The Peritraumatic Distress Inventory (PDI) assesses acute distress in non-postpartum individuals, but its use to classify women likely to endorse CB-PTSD is unknown.

METHODS

3039 women provided information about their mental health and childbirth experience. They completed the PDI regarding their recent childbirth event, and a PTSD symptom screen to determine CB-PTSD. We employed Exploratory Graph Analysis and bootstrapping to reveal the PDI's factorial structure and optimal cutoff value for CB-PTSD classification.

RESULTS

Factor analysis revealed two strongly correlated stable factors based on a modified version of the PDI: (1) negative emotions and (2) bodily arousal and threat appraisal. A score of 15+ on the modified PDI produced high sensitivity and specificity: 88 % with a positive CB-PTSD screen in the first postpartum months and 93 % with a negative screen.

LIMITATIONS

In this cross-sectional study, the PDI was administered at different timepoints postpartum. Future work should examine the PDI's predictive utility for screening women as closely as possible to the time of childbirth, and establish clinical cutoffs in populations after complicated deliveries.

CONCLUSIONS

Brief self-report screening concerning a woman's emotional reactions to childbirth using our modified PDI tool can detect those likely to endorse CB-PTSD in the early postpartum. This may serve as the initial step of managing symptoms to ultimately prevent chronic manifestations.

Association Between Recurrent Preeclampsia and Attendance at the Blood Pressure Monitoring Appointment After Birth

OBJECTIVE

To examine the association between recurrent preeclampsia and attendance at the standard of care blood pressure monitoring appointment after birth.

DESIGN

Retrospective cohort.

SETTING

Single Magnet-accredited hospital affiliated with an academic medical center.

PARTICIPANTS

Multiparous women who gave birth between 2010 and 2020 and were diagnosed with preeclampsia (N = 313).

METHODS

We divided participants into two groups: those with prior preeclampsia (n = 119) and those without prior preeclampsia (n = 194). Using logistic regression, we calculated unadjusted and adjusted odds ratios to estimate the association between attendance at the postpartum blood pressure (PPBP) monitoring appointment and prior preeclampsia. We also explored the relationship between attendance at the PPBP monitoring appointment and use of magnesium sulfate during labor and birth and the relationship between attendance at the PPBP monitoring appointment and use of maintenance antihypertensive medications.

RESULTS

In adjusted analysis, participants with prior preeclampsia were 66.4% less likely to attend the PPBP monitoring appointment compared with those without prior preeclampsia, adjusted OR = 0.34, 95% CI [0.18, 0.62]. Administration of magnesium sulfate during delivery admission and use of maintenance antihypertensive medications were not associated with a change in attendance at the PPBP appointment.

CONCLUSION

Further research on patient-perceived risk of recurrent preeclampsia and improvement of systems to facilitate postpartum follow-up is needed.

Prescriptive Authority for Direct Entry Midwives in Washington State: Increasing Client Access to Contraception

Improving health and achieving health equity includes access to sexual and reproductive health care for all populations, especially those most in need. However, access to life-saving and life-affirming contraception with an individual's chosen perinatal provider can be impeded by restrictive regulations that limit scope and practice authority. This is especially true for the majority of community and direct entry midwives in the United States who have historically been unable to legally provide effective contraceptive methods. Recently, licensed midwives in Washington state were the first in the nation to achieve prescriptive authority, enabling their clients to directly obtain contraception and access to medications for common prenatal and postpartum conditions. Sustained advocacy efforts in the state's capitol enabled the Midwives' Association of Washington State to build relationships over time with legislators and government agencies to achieve this long-term goal. We present a successful midwifery-led innovation that achieved scope expansion for licensed midwives whose practice authority was limited by restrictive laws. Lessons learned are described and strategies offered to aid midwives and their advocates in other locales who want to improve health equity and access to contraception. Midwives are well positioned to provide this essential care to individuals living in underserved rural and urban areas and those from historically marginalized communities, but their ability to do so is limited by restrictive legislation.

Call for Improved Fourth Trimester Care After Stillbirth

Women who experience stillbirths are at increased risk for severe maternal morbidity and mortality, which makes the postpartum period a critical time in which to address health conditions and prevent complications. However, research on the health care needs of women who experience stillbirths is scarce, and these women are often excluded from research on the postpartum period. Therefore, the purpose of this commentary is to identify gaps in the research on postpartum care after stillbirth, explain why current fourth trimester care guidelines in the United States are inadequate, and advocate for nursing research and practice to improve understanding of health care needs in the fourth trimester.

Pregnancy-related risk factors and receipt of postpartum care among Texas Medicaid pregnant enrollees: Opportunities for pharmacist services

BACKGROUND

The United States (US) experiences the highest rate of maternal mortality of similar countries. Postpartum care (PPC) focused on chronic disease management is potentially lifesaving, especially among pregnancies complicated by risk factors such as diabetes, hypertension, and mental health conditions (MHCs), which are conditions in which pharmacists can have an impact.

OBJECTIVE

To evaluate the prevalence of maternal mortality risk factors and their relationships with receipt of PPC among Texas Medicaid enrollees.

METHODS

A retrospective study included women with a delivery between 3/25/2014-11/1/2019 who were continuously enrolled in Texas Medicaid during the study period from 84 days pre-delivery to 60 days post-delivery. PPC was defined as ≥1 visit associated with postpartum follow-up services. Maternal mortality risk factors (diabetes, hypertension, and MHCs) during and after pregnancy were identified using diagnoses and medication utilization. Age, race/ethnicity, cesarean delivery, and preterm birth served as covariates. Multivariable logistic regression was used to address the study objective.

RESULTS

The sample (N = 617,010) was 26.5±5.7 years, primarily (52.8%) Hispanic, and 33.0% had cesarean deliveries and 9.3% had preterm births. Risk factor prevalence included: diabetes (14.0%), hypertension (14.3%), and MHCs during (6.3%) and after (9.1%) pregnancy. A majority (77.9%) had a PPC visit within 60 days of delivery. The odds of receiving PPC were 1.2 times higher for patients with diabetes (OR = 1.183; 95% CI = 1.161-1.206; P < 0.0001), 1.1 times higher for patients with hypertension (OR = 1.109; 95% CI= 1.089-1.130; P < 0.0001), and 1.1 times higher for patients with MHCs (OR=1.138; 95% CI = 1.108-1.170; P < 0.0001) than patients without, respectively.

CONCLUSION

Over three-quarters of Texas Medicaid pregnant enrollees received PPC within 60 days of delivery and risk factors were prevalent and predictive of receipt of PPC. Pharmacists can have a positive impact on maternal health by addressing hypertension, diabetes, and MHC risk factors.

Differences in Self-Reported and Billed Postpartum Visits Among Medicaid-Insured Individuals

Importance

State Medicaid programs have recently implemented several policies to improve access to health care during the postpartum period. Understanding whether these policies are succeeding will require accurate measurement of postpartum visit use over time and across states; however, current estimates of use vary substantially between data sources.

Objectives

To examine disagreement between postpartum visit use reported in the Pregnancy Risk Assessment Monitoring System (PRAMS) and Medicaid claims and assess whether insurance transitions from Medicaid at the time of childbirth to other insurance types after delivery are associated with the degree of disagreement.

Design, Setting, and Participants

This cross-sectional study was conducted among individuals in South Carolina after delivery who had completed a PRAMS survey and for whom Medicaid was the payer of their delivery care. PRAMS responses from 2017 to 2020 were linked to inpatient, outpatient, and physician Medicaid claims; survey-weighted logistic regression models were then used to examine the association between postpartum insurance transitions and data source disagreement. Data were analyzed from February through October 2023.

Exposure

Insurance transition type: continuous Medicaid, Medicaid to private insurance, Medicaid to no insurance, and Emergency Medicaid to no insurance.

Main Outcome and Measure

Data source disagreement due to reporting a postpartum visit in PRAMS without a Medicaid claim for a visit or having a Medicaid claim for a visit without reporting a postpartum visit in PRAMS.

Results

Among 836 PRAMS respondents enrolled in Medicaid at delivery (663 aged 20-34 years [82.9%]), a mean of 85.7% (95% CI, 82.1%-88.7%) reported a postpartum visit in PRAMS and a mean of 61.6% (95% CI, 56.9%-66.0%) had a Medicaid claim for a postpartum visit. Overall, 253 respondents (30.3%; 95% CI, 26.1%-34.7%) had data source disagreement: 230 individuals (27.2%; 95% CI, 23.2%-31.5%) had a visit in PRAMS without a Medicaid claim, and 23 individuals (3.1%; 95% CI, 1.8%-5.2%) had a Medicaid claim without a visit in PRAMS. Compared with individuals continuously enrolled in Medicaid, those who transitioned to private insurance after delivery and those who were uninsured after delivery and had Emergency Medicaid at delivery had an increase in the probability of data source agreement of 15.8 percentage points (95% CI, 2.6-29.1 percentage points) and 37.2 percentage points (95% CI, 19.6-54.8 percentage points), respectively.

Conclusions and Relevance

This study's findings suggest that Medicaid claims may undercount postpartum visits among people who lose Medicaid or switch to private insurance after childbirth. Accounting for these insurance transitions may be associated with better claims-based estimates of postpartum care.

Using a Patient Educational Video to Improve Knowledge of Maternal Mortality Warning Signs: A Randomized Controlled Trial

OBJECTIVE

To determine whether a community-informed, language-concordant postpartum video education campaign, developed with community input, improves patients' knowledge of warning signs for postpartum maternal mortality (infection, hemorrhage, hypertensive disorders, and postpartum depression) compared with routine discharge procedures.

METHODS

A single-center, investigator-blinded, parallel-group randomized controlled trial of postpartum individuals who delivered at a large, urban, tertiary care hospital. Eligible participants were enrolled and completed a baseline knowledge questionnaire. After delivery, they were randomized to routine discharge education (control) or routine education plus video education (intervention). After discharge education, patient knowledge was again assessed in both groups before participants left the hospital. The primary outcome was the percentage of participants who showed improvement in their knowledge, measured by the number of correct questionnaire responses after education compared with their baseline, assessed as a binary outcome. A sample size of 150 (75 per group) was planned to detect a 25% absolute increase in the frequency of the primary outcome.

RESULTS

From July to August 2022, 296 participants were screened and 200 were randomized (100 per group). Eighty-two percent of participants had college or graduate education, and 71.5% had commercial insurance. There was no significant difference in baseline characteristics. There was no statistically significant difference in the percentage of participants who improved their scores between the baseline and posteducation questionnaires (64.5% vs 50.0%, P =.09). However, the median posteducation questionnaire total score was significantly higher in the video education group (14 [interquartile range 12-15] vs 13 [interquartile range 12-14], P =.003). In addition, they more frequently reported that video education was "very helpful" (83.9% vs 72.5%, P =.23) and that they were "very satisfied" with their education (86.1% vs 75.5%, P =.29).

CONCLUSION

Enhanced postpartum education through a novel video did not result in a statistically significant difference in frequency of improved score on the posteducation questionnaires but was associated with increased satisfaction with care.

Harnessing consumer wearable digital biomarkers for individualized recognition of postpartum depression using the All of Us Research Program dataset

Postpartum depression (PPD), afflicting one in seven women, poses a major challenge in maternal health. Existing approaches to detect PPD heavily depend on in-person postpartum visits, leading to cases of the condition being overlooked and untreated. We explored the potential of consumer wearable-derived digital biomarkers for PPD recognition to address this gap. Our study demonstrated that intra-individual machine learning (ML) models developed using these digital biomarkers can discern between pre-pregnancy, pregnancy, postpartum without depression, and postpartum with depression time periods (i.e., PPD diagnosis). When evaluating variable importance, calories burned from the basal metabolic rate (calories BMR) emerged as the digital biomarker most predictive of PPD. To confirm the specificity of our method, we demonstrated that models developed in women without PPD could not accurately classify the PPD-equivalent phase. Prior depression history did not alter model efficacy for PPD recognition. Furthermore, the individualized models demonstrated superior performance compared to a conventional cohort-based model for the detection of PPD, underscoring the effectiveness of our individualized ML approach. This work establishes consumer wearables as a promising avenue for PPD identification. More importantly, it also emphasizes the utility of individualized ML model methodology, potentially transforming early disease detection strategies.

Variation in Outpatient Postpartum Care Use in the United States: A Latent Class Analysis

INTRODUCTION

Despite efforts to improve postpartum health care in the United States, little is known about patterns of postpartum care beyond routine postpartum visit attendance. This study aimed to describe variation in outpatient postpartum care patterns.

METHODS

In this longitudinal cohort study of national commercial claims data, we used latent class analysis to identify subgroups of patients (classes) with similar outpatient postpartum care patterns (defined by the number of preventive, problem, and emergency department outpatient visits in the 60 days after birth). We also compared classes in terms of maternal sociodemographics and clinical characteristics measured at childbirth, as well as total health spending and rates of adverse events (all-cause hospitalizations and severe maternal morbidity) measured from childbirth to the late postpartum period (61-365 days after birth).

RESULTS

The study cohort included 250,048 patients hospitalized for childbirth in 2016. We identified six classes with distinct outpatient postpartum care patterns in the 60 days after birth, which we classified into three broad groups: no care (class 1 [32.4% of the total sample]); preventive care only (class 2 [18.3%]); and problem care (classes 3-6 [49.3%]). The prevalence of clinical risk factors at childbirth increased progressively from class 1 to class 6; for example, 6.7% of class 1 patients had any chronic disease compared with 15.5% of class 5 patients. Severe maternal morbidity was highest among the high problem care classes (classes 5 and 6): 1.5% of class 6 patients experienced severe maternal morbidity in the postpartum period and 0.5% in the late postpartum period, compared with less than 0.1% of patients in classes 1 and 2.

CONCLUSIONS

Efforts to redesign and measure postpartum care should reflect the current heterogeneity in care patterns and clinical risks in the postpartum population.

The Postpartum Period: An Opportunity for Alcohol Screening and Counseling to Reduce Adverse Health Impacts

OBJECTIVES

The postpartum period presents an opportunity to engage in discussions about alcohol consumption and related health harms. This study examined the prevalence of alcohol consumption among a sample of postpartum persons with a recent live birth and screening and brief intervention (alcohol SBI) or counseling by their providers.

METHODS

We analyzed 2019 data from a telephone survey conducted 9 to 10 months postpartum among individuals who responded to the standard Pregnancy Risk Assessment Monitoring System survey in 6 states. Weighted prevalence estimates were calculated for alcohol consumption and alcohol SBI after birth through up to 10 months postpartum.

RESULTS

Among 1790 respondents, 53.1% reported consuming alcohol postpartum. Among those who drank postpartum, 70.8% reported being asked about alcohol use by a healthcare provider. Slightly more than half of respondents who drank postpartum and were trying to get pregnant (52.4%) or were not using birth control at the time of the survey (59.8%) reported being asked about alcohol use. Approximately 25% of respondents who drank alcohol postpartum were advised about risky alcohol levels by a healthcare provider. Small proportions of individuals who drank alcohol postpartum and were pregnant or trying to get pregnant at the time of the survey were advised to reduce or stop drinking alcohol (10.6% and 2.3%, respectively).

CONCLUSIONS

These findings suggest missed opportunities to promote health and prevent adverse alcohol-related health outcomes during the postpartum period through evidence-based tools such as alcohol SBI.

Postpartum Home Blood Pressure Monitoring Program: Improving Care for Hypertension During Postpartum after a Hospital Birth

BACKGROUND AND SIGNIFICANCE

Hypertensive disorders of pregnancy complicate about 10% of pregnancies and are a leading cause of maternal morbidity and mortality.

PURPOSE

The purpose of this quality improvement project was to evaluate a program to provide a home blood pressure monitor to all postpartum patients who had a hypertensive diagnosis and elevated blood pressure.

METHODS

The program includes a blood pressure monitor, instructions for its use, education about hypertension, and a guidance grid with standardized blood pressure parameters reviewed prior to discharge from the hospital. Patients are taught about potential adverse outcomes during postpartum. Patients are instructed to follow-up with their care provider based on the parameters. A retrospective medical record review was used to evaluate clinical outcomes.

RESULTS

Medical records of 185 patients indicated that 20% ( n = 36) who received the home BP monitor reported one or more mild-to-severe range blood pressure(s) during postpartum. Twenty-eight percent ( n = 52) had outpatient medication adjustments, including decreasing, increasing, starting, and discontinuing medications. Nine percent ( n = 17) of patients returned to the obstetric triage for evaluation. There was patient overlap between those experiencing elevated blood pressures, medication adjustments, and those who returned to hospital for evaluation.

CLINICAL IMPLICATIONS

Ongoing monitoring may improve identification and management of postpartum hypertension and potentially prevent progression to hypertensive-related adverse events.

Screening for Post-Traumatic Stress Disorder following Childbirth using the Peritraumatic Distress Inventory

Background

Maternal psychiatric morbidities include a range of psychopathologies; one condition is post-traumatic stress disorder (PTSD) that develops following a traumatic childbirth experience and may undermine maternal and infant health. Although assessment for maternal mental health problems is integrated in routine perinatal care, screening for maternal childbirth-related PTSD (CB-PTSD) remains lacking. Acute emotional distress in response to a traumatic event strongly associates with PTSD. The brief 13-item Peritraumatic Distress Inventory (PDI) is a common tool to assess acute distress in non-postpartum individuals. How well the PDI specified to childbirth can classify women likely to endorse CB-PTSD is unknown.

Objectives

We sought to determine the utility of the PDI to detect CB-PTSD in the early postpartum period. This involved examining the psychometric properties of the PDI specified to childbirth, pertaining to its factorial structure, and establishing an optimal cutoff point for the classification of women with high vs. low likelihood of endorsing CB-PTSD.

Study Design

A sample of 3,039 eligible women who had recently given birth provided information about their mental health and childbirth experience. They completed the PDI regarding their recent childbirth event, and a PTSD symptom screen to determine CB-PTSD. We employed Exploratory Graph Analysis (EGA) and bootstrapping analysis to reveal the factorial structure of the PDI and the optimal PDI cutoff value for CB-PTSD classification.

Results

Factor analysis of the PDI shows two strongly correlated stable factors based on a modified 12-item version of the PDI consisting of (1) negative emotions and (2) bodily arousal and threat appraisal in regard to recent childbirth. This structure largely accords with prior studies of individuals who experienced acute distress resulting from other forms of trauma. We report that a score of 15 or higher on the modified PDI produces strong sensitivity and specificity. 88% of women with a positive CB-PTSD screen in the first postpartum months and 93% with a negative screen are identified as such using the established cutoff.

Conclusions

Our work reveals that a brief self-report screening concerning a woman's immediate emotional reactions to childbirth that uses our modified PDI tool can detect women likely to endorse CB-PTSD in the early postpartum period. This form of maternal mental health assessment may serve as the initial step of managing symptoms to ultimately prevent chronic symptom manifestation. Future research is needed to examine the utility of employing the PDI as an assessment performed during maternity hospitalization stay in women following complicated deliveries to further guide recommendations to implement maternal mental health screening for women at high risk for developing CB-PTSD.

Maternal Centric Measurement and Data Gaps in Addressing Maternal Morbidities: A Scoping Review

OBJECTIVE

The objectives of this project were to (1) describe maternal-centric measures and survey data which are publicly available to evaluate the incidence, frequency, and distribution of maternal morbidity in the postpartum period, and (2) to identify postpartum care quality improvement targets and outline the types of measurement and data required to support them.

METHODS

We conducted a scoping review of two types of data sources: maternal health quality measures used by providers and payers and nationally-representative survey data sets administered by federal agencies. Each source was searched for keywords associated with pregnancy and the postpartum period. We included quality measures and survey questions that are maternal-centric and addressed the postpartum period. We excluded infant-centric measures and data. Quality measures were organized according to the Donabedian quality model.

RESULTS

Our analysis demonstrates that existing maternal-centric quality measures and survey data offer limited insight into diagnosis and patient care delivery experiences associated with maternal morbidities during the postpartum period.

CONCLUSION

There is inadequate maternal-centric data on the incidence, frequency, and distribution of postpartum maternal morbidities and associated care use. This gap reduces the ability of research to estimate the incidence of illness and injury among postpartum women and create targeted quality improvement efforts. Our findings highlight the need for quality measure stewards and data sponsors to enhance data collection and methods to become more inclusive of maternal-centric outcomes during the postpartum period.

Perinatal Mental Health Disorders: A Review of Lessons Learned from Obstetric Care Settings

Perinatal mental health has garnered significant attention within obstetrics over the last couple of decades as the long- and short-term morbidities of untreated perinatal mental health disorders on both the mother and fetus/neonate have become increasingly apparent. There have been major strides in increasing screening for perinatal mental health disorders, clinician comfort with prescribing common psychiatric medications, and integrating mental health professionals into prenatal care via health services approaches such as the collaborative care model. Despite these advances, however, gaps still remain in the tools used for screening and diagnosis, obstetric clinician training in diagnosis and management of perinatal mood and anxiety disorders, as well as patient access to mental health care during pregnancy and especially postpartum. Herein we review the state of perinatal mental health from the perspective of the obstetric provider and identify areas of ongoing innovation.

Postpartum Care Visit Attendance Within 60 Days of Delivery Among Women With and Without Opioid Use During Pregnancy: An Analysis of Commercial Insurance Data

BACKGROUND

Postpartum care (PPC) is a key component of maternal health, particularly for people who use opioids during pregnancy. Little is known about the prevalence and correlates of PPC visit attendance among those using opioids compared with nonusers in a privately insured population.

METHODS

A retrospective cohort study was conducted using nationwide private insurance claims between 2011 and 2017 (N = 1,291,352 women) comparing the following opioid use groups: nonusers, nonchronic prescription users, chronic prescription users, and women with opioid use disorder (OUD). Multivariable logistic and linear regressions evaluated the odds of PPC attendance and the mean time to an initial PPC visit for each user group. Stratified models identified factors associated with PPC attendance by opioid use type.

RESULTS

Overall, 45% of the cohort attended a PPC visit and nearly 10% had any opioid use during pregnancy. More women in the three opioid use categories attended PPC than nonusers (50-56% vs. 45%). Opioid use regardless of type was associated with higher odds and earlier PPC visitation than women with no opioid use; nonchronic and chronic users had 17% and 40% greater odds of PPC than nonusers (adjusted odds ratio [aOR]: 1.17; 95% confidence interval [CI]: 1.16-1.19; aOR: 1.40, 95% CI: 1.34-1.46), whereas women with OUD had 7% higher odds (aOR: 1.07; 95% CI: 1.00-1.13). Antenatal care and psychiatric, hypertensive, and pain conditions were most strongly associated with higher odds of attending PPC; older maternal age was negatively associated with PPC. Stratified analysis showed opioid correlates varied similarly across user groups.

CONCLUSIONS

PPC use was generally low in this study cohort of privately insured women. Women who used opioids and those with chronic conditions had greater odds of attending PPC. Improved efforts are needed to engage people in PPC, as well as service integration and coordination for people who use opioids during pregnancy.

Association Between the Coronavirus Disease 2019 (COVID-19) Pandemic and National Disparities in Postpartum Visit Attendance

This study used data from PRAMS (Pregnancy Risk Assessment Monitoring System) between 2016 and 2020 and found that postpartum visit attendance declined by 5.8 (95% CI -6.4 to -5.2) percentage points in the first 9 months of the coronavirus disease 2019 (COVID-19) pandemic. The greatest declines occurred among non-Hispanic Black individuals (-9.9, 95% CI -11.6 to -8.1 percentage points), individuals aged 19 years or younger (-9.9, 95% CI -13.5 to -6.2 percentage points), and individuals without postpartum insurance (-11.4, 95% CI -14.5 to -8.3 percentage points). Although the pandemic was associated with a decrease in reporting common barriers to attendance, including lack of transportation and not being able to leave work, it introduced new barriers that potentially contributed to widened disparities in postpartum care. A combination of health policy and health system approaches are needed to increase postpartum visit attendance and reduce disparities in use.

Association of Health Insurance, Geography, and Race and Ethnicity With Disparities in Receipt of Recommended Postpartum Care in the US

Importance

Little is known about the quality of postpartum care or disparities in the content of postpartum care associated with health insurance, rural or urban residency, and race and ethnicity.

Objectives

To examine receipt of recommended postpartum care content and to describe variations across health insurance type, rural or urban residence, and race and ethnicity.

Design, Settings, and Participants

This cross-sectional survey of patients with births from 2016 to 2019 used data from the Pregnancy Risk Assessment Monitoring System (43 states and 2 jurisdictions). A population-based sample of patients conducted by state and local health departments in partnership with the Centers for Disease Control and Prevention were surveyed about maternal experiences 2 to 6 months after childbirth (mean weighted response rate, 59.9%). Patients who attended a postpartum visit were assessed for content at that visit. Analyses were performed November 2021 to July 2022.

Exposures

Medicaid or private health insurance, rural or urban residence, and race and ethnicity (non-Hispanic White or racially minoritized groups).

Main Outcomes and Measures

Receipt of 2 postpartum care components recommended by national quality standards (depression screening and contraceptive counseling), and/or other recommended components (smoking screening, abuse screening, birth spacing counseling, eating and exercise discussions) with estimated risk-adjusted predicted probabilities and percentage-point (pp) differences.

Results

Among the 138 073 patient-respondents, most (59.5%) were in the age group from 25 to 34 years old; 59 726 (weighted percentage, 40%) were insured by Medicaid; 27 721 (15%) were rural residents; 9718 (6%) were Asian, 24 735 (15%) were Black, 22 210 (15%) were Hispanic, 66 323 (60%) were White, and fewer than 1% were Indigenous (Native American/Alaska Native) individuals. Receipt of both depression screening and contraceptive counseling both significantly lower for Medicaid-insured patients (1.2 pp lower than private; 95% CI, -2.1 to -0.3), rural residents (1.3 pp lower than urban; 95% CI, -2.2 to -0.4), and people of racially minoritized groups (0.8 pp lower than White individuals; 95% CI, -1.6 to -0.1). The highest receipt of these components was among privately insured White urban residents (80%; 95% CI, 79% to 81%); the lowest was among privately insured racially minoritized rural residents (75%; 95% CI, 72% to 78%). Receipt of all other components was significantly higher for Medicaid-insured patients (6.1 pp; 95% CI, 5.2 to 7.0), rural residents (1.1 pp; 95% CI, 0.1 to 2.0), and people of racially minoritized groups (8.5 pp; 95% CI, 7.7 to 9.4). The highest receipt of these components was among Medicaid-insured racially minoritized urban residents (34%; 95% CI, 33% to 35%), the lowest was among privately insured White urban residents (19%; 95% CI, 18% to 19%).

Conclusions and Relevance

The findings of this cross-sectional survey of postpartum individuals in the US suggest that inequities in postpartum care content were extensive and compounded for patients with multiple disadvantaged identities. Examining only 1 dimension of identity may understate the extent of disparities. Future studies should consider the content of postpartum care visits.

Racial/Ethnic Disparities in Postpartum Health Insurance Coverage Among Rural and Urban U.S. Residents

Objective: Half of maternal deaths occur during the postpartum year, with data suggesting greater risks among Black, Indigenous, and people of color (BIPOC) and rural residents. Being insured after childbirth improves postpartum health-related outcomes, and recent policy efforts focus on extending postpartum Medicaid coverage from 60 days to 1 year postpartum. The purpose of this study is to describe postpartum health insurance coverage for rural and urban U.S. residents who are BIPOC compared to those who are white. Materials and Methods: Using data from the 2016-2019 Pregnancy Risk Assessment Monitoring System (n = 150,273), we describe health insurance coverage categorized as Medicaid, commercial, or uninsured at the time of childbirth and postpartum. We measured continuity of insurance coverage across these periods, focusing on postpartum Medicaid disruptions. Analyses were conducted among white and BIPOC residents from rural and urban U.S. counties. Results: Three-quarters (75.3%) of rural white people and 85.3% of urban white people were continuously insured from childbirth to postpartum, compared to 60.5% of rural BIPOC people and 65.6% of urban BIPOC people. Postpartum insurance disruptions were frequent among people with Medicaid coverage at childbirth, particularly among BIPOC individuals, compared to those with private insurance; 17.0% of rural BIPOC residents had Medicaid at birth and became uninsured postpartum compared with 3.4% of urban white people. Conclusions: Health insurance coverage at childbirth, postpartum, and across these timepoints varies by race/ethnicity and rural compared with urban residents. Policy efforts to extend postpartum Medicaid coverage may reduce inequities at the intersection of racial/ethnic identity and rural geography.
