Abstract

BACKGROUND: Peripartum cardiomyopathy (PPCM) is a rare medical condition presenting as idiopathic heart failure. The aim of this study was to (1) examine the contribution of neighborhood disinvestment to PPCM risk and to racial and ethnic disparities in PPCM; (2) examine the extent to which sociodemographic factors and chronic hypertension explain these outcomes; and (3) describe severe maternal morbidity cases and the timing of PPCM. METHODS: We conducted an observational cohort study using vital records longitudinally linked with hospital discharge records for mothers and infants up to 9 months postpartum for births in California from 1997 to 2019. Using the Neighborhood Deprivation Index as a proxy measure for neighborhood disinvestment, we sequentially adjusted multivariable logistic regression models to estimate the association of Neighborhood Deprivation Index and race and ethnicity with PPCM. RESULTS: Our study included 7 354 662 births and 918 (0.012%) PPCM cases. Those residing in neighborhoods with higher disinvestment had an increased odds of PPCM (OR [95% CI] Quartile 2: 1.2 [1.0–1.5]; Quartile 3: 1.7 [1.4–2.1]; Quartile 4: 1.5 [1.2–1.9]). When considering the contribution of Neighborhood Deprivation Index to racial and ethnic disparities in PPCM, the odds ratio slightly decreased for Non-Hispanic Black births from 3.8 (3.1–4.6) to 3.4 (2.8–4.1). For chronic hypertension in Non-Hispanic Black births there was a slight decrease in odds from 3.4 (2.8–4.1) to 3.1 (2.6–3.8). The severe maternal morbidity indicator with the highest frequency was pulmonary edema/acute heart failure. CONCLUSIONS: Our results show that neighborhood deprivation and pre-pregnancy hypertension partially explain PPCM risk but does not explain the racial or ethnic disparity. Future research should examine the impact of specific measures of neighborhood deprivation on the racial and ethnic disparity in outcomes such as PPCM.

Abstract

Background: Cesarean birth increases risk of maternal morbidity and mortality. Purpose: Examine the relationship between labor and delivery staffing and hospital cesarean and vaginal birth after cesarean (VBAC) rates. Methods: Survey of U.S. labor nurses in 2018 and 2019 on adherence to AWHONN nurse staffing standards with data linked to American Hospital Association Survey data, patient discharge data, and cesarean birth and VBAC rates. Findings: In total, 2,786 nurses from 193 hospitals in 23 states were included. Mean cesarean rate was 27.3% (SD 5.9, range 11.7%–47.2%); median VBAC rate 11.1% (IQR 1.78%–20.2%; range 0%–40.1%). There was relatively high adherence to staffing standards (mean, 3.12 of possible 1–4 score). After adjusting for hospital characteristics, nurse staffing was an independent predictor of hospital-level cesarean and VBAC rates (IRR 0.89, 95% CI 0.84–0.95 and IRR 1.58, 95% CI 1.25–1.99, respectively). Discussion: Better nurse staffing predicted lower cesarean birth rates and higher VBAC rates. Conclusion: Hospitals should be accountable for providing adequate nurse staffing during childbirth.

Abstract

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.

Abstract

Background: Interprofessional simulation-based team training (ISBTT) is commonly used to optimize interprofessional teamwork in healthcare. The literature documents the benefits of ISBTT, yet effective interprofessional collaboration continues to be challenged by complex hierarchies and power dynamics. Explicitly addressing these issues during ISBTT may help participants acquire skills to navigate such challenges, but guidelines on how to do this are limited. Methods: We applied an educational design research approach to develop and pilot structured facilitator guidelines that explicitly address power and hierarchy with interprofessional teams. We conducted this work in a previously established ISBTT program at our institution, between September 2020 and December 2021. We first reviewed the literature to identify relevant educational theories and developed design principles. We subsequently designed, revised, and tested guidelines. We used qualitative thematic and content analysis of facilitator interviews and video-recording of IBSTT sessions to evaluate the effects of the guidelines on the pre- and debriefs. Results: Qualitative content analysis showed that structured guidelines shifted debriefing participation and content. Debriefings changed from physician-led discussions with a strong focus on medical content to conversations with more equal participation by nurses and physicians and more emphasis on teamwork and communication. The thematic analysis further showed how the conversation during debriefing changed and how interprofessional learning improved after the implementation of the guidelines. While power and hierarchy were more frequently discussed, for many facilitators these topics remained challenging to address. Conclusion: We successfully created and implemented guidelines for ISBTT facilitators to explicitly address hierarchy and power. Future work will explore how this approach to ISBTT impacts interprofessional collaboration in clinical practice.

Abstract

Background: Efforts to reduce cesarean birth overuse have had varied success. De-implementation strategies that incorporate change to organizational characteristics (i.e. culture) can improve adoption and sustainability. This study aimed to identify culture change strategies used by hospitals that achieved significant and sustained cesarean reduction and eliminated racial disparities in cesarean birth. Methods: Hospitals in California and Florida that (1) engaged in quality initiatives to reduce cesarean births; (2) demonstrated at least a 5% cesarean birth reduction; and (3) sustained the reduction for 18 months after participation were invited to participate. Hospitals that reduced also cesarean racial disparity were prioritized for recruitment. Qualitative, semi-structured interviews were performed with leaders, obstetricians, family physicians, midwives, and nurses providing intrapartum care. Reflexive thematic analysis and values coding were used. Results: 35 participants from 6 hospitals (3 in California, 3 in Florida) participated in interviews or focus groups. Nurse-focused strategies included: leadership demonstrating support for proactive labor support (e.g., Spinning Babies, comfort measures, nursing time at bedside); enhanced communication through inter-disciplinary team huddles; clear delineation of roles; and a chain of command that assured nurses could advocate for their patients freely and without retribution. Physician-focused strategies included regular and publicly visible feedback delivered by trusted messengers, drawing attention to successful vaginal births, and highlighting the contributions of labor support. A theme of hiring/retaining for “fit” was articulated at all hospitals, most notably, the hospital that eliminated their cesarean birth racial disparity, where “fit” was conceptualized as empathy, humanism, and a desire to meet community needs. Conclusions: This study identified specific de-implementation strategies for hospitals to change implementation context, namely culture, to achieve and sustain reduction of cesarean birth. Hospitals looking to sustain culture change should adapt strategies to align with existing clinician values, change attitudes through sharing successful vaginal births, and modify beliefs through education from trusted messengers. Strategies to reduce racial disparities should emphasize designing teams that are aware of and prioritize community needs, including hiring staff from the local community, and partnering with community-based organizations.

Abstract

Introduction: Symptoms of untreated depression and anxiety during pregnancy are associated with serious adverse effects for the pregnant person, birth outcomes, and child development. However, pregnant persons are less likely to be screened and treated compared with nonpregnant people. In this systematic review, we aimed to explore individual, provider, and systems factors that impact screening, identification, and treatment patterns for depression and anxiety during pregnancy. Methods: Studies were eligible for inclusion if they were conducted within the United States and published in English between January 2012 and January 2023. Each study included analysis that compared rates of screening, identification, or treatment engagement and explicitly discussed disparities or health equity in marginalized groups. Fifteen articles met full inclusion criteria. Results: Results demonstrated variation in the screening, identification, and treatment of depression and anxiety during pregnancy among diverse groups of patients. Screening rates ranged from 51.3% in Puerto Rico to 90.7% in Alaska. Among specific clinical populations, rates were as low as 2.0%. Fewer than half of patients were referred to treatment when indicated by screening or diagnoses. Patient characteristics such as age, race, ethnicity, socioeconomic and health factors, mental health history, and obesity were associated with variation in the rates of screening, diagnoses, or treatment engagement. Language factors were the most common factor associated with lower rates of screening and treatment access. Discussion: Results suggest that many pregnant people are being overlooked and lack appropriate referrals or resources to access treatment. Results are consistent with previous findings that role confusion and lack of time, provider training, and interest contribute to low rates of screening and treatment. Future research must focus on system level factors to address perceived barriers to screening and treating depression and anxiety during pregnancy in a systematic and equitable way.

Abstract

INTRODUCTION: Pregnancy represents a stressful period for both women and their families. Whether the family maintains functioning during pregnancy could have significant implications on maternal and child health. In this study, we explored individual- and family-level factors associated with family functioning in adolescent and young adult mothers.METHODS: This study was a secondary analysis of 295 young mothers, ages between 15 and 21 years. Multivariate logistic regression models were conducted to estimate adjusted odds ratios of exploratory factors on the risk of being in high family functioning group. The parent study was approved by the Institutional Review Boards at Yale University.RESULTS: The mean score of family functioning was 5.14 out of 7. With the inclusion of individual-level factors (Model 1), significant associations were observed between high family functioning and having ever attended religious services (OR = 2.22, 95% CI: 1.20-4.09), low perceived discrimination (OR = 3.04, 95% CI: 1.60-5.75), and high perceived social support (OR = 3.74, 95% CI: 2.01-6.95). After including both individual- and family-level factors (Model 2), results identified significant associations between high family functioning and annual household income>$15,000 (OR = 9.82, 95% CI: 1.67-57.67, p = 0.011) and no experience of violence from any family members (OR = 4.94, 95% CI: 1.50-16.21, p = 0.008).DISCUSSION: The models of care should be structured to support the continuity of maternity care in which health care providers have the opportunity to discover and utilize each family's strengths to provide the optimal caring experience for young mothers and their families as a unit.

Abstract

Background: Some breastfeeding mothers try to increase their milk supply through pharmaceutical, dietary, and behavioral strategies that vary in effectiveness. Information seeking behaviors may influence which strategies mothers use. Objective: To describe where mothers obtain information about increasing milk supply, describe the perceived influence of each information source on decision-making about strategies for increasing milk supply, and explore associations between information sources and mothers' use of galactagogues (i.e., pharmaceutical and dietary strategies) and behavioral strategies. Methods: Women who were currently breastfeeding and living in the United States were recruited through Facebook advertisements to complete an online survey between December 2020 and February 2021. Descriptive statistics were calculated, and chi-square tests compared participants' use of galactagogues and behavioral strategies by information sources. Results: Participants were 1,351 breastfeeding mothers (81% non-Hispanic white; 47% first-time breastfeeding; 21% Special Supplemental Nutrition Program for Women, Infants, and Children participants). Nearly all participants (97%) obtained information about increasing milk supply from at least one source, most commonly lactation consultants (68%), Facebook (61%), search engines (50%), websites (47%), and nurses (41%). There was high variability in the perceived influence of each source on decision-making. Galactagogue use was higher among participants who obtained information from the internet (Yes: 68% vs. No: 43%, p < 0.000), social media (Yes: 65% vs. No: 40%, p < 0.000), family and friends (Yes: 65% vs. No: 53%, p < 0.000), and lactation consultants (Yes: 63% vs. No: 54%, p < 0.002). Behavioral strategies were more commonly reported among participants who accessed these same sources, maternal health care professionals (Yes: 98% vs. No: 91%, p < 0.000), and pediatricians (Yes: 98% vs. No: 94%, p = 0.001). Conclusion: Breastfeeding mothers commonly obtained information about increasing milk supply from a variety of sources. Information sources accessed were associated with mothers' use of galactagogues and behavioral strategies for increasing milk supply.

Abstract

Objective: To qualitatively describe breastfeeding experiences among mothers who used galactagogues to increase their milk supply. Design: One-time, semistructured phone interviews. Setting: US. Participants: Breastfeeding mothers (n = 19) who reported ever consuming foods, beverages, or herbal supplements to increase their milk supply in a cross-sectional online survey were purposefully sampled to participate in this qualitative study. Participants were diverse in terms of race and ethnicity, education, income, infant age (0–18 months), and prior breastfeeding experience (32% first-time breastfeeding). Phenomenon of Interest: Reasons for trying to increase milk supply, sources of information about increasing milk supply, and strategies tried to increase milk supply. Analysis: Interviews were transcribed verbatim and analyzed using reflexive thematic analysis. Results: Participants expressed determination and commitment to breastfeeding but unexpectedly struggled to breastfeed and increase their milk supply. They sought information from multiple sources and used individualized approaches to address milk supply concerns on the basis of recommendations from others, as well as the perceived convenience, cost, palatability, and safety of potential strategies. Conclusions and Implications: Results suggest a need to expand breastfeeding education and support so that lactating parents anticipate common breastfeeding challenges and are aware of evidence-based strategies for increasing their milk supply.
