Abstract

Despite long-existing calls to address alarming racial/ethnic gaps in severe maternal morbidity (SMM), research that considers the impact of intersecting social inequities on SMM risk remains scarce. Invoking intersectionality theory, we sought to assess SMM risk at the nexus of racial/ethnic marginalization, weathering, and neighborhood/individual socioeconomic disadvantage. We used birth hospitalization records from California across 20 years (1997–2017, N = 9,806,406) on all live births ≥20 weeks gestation. We estimated adjusted average predicted probabilities of SMM at the combination of levels of race/ethnicity, age, and neighborhood deprivation or individual socioeconomic status (SES). The highest risk of SMM was observed among Black birthing people aged ≥35 years who either resided in the most deprived neighborhoods or had the lowest SES. Black birthing people conceptualized to be better off due to their social standing (aged 20–34 years and living in the least deprived neighborhoods or college graduates) had comparable and at times worse risk than White birthing people conceptualized to be worse off (aged ≥35 years and living in the most deprived neighborhoods or had a high-school degree or less). Our findings highlight the need to explicitly address structural racism as the driver of racial/ethnic health inequities and the imperative to incorporate intersectional approaches.

Abstract

Objectives: Among childbearing women, insurance coverage determines degree of access to preventive and emergency care for maternal and infant health. Maternal-infant dyads with dual burden of severe maternal morbidity and preterm birth experience high physical and psychological morbidity, and the risk of dual burden varies by insurance type. We examined whether sociodemographic and perinatal risk factors of dual burden differed by insurance type. Methods: We estimated relative risks of dual burden by maternal sociodemographic and perinatal characteristics in the 2007–2012 California birth cohort dataset stratified by insurance type and compared effects across insurance types using Wald Z-statistics. Results: Dual burden ranged from 0.36% of privately insured births to 0.41% of uninsured births. Obstetric comorbidities, multiple gestation, parity, and birth mode conferred the largest risks across all insurance types, but effect magnitude differed. The adjusted relative risk of dual burden associated with preeclampsia superimposed on preexisting hypertension ranged from 9.1 (95% CI 7.6–10.9) for privately insured to 15.9 (95% CI 9.1–27.6) among uninsured. The adjusted relative risk of dual burden associated with cesarean birth ranged from 3.1 (95% CI 2.7–3.5) for women with Medi-Cal to 5.4 (95% CI 3.5–8.2) for women with other insurance among primiparas, and 7.0 (95% CI 6.0–8.3) to 19.4 (95% CI 10.3–36.3), respectively, among multiparas. Conclusions: Risk factors of dual burden differed by insurance type across sociodemographic and perinatal factors, suggesting that care quality may differ by insurance type. Attention to peripartum care access and care quality provided by insurance type is needed to improve maternal and neonatal health.

Abstract

Perinatal illicit substance use is a nursing and public health issue. Current screening policies have significant consequences for birthing individuals and their families. Racial disparities exist in spite of targeted and universal screening policies and practices. Thus, new theoretical approaches are needed to investigate perinatal illicit substance use screening in hospital settings. The purpose of this analysis is to evaluate the social construction of target populations theory in the context of perinatal illicit substance use screening. Using the theoretical insights of this theory to interrogate the approaches taken by policy makers to address perinatal illicit substance use and screening provides the contextual framework needed to understand why specific policy tools were selected when designing public policy to address these issues. The analysis and evaluation of this theory was conducted using the theory description and critical reflection model.

Abstract

Objective: To solicit advice from members of the Association of Women's Health, Obstetric, and Neonatal Nurses (AWHONN) on what to include in an update of nurse staffing standards. Design: Online, single-question survey with thematic analysis of responses. Setting: Electronic survey link sent via e-mail. Participants: AWHONN members who shared their e-mail with the association and who responded to the survey (n = 1,813). Measures: Participants were asked to answer this single question: “The AWHONN (2010) Guidelines for Professional Registered Nurse Staffing for Perinatal Units are being updated. During their initial development, feedback from nearly 900 AWHONN members was extremely helpful in providing specific details for the nurse staffing guidelines. We'd really like to hear from you again. Please give the writing team your input. What should AWHONN consider when updating the AWHONN nurse staffing guidelines?” Results: The e-mail was successfully delivered to 20,463 members; 8,050 opened the e-mail, and 3,050 opened the link to the survey. There were 1,892 responses. After removing duplicate and blank responses, 1,813 responses were available for analysis. They represented all hospital practice settings for maternity and newborn care and included nurses from small-volume and rural hospitals. Primary concerns of respondents centered on two aspects of patient acuity—the increasing complexity of clinical cases and the need to link nurse staffing standards to patient acuity. Other themes included maintaining current nurse-to-patient ratios, needing help with implementation in the context of economic challenges, and changing wording from “guidelines” to “standards” to promote widespread adoption. Conclusion: In a single-question survey, AWHONN members offered rich, detailed recommendations that were used in the updating of the AWHONN nurse staffing standards.

Abstract

Objective Communication failures between clinicians lead to poor patient outcomes. Critically injured patients have multiple injured organ systems and require complex multidisciplinary care from a wide range of healthcare professionals and communication failures are abundantly common. This study sought to determine barriers and facilitators to interdisciplinary communication between the consulting trauma, intensive care unit (ICU) team and specialty consultants for critically injured patients at an urban, safety-net, level 1 trauma centre. Design An observational qualitative study of barriers and facilitators to interdisciplinary communication. Setting We conducted observations of daily rounds in two trauma surgical ICUs and recorded the most frequently consulted teams. Participants Key informant interviews after presenting clinical vignettes as discussion prompts were conducted with a broad range of clinicians from the ICUs and physicians and nurse practitioners from the consultant teams who were identified during the observations. Interviews were recorded and transcribed verbatim. Data of these 10 interviews were combined with primary transcript data from prior study (25 interviews) and analysed together because of the same setting with same themes. Independent coding of the transcripts, with iterative reconciliation, was performed by two coders. Outcomes measures Facilitators and barriers of interdisciplinary communication were identified. Results A total of 35 interview transcripts were analysed. Cardiology and interventional radiology were the most frequently consulted teams. Consulting and consultant clinicians reported that perceived accessibility from the team seeking a consultation and the consultant team impacted interdisciplinary communication. Accessibility had a physical dimension as well as a psychological dimension. Accessibility was demonstrated by responsiveness between clinicians of different disciplines and in turn facilitated interdisciplinary communication. Social norms, cognitive biases, hierarchy and relationships were reported as both facilitators and barriers to accessibility, and therefore, interdisciplinary communication. Conclusion Accessibility impacted interdisciplinary communication between the consulting and the consultant team. Article summary Elucidates barriers and facilitators to interdisciplinary communication between consulting and consultant teams.

Abstract

Purpose:The objective of this study was to examine the current state of literature on group prenatal care and its impact on maternal outcomes and racial disparities in adverse maternal outcomes.Design:We conducted a scoping review of literature published between January 2010 and December 2020 using the PRISMA-ScR reporting checklist.Methods:Eligible studies were identified using key words and MeSH terms in PubMed, CINAHL, and Web of Science. Inclusion criteria were studies that were (a) conducted in the United States; (b) published between January 2010 and December 2020; (c) in English; (d) focused on the primary investigation of group prenatal care and reporting on maternal comorbidity outcomes; and (e) an observational study or clinical trial.Results:Nine studies met inclusion criteria. They reported on outcomes of preeclampsia, gestational hypertension, gestational diabetes mellitus, final A1C among patients with gestational diabetes mellitus, and postpartum hemorrhage. None reported on racial disparities for minoritized populations. Among all reported maternal outcomes, results were mixed, providing inconclusive evidence.Clinical Implications:Outcomes from group prenatal care focus more on neonatal outcomes than maternal outcomes. More studies are needed with stronger designs. Given pervasive racial disparities in U.S. maternal mortality, future studies should assess how group prenatal care participation may contribute to fewer experiences of racial discrimination and implicit bias for Black women in maternity care.

Abstract

Importance: Complications during pregnancy and birth can impact whether an individual has more children. Individuals experiencing SMM are at a higher risk of general and reproductive health issues after pregnancy, which could reduce the probability of a subsequent birth. Objective: To examine whether experiencing SMM during an individual's first birth affects their probability of having an additional birth, and whether this effect varies by maternal factors. Methods: This retrospective cohort study US linked vital records and maternal discharges from 1997 to 2017 to identify all California births. The exposure, Severe Maternal Morbidity (SMM) was identified using a Centers for Disease Control and Prevention index. Individuals whose first birth was a singleton live birth were followed until their second birth or December 31, 2017, whichever came first. Hazard ratios for having a subsequent birth were estimated using Cox proportional hazard regression models. This association was assessed overall and stratified by maternal factors of a priori interest: age, race/ethnicity, and payer. Results: Of the 3,916,413 individuals in our study, 51,872 (1.3%) experienced SMM at first birth. Compared to those who do not experience SMM, individuals who had SMM had a lower hazard, or instantaneous rate, of subsequent birth (adjusted HR 0.83, 95% CI: 0.82, 0.84); this association was observed in all levels of stratification (for example, adjusted HR range for known race/ethnicity: 0.78, 95% CI: 0.76, 0.80 for non-Hispanic White to 0.90, 95% CI: 0.88, 0.92 for Hispanic) and all indicators of SMM (0.24, 95% CI: 0.17, 0.35 for cardiac arrest/ventricular fibrillation to 0.84, 95% CI: 0.80, 0.87 for eclampsia). Conclusion and Relevance: Our findings suggest that individuals who experience SMM at the time of their first birth are less likely to have a subsequent birth as compared to those who do not experience SMM at the time of their first birth. While the reasons for these findings are unclear, they could inform reproductive life planning discussions for individuals experiencing SMM. Future directions include studies exploring the reasons for not having a subsequent birth.

Abstract

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

Abstract

Over a decade following the nationwide push to implement electronic health records (EHRs), the focus has shifted to addressing the cognitive burden associated with their use. Most research and discourse about the EHR's impact on clinicians' cognitive work has focused on physicians rather than on nursing-specific issues. Labor and delivery nurses may encounter unique challenges when using EHRs because they also interact with an electronic fetal monitoring system, continuously managing and synthesizing both maternal and fetal data. This grounded theory study explored labor and delivery nurses' perceptions of the EHR's impact on their cognitive work. Data were individual interviews and participant observations with twenty-one nurses from two labor and delivery units in the western U.S. and were analyzed using dimensional analysis. Nurses managed the tension between caring and charting using various strategies to integrate the EHR into their dynamic, high-acuity, specialty practice environment while using EHRs that were not designed for perinatal patients. Use of the EHR and associated technologies disrupted nurses' ability to locate and synthesize information, maintain an overview of the patient's status, and connect with patients and families. Individual-, group-, and environmental-level factors facilitated or constrained nurses' integration of the EHR. These findings represent critical safety failures requiring comprehensive changes to EHR designs and better processes for responding to end-user experiences. More research is needed to develop EHRs that support the dynamic and relationship-based nature of nurses' work and to align with specialty practice environments.

Abstract

Background: Prior studies have documented associations between preterm birth and severe maternal morbidity (SMM) but the prevalence and correlates of dual burden are not adequately understood, despite significant family implications. Purpose: To describe the prevalence and correlates of the dual burden of SMM and preterm birth and to understand profiles of SMM by dual burden of preterm birth. Approach: This retrospective cohort study included all California live births in 2007-2012 with gestations 20-44 weeks and linked to a birth cohort database maintained by the California Office of Statewide Health Planning and Development (n = 3,059,156). Dual burden was defined as preterm birth (<37 weeks) with severe maternal morbidity (SMM, defined by Centers for Disease Control). Predictors for dual burden were assessed using Poisson logistic regression, accounting for hospital variance. Results: Rates of preterm birth and SMM were 876 and 140 per 10,000 births, respectively. The most common indications of SMM both with and without preterm birth were blood transfusions and a combination of cardiac indications. One-quarter of women with SMM experienced preterm birth with a dual burden rate of 37 per 10,000 births. Risk of dual burden was over threefold higher with cesarean birth (primiparous primary aRR = 3.3, CI = 3.0-3.6; multiparous primary aRR = 8.1, CI = 7.2-9.1; repeat aRR = 3.9, CI = 3.5-4.3). Multiple gestation conferred a six-fold increased risk (aRR = 6.3, CI = 5.8-6.9). Women with preeclampsia superimposed on gestational hypertension (aRR = 7.3, CI = 6.8-7.9) or preexisting hypertension (aRR = 11.1, CI = 9.9-12.5) had significantly higher dual burden risk. Significant independent predictors for dual burden included smoking during pregnancy (aRR = 1.5, CI = 1.4-1.7), preexisting hypertension without preeclampsia (aRR = 3.3, CI = 3.0-3.7), preexisting diabetes (aRR = 2.6, CI = 2.3-3.0), Black race/ethnicity (aRR = 2.0, CI = 1.8-2.2), and prepregnancy body mass index <18.5 (aRR = 1.4, CI = 1.3-1.5). Conclusions: Dual burden affects 1900 California families annually. The strongest predictors of dual burden were hypertensive disorders with preeclampsia and multiparous primary cesarean.
