Audrey Lyndon's additional information

Dr. Lyndon is the Vernice D. Ferguson Professor in Health Equity and assistant dean for clinical research at NYU Rory Meyers College of Nursing. Her equity work is focused in two areas: maternal health equity and diversifying the nursing science and healthcare workforce. Dr. Lyndon’s maternal health work has focused on patient safety and quality in maternity and neonatal care, including improving communication and teamwork among clinicians; identifying parents’ perspectives on safety during labor, birth, and neonatal care; developing nurse-sensitive outcomes for labor and birth; and research on severe maternal morbidity and maternal mortality. Her team has conducted groundbreaking research on differences in clinicians’ and parents’ perspective on speaking up about safety concerns and developing an understanding of how women and parents conceptualize safety during childbirth and neonatal intensive care. Dr. Lyndon co-chaired the development of the CMQCC Obstetric Hemorrhage Toolkit, which became a national and international model for maternal safety bundles and collaborative quality improvement. Dr. Lyndon recently completed a study funded by the Agency for Healthcare Research and Quality examining relationships between nursing care during labor and patient outcomes. She is currently focused on understanding the experiences of Black and Latinx survivors of severe maternal morbidity to better identify their support needs, research priorities, and community-driven prevention targets for severe maternal morbidity. Dr. Lyndon’s work on diversifying the nursing science and healthcare workforce includes mentoring and sponsorship of historically excluded clinicians and scientists and efforts to build effective pathways programs for historically excluded individuals into nursing, nursing science, and clinical specialties.

Use of Galactagogues to Increase Milk Production Among Breastfeeding Mothers in the United States: A Descriptive Study

Ryan, R. A., Hepworth, A. D., Lyndon, A., & Bihuniak, J. D. (2023). Journal of the Academy of Nutrition and Dietetics, 123(9), 1329-1339. 10.1016/j.jand.2023.05.019
Abstract
Abstract
Background: Perceived insufficient milk is a primary reason for early breastfeeding cessation. Some breastfeeding mothers may use galactagogues (ie, foods, beverages, herbal supplements, and pharmaceuticals) to try to increase milk supply. However, milk production requires frequent and effective milk removal, and there is limited evidence on the safety and efficacy of galactagogues. Additional research on the use of galactagogues is needed to inform breastfeeding support. Objective: Describe the prevalence of use and perceived effects of galactagogues and compare galactagogue use by maternal characteristics. Design: Cross-sectional online survey. Participants/setting: A convenience sample of 1,294 adult women breastfeeding a singleton child and living in the United States were recruited using paid Facebook advertisements between December 2020 and February 2021. Main outcome measures: Self-reported current or previous use of galactagogues and their perceived effects on milk production. Statistical analyses performed: Frequencies and percentages described the use and perceived effects of galactagogues. The χ2 test of independence and independent t tests compared galactagogue use by select maternal characteristics. Results: More than half of participants (57.5%) reported using any galactagogues, 55.4% reported consuming foods or beverages, and 27.7% reported using herbal supplements. Few participants (1.4%) reported using pharmaceuticals. Participants reported varying effects of specific galactagogues on milk production. Reported galactagogue use was higher among participants who reported first-time breastfeeding (yes: 66.7% vs no: 49.3%; P < 0.001), breastfeeding pumped milk (yes: 63.1% vs no: 50.4%; P < 0.001), formula supplementation (yes: 66.8% vs no: 50.4%; P < 0.001), and perceived insufficient milk (yes: 78.8% vs no: 53.8%; P < 0.001). Conclusions: Breastfeeding mothers in the United States commonly reported using galactagogues to increase milk production, highlighting the need for research on the safety and efficacy of galactagogues and enhanced breastfeeding support.

Using medical expenditure panel survey data to explore the relationship between patient-centered medical homes and racial disparities in severe maternal morbidity outcomes

Tucker, C. M., Bell, N., Corbett, C. F., Lyndon, A., & Felder, T. M. (2023). Women’s Health, 19. 10.1177/17455057221147380
Abstract
Abstract
Background: There are persistent racial/ethnic disparities in the occurrence of severe maternal morbidity. Patient-centered medical home care has the potential to address disparities in maternal outcomes. Objectives: To examine (1) the association between receiving patient-centered medical home care and severe maternal morbidity outcomes and (2) the interaction of race/ethnicity on patient-centered medical home status and severe maternal morbidity. Design/Methods: Using 2007 to 2016 data from the Medical Expenditures Panel Survey, we conducted a cross-sectional study to estimate the association between receipt of care from a patient-centered medical home and the occurrence of severe maternal morbidity, and racial-specific (White, Black, Asian, Other) relative risks of severe maternal morbidity. Our study used race as a proxy measure for exposure racism. We identified mothers (⩾15 years) who gave birth during the study period. We identified patient-centered medical home qualities using 11 Medical Expenditures Panel Survey questions and severe maternal morbidities using medical claims, and calculated generalized estimating equation models to estimate odds ratios of severe maternal morbidity and 95% confidence intervals. Results: Among all mothers who gave birth (N = 2801; representing 5,362,782 US lives), only 25% received some exposure patient-centered medical home care. Two percent experienced severe maternal morbidity, and this did not differ statistically (p = 0.11) by patient-centered medical home status. However, our findings suggest a 85% decrease in the risk of severe maternal morbidity among mothers who were defined as always attending a patient-centered medical home (odds ratios: 0.15; 95% confidence interval:0.01–1.87; p = 0.14) and no difference in the risk of severe maternal morbidity among mothers who were defined as sometimes attending a patient-centered medical home (odds ratios: 1.00; 95% confidence interval:0.16–6.42; p = 1.00). There was no overall interaction effect in the model between race and patient-centered medical home groups (p = 0.82), or ethnicity and patient-centered medical home groups (p = 0.62) on the severe maternal morbidity outcome. Conclusion: While the rate of severe maternal morbidity was similar to US rates, few mothers received care from a patient-centered medical home which may be due to underreporting. Future research should further investigate the potential for patient-centered medical home-based care to reduce odds of severe maternal morbidity across racial/ethnic groups.

Antidepressant use During Pregnancy: Knowledge, Attitudes, and Decision-Making of Patients and Providers

Eakley, R., & Lyndon, A. (2022). Journal of Midwifery and Women’s Health, 67(3), 332-353. 10.1111/jmwh.13366
Abstract
Abstract
Introduction: Despite the risks associated with untreated perinatal depression and anxiety, both patients and clinicians are less likely to follow evidence-based guidelines including the use of antidepressants during pregnancy. The aim of this integrative review was to describe the perspectives of both patients and prescribing health care providers regarding the use of antidepressants during pregnancy. Methods: We performed a literature search in PubMed, CINAHL, ProQuest Central, and PsychINFO. Inclusion criteria were English language, original peer-reviewed research published within the previous 10 years that described perspectives regarding the use of antidepressants of pregnant patients or prescribing providers during pregnancy. Studies were excluded if their focus was on screening practices, treatment guidelines, or evaluation of decision support tool; medication or treatment broadly; bipolar disorder or serious mental illness; or they did not provide patient or provider perspective. This review was limited to professionals with scopes of practice that include prescriptive authority (eg, physicians, advanced practices nurses, midwives). Included articles were critically appraised and read in an iterative process to extract methodological details and synthesize findings. Results: Nineteen studies met criteria for inclusion and varied by design, sample, and quality. Together, the reviewed articles suggest that patients and prescribing providers hold a range of beliefs regarding the safety of antidepressant during pregnancy. Patients and providers appear to value different sources of information and varied in awareness of the negative impacts of untreated depression and anxiety during pregnancy. Many patients report dissatisfaction with available information and distress throughout the decision-making experience. Notably, patients and providers had incongruent perceptions of the others’ experience. Discussion: Inconsistencies between knowledge, attitudes, and decision-making highlight the need for improved dissemination of evidence-based treatments and support increased training for psychopharmacology during pregnancy. Efforts to reduce patient distress regarding their decisions, such as adequate time and information, are indicated.

Nurse-Reported Staffing Guidelines and Exclusive Breast Milk Feeding

Lyndon, A., Simpson, K. R., Spetz, J., Zhong, J., Gay, C. L., Fletcher, J., & Landstrom, G. L. (2022). Nursing Research, 71(6), 432-440. 10.1097/NNR.0000000000000620
Abstract
Abstract
Background Nursing care is essential to overall quality of healthcare experienced by patients and families - especially during childbearing. However, evidence regarding quality of nursing care during labor and birth is lacking, and established nurse-sensitive outcome indicators have limited applicability to maternity care. Nurse-sensitive outcomes need to be established for maternity care, and prior research suggests that the initiation of human milk feeding during childbirth hospitalization is a potentially nurse-sensitive outcome. Objective The aim of this study was to determine the relationship between nurse-reported staffing, missed nursing care during labor and birth, and exclusive breast milk feeding during childbirth hospitalization as a nurse-sensitive outcome. Methods 2018 Joint Commission PC-05 Exclusive Breast Milk Feeding rates were linked to survey data from labor nurses who worked in a selected sample of hospitals with both PC-05 data and valid 2018 American Hospital Association Annual Survey data. Nurse-reported staffing was measured as the perceived compliance with Association of Women's Health, Obstetric and Neonatal Nurses staffing guidelines by the labor and delivery unit. Data from the nurse survey were aggregated to the hospital level. Bivariate linear regression was used to determine associations between nurse and hospital characteristics and exclusive breast milk feeding rates. Generalized structural equation modeling was used to model relationships between nurse-reported staffing, nurse-reported missed care, and exclusive breast milk feeding at the hospital level. Results The sample included 184 hospitals in 29 states and 2,691 labor nurses who worked day, night, or evening shifts. Bivariate analyses demonstrated a positive association between nurse-reported staffing and exclusive breast milk feeding and a negative association between missed nursing care and exclusive breast milk feeding. In structural equation models controlling for covariates, missed skin-to-skin mother-baby care and missed breastfeeding within 1 hour of birth mediated the relationship between nurse-reported staffing and exclusive breast milk feeding rates. Discussion This study provides evidence that hospitals' nurse-reported compliance with Association of Women's Health, Obstetric and Neonatal Nurses staffing guidelines predicts hospital-exclusive breast milk feeding rates and that the rates are a nurse-sensitive outcome.

Racial/ethnic disparities in severe maternal morbidity: An intersectional lifecourse approach

Hailu, E. M., Carmichael, S. L., Berkowitz, R. L., Snowden, J. M., Lyndon, A., Main, E., & Mujahid, M. S. (2022). Annals of the New York Academy of Sciences, 1518(1), 239-248. 10.1111/nyas.14901
Abstract
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.

Risk Factors for Dual Burden of Severe Maternal Morbidity and Preterm Birth by Insurance Type in California

El Ayadi, A. M., Baer, R. J., Gay, C., Lee, H. C., Obedin-Maliver, J., Jelliffe-Pawlowski, L., & Lyndon, A. (2022). Maternal and Child Health Journal, 26(3), 601-613. 10.1007/s10995-021-03313-1
Abstract
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.

Social Construction of Target Populations: A Theoretical Framework for Understanding Policy Approaches to Perinatal Illicit Substance Screening

Cooper, N. M., Lyndon, A., McLemore, M. R., & Asiodu, I. V. (2022). Policy, Politics, and Nursing Practice, 23(1), 56-66. 10.1177/15271544211067781
Abstract
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.

AWHONN Members’ Recommendations on What to Include in Updated Standards for Professional Registered Nurse Staffing for Perinatal Units

Simpson, K. R., Roth, C. K., Hering, S. L., Landstrom, G. L., Lyndon, A., Tinsley, J. M., Zimmerman, J., & Hill, C. M. (2021). Nursing for Women’s Health, 25(5), 329-336. 10.1016/j.nwh.2021.08.001
Abstract
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.

Barriers and facilitators to interdisciplinary communication during consultations: A qualitative study

Liu, P., Lyndon, A., Holl, J. L., Johnson, J., Bilimoria, K. Y., & Stey, A. M. (2021). BMJ Open, 11(9). 10.1136/bmjopen-2020-046111
Abstract
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.
