Objective: To qualitatively explore Medicaid-enrolled parents’ and young adult patients’ perspectives and experiences with telemedicine in pediatric primary care. Methods: We conducted semi-structured interviews with participants to explore their experiences with telemedicine. Participants consisted of English- and Spanish-speaking parents and young adults (18–21) who engaged in a telemedicine visit between March 15, 2021 and December 31, 2022 at two pediatric primary care clinics whose patients are predominantly insured by Medicaid. A qualitative descriptive design was used to develop a taxonomy. Frequencies were obtained to identify the most prevalent themes. Results: Twenty-six participants (22 parents, 4 young adults) were interviewed. Twelve (46%) participants were English-speaking and 14 (53%) were Spanish-speaking. Four domains were identified, each further classified into themes: pre-visit expectations (option for in-person visit, general anticipation, and specific worries), visit experience (general sentiment, technology, and quality of care), comfort (with overall process, privacy, and communication), and feelings about telemedicine (advantages, disadvantages, and loss of telemedicine). Although many participants had negative expectations of telemedicine prior to their appointment, a majority indicated positive experiences with visits and concerns about a possible future where telemedicine visits at home were no longer covered by their health insurance. Discussion: Most participants indicated positive experiences with telemedicine and perceived negative impact if access was removed. Findings related to perceived quality of care, advantages, and disadvantages suggest that patient preferences and individual circumstances should be taken into account when choosing visit modality in similar settings.

Background Immigrant Latinas (who are foreign-born but now reside in the USA) are at greater risk for developing postpartum depression than the general perinatal population, but many face barriers to treatment. To address these barriers, we adapted the Mothers and Babies Course—an evidence-based intervention for postpartum depression prevention—to a virtual group format. Additional adaptations are inclusion of tailored supplemental child health content and nutrition benefit assistance. We are partnering with Early Learning Centers (ELC) across the state of Maryland to deliver and test the adapted intervention. Methods The design is a Hybrid Type I Effectiveness-Implementation Trial. A total of 300 participants will be individually randomized to immediate (N = 150) versus delayed (N = 150) receipt of the intervention, Mothers and Babies Virtual Group (MB-VG). The intervention will be delivered by trained Early Learning Center staff. The primary outcomes are depressive symptoms (measured via the Center for Epidemiologic Studies-Depression Scale), parenting self-efficacy (measured via the Parental Cognition and Conduct Towards the Infant Scale (PACOTIS) Parenting Self-Efficacy subscale), and parenting responsiveness (measured via the Maternal Infant Responsiveness Instrument) at 1-week, 3-month, and 6-month post-intervention. Depressive episodes (Structured Clinical Interview for DSM-V- Disorders Research Version) at 3-month and 6-month post-intervention will also be assessed. Secondary outcomes include social support, mood management, anxiety symptoms, perceived stress, food insecurity, and mental health stigma at 1-week, 3-month, and 6-month post-intervention. Exploratory child outcomes are dysregulation and school readiness at 6-month post-intervention. Intervention fidelity, feasibility, acceptability, and appropriateness will also be assessed guided by the Reach, Effectiveness, Adoption, Implementation, Maintenance (RE-AIM) framework. Discussion This study will be one of the first to test the efficacy of a group-based virtual perinatal depression intervention with Latina immigrants, for whom stark disparities exist in access to health services. The hybrid effectiveness-implementation design will allow rigorous examination of barriers and facilitators to delivery of the intervention package (including supplemental components) which will provide important information on factors influencing intervention effectiveness and the scalability of intervention components in Early Learning Centers and other child-serving settings.

Objective: To compare telemedicine versus office visit use at two Medicaid-focused pediatric primary care clinics. Methods: Retrospective cohort study from March 15, 2020 - March 15, 2021 at two Medicaid-focused pediatric primary care clinics. Site A and Site B care for different populations (Site B care for mostly immigrant families with preferred language Spanish). Outcomes included the percent of visits conducted through telemedicine and reason for visit. Descriptive statistics, univariable and multivariable mixed multilevel logistic regression, were used to assess relationship between patient demographics and telemedicine use. Results: Out of 17,142 total visits, 13% of encounters at Site A (n = 987) and 25% of encounters at Site B (n = 2,421) were conducted using telemedicine. Around 13.8% of well-child care (n = 1,515/10,997), 36.2% of mental health care (n = 572/1,581), and 25.0% of acute care/follow-up (n = 1,893/7,562) were telemedicine visits. After adjustment for covariates, there was no difference in odds of a patient having any telemedicine use by preferred language, sex, or payor. Patients 1-4 years of age had the lowest odds of telemedicine use. At Site A, patients who identified as Non-Hispanic Black (odds ratio [OR] = 0.33, 95% confidence interval [CI] = 0.24-0.45), Hispanic/Latinx (OR = 0.40, 95% CI = 0.24-0.66), or other race/ethnicity (OR = 0.35, 95% CI = 0.23-0.55) had lower odds of telemedicine use in comparison to Non-Hispanic White. Conclusions: Telemedicine was successfully accessed by Medicaid enrollees for different types of pediatric primary care. There was no difference in telemedicine use by preferred language and payor. However, differences existed by age at both sites and by race/ethnicity at one site. Future research should explore operational factors that improve telemedicine access for marginalized groups.


Culturally Sensitive Interventions for Latinas and Spanish-Speaking Women

Interventions to meet the mental health needs of women suffering from perinatal depression or anxiety are limited, particularly those that are culturally and linguistically appropriate. The development and implementation of culturally sensitive interventions are necessary for increasing treatment engagement and effectiveness, as well as promoting the well-being of perinatal Latinas residing in the United States. Immigrant Latinas are equally susceptible to perinatal mood disorders as other populations and may carry a unique set of psychosocial factors (e.g., immigration status) that raise their risk for developing depressive or anxious symptoms. This chapter will (1) highlight specific interventions that can help meet the growing need for culturally and linguistically appropriate treatment, (2) share foundational insights to support those planning for similar interventions, and (3) recommend practices for developing and adapting interventions for Latinas and Spanish-speaking women. To facilitate this, two case studies developed and adapted as culturally sensitive interventions will be showcased. Additionally, immigrant-related stressors that drive the psychosocial risk factors of migration and how to address them will be discussed.

Background: Implementation of evidence-based interventions to reduce depression among uninsured Latinx patients who are at high risk of depression are rare. Objectives: Our goal was to evaluate Strong Minds, a language and culturally tailored, evidence-based intervention adapted from cognitive behavioral therapy (CBT) for mild-moderate depression and anxiety, delivered by community health workers (CHWs) in Spanish to uninsured Latinx immigrants. Methods: As part of the pilot, 35 participants, recruited from a free community primary care clinic, completed Strong Minds. Assessments and poststudy interviews were conducted. Paired t-tests were used to assess change of depressive symptoms at 3 and 6 months. Lessons learned: CHW delivery of depression care to this population was feasible and among those who completed the program, preliminary evidence of depression outcomes suggests potential benefit. CHWs had specific training and support needs related to mental health care delivery. Conclusions: Further implementation studies of depression care interventions using CHWs for underserved Latinx is needed.

Introduction: Latinx immigrant-origin youth (IOY) have unique risks for suicidal thoughts and behaviors. It has been suggested that these risks should be addressed from an ecological perspective, addressing cultural and family context as well as structural and systemic barriers to prevention. This study sought to explore perspectives of immigrant-origin Latinx adolescents and their caregivers on suicide and its prevention, including the potential impact of stressors specific to immigrant status. Method: Focus groups were conducted in 2018–2019 with Latinx immigrant-origin caregivers (N = 41, 97.5% female) and adolescents (ages = 14–19, N = 56, 50% female). Participants were recruited from community-based organizations in two different cities. A codebook approach to thematic analysis was used to identify themes, which were subsequently mapped onto levels of the Center for Disease Control’s Social-Ecological Framework for Violence Prevention. Results: Participants identified both contributors to suicidal behavior and potential components of prevention programming across ecological levels. Specific recommendations for suicide prevention included engaging in recreation, parenting education and support, enhancing academic supports for adolescents, and enhancing school–family communication. Structural barriers (e.g., caregiver work schedules) to implementing recommendations were described. Discussion: Our results highlight the potential role of access to school and community-based supports as public health-oriented suicide prevention strategies and suggest a need to address barriers faced by immigrant families in accessing these supports alongside addressing barriers to mental health treatment. Policies impacting immigrant families’ financial stability and increasing the availability of recreational and academic opportunities may promote mental health and prevent suicidal thoughts and behavior among IOY.

Background: Immigrant Latinas are at higher risk for postpartum depression (PPD) than the general perinatal population, yet face numerous barriers to accessing mental health services. The goal of this study was to pilot an enhanced, virtual group delivery of a PPD prevention program, Mothers and Babies (MB), among immigrant Latinas engaged in early childhood programming. Methods: Forty-nine Spanish-speaking mothers participated in one of four MB virtual groups, facilitated by trained bilingual staff at affiliated early learning centers. MB was enhanced to also target social determinants of health. A mixed-methods design was used to evaluate MB using participant interviews and pre-post surveys measuring depressive symptoms, parenting distress, and self-efficacy to manage emotions. Results: On average, participants attended 69% of MB virtual sessions and rated group cohesiveness at a 4.6 on a 5-point scale. Paired-samples t tests showed significant reductions in depressive symptoms (Cohen's d = 0.29; p = .03) and parenting distress (Cohen's d = 0.31; p = .02), and improved self-efficacy to manage emotions (Cohen's d = -0.58; p < .001). Participants reported both benefits and drawbacks of the virtual format and provided largely favorable feedback on program enhancements. Conclusions: Results provide initial evidence for the acceptability, feasibility, and effectiveness of an enhanced virtual group PPD prevention program for immigrant Latinas, delivered in partnership with local early learning centers. These findings have important implications for extending the reach of preventive interventions among a population that faces many structural and linguistic barriers to traditional forms of mental health service delivery.

... While CHWs have shown promise in delivering BA in many settings and are emerging as part of the evidence base for increasing access to mental health resources [8], their use in the LEP Latino population has not yet been documented. For example, a recent study by Vazquez and colleagues [29] showed that cognitive behavioral therapy delivered by CHWs among a Spanish-speaking population was feasible and acceptable. They also found reductions in depressive scores for study participants. ...

To ensure HIT is accessible to populations using a LOE, it is vital that healthcare organizations and investigators continue to measure and evaluate portal use, quality, cost, and outcomes for patients using a LOE and caregivers [19]. Additionally, parents lacked familiarity with patient portals and other HIT for personal health information, and that may also contribute to concerns about confidentiality and reliability [4,21]. Efforts to improve digital literacy among patients using a LOE, including familiarity and safety of patient portals, through collaborations with community organizations (e.g., libraries) and linguistically tailored support from community health workers may improve familiarity with and use of patient portals and HIT [19]. ...
