Participant Perspectives on the Implementation of a School-Linked Text-Message Intervention to Improve Pediatric Asthma Medication Adherence.

Background: Poor adherence to inhaled corticosteroids (ICS) is a significant challenge in pediatric asthma, contributing to health inequities. Text-message reminders for ICS therapy are an evidence-based approach that improves pediatric asthma medication adherence, yet has not been widely adopted into practice, partly due to lack of (1) participant input on design and implementation and (2) use of sustainable community linkages. Remote Asthma Link™ (RAL) seeks to fill this gap as a school-linked text-message intervention wherein parents of children with poorly controlled asthma received daily, 2-way text-message reminders for preventive inhaler use. Responses were shared with school nurses who conducted remote check-ins with families. Enrolled children, largely from underserved backgrounds, experienced improvements in medication adherence and asthma health outcomes. While initial results were promising, we have yet to elicit participant input to refine the protocol for more widespread implementation. Objective: Examine participant perspectives on barriers and facilitators of RAL implementation. Methods: Semistructured interviews were conducted May-June 2022 with intervention participants: 10 parents, 7 school nurses, and 4 pediatric providers (n = 21) until thematic saturation was reached. Interview transcripts were coded using thematic analysis. Results: Several facilitators for RAL implementation were identified, including ease of use and accessibility, personal connection to the school nurse, and receipt of a visual notification for habit formation. Barriers included challenges with school nurses reaching parents, poor understanding of program expectations, and lack of reimbursement structure. Participant-proposed solutions to barriers included utilizing alternate communication methods (eg, social media), educational sessions, and meeting with payors to consider reimbursement models. Conclusion: RAL is a school-linked text-message intervention demonstrating promise in improving outcomes and equity in asthma care. Key implementation facilitators, barriers, and proposed solutions will inform protocol adaptations to promote successful implementation of this and other text-message interventions into clinical practice.

Quality of Care for Latinx Children with Asthma: Associations with Language Concordance and Continuity of Care.

BACKGROUND: Language concordance between Latinx patients and their clinicians has been shown to affect health outcomes. In addition, there is evidence that consistent continuity of care (COC) can improve health care outcomes. The relationship between language concordance and COC and their association with health equity in chronic disease is less clear. Our aim was to study the moderating effect of clinician and patient language concordance on the association between COC and asthma care quality in Latinx children. METHODS: We utilized an electronic health record dataset from a multistate network of community health centers to compare influenza vaccinations and inhaled steroid prescriptions, by ethnicity and language concordance groups overall and stratified by COC. RESULTS: We analyzed electronic health records for children with asthma (n = 38,442) age 3 to 17 years with ≥2 office visits between 2005 to 2017. Overall, 64% of children had low COC (defined as COC < 0.5) while 21% had high COC (defined as >0.75). All Latinx children had higher rates and odds of receiving influenza vaccination compared with non-Hispanic White children. In addition, Spanish-preferring Latinx children had higher rates and odds of being prescribed inhaled steroids while English-preferring Latinx children had lower odds (OR = 0.85 95%CI = 0.73,0.98) compared with non-Hispanic White children. CONCLUSION: Overall, Latinx children regardless of COC category or language concordance were more likely to receive the influenza vaccine. English-preferring Latinx children with persistent asthma received fewer inhaled steroid prescriptions compared with non-Hispanic White children. Panel chart review and seeing a practice partner might be one way to combat these inequities.

School-supervised Asthma Therapy is Associated with Improved Long-Term Asthma Outcomes for Underrepresented Minority Children.

Asthma morbidity disproportionately impacts children from low-income and racial/ethnic minority communities. School-supervised asthma therapy improves asthma outcomes for up to 15 months for underrepresented minority children, but little is known about whether these benefits are sustained over time. We examined the frequency of emergency department (ED) visits and hospital admissions for 83 children enrolled in Asthma Link, a school nurse-supervised asthma therapy program serving predominantly underrepresented minority children. We compared outcomes between the year preceding enrollment and years one-four post-enrollment. Compared with the year prior to enrollment, asthma-related ED visits decreased by 67.9% at one year, 59.5% at two years, 70.2% at three years, and 50% at four years post-enrollment (all p-values< 0.005). There were also significant declines in mean numbers of total ED visits, asthma-related hospital admissions, and total hospital admissions. Our results indicate that school nurse-supervised asthma therapy could potentially mitigate racial/ethnic and socioeconomic inequities in childhood asthma.

Folic Acid in Pregnancy and Childhood Asthma: A US Cohort.

Prenatal folic acid exposure has been linked to higher risk of childhood asthma in countries that do not fortify the food supply with folic acid. This study seeks to examine this association in the United States, where the food supply is generally fortified with folic acid. Participants were 1279 mother-child pairs from Project Viva, an ongoing prospective birth cohort, with folic acid intake in pregnancy assessed through validated food frequency questionnaires. The primary outcome was physician-diagnosed asthma at mid-childhood. In an unadjusted logistic regression model, higher folic acid intake was associated with lower odds of asthma in mid-childhood (odds ratio [OR] 0.48; 95% CI 0.31-0.76). However, in the adjusted analysis this association was attenuated (adjusted OR [aOR] 0.80; 95% CI 0.49-1.33). Our results suggest that in the United States, where there is generalized folic acid fortification of food, maternal folic acid intake during pregnancy is not associated with asthma development in offspring.

Synbiotics for Prevention and Treatment of Atopic Dermatitis: A Meta-analysis of Randomized Clinical Trials.

IMPORTANCE: Atopic dermatitis (AD) is a highly prevalent condition that may be associated with an altered gastrointestinal microbiota that promotes an immune environment more susceptible to allergic disease. Synbiotics, a mixture of prebiotics and probiotics, have been used for the prevention and treatment of AD. OBJECTIVE: To investigate the efficacy of synbiotics for primary prevention and treatment of AD. DATA SOURCES: PubMed/MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials, and the CAB Abstracts Archive searchable database were searched from the inception of all databases to October 15, 2015, with no language restrictions. STUDY SELECTION: We included all published randomized clinical trials of synbiotics for prevention and/or treatment of AD. To be included, a publication needed to clearly define the intervention as oral administration of synbiotics (combination of probiotics and prebiotics) and must have included an assessment of AD disease severity, such as the Severity Scoring of Atopic Dermatitis (SCORAD) index, or the incidence of AD as an outcome measure. Only 8 of 257 initially identified studies (3%) met selection criteria. DATA EXTRACTION AND SYNTHESIS: Data extraction was independently done by multiple observers and cross-checked to avoid errors. The quality of the selected studies was critically examined following the Cochrane guidelines. Data were pooled using a random-effects model. MAIN OUTCOMES AND MEASURES: The primary outcomes were the SCORAD index (treatment studies) and the relative risk of AD (prevention studies). The hypothesis was formulated before data collection. RESULTS: A total of 257 abstracts were screened to identify 6 treatment studies (369 children enrolled; aged 0 months to 14 years) and 2 prevention studies (1320 children enrolled; up to age 6 months in one study and term neonates aged <3 days in the other). From the 6 treatment studies included for random-effects meta-analysis, the overall pooled change in SCORAD index in those treated with synbiotics at 8 weeks of treatment was -6.56 (95% CI, -11.43 to -1.68; P = .008). Heterogeneity was significant (I(2) = 77.1%; P = .001). Subgroup analysis showed that the beneficial effect was significant only when using mixed strains of bacteria (weighted mean difference, -7.32; 95% CI, -13.98 to -0.66; P = .03) and when used in children aged 1 year or older (weighted mean difference, -7.37; 95% CI, -14.66 to -0.07; P = .048). From the 2 prevention studies included, the pooled relative risk ratio of AD in those treated with synbiotics compared with placebo was 0.44 (95% CI, 0.11 to 1.83; P = .26). CONCLUSIONS AND RELEVANCE: This meta-analysis shows evidence that supports the use of synbiotics for the treatment of AD, particularly synbiotics with mixed strains of bacteria and for children aged 1 year or older. Further studies are needed to evaluate the effectiveness of synbiotics for primary prevention of AD.
