Racial/ethnic differences in pediatric asthma management: the importance of asthma knowledge, symptom assessment, and family-provider collaboration

The Sleep Environment, Napping, and Sleep Outcomes among Urban Children With and Without Asthma

OBJECTIVES

Children with asthma living in U.S. urban neighborhoods experience increased risk for asthma morbidity and poor sleep outcomes. In addition to asthma, environmental factors (e.g. noise, uncomfortable temperature, light exposure) related to urban poverty may disturb children's sleep. This study examined the association between environmental factors and sleep outcomes among urban children with and without asthma, and whether napping underlies the environment-sleep link. Additionally, the study tested whether these associations differed by health status (i.e. asthma) or race/ethnicity.

METHOD

Participants included urban children aged 7-9 years with (N = 251) and without (N = 130) asthma from Latino, Black, or non-Latino White (NLW) background. Caregivers reported sleep environmental factors and naps. Sleep duration, efficiency, and nightly awakenings were assessed via actigraphy.

RESULTS

Regardless of health status, frequent exposure to noise and light was associated with poorer sleep outcomes only among Latino children. In the full sample with and without asthma, noise exposure during nighttime sleep was related to more frequent daytime naps, which were linked to shorter nighttime sleep duration.

CONCLUSIONS

Exposure to noise and light may play a particularly influential role in shaping urban children's sleep outcomes. Racial/ethnic differences and the potential mediating role of napping in this environment-sleep association may inform tailored interventions.

Socioeconomic differences in antibiotic use for common infections in pediatric urgent-care centers-A quasi-experimental study

OBJECTIVE

To investigate differences in the rate of firstline antibiotic prescribing for common pediatric infections in relation to different socioeconomic statuses and the impact of an antimicrobial stewardship program (ASP) in pediatric urgent-care clinics (PUCs).

DESIGN

Quasi-experimental.

SETTING

Three PUCs within a Midwestern pediatric academic center.

PATIENTS AND PARTICIPANTS

Patients aged >60 days and <18 years with acute otitis media, group A streptococcal pharyngitis, community-acquired pneumonia, urinary tract infection, or skin and soft-tissue infections who received systemic antibiotics between July 2017 and December 2020. We excluded patients who were transferred, admitted, or had a concomitant diagnosis requiring systemic antibiotics.

INTERVENTION

We used national guidelines to determine the appropriateness of antibiotic choice in 2 periods: prior to (July 2017-July 2018) and following ASP implementation (August 2018-December 2020). We used multivariable regression analysis to determine the odds ratios of appropriate firstline agent by age, sex, race and ethnicity, language, and insurance type.

RESULTS

The study included 34,603 encounters. Prior to ASP implementation in August 2018, female patients, Black non-Hispanic children, those >2 years of age, and those who self-paid had higher odds of receiving recommended firstline antibiotics for all diagnoses compared to male patients, children of other races and ethnicities, other ages, and other insurance types, respectively. Although improvements in prescribing occurred after implementation of our ASP, the difference within the socioeconomic subsets persisted.

CONCLUSIONS

We observed socioeconomic differences in firstline antibiotic prescribing for common pediatric infections in the PUCs setting despite implementation of an ASP. Antimicrobial stewardship leaders should consider drivers of these differences when developing improvement initiatives.

Design of a community-based, Hybrid Type II effectiveness-implementation asthma intervention study: The Rhode Island Asthma Integrated Response (RI-AIR) program

BACKGROUND

Pediatric asthma is among the most common health conditions and disproportionately impacts Black and Latino children. Gaps in asthma care exist and may contribute to racial and ethnic inequities. The Rhode Island Asthma Integrated Response (RI-AIR) program was developed to address current limitations in care. The aims of the RI-AIR Hybrid Type II effectiveness-implementation trial were to: a) simultaneously evaluate the effectiveness of RI-AIR on individual-level and community-level outcomes; b) evaluate implementation strategies used to increase uptake of RI-AIR. In this manuscript, we outline the design and methods used to implement RI-AIR.

METHODS

School-based areas (polygons) with the highest asthma-related urgent healthcare utilization in Greater Providence, R.I., were identified using geospatial mapping. Families with eligible children (2-12 years) living in one of the polygons received evidence-based school- and/or home-based asthma management interventions, based on asthma control level. School-based interventions included child and caregiver education programs and school staff trainings. Home-based interventions included individualized asthma education, home-environmental assessments, and strategies and supplies for trigger remediation. Implementation strategies included engaging school nurse teachers as champions, tailoring interventions to school preferences, and engaging families for input.

RESULTS

A total of 6420 children were screened throughout the study period, 811 were identified as eligible, and 433 children were enrolled between November 2018 and December 2021.

CONCLUSIONS

Effective implementation of pediatric asthma interventions is essential to decrease health inequities and improve asthma management. The RI-AIR study serves as an example of a multi-level intervention to improve outcomes and reduce disparities in pediatric chronic disease.

Multiancestral polygenic risk score for pediatric asthma

BACKGROUND

Asthma is the most common chronic condition in children and the third leading cause of hospitalization in pediatrics. The genome-wide association study catalog reports 140 studies with genome-wide significance. A polygenic risk score (PRS) with predictive value across ancestries has not been evaluated for this important trait.

OBJECTIVES

This study aimed to train and validate a PRS relying on genetic determinants for asthma to provide predictions for disease occurrence in pediatric cohorts of diverse ancestries.

METHODS

This study applied a Bayesian regression framework method using the Trans-National Asthma Genetic Consortium genome-wide association study summary statistics to derive a multiancestral PRS score, used one Electronic Medical Records and Genomics (eMERGE) cohort as a training set, used a second independent eMERGE cohort to validate the score, and used the UK Biobank data to replicate the findings. A phenome-wide association study was performed using the PRS to identify shared genetic etiology with other phenotypes.

RESULTS

The multiancestral asthma PRS was associated with asthma in the 2 pediatric validation datasets. Overall, the multiancestral asthma PRS has an area under the curve (AUC) of 0.70 (95% CI, 0.69-0.72) in the pediatric validation 1 and AUC of 0.66 (0.65-0.66) in the pediatric validation 2 datasets. We found significant discrimination across pediatric subcohorts of European (AUC, 95% CI, 0.60 and 0.66), African (AUC, 95% CI, 0.61 and 0.66), admixed American (AUC, 0.64 and 0.70), Southeast Asian (AUC, 0.65), and East Asian (AUC, 0.73) ancestry. Pediatric participants with the top 5% PRS had 2.80 to 5.82 increased odds of asthma compared to the bottom 5% across the training, validation 1, and validation 2 cohorts when adjusted for ancestry. Phenome-wide association study analysis confirmed the strong association of the identified PRS with asthma (odds ratio, 2.71, PFDR = 3.71 × 10-65) and related phenotypes.

CONCLUSIONS

A multiancestral PRS for asthma based on Bayesian posterior genomic effect sizes identifies increased odds of pediatric asthma.

Family asthma management in urban children and its association with sleep outcomes

Asthma symptoms impact children's sleep quality. However, it is unclear how families' daily management of their child's asthma is associated with sleep quality. We examine associations between family asthma management components and sleep duration and quality for urban children (ages 7-9 years). Additionally, we examine these associations by racial/ethnic group. Data were collected as part of a longitudinal study that examined the co-occurrence of asthma, allergic rhinitis, sleep quality, and academic functioning for urban children diagnosed with persistent asthma (N = 196). A semi-structured interview assessed family asthma management practices. Sleep quality data were collected via actigraphy. Our visual depiction of sleep outcomes show that those with higher family asthma management ratings present with longer sleep duration and better sleep quality. Among specific family asthma management components, we found a significant association between children's adherence to asthma medications and number of nighttime awakenings. For non-Latino Black (NLB) children, we found a significant association between environmental control and sleep duration. For urban children with asthma, clinical strategies to enhance overall family asthma management have the potential to support improved sleep quality. Additionally, for NLB children, asthma management interventions that provide environmental control practices may increase sleep duration.

Sociodemographic Differences in Asthma Self-Management Knowledge of Parents Seeking Asthma Care for their Children in Pediatric Emergency Departments

To effectively support asthma self-management among children most at risk for poor outcomes, it is important to examine potential disparities in parents' asthma-related knowledge. This study draws on baseline data collected from a randomized controlled trial to analyze how knowledge of asthma self-management varies by sociodemographic characteristics in a racially and economically diverse sample of Medicaid-insured children seeking emergency asthma care (N=221). Multivariable linear regression revealed that parent race/ethnicity, preferred language, and education were independently associated with scores on the Asthma Self Management Knowledge Questionnaire, and there was a significant interaction between parent race/ethnicity and education. In analyses stratified by parent education level, Latinx race/ethnicity was associated with lower-self-management knowledge among parents with higher education level, but not among those with a lower level of education. Our findings call for further research to understand and address the unique barriers to improving asthma self-management knowledge among Latinx parents and parents with limited English proficiency.

Patterns of Asthma Medication Use across the Transition to High School

OBJECTIVE

Adherence to asthma controller medications is suboptimal among adolescents. We evaluated predictors of adherence and longitudinal patterns of medication use between 8th and 10th grade among a sample of youth of diverse race/ethnicity.

METHODS

Eighth graders with asthma on controller medications (N = 62; 40.0% non-Latino white; 23.7% Black; 37.3% Latino; 37.3% female) completed measures of medication beliefs, responsibility for asthma management, and family cohesion. Objective methods tracked medication use longitudinally.

RESULTS

Adherence declined during the high school transition, from 48.0% in eighth grade to 34.1% in tenth grade (F = 5.35, p < .01). Males had lower adherence (b = -10.11, SE = 5.37, p = .02, f2 = 0.11), as did Latino youth (b = -12.21, SE = 8.23, p = .03, f2 = 0.12). Family cohesion was associated with higher adherence (b = 4.38, SE = 1.98, p = .04, f2 = 0.06). Latent class models (LCMs) suggested a three-class model of longitudinal adherence patterns. This included low, declining adherence (Class 1 = 29%; higher proportion male, p = .02), high, sustained adherence (Class 2 = 26%, high family cohesion, p = .05, higher proportion female, p = .02), and low, sustained adherence (Class 3 = 45%; higher proportion Latino, p = .05, higher proportion male, p = .02).

CONCLUSIONS

Asthma medication adherence declined between 8th and 10th grade. LCMs indicated some youth have stable patterns of adherence (high or low), whereas others demonstrate declines. Gender differences were observed, and family cohesion was associated with higher, sustained adherence. Interventions building on family resources and targeting the barriers adolescents face are necessary to improve asthma management during this vulnerable period.

Evaluating Asthma Mobile Apps to Improve Asthma Self-Management: User Ratings and Sentiment Analysis of Publicly Available Apps

BACKGROUND

The development and use of mobile health (mHealth) apps for asthma management have risen dramatically over the past two decades. Asthma apps vary widely in their content and features; however, prior research has rarely examined preferences of users of publicly available apps.

OBJECTIVE

The goals of this study were to provide a descriptive overview of asthma mobile apps that are publicly available and to assess the usability of asthma apps currently available on the market to identify content and features of apps associated with positive and negative user ratings.

METHODS

Reviews were collected on June 23, 2020, and included publicly posted reviews until June 21, 2020. To characterize features associated with high or low app ratings, we first dichotomized the average user rating of the asthma app into 2 categories: a high average rating and a low average rating. Asthma apps with average ratings of 4 and above were categorized as having a high average rating. Asthma apps with average ratings of less than 4 were categorized as having a low average rating. For the sentiment analysis, we modeled both 2-word (bi-gram) and 3-word (tri-gram) phrases which commonly appeared across highly rated and lowly rated apps.

RESULTS

Of the 10 apps that met the inclusion criteria, a total of 373 reviews were examined across all apps. Among apps reviewed, 53.4% (199/373) received high ratings (average ratings of 4 or 5) and 47.2% (176/373) received low ratings (average ratings of 3 or less). The number of ratings across all apps ranged from 188 (AsthmaMD) to 10 (My Asthma App); 30% (3/10) of apps were available on both Android and iOS. From the sentiment analysis, key features of asthma management that were common among highly rated apps included the tracking of peak flow readings (n=48), asthma symptom monitoring (n=11), and action plans (n=10). Key features related to functionality that were common among highly rated apps included ease of use (n=5). Users most commonly reported loss of data (n=14) and crashing of app (n=12) as functionality issues among poorly rated asthma apps.

CONCLUSIONS

Our study results demonstrate that asthma app quality, maintenance, and updates vary widely across apps and platforms. These findings may call into question the long-term engagement with asthma apps, a crucial factor for determining their potential to improve asthma self-management and asthma clinical outcomes.
