Evaluation of a School-Based Asthma Education Protocol.

School-based asthma education offers an opportunity to reach low-income children at risk for poor asthma control. Iggy and the Inhalers (Iggy) is an asthma education program that was implemented in a Midwest metropolitan school district. The purpose of this evaluation was to conduct a comprehensive program evaluation. Objectives included increasing children's asthma-related knowledge and families' awareness of asthma management, while cultivating collaboration between school nurses and asthma providers. A total of 173 students participated in Iggy education, with 147 completing both initial and 1-month posttests. Thirty-one parents and seven school nurses provided qualitative feedback. Iggy was well received by children, parents, and school nurses. Asthma knowledge increased significantly ( p < .001) between pretest and posttest, and this increase was retained at 1-month follow-up. This program evaluation suggests that our program had a significant, sustained impact on students' asthma knowledge. It also supports the value of collaboration between asthma providers and school nurses.

Creation and implementation of SAMPRO™: A school-based asthma management program.

Clinicians who care for children with asthma have an obligation to coordinate asthma care with the schools. Aside from routine clinical care of asthmatic children, providers must educate the family and child about the need for an asthma treatment plan in school and support the school nurse meeting the needs of the student requiring school-based asthma care. The following article was developed by multiple stakeholders to address this need. It describes the 4 components of the School-based Asthma Management Program (SAMPRO™). SAMPRO™ details elements necessary for the education of children, families, clinicians, and school-based personnel based on a "circle of support" that would enhance multidirectional communication and promote better care for children with asthma within the school setting.

Genome-wide association study of lung function phenotypes in a founder population.

BACKGROUND: Lung function is a long-term predictor of mortality and morbidity. OBJECTIVE: We sought to identify single nucleotide polymorphisms (SNPs) associated with lung function. METHODS: We performed a genome-wide association study (GWAS) of FEV1, forced vital capacity (FVC), and FEV1/FVC in 1144 Hutterites aged 6 to 89 years, who are members of a founder population of European descent. We performed least absolute shrinkage and selection operation regression to select the minimum set of SNPs that best predict FEV1/FVC in the Hutterites and used the GRAIL algorithm to mine the Gene Ontology database for evidence of functional connections between genes near the predictive SNPs. RESULTS: Our GWAS identified significant associations between FEV1/FVC and SNPs at the THSD4-UACA-TLE3 locus on chromosome 15q23 (P = 5.7 × 10(-8) to 3.4 × 10(-9)). Nine SNPs at or near 4 additional loci had P < 10(-5) with FEV1/FVC. Only 2 SNPs were found with P < 10(-5) for FEV1 or FVC. We found nominal levels of significance with SNPs at 9 of the 27 previously reported loci associated with lung function measures. Among a predictive set of 80 SNPs, 6 loci were identified that had a significant degree of functional connectivity (GRAIL P < .05), including 3 clusters of ß-defensin genes, 2 chemokine genes (CCL18 and CXCL12), and TNFRSF13B. CONCLUSION: This study identifies genome-wide significant associations and replicates results of previous GWASs. Multimarker modeling implicated for the first time common variation in genes involved in antimicrobial immunity in airway mucosa that influences lung function.

The effects of combining Web-based eHealth with telephone nurse case management for pediatric asthma control: a randomized controlled trial.

BACKGROUND: Asthma is the most common pediatric illness in the United States, burdening low-income and minority families disproportionately and contributing to high health care costs. Clinic-based asthma education and telephone case management have had mixed results on asthma control, as have eHealth programs and online games. OBJECTIVES: To test the effects of (1) CHESS+CM, a system for parents and children ages 4-12 years with poorly controlled asthma, on asthma control and medication adherence, and (2) competence, self-efficacy, and social support as mediators. CHESS+CM included a fully automated eHealth component (Comprehensive Health Enhancement Support System [CHESS]) plus monthly nurse case management (CM) via phone. CHESS, based on self-determination theory, was designed to improve competence, social support, and intrinsic motivation of parents and children. METHODS: We identified eligible parent-child dyads from files of managed care organizations in Madison and Milwaukee, Wisconsin, USA, sent them recruitment letters, and randomly assigned them (unblinded) to a control group of treatment as usual plus asthma information or to CHESS+CM. Asthma control was measured by the Asthma Control Questionnaire (ACQ) and self-reported symptom-free days. Medication adherence was a composite of pharmacy refill data and medication taking. Social support, information competence, and self-efficacy were self-assessed in questionnaires. All data were collected at 0, 3, 6, 9, and 12 months. Asthma diaries kept during a 3-week run-in period before randomization provided baseline data. RESULTS: Of 305 parent-child dyads enrolled, 301 were randomly assigned, 153 to the control group and 148 to CHESS+CM. Most parents were female (283/301, 94%), African American (150/301, 49.8%), and had a low income as indicated by child's Medicaid status (154/301, 51.2%); 146 (48.5%) were single and 96 of 301 (31.9%) had a high school education or less. Completion rates were 127 of 153 control group dyads (83.0%) and 132 of 148 CHESS+CM group dyads (89.2%). CHESS+CM group children had significantly better asthma control on the ACQ (d = -0.31, 95% confidence limits [CL] -0.56, -0.06, P = .011), but not as measured by symptom-free days (d = 0.18, 95% CL -0.88, 1.60, P = 1.00). The composite adherence scores did not differ significantly between groups (d = 1.48%, 95% CL -8.15, 11.11, P = .76). Social support was a significant mediator for CHESS+CM's effect on asthma control (alpha = .200, P = .01; beta = .210, P = .03). Self-efficacy was not significant (alpha = .080, P = .14; beta = .476, P = .01); neither was information competence (alpha = .079, P = .09; beta = .063, P = .64). CONCLUSIONS: Integrating telephone case management with eHealth benefited pediatric asthma control, though not medication adherence. Improved methods of measuring medication adherence are needed. Social support appears to be more effective than information in improving pediatric asthma control.

Using action research to implement an integrated pediatric asthma case management and eHealth intervention for low-income families.

Asthma case management and education programs improve pediatric asthma outcomes, but designing rigorous randomized controlled studies that accurately measure effects while encouraging parent participation is challenging. This is especially so for low-income African American families, who face significantly more severe asthma and social stress than their middle-class counterparts. Action research can help health education researchers negotiate between the elegant and complex designs favored by scientists with the real-life challenges of recruitment, implementation, and retention. This article discusses how a multidisciplinary team uses action research concepts to continuously adjust originally proposed protocols through the planning and implementation phases to encourage participation in a year-long randomized controlled trial of a program that combines telephone asthma case management and comprehensive online asthma education. As a result of these efforts, a higher proportion of low-income African American families are recruited into the study than originally proposed.

Fractional exhaled nitric oxide measurements are most closely associated with allergic sensitization in school-age children.

BACKGROUND: Factors affecting fractional exhaled nitric oxide (FeNO) in early childhood are incompletely understood. OBJECTIVE: To examine the relationships between FeNO and allergic sensitization, total IgE, atopic dermatitis, rhinitis, asthma, and lung function (spirometry) in children. METHODS: Children at high risk of asthma and other allergic diseases because of parental history were enrolled at birth and followed prospectively. FeNO was measured by an online technique at ages 6 and 8 years. Relationships among FeNO, various atopic characteristics, and asthma were evaluated. RESULTS: Reproducible FeNO measurements were obtained in 64% (135/210) of 6-year-old and 93% (180/194) of 8-year-old children. There was seasonal variability in FeNO. Children with aeroallergen sensitization at ages 6 and 8 years had increased levels of FeNO compared with those not sensitized (geometric mean; 6 years, 10.9 vs 6.7 parts per billion [ppb], P < .0001; 8 years, 14.6 vs 7.1 ppb, P < .0001). FeNO was higher in children with asthma than in those without asthma at 8 years but not 6 years of age (6 years, 9.2 vs 8.3 ppb, P = .48; 8 years, 11.5 vs 9.2 ppb, P = .03). At 8 years of age, this difference was no longer significant in a multivariate model that included aeroallergen sensitization (P = .33). There were no correlations between FeNO and spirometric indices at 6 or 8 years of age. CONCLUSION: These findings underscore the importance of evaluating allergen sensitization status when FeNO is used as a potential biomarker in the diagnosis and/or monitoring of atopic diseases, particularly asthma.

Internet telehealth for pediatric asthma case management: integrating computerized and case manager features for tailoring a Web-based asthma education program.

This article reports on the development of a personalized, Web-based asthma-education program for parents whose 4- to 12-year-old children have moderate to severe asthma. Personalization includes computer-based tailored messages and a human coach to build asthma self-management skills. Computerized features include the Asthma Manager, My Calendar/Reminder, My Goals, and a tailored home page. These are integrated with monthly asthma-education phone calls from an asthma-nurse case manager. The authors discuss the development process and issues and describe the current randomized evaluation study to test whether the year-long integrated intervention can improve adherence to a daily asthma controller medication, asthma control, and parent quality of life to reduce asthma-related healthcare utilization. Implications for health education for chronic disease management are raised.
