Adolescent Knowledge of When to Use Inhaled Asthma Medications: Implications for Management.

ABSTRACT:

Purpose

It is unclear how often adolescents with persistent asthma know when to use different inhaled medications (as-needed rescue vs. daily controller; 'accurate use'), or whether this knowledge is associated with clinical asthma outcomes. This study aimed to characterize adolescent knowledge of accurate use; examine whether accurate use is associated with controller medication adherence, asthma symptoms, or exacerbations requiring acute health care services; and determine whether knowledge of accurate use improves following regular exposure to controller medications with school-based directly observed therapy (DOT).

Methods

We analyzed baseline and 7-month data from the School-Based Asthma Care for Teens trial. Adolescents (12-16 years) identified inhaled medications on a chart and stated when each is used. We compared accurate use with adolescent-reported adherence, recent symptoms, and asthma-related acute health care visits; and exposure to DOT. Analyses were limited to subjects with controller medication.

Results

Of 430 participants, 252 had controller medication at baseline. Knowledge of accurate use was described by 62%, and associated with adherence (odds ratio [OR]: 2.06, 95% confidence interval [CI]: 1.12-3.83). By 7 months, 313 adolescents had controller medication; 75% described accurate use, which was associated with adherence (OR: 3.46, 95% CI: 1.83-6.54), health care (OR: 0.39, 95% CI: 0.20-0.79), and DOT exposure (OR: 1.83, 95% CI: 1.10-3.32). Associations with adherence and health care at 7 months persisted in adjusted analyses.

Discussion

Adolescent knowledge of accurate medication use was linked with greater adherence (baseline, 7 months), less acute health care (7 months), and exposure to in-school DOT. Interventions to support adolescents with persistent asthma should consider school-based care strategies and facilitate adolescent understanding of when to use different medications.

Project description:ObjectiveAdequate symptom control is a problem for many people with asthma. We asked whether weekly email reports on monitored use of inhaled, short-acting bronchodilators might improve scores on composite asthma-control measures.MethodsThrough an investigational electronic medication sensor attached to each participant's inhaler, we monitored 4 months' use of inhaled, short-acting bronchodilators. Participants completed surveys, including the Asthma Control Test(TM) (ACT), to assess asthma control at entry and monthly thereafter. After the first month, participants received weekly email reports for 3 months. The reports summarized inhaled bronchodilator use during the preceding week and provided suggestions derived from National Asthma Education and Prevention Program (NAEPP) guidelines. Paired t-tests and random-effects mixed models were implemented to assess changes in primary asthma endpoints.ResultsThirty individuals participated in the 4-month study; 29 provided complete asthma control information. Mean age was 36.8 years (range: 19-74 years); 52% of respondents were female. Mean ACT scores were 17.6 (Standard Deviation [SD] = 3.35) at entry and 18.4 (SD = 3.60) at completion of the first month. No significant difference appeared between ACT values at entry and completion of the first month (p = 0.66); however, after participants began receiving email reports and online information about their inhaler use, mean ACT scores increased 1.40 points (95% CI: 0.61, 2.18) for each subsequent study month. Significant decreases occurred in 2-week histories of daytime symptoms (β = -1.35, 95% CI: -2.65, -0.04) and nighttime symptoms (β = -0.84, 95% CI: -1.25, -0.44); no significant change in activity limitation (β = -0.21, 95% CI: -0.69, 0.26) was observed. Participants reported increased awareness and understanding of asthma patterns, level of control, bronchodilator use (timing, location) and triggers, and improved preventive practices.ConclusionsWeekly email reports and access to online charts summarizing remote monitoring of inhaled bronchodilator frequency and location were associated with improved asthma control and a decline in day-to-day asthma symptoms.

Project description:ImportanceDaily use of inhaled corticosteroids is a widely recommended treatment for mild persistent asthma in children. There is concern that, similar to systemic corticosteroids, inhaled corticosteroids may have adverse effects on bone health.ObjectiveTo determine whether there is an increased risk of bone fracture associated with inhaled corticosteroid use in children with asthma.Design, setting, and participantsIn this population-based nested case-control study, we used health administrative databases to identify a cohort of children aged 2 to 18 years with a physician diagnosis of asthma between April 1, 2003, and March 31, 2014, who were eligible for public drug coverage through the Ontario Drug Benefit Program (Ontario, Canada). We matched cases of first fracture after asthma diagnosis to fracture-free controls (ratio of 1 to 4) based on date of birth (within 1 year), sex, and age at asthma diagnosis (within 2 years). We used a 1-year lookback period to ascertain history of inhaled corticosteroid use. Multivariable conditional logistic regression was used to obtain an odds ratio (OR) with 95% confidence interval for fracture, comparing no inhaled corticosteroid use vs current, recent, and past use.ExposuresInhaled corticosteroid use during the child's 1-year lookback period, measured as current user if the prescription was filled less than 90 days prior to the index date, recent user (91-180 days), past user (181-365 days), or no use.Main outcomes and measuresFirst emergency department visit for fracture after asthma diagnosis, identified using International Statistical Classification of Diseases and Related Health Problems, 10th Revision codes.ResultsThis study included 19 420 children (61.0% male; largest proportion of children, 31.5%, were aged 6-9 years at their index date). The multivariable regression results did not show a significant association between first fracture after asthma diagnosis and current use (OR, 1.07; 95% CI, 0.97-1.17), recent use (OR, 0.96; 95% CI, 0.86-1.07), or past use (OR, 1.00; 95% CI, 0.91-1.11) of inhaled corticosteroids, compared with no use, while adjusting for sociodemographic factors and other medication use. However, use of systemic corticosteroids in the 1-year lookback period resulted in greater odds of fracture (OR, 1.17; 95% CI, 1.04-1.33).Conclusions and relevanceSystemic corticosteroids, but not inhaled corticosteroids, were significantly associated with increased odds of fracture in the pediatric asthma population.
