Practical evaluation of asthma exacerbation self-management in children and adolescents

Asthma and Rhinitis Through the Lifespan of Nonpregnant Women

Increasingly, clinical practice guidelines advocate a precision medicine-based approach to care for asthma. This focus requires knowledge of not only different asthma phenotypes and their associated biomarkers but also sex and gender differences through the lifespan. Evidence continues to build in favor of different lifetime prevalence, clinical presentations, responses to management, and long-term prognosis of asthma. Women transition through many biological and psychosocial phases in their lives, all of which may interact with, and influence, their health and well-being. Historically, explanations have focused on hormonal effects on asthma in reproductive life, but a greater understanding of mechanisms starting before birth and changing over a lifetime is now possible, with immunologic, inflammatory, and hormonal factors playing a role. This article describes the evidence for the differences in asthma and rhinitis between men and women at different stages of life, the potential underlying mechanisms that contribute to this, and the implications for management and research. Future research studies should systematically report sex differences in asthma so that this knowledge can be used to develop a personalized approach to care, to achieve best possible outcomes for all.

Treatment Adherence in Adolescents with Asthma

The burden of asthma is particularly notable in adolescents, and is associated with higher rates of prevalence and mortality compared with younger children. One factor contributing to inadequate asthma control in adolescents is poor treatment adherence, with many pediatric studies reporting mean adherence rates of 50% or lower. Identifying the reasons for poor disease control and adherence is essential in order to help improve patient quality of life. In this review, we explore the driving factors behind non-adherence in adolescents with asthma, consider their consequences and suggest possible solutions to ensure better disease control. We examine the impact of appropriate inhaler choice and good inhaler technique on adherence, as well as discuss the importance of selecting the right medication, including the possible role of as-needed inhaled corticosteroids/long-acting β₂-agonists vs short-acting β₂-agonists, for improving outcomes in patients with mild asthma and poor adherence. Effective patient/healthcare practitioner communication also has a significant role to engage and motivate adolescents to take their medication regularly.

Age and African-American race impact the validity and reliability of the asthma control test in persistent asthmatics

Background

The Asthma Control Test (ACT) is widely used to assess asthma control, yet the validity and reliability of the test have not been specifically evaluated in adolescents or African-Americans. We conducted a prospective psychometric study of the ACT in African-American (AA) and non-African-American (nAA) adolescents with persistent asthma, with emphasis on the clinical utility of the test for medical decision making.

Methods

Participants completed the ACT and performed spirometry. A physician conducted a guidelines-based assessment of asthma control, blinded to the ACT score. Study procedures were repeated 6–8 weeks later. The ACT-based asthma control assessment was compared to physician assessment.

Results

For baseline and follow-up visits, internal consistency, as measured using Cronbach’s alpha, was 0.80 and 0.81 in AA teens and 0.80 and 0.83 in nAA teens. Intraclass correlation coefficients were 0.59 and 0.76 in AA and nAA teens, respectively, with stable asthma control over time. Agreement between ACT and physician assessment was moderate in AA teens and fair in nAA teens. An ACT score of ≤19 showed reduced sensitivity for not well controlled asthma in both groups, while a score of ≤21 had the greatest area under the ROC curve. ACT scores were marginally responsive to change in control status.

Conclusions

Concerns for the ACT’s ability to detect uncontrolled asthma in adolescents emphasizes the need for a more comprehensive evaluation of asthma control in clinical settings. A higher threshold ACT score to define not well controlled asthma may be needed if the ACT is to be used for medical decision making.

[Therapeutic adherence in asthma in France: A general review]

INTRODUCTION

Adherence in asthma is a paramount issue of disease management. A general review of the French publications on this topic has been conducted.

METHODS

Research equations used for bibliographic databases (MEDLINE, Science Direct, Banque de données en santé publique, Cochrane and Cairn.info) comprised the following keywords: "asthma", "therapeutic adherence" and "France". These publications unrelated to asthma, focused on asthma management without exploring adherence, or those conducted in populations without French patients were excluded.

RESULTS

A total of 82 articles have been selected (36 surveys, 4 randomized trials and 42 reviews/syntheses). Whatever the methodology used and publication year, the inadequate therapeutic adherence in asthma was steadily reported, notably for controllers and the quality of use of inhaled devices.

CONCLUSION

The present review highlights the sustainability of adherence-related issues in asthma and the need to improve patients' knowledge on asthma and the finality of therapy. It also highlights the need of an improved communication between patients and physicians is also advocated. Further studies with more recent data are desirable to assess changes in disease management of asthma and the impact of potential future corrective interventions.

[Prescription of asthma action plans in the Aquitaine region of France]

INTRODUCTION

Although guidelines recommend the prescription of written asthma action plans (WAAP), their use remains limited.

METHODS

A prospective survey was performed from 2013 to 2014. We interviewed respiratory physicians, paediatric respiratory physicians and allergologists taking care of asthmatic patients and practicing in the Aquitaine region of France, using computerized questionnaires, regarding their everyday practice in the use of WAAP.

RESULTS

A total of 59/143 (41%) clinicians, with a mean age of 47 years, participated in the study. A total of 41/59 (69.5%) were using a WAAP (12 different models with very inhomogeneous contents, mostly targeting symptoms only). WAAP prescribers were younger than non-prescribers, were more often female, working mostly in the Gironde area, with mixed hospital and private-based activity, and were paediatric-respiratory physicians or respiratory physicians. The severity of asthma had little influence on WAAP prescriptions.

CONCLUSION

In the Aquitaine region, prescription of WAAPs remains inadequate and shows large disparities. WAAP users are mostly younger female specialists.

Effect of depressive symptoms on asthma intervention in urban teens

BACKGROUND

The literature suggests that depression is an important comorbidity in asthma that can significantly influence disease management and quality of life (QOL).

OBJECTIVE

To study the effect of coexisting depressive symptoms on the effectiveness of self-management interventions in urban teens with asthma.

METHODS

We analyzed data from a randomized controlled trial of Puff City, a web-based, tailored asthma management intervention for urban teens, to determine whether depression modulated intervention effectiveness for asthma control and QOL outcomes. Teens and caregivers were classified as depressed based on responses collected from baseline questionnaires.

RESULT

Using logistic regression analysis, we found that a lower percentage of treatment students had indicators of uncontrolled asthma compared with controls (adjusted odds ratios <1). However, for teens depressed at baseline, QOL scores at follow-up were significantly higher in the treatment group compared with the control group for the emotions domain (adjusted relative risk, 2.08; 95% confidence interval, 1.2-3.63; P = .01; interpreted as emotional QOL for treatment students increased by a factor of 2.08 above controls). Estimates for overall QOL and symptoms QOL were borderline significant (adjusted relative risk, 1.57; 95% confidence interval, 0.93-2.63; P = .09; and adjusted relative risk, 1.72; 95% confidence interval, 0.94-3.15; P = .08; respectively). Among teens not depressed at baseline, no significant differences were observed between treatment and control groups in QOL domains at follow-up.

CONCLUSION

Our results suggest that depression modified the relationship between the effectiveness of an asthma intervention and emotional QOL in urban teens. Further assessment of self-management behavioral interventions for asthma should explore the mechanism by which depression may alter the intervention effect.

Telemanagement in asthma: an innovative and effective approach

PURPOSE OF REVIEW

Information and communication technology (ICT) could potentially help to reduce the considerable burden of asthma that still exists despite wide availability of effective therapies. Telemanagement is an interactive and proactive management approach consisting of an ongoing partnership of patients and professionals supported by ICT and focused on clinical outcomes and patient goals in the individual. This review highlights recent developments in telemanagement in the ongoing management of patients with asthma focused on the effectiveness, cost-effectiveness and implementation of telemanagement in asthma care.

RECENT FINDINGS

An increasing number of studies address the effectiveness of components or a comprehensive telemanagement intervention in children and adults with mild to severe asthma. Telemanagement of asthma in the individual patient includes key components of asthma management, such as education, self-monitoring, goal setting, written action plans and regular medical review. Such a comprehensive telemanagement approach is effective in improving quality of life and clinical outcomes, especially in adult patients with moderate to severe asthma.

CONCLUSION

Telemanagement of asthma can be an effective and cost-effective approach tailored to the individual patient needs. More research is needed on the long-term effectiveness and cost-effectiveness of telemanagement of patients with asthma under real-world conditions and on effective implementation strategies.

Factors associated with nonresponse to a computer-tailored asthma management program for urban adolescents with asthma

BACKGROUND

The ability to identify potentially resistant participants early in the course of an intervention could inform development of strategies for behavior change and improve program effectiveness.

OBJECTIVE

The objective of this analysis was to identify factors related to nonresponse (i.e., lack of behavior change) to an asthma management intervention for urban teenagers. The intervention targeted several behaviors, including medication adherence, having a rescue inhaler nearby, and smoking.

METHODS

A discriminate analysis was conducted using data from a randomized trial of the intervention. Included in this analysis are participants who reported a physician diagnosis of asthma, completed a baseline questionnaire, were randomized to the treatment group, completed >or=2 of 4 educational sessions, and completed >or=2 of 3 follow-up questionnaires. Ninety students met criteria for inclusion in this subgroup analysis.

RESULTS

In logistic regression models for medication adherence, nonresponse was related to low baseline asthma self-regulation, odds ratio = 3.6 (95% confidence interval = 1.3-9.5). In models for having an inhaler nearby, nonresponse was related to low baseline self-regulation and to rebelliousness, OR = 4.7 (1.6-13.2) and 5.6 (1.7-18.0), respectively. Nonresponse to smoking messages was related to rebelliousness, low emotional support, and low religiosity, ORs = 7.6 (1.8-32.3), 9.5 (1.4-63.5), and 6.6 (1.5-29.8) respectively.

CONCLUSIONS

Certain variables had the ability to discriminate the likelihood of response from that of nonresponse to an asthma program for urban, African American adolescents with asthma. These variables can be used to identify resistant subgroups early in the intervention, allowing the application of specialized strategies through tailoring. These types of analyses can inform behavioral interventions.

Detection and home management of worsening asthma symptoms

BACKGROUND

Asthma guidelines recommend early home treatment of exacerbations. However, home treatment is often suboptimal and delayed.

OBJECTIVES

To describe antecedent symptoms and signs of asthma exacerbations noticed by parents and to learn when and how parents intensify asthma treatment.

METHODS

Parents of children 2 to 12 years old with asthma exacerbations that required urgent care in the past 12 months completed telephone questionnaires. Where multiple responses were possible, percentages may sum to more than 100%.

RESULTS

One hundred one parents were enrolled and interviewed; 94% were the children's mothers. Seventy percent of the children were black, and 64% had Medicaid insurance. Parents reported multiple antecedent symptoms and signs (median number per child, 3; range, 1-6), including respiratory symptoms (79%), allergy or cold symptoms (43%), behavioral changes (24%), and other nonspecific symptoms (29%). Twenty-three parents reported late respiratory symptoms, such as gasping for breath and using accessory muscles to breath, as the earliest antecedent signs. Treatment was most often intensified when the parent noticed cough (55%), shortness of breath (54%), and wheeze (25%) and included adding albuterol (92%), an oral corticosteroid (17%), an inhaled corticosteroid (8%), or other nonasthma medications (16%).

CONCLUSIONS

Although parents described antecedent symptoms and signs of impending asthma exacerbations that they consistently noticed in their children, many waited for lower respiratory signs to be present before intensifying treatment. Oral corticosteroids were used infrequently. Interventions to improve the ability of parents and children to accurately recognize worsening symptoms and initiate timely, effective treatment are needed.

Home use of albuterol for asthma exacerbations

BACKGROUND

To reduce symptoms and emergency department (ED) visits, the National Asthma Education and Prevention Program (NAEPP) guidelines recommend early treatment of acute asthma symptoms with albuterol and oral corticosteroids. Yet, ED visits for asthma are frequent and often occur several days after onset of increased symptoms, particularly for children from low-income, urban neighborhoods.

OBJECTIVES

To describe home use of albuterol and identify factors associated with appropriate albuterol use.

METHODS

A total of 114 caregivers in the intervention group of a randomized trial to reduce emergent care for low-income, urban children completed a structured telephone interview with an asthma nurse to evaluate home management of their child's acute asthma symptoms. Interviews lasted approximately 20 minutes and were conducted from November 5, 2003, through September 30, 2005. Albuterol use as reported by caregivers was categorized as appropriate or inappropriate based on NAEPP recommendations.

RESULTS

Albuterol use for worsening asthma symptoms was categorized as appropriate for only 68% of caregivers and was more likely if the children had an ED visit or hospitalization for asthma in the prior year. The remaining 32% of caregivers used albuterol inappropriately (overtreatment or undertreatment). Appropriate albuterol use was not associated with caregiver report of having an asthma action plan (AAP) or a recent primary care physician visit to discuss asthma maintenance care.

CONCLUSIONS

Caregivers reported that they would use albuterol to treat their child's worsening asthma symptoms, but many described inappropriate use. Detailed evaluation of proper albuterol use at home may provide insight into how health care professionals can better educate and support parents in their management of acute exacerbations and more effective use of AAPs.

Agreement between teenager and caregiver responses to questions about teenager's asthma

It is unknown if teenagers and caregivers give similar responses when interviewed about the teen's asthma. We analyzed data for 63 urban African-American teen-caregiver pairs. Caregivers underestimated teen smoking by 30%, gave lower estimates for teen exposure to passive smoke, and disagreed with teens on controller medication usage. Teen-caregiver responses were not significantly different for estimates of symptom-days, activity limitations, or nights awakened; nor were they significantly different for report of emergency department visits or hospitalizations. Agreement was weak for perceived asthma control and severity. Teen-caregiver agreement on asthma depends on the type of information being sought.

Clinical and therapeutic aspects of allergic asthma in adolescents

Little is known about the management of asthma in adolescents. We aimed at evaluating these aspects, through a specific questionnaire, in the real life of adolescents with allergic asthma. The questionnaire was administered to a group of adolescents after a diagnosis of allergic asthma. The diagnosis was based on history, clinical examination, pulmonary function tests and allergy tests. One hundred and fifteen adolescents (65 males, mean age 16.5 years) fulfilled the criteria for allergic asthma. The questionnaire explored demography, family history, clinical history, previous diagnosis, therapy, attitude towards therapy and social aspects. The mean actual FEV1 was 87 +/- 10%. Methacholine challenge was carried out in 79 patients and was always positive (PD20 < 1,200 microg), whereas 36 patients underwent reversibility test. According to GINA guidelines, severity of asthma resulted intermittent in 62, mild persistent in 31, moderate in 19 and severe in three patients. In 61% of cases teachers were not aware of the disease. Asthma was managed by general practitioners, allergists and pulmonologists, but PFT/allergy tests had never been performed in 14% of patients. Forty-two per cent of the adolescents received no therapy at all, and only 15% of those with persistent asthma were receiving a stable treatment. Seventy-four per cent of adolescents preferred the inhaled, as against the oral, route. From a clinical and functional point of view, asthma in adolescents did not differ from other age ranges. Nevertheless, the management (diagnosis and therapy) emerged to be unsatisfactory from many points of view.
