Treatment adherence and level of control in moderate persistent asthma in children and adolescents treated with fluticasone and salmeterol

Association between fractional exhaled nitric oxide and therapeutic adherence to controller management in pediatric asthma patients

OBJECTIVES

Guidelines for asthma management recommend, before establishing additional therapeutic behaviors, to confirm correct use and adequate therapeutic adherence to treatment. Evidence exists on the use of fractional exhaled nitric oxide (FeNO) values for monitoring therapeutic adherence in adults. It is important to establish whether there is a correlation between FeNO and therapeutic adherence in children. This study aims to provide new knowledge about the relationship between FeNO and therapeutic adherence in asthmatic children.

MATERIALS AND METHODS

Analytical cross-sectional study including asthma patients 5-18 years of age, attending follow-up at Hospital Militar Central (HMC) between May and November 2022 in Colombia. A sociodemographic survey was carried out, followed by the Pediatric Inhaler Adherence Questionnaire (PIAQ), and asthma control test (ACT) or childhood asthma control test (cACT). We defined adequate therapeutic adherence as not missing a single application of inhaled steroids in the last 15 days according to PIAQ. A poisson regression model was carried out including relevant predictors for therapeutic adherence such as FeNO values, age, tobacco exposure at home, atopy, and time since initiation of use of inhaled controller.

RESULTS

Eighty-two children with a median age of 10 years (interquartile range: 7-12 years) were included. Adequate therapeutic adherence was reported by 68.3%. After adjusting for age, sex, exposure to cigarette smoke, duration of controller therapy, and atopy, FeNO < 20 ppb was independently associated with adequate therapeutic adherence (RR = 1.5, p = .04, 95% confidence interval: 1.03-2.19).

CONCLUSIONS

FeNO values seem to be useful to identify pediatric patients with asthma who have adequate adherence to inhaled steroids in a MIC.

Effect of motivational interviewing on treatment adherence and self-efficacy of adolescents with asthma: A randomized controlled trial

AIMS

This study examined the short-term effect of motivational interviewing on treatment adherence and self-efficacy of adolescents with asthma.

DESIGN

The randomized controlled trial.

METHOD

In this study, 72 adolescents with asthma were recruited and assigned to experimental and control groups randomly. In the experimental group, the motivational interviewing was performed for five weekly sessions lasting 80-90 min. The treatment adherence and self-efficacy questionnaires were completed before the intervention, 2 weeks and 3 months after the intervention in both groups. Data were analysed by Chi-Square test, independent samples T-test, repeated measures of Wilcoxon and generalized estimating equation.

RESULTS

The treatment adherence was found to be significantly higher 2 weeks (p = 0.006) and 3 months after the intervention (p = 0.04) in the experimental group than the control group. In addition, the degree of self-efficacy was significantly more in the experimental group 2 weeks (p < 0.001) and 3 months later (p < 0.001) than the control group. The result of generalized estimating equation showed that the intervention group had an average of 14.44 more self-efficacy points than the control group (p < 0.001). Also, treatment adherence in the intervention group was significantly higher than the control group (β = 6.14, p = 0.05(.

CONCLUSION

This study adds to the evidence for the effectiveness of motivational interviewing in treatment of adolescents with asthma.

Asthma control in Brazil: a systematic review

Objectives: To explore asthma control in patients undergoing pharmacotherapy on studies in the last 20 years in Brazil. Asthma is a chronic airway inflammation disease with a high prevalence worldwide. Even with a variety of drug treatment improvements, attaining asthma control is challenging, since it should have a personalized approach. In Brazil, studies on the prevalence of asthma control are scarce and usually from a small sample size.Data Sources: A systematic review was performed to assess asthma control in Brazilian population. Terms related to "asthma", "asthma control" and "Brazil" were used in the search strategies in PubMed, BVSalud, Embase and Cochrane Library, including Brazilian Journal of Allergy and Immunology as data sources. A narrative synthesis was performed to report key outcome.Study Selections: In total, 23 studies were included. Most of them were conducted in the Southeastern and Northeast regions, in a short duration.Results: Pediatric and non-pediatric population were assessed, with a higher proportion of female. In pediatric population, those with poorly controlled asthma usually had severe or persistent disease. In elderly, an increased asthma severity was found, although proper treatment might be effective. Most studies (70%) also described exacerbations, hospitalizations (48%), quality of life (39%), and emergency visits (30%). Despite heterogeneity of outcomes and population, studies show an important prevalence of uncontrolled asthma even in patients being treated, with better disease control with treatment improvements.Conclusions: Studies in Brazil have shown that asthma control remains a challenge and there is still a need for improvement on disease management.

The Impact of Adherence and Health Literacy on Difficult-to-Control Asthma

Medication nonadherence and health literacy are key factors that influence the management of difficult-to-control asthma. Adherence, or the extent to which a patient follows a treatment plan, extends beyond asthma medication use and includes an appropriate inhaler technique. Assessment of adherence is critical before making a diagnosis of severe asthma and stepping up asthma therapy but is challenging in the clinical context. Health literacy, or the degree to which individuals can obtain, process, and understand health information and services needed to make health care decisions, is additionally important for asthma management and has been shown to impact medication adherence. Initiatives aiming to improve difficult-to-control asthma should address medication adherence and health literacy. Universal health literacy precautions are recommended while communicating with patients, in addition to the creation of low health literacy asthma action plans. To improve adherence, a comprehensive assessment of adherence should be conducted. Additional evidence-based interventions aiming to improve adherence focus on appropriate inhaler use, improved access to medications, the use of digital platforms, school-based asthma interventions, and the implementation of culturally tailored interventions. Data are limited regarding the use of these initiatives in patients with severe or difficult-to-control asthma.

Effectiveness of individualized inhaler technique training on low adherence (LowAd) in ambulatory patients with COPD and asthma

To analyze whether there is improvement in adherence to inhaled treatment in patients with COPD and asthma after an educational intervention based on the teach-to-goal method. This is a prospective, non-randomized, single-group study, with intervention and before-after evaluation. The study population included 120 patients (67 females and 53 males) diagnosed with asthma (70.8%) and COPD (29.1%). The level of adherence (low and optimal) and the noncompliance behavior pattern (erratic, deliberate and unwitting) were determined by the Test of the adherence to Inhalers (TAI). This questionnaire allows you to determine the level of adherence and the types of noncompliance. Low Adherence (LowAd) was defined as a score less than 49 points. All patients received individualized educational inhaler technique intervention (IEITI). Before the IEITI, 67.5% of the patients had LowAd. Following IEITI, on week 24, LowAd was 55% (p = 0.024). Each patient can present one or more types of noncompliance. The most frequent type was forgetting to use the inhaler (erratic), 65.8%. The other types were deliberate: 43.3%, and unwitting: 57.5%. All of them had decreased on the final visit: 51.7% (p = 0.009), 25.8% (p = 0.002), 39.2% (p = 0.002). There were no significant differences in adherence between asthma and COPD patients at the start of the study. The only predicting factor of LowAd was the female gender. An individualized educational intervention, in ambulatory patients with COPD and asthma, in real-world clinical practice conditions, improves adherence to the inhaled treatment.

Psychosocial factors and lack of asthma knowledge undermine child and adolescent adherence to inhaled corticosteroid

This study aimed to evaluate inhaled corticosteroid (ICS) adherence and identify factors associated with non-adherence in pediatric asthma patients. A total of 134 patients aged 8-18 years old were included. At the first visit, patient adherence, asthma knowledge, and outcome expectation data were collected and recorded. Depression, anxiety, and self-esteem were assessed using psychiatric questionnaires. After providing asthma education, reevaluation of adherence and asthma control was performed at one 3- to 6-month follow-up visit. The mean ICS adherence was 75.9 ± 27.5%. Fifty-seven patients (42.5%) were defined as having poor adherence (<75%). "Intentional" and "hectic lifestyle and forgetfulness" were the main reasons for missing ICS doses in mid-late adolescents and children, respectively. Asthma knowledge generally improved with age. Overall, 89% and 67.7% of patients could define symptoms and triggers of asthma, respectively; however, less than 25% understood how asthma affected their body and the chronic nature of asthma. Patients with ICS adherence <75% had unfavorable expectations from asthma treatment (odds ratio [OR]: 1.05, 95% confidence interval [CI]: 1.01-1.10), and a higher proportion of inhaled short-acting beta-agonist use before exercise (OR: 4.12, 95% CI: 1.27-13.36). Depression and anxiety were frequently found (27.5%) and 23.3%, respectively; p > 0.05). Significant improvement in ICS adherence (p = 0.02) and Asthma Control Test scores (p = 0.02) were observed at the follow-up visit. Patient outcome expectations could be predictors of ICS adherence. Patient education regarding the mechanism and nature of asthma should be considered as an intervention for improving pediatric patient adherence. Psychological evaluation is warranted in pediatric patients with asthma.

The impact of using a mobile application to improve asthma patients' adherence to medication in Jordan

The main aim of this study is to assess the effectiveness of using a developed asthma mobile application to enhance medication adherence in Jordan. Asthma patients visiting outpatient respiratory clinics and using inhalers were recruited. Patients were assigned into two groups: intervention and control. The intervention group was instructed to download and use the application. Asthma control was assessed using Asthma Control Test (ACT) at baseline and at follow-up of 3 months for both groups. A total of 171 patients (control, n = 83, and intervention, n = 88) participated in the study. After 3 months of usage, patients in the intervention group achieved a significant improvement in ACT score compared to control (p-value <0.05), and reported a significant satisfaction of the application use. Therefore, the asthma mobile application is found as an effective tool to enhance medication adherence in asthma patients.

Electronic adherence monitoring devices for children with asthma: A systematic review and meta-analysis of randomised controlled trials

BACKGROUND

Asthma is a common chronic condition amongst children. Poor adherence to asthma medications can increase asthma exacerbations, absence from school, healthcare utilisation and costs and decrease quality of life. Emerging evidence suggests the use of electronic adherence monitoring devices in improving children's adherence to medications.

OBJECTIVES

This study aimed to evaluate the effectiveness of electronic adherence monitoring devices in improving inhaler adherence amongst children with asthma.

DESIGN

This study is a systematic review and meta-analysis.

DATA SOURCES

A systematic search using Cochrane Library, PubMed, Embase, CINAHL, Web of Science, Scopus and ProQuest Dissertations and Theses from inception up to April 6, 2021, was conducted.

REVIEW METHODS

Randomised controlled trials evaluating the use of electronic adherence monitoring devices amongst children and published in English were included. The outcomes were inhaler adherence, asthma exacerbation, lung function, asthma control and accessibility. The overall effect was measured using Hedges' g and determined using Z-statistics at a significance level of p < 0.05. Heterogeneity was assessed using χ² and I² statistics. The individual and overall quality of evidence was assessed. Sensitivity and subgroup analyses were conducted. Narrative synthesis of outcomes was performed when meta-analysis could not be conducted on the data.

RESULTS

A total of 13,429 records were identified, and 10 randomised controlled trials in 11 articles amongst 1123 participants were included in the meta-analysis. Meta-analysis revealed that the electronic adherence monitoring device group was 1.50 times more likely to adhere to inhalers compared with the control group with medium-to-large effect size (g = 0.64). A series of subgroup analyses showed that no significant subgroup differences for inhaler adherence were found amongst different populations, comparator, setting, duration of the monitoring period, reminder, and feedback functions of the electronic adherence monitoring devices. Children found the devices as user friendly with high accessibility scores. However, no significant differences were observed between the intervention and control groups for asthma exacerbations, lung function and asthma control.

CONCLUSIONS

The findings from this study suggested that electronic adherence monitoring devices could improve inhaler adherence. Future devices should contain actuation and inhalation functions that can help to confirm actual inhalation amongst children with asthma. The overall evidence of outcomes ranged from very low to high. Furthermore, future large-scale trials were recommended before clinical implementations.

Adherence to Asthma Controller Therapy Among Children in Majmaah City, Saudi Arabia

Background and objective

Improving adherence to asthma medications may prevent asthma exacerbation, which is associated with a decline in lung function. The purpose of this study was to assess the adherence to asthma controller therapy and the factors that might influence the level of adherence among asthmatic children.

Materials and methods

We conducted a prospective observational study at the King Khalid Hospital in Majmaah, Saudi Arabia between January and April 2020; the study was conducted among children aged 1-14 years with a diagnosis of asthma. The data collected when available included age and gender by using a pre-tested questionnaire that contained four validated items, and the respondents were the parents of the affected children. Due to the coronavirus disease 2019 (COVID-19) pandemic, the data collection was performed via phone calls to ensure safety. Informed consent was obtained from the parents.

Results

We analyzed 152 asthmatic children to evaluate their adherence to asthma controller therapy. The majority of the children were males (60%). Asthma was most prevalent in the age group of 6-10 years (40.1%), followed by the age group of two to five years (32.9%). We found that the majority of the patients had poor adherence to asthma medication (83.6%) while the remaining had good adherence (16.4%). The total mean score for adherence to medication therapy was 5.16 (SD: 2.3).

Conclusions

The present study showed that the overall adherence level to the asthma controller therapy was poor among children. Larger, nationwide studies are needed to assess the adherence to asthma medications and implement interventions that can improve the same.

Medication Therapy Management for Texas MediCAID Patients With Asthma and Chronic Obstructive Pulmonary Disease-A Pilot Study

BACKGROUND

Pharmacists can play an important role in providing medication therapy management (MTM) services, which focus on appropriate medication use. This pilot study aimed to describe pharmacists' MTM service provision, results/outcomes of pharmacists' recommendations and resolution/acceptance rate among patients with high-risk asthma and/or chronic obstructive pulmonary disease (COPD).

METHODS

This was a prospective descriptive study of MTM services provided by community pharmacists to Texas Medicaid patients (5-63 years) with "high risk" asthma or COPD. Patients received in-person and telephone consultations that included medication review, asthma control test assessment, and education on adherence and proper medication/device use. Data extracted from MTM software was used to describe: reasons for MTM services, type of pharmacists' interventions, outcomes of pharmacists' recommendations and acceptance rate.

RESULTS

Twenty-eight pharmacists provided 139 MTM interventions with 63 patients (2.2 interventions per patient). The most frequent intervention reason was complex drug therapy (53.2%), underuse of medication (8.6%), need for drug therapy (8.6%), new or changed prescription therapy (6.5%), and administration technique (5.0%). The resolution rate was 77.7%. Patient and prescriber, respectively, refused recommendation in 12% and 6% of the interventions. Outcomes included comprehensive medication review (46.7%), improved adherence (6.5%), therapeutic success (6.5%), improved administration technique (5.0%), and initiation of new therapy (5.0%).

CONCLUSION

Through the provision of MTM, pharmacists were able to identify and intervene with medication-related problems. These interventions are instrumental in helping patients better manage their asthma/COPD. The high resolution rate was encouraging. Larger scale studies are needed to assess clinical and economic outcomes.

Role of adrenergic receptor signalling in neuroimmune communication

Neuroimmune communication plays a crucial role in maintaining homeostasis and promptly responding to any foreign insults. Sympathetic nerve fibres are innervated into all the lymphoid organs (bone marrow, thymus, spleen, and lymph nodes) and provide a communication link between the central nervous system (CNS) and ongoing immune response in the tissue microenvironment. Neurotransmitters such as catecholamines (epinephrine and norepinephrine) bind to adrenergic receptors present on most immune and non-immune cells, establish a local neuroimmune-communication system, and help regulate the ongoing immune response. The activation of these receptors varies with the type of receptor-activated, target cell, the activation status of the cells, and timing of activation. Activating adrenergic receptors, specifically β-adrenergic signalling in immune cells leads to activation of the cAMP-PKA pathway or other non-canonical pathways. It predominantly leads to immune suppression such as inhibition of IL-2 secretion and a decrease in macrophages phagocytosis. This review discusses the expression of different adrenergic receptors in various immune cells, signalling, and how it modulates immune cell function and contributes to health and diseases. Understanding the neuroimmune communication through adrenergic receptor signalling in immune cells could help to design better strategies to control inflammation and autoimmunity.

•

Primary and secondary lymphoid organs are innervated with sympathetic nerve fibres.

•

Adrenergic receptor expression on immune and non-immune cells establishes a local neuroimmune communication system.

•

Adrenergic receptor signalling in immune cells controls the differentiation and function of various immune cells.

•

Modulating adrenergic receptor signalling with a specific agonist or antagonist also affect the immune response.

Potential normalization of an asthma mHealth intervention in community pharmacies: Applying a theory-based framework

BACKGROUND

Effective mobile health (mHealth) interventions have been developed to support patients with their medication use, however to date few are widely used in pharmacy practice. Normalization of an intervention is essential to have a population impact, which is defined as 'the process of getting a new intervention into routine practice'.

OBJECTIVE

The aim of this study was to assess the normalization potential of a complex mHealth intervention for adolescents with asthma (ADolescent Adherence Patient Tool; ADAPT) in community pharmacy practice.

METHODS

The Normalization Process Theory (NPT), a sociological action theory, was retrospectively applied to study the normalization potential of ADAPT. NPT explains factors that promote or hinder implementation, embedding, and integration of new interventions in clinical practice. Evaluation data (structured interviews and questionnaires) of 23 pharmacists who used the ADAPT intervention were used for this study.

RESULTS

Pharmacists understood the purpose of the ADAPT intervention and were prepared to undertake the necessary work of implementation. However changes at different levels are needed to support full normalization, such as changes in the intervention itself and changes in the pharmacist's work flow. The potential for normalization could also be enhanced by the use of product champions and appropriate reimbursement guidelines, to ensure uptake of the intervention by other pharmacists. Support from professional bodies for the use of mHealth could also promote normalization.

CONCLUSIONS

Normalization of mHealth is a complex continuous process. The ADAPT intervention has the potential to be normalized in community pharmacy practice, but full normalization would require changes in both daily pharmacy practice and reimbursement models.

Effect of a mHealth intervention on adherence in adolescents with asthma: A randomized controlled trial

BACKGROUND

Adherence rates among asthma patients are generally low and decrease during adolescence, resulting in poorly controlled asthma. The aim of our study was to evaluate the effectiveness of the ADolescent Adherence Patient Tool (ADAPT), an interactive mobile health (mHealth) intervention, in supporting self-management and improving inhaled corticosteroid adherence in adolescents with asthma.

METHODS

We conducted a cluster randomized controlled trial in 66 Dutch community pharmacies. Asthma patients aged 12-18 years were invited to participate, based on pharmacy medication refill records. The main study outcome was self-reported medication adherence, measured with the Medication Adherence Report Scale (MARS). Secondary outcomes were asthma control and quality of life. Outcomes were measured at start (t = 0 months) and at the end of follow-up (t = 6 months). Mixed-effects models were used to analyze the effect.

RESULTS

In total, 234 adolescents (147 in the control group and 87 in the intervention group) completed the study; mean age 15.1 ± 1.9 years and 52.6% females. Adherence rates of patients with low baseline adherence (MARS scores ≤19; n = 76) increased with 1.42 points in the intervention group (n = 26). Adherence rates of patients in the control group (n = 50) decreased with 0.70 points. Thus there was a positive effect of the intervention on medication adherence (MARS +2.12, p = 0.04). This effect was stronger (MARS +2.52, p = 0.02) in poor adherent adolescents with uncontrolled asthma (n = 74). No effect of the intervention was observed on asthma control or quality of life.

CONCLUSIONS

The ADAPT intervention increases medication adherence in adolescents with asthma having poor adherence rates at baseline. Healthcare providers should consider a tailored mHealth approach to improve the asthma treatment.

New insights to improve treatment adherence in asthma and COPD

Chronic respiratory diseases such as asthma and COPD are typically managed by daily inhaled medication. However, the efficacy of an inhaled medication depends upon a patient's adherence to therapy, which refers to whether the medication is actually taken as prescribed. In patients with these diseases, higher adherence has been associated with better health outcomes, such as improved disease control and a reduction in severe and potentially costly exacerbations. Adherence is a multifaceted concept that includes medication-related, intentional, and unintentional reasons that patients may or may not take their medication as directed. The purpose of this integrative review is to present the individual patient factors that contribute to suboptimal adherence to inhaled therapies and the associated effects on health outcomes, while also highlighting evidence-based strategies for health care providers to improve adherence to such therapies in patients with asthma or COPD. Working closely with patients to establish a model of shared decision-making, which takes patient beliefs and preferences into account when choosing treatment options, has the potential to improve adherence and overall patient outcomes in the management of asthma and COPD.

Adherence to treatment in allergic respiratory diseases

Introduction: Asthma and allergic rhinitis (AR) are chronic conditions in which management needs adherence to prescribed drugs. Despite the benefits of regular maintenance of asthma and AR therapy, low adherence is a frequent issue in clinical practice. Areas covered: The aim of this review is to provide a targeted analysis of the more recent literature on adherence in asthma and AR, focused on the following areas: adherence extent, barriers and consequences, effects of educational interventions and use of new technologies to improve the level of adherence. Expert commentary: Despite the extent, reasons and effects of this problem being well known, non-adherence in asthma and allergic AR remains worryingly high. Poor adherence leads to unsatisfactory health outcomes, with a negative impact on patients and society. Recent literature suggests that successful programs to improve adherence should include a combination of strategies. The new technologies represent a promising tool to improve adherence.
