Asthma control and quality of life in adolescents: The role of illness perceptions, medication beliefs, and adherence

The concept of treatment beliefs in children and adolescents with chronic health conditions: a scoping review

Children and adolescents with chronic health conditions are faced with ongoing challenges, making self-regulation crucial. As children grow up, they gradually develop differentiated beliefs about illness and treatment. While research indicates treatment beliefs as relevant factor on outcomes like adherence, the specific contents and dimensions of children's and adolescents' treatment beliefs remained unclear. This scoping review therefore aimed at the identification of treatment beliefs dimensions in children and adolescents with chronic health conditions, the underlying theoretical frameworks, and methodological operationalisation. Published literature was examined by applying systematic searches in electronic databases (Medline, PsycINFO, CINAHL) and comprehensive selection criteria, resulting in 49 included studies. The predominant treatment beliefs dimensions were necessity, concerns, perceived benefits and costs/barriers, and expectations. The latter can be differentiated into outcome, social, process, and structural expectations, and expectations of one's own role in the treatment process. In addition, dimensions that cover emotions and reasons for treatment were identified. The results are related to the methods and theoretical models applied, which were often adapted from adult research. However, additional and possibly more child-specific dimensions such as social expectations and emotions were found. This scoping review indicates several research gaps and discusses practical implications.

Parent and Youth Athlete Perceptions of Concussion Injury: Establishing a Factor Structure

OBJECTIVE

The first objective was to establish the respective factor structures of a concussion perceptions inventory that was adapted for youth athletes (ages 8-14 years) and their parents from the Perceptions of Concussion Inventory for Athletes. The second objective was to understand the associations between the concussion perceptions of youth athlete-parent dyads.

METHOD

In this cross-sectional study, 329 parent-youth athlete dyads completed a respective concussion perception inventory. Mean age of youth respondents was 10.9 ± 1.8 years (70.1% male) and mean age of parent respondents was 40.5 ± 13.6 years (60.9% female).

RESULTS

Exploratory factor analyses revealed unique 7-factor structures for both the youth athlete and parent inventories (youth athlete: anxiety, clarity, treatment, permanent injury, symptom variability, long-term outcomes, and personal control; parent: anxiety, clarity, treatment, permanent injury, symptom variability, and long-term outcomes, and affect others). Weak associations were found between dyads on the 5 factors that were composed of identical items (anxiety, clarity, treatment, permanent injury, and symptom variability).

CONCLUSIONS

Findings suggest that this adapted inventory has adequate psychometric properties to be used in the study of the concussion perceptions of youth athletes and their parents. Weak correlations across the concussion perceptions in the dyads suggest that parents and children hold different concussion perceptions and this should be considered in instrument selection of future studies.

The rehabilitation treatment beliefs questionnaire-revised: assessing adolescents' treatment beliefs

OBJECTIVE

While there are several studies on children's and adolescents' beliefs about illness and medication treatment, there is limited research on their treatment beliefs in the context of rehabilitation. The Rehabilitation Treatment Beliefs Questionnaire (RTBQ) was the first instrument available to assess pediatric patients' rehabilitation-related treatment beliefs. However, the RTBQ had some limitations that we aimed to address in this study: We revised the content of the RTBQ to include previously unaddressed dimensions of rehabilitation-related treatment beliefs, and we thoroughly tested its psychometric properties based on a sizeable, multicenter sample of adolescents with different chronic diseases.

METHODS

Across 11 pediatric rehabilitation clinics throughout Germany, eligible patients aged 12-18 years with any chronic physical or mental health condition were invited to participate in an online survey. Psychometric evaluation included item analysis, exploratory factor analysis, internal consistency and construct validity.

RESULTS

The sample comprised N = 294 adolescents (M = 14.2 years) with various chronic conditions. Psychometric testing demonstrated a coherent factor structure with 6 interpretable scales covering process and outcome expectations, expectations of one's own role in the treatment process, structural expectations, concerns, and emotions, the latter three representing previously unaddressed dimensions of rehabilitation-related treatment beliefs. Internal consistency was acceptable to good. Construct validity analyses showed mostly hypotheses-consistent correlations with related constructs.

CONCLUSIONS

The revised RTBQ provides a psychometrically well-tested, adolescent-specific, and disease-generic instrument that captures multiple dimensions of rehabilitation-related treatment beliefs. Practical implications include identifying adolescents' beliefs about rehabilitation treatment in order to actively involve them in their illness management.

Illness perception: A bibliometric study

Illness perception is a crucial area of study that has seen significant growth and development over the years. This study conducts a comprehensive bibliometric and network analysis of illness perception research, capturing its evolution from 1975 to 2023. Utilizing 1813 publications from the Scopus database, authored by 5428 researchers, we identify key scholars and influential articles in the field. Our analysis includes various bibliometric networks such as citation, co-citation, collaboration, and keyword co-occurrence networks, along with the presentation of intellectual structure maps. Major research areas include the role of illness perception in mental health conditions like depression, coping mechanisms, quality of life, and chronic illnesses like diabetes, as well as the influence of lay beliefs on health behaviors, and the impact of illness beliefs on conditions like Myocardial Infarction and stroke. The results show a growing academic interest in understanding how illness perceptions shape healthcare outcomes and behaviors.

Parents' Beliefs about Medicines and Their Influence on Inhaled Corticosteroid Adherence in Children with Asthma

The most widespread chronic condition observed amid children globally is asthma. Only half of children with asthma adhere to their prescribed inhaled corticosteroids (ICS) therapy. Parents' emotions and perspectives regarding asthma have an impact on inhalation corticosteroid adherence. The participants in this study were 148 parents of children with asthma, with the aim to redintegrate their beliefs about medicines in general and specifically of ICS and the impact on ICS adherence in children with asthma. Children were mostly male (66.9%), older than five years (58.8%), parents were female, mean age 38, employed, and with a history of consumption of some form of corticosteroids. Parents' answers show that 50% of them disagreed with the statement that medicines are addictive, and 90% agree that medicine helps many to live better. A percentage of 77.7% of parents acknowledge that their child's health relies on inhaled corticosteroids (ICS), and 86.5% of parents agree that these medications safeguard their child from worsening health. Most of the parents (93.2%) adhere to the guidelines and instructions of the doctor. In summary, parents who hold the belief that medicines are neither overused nor harmful tend to exhibit a higher adherence. Furthermore, those with elevated adherence levels express lower levels of concern regarding the use of inhaled corticosteroids (ICS) in their children's asthma therapy.

Beliefs about antiretroviral therapy and their association with adherence in young people living with perinatal HIV in England: a cross-sectional analysis

This cross-sectional analysis aimed to describe beliefs about antiretroviral therapy (ART) in young people living with perinatal HIV (PHIV) in England, and the association between these beliefs and adherence to ART. The Beliefs About Medicine Questionnaire (Highly Active Antiretroviral Therapy version), was used to measure participants' beliefs in the necessity of ("Necessity score") and concerns regarding ("Concerns score") ART. Participants were classified as having high/low total scores using midpoints of the score scales. Associations between beliefs and being Last Month Adherent (LMA; self-reported not missing more than 2 consecutive ART doses in the month prior to the interview) were analysed using logistic regression, adjusting for sociodemographic, clinical, and psychosocial variables. Of 247 PHIV (median age = 18.6 years), 158 (64%) were LMA. 224 (91%) had a high Necessity score and 54 (22%) a high Concerns score. There was no association between high Necessity score and LMA in multivariable analysis (adjusted odds ratio (aOR) = 1.34, 95% confidence interval (CI) = 0.34-5.28, p = 0.679); however, high Concerns score was independently associated with a reduced odds of being LMA (aOR = 0.19, CI = 0.07-0.47, p < 0.001). Interventions to address the concerns young people living with PHIV have about ART should be explored as a strategy to improve their adherence.

Dupilumab leads to better-controlled asthma and quality of life in children: the VOYAGE study

BACKGROUND

Dupilumab has shown long-term treatment benefits in children with uncontrolled asthma. We assessed in more detail the impact of dupilumab on asthma control and health-related quality of life (HRQoL) in children and their caregivers.

METHODS

Children aged 6-11 years with uncontrolled moderate-to-severe type 2 asthma (baseline blood eosinophils ≥150 cells·µL-1 or fractional exhaled nitric oxide ≥20 ppb; n=350) were treated with dupilumab or placebo for 52 weeks in the VOYAGE study. Primary outcomes of these analyses were asthma control (change from baseline in Asthma Control Questionnaire 7 Interviewer-Administered (ACQ-7-IA) and achieving a clinically meaningful response of ≥0.5 points); proportion of patients achieving well-controlled asthma or better (ACQ-7-IA ≤0.75 points); effect on patients' (Standardised Paediatric Asthma Quality of Life Questionnaire Interviewer-Administered (PAQLQ(S)-IA)) and caregivers' (Paediatric Asthma Caregiver's Quality of Life Questionnaire (PACQLQ)) HRQoL; and allergic rhinitis-related QoL.

RESULTS

Dupilumab versus placebo significantly improved children's ACQ-7-IA scores by week 4 with sustained improvements through week 52 (least squares mean difference at week 52: -0.44, 95% CI -0.59- -0.30; p<0.0001); a higher proportion achieved a clinically meaningful response (week 52: 86% versus 75%; p=0.0051). At weeks 24 and 52, more children who received dupilumab achieved well-controlled asthma (ACQ-7-IA ≤0.75 points: 61% versus 43%; p=0.0001 and 70% versus 46%; p<0.0001, respectively). Significant improvements in PAQLQ(S)-IA and PACQLQ scores were observed by week 52.

CONCLUSIONS

In children aged 6-11 years with moderate-to-severe type 2 asthma, dupilumab treatment was associated with rapid, sustained improvements in asthma control. HRQoL was significantly improved for children and their caregivers.

The impact of childhood glaucoma on psychosocial functioning and quality of life: a review of the literature

We present a novel comprehensive literature review of studies of the psychosocial functioning (PF) and quality of life (QoL) of patients with childhood glaucoma and their caregivers. Our findings demonstrate variable study quality and approach, as well as inconsistent results relating to the association of glaucoma-specific factors and sociodemographic variables with measured PF and QoL. Future studies should focus on the development of culturally cognizant and standardized assessment tools, execution of multi-center longitudinal studies with global representation, evaluation of PF and QoL among siblings and childhood glaucoma providers, and implementation of interventions to improve patient and caregiver PF and QoL.

Causal relationships among self-management behaviors, symptom control, health-related quality of life and the influencing factors among Thai adolescents with asthma

Objective

To examine causal relationships among asthma self-management behaviors, asthma symptom control, health-related quality of life and the influencing factors among Thai adolescents.

Methods

A cross-sectional study was conducted using convenience sampling. A total of 240 adolescent-caregiver dyads from three tertiary hospitals in Bangkok, Thailand was ultimately included. Interviews and self-administered questionnaires assessing health-related quality of life, asthma symptom control, asthma self-management behaviors, health literacy, depression, comorbidities, family support, peer support, home environmental management, and relationships with health care providers were administered between November 2020 and July 2021. A hypothesized model based on the revised self- and family-management framework was proposed. Data were analyzed using descriptive statistics and path analysis.

Results

It was shown that the proposed model was a good fit for the empirical data and accounted for 67.2% of the variance in health-related quality of life. Depression and asthma symptom control directly affected quality of life (β = -0.132, P < 0.05; and β = 0.740, P < 0.05, respectively), while asthma self-management behaviors did not. Both depression and asthma self-management behaviors had indirect effects on the quality of life through asthma symptom control (β = -0.382, P < 0.05; and β = 0.225, P < 0.05, respectively). Health literacy (β = 0.343, P < 0.05), family support (β = 0.167, P < 0.05), peer support (β = 0.163, P < 0.05), and relationships with health care providers (β = 0.181, P < 0.05) also showed direct effects on asthma self-management behaviors.

Conclusion

The findings confirmed the causal relationships among asthma symptom control, self-management behaviors, depression and health-related quality of life. Health literacy, support from family and peers, and relationships with health care providers were also found to influence asthma self-management behaviors. To achieve effective asthma control and good quality of life, a nursing intervention promoting asthma self-management for Thai adolescents should be developed. Early detection and intervention of depressive symptoms are also suggested.

Illness perception and treatment adherence in haemodialysis: a systematic review

Patients with kidney failure need lifelong renal replacement therapy to survive and, worldwide, in-centre haemodialysis is the most common modality. The efficacy of this treatment largely depends on the patients' adherence to several health behaviours. According to Leventhal's self-regulation model, patients' illness perceptions can be a key factor for treatment adherence. Therefore, it is of utmost importance to better understand this relationship to further fine-tune the effectiveness of renal rehabilitation programs. This study aimed to systematically review the literature on the association between illness perceptions and treatment adherence in adults undergoing in-centre haemodialysis. The search was performed on PubMed, Scopus, CINAHL, Web of Science (all databases included), and ProQuest (all databases included), from the 17th to the 21st of December 2020. The last update was performed on the 9th of June of 2022. Articles were critically appraised using the Joanna Briggs Institute (JBI) Critical Appraisal Checklists for Analytical Cross-Sectional Studies. Nine studies were included comprising a total of 1161 patients undergoing in-centre haemodialysis. Associations between illness perceptions and treatment adherence were found in six studies. Adherence to dietary restrictions was the type of adherence with more significant associations with illness perceptions, followed by fluid control and medication intake. Two studies combining several types of adherences into an overall score also showed significant associations with illness perceptions. No significant associations were found between illness perceptions and adherence to dialysis sessions. These findings suggest that illness perceptions in patients undergoing in-centre haemodialysis should continue to receive research attention. Future interventions should acknowledge the importance of modifying maladaptive illness perceptions to improve treatment adherence in kidney failure. The protocol for this systematic review was registered on PROSPERO (CRD42021231929).

Appropriate inhaler use in children with asthma: barriers and opportunities through the lens of the socio-ecological model

Objective: Proper use of inhaled medications is essential for management of asthma, as inhaled therapies are recommended as first-line for both prevention and treatment of asthma symptoms. Optimizing adherence requires identifying and understanding multiple layers of systemic complexity to obtaining and using these therapies and offering specific solutions to address these barriers. Bronfenbrenner's socio-ecological model provides a framework for examining multilevel systems - both internal and external - that contribute to the management of childhood asthma. The four levels in this model consist of factors related to the individual, interpersonal relationships, organizational entities, and societal structures and rules. This narrative review identifies influences and factors related to asthma inhaler adherence by each level and offers evidence-based solutions to each obstacle.Data Sources: We conducted PubMed searches to identify relevant articles for barriers and solutions impacting asthma control at each level of the socio-ecological model.Study Selection: Common barriers to asthma control at each model level were identified. Pertinent studies for each barrier were identified and reviewed by the writing group for inclusion into the narrative review.Results: For each level of the socio-ecological model, three primary issues were identified based on the literature review. Approaches for addressing each issue in an evidence-based, systematic fashion are presented.Conclusion: Understanding the obstacles and potential interventions to achieve proper use of inhaled medications is a critical step necessary to develop and implement systematic solutions aimed at improving asthma control and morbidity for the more than 6 million affected children in the United States.

Assessing the Impact of Health Education Intervention on Asthma Knowledge, Attitudes, and Practices: A Cross-Sectional Study in Erbil, Iraq

Asthma causes chronic coughing, wheezing, dyspnea, and chest pressure. This study assessed asthmatic patients' knowledge, attitudes, and practice (KAP) of bronchial asthma and proper education on its meaning, risk factors, symptoms, diagnosis, management, and prevention practices. We performed a cross-sectional interventional asthma KAP survey in Erbil, Iraq. We adapted a validated study questionnaire from KAP studies in other nations to the Erbil situation and culture. In Erbil, Kurdistan, Iraq, two major hospitals' asthma clinics were studied. We chose 250 asthmatic patients from October 2018 to July 2019. Health education was comprehensive. The health education program used a Kurdish PowerPoint with a printout. Twenty-five groups received two weeks of one-hour health education pre-intervention. Each group was questioned before, 2 weeks after, and 12 weeks after health education. All data were analyzed by SPSS v26. The mean age of the respondents was 37.52 ± 15.16, with 48.7% of the respondents having a positive family history of asthma. After 2 weeks of health education intervention, respondents had a higher knowledge score and positive attitudes compared to pre-education, and after 12 weeks of education, there was a significant difference (p < 0.001) with improvised prevention practice. Health education programs led to considerable improvements in asthmatic patients' knowledge, attitudes, and practices regarding their condition. After receiving health education for a period of two weeks, the majority of the participants answered correctly regarding asthma, its causes, and the elements that trigger asthma attacks.

Effect of illness perceptions on asthma control and quality of life amongst adult outpatients with asthma in China

OBJECTIVE

To investigated the influence of illness perceptions and other risk factors related to poor asthma control and quality of life in adult outpatients with asthma in China.

METHODS

Patients with a confirmed asthma diagnosis were recruited from the outpatient clinic at Zhongshan Hospital, Fudan University in Shanghai. Sociodemographic, psychological, and asthma related variables were assessed in all participants. Patients' illness perceptions, medication adherence, asthma control, and quality of life were assessed using validated questionnaires, such as the Brief Illness Perception Questionnaire, Medication Adherence Rating Scale (MARS-A), the Asthma Control Test, and the Mini Asthma Quality of Life Questionnaire. Multiple linear regressions and logistic regressions were used to examine the associations between illness perceptions, medication adherence behaviors, and disease outcome (i.e., asthma control and quality of life).

RESULTS

A total of two hundred thirty-one (231) outpatients with asthma were included in this cross-sectional study, 80 of whom (34.6%) had asthma that was uncontrolled. Patients who perceived their life (β = - 0.197, p < 0.001) and emotions (β = - 0.294, p < 0.001) as severely affected by the illness were more likely to have a lower quality of life, findings that were statistically significant. Also, patients who believed they had a higher degree of personal control over their illness (β = 0.333, p < 0.001), and had better medication adherence (β = 0.250, p < 0.001) were found to have a better quality of life.

CONCLUSION

Our study indicated that illness perceptions and medication adherence have a significant impact on disease outcome. Both of these factors should be considered when determining the best health care practices or constructing a predictive intervention model for patients with uncontrolled asthma.

Health-related quality of life decreases in young people with asthma during the transition from adolescence to young adulthood: a birth cohort study

BACKGROUND

During the transition from paediatric to adult healthcare there is a gap between asthma guidelines and actual management with decreased healthcare consultations and dispensations of asthma medications after the transition to adult healthcare among young people with asthma. How health-related quality of life (HRQoL) develops during the transition from adolescence to young adulthood is unclear. Our aim was therefore to investigate HRQoL among young people with asthma during the transition to adulthood. Further, to assess if level of asthma control and physical activity influence any potential association between asthma and HRQoL.

METHODS

The study population consisted of 2268 participants from the ongoing Swedish population-based prospective birth cohort BAMSE (Barn/Child, Allergy, Milieu, Stockholm, Epidemiology). HRQoL was measured using the instrument EQ-5D-3 L and three general questions. The EQ-5D-3 L consists of the EQ-5D descriptive system and the EQ visual analogue scale (EQ VAS). The EQ-5D-3 L instrument and questions on general health, symptoms and treatment of asthma, and lifestyle factors were based on data from follow-ups at 16 and 24 years. Cross-sectional analyses were made.

RESULTS

At the 24-year follow-up, the adjusted median values of EQ VAS were lower compared with at the 16-year follow-up; among both participants with asthma (80 vs. 85, p < 0.01) and those without asthma (80 vs. 87, p < 0.01). At the 24-year follow-up, participants with uncontrolled asthma had a lower adjusted median EQ VAS score than peers with controlled/partly controlled asthma (75 vs. 80, p = 0.03). Further, young adults with asthma who did not fulfil the WHO recommendations on physical activity had lower EQ VAS scores than peers who did (70 vs. 80, p < 0.01).

CONCLUSION

HRQoL is lower in young adulthood than in adolescence. Young adults with asthma having uncontrolled disease or who are physically inactive appear to be particularly vulnerable.

Association between illness perception and clinical control, quality of life, physical activity, and psychosocial status in subjects with moderate to severe asthma: a cluster analysis

Background: Illness perception (IP) is a psychosocial factor involved in several chronic diseases and is associated with relevant clinical outcomes. However, the relationship between IP and health-related quality of life (HRQoL), psychosocial status, and physical activity in daily life (PADL) in subjects with asthma is poorly understood.Objective: To identify groups of subjects with asthma based on their IPs and to assess their association with clinical control, HRQoL, psychosocial disturbances, and PADL.Methods: This cross-sectional study included 149 subjects with moderate to severe asthma. IP, anthropometric data, Asthma Control Questionnaire-7, Asthma Quality of Life Questionnaire, Hospital Anxiety and Depression Scale, PADL (accelerometry), and general self-efficacy (GSE) were assessed. Cluster analysis was performed to identify clusters with similar profiles and investigate their characteristics and differences. Pearson's correlation coefficient was used to test the associations between IP and other variables.Results: Statistical analyses identified two clusters of subjects with asthma based on IP. Cluster 1 presented worse IP in seven out of eight domains than Cluster 2. Cluster 1 had more negative consequences of the disease, worse understanding, and a high emotional representation of the disease than Cluster 2. Cluster 1 also had a greater extent of asthma symptoms, poor clinical control, worse HRQoL, and more symptoms of anxiety and depression. No difference between clusters was found for PADL or self-efficacy.Conclusion: Subjects with asthma who have worse IP have more negative symptoms, worse clinical control, HRQoL, and symptoms of anxiety and depression.

Control of Allergic Rhinitis and Asthma Test: A systematic review of measurement properties and COSMIN analysis

The Control of Allergic Rhinitis and Asthma Test (CARAT) is a patient-reported outcome measurement (PROM) assessing the control of asthma and allergic rhinitis (AR) at a 4 week interval. This systematic review aimed to evaluate the measurement properties of CARAT. Following PRISMA and COSMIN guidelines, we searched five bibliographic databases and retrieved studies concerning the development, assessment of properties, validation, and/or cultural adaption of CARAT. The studies' methodological quality, the quality of measurement properties, and the overall quality of evidence were assessed. We performed meta-analysis of CARAT measurement properties. We included 16 studies. Control of Allergic Rhinitis and Asthma Test displayed sufficient content validity and very good consistency (meta-analytical Cronbach alpha = 0.83; 95% CI = 0.80-0.86;I²  = 62.6%). Control of allergic rhinitis and Asthma Test meta-analytical intraclass correlation coefficient was 0.91 (95% CI = 0.64-0.98;I²  = 93.7%). It presented good construct validity, especially for correlations with Patient-reported outcome measures assessing asthma (absolute Spearman correlation coefficients range = 0.67-0.73; moderate quality of evidence), and good responsiveness. Its minimal important difference is 3.5. Overall, CARAT has good internal consistency, reliability, construct validity and responsiveness, despite the heterogeneous quality of evidence. Control of Allergic Rhinitis and Asthma Test can be used to assess the control of asthma and AR. As first of its kind, this meta-analysis of CARAT measurement properties sets a stronger level of evidence for asthma and/or AR control questionnaires.

Level of asthma control and its determinants among adults living with asthma attending selected public hospitals in northwestern, Ethiopia: using an ordinal logistic regression model

Background

Asthma is a major public health challenge and is characterized by recurrent attacks of breathlessness and wheezing that vary in severity and frequency from person to person. Asthma control is an important measure of health outcomes of the patients with asthma and reflecting the impact of an illness and its treatment from the patient’s perspective. Therefore, this study assessed the asthma control levels and their determinants among adults living with asthma in selected public referral hospitals in northwestern Ethiopia.

Materials and method

A multicenter institutional-based cross-sectional study was conducted in North-western Ethiopia, from October to December 2021. A systematic random sampling technique was employed to recruit the study participants. Bi-variable and multivariable ordinal logistic regression was used to determine the independent predictors of asthma control levels. A p-value of < 0.05 was considered as statistically significant.

Result

A total of 409 patients were included in the final analysis. Asthma was controlled by 28.9% with 95%CI (24.7, 33.5) people who have asthma. Regarding the potential predictor of asthma control level, being male (AOR = 6.5, 95%CI (1.28, 32.44), Married (AOR = 3.62, 95%CI (1.28, 10.27), healthcare provider adherence to guideline usage (AOR = 8.4,95%CI (2.7, 26) and non-fuel users (AOR = 6.0, 95%CI (1.5, 22.5) were variables that increase asthma control. However, non-adherent to medication (AOR = 0.16, 95%CI (0.059, 0.48), low level of patient enablement (AOR = 0.19, (95%CI) (0.08, 0.49) and poor relationship with healthcare provider (AOR = 0.024,95%CI (0.02, 0.23) were variables that significantly decreased asthma control level.

Conclusion

The findings indicated that asthma control remains suboptimal in a large proportion of patients with asthma in the study setting. Socio-demographic, clinical, healthcare-related, and medication-related variables were significantly associated with asthma control. Therefore, our study highlights multifaceted interventions, including comprehensive asthma education along with an integrated treatment plan to improve asthma control and quality of life.

Effects of an Asthma Education Camp Program on Quality of Life and Asthma Control among Thai Children with Asthma: A Quasi-Experimental Study

Caregiver knowledge and management ability can improve asthma control and quality of life (QoL) among children with asthma. A quasi-experimental study was proposed to assess the effect of a 1 day educational camp program on the QoL of children with asthma and on their caregivers’ asthma knowledge and management. Children with asthma and their caregivers were invited to attend a camp. The Pediatric Asthma Quality of Life Questionnaire (PAQLQ), Childhood Asthma Control Test score, and forced expiratory volume in 1 s were assessed in children at the first, 3 month, 6 month, and 1 year visits. The caregiver’s knowledge, attitudes, and practice (KAP) survey was assessed at each visit. A total of 212 patients were enrolled (mean age: 8.56 ± 1.63 years) but only 72 patients attended the camp. There was no significant difference in baseline characteristics, asthma severity, or asthma risk factors between camp attendees and non-attendees. The KAP of caregivers who attended the camp was significantly higher than non-attendees at the 3 month and 6 month visits (16.86 ± 2.3 vs. 15.95 ± 2.78 (p = 0.009); 17.25 ± 2.22 vs. 16.7 ± 2.68 (p = 0.04)). QoL did not significantly differ between patient attendees vs. non-attendees. PAQLQ mean score correlated with asthma control, indicating that patients with well-controlled asthma had better QoL than those with unstable asthma control (p < 0.001). An asthma education camp can help increase self-management knowledge, even though its effect may be short-term. Integrating asthma education into routine care could enhance asthma management in children.

Improving Asthma Care Together (IMPACT) mobile health intervention for school-age children with asthma and their parents: a pilot randomised controlled trial study protocol

INTRODUCTION

Asthma is an incurable, lifelong condition that places children at increased risk for exacerbation, hospitalisation and school absences. Most paediatric asthma interventions target parents alone and are overly prescriptive. Improving Asthma Care Together (IMPACT) is a novel shared management system comprised of a mobile health (mHealth) application, symptom watch and tailored health intervention that pairs parent and child together as an asthma management team. IMPACT helps families monitor asthma status, tailor asthma management strategies and facilitate intentional transition of asthma management to the child. The purpose of this study is to determine the feasibility, acceptability and preliminary efficacy of the IMPACT intervention.

METHODS AND ANALYSIS

This pilot randomised controlled trial will recruit 60 children with asthma (7-11 years) and one parent. All parent-child dyads will complete data collection sessions at baseline, postintervention and follow-up. Dyads randomised to the intervention group (IMPACT) will complete the 8-week intervention comprised of weekly activities including symptom monitoring, goal setting and progress monitoring. Dyads randomised to the control group will receive usual care but then be provided access to IMPACT at the end of the study. Feasibility will be measured by the proportion of eligible dyads enrolled and retained. Acceptability of IMPACT will be assessed using the Acceptability of Intervention Measure, the System Usability Scale and a semistructured interview. Preliminary efficacy is determined based on change in primary outcomes, parent-reported and child-reported asthma responsibility and asthma self-efficacy scores, from baseline.

ETHICS AND DISSEMINATION

This study has been approved by the University of Washington Institutional Review Board; study ID: STUDY00010461. Participants gave informed consent to participate in the study before taking part. Study results will be disseminated in peer-reviewed journals and scientific conferences. A lay summary will be provided to study participants.

Characteristics and outcomes associated with two asthma quality of care measures

OBJECTIVE

We investigated asthma quality measures to understand patient characteristics associated with non-attainment of quality care and measure the association with asthma-related emergency department (ED) visits or inpatient hospitalizations (IPs).

METHODS

Using administrative data from ALL Kids, Alabama's Children's Health Insurance Program, from 2013 to 2019 we calculated non-attainment of the Medication Management for Asthma (MMA) and Asthma Medication Ratio (AMR) quality measures. Patient characteristics and asthma-related ED visits and IPs associated with non-attainment of the MMA and AMR measures were assessed using logit regression models and Marginal effects at the mean.

RESULTS

Among 2528 children with asthma, 53.2% failed to attain the MMA measure and 8.5% the AMR measure. Prior asthma-related ED visits or IP stays increased likelihood of non-attainment by 14.8 percentage points (95% CI 8.6-20.9) for MMA and 7.3 percentage points (95% CI 2.8-11.8) for AMR. Among 868 children (34.3%) with three years of continuous enrollment, AMR non-attainment was associated with a 6.1 percentage point increase in ED or IP utilization (95% CI 1.3-10.9), however MMA non-attainment was not associated with either outcome. Prior ED visit/IP stay was associated with a 17.2 percentage point (95% CI 8.3-26.1) increase in the likelihood of a subsequent ED visit/IP stay among those with non-attainment MMA and a 15.5 percentage point increase (95% CI 6.9-24.2) for non-attainment AMR.

CONCLUSIONS

Patient characteristics associated with non-attainment of asthma quality measures presents actionable evidence to guide improvement efforts as non-attainment AMR increases the risk of subsequent ED visits and IP stays.

Electronic reminders and rewards to improve adherence to inhaled asthma treatment in adolescents: a non-randomised feasibility study in tertiary care

OBJECTIVE

To test the feasibility and acceptability of a short-term reminder and incentives intervention in adolescents with low adherence to asthma medications.

METHODS

Mixed-methods feasibility study in a tertiary care clinic. Adolescents recruited to a 24-week programme with three 8-weekly visits, receiving electronic reminders to prompt inhaled corticosteroid (ICS) inhalation through a mobile app coupled with electronic monitoring devices (EMD). From the second visit, monetary incentives based on adherence of ICS inhalation: £1 per dose, maximum £2 /day, up to £112/study, collected as gift cards at the third visit. End of study interviews and questionnaires assessing perceptions of asthma and ICS, analysed using the Perceptions and Practicalities Framework.

PARTICIPANTS

Adolescents (11-18 years) with documented low ICS adherence (<80% by EMD), and poor asthma control at the first clinic visit.

RESULTS

10 out of 12 adolescents approached were recruited (7 males, 3 females, 12-16 years). Eight participants provided adherence measures up to the fourth visits and received rewards. Mean study duration was 281 days, with 7/10 participants unable to attend their fourth visit due to COVID-19 lockdown. Only 3/10 participants managed to pair the app/EMD up to the fourth visit, which was associated with improved ICS adherence (from 0.51, SD 0.07 to 0.86, SD 0.05). Adherence did not change in adolescents unable to pair the app/EMD. The intervention was acceptable to participants and parents/guardians. Exit interviews showed that participants welcomed reminders and incentives, though expressed frustration with app/EMD technological difficulties. Participants stated the intervention helped through reminding ICS doses, promoting self-monitoring and increasing motivation to take inhalers.

CONCLUSIONS

An intervention using electronic reminders and incentives through an app coupled with an EMD was feasible and acceptable to adolescents with asthma. A pilot randomised controlled trial is warranted to better estimate the effect size on adherence, with improved technical support for the EMD.

Real-life isoniazid and rifampicin plasma concentrations in children: a tool for therapeutic drug monitoring of tuberculosis

Background

Low plasma levels of first-line antitubercular drugs can be counted among the main causes of poor response to antitubercular therapy, and therapeutic drug monitoring has been proposed as a method to promote tailored treatments for both child and adult patients. The main aim of the study was to evaluate serum concentrations of isoniazid (INH) and rifampicin (RIF) and to investigate reasons for sub-therapeutic plasma concentrations in order to fix dosages.

Methods

Children with TB were prospectively enrolled from January to August 2019. Two venous blood samples were collected (the first at least 15 days after the beginning of antitubercular treatment, and the second between 1 and 8 weeks later). Plasma concentrations were determined by a validated high-performance liquid chromatography method.

Results

In all, 45 children were included. Seventy blood samples for INH plasma concentration were collected between 120 and 240 min after drug intake. Adjusting for dose (mg/kg/day) and time of INH administration, when considering three different age groups (≤ 2 years, 2–12 years, > 12 years), a statistically significant lower INH plasma concentration was observed in younger children compared to the older age groups in the multivariate analysis (p < 0.001 and p < 0.001). A total of 68 blood samples were evaluated for RIF concentrations. Both for INH and RIF a statistically significant lower plasma concentration was also observed in adolescents (p < 0.001). Fifteen children (15/45, 33%) presented drug concentrations under the referral therapeutic range.

Conclusions

Based on our findings, monitoring patients’ drug plasma concentrations in children under 2 years of age and in adolescents can make treatment more patient-tailored.

Medication adherence in adult Chinese patients with asthma: role of illness perceptions and medication beliefs

OBJECTIVE

This study aimed to investigate the relationship between illness perceptions, medication beliefs, and self-reported adherence to inhaled corticosteroid (ICS) therapy in adult Chinese patients with asthma.

METHODS

A cross-sectional survey was conducted in the asthma outpatient clinic of Zhongshan Hospital, Fudan University (Shanghai, China) between October 2018 and September 2019. Illness perceptions, medication beliefs, and medication adherence were assessed using validated scales, specifically the Medication Adherence Report Scale for Asthma, Beliefs about Medicines Questionnaire -Specific, and the Brief Illness Perception Questionnaire. Spearman correlation and multiple logistic regression were used to determine the relationship among these factors. Results: A total of 234 patients were included in this study. Of this group, 99 (42.3%) participants were non-adherent to their ICS medication. Medication adherence correlated negatively with 'illness identity' (perceived symptom), 'emotional response' (perceived emotional effect) and concerns about medication (r=-0.16, -0.16 and -0.15, respectively, p < 0.05). After adjusting for illness perceptions, medication beliefs and demographics, beliefs about the necessity of medication (odds ratio [OR]: 1.14, 95% confidence interval [CI]: 1.01-1.30), and emotional response to the disease (OR: 0.89, 95% CI: 0.80-0.99) were significantly associated with medication adherence in patients with asthma.

CONCLUSION

Beliefs about the necessity of medication and emotional response to the illness have a strong influence on self-reported medication adherence in adult patients with asthma in China. Interventions targeted adherence improvement among patients with asthma may be tailored to the individual's baseline perceptions and medication beliefs, and focus on modifying inaccurate illness perceptions and medication beliefs as the main targets.

Efficacy and Safety of As-Needed Budesonide-Formoterol in Adolescents with Mild Asthma

BACKGROUND

Medication adherence is challenging for adolescents. In mild asthma, as-needed budesonide-formoterol (BUD-FORM) reduces severe exacerbations compared with as-needed short-acting beta₂-agonists, similar to the reduction with maintenance budesonide.

OBJECTIVE

This post hoc pooled analysis of Symbicort Given as-needed in Mild Asthma (SYGMA) 1 and 2 assessed the efficacy and safety of as-needed BUD-FORM in adolescents.

METHODS

SYGMA 1 and 2 were 52-week, double-blind studies (NCT022149199; NCT02224157) in patients 12 years or older with mild asthma. Patients were randomized to twice-daily placebo + as-needed BUD-FORM 200/6 μg, twice-daily BUD 200 μg + as-needed terbutaline (BUD maintenance), or twice-daily placebo + as-needed terbutaline 0.5 mg (SYGMA 1 only). Annualized severe exacerbation rates, maintenance treatment adherence, and safety (including change in height) were compared between treatment groups in adolescents (aged ≥12 to <18 years).

RESULTS

Severe exacerbation rate was similar with as-needed BUD-FORM and BUD maintenance (pooled analysis: 0.08 vs 0.07/y; P = .634), and was significantly lower with as-needed BUD-FORM versus as-needed terbutaline (SYGMA 1: 0.04 vs 0.17/y; P = .005). Median adherence was 73% in SYGMA 1 and 51% in SYGMA 2. Change in height from baseline in adolescents aged ≥12 years to <14 years was significantly greater with as-needed BUD-FORM (4.8 cm) versus BUD maintenance (3.9 cm) (pooled: P < .046), and was similar between as-needed BUD-FORM (4.5 cm) and as-needed terbutaline (4.1 cm) (SYGMA 1: P = .500). No new or unexpected safety concerns were identified.

CONCLUSIONS

In adolescents with mild asthma, as-needed BUD-FORM was superior to as-needed terbutaline for severe exacerbation reduction, with similar efficacy to BUD maintenance. As-needed BUD-FORM provides an alternative treatment option for adolescents with mild asthma, without needing daily treatment.

Psychological burden of asthma in adolescents and their parents

INTRODUCTION

Asthma, a common chronic disease in adolescents is impacted by factors affecting quality of life. This study aimed to determine the psychosocial factors of adolescents with asthma and their parents.

METHODS

The study included 122 adolescents with asthma, 82 healthy controls, and their parents who completed the Asthma Control Test (ACT), Pediatric Asthma Quality of Life Questionnaire (PAQLQ) and the Brief Symptom Inventory (BSI).

RESULTS

The mean age was 14.2 ± 1.9 years. ACT score was high and depression was low in patients with good treatment compliance. As the age of the first asthma symptoms/diagnosis increased, somatization, anxiety, hostility and general psychopathology scores increased, as did the somatization score of parents. Parental anxiety score was not related with adolescent BSI scores in the controls but in the study group when it was higher, the anxiety, depression, somatization, and general psychopathology scores were higher. PAQLQ showed that anxiety, negative self-esteem, somatization, depression, and general psychopathology were higher in patients concerned about asthma. Depression and somatization scores were higher in the parents of patients who perceived that "Treatment does not contribute to asthma control." Somatization scores were higher among parents of patients who noted: "Asthma will not pass in the long-term" and "I cannot control asthma."

CONCLUSION

Higher scores of asthma patients who were anxious about the disease and families who were despondent about treatment demonstrate that health care providers should spend more time informing patients and caregivers. Increasing patient treatment compliance during early adolescence will lessen the psychological burden of the disease.

Long-term adherence to inhaled corticosteroids and asthma control in adult-onset asthma

BACKGROUND

In short-term studies, poor adherence to inhaled corticosteroids (ICS) has been associated with worse asthma control, but the association of long-term adherence and disease control remains unclear.

OBJECTIVE

To assess the relationship between 12-year adherence to ICS and asthma control in patients with adult-onset asthma.

METHODS

As part of the Seinäjoki Adult Asthma Study, 181 patients with clinically confirmed new-onset adult asthma and regular ICS medication were followed-up for 12 years. Adherence (%) to ICS was assessed individually ((µg dispensed/µg prescribed)×100) during the follow-up. Asthma control was evaluated after 12 years of treatment according to the Global Initiative for Asthma 2010 guideline.

RESULTS

Asthma was controlled in 31% and not controlled (partly controlled or uncontrolled) in 69% of the patients. Patients with not-controlled asthma were more often male, older, nonatopic and used higher doses of ICS than those with controlled disease. The mean±sd 12-year adherence to ICS was 63±38% in patients with controlled asthma and 76±40% in patients with not-controlled disease (p=0.042). Among patients with not-controlled asthma, those with lower 12-year adherence (<80%) had more rapid decline in forced expiratory volume in 1 s (-47 mL·year-1) compared to patients with better adherence (≥80%) (-40 mL·year-1) (p=0.024). In contrast, this relationship was not seen in patients with controlled asthma.

CONCLUSIONS

In adult-onset asthma, patients with not-controlled disease showed better 12-year adherence to ICS treatment than those with controlled asthma. In not-controlled disease, adherence <80% was associated with more rapid lung function decline, underscoring the importance of early recognition of such patients in routine clinical practice.

Application of mindfulness techniques in patients with asthma or COPD

OBJECTIVE

Mindfulness is the ability to pay attention to the present moment without judgment. Mindfulness interventions have proved to be effective in improving the management of psychological symptoms of chronic patients. The objective of this work is to update the evidence about the effects of mindfulness interventions on psychological symptoms in patients with asthma and chronic obstructive pulmonary disease (COPD).

METHODOLOGY

Data sources were PubMed and PsycInfo. From a first set of 109 articles, 12 about mindfulness-interventions in adult populations with asthma or COPD were finally included in the review.

RESULTS

Of the total of 12 studies included, 5 were qualitative and 6 quantitative (5 randomized controlled trials). One quantitative study reported long-term psychological effects in asthma patients, two studies reported short-term psychological effects in COPD patients. Relevant themes identified in qualitative studies included increased awareness, development of new relationships with dyspnea, including new cognitive strategies, and slowing down.

CONCLUSIONS

Mindfulness interventions could increase psychological resources in situations related to asthma and COPD symptoms. More randomized control trials are needed.
