Perceptions and experiences underlying self-management and reporting of symptoms in teens with asthma

Disseminating a health information website to teens using a three-pronged approach with social media outreach

Objective

To disseminate iuveo.org, a new health information website, primarily to teens in the United States using a three-pronged approach of social media, in-person, and emails.

Methods

Dissemination methods included a combination of in-person, email, and social media campaigns starting in August 2022 to reach teens and stakeholders focused on teen health. Following the Social Marketing Theory framework, a social media campaign was implemented utilizing Instagram and X (formerly Twitter). Website analytics, including monthly usage of iuveo, was measured utilizing Google Analytics. The intrinsic analytics from X and Instagram were also tracked.

Results

From August 2022-July 2023, iuveo attracted 1338 unique users to the website. In the same time frame, 1085 accounts were reached on Instagram, and 14,367 impressions were received on X. Most website users (84.8%) were classified as 'direct' acquisition, meaning that they directly typed in the URL or clicked on a link, and 7.3% of users visited iuveo from a social media platform.

Conclusion

A three-pronged dissemination strategy is beneficial when disseminating a new health information website.

Innovation

Utilizing a three-pronged approach with a social media campaign based on Social Marketing Theory, a health information website was disseminated to youth in the United States.

Optimisation of the quality of care for patients with severe asthma: ASfarMA project

 Severe asthma has an important impact on patients and healthcare resources. Recently, the new specific treatments have defined a new scenario in which person-focused care and specialist multidisciplinary teams are necessary. Our Severe Asthma Unit (SAU) started the ASfarMA project along with an external human-centered design company to understand patients' vision of their illness, treatment, and healthcare experience, and to define the ideal SAU by performing a core group session, in-depth semistructured interviews and co-creation workshop. Herein, a series of tips classified as either 'transformative solutions' or 'quick wins', according to a value versus effort matrix are presented. Successful implementation of the proposed solutions will be valuable for patients and healthcare professionals, optimising patient care and resources. These findings can also be helpful to other SAUs or other humanisation projects involving complex, chronic and multidisciplinary pathologies.

Children and young people's self-reported experiences of asthma and self-management nursing strategies: An integrative review

AIM

To explore children and young people's (CYP) (5-24 years of age) self-reported experiences of asthma self-management strategies (ASMS) with nursing involvement across various settings.

BACKGROUND

Childhood asthma is an increasingly significant health issue, highlighting the importance of acquiring self-management skills to optimise future health outcomes. Registered nurses play a pivotal role in delivering appropriate, personalized self-management support.

METHODS

This integrative review searched four electronic databases: Cumulated Index to Nursing and Allied Health Literature via Elton B. Stephens Company, Medical Literature Analysis and Retrieval System Online (MEDLINE), Object, View and Interactive Design (OVID), and PubMed, that followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis flowchart. Included studies were critically appraised using the Joanna Briggs Institute critical appraisal tools. Braun and Clarks thematic analysis was used to generate themes, and sub-themes.

FINDINGS

Fifteen studies were included for review. Thematic analysis generated three themes being healthy literacy; health and wellbeing; and tools and working together.

CONCLUSIONS

Asthma continues to have negative physical, psychological, and social implications among CYP. CYP are both willing and capable of engaging in ASMS and learning self-management skills, however, continue to have unmet self-management needs.

IMPLICATIONS TO PRACTICE

Strategies must bolster health literacy, improve physical and psychological health, and harness interactive, youth-centric, and informative tools to facilitate communication and decrease the burden of self-management. Applications pose a promising avenue for self-management support. This age group remains under-explored and future research should enable meaningful engagement with CYP to better understand their perspectives and improve strategy success.

Concordance of provider chart notation and guideline-based classification of asthma severity

OBJECTIVE

To evaluate concordance of asthma severity classification via physician chart notation compared with guideline-based criteria in adolescents with diagnosed asthma.

METHODS

Of 284 urban primary care and subspecialty clinic patients aged 13-18 years approached through convenience sampling, 203 surveys were completed (RR = 71.5%). We assessed concordance with sensitivity, specificity, and positive predictive values; overall agreement was evaluated with weighted kappa coefficients and McNemar's test.

RESULTS

When considering prescribed treatment according to NAEPP guidelines as a gold standard, the sensitivity for chart notation was very good for intermittent (95%) and less for non-intermittent severity ratings (51%, 58%, and 67% for moderate, severe, and mild persistent asthma, respectively). Overall agreement between chart notation and guideline-based asthma criteria ranged from fair-to-good for mild- (k = 0.36), moderate- (k = 0.44), and severe-persistent severity (k = 0.66). Although the agreement for intermittent severity was highest (k = 0.88), it did not significantly differ by between the two classifications (p ≥ 0.05).

CONCLUSIONS

Concordance for all non-intermittent asthma severity classifications varied between physician and medication-driven 2007 NAEPP guideline classifications in an ethnically diverse urban adolescent patient sample. Physicians should remain aware of the potential for this discordance and refer to the guidelines to classify and treat adolescents with asthma.

Sore and tired. A qualitative study exploring the symptom experience of youth with bronchiectasis

This qualitative study was conducted to explore the experiences of youth living with bronchiectasis in New Zealand (NZ). Semi-structured interviews were conducted with youth with bronchiectasis. Key themes were identified using an inductive approach through constant comparative analysis and guided by Thorne's interpretive description (ID). Fifteen young people of mixed ethnicity (nine females and six males) aged between 13 and 23 years participated. Three key themes 'sore and tired', 'life interrupted and 'looking after self' were identified. This paper will focus on 'sore and tired' and its three subthemes which describe the participants symptom experience. While there was variability in physical symptom patterns, cough, soreness and fatigue were prominent features impacting physical, emotional and social aspects of day-to-day life. All identified pervasive and profound fatigue as significant. The identification of prodromal symptoms provides opportunity for greater appreciation of the varied and personal symptom experience of young people with bronchiectasis. Early identification of these symptoms and inclusion within management plans for escalating treatment has the potential to improve outcomes, reducing delays in seeking additional medical management and preventing further exacerbation.

Sex Differences in the Relationship Between Asthma and Bullying Victimization Among High School Students in the United States

BACKGROUND

Children with asthma are often marginalized at school, including bullying victimization. The purpose of this study is to estimate the association between asthma and school or electronic bullying victimization among US high school students, and test whether the association varies significantly by sex.

METHODS

Pooled data from five waves of the Youth Risk Behavior Survey (N = 73,074) were used. Additive interactions were estimated in R software as per STROBE guidelines.

RESULTS

Asthma increases the risk of bullying victimization among female and male adolescents. The risk of school bullying was significantly greater among female students with asthma (7.3%) compared to males (4.0%, p = .002). Similarly, the increased risk for electronic bullying victimization associated with asthma was significantly greater among female (7.2%) than among male students (3.4%, p < .001).

CONCLUSIONS

Targeted educational interventions to decrease bullying victimization among adolescents with asthma are needed to mitigate its negative impacts.

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.

Mapping Relevance of Digital Measures to Meaningful Symptoms and Impacts in Early Parkinson's Disease

BACKGROUND

Adoption of new digital measures for clinical trials and practice has been hindered by lack of actionable qualitative data demonstrating relevance of these metrics to people with Parkinson's disease.

OBJECTIVE

This study evaluated of relevance of WATCH-PD digital measures to meaningful symptoms and impacts of early Parkinson's disease from the patient perspective.

METHODS

Participants with early Parkinson's disease (N = 40) completed surveys and 1:1 online-interviews. Interviews combined: 1) symptom mapping to delineate meaningful symptoms/impacts of disease, 2) cognitive interviewing to assess content validity of digital measures, and 3) mapping of digital measures back to personal symptoms to assess relevance from the patient perspective. Content analysis and descriptive techniques were used to analyze data.

RESULTS

Participants perceived mapping as deeply engaging, with 39/40 reporting improved ability to communicate important symptoms and relevance of measures. Most measures (9/10) were rated relevant by both cognitive interviewing (70-92.5%) and mapping (80-100%). Two measures related to actively bothersome symptoms for more than 80% of participants (Tremor, Shape rotation). Tasks were generally deemed relevant if they met three participant context criteria: 1) understanding what the task measured, 2) believing it targeted an important symptom of PD (past, present, or future), and 3) believing the task was a good test of that important symptom. Participants did not require that a task relate to active symptoms or "real" life to be relevant.

CONCLUSION

Digital measures of tremor and hand dexterity were rated most relevant in early PD. Use of mapping enabled precise quantification of qualitative data for more rigorous evaluation of new measures.

Adolescents' practical knowledge of asthma self-management and experiences in the context of acute asthma: a qualitative content analysis

OBJECTIVE

To characterize adolescents' practical knowledge of asthma self-management and experiences during acute asthma episodes, and compare practical knowledge between minority and non-minority groups.

METHODS

We conducted a secondary analysis using a qualitative descriptive design of textual data collected from 126 adolescents that participated in a randomized controlled trial of an asthma self-management program. Directed content analysis was conducted using four constructs of asthma self-management including symptom prevention, symptom monitoring, acute symptom management, and symptom communication.

RESULTS

Most of the adolescents knew how to prevent exercised-induced bronchoconstriction, but had limited understanding about how to assess and monitor the severity of acute symptoms, appropriately use bronchodilators, seek timely medical help, and communicate acute symptoms to caregivers or healthcare providers during a slow-onset and rapid-onset asthma attack. More minority participants monitored asthma using peak expiratory flow than non-minority participants, who often relied on symptom-based monitoring. Minority adolescents more frequently mentioned bronchodilator use to manage asthma attacks, while non-minority adolescents often reported use of complementary and alternative approaches. Minority youth mentioned accessing healthcare services for acute episodes more often than their non-minority counterparts. Minority participants mentioned communicating acute symptoms to their providers, or family members less frequently than non-minority youth.

CONCLUSIONS

Adolescents have insufficient practical knowledge about ways to prevent and manage acute asthma. Periodic assessment of learning needs related to asthma attacks should be considered a routine part of clinical visits for adolescents to provide targeted information support to address their identified needs.

Children's and adolescents' descriptors of asthma symptoms: An integrative review

Background

Accurate assessment of asthma symptoms is central to appropriate treatment and management; however effective communication about symptoms-how it is perceived and reported-remain challenging in pediatric clinical and research settings.

Objective

To synthesize the existing pediatric literature on children's and adolescents' word descriptors of asthma symptoms.

Methods

In this integrative review, we systematically searched Cumulative Index of Nursing and Allied Health Literature and PubMed databases to identify original research studies from 1980 to 2021 on children and adolescents' word descriptors of asthma symptoms.

Results

The search yielded 2,232 articles, of which 21 studies met the eligibility criteria. Scientific literature focused on children and adolescents' descriptions of asthma symptoms are limited. In addition to standard asthma symptom terminology (e.g. cough, wheeze, chest tightness, shortness of breath), pediatric populations used nonstandard word choices to describe the asthma symptom experience. Children and adolescents used a variety of affective (e.g. 'helpless', 'afraid of dying') and sensory words (e.g. 'pressure in chest', 'tightness, lungs feel shut') to describe the phenomena. Literature examining race differences in word descriptors in pediatrics is limited; thus it is unclear if word descriptors vary by race or ethnicity. Evidence of relationships between descriptors and gender and age are also lacking.

Conclusions

Our review elucidates gaps in the literature regarding the full extent of the language common to racially and ethnically diverse samples of children and adolescents. Further research is warranted to help clinicians and researchers query children and adolescents' experience of asthma symptoms.

Are Mid to Late Adolescents with Asthma Ready for Transition of Care? A Qualitative Study

This qualitative descriptive study explores experiences and perspectives of mid-to-late adolescents about growing up with asthma, and the roles of parents and providers as they transition. Purposeful sampling was used to recruit and enroll adolescents aged 16-20 years with asthma. Forty-one adolescents participated in a focus group or individual interview, and content analysis was conducted to analyze the data. The mean age of participants was 17.7 years, the majority (56%) of whom were Black. Themes that emerged included concerns about becoming an adult with asthma and its self-management, parental involvement, and communication with providers. Adolescents felt burdened by asthma, few considered becoming adults with asthma, and their future outlook was pessimistic with concerns related to worsening symptoms, inadequacy in symptom self-management and limitations on career choices due to asthma. Deficiencies in self-management were noted, parents still played major roles in adolescents' asthma care, and transition of care was seldom discussed with the providers. Mid-to-late adolescents with asthma are inadequately prepared for transition of care, and parents and providers insufficiently engage adolescents in the preparation. Parent, provider, and adolescent partnership is critical to achieve adolescent readiness for independence in asthma management and to ensure proper asthma care continuity post transition.

Sustained Effects From a School-Based Intervention Pilot Study for Children With Asthma and Anxiety

Children with chronic conditions (i.e., asthma) are more likely to have anxiety or depressive symptoms. Comorbid asthma and anxiety in children leads to increased morbidity, causing children to miss instructional time and parent/caregiver (CG) work absences. Asthma educational programs and mental health interventions have been developed, though no scalable programs integrate asthma education and mental health behavioral interventions for school-aged children. This study evaluated the sustained preliminary effects of an integrated asthma education and cognitive behavioral skills-building program, Creating Opportunities for Personal Empowerment for Asthma. Thirty-two children ages 8-12 years with asthma and symptoms of anxiety received the intervention. At 6-weeks postintervention, anxiety and CG-reported behavioral symptoms were significantly reduced, there were fewer missed doses of asthma controller medications, and asthma-related self-efficacy, personal beliefs, and the children's understanding of asthma significantly increased. Most children (n = 29, 91%) reported continued use of coping skills.

Development of a motivation-based tool to facilitate individualized self-management interventions for adolescents with asthma

OBJECTIVE

To develop a questionnaire for segmenting adolescents with asthma into archetypes based on their motivations for individualized self-management interventions.

METHODS

A prospective observational study using segmentation methodology. First, adolescents created photo diaries followed by in-person semi-structured interviews to develop a pool of candidate items for identifying and describing archetypes. Second, quantitative methods were used to test the pool of items to determine which ones best identified each archetype.

RESULTS

Six archetypes based on motivations were identified and described: goal oriented visionaries; mentors and helpers; influencers; discouraged adolescents; dependent adolescents; and shame avoiders. A questionnaire with 63 candidate items was administered to 201 adolescents. Confirmatory factor analysis resulted in a 17-item questionnaire that identified the archetypes.

CONCLUSION

This study is the first step towards applying a segmentation methodology to facilitate the application of interventions during a clinic visit to increase adherence. It has shown that a relatively short questionnaire can be used to identify archetypes based on motivations.

PRACTICE IMPLICATIONS

The 17-item questionnaire could provide a framework and direction for healthcare professionals to customize existing adherence interventions, such as motivational interviewing, to different segments of adolescents. It would be especially helpful in primary care settings where time is limited.

Understanding the journeys of patients with an asthma exacerbation requiring urgent therapy at a primary care clinic

BACKGROUND

Asthma is a significant health issue in primary care. We examined the journeys of patients with asthma exacerbations requiring urgent therapy at a primary care clinic in Singapore.

METHODS

Face-to-face semi-structured interviews were conducted with patients who received urgent therapy for asthma exacerbation at a primary care clinic. Data collected was used to construct themes.

RESULTS

Fifteen multi-ethnic adult patients were recruited. Participants cited treatment cost, underuse of preventer medication, difficulties attending routine asthma care due to work, and stigma as barriers to asthma control. Reasons for delay in seeking urgent care for asthma were: inability to access medical care out of hours, competing priorities, perception that an exacerbation was 'not serious enough', difficulty recognizing symptoms of asthma exacerbation, and being tired or despondent. Participants were triggered to seek care due to failure of reliever inhalers, duration of symptoms, sleep disturbance, inability to work, or advice from others. During an exacerbation, participants often initiated other self-management measures besides using reliever medication. This included over-the-counter medications and non-pharmacological interventions (e.g. drinking water). Of the 15 patients interviewed, only one stepped up preventer inhaler adequately, according to their Asthma Action Plan (AAP).

CONCLUSIONS

In caring for patients with asthma, primary care providers should address patients' asthma self-management skills, such as recognizing symptoms of asthma exacerbations and regular preventer use, and provide clear instructions on how to respond to asthma symptoms (AAP). Minimizing direct (medication and consultation fees) and indirect costs (loss of earnings and adverse impact on employment prospects) are also important considerations.

Physician's experience on managing asthma in adolescents: results of the International AMADO (Asthma Management in ADOlescents) survey

Background

Worldwide prevalence of asthma seems to be increasing in adolescents, but limited data is available regarding the management of asthma in this age group.

Objective

Therefore, we conducted an international survey focused on physicians who manage asthma in order to understand how Asthma Management in ADOlescents (AMADO) is currently performed.

Methods

The AMADO survey is a web-based global survey of physician's attitudes towards the management of asthma in adolescents, circulated for 17 weeks. The survey had an anonymous and voluntary standard. The questionnaire consisted in 27 questions covering the training background of respondents, difficulties in diagnosis, and in management of asthma in adolescents.

Results

Two hundred forty-four responses were received from 46 countries, from all continents. Most (65%) of participants indicated allergy as being their main specialty. The majority of participants (62%) had more than 5 years of clinical practice, but 62% have no formal training in management of adolescents with asthma. Most of participants (96%) indicated having at least one case of asthma in adolescents per month. 60% of respondents mentioned that the asthmatic adolescents only had the consultation due to the family imposition. All respondents mentioned having difficulties in the management of asthma in adolescents due to patient poor adherence. Overall, 44% of participants have no specific health care resources for adolescents in their departments. Main suggestions from the participants were: optimization of time and personalized communication to these cohort, and standardization of multidisciplinary actions to improve adherence to asthma control treatment.

Conclusion

Management of asthma in adolescents is still a challenge in clinical practice. The results from this survey helped us to identify the key issues to improve clinical outcomes in the future. This survey is the first step of the international AMADO initiative, which intends to optimize diagnosis and control of asthma and prevent avoidable deaths.

Parental beliefs and willingness to pay for reduction in their child's asthma symptoms: A joint estimation approach

Many aspects of asthma-in particular the relationship between beliefs, averting behaviors, and symptoms-are not directly observable from market data. An approach that combines observable market data with nonmarket valuation to gather data on unobservable aspects of the illness can improve efforts to quantify the burden of asthma if it accounts for the endogeneity in the system. Such approaches are used in the valuation of recreation but have not been widely used to value the burden of a chronic illness. We estimate parents' willingness to pay (WTP) to reduce their child's asthma symptoms using a three-equation model that combines revealed preference, contingent valuation, and burden of asthma, increasing the efficiency of estimation and correcting for endogeneity. WTP for a device that reduces a child's asthma symptoms by 50% is $125/month (s.d. $20). Parents' valuations are driven by beliefs about asthma and by their degree of worry about asthma between episodes. There is a nonlinear relationship between the number of days with symptoms and WTP per symptom day. The experience of living with asthma affects families' responses to a contingent valuation scenario, because it influences willingness to spend money to manage the illness and their subjective perceptions and beliefs about the illness itself.

A mixed-methods analysis of younger adults' perceptions of asthma, self-management, and preventive care: "This isn't helping me none"

BACKGROUND

Young adults (ages 18-44) have increased emergency department use for asthma and poor adherence to medications. The objective of this mixed-methods study was to understand experiences with and approaches to managing asthma, of which little is known in this age group.

METHODS

Surveys (Asthma Control Questionnaire, Asthma Quality of Life Questionnaire) and 1:1 semi-structured interviews were used to explore experiences with asthma, symptoms, self-management behaviours, and relationship to asthma control and quality of life. Qualitative data were analysed using content analysis techniques. Descriptive statistics and bivariate correlations were used to examine distributive characteristics and associations between variables.

RESULTS

Forty urban adults participated (mean age 32.7 ± 6.2, 1σ). Coughing was reported nearly 46% more often than wheezing, with 42.5% (17/40) coughing until the point of vomiting most days. Most participants delayed using medication for symptoms due to misperceptions about inhalers. Higher symptom frequency and worse asthma control were associated with greater use of non-pharmacologic symptom management strategies (r = 0.645, P < .001; r = 0.360, P = .022, respectively). Five themes were identified regarding young adults experiences with asthma: (1) having asthma means being limited and missing out on life; (2) health care for asthma is burdensome, and other things are more important; (3) there is not enough personal benefit in medical interactions to make preventive care worthwhile; (4) there are insufficient support and education about asthma for adults; and (5) people normalize chronic symptoms over time and find ways of coping that fit with their lifestyle.

CONCLUSIONS AND CLINICAL RELEVANCE

Young adults may tolerate symptoms without using quick-relief medication or seeking preventive care. Increasing engagement with preventive services will require decreasing perceived burdens and increasing the personal benefits of care. Evaluating for non-pharmacologic approaches to managing symptoms and asthma-related coughing may identify uncontrolled asthma. Enhanced training for clinicians in patient-centric asthma care may be needed.

EAACI Guidelines on the effective transition of adolescents and young adults with allergy and asthma

Adolescent and young adult (AYA) patients need additional support, while they experience the challenges associated with their age. They need specific training to learn the knowledge and skills required to confidently self-manage their allergies and/or asthma. Transitional care is a complex process, which should address the psychological, medical, educational and vocational needs of AYA in the developmentally appropriate way. The European Academy of Allergy and Clinical Immunology has developed a clinical practice guideline to provide evidence-based recommendations for healthcare professionals to support the transitional care of AYA with allergy and/or asthma. This guideline was developed by a multidisciplinary working panel of experts and patient representatives based on two recent systematic reviews. It sets out a series of general recommendations on operating a clinical service for AYA, which include the following: (a) starting transition early (11-13 years), (b) using a structured, multidisciplinary approach, (c) ensuring AYA fully understand their condition and have resources they can access, (d) active monitoring of adherence and (e) discussing any implications for further education and work. Specific allergy and asthma transition recommendations include (a) simplifying medication regimes and using reminders; (b) focusing on areas where AYA are not confident and involving peers in training AYA patients; (c) identifying and managing psychological and socio-economic issues impacting disease control and quality of life; (d) enrolling the family in assisting AYA to undertake self-management; and (e) encouraging AYA to let their friends know about their allergies and asthma. These recommendations may need to be adapted to fit into national healthcare systems.

Associations between overweight and obesity and asthma outcomes in urban adolescents

Objective: To examine the prevalence of overweight and obesity in urban adolescents with asthma and to investigate the relationships between anthropometric measures and asthma outcomes including quality of life, asthma control and lung function.Methods: Adolescents with an asthma diagnosis, 12-20 years-old, were recruited from three urban communities in the United States. Spirometry and anthropometric data including height, weight and waist circumferences were collected along with questionnaire data measuring quality of life, asthma control, and medication adherence. Body mass index (BMI) and waist-height ratio (WHtR) were computed.Results: The sample (N = 294) included 48% female and 80% African American. About 50% of the sample were either overweight or obese, and 41% had central obesity. No significant gender interactions with either BMI or WHtR on asthma outcomes were found. Neither BMI nor WHtR predicted quality of life, asthma control or medication adherence, while females had poorer quality of life and asthma control regardless of weight status (p < 0.001). Higher BMI or WHtR predicted higher spirometry values. Regardless of weight status, females had greater percent predicted spirometry values, while raw values (L) were significantly greater in males.Conclusions: High BMI is a common comorbidity among poor, primarily African American, urban adolescents with asthma. The negative impact of being overweight or obese on quality of life or asthma control is yet to be manifested in adolescents. The findings underscore adolescence as an ideal period to safely intervene to reduce excessive body weight, which can prevent the potentially harmful effects of obesity on future asthma outcomes.

Asthma self-management in children: a best practice implementation project

INTRODUCTION

Asthma is one of the most common diseases in children. A self-management program can effectively improve the outcomes for children with asthma and reduce the burden on healthcare services.

OBJECTIVES

The aim of this project was to integrate the best evidence on asthma self-management with practice in a children's respiratory clinic and to improve compliance with best practice.

METHODS

Seven audit criteria were developed for the pre- and post-audit based on the best available evidence. The Joanna Briggs Institute (JBI) Practical Application of Clinical Evidence System and Getting Research into Practice audit and feedback tools were used in this project.

RESULTS

The baseline audit showed a gap between clinical practice and the best evidence. The only criterion that achieved high compliance was provision of inhaler guidance (100%). After implementation, there were substantial improvements in compliance for many criteria. Training of clinicians increased from 13% at baseline to 67% at follow-up. Education of parents improved, with specific education about asthma triggers increasing from 55% to 100%, education about warning signs from 30% to 85% and education about effective asthma treatment options from 40% to 85%. Use of written asthma action plans increased from 0% to 25%.

CONCLUSION

Strategies developed in this project were effective at providing necessary information for parents and improved the compliance with evidence. Further implementation strategies and audits are still needed to improve the use of asthma action plans and ensure they are reviewed periodically.

How young children learn independent asthma self-management: a qualitative study in Malaysia

OBJECTIVE

We aimed to explore the views of Malaysian children with asthma and their parents to enhance understanding of early influences on development of self-management skills.

DESIGN

This is a qualitative study conducted among children with asthma and their parents. We used purposive sampling and conducted focus groups and interviews using a semi-structured topic guide in the participants' preferred language. All interviews were audio-recorded, transcribed verbatim, entered into NVivo and analysed using a grounded theory approach.

SETTINGS

We identified children aged 7-12 years with parent-reported, physician-diagnosed asthma from seven suburban primary schools in Malaysia. Focus groups and interviews were conducted either at schools or a health centre.

RESULTS

Ninety-nine participants (46 caregivers, 53 children) contributed to 24 focus groups and 6 individual interviews. Children mirrored their parents' management of asthma but, in parallel, learnt and gained confidence to independently self-manage asthma from their own experiences and self-experimentation. Increasing independence was more apparent in children aged 10 years and above. Cultural norms and beliefs influenced children's independence to self-manage asthma either directly or indirectly through their social network. External influences, for example, support from school and healthcare, also played a role in the transition.

CONCLUSION

Children learnt the skills to self-manage asthma as early as 7 years old with growing independence from the age of 10 years. Healthcare professionals should use child-centred approach and involve schools to facilitate asthma self-management and support a smooth transition to independent self-management.

Understanding the challenges faced by adolescents and young adults with allergic conditions: A systematic review

BACKGROUND

Adolescence represents a vulnerable time for individuals with asthma and allergic conditions. They suffer an unexpected degree of morbidity. This systematic review aimed to understand the challenges faced by adolescents and young adults with these conditions.

METHODS

A systematic literature search was undertaken across eight databases. References were checked by two reviewers for inclusion. Study data were extracted, and their quality was assessed in duplicate. A narrative meta-synthesis was undertaken.

RESULTS

A total of 108 papers describing 106 studies were retrieved, most focused on asthma. Five themes were identified across studies: (a) Health-related quality of life-impairment was associated with poor disease control, psychosocial issues, adolescent-onset allergic disease and female sex; (b) Psychological factors-asthma and food allergy were associated with anxiety and depression, atopic dermatitis was associated with suicidal ideation, and that parental emotional support may be protective; (c) Adherence-suboptimal adherence was associated with older age, barriers to medication usage, poor symptom perception and failure to take responsibility, and positive factors were routines, simpler treatment regimes, better knowledge and perceptions about medications; (d) Self-management-facilitated by education, knowledge and a positive attitude; and (e) Supportive relationships-families could modify barriers to adherence and foster positive views about self-management, adolescents suggested that their peers should be more involved in supporting them, and adolescents also wished to have support from nonjudgemental healthcare professionals.

CONCLUSIONS

We have some understanding of the challenges faced by adolescents with asthma, less so for other allergic conditions. This knowledge will be used to support guidelines for managing adolescents.

Parent Perspectives on Family-Based Psychosocial Interventions for Congenital Heart Disease

OBJECTIVES

To identify parents' preferences for goals and structure of intervention programs to support the psychosocial needs of families impacted by congenital heart disease (CHD).

STUDY DESIGN

Information about parent priorities for psychosocial programs was obtained in this mixed-methods study conducted at a pediatric hospital in the Mid-Atlantic region of the US. Participants were parents (N = 34; 20 mothers, 14 fathers) of children with CHD between the ages of 1 and 3 years who had cardiac surgery at less than 6 months of age. Qualitative data were excerpts from semistructured interviews. Quantitative data were participant choices regarding their ideal psychosocial program resulting from a card sort.

RESULTS

Parents reported that psychosocial interventions should support partnership in their child's care, promote self-care, facilitate communication with providers, prepare parents for challenges after hospitalization, provide education about child neurodevelopment, and help parents engage social support. Parents reported needing formalized support across care, brief intervention models, in-person individualized or small group support, and involvement of multidisciplinary providers and peer mentors in the delivery of interventions.

CONCLUSIONS

Parents of children with CHD need psychosocial interventions that empower them to act as primary caregivers and effective advocates for their child. Individualized, formalized, and multidisciplinary approaches to psychosocial care are necessary to best accommodate the dynamic stressors related to parenting a child with CHD and may mitigate the impact of parent mental health problems on child outcomes.

Validation of an app-based portable spirometer in adolescents with asthma

OBJECTIVES

Objective measurements of asthma impairment could aid teens in recognition of changes in asthma status over time. Ready access to a conventional spirometer is not realistic outside of the clinical setting. In this proof-of-concept study, we compared the performance of the VitalFlo mobile spirometer to the nSpire KoKo® sx1000 spirometer for accuracy in measuring Forced Expiratory Volume in one second (FEV₁) and Forced Vital Capacity (FVC) in adolescents with asthma.

METHODS

Two hundred forty pulmonary function measurements were collected from 48 adolescents with persistent asthma from the University of North Carolina's pediatric allergy and pulmonology subspecialty clinics. Participants performed spirometry with the nSpireKoKo® sx1000 spirometer and the VitalFlo spirometer during their clinic visits. 119 simulated FVC maneuvers were conducted on both devices to standardize measurements. Pearson correlations, Bland-Altman procedure, and two-sample comparison tests were performed to assess the relationship between the two spirometers.

RESULTS

VitalFlo measurements were significantly highly correlated with nSpireKoKo® spirometer values for FEV_1, (r²=0.721, [95% CI, 0.749 ± 0.120], P < 0.001) and moderately for FVC (r²= 0.617, [95% CI, 0.640 ± 0.130], P < 0.001) measurements. There were no statistically significant differences of the mean FEV₁ (M = 0.00764, SD = 0.364, t(59)=0.16, P = 0.87) and FVC measurements (M = 0.00261, SD = 0.565, t(59)=0.036, P = 0.97.) between the VitalFlo and nSpireKoKo® systems. Both devices demonstrated significantly high correlation when comparing the automated FVC (r² = 0.997, [95% CI, 1.00 ± 0.00974], P < 0.001) measurements. Bland-Altman plots did not demonstrate significant bias between devices for both FEV₁ (0.00764 L) and FVC (0.00261 L) measurements.

CONCLUSIONS

Lung function measurements from the VitalFlo mobile spirometer were comparable to a commercially-available spirometer commonly used in clinical settings. This validated app-based spirometer for home use has the potential to improve asthma self-management.

Fostering Effective Asthma Self-Management Transfer in High-Risk Children: Gaps and Opportunities for Family Engagement

INTRODUCTION

The process of self-management knowledge, behavior, and skill development in children with asthma from families with low income is understudied.

METHOD

Fifteen mothers of children with uncontrolled asthma participated in semistructured interviews exploring the transfer of asthma self-management responsibilities from parent to child. Team members performed thematic analysis of written transcripts.

RESULTS

All participants were all the biological mothers and were impoverished, with most (73%) reporting an annual family income of less than $30,000. Their children ranged from 5 to 15 years old, were African American (100%), and had uncontrolled asthma based on national guidelines. Themes showed that child asthma self-management is difficult to achieve, that the transfer of asthma responsibility from mother to child is variable, and that mothers overestimate their child's developmental capacities for independent asthma self-management and have poor understanding of what well-controlled asthma means.

DISCUSSION

Ongoing assessment and tailored guidance from health care providers are critical to support the pivotal role of mothers in their child's self-management development process.

Lung function and asthma control in school-age children managed in UK primary care: a cohort study

BACKGROUND

Spirometry and fraction of exhaled nitric oxide (FeNO) are commonly used in specialist centres to monitor children with asthma. The National Institute for Health and Care Excellence recommends spirometry for asthma monitoring from 5 years in all healthcare settings. There is little spirometry and FeNO data in children managed for asthma in UK primary care to support their use.

OBJECTIVES

To study the prevalence of abnormal spirometry and FeNO in children with asthma managed in primary care and to explore their relationship with asthma control and unplanned healthcare attendances (UHA).

METHODS

Prospective observational cohort study in children aged 5-16 years with suspected or doctor-diagnosed asthma attending an asthma review in UK general practice. Spirometry, FeNO, asthma control test (ACT) scores and number of UHAs were studied.

RESULTS

Of 612 children from 10 general practices, 23.5% had abnormal spirometry, 36.0% had raised FeNO ≥35 parts per billion and 41.8% reported poor control. Fifty-four per cent of children reporting good asthma control had abnormal spirometry and/or raised FeNO. At follow-up, the mean number of UHAs fell from 0.31/child in the 6 months preceding review to 0.20/child over the 6 months following review (p=0.0004). Median ACT scores improved from 20 to 22 (p=0.032), and children's ACT from 21 to 23 (p<0.0001).

CONCLUSIONS

Abnormal lung function and FeNO are common in children attending for asthma review in primary care and relate poorly to symptom scores. A symptoms-based approach to asthma monitoring without objective testing is likely to miss children at high risk of future severe asthma attacks.

A Mixed-methods Study Examining Inhaler Carry and Use among Children at School

Objective: Asthma self-management depends partly on access to inhalers; for children, this includes independent inhaler carry and use at school ("self-carry"). Although laws and policies support self-carry, little is known about practices within schools. This study aimed to identify factors associated with inhaler self-carry among children and examine barriers and facilitators to self-carry.Methods: This mixed-methods observational study included child-parent dyads and nurses from four Chicago schools. Children and parents answered questions about asthma care and morbidity, confidence in self-carry skills, and facilitators and barriers to self-carry. Nurses reported asthma documentation on file and their confidence in children's self-carry skills. Analysis utilized logistic regression. Thematic analysis was performed for open-ended questions.Results: Of 65 children enrolled (mean = 10.66 years), 45 (69.2%) reported having quick-relief medication at school, primarily inhalers, and 35 (53.8%) reported self-carry. Inhaler self-carry was associated with controller medication use and parent confidence in child's self-carry skills. Children and parents identified several facilitators to self-carry: child's asthma knowledge, inhaler characteristics, and need for easy inhaler access. Barriers included child's limited understanding of asthma and inhalers, perception that inhaler is not needed, and limited inhaler access. Children also emphasized social relationships as facilitators and barriers, while parents described children's responsibility as a facilitator and inconsistent policy implementation as a barrier.Conclusions: Efforts to improve inhaler self-carry at school should focus on educating children about asthma and inhaler use, creating supportive environments for self-carry among peers and teachers, and fostering consistent implementation and communication about asthma policy among schools and families.

An integrated operational definition and conceptual model of asthma self-management in teens

OBJECTIVES

A previous definition of adolescent asthma self-management was derived from interviews with clinicians/researchers and published literature; however, it did not incorporate perspectives of teens or parents. Therefore, we conducted in-depth interviews with teens and parents and synthesized present findings with the prior analysis to develop a more encompassing definition and model.

METHODS

Focal concepts were qualitatively extracted from 14-day self-management voice-diaries (n = 14) and 1-hour interviews (n = 42) with teens and parents (28 individuals) along with concepts found in the previous clinical/research oriented analysis. Conceptual structure and relationships were identified and key findings synthesized to develop a revised definition and model of adolescent asthma self-management.

RESULTS

There were two primary self-management constructs: processes of self-management and tasks of self-management. Self-management was defined as the iterative process of assessing, deciding, and responding to specific situations in order to achieve personally important outcomes. Clinically relevant asthma self-management tasks included monitoring asthma, managing active issues through pharmacologic and non-pharmacologic strategies, preventing future issues, and communicating with others as needed. Self-management processes were reciprocally influenced by intrapersonal factors (both cognitive and physical), interpersonal factors (family, social and physical environments), and personally relevant asthma and non-asthma outcomes.

CONCLUSION

This is the first definition of asthma self-management incorporating teen, parent, clinician, and researcher perspectives, which suggests that self-management processes and behaviors are influenced by individually variable personal and interpersonal factors, and are driven by personally important outcomes. Clinicians and researchers should investigate teens' symptom perceptions, medication beliefs, current approaches to symptom management, relevant outcomes, and personal priorities.

Mixed-methods content and sentiment analysis of adolescents' voice diaries describing daily experiences with asthma and self-management decision-making

BACKGROUND

Accurate symptom assessment remains challenging in teen populations. Little is known of usual symptom/response patterns, and self-reported paper diaries have traditionally low compliance rates. Therefore, we used concurrent digital voice diaries to capture daily asthma experiences.

OBJECTIVE

(a) To qualitatively explore usual symptom patterns and self-management responses and (b) to quantitatively explore relationships between symptom severity and sentiment scores (a marker of emotional response to events).

METHODS

Fourteen minority and nonminority teenagers (age 13-17) with controlled (50%) and uncontrolled asthma used digital recorders to report about their asthma once daily over 14 days. Dairy entries were coded for symptom frequency, severity, type, and self-management responses, while sentiment analysis was used to evaluate the emotional valence of diary entries and to explore whether increased symptom levels correlated with greater negative sentiment.

RESULTS

Symptom frequency and severity recorded in voice diaries were much higher than teens indicated at baseline and were discordant with clinical assessments of asthma control. Of 175 entries, teens had symptoms 69.1% of days (121/175) and severe symptoms on one-third of these. Atypical symptoms (coughing, throat clearing) were reported twice as often as traditional symptoms (wheezing, chest tightness) and often not recognized as asthma, but rather attributed to being "sick" (25.6% of symptom days). Teens frequently minimized symptoms, used rescue and controller medication inconsistently, and resorted to alternative strategies to manage symptoms. Sentiment was not significantly correlated with assessed control (β = 0.14, P = 0.28), but for teens reporting severe symptoms, sentiment scores decreased by 0.31 relative to teens without symptoms (P = 0.006).

CONCLUSIONS AND CLINICAL RELEVANCE

Teens may minimize symptoms and have greater symptom frequency and severity than is recognized by themselves or providers. Screening for specific symptoms including coughing, throat clearing, and respiratory illness may be needed to identify those experiencing burden from asthma.

Comparing Asthma Control Questionnaire (ACQ) and National Asthma Education and Prevention Program (NAEPP) asthma control criteria

BACKGROUND

Adequate assessment of control is critical to asthma management. The Asthma Control Questionnaire (ACQ) and the National Asthma Education and Prevention Program (NAEPP) criteria are commonly used measures of asthma control.

OBJECTIVE

To examine the associations between the ACQ and NAEPP criteria and compare the validity in association with lung function, asthma exacerbation, and quality of life.

METHODS

The ACQ and the NAEPP criteria were administered to 373 adolescents with asthma aged 12 to 20 years. The 2 measures correlated with forced expiratory volume in 1 second (FEV₁), asthma exacerbation (oral corticosteroid use, hospitalization, and emergency department [ED] use) in the past 12 months, and quality of life.

RESULTS

Agreement between the ACQ and NAEPP criteria was moderate (κ = 0.40-0.61). Neither of the 2 measures was a reliable predictor of FEV₁ less than 80% because of the high rate of false-positive results for the ACQ (68%) and low sensitivity for the NAEPP (49%). The NAEPP identified more cases of uncontrolled asthma (84.6%) than the ACQ (64.6%). The ACQ was a significant predictor of recent oral corticosteroid use, hospitalization, and ED visits (area under the curve = 0.66, 0.66, and 0.64, respectively; P < .001), as was NAEPP (area under the curve = 0.63, 0.66, and 0.61, respectively; P < .001). Both measures were significantly associated with quality of life, and the associations were particularly strong for the ACQ (r = -0.87 for symptom subscale, r = -0.76 for activity subscale, and r = -0.78 for emotional function subscale).

CONCLUSION

Neither the ACQ nor the NAEPP appears to reliably predict lung function, whereas both measures reasonably associate with acute asthma exacerbation. The ACQ may be the superior measure in gauging the psychosocial effect of asthma control given its particularly strong associations with quality of life.

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.

Barriers and facilitators to self-management of asthma in adolescents: An interview study to inform development of a novel intervention

BACKGROUND AND OBJECTIVE

Despite literature that spans twenty years describing the barriers to asthma self-management in adolescents, successful, clinically based interventions to address this important issue are lacking. Given the limitations of some of the previous studies, we conducted a study that aimed to gain a broader insight into barriers and facilitators to self-management of asthma by adolescents, not just adherence to treatment, and triangulated their views with those of their parents and healthcare professionals.

METHODS

Focus groups and interviews were conducted separately for 28 adolescents with asthma aged 12-18 years, 14 healthcare professionals and 12 parents. Focus groups and interviews were audio-recorded, and transcripts from each participant group were analysed separately using inductive thematic analysis. We triangulated the three perspectives by comparing themes that had emerged from each analysis.

RESULTS

Adolescents', parents' and healthcare professionals' views were summarized into ten related themes that included forgetting and routines, knowledge, embarrassment and confidence, communication with healthcare professionals, triggers, support at school, apathy and taking responsibility. We found that adolescents, parents and healthcare professionals raised similar barriers and facilitators to self-management and our results provide further validation for previous studies.

CONCLUSION AND CLINICAL RELEVANCE

Our study highlights that healthcare professionals may need to consider a range of psychological and contextual issues influencing adolescents' ability to effectively self-manage their asthma, in particular, how they implement treatment routines and the understanding that adolescents have of their condition and treatments. Crucially, healthcare professionals need to consider how this information is communicated and ensure they facilitate open, inclusive, two-way consultations. From this more comprehensive understanding, we have developed interventional strategies that healthcare professionals can utilize to empower adolescents to improve their asthma self-management.

Changes in asthma self-management knowledge in inner city adolescents following developmentally sensitive self-management training

OBJECTIVE

To evaluate efficacy of a developmentally sensitive curriculum for improving asthma self-management knowledge, attitude, and self-efficacy in adolescents.

METHODS

Fourty-two inner-city adolescents (ages 16-20) participated in a 12hour asthma self-management training program. Self-management knowledge, attitude toward asthma, and asthma-related self-efficacy were measured using short-answer tests before and after training. T-Tests were used to evaluate impact and effect sizes were calculated.

RESULTS

Mean pretest knowledge was 21.37/46 points; mean posttest was 36.33/46 points. Change from pre- to posttest was highly significant (t=10.34; p<0.0001), with a large effect size (d=1.68). Females improved more than males (18.66±8.58 vs. 12.29±8.13, p=0.039). Greatest effects were seen in awareness of long-term consequences of uncontrolled asthma (d=2.04), ability to recognize symptoms of life-threatening asthma (d=1.61), correctly monitor symptoms (d=1.49), and tell if asthma was uncontrolled (d=1.39). Asthma self-efficacy also improved significantly (p=0.017), particularly confidence in ability to correctly manage asthma, however improvements in attitude did not achieve statistical significance.

CONCLUSION

Developmentally appropriate training is effective in increasing critical self-management knowledge and self-efficacy in inner city adolescents, particularly females.

PRACTICE IMPLICATIONS

Providers should screen carefully for symptoms and educate using developmentally appropriate training materials on ways to correctly monitor and manage symptom.

Barriers and facilitators of effective self-management in asthma: systematic review and thematic synthesis of patient and healthcare professional views

Self-management is an established, effective approach to controlling asthma, recommended in guidelines. However, promotion, uptake and use among patients and health-care professionals remain low. Many barriers and facilitators to effective self-management have been reported, and views and beliefs of patients and health care professionals have been explored in qualitative studies. We conducted a systematic review and thematic synthesis of qualitative research into self-management in patients, carers and health care professionals regarding self-management of asthma, to identify perceived barriers and facilitators associated with reduced effectiveness of asthma self-management interventions. Electronic databases and guidelines were searched systematically for qualitative literature that explored factors relevant to facilitators and barriers to uptake, adherence, or outcomes of self-management in patients with asthma. Thematic synthesis of the 56 included studies identified 11 themes: (1) partnership between patient and health care professional; (2) issues around medication; (3) education about asthma and its management; (4) health beliefs; (5) self-management interventions; (6) co-morbidities (7) mood disorders and anxiety; (8) social support; (9) non-pharmacological methods; (10) access to healthcare; (11) professional factors. From this, perceived barriers and facilitators were identified at the level of individuals with asthma (and carers), and health-care professionals. Future work addressing the concerns and beliefs of adults, adolescents and children (and carers) with asthma, effective communication and partnership, tailored support and education (including for ethnic minorities and at risk groups), and telehealthcare may improve how self-management is recommended by professionals and used by patients. Ultimately, this may achieve better outcomes for people with asthma.

Visual analogue scale (VAS) as a monitoring tool for daily changes in asthma symptoms in adolescents: a prospective study

Background

Success in asthma management hinges on patients’ competency to detect and respond to ever-changing symptom severity. Thus, it is crucial to have reliable, simple, and sustainable methods of symptom monitoring that can be readily incorporated into daily life. Although visual analogue scale (VAS) has been considered as a simple symptom assessment method, its utility as a daily symptom monitoring tool in adolescents is unknown. This study was to determine the concurrent validity of VAS in capturing diurnal changes in symptoms and to examine the relationships between VAS and asthma control and pulmonary function.

Methods

Forty-two adolescents (12–17 years old) with asthma completed daily assessment of symptoms twice per day, morning and bedtime, for a week using VAS and 6-item symptom diary concurrently. Asthma control was measured at enrollment and 6 month later, and spirometry was conducted at enrollment. Pearson correlations, multilevel modeling and regression were conducted to assess the relationships between VAS and symptom diary, asthma control and FEV1.

Results

Morning and evening VAS was positively associated with symptom diary items of each corresponding time frame of the day (r = 0.41–0.58, p < 0.0001). Morning VAS was significantly predicted by morning diary data reflecting nocturnal wakening (β = 2.13, p = 0.033) and morning symptoms (β = 4.09, p = 0.002), accounting for 57% of the total variance of morning VAS. Similarly, changes in four evening diary items, particularly shortness of breath (β = 2.60, p = 0.028), significantly predicted changes in evening VAS, accounting for 55% of the total variance. Average VAS scores correlated with asthma control (r = 0.65, p < 0.001) and FEV1 (r = −0.38, p = 0.029), and were predictive of asthma control 6 months later (β = 0.085, p = 0.006).

Conclusions

VAS is a valid tool capturing diurnal changes in symptoms reflected in a multi-item symptom diary. Moreover, VAS is a valid measure predicting concurrent and future asthma control. The findings suggest VAS can be a simple alternative to daily dairies for daily symptom monitoring, which can provide invaluable information about current and future asthma control without substantially increasing self-monitoring burdens for adolescent patients.

A case of base rate bias, or are adolescents at a higher risk of developing complications after catheterizable urinary channel surgery?

OBJECTIVE

Adolescents are considered to be at high risk of developing complications after lower genitourinary tract reconstruction. This perception may be due to base rate bias, where clinicians favor specific information (adolescents with complications), while ignoring more general information (number of total adolescents being followed). The goal of this study was to assess whether age was a true risk factor for subfascial and stomal revisions after continent catheterizable urinary (CCU) channel procedures.

MATERIALS AND METHODS

Consecutive patients aged <21 years and who underwent appendicovesicostomy and Monti surgery at the present institution were retrospectively reviewed; demographic and surgical data were collected. Time to subfascial or stomal revision was stratified by age at initial surgery (child: <8, preteen: 8-12, adolescent: 13-17, adult: ≥18 years old) and analyzed with Cox proportional-hazards regression. Secondary analyses included: different age categories at initial surgery (<8, 8-11, 12-15, 16-19, ≥20 years), analyzing age as a continuous and a time-varying covariate.

RESULTS

Of the 510 patients with CCU channels (median age at surgery: 7.9 years), 63 (12.4%) had subfascial and 53 (10.4%) had stomal revision (median follow-up: 6.8 years). Median age at subfascial and stomal revision was 11.3 and 10.3 years, respectively. Preteens contributed 33.0% and adolescents contributed 29.3% of the total follow-up time (3263.9 person-years). Over 80% of revisions occurred within 5 years of surgery, regardless of age at initial surgery (P ≥ 0.57) (Summary table). On multivariate analysis, age at initial surgery was not associated with undergoing subfascial (P ≥ 0.62) or stomal revisions (P ≥ 0.69). Montis were 2.1 times more likely than appendicovesicostomies to undergo a subfascial revision (P = 0.03). No other variables were associated with the risk of subfascial or stomal revision (P ≥ 0.11). Secondary analyses provided similar results.

DISCUSSION

Since the median age at surgery was 8 years old and most complications occurred within the first 5 years of follow-up, it is not surprising that most revisions occurred in 8-13 year olds. Pediatric urologists appear to base their impression of adolescents being "high risk" on specific information (adolescents having complications), while subconsciously ignoring more general information (adolescents represent a large proportion of patients in follow-up). This study had several limitations: channel complications treated non-surgically (e.g. prolonged catheterization) were not included. The findings may not be generalizable to other genitourinary reconstructive procedures or clinical settings.

CONCLUSIONS

While complications were twice as high in Monti channels than appendicovesicostomies, no single age group was at increased risk. The impression that adolescents are a high-risk group appears to represent a base rate bias.
