Subjective symptom perceptual accuracy in asthmatic children and their parents in India

Medical Neglect as a Contributor to Poorly Controlled Asthma in Childhood

Child maltreatment, including medical neglect, is a frequent contributor to the development of asthma as well as a barrier to its proper management. This article aims to review the role of medical neglect as a contributor to poor asthma control. Medical neglect can present as failure of the caretaker to recognize severe asthma symptoms in a child, non-adherence to medical management, failure to prevent chronic exposure to allergens or tobacco smoke, poor child nutrition leading to obesity, and allowing a young child to manage his/her illness without supervision. This article will explore the different factors leading to medical neglect (as illustrated by two cases) and suggest possible interventions aiming to prevent emergency department visits, hospitalizations, and asthma-related deaths.

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.

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.

Evaluating the Validity of an Automated Device for Asthma Monitoring for Adolescents: Correlational Design

BACKGROUND

Symptom monitoring is a cornerstone of asthma self-management. Conventional methods of symptom monitoring have fallen short in producing objective data and eliciting patients' consistent adherence, particularly in teen patients. We have recently developed an Automated Device for Asthma Monitoring (ADAM) using a consumer mobile device as a platform to facilitate continuous and objective symptom monitoring in adolescents in vivo.

OBJECTIVE

The objectives of the study were to evaluate the validity of the device using spirometer data, fractional exhaled nitric oxide (FeNO), existing measures of asthma symptoms/control and health care utilization data, and to examine the sensitivity and specificity of the device in discriminating asthma cases from nonasthma cases.

METHODS

A total of 84 teens (42 teens with a current asthma diagnosis; 42 without asthma) aged between 13 and 17 years participated in the study. All participants used ADAM for 7 consecutive days during which participants with asthma completed an asthma diary two times a day. ADAM recorded the frequency of coughing for 24 hours throughout the 7-day trial. Pearson correlation and multiple regression were used to examine the relationships between ADAM data and asthma control, quality of life, and health care utilization at the time of the 7-day trial and 3 months later. A receiver operating characteristic (ROC) curve analysis was conducted to examine sensitivity and specificity based on the area under the curve (AUC) as an indicator of the device's capacity to discriminate between asthma versus nonasthma cases.

RESULTS

ADAM data (cough counts) were negatively associated with forced expiratory volume in first second of expiration (FEV1) (r=-.26, P=.05), forced vital capacity (FVC) (r=-.31, P=.02), and overall asthma control (r=-.41, P=.009) and positively associated with daily activity limitation (r=.46, P=.01), nighttime (r=.40, P=.02) and daytime symptoms (r=.38, P=.02), and health care utilization (r=.61, P<.001). Device data were also a significant predictor of asthma control (β=-.48, P=.003), quality of life (β=-.55, P=.001), and health care utilization (β=.74, P=.004) after 3 months. The ROC curve analysis for the presence of asthma diagnosis had an AUC of 0.71 (95% CI 0.58-0.84), which was significantly different from chance (χ(2) 1=9.7, P=.002), indicating the device's discriminating capacity. The optimal cutoff value of the device was 0.56 with a sensitivity of 51.3% and a specificity of 72.7%.

CONCLUSIONS

This study demonstrates validity of ADAM as a symptom-monitoring device in teens with asthma. ADAM data reflect the current status of asthma control and predict asthma morbidity and quality of life for the near future. A monitoring device such as ADAM can increase patients' awareness of the patterns of cough for early detection of worsening asthma and has the potential for preventing serious and costly future consequences of asthma.

The use of a collaborative structured methodology for the development of a multifaceted intervention programme for the management of asthma (the MIA project), tailored to the needs of children and families of South Asian origin: a community-based, participatory study

Background

Asthma is one of the most common chronic childhood illnesses in the UK. South Asian children are more likely to suffer from their asthma and be admitted to hospital. While this inequality needs to be addressed, standard behaviour-change interventions are known to be less successful in minority ethnic groups. Evidence suggests a need to enhance services provided to ethnic minority communities by developing culturally sensitive tailored interventions.

Objectives

The Management and Interventions for Asthma (MIA) project aimed to test an iterative multiphase participatory approach to intervention development underpinned by the socioecological model of health, producing an intervention-planning framework and enhancing an evidence-based understanding of asthma management in South Asian and White British children.

Design

Interviews and focus groups facilitated by community facilitators (CFs) were used to explore knowledge and perceptions of asthma among South Asian communities, children, families and healthcare professionals (HCPs). A smaller comparison group of White British families was recruited to identify aspects of asthma management that could be addressed either by generic interventions or by a tailored approach. Collaborative workshops were held to develop an intervention planning framework and to prioritise an aspect of asthma management that would be used as an exemplar for the development of the tailored, multifaceted asthma intervention programme.

Setting

The community study was based in a largely urban environment in Leicester, UK.

Participants

Participants were recruited directly from the South Asian (Indian, Pakistani and Bangladeshi) and White British communities, and through the NHS. Children were aged between 4 and 12 years, with a range of asthma severity.

Intervention development

The study had four phases. Phase 1 consisted of an evidence review of barriers and facilitators to asthma management in South Asian children. Phase 2 explored lay understandings of childhood asthma and its management among South Asian community members (n = 63). Phase 3 explored perceptions and experiences of asthma management among South Asian (n = 82) and White British families (n = 31) and HCP perspectives (n = 37). Using a modified intervention mapping approach incorporating psychological theory, phase 4 developed an intervention planning framework addressing the whole asthma pathway leading to the development of an exemplar multifaceted, integrated intervention programme called ‘ACT [Awareness, Context (cultural and organisational) and Training] on Asthma’.

Results

Data on the social patterning of perceptions of asthma and a lack of alignment between the organisation of health services, and the priorities and competencies of British South Asian communities and families were produced. Eleven key problem areas along the asthma pathway were identified. A four-arm multifaceted tailored programme, ‘ACT on Asthma’, was developed, focusing on the theme ‘getting a diagnosis’. This theme was chosen following prioritisation by families during the collaborative workshops, demonstrating the participatory, iterative, phased approach used for the intervention design.

Conclusions

The MIA study demonstrated barriers to optimal asthma management in children at the family, provider and healthcare system levels and across the whole asthma pathway. Interventions need to address each of these levels to be effective. Minority ethnic communities can be successfully engaged in collaborative intervention development with a community-focused and culturally sensitive methodology.

Future work

Further research is required to (1) assess the feasibility and effectiveness of the proposed ‘ACT on Asthma’ programme, (2) develop methods to increase active participation of children in research and service development, (3) develop and test strategies to enhance public understanding of asthma in South Asian communities and (4) identify effective means of engaging the wider family in optimising asthma management.

A systematic review of explanatory factors of barriers and facilitators to improving asthma management in South Asian children

BACKGROUND

South Asian children with asthma are less likely to receive prescriptions and more likely to suffer uncontrolled symptoms and acute asthma admissions compared with White British children. Understanding barriers are therefore vital in addressing health inequalities. We undertook a systematic review identifying explanatory factors for barriers and facilitators to asthma management in South Asian children. South Asians were defined as individuals of Indian, Pakistani or Bangladeshi descent.

METHODS

Data Sources - Medline, HMIC, EMBASE, ASSIA, Web of Science, BNI, CINAHL, PsycINFO, OpenSIGLE, CRD, Scopus, NHS Evidence, Cochrane Library, Campbell Collaboration, RCPCH, ATS, ERS, Asthma UK, Google Scholar & Asthma Guidelines (BTS, GINA, ATS, Monash, NAEPP, Singapore & New Zealand) to August 2013.Inclusion Criteria - Qualitative, quantitative or mixed methods research with primary focus on identifying explanations for barriers and/or facilitators to asthma management in South Asian children aged 0-18 years with diagnosed/suspected asthma and/or carers and/or healthcare professionals.Data Extraction - Three authors independently reviewed, selected & extracted eligible articles with disagreements resolved by research team discussion.

RESULTS

15 studies encompassing 25,755 children, 18,483 parents/carers and 239 healthcare professionals were included. Barriers and explanatory factors identified were:1. Lack of asthma knowledge in families and healthcare professionals.2. Under-use of preventer medications.3. Non-acceptance/denial of asthma.4. Over-reliance on Emergency Department management.5. Communication problems.6. Non-adherence to medication.7. Use of complementary therapies.Little facilitators regarding asthma management were identified.

CONCLUSIONS

Several key issues were identified as likely to be ethnic-specific to South Asian families, rather than a reflection of minority status: impact of parental and professional knowledge and beliefs, health service utilisation pattern explanations and the impact of prejudice and stigmatisation. Other explanations such as language barriers are not strictly ethnic specific but instead reflect a minority position.Further research is required to identify why barriers exist, the mechanisms by which they impact on asthma management and how they can be overcome. Furthermore, understanding the difference between barriers and explanations that are ethnic-specific and those that are related to being a minority will enable the application of generic system-wide interventions where ethnicity is not the issue and ethnically-tailored interventions where needed.

WHO universal definition of severe asthma

PURPOSE OF REVIEW

In 2009, an expert panel met to propose a WHO definition of asthma severity and control, and criteria for describing exacerbations and their severity, which would be globally applicable. This review addresses their findings in the context of recent literature, and assesses the usefulness of these definitions in children in particular.

RECENT FINDINGS

Severe asthma was defined by the level of current clinical control and risks as: 'Uncontrolled asthma which can result in risk of frequent severe exacerbations (or death) and/or adverse reactions to medications and/or chronic morbidity (including impaired lung function or reduced lung growth in children)'. Severe asthma includes three groups, with different public health messages and challenges: untreated severe asthma, due to undiagnosed asthma or unavailability of therapy, difficult-to-treat severe asthma (due to adherence issues, inappropriate or incorrect use of medicines, environmental triggers or co-morbidity), and treatment-resistant severe asthma, including asthma for which control is not achieved despite the highest level of recommended treatment or asthma which is controlled only with the highest level of recommended treatment.

SUMMARY

These definitions will enable more precise measurement of the burden of severe childhood asthma globally. International collaborations in epidemiological and mechanistic studies, and randomized controlled trials of treatment, will be facilitated. However, both pathophysiology and severity are influenced by a number of factors with wide global variation; international comparisons should be interpreted with caution.

Adolescents' perception of asthma symptoms and health care utilization

INTRODUCTION

Pediatric asthma is accountable for a substantial use of health care services. The purpose of this study was to systemically examine the extent to which inaccurate perception of asthma symptoms is associated with the use of health care services.

METHODS

This exploratory study included 126 adolescents with asthma who were between 13 and 20 years of age. Subjects were classified as having inaccurate symptom perception (IG); well-controlled accurate symptom perception (WCA); and poorly controlled accurate symptom perception (PCA). These groups were compared with respect to health care utilization, including emergency department (ED) visits, hospitalization, and office visits and school absenteeism in the past 3 months.

RESULTS

More adolescents in the IG group had at least one hospitalization compared with adolescents in the PCA or WCA groups (23.1% vs. 11.1% vs. 2.6%, respectively). A similar trend was seen for ED visits. Compared with the WCA group, adolescents in the IG group were nearly nine times more likely to have been hospitalized, 3.4 times more likely to have visited an ED, and four times more likely to have missed school days.

DISCUSSION

Adolescents with inaccurate symptom perception are more likely to have hospitalizations, ED visits, and missed days from school compared with those who have accurate perceptions. The findings underscore the importance of screening for perceptual accuracy of asthma symptoms and call for interventions promoting accurate symptom assessment in adolescents with asthma to ensure appropriate care.

Comparison of asthma knowledge, management, and psychological burden among parents of asthmatic children from rural and urban neighborhoods in India

INTRODUCTION

Asthma prevalence is increasing in developing countries such as India. Little is known on parental knowledge of asthma severity, management and psychosocial impact, particularly among rural dwellers. Further, it is not known whether the female asthmatic child is particularly vulnerable.

OBJECTIVE

To evaluate parental asthma knowledge and psychological impact of having an asthmatic child.

METHODS

134 consecutive caregivers were surveyed at the visit for their child's asthma exacerbation at an urban hospital in Kanpur, India between 3/2007-3/2008.

RESULTS

The child's age range was 5.7A +/- 2.7 years. 76% were urban city dwellers with significantly higher number having a college degree. 23% children had moderate to severe persistent asthma; however, only 42% were on inhaled steroids. Parental severity perception was comparable to National Heart, Lung and Blood Institute (NHLBI) classification. While 67% identified bronchoconstriction occurred with asthma, only 8.9% recognized that inflammation played a role. There was no difference in the perceived stress by area of residence with 89% reported not or only sometimes feeling stressed with having an asthmatic child. Similarly, the concern among those with a female asthmatic child did not differ with 73% of caregivers believing that asthma would not affect their daughter's future.

CONCLUSION

In an urban Indian hospital, 23% of asthmatic children had moderate to severe persistent asthma but only 9% were on controllers. Their parents were well educated, able to identify asthma severity appropriately and denied being stressed with having asthmatic children, irrespective of the gender of the child. However, their understanding of asthma pathophysiology was sub-optimal. Increased disease knowledge may lead to greater medication adherence among asthmatic children in India.

Parent-child agreement in report of nighttime respiratory symptoms and sleep disruptions and quality

INTRODUCTION

Asthma control requires assessment of nighttime symptoms and sleep disruption. Cognitive and emotional development enables most school-aged children to report nocturnal problems, but providers often rely only on parental report, potentially limiting the comprehensiveness of their assessments and their ability to support the child's emerging efforts at shared management of their illness. This study investigated parent-child concordance in report of nighttime respiratory symptoms, sleep disruption, and quality of sleep in a sample of 9- to 11-year-old children with asthma. Secondarily, similar concordance patterns in an equal number of dyads where the child was asthma free were examined to illustrate the potential influence of asthma.

METHOD

Parents and children completed 1-week diaries in their homes without confiding in one another. The probability of knowing the child's report on a specific item if the parent's report was known was assessed using contingency tables.

RESULTS

Within the asthma group, parent-child reports differed significantly across all symptoms and sleep parameters. Parents most often reported fewer symptoms and awakenings and better quality of sleep than did their child. Concordance rates were lowest for morning perceptions of tiredness, sleepiness, and alertness in both asthma and non-asthma groups.

DISCUSSION

Both parents and school-aged children with asthma need to be asked about nighttime asthma symptoms, sleep, and morning perceptions when attempting to evaluate asthma control. Assessment of sleep in all children should include parent and child reports and would benefit by the addition of objective measures.

Patterns of asthma control perception in adolescents: associations with psychosocial functioning

OBJECTIVE

The purpose was to identify and describe the patterns of asthma control perception in relation to actual symptom reports in adolescents and to compare the group with accurate control perception with those of inaccurate perception in relationship to sociodemographic characteristics, illness-related factors, and psychosocial factors.

METHODS

A sample of 126 adolescents from 13 through 20 years of age participated in the study. Patterns of control perception were constructed based on participants' rating of their perception of asthma control and self-reported asthma symptoms using Latent Class Analysis. Analyses of variance (ANOVAs) and multinomial logistic regressions were computed for group comparisons.

RESULTS

Participants were classified into four groups according to the patterns of control perception. Accurate groups were divided into either the well-controlled (62%) or the poorly-controlled group (7%), and inaccurate groups were manifested inaccuracy either with nighttime symptoms (25%) or daytime symptoms (6%). Minority participants (p < 0.001) or those with low socioeconomic status (p < 0.001) were more likely to be represented in the inaccurate group than their counterparts. The well-controlled accurate group consistently reported higher asthma-related knowledge (p = 0.02), more positive attitude toward asthma (p < 0.001), fewer barriers to self-management (p = 0.04), and higher quality of life (p < 0.001) than the inaccurate group.

CONCLUSION

This study demonstrated that accuracy of asthma control perception can be classified into four criteria based on patterns of various asthma symptoms. Adolescents' tendency toward underperception was evident. The inaccurate groups are at greater risk for psychosocial impairments. This study underscores the importance of an intervention that improves the accuracy of asthma control perception in adolescents while promoting psychosocial well-being among adolescents with inaccurate perception.
