A qualitative study of parent perspectives on barriers,facilitators and expectations for school asthma care among urban,African-American children

Objectives: Minority children experience the disproportionate burden of asthma and its consequences. Studies suggest ethnic groups may experience asthma differently with varied perceptions and expectations among parents of African-American and Latino children. Because parents coordinate asthma care with the school, where children spend a significant amount of their day, this study’s goal was to determine parents’ perspectives on school asthma management. Methods: Focus groups were conducted with parents of children with asthma at four urban schools whose student population is predominantly African-American. A semi-structured guide was utilized focusing on barriers, facilitators and expectations for asthma care at school. Grounded theory principles were applied in this study. Results: Twenty-two parents (91% females) representing 13 elementary and 10 middle school children with asthma (61% boys) participated in four focus groups. Most children (87%) had persistent asthma. The identified barriers to effective school-based asthma care included limited awareness of children with asthma by teachers/staff, communication issues (e.g. school/parent, within school), inadequate education and lack of management plans or systems in place. In contrast, the identified facilitators included steps that fostered education, communication and awareness, as supported by management plans and parent initiative. Parents described their expectations for increased communication and education about asthma, better systems for identifying children with asthma, and a trained asthma point person for school-based asthma care. Conclusions: Parents of children with asthma identified important barriers, facilitators and expectations that must be considered to advance school asthma management. Improved school-based asthma care could lead to better health and academic outcomes.     

Using the theoretical domains framework to identify barriers and enablers to pediatric asthma management in primary care settings

Objectives: This study aimed to apply a theory-based approach to identify barriers and enablers to implementing the Alberta Primary Care Asthma Pediatric Pathway (PCAPP) into clinical practice. Phase 1 included an assessment of assumptions underlying the intervention from the perspectives of the developers. Phase 2 determined the perceived barriers and enablers for: 1) primary care physicians' prescribing practices, 2) allied health care professionals' provision of asthma education to parents, and 3) children and parents' adherence to their treatment plans. Methods: Interviews were conducted with 35 individuals who reside in Alberta, Canada. Phase 1 included three developers. Phase 2 included 11 primary care physicians, 10 allied health care professionals, and 11 parents of children with asthma. Phase 2 interviews were based on the 14 domains of the Theoretical Domains Framework (TDF). Transcribed interviews were analyzed using a directed content analysis. Key assumptions by the developers about the intervention, and beliefs by others about the barriers and enablers of the targeted behaviors were identified. Results: Eight TDF domains mapped onto the assumptions of the pathway as described by the intervention developers. Interviews with health care professionals and parents identified nine TDF domains that influenced the targeted behaviors: knowledge, skills, beliefs about capabilities, social/professional role and identity, beliefs about consequences, environmental context and resources, behavioral regulation, social influences, and emotions. Conclusions: Barriers and enablers perceived by health care professionals and parents that influenced asthma management will inform the optimization of the PCAPP prior to its evaluation.     

Parent report and electronic medical record agreement on asthma education provided and children’s tobacco smoke exposure

Abstract

Objective: To examine the concordance between parent report and electronic medical record documentation of asthma health education provided during a single clinic visit and second-hand tobacco smoke exposure among children with asthma. Methods: Parents of children with asthma were recruited from two types of clinics using different electronic medical record systems: asthma-specialty or general pediatric health department clinics. After their child’s outpatient visit, parents were interviewed by trained study staff. Interview data were compared to electronic medical records for agreement in five categories of asthma health education and for the child’s environmental tobacco smoke exposure. Kappa statistics were used to identify strength of agreement. Chi square and t-tests were used to examine differences between clinic types. Results: Of 255 parents participating in the study 90.6% were African American and 96.1% were female. Agreement was poor across all clinics but was higher within the asthma specialty clinics than the health department clinics for smoke exposure (κ?=?0.410 versus 0.205), asthma diagnosis/disease process (κ?=?0.213 versus ?0.016) and devices reviewed (κ?=?0.253 versus ?0.089) with parents generally reporting more education provided. For the 203 children with complete medical records, 40.5% did not have any documentation regarding smoking exposure in the home and 85.2% did not have any documentation regarding exposure elsewhere. Conclusions: We found low concordance between the parent’s report and the electronic medical record for smoke exposure and asthma education provided. Un- or under-documented smoke exposure and health education have the potential to affect continuity of care for pediatric patients with asthma.     

Disparities in emergency department visits in American children with asthma: 2006–2010

Objective: This article was to examine the trends in emergency department (ED) visits for asthma among American children in 2006–2010 across sociodemographic factors, parental smoking status, and children's body weight status. Methods: We analyzed 5,535 children aged 2–17 years with current asthma in the Asthma Call-Back Survey in 2006–2010. Multivariate log binomial regression was used to examine the disparities of ED visits by demographics, socioeconomic status, parental smoking status, children's body weight status, and the level of asthma control. We controlled for average state-level air pollutants. Prevalence ratios (PRs) and 95% confidence intervals (CIs) were reported. Results: Minority children with current asthma had higher risks of ED visits compared with white children in 2009 and 2010, e.g., the PR (95% CI) for black children in 2009 was 3.64 (1.79, 7.41). Children who had current asthma and more highly educated parents experienced a higher risk of ED visits in 2007 (PRs [95% CI] = 2.15 [1.02, 4.53] and 2.97 [1.29, 6.83] for children with some college or college-graduated parents), but not significant in other years. Children with uncontrolled asthma were significantly more likely to visit the ED in 2008 (PRs [95% CI] = 2.79 [1.44, 5.41] and 6.96 [3.55, 13.64] for not-well-controlled and very poorly controlled children with asthma). Conclusions: Minority children with current asthma or children with uncontrolled asthma were more likely to visit EDs for asthma treatment. However, the disparities in ED visits across sociodemographics, health status, or asthma control vary in scale and significance across time. More research is needed to explain these differences.     

Sheltered versus nonsheltered homeless women

OBJECTIVE: To contrast sociodemographic characteristics, physical and mental health status, substance use, sexual behaviors, victimization, and utilization of health services between homeless women residing in sheltered and nonsheltered environments. DESIGN: Cross-sectional survey. A structured scale was used to measure mental health status. Physical health status, substance use, sexual behavior, history of adult victimization, and health services utilization were measured by content-specific items. SETTING: Shelters (N=47) and outdoor locations in Los Angeles. PARTICIPANTS: One thousand fifty-one homeless women. RESULTS: Homeless women living on the streets were more likely than sheltered women to be white and longer-term homeless. Controlling for sociodemographic characteristics, multiple logistic regression analyses revealed that unsheltered women had over 3 times greater odds of fair or poor physical health, and over 12 times greater odds of poor mental health than sheltered homeless women. They were also more likely than sheltered women to report using alcohol or noninjection drugs, to have multiple sexual partners, and to have a history of physical assault. About half of the overall sample reported utilization of a variety of health services; however, unsheltered homeless women were less likely to utilize all of the health services that were assessed, including drug treatment. CONCLUSIONS: There is a critical need for aggressive outreach programs that provide mental health services and substance abuse treatment for homeless women on the streets. Comprehensive services that also include medical care, family planning, violence prevention, and behavioral risk reduction may be particularly valuable for homeless women, especially those living in unsheltered environments. This research was supported by the National Institute on Drug Abuse, grants DA06719 and DA01070. Dr. Gelberg is a Robert Wood Johnson Generalist and Physician Faculty Scholar.     

Experiences of living with asthma – a focus group study with adolescents and parents of children with asthma

Objective: The goal for asthma treatment is that every individual, so far as possible, shall live without symptoms and exacerbations. Patients and health care professionals sometimes have different perceptions of what is important for achieving good quality of life. This work aims to describe the experiences among adolescents as well as those of parents with young children living with asthma. Methods: Four focus group interviews were performed, two with parents of young children and two with adolescents. The data were qualitatively analyzed, using Systematic Text Condensation. Result: Three themes relevant to the participants’ experiences of living with asthma were presented; strategies, frustrations and expectations. The adolescents wanted to be like their peers and developed their own strategies for self-management of asthma, which included not always taking medication as prescribed. The parents emphasized frustration regarding not being believed, lack of understanding feelings of loneliness, or anxiety. One identified expectation was that the participants wanted to be met with competence and understanding in asthma care from health care professionals. Another expectation expressed among parents was that teachers in nursery and primary schools should have more knowledge and understanding on how to care for children with asthma. Conclusion: Living with asthma leads to developing personal strategies in self-management of asthma. Moreover both parents and adolescents had expectations of being met by competent and understanding health care professionals. Developing a partnership between patients and health care professionals could be a successful way to improve the care of patients with asthma.     

Path to health asthma study: A survey of pediatric asthma in an urban community

Objective: Minority children with asthma who live in low-income urban communities bear a disproportionate burden of the disease. This study explores the perceived health care needs related to asthma care, identifies asthma triggers, potential barriers to care, and assesses the need for additional community resources. Methods: We conducted a cross-sectional survey of Hispanic and African American adults (n = 53) who take care of a child with asthma and live in an urban community of North Philadelphia. Input from community leaders was obtained in the development the survey tool resulting in a unique ‘community-centric’ questionnaire. The survey was also available in Spanish. All surveys were conducted in the community setting. Results: Variables were used to measure asthma severity and triggers. Children were categorized with intermittent (n = 24, 45.3%), mild persistent (n = 13, 24.5%), or moderate-to-severe persistent asthma (n = 16, 30.2%). Most children with persistent asthma were enrolled under Medicaid or CHIP (n = 24, p = 0.011) and reflected a low-income socioeconomic status. Persistent asthma was found to be associated with most triggers: pets, dust mites, mice, mold, and cockroaches. There was no significant association between environmental tobacco smoke and persistent asthma. Children with persistent asthma and 2 or more triggers were more likely to be hospitalized and go to the Emergency Department. Conclusion: Urban minority children living in low-income communities face neighborhood-specific asthma triggers and challenges to care. Studies conducted in urban neighborhoods, with collaboration from community members, will highlight the need of comprehensive services to account for community-centric social determinants.     

Exploring the barriers and incentive architecture for modifying smoke exposures among asthmatics

Background: The socio-structural barriers for reducing secondhand smoke exposure (SHSe) among children with asthma may be insurmountable for low-income caregivers. Health promoting financial incentives (HPFIs) are increasingly being used in the adult population to motivate and sustain tobacco-reduction behaviors. We assessed barriers to SHSe reduction and means to overcome them through the design of an HPFI-based, caregiver-targeted SHSe reduction study. Methods: Using a mixed-methods design, we conducted semi-structured in-depth interviews among low-income primary caregivers of children with asthma residing in Baltimore City. Quantitative data using an online survey were used to augment interview findings. Results: Home smoking restrictions were a frequently referenced strategy for decreasing SHSe, but interviewees (n?=?22) described the complex social pressures that undermine reduction efforts. Caregivers redirected conversations from broadly implemented smoking bans towards targeted reduction strategies among mothers and members of their social network who are active smokers. Participants converged on the notion that sustainable SHSe reduction strategies are realizable only for mothers who are active smokers, possess high self-efficacy and social structures that promote cessation. Survey data (n?=?56) clarified the multiple contexts that underlie pediatric SHSe and preferred HPFI architecture that included fixed, recurrent payments contingent on reduced nicotine biomarkers and completion of basic asthma education classes. Conclusions: Based on the combined analyses, we envision testing a HPFI-based study design whose optimal target population included low-income caregivers and members of their social network where incentives are tied to pediatric biomarkers and asthma education—an integrated approach that has not yet been used in pediatric tobacco studies.     

Caregiver knowledge and its relationship to asthma control among children in Saudi Arabia

Objective: The objective of this study was to examine caregiver responses to individual questions of the asthma knowledge questionnaire and to compare the prevalence of uncontrolled asthma among children according to caregiver responses (correct vs. incorrect). Methods: We conducted an analytical cross-sectional study among 158 children with asthma aged 4–11 who were attending the pediatric primary care clinic of the King Khalid University Hospital in Riyadh, Saudi Arabia. The asthma knowledge questionnaire for use with parents or guardians of children with asthma was used to measure the knowledge of caregivers. Asthma control in the children was measured using an Arabic version of the childhood asthma control test. Pearson’s chi-square or Fisher’s exact tests were used to compare the prevalence of uncontrolled asthma according to the caregivers’ responses. Results: This study showed substantial gaps in knowledge among caregivers of children with asthma. The answer to only one of 17 questions was well known (86.1%); this question involved the harm of smoking near a child with asthma. Answers on 11 of 17 questions were significantly (p?Conclusions: Although innovations are needed to help patients improve their adherence to treatment and to effectively utilize the benefits of contemporary asthma medications, we observe substantial knowledge-related problems in the asthma management of children in Saudi Arabia.     

Reducing Home Triggers for Asthma: The Latino Community Health Worker Approach

This study assessed the ability of a community health worker asthma intervention to change home asthma triggers. A total of 56 children and 47 adults with asthma were enrolled. Home trigger scores for the children averaged 2.8 at the initial home visit and then 2.3, 2.1, and 2.0 at 3, 6, and 12 months. Home trigger scores for the adults showed a similar trend. Every home visit was associated with a 0.32 reduction in home trigger score (p < 0.01) for children and a 0.41 reduction (p < 0.01) for adults. This intervention shows promise as a way to reduce asthma triggers in urban low-income Latino communities.     

The effects of low-level environmental tobacco smoke exposure on pulmonary function tests in preschool children with asthma

Objectives: Though parents of children with asthma smoke, they often avoid smoking in their homes or near their children, thus limiting exposure. It is not known if such low-level environmental tobacco smoke (ETS) results in measurable exposure or affects lung function. The objectives of this study were to measure urinary cotinine in preschool children with asthma, and to examine the relationship between low-level ETS exposure and pulmonary function tests (PFTs). Methods: Preschool children with asthma were enrolled. Parents completed questionnaires on ETS exposure and asthma control, urinary cotinine concentrations were measured and PFTs were compared between subjects with and without recent ETS exposure. Results: Forty one subjects were enrolled. All parents denied smoking in their home within the last 2 weeks, but 14 (34%) parents admitted to smoking outside their homes or away from their children. Fifteen (37%; 95%CI: 23–53) of the children had urinary cotinine levels ≥1?ng/ml, of which seven (17%; 95%CI: 8–32) had levels ≥5?ng/ml. FEV₁ and FEV_0.5 were lower in subjects with a urinary cotinine level ≥5?ng/ml as compared to those with levels <1?ng/ml or between 1 and 5?ng/ml; both at baseline and after inhalation of albuterol. Five of seven subjects with urinary cotinine levels ≥5?ng/ml had FEV_0.5 less than 65% of predicted values. There were no significant differences in IOS measures. Conclusions: Despite parental denial of smoking near their children, preschool children may be exposed to ETS. Such low-level ETS exposure may affect lung function, possibly in a dose-dependent manner.     

Assessing asthma control and associated risk factors among persons with current asthma – findings from the child and adult Asthma Call-back Survey

Introduction: Monitoring the level of asthma control is important in determining the effectiveness of current treatment which may decrease the frequency and intensity of symptoms and functional limitations. Uncontrolled asthma has been associated with decreased quality of life and increased health care use. The objectives of this study were to assess the level of asthma control and identify related risk factors among persons with current asthma. Methods: Using the 2006 to 2010 BRFSS child and adult Asthma Call-back Survey, asthma control was classified as well-controlled or uncontrolled (not-well-controlled or very-poorly-controlled) using three impairment measures: daytime symptoms, night-time symptoms, and taking short-acting β2-agonists for symptom control. Multivariate logistic regression identified predictors of asthma control. Results: Fifty percent of adults and 38.4% of children with current asthma had uncontrolled asthma. About 63% of children and 53% of adults with uncontrolled asthma were on long-term asthma control medications. Among children, uncontrolled asthma was significantly associated with being younger than 5 years, having annual household income <$15?000, and reporting cost as barriers to medical care. Among adults, it was significantly associated with being 45 years or older, having annual household income of <$25?000, being “other” race, having less than a 4-year college degree, being a current or former smoker, reporting cost as barriers, being obese, and having chronic obstructive pulmonary disease or depression. Conclusion: Identifying and targeting modifiable predictors of uncontrolled asthma (low educational attainment, low income, cigarette smoking, and co-morbid conditions including obesity and depression) could improve asthma control.     

Student perspectives on asthma management in schools: a mixed-methods study examining experiences,facilitators, and barriers to care

Objective: Children spend nearly a third of their day at school, making it a critical point of intervention for those with asthma. This study aimed to illuminate minority students’ experiences with asthma at school and perceptions of facilitators and barriers to care. Methods: A mixed-methods study was conducted with elementary students with asthma. Participants completed a 24-question survey, drawing exercise to depict experiences caring for their asthma at school, and focus group discussion. Drawings were analyzed for narrative and pictorial themes. Discussions were audio-recorded, transcribed, and independently coded for themes. Results: Fifteen children with asthma (8–11?years) participated from two Chicago schools with predominately African-American populations. Most students (79%) indicated they had control of asthma at school, while 85% identified asthma as a problem when exercising. Half (53%) received help with asthma care at school. Drawings depicted cooperative management with adults or peers and the central role of inhalers as part of everyday asthma care in school. Finally, focus groups produced six key themes within the domains of facilitators: 1) support of others, 2) self-efficacy; 3) perception of being normal; and barriers: 4) lack of support from others; 5) difficulty accessing inhaler; 6) perception of being different. Conclusions: This study suggests asthma care plays an important role in students’ school experiences. Stigma around inhaler use, lack of concern by school staff, and limited access to medications remain as barriers to school-based asthma management. Although facilitators, such as support from teachers and peers, do exist, future interventions must address existing barriers.     

Asthma in schoolchildren in Monroe county,Florida: school-based needs assessment

Objectives: Asthma is the most common chronic pediatric condition (14%) and the leading cause of school absenteeism in the USA. However, little is known about asthma prevalence and distribution in schoolchildren in the Florida Keys region (Monroe County). Thus, the objectives of this study were to assess asthma prevalence, symptoms, cost and distribution in schoolchildren in the Florida Keys region and to pinpoint where asthma management services are most needed. Methods: Cross-sectional survey data on asthma prevalence, symptoms and socio-demographics was collected and analyzed by race, sex, grade and zip code. A total of 2313 parents of schoolchildren in the Florida Keys completed the adapted Harlem Empowerment Zone Asthma Initiative Questionnaire. The questionnaire was distributed to school principals, who sent them home with students to be filled out by parents or caregivers. We also analyzed data from the online Monroe County 2012 Florida Youth Tobacco Survey, the 2011 Florida CHARTS, the Medical Expenditures Panel Survey, and emergency departments (ED). Data were analyzed by race, sex, and grade. Results: In total 14.5% of respondents had been told their child had asthma and 9.6% reported their child had wheezing in the last 12 months. The prevalence was higher in the Lower Keys and Key West regions. Parents from households where anyone smoked cigarettes (OR 1.52, 95% CI 1.11–2.09) and those who had a male child (1.53, 1.17–2.00) more often reported that their child had asthma. The rate of asthma-related ED visits for Black non-Hispanic schoolchildren (1202 per 100?000) was substantially higher than the numbers for White (250.2 per 100?000) and Hispanic schoolchildren (325.1 per 100?000). Most of the direct cost of asthma was concentrated in children in grades four through seven ($1236.02–$2147.02 per child). Conclusions: The asthma prevalence in a sample of schoolchildren in the Florida Keys region was comparable to the nationwide prevalence. Black non-Hispanic schoolchildren had more asthma-related ED visits that White and Hispanic schoolchildren. Most of the direct cost of asthma is concentrated in children in late elementary through early middle school grades. Interventions are needed, particularly targeting Black schoolchildren in late elementary through early middle school grades in Lower Keys and Key West region.     

Concordance among children,caregivers, and clinicians on barriers to controller medication use

Objective: While much research has addressed asthma medication adherence, few have combined quantitative and qualitative data, and none has addressed the triad of child, caregiver, and clinician simultaneously. This study assessed, with mixed methods, barriers to medication adherence within this triad. Methods: We conducted interviews with publicly-insured children with asthma, their caregivers, and their primary-care clinicians. Children (7–17 years) had been prescribed daily inhaled corticosteroids and visited the ED for asthma (past year). Participants answered open-ended and survey questions, rating suggested barriers to medication use (never vs. ever a barrier). McNemar's tests compared report of barriers by each group (children, caregivers, clinicians), and assessed concordance within triads. Results: Fifty child–caregiver dyads participated (34 clinicians). Children (40% female; median age 10 years) had mostly non-Hispanic black (90%) caregivers with less than or equal to high-school education (68%). For barriers, children and clinicians were more likely than caregivers to report medications running out. Clinicians were also more likely to cite controllers being a “pain to take” (vs. children) and forgetfulness (vs. caregivers) (all p < .05). There was a lack of within-triad concordance regarding barriers to adherence, especially regarding medication running out, worrying about taking a daily medication, and medication being a pain to take. Qualitative data revealed themes of competing priorities, home routines, and division of responsibility as prominent contributors to medication adherence. Conclusions: There was significant disagreement among children, caregivers, and clinicians regarding barriers to daily use of asthma medications. To tailor asthma management conversations, clinicians should understand family-specific barriers and child–caregiver disagreements.     

Low-level environmental tobacco smoke exposure and inflammatory biomarkers in children with asthma

Objective: The effects of low-level environmental tobacco smoke (ETS) exposure, on asthma control, lung function and inflammatory biomarkers in children with asthma have not been well studied. The objective of the study was to assess ETS exposure in school-age children with asthma whose parents either deny smoking or only smoke outside the home, and to assess the impact of low-level ETS exposure on asthma control, spirometry and inflammatory biomarkers. Methods: Forty patients age 8–18 years with well-controlled, mild-to-moderate persistent asthma treated with either inhaled corticosteroids (ICS) or montelukast were enrolled. Subjects completed an age-appropriate Asthma Control Test and a smoke exposure questionnaire, and exhaled nitric oxide (FeNO), spirometry, urinary cotinine and leukotriene E₄ (LTE₄) were measured. ETS-exposed and unexposed groups were compared. Results: Only one parent reported smoking in the home, yet 28 (70%) subjects had urinary cotinine levels ≥1?ng/ml, suggesting ETS exposure. Seven subjects (18%) had FeNO levels >25parts per billion, six of whom were in the ETS-exposed group. In the ICS-treated subjects, but not in the montelukast-treated subjects, ETS exposure was associated with higher urinary LTE₄, p?=?0.04, but had no effect on asthma control, forced expiratory volume in 1?s or FeNO. Conclusions: A majority of school-age children with persistent asthma may be exposed to ETS, as measured by urinary cotinine, even if their parents insist they don’t smoke in the home. Urinary LTE₄ was higher in the ETS-exposed children treated with ICS, but not in children treated with montelukast.     

Evaluation,modification and validation of a set of asthma illustrations in children with chronic asthma in the emergency department

OBJECTIVES:

To test, modify and validate a set of illustrations depicting different levels of asthma control and common asthma triggers in pediatric patients (and/or their parents) with chronic asthma who presented to the emergency department at the Children’s Hospital of Eastern Ontario, Ottawa, Ontario.

METHODS:

Semistructured interviews using guessability and translucency questionnaires tested the comprehensibility of 15 illustrations depicting different levels of asthma control and common asthma triggers in children 10 to 17 years of age, and parents of children one to nine years of age who presented to the emergency department. Illustrations with an overall guessability score <80% and/or translucency median score <6, were reviewed by the study team and modified by the study’s graphic designer. Modifications were made based on key concepts identified by study participants.

RESULTS:

A total of 80 patients were interviewed. Seven of the original 15 illustrations (47%) required modifications to obtain the prespecified guessability and translucency goals.

CONCLUSION:

The authors successfully developed, modified and validated a set of 15 illustrations representing different levels of asthma control and common asthma triggers.

PRACTICE IMPLICATIONS:

These illustrations will be incorporated into a child-friendly asthma action plan that enables the child to be involved in his or her asthma self-management care.     

Factors Associated with Asthma Control

The aim of this study was to evaluate which factors are associated with asthma control experienced by asthma patients. In a cross-sectional study patients aged 16–60 years with mild to moderate asthma were selected. The influence of the following factors on asthma control was studied in a multivariate model: age, gender, socioeconomic status, smoking, perceived hyperresponsiveness (PHR, responding with asthma symptoms to one or more triggers), allergy (Phadiatop®), long-acting bronchodilating agents, and inhaled corticosteroids. Asthma control was measured by means of the Asthma Control Questionnaire© (ACQ) as developed by Juniper. Forced expiratory volume in 1 second (FEV₁) was measured by means of a portable spirometer. In this study with 311 patients, mean ACQ score was 1.39 (range 0–4.43). A stepwise backward linear regression analysis showed that low socioeconomic status (beta 0.425; p = 0.001), current smoking (beta 0.555; p < 0.001), high dose of inhaled corticosteroids (beta 0.364; p = 0.04) and perceived hyperresponsiveness for increasing number of different triggers (PHR for 1 trigger beta 0.833; p = 0.03; 2 triggers beta 0.810; p = 0.03; 3 triggers beta 0.995; p = 0.01; 4 triggers beta 1.131; p = 0.002; 5 triggers beta 1.182; p = 0.002) are independent predictors for poorer asthma control. Beside treatment with medication, stopping smoking and avoidance of triggers are factors, which may have a high impact on asthma control.     

Spacers versus nebulizers in treatment of acute asthma – a prospective randomized study in preschool children

Objective: To compare administration of bronchodilators by nebulizers with delivery by metered dose inhalers (MDIs) with spacers and to evaluate the clinical effect of the treatment of acute asthma in preschool children. Methods: A prospective randomized clinical trial in a pediatric emergency department (PED). Preschool children who were admitted for virus induced wheezing or acute asthma exacerbation were randomly allocated to receive bronchodilator treatment by nebulizer or by metered dose inhaler. The accompanying parents completed a questionnaire. Results: The length of stay in the PED and the hospitalization rate were similar and no difference was seen in the parents' view of ease of use and device acceptance. Baseline data were similar for both groups apart from the family history of asthma and atopic disease that was greater in the nebulizer group. No significant differences were seen in heart rate, respiratory rate and oxygen saturation at baseline and after the treatment. According to the parents 40% of the participants had asthma diagnosis though up to 66% had some kind of asthma medication. Conclusions: Our data suggests that MDIs with spacers are at least as effective as nebulizers in the delivery of beta agonists to treat preschool children with virus induced wheezing or acute exacerbations of asthma in the PED. Parents may underestimate the gravity of their children's asthma. It is mandatory to provide adequate information to the staff and parents in order to treat pediatric acute asthma successfully.
