Abstract
OBJECTIVE Asthma education has been shown to improve asthma control. Our goal was to evaluate the efficacy of asthma education on the frequency of utilization of health-care services, lung function results, degree of asthma severity, and quality of life (QOL) level in children with asthma. METHODS A single-arm prospective interventional trial was conducted in a tertiary facility. Thirty children with asthma and their parents were recruited for the research. Following an assessment of the participants' and caregivers' knowledge about asthma using an asthma knowledge questionnaire, degree of asthma control using asthma control test, inhaler technique using standardized inhaler technique checklists, and QOL using pediatric asthma QOL questionnaires, they participated in a three-month education program in the form of monthly live interactive sessions followed by weekly phone interviews. Measures taken before and after the intervention were compared. RESULTS The educational intervention improved asthma control dramatically including daytime asthma symptoms, night awakenings, and frequency of use of short-acting beta2- adrenergic receptor agonists. Furthermore, the number of emergency department visits and hospitalizations fell considerably after the intervention (p < 0.001 for all). Asthma education was also linked to better inhalation technique and lung function (p < 0.001). Furthermore, all quality-of-life measures increased (p < 0.001 for all). CONCLUSIONS Implementing an asthma education program that included both children with asthma and their parents improved asthma control levels, lung function measures, and overall quality of life. Furthermore, it increased asthma awareness, decreased the use of health-care resources, and reduced asthma severity, resulting in better asthma management.

Abstract
AbstractRacial inequities in asthma care are evolving as a recognized factor in long-standing inequities in asthma outcomes (e.g., hospitalization and mortality). Little research has been conducted regarding the presence or absence of racial inequities among patients seen in asthma specialist settings, this is an important area of future research given that asthma specialist care is recommended for patients experiencing the poor asthma outcomes disproportionately experienced by Black and Hispanic patients. This study provides a systematic review of racial asthma care inequities in asthma epidemiology, clinical assessment, medication prescription, and asthma specialist referral practices.

What Parents Want Doctors to Know: Responses to an Open-Ended Item on an Asthma Questionnaire. Acad Pediatr 2022; 22:657-666. [PMID: 34800723 DOI: 10.1016/j.acap.2021.11.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/26/2021] [Revised: 11/08/2021] [Accepted: 11/09/2021] [Indexed: 11/01/2022]
Abstract
OBJECTIVE Unstructured parental comments could solicit important information about children's asthma, yet are rarely captured in clinical asthma questionnaires. This mixed-methods study describes parents' written responses to an open-ended question in a validated asthma questionnaire. METHODS The Pediatric Asthma Control and Communication Instrument (PACCI) asthma questionnaire was administered to parents of children with asthma symptoms presenting to 48 pediatric primary care offices (PPCP), 1 pediatric pulmonology office, and 1 emergency department (ED). Responses to the question, "Please write down any concern or anything else you would like your doctor to know about your child's asthma" were analyzed using a phenomenological approach until thematic saturation was achieved for each site. Logistic regressions tested whether sociodemographic and clinical characteristics were associated with responding to the open-ended question. RESULTS Of 7,988 parents who completed the PACCI, 954 (12%) responded to the open-ended question-2% in PPCP, 31% in the ED, and 50% in the pulmonary setting. More severe asthma was associated with higher odds of responding (odds ratio, 2.01; 95% confidence interval, 1.42-2.84). Based on responses provided, we identified 3 communication types: 1) clarifying symptoms, 2) asking questions, and 3) communicating distress. Responses also covered 5 asthma-related themes: 1) diagnostic uncertainty, 2) understanding asthma etiology and prognosis, 3) medication management, 4) impact on child function, and 5) personal asthma characteristics. CONCLUSION Parents of children with severe asthma provided clarifying details, asked questions, and relayed health concerns and distress. None of these topics may be easily captured by closed-ended asthma questionnaires.

Development of the Asthma Impairment and Risk Questionnaire (AIRQ): A Composite Control Measure. THE JOURNAL OF ALLERGY AND CLINICAL IMMUNOLOGY-IN PRACTICE 2020; 8:2263-2274.e5. [PMID: 32387166 DOI: 10.1016/j.jaip.2020.02.042] [Citation(s) in RCA: 14] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Subscribe] [Scholar Register] [Received: 09/13/2019] [Revised: 02/27/2020] [Accepted: 02/28/2020] [Indexed: 02/08/2023]
Abstract
BACKGROUND Asthma exacerbation risk increases with worsening asthma control. Prevailing numerical control tools evaluate only current symptom impairment despite the importance of also assessing risk based on exacerbation history. An easy-to-use questionnaire addressing impairment and risk domains of control is needed. OBJECTIVE To validate a composite asthma control tool that includes impairment and risk assessments (Asthma Impairment and Risk Questionnaire [AIRQ]). METHODS Four-hundred forty-two patients aged ≥12 years with physician-diagnosed asthma who were followed in specialty practices completed 15 impairment and risk questions with dichotomized yes/no responses. Patients spanned all Global Initiative for Asthma severities and were classified as well-controlled, not well-controlled, or very poorly controlled according to a standard of Asthma Control Test (ACT) score plus prior-year exacerbations. Logistic regression analyses identified questions with the greatest predictive validity to discriminate among patients and determine cut points for these 3 classifications. RESULTS The final AIRQ comprises 10 equally weighted yes/no impairment and risk questions. The final 10-item models yielded receiver operating characteristic curves of 0.94 to identify well-controlled versus not well-/very poorly controlled and 0.93 to identify well-/not well-controlled versus very poorly controlled asthma, as reflected by the ACT plus prior-year exacerbations standard. Cut points of 0-1, 2-4, and 5-10 best represented well-, not well-, and very poorly controlled asthma. CONCLUSIONS AIRQ is a rigorously validated composite measure designed to identify adults and adolescents with varying degrees of asthma control. Ongoing investigations will determine test-retest reliability, responsiveness to change, and predictive ability for future exacerbations.

Abstract
BACKGROUND It is unknown whether caregiver perception of a child's asthma control, independent of guideline-based asthma control assessment, is a predictor of future acute visits. OBJECTIVE To determine whether caregiver-reported asthma control is an indicator of future risk of acute visit. METHODS Two study populations of low-income, minority 5- to 17-year-old children with persistent asthma were included. Questionnaires administered at baseline and at 3, 6, 9, and 12 months captured symptoms, short-acting β-agonist use, acute visits in the previous 3 months, and caregiver-reported asthma control. Well-controlled, not well-controlled, and very poorly controlled asthma were defined using National Asthma Education and Prevention Program guideline-based assessment. Relationships between caregiver-reported control and acute visits in the subsequent 3 months were examined. RESULTS At baseline, both populations were predominantly black/African American (91% and 79%) with public insurance (85% and 88%) and very poorly controlled asthma (47% and 50%). In both populations, most caregivers reported that their child's asthma was well controlled (73% and 69%). In both populations, participants whose caregivers reported that their child had uncontrolled asthma had greater odds of having an acute visit in the following 3 months as compared with participants whose caregivers reported that their child's asthma was well controlled, independent of guideline-based control, age, sex, race, controller medication, insurance, and atopy (odds ratio [95% CI], 2.4 [1.4-4.2] and 1.6 [1.1-2.4]). CONCLUSIONS Among predominantly low-income minority children with asthma, caregiver-reported asthma control may provide information about the risk of future acute visit for asthma that is complementary to guideline-based control assessment.

Abstract
BACKGROUND The National Institutes of Health guidelines recommend questionnaires to assess asthma control, but there are few self-reported asthma morbidity surveys validated among urban, African American, Hispanic, and/or poor adolescents. The Asthma Control and Communication Instrument (ACCI) is a 12-item self-reported questionnaire previously validated among a diverse adult population, but not among adolescents. OBJECTIVE To assess the ability of the ACCI to accurately describe asthma control in an urban adolescent population. METHODS Between November 13, 2014, and March 2, 2017, we collected information using the ACCI, the Asthma Control Test, the Pediatric Asthma Quality of Life Questionnaire, and lung function among adolescents enrolled in a school-based asthma intervention study. The ACCI measure of asthma control was validated by evaluating accuracy (on the basis of receiver operating characteristic curve), internal reliability, and concurrent and discriminative validity. RESULTS We collected information on 280 adolescents (mean age, 13.4 years; 56% males; and 51% African American). ACCI control showed good internal reliability and strong concurrent and discriminative validity with the Asthma Control Test and the Pediatric Asthma Quality of Life Questionnaire. The accuracy of the ACCI in classifying adolescents with uncontrolled asthma was good (area under the curve, 0.83; 95% CI, 0.79-0.88). CONCLUSION The ACCI, a clinical tool developed to assist communication about asthma control, has demonstrated strong construct validity as a self-reported questionnaire within an urban, African American, and Hispanic sample of adolescents. It has the potential to assist in the assessment of asthma control in urban, minority, and/or poor adolescents.

Abstract
BACKGROUND Long-term physical conditions affect 10% to 12% of children and adolescents worldwide; these individuals are at greater risk of developing psychological problems, particularly anxiety and depression. Access to face-to-face treatment for such problems is often limited, and available interventions usually have not been tested with this population. As technology improves, e-health interventions (delivered via digital means, such as computers and smart phones and ranging from simple text-based programmes through to multimedia and interactive programmes, serious games, virtual reality and biofeedback programmes) offer a potential solution to address the psychological needs of this group of young people. OBJECTIVES To assess the effectiveness of e-health interventions in comparison with attention placebos, psychological placebos, treatment as usual, waiting-list controls, or non-psychological treatments for treating anxiety and depression in children and adolescents with long-term physical conditions. SEARCH METHODS We searched the Cochrane Common Mental Disorders Group's Controlled Trials Register (CCMDTR to May 2016), the Cochrane Central Register of Controlled Trials (CENTRAL) (Issue 8, 2017), Web of Science (1900 - 18 August 2016, updated 31 August 2017) and Ovid MEDLINE, Embase, PsycINFO (cross-search 2016 to 18 Aug 2017). We hand-searched relevant conference proceedings, reference lists of included articles, and the grey literature to May 2016. We also searched international trial registries to identify unpublished or ongoing trials. SELECTION CRITERIA We included randomised controlled trials (RCTs), cluster-randomised trials, and cross-over trials of e-health interventions for treating any type of long-term physical condition in children and adolescents (aged 0 to 18 years), and that measured changes in symptoms or diagnoses of anxiety, depression, or subthreshold depression. We defined long-term physical conditions as those that were more than three-months' duration. We assessed symptoms of anxiety and depression using patient- or clinician-administered validated rating scales based on DSM III, IV or 5 (American Psychological Association 2013), or ICD 9 or 10 criteria (World Health Organization 1992). Formal depressive and anxiety disorders were diagnosed using structured clinical interviews. Attention placebo, treatment as usual, waiting list, psychological placebo, and other non-psychological therapies were eligible comparators. DATA COLLECTION AND ANALYSIS Two review authors independently reviewed titles, abstracts, and full-text articles; discrepancies were resolved through discussion or addressed by a third author. When available, we used odds ratio (OR) to compare dichotomous data and standardised mean differences (SMD) to analyse continuous data, both with 95% confidence intervals (CI). We undertook meta-analysis when treatments, participants, and the underlying clinical question were adequately similar. Otherwise, we undertook a narrative analysis. MAIN RESULTS We included five trials of three interventions (Breathe Easier Online, Web-MAP, and multimodal cognitive behavioural therapy (CBT)), which included 463 participants aged 10 to 18 years. Each trial contributed to at least one meta-analysis. Trials involved children and adolescents with long-term physical conditions, such as chronic headache (migraine, tension headache, and others), chronic pain conditions (abdominal, musculoskeletal, and others), chronic respiratory illness (asthma, cystic fibrosis, and others), and symptoms of anxiety or depression. Participants were recruited from community settings and hospital clinics in high income countries.For the primary outcome of change in depression symptoms versus any control, there was very low-quality evidence meaning that it could not be determined whether e-health interventions were clearly better than any comparator (SMD -0.06, 95% CI -0.35 to 0.23; five RCTs, 441 participants). For the primary outcome of change in anxiety symptoms versus any comparator, there was very low-quality evidence meaning that it could not be determined whether e-health interventions were clearly better than any comparator (SMD -0.07, 95% CI -0.29 to 0.14; two RCTs, 324 participants). For the primary outcome of treatment acceptability, there was very low-quality evidence that e-health interventions were less acceptable than any comparator (SMD 0.46, 95% CI 0.23 to 0.69; two RCTs, 304 participants).For the secondary outcome of quality of life, there was very low-quality evidence meaning that it could not be determined whether e-health interventions were clearly better than any comparator (SMD -0.83, 95% CI -1.53 to -0.12; one RCT, 34 participants). For the secondary outcome of functioning, there was very low-quality evidence meaning that it could not be determined whether e-health interventions were clearly better than any comparator (SMD -0.08, 95% CI -0.33 to 0.18; three RCTs, 368 participants). For the secondary outcome of status of long-term physical condition, there was very low-quality evidence meaning that it could not be determined whether e-health interventions were clearly better than any comparator (SMD 0.06, 95% CI -0.12 to 0.24; five RCTs, 463 participants).The risk of selection bias was considered low in most trials. However, the risk of bias due to inadequate blinding of participants or outcome assessors was considered unclear or high in all trials. Only one study had a published protocol; two trials had incomplete outcome data. All trials were conducted by the intervention developers, introducing another possible bias. No adverse effects were reported by any authors. AUTHORS' CONCLUSIONS At present, the field of e-health interventions for the treatment of anxiety or depression in children and adolescents with long-term physical conditions is limited to five low quality trials. The very low-quality of the evidence means the effects of e-health interventions are uncertain at this time, especially in children aged under 10 years.Although it is too early to recommend e-health interventions for this clinical population, given their growing number, and the global improvement in access to technology, there appears to be room for the development and evaluation of acceptable and effective technologically-based treatments to suit children and adolescents with long-term physical conditions.

Abstract
BACKGROUND Acute infections with Mycoplasma pneumoniae (Mp) have been associated with worsening asthma in children. Mp can be present in the respiratory tract for extended periods; it is unknown whether the long-term persistence of Mp in the respiratory tract affects long-term asthma control. OBJECTIVE To determine the effect of Mp on asthma control. METHODS We enrolled 31 pediatric subjects 3 to 10 years of age with persistent asthma who completed up to 8 visits over a 24-month period. We detected Mp by antigen capture and polymerase chain reaction. Primary outcome measurements included symptom scores, quality of life, medication scores, oral corticosteroid use, health care usage, school absences, and exhaled breath condensate pH. RESULTS Low levels of Mp community-acquired respiratory distress syndrome toxin were detected in 20 subjects (64.5%) at enrollment. Subjects with Mp positivity at a given visit had a .579 probability of remaining Mp positive at the subsequent visit, whereas those with Mp negativity had a .348 probability of becoming Mp positive at the following visit. The incidence of Mp overall was higher in the spring and summer months. Overall, we found no significant relation between the detection of Mp and worse outcome measurements at the same visit or at subsequent visits. CONCLUSION The long-term persistence of Mp in the respiratory tract is common in children with asthma. However, the detection of Mp was not associated significantly with worse asthma symptoms, quality of life, health care usage, school absences, or exhaled breath condensate pH in this pediatric asthma cohort.

Abstract
OBJECTIVES The objective of the study was to determine whether parents who use a low-literacy, pictogram- and photograph-based written asthma action plan (WAAP) have a better understanding of child asthma management compared to parents using a standard plan. METHODS A randomized controlled study was carried out in 2 urban pediatric outpatient clinics. Inclusion criteria were English- and Spanish-speaking parents of 2- to 12-year-old asthmatic children. Parents were randomized to receive a low-literacy or standard asthma action plan (American Academy of Allergy, Asthma and Immunology) for a hypothetical patient on controller and rescue medications. A structured questionnaire was used to assess whether there was an error in knowledge of (1) medications to give everyday and when sick, (2) need for spacer use, and (3) appropriate emergency response to give albuterol and seek medical help. Multiple logistic regression analyses were performed, adjusting for parent age, health literacy (Newest Vital Sign); child asthma severity, medications; and site. RESULTS 217 parents were randomized (109 intervention and 108 control). Parents who received the low-literacy plan were (1) less likely to make an error in knowledge of medications to take everyday and when sick compared to parents who received the standard plan (63.0 vs. 77.3%, p = 0.03; adjusted odds ratio [AOR] = 0.5[95% confidence interval: 0.2-0.9]) and (2) less likely to make an error regarding spacer use (14.0 vs. 51.1%, p < 0.001; AOR = 0.1 [0.06-0.3]). No difference in error in appropriate emergency response was seen (43.1 vs. 48.1%, p = 0.5). CONCLUSIONS Use of a low-literacy WAAP was associated with better parent understanding of asthma management. Further study is needed to assess whether the use of this action plan improves child asthma outcomes.

Abstract
OBJECTIVE Resistive load detection tasks enable analysis of individual differences in psychophysical outcomes. The purpose of this study was to determine both the reliability and predictors of resistive load detection in children with persistent asthma who completed multiple testing sessions. METHODS Both University of North Carolina (UNC) Charlotte and Ohio University institutional review boards approved the research protocol. The detection of inspiratory resistive loads was evaluated in 75 children with asthma between 8 and 15 years of age. Each child participated in four experimental sessions that occurred approximately once every 2 weeks. Multivariate analyses were used to delineate predictors of task performance. RESULTS Reliability of resistive load detection was determined for each child, and predictors of load detection outcomes were investigated in two groups of children: those who performed reliably in all four sessions (n = 31) and those who performed reliably in three or fewer sessions (n = 44). Three factors (development, symptoms, and compliance) accounted for 66.3% of the variance among variables that predicted 38.7% of the variance in load detection outcomes (Multiple R = 0.62, p = 0.004) and correctly classified performance as reliable or less reliable in 80.6% of the children, χ(2)(12) = 28.88, p = 0.004. CONCLUSIONS Cognitive and physical development, appraisal of symptom experiences, and adherence-related behaviors (1) account for a significant proportion of the interrelationships among variables that affect perception of airflow obstruction in children with asthma and (2) differentiate between children who perform more or less reliably in a resistive load detection task.

Abstract
The goal of asthma treatment is to control the disease according to guidelines issued by bodies such as the Global Initiative for Asthma. Effective control is dependent upon evaluation of symptoms, initiation of appropriate treatment and minimization of the progressive adverse effects of the disease and its therapies. Although individual outcome measures have been shown to correlate with asthma control, composite endpoints are preferred to enable more accurate and robust monitoring of the health of the individual patient. A number of validated instruments are utilized to capture these component endpoints; however, there is no consensus on the optimal instrument for use in clinical trials. The Asthma Control Questionnaire (ACQ) has been shown to be a valid, reliable instrument that allows accurate and reproducible assessment of asthma control that compares favourably with other commonly used instruments. This analysis provides a summary of the use of ACQ in phase II, III and IV asthma trials. Comparisons between the ACQ and other instruments are also presented. Our analysis suggests that the ACQ is a valid and robust measure for use as a primary or secondary endpoint in future clinical trials.

Abstract
Patient-based measures for asthma control are important in assessing the worldwide impact of this highly prevalent chronic illness. We sought to refine an asthma symptom scale that RAND had previously developed to shorten it and validate it further, as well as reflect updated international expert definitions of asthma control. We conducted rigorous psychometric testing of new and adapted self-administered survey items in a sample of 2032 adults with asthma. The reliability and preliminary validity of the resulting measure, henceforth referred to as the RAND Asthma Control Measure (RAND-ACM), matched or exceeded that of the original RAND measure and others in the literature. RAND-ACM scores for worse asthma control were significantly associated with worse asthma-related quality of life, increased asthma-related healthcare use, Hispanic ethnicity and lower educational level. Evidence for internal consistency was strong with a Cronbach's α of 0.84. We also found adequate concordance between the RAND-ACM and the Global Initiative for Asthma categories of "uncontrolled", "partly controlled" and "controlled" asthma. The RAND-ACM, a five-item self-reported asthma control survey measure, performs well in a large ethnically-diverse sample of US adults with asthma and provides a cost-free alternative to other asthma control measures currently available.

Abstract
PURPOSE A key goal in asthma treatment is improvement in quality of life (QoL), but existing measures often confound QoL with symptoms and functional impairment. The current study addresses these limitations and the need for valid patient-reported outcome measures by using state-of-the-art methods to develop an item bank assessing QoL in adults with asthma. This article describes the process for developing an initial item pool for field testing. METHODS Five focus group interviews were conducted with a total of 50 asthmatic adults. We used "pile sorting/binning" and "winnowing" methods to identify key QoL dimensions and develop a pool of items based on statements made in the focus group interviews. We then conducted a literature review and consulted with an expert panel to ensure that no key concepts were omitted. Finally, we conducted individual cognitive interviews to ensure that items were well understood and inform final item refinement. RESULTS Six hundred and sixty-one QoL statements were identified from focus group interview transcripts and subsequently used to generate a pool of 112 items in 16 different content areas. CONCLUSIONS Items covering a broad range of content were developed that can serve as a valid gauge of individuals' perceptions of the effects of asthma and its treatment on their lives. These items do not directly measure symptoms or functional impairment, yet they include a broader range of content than most existent measures of asthma-specific QoL.

Abstract
OBJECTIVE For patients with asthma, exacerbations and poor control can result from exposure to environmental triggers, such as allergens and air particulates. This study reviewed the international literature to determine whether a global checklist of common asthma triggers might be feasible for use as a research or management tool in clinical practice. METHODS Literature published from 2002 to 2012 was identified through PubMed and EMBASE using the following search terms: asthma, asthma triggers, prevalence, among others. A total of 1046 abstracts were found; 85 articles were reviewed covering six continents (number of articles): Africa (1), Asia (22), Australia (1), Europe (27), North America (22), and South America (4). RESULTS The literature consistently pointed to asthma triggers as one contributor to poor asthma control. Frequently cited triggers were similar across countries/regions and included allergens (particularly pollens, molds, dust, and pet dander), tobacco smoke, exercise, air pollutants/particulates, weather patterns/changes, and respiratory infections. Definitions of asthma triggers, how triggers are taken into account in definitions of asthma control, and scientific inquiry into optimal management techniques for triggers were inconsistent and sparse. CONCLUSIONS Given the apparent importance of triggers in attaining and maintaining asthma control, empirical research concerning optimal trigger management is needed. Results demonstrate that asthma triggers are similar across continents, suggesting a global checklist of triggers for use in research and clinical practice would be feasible.

Abstract
BACKGROUND AND OBJECTIVE Although children living in Puerto Rico have the highest asthma prevalence of all US children, little is known regarding the quality-of-care disparities they experience nor the adaptability of existing asthma evidence-based interventions to reduce these disparities. The objective of this study was to describe our experience in reducing quality-of-care disparities among Puerto Rican children with asthma by adapting 2 existing evidence-based asthma interventions. METHODS We describe our experience in adapting and implementing 2 previously tested asthma evidence-based interventions: the Yes We Can program and the Inner-City Asthma Study intervention. We assessed the feasibility of combining key components of the 2 interventions to reduce asthma symptoms and estimated the potential cost savings associated with reductions in asthma-related hospitalizations and emergency department visits. A total of 117 children with moderate and severe asthma participated in the 12-month intervention in 2 housing projects in San Juan, Puerto Rico. A community-academic team with the necessary technical and cultural competences adapted and implemented the intervention. RESULTS Our case study revealed the feasibility of implementing the combined intervention, henceforth referred to as La Red intervention, in the selected Puerto Rican communities experiencing a disproportionately high level of asthma burden. After 1-year follow-up, La Red intervention significantly reduced asthma symptoms and exceeded reductions of the original interventions. Asthma-related hospitalizations and emergency department use, and their associated high costs, were also significantly reduced. CONCLUSIONS Asthma evidence-based interventions can be adapted to improve quality of care for children with asthma in a different cultural community setting.

Abstract
OBJECTIVE To identify the predictive factors of early childhood wheezing in children of low socioeconomic status. STUDY DESIGN The Childhood Asthma Prevention Study enrolled 177 low-income children (9-24 months old) with frequent wheezing. At age 7 years, presence of asthma was assessed through caregiver reports of physician diagnosis of asthma (CRPDA) and corroborated by assessment of bronchial hyperresponsiveness (BHR). Lung function, inflammatory markers, and asthma symptom severity were compared for children with ±CRPDA, ±BHR, and asthma. Baseline predictors for CRPDA, BHR, and asthma at 7 years of age were examined. RESULTS Maternal symptom report strongly differentiated children with +CRPDA (49%) despite comparable airflow measurements (P < .0001), and spirometric lung function measurements were different for +BHR (65%) versus -BHR (P < .005). Univariate analyses revealed different baseline predictors of +CRPDA and +BHR for children at age 7 years. Higher levels of maternal psychological resources were associated with +CRPDA, but not +BHR. Only 39% of children with a history of frequent wheezing met the conservative definition of asthma at age 7 years, with the following significant predictors found: low birth weight, baseline symptom severity, and maternal psychological resources. CONCLUSIONS This low-income, multi-ethnic group of wheezing infants represents a unique population of children with distinct characteristics and risks for persistent asthma. Determination of asthma status at 7 years of age required objective measurement of BHR in addition to CRPDA. The association of maternal psychological resources with +CRPDA may represent a previously unrecognized factor in the determination of asthma status among low-income groups.

Abstract
BACKGROUND National Institutes of Health asthma guidelines recommend questionnaires to assess asthma control, but these questionnaires are not useable across the entire pediatric age spectrum and have not been validated among significant numbers of minority or Spanish-speaking children. OBJECTIVE We sought to evaluate a questionnaire designed to assess asthma control across a broad age range of minority and Spanish-speaking children cared for in an outpatient setting. METHODS Between July 1, 2007, and September 30, 2010, we collected information using the Pediatric Asthma Control and Communication Instrument (PACCI), the Asthma Control Test (ACT; or the childhood ACT for children 4-11 years old), the Pediatric Asthma Caregiver Quality of Life Questionnaire, and lung function and clinicians' ratings of asthma status among a population of children presenting for routine asthma specialist care. The PACCI measure of asthma control was validated by evaluating accuracy, internal reliability, and concurrent, discriminative, and known-groups validity. RESULTS We collected information on 265 English- and 52 Spanish-speaking children (mean age, 8.2 years; 58% male; 44% African American). Across all age groups and in both languages, PACCI control showed good internal reliability and strong concurrent, discriminative, and known-groups validity with ACT and Pediatric Asthma Caregiver Quality of Life Questionnaire scores and clinicians' ratings of asthma control. The accuracy of the PACCI in classifying children with uncontrolled asthma was good (area under the curve, 0.83; 95% CI, 0.79-0.88). CONCLUSIONS The PACCI accurately measures asthma control in English- and Spanish-speaking children. The PACCI should be useful to clinicians to assess and classify asthma according to National Institutes of Health asthma guidelines.

Abstract
BACKGROUND Current asthma guidelines recommend assessing the level of a patient's asthma control. Consequently, there is increasing use of asthma control as an outcome measure in clinical research studies. Several composite assessment instruments have been developed to measure asthma control. OBJECTIVE National Institutes of Health institutes and federal agencies convened an expert group to propose the most appropriate standardized composite score of asthma control instruments to be used in future asthma studies. METHODS We conducted a comprehensive search of PubMed using both the National Library of Medicine's Medical Subject Headings and key terms to identify studies that attempted to develop and/or test composite score instruments for asthma control. We classified instruments as core (required in future studies), supplemental (used according to study aims and standardized), or emerging (requiring validation and standardization). This work was discussed at a National Institutes of Health-organized workshop convened in March 2010 and finalized in September 2011. RESULTS We identified 17 composite score instruments with published validation information; all had comparable content. Eight instruments demonstrated responsiveness over time; 3 demonstrated responsiveness to treatment. A minimal clinically important difference has been established for 3 instruments. The instruments have demographic limitations; some are proprietary, and their use could be limited by cost. CONCLUSION Two asthma composite score instruments are sufficiently validated for use in adult populations, but additional research is necessary to validate their use in nonwhite populations. Gaps also exist in validating instruments for pediatric populations.

Abstract
OBJECTIVES Asthma affects 25-30% of children living in certain disadvantaged Chicago neighborhoods, a rate twice the national prevalence (13%). Children living in poor, minority communities tend to rely heavily on the emergency department (ED) for asthma care and are unlikely to be properly medicated or educated on asthma self-management. A pilot project implemented and evaluated a community health worker (CHW) model for its effectiveness in reducing asthma morbidity and improving the quality of life among African-American children living in disadvantaged Chicago neighborhoods. METHODS Trained CHWs from targeted communities provided individualized asthma education during three to four home visits over 6 months. The CHWs also served as liaisons between families and the medical system. Seventy children were enrolled into the pilot phase between 15 November 2004 and 15 July 2005, of which 96% were insured by Medicaid and 54% lived with a smoker. Prior to starting, the study was approved by an institutional review board. Data on 50 children (71.4%) who completed the entire 12-month evaluation phase were analyzed using a before and after study design. RESULTS Findings indicate improved asthma control. Specifically, symptom frequency was reduced by 35% and urgent health resource utilization by 75% between the pre- and post-intervention periods. Parental quality of life also improved by a level that was both clinically and statistically significant. Other important outcomes included improved asthma-related knowledge, decreased exposure to asthma triggers, and improved medical management. The intervention was also shown to be cost-effective, resulting in an estimated $5.58 saved per dollar spent on the intervention. CONCLUSIONS Findings suggest that individualized asthma education provided by a trained, culturally competent CHW is effective in improving asthma management among poorly controlled, inner-city children. Further studies are needed to affirm the findings and assess the model's generalizability.

Abstract
OBJECTIVE The objectives of this study were to: 1) examine the psychometric properties of three shortened versions of the Asthma Control Questionnaire (ACQ) and their comparative performance with the original 7-item ACQ in persistent asthma patients; and 2) explore the concordance of asthma control outcomes from the four versions of the ACQ when compared with international guidelines for asthma control. METHOD Post-hoc analyses of two large (n=737 and n=772) Phase III, randomized, double-blind, parallel-group, multi-center placebo-controlled studies of mometasone furoate/formoterol fumarate combination formulation compared with monotherapies in subjects with persistent asthma previously treated with low-dose or medium-dose inhaled glucocorticoids. This study examined the psychometric performance of the four ACQ versions and the concordance between these four versions with each other and international guidelines. RESULTS The psychometric results for all four versions of the ACQ were robust, with Cronbach alphas ≥0.82 and test-retest ICCs ≥0.75. All versions of the ACQ were strongly correlated with each other (r≥0.97), as well the overall score from the AQLQ12+ for both baseline and change scores (|r|≥0.74). When the four ACQ versions were compared to each other, both cross sectional and longitudinal change concordances were mostly substantial, but agreements were lower when compared to international guidelines classifications. CONCLUSION All ACQ versions have similar and strong psychometric properties. Classifications of change over time using the original ACQ and a six-item version without SABA use provided generally fair to moderate agreement with the international guidelines criteria for asthma control.

Abstract
BACKGROUND Asthma, a leading chronic disease of children, currently affects about 6.2 million (8.5%) children in the United States. Despite advances in asthma research and availability of increasingly effective therapy, many children do not receive appropriate medications to control the disease, have over-reliance on reliever medication, and lack systematic follow-up care. The situation is even worse for poor inner-city and minority children who have significantly worse asthma rates, severity, and outcomes. National Asthma Education and Prevention Program Guidelines recommend a multimodal, chronic care approach. OBJECTIVE The authors assessed the effectiveness of practice redesign and computerized provider feedback in improving both practitioner adherence to National Asthma Education and Prevention Program Guidelines (NAEPP), and patient outcomes in 295 poor minority children across four Federally Qualified Health Centers (FQHC). METHODS In a nonrandomized, two-group (intervention versus comparison), two-phase trial, all sites were provided redesign support to provide quarterly well-asthma visits using structured visit forms, community health workers for outreach and follow-up, a Web-based disease registry for tracking and scheduling, and a provider education package. Intervention sites were given an additional Web-based, computerized patient-specific provider feedback system that produced a guideline-driven medication assessment prompt. RESULTS Logistic regression results showed that providers at intervention sites were more than twice as likely on average to prescribe guideline-appropriate medications after exposure to our feedback system during the Phase I enrollment period than providers at comparison sites (exp(B) = 2.351, confidence interval [CI] = 1.315-4.204). In Phase II (the post-enrollment visit period), hierarchical linear models (HLMs) and latent growth curves were used to show that asthma control improved significantly by .19 (SE = .05) on average for each of the remaining four visits (about 11% of a standard deviation), and improved even more for patients at intervention sites. These results show that implementation of practice redesign support guided by a pediatric chronic care model can improve provider adherence to treatment guidelines as well as patients' asthma control. CONCLUSIONS The addition of patient-specific feedback for providers results in quicker adoption of guideline recommendations and potentially greater improvements in asthma control compared to the basic practice redesign support alone.

Abstract
BACKGROUND This cross-sectional study examines parents' perceptions of their neighborhoods and general and respiratory health among low-income Chicago families. Asthma disproportionately affects nonwhite, urban, and low socioeconomic status (SES) populations, but Chicago's burden, and the national epidemic, are not well explained by known risk factors. Urban dwellers experience acute and chronic stressors that produce psychological distress and are hypothesized to impact health through biological and behavioral pathways. Identifying factors that covary with lower SES and minority-group status-e.g., stress-is important for understanding asthma's social patterning. METHODS We used survey data from 319 parents of children 5-13 years with asthma/respiratory problems and principal components analysis to create exposure variables representing parents' perceptions of two aspects of neighborhoods: collective efficacy ("CE") and physical/social order ("order"). Adjusted binomial regression models estimated risk differences (RDs) and 95% confidence intervals (CIs) for eight binary outcomes. RESULTS Magnitude was generally as expected, i.e., RD for low- versus high- (most favorable) exposure groups (RD(low v. high)) was larger than for the middle versus high contrast (RD(mid v. high)). "Parent general health" was strongly associated with "CE" (RD(low v. high) = 20.8 [95% CI: 7.8, 33.9]) and "order" (RD(mid v. high) = 11.4 [95% CI: 2.1, 20.7]), unlike "child general health," which had nearly null associations. Among respiratory outcomes, only "waking at night" was strongly associated with "CE" (RD(low v. high) = 16.7 [95% CI: 2.8, 30.6]) and "order" (RD(low v. high) = 22.2 [95% CI: 8.6, 35.8]). "Exercise intolerance" (RD(low v. high) = 15.8 [95% CI: 2.1, 29.5]) and "controllability" (RD(mid v. high) = 12.0 [95% CI: 1.8, 22.3]) were moderately associated with "order" but not with "CE," whereas "school absences," "rescue medication use," and "unplanned visits" had nearly null associations with both exposures. CONCLUSIONS More negative perceptions tended to be associated with higher risk of undesirable outcomes, adding to evidence that the social environment contributes to health and supporting research on stress' health impact among disadvantaged populations. Interventions must address not only traditional "environmental" factors, but also individuals' reactions to stress and attempt to mitigate effects of stressors while structural solutions to health inequities are sought.

Abstract
Asthma control is recognized as a critical aspect of the evaluation and management of the disease. Here we evaluate and compare existing instruments for measuring asthma control in an attempt to evaluate their clinical utility. Based on a literature review, we identified validated instruments used to assess asthma control in adults. We examined the specific measurement properties and the strengths and weaknesses of each instrument, and evaluated a single instrument, the Asthma Control Questionnaire (ACQ), more closely as an example, evaluating its applicability in the clinical setting. Our review identified five validated instruments designed to measure asthma control: the Asthma Control Questionnaire (ACQ), Asthma Control Scoring System (ACSS), Asthma Control Test (ACT), Asthma Therapy Assessment Questionnaire (ATAQ), and the Lara Asthma Symptom Scale (LASS). None of the instruments covered all relevant control characteristics, but most were aligned with guideline definitions of control. All instruments demonstrated validity and responsiveness, with some measure of reliability. All instruments were short and easily administered, easy to interpret, and all had evidence to support their use in clinical decision making.

Abstract
BACKGROUND Depression is common in caregivers of children with asthma and is associated with increased emergency service utilization for the child's asthma. OBJECTIVE This pilot study examined the impact of antidepressant treatment of depressed caregivers on the caregiver's depression and the child's asthma. METHOD Eight depressed caregivers of children with asthma were given up to 6 months of algorithm-based antidepressant therapy. RESULTS Caregiver depressive symptoms and the child's asthma symptoms improved significantly. CONCLUSION Unscheduled clinic visits showed a trend toward significant decrease. Larger trials are needed to confirm these findings and identify mechanisms linking improvement in caregiver depression with improvement in their child's asthma.

Abstract
BACKGROUND The goal of disease management (DM) is to improve health outcomes and reduce cost through decreasing health care utilization. Although some studies have shown that DM improves asthma outcomes, these interventions have not been examined in a large randomized controlled trial. OBJECTIVE To compare the effectiveness of 2 previously successful DM programs with that of traditional care. METHODS Nine hundred two individuals with asthma (429 adults; 473 children) were randomly assigned to telephonic DM, augmented DM (ADM; DM plus in-home visits by a respiratory therapist), or traditional care. Data were collected at enrollment and at 6 and 12 months. Primary outcomes were time to first asthma-related event, quality of life (QOL), and rates of asthma-related health care utilization. Secondary outcomes included rate of controller medication initiation, number of oral corticosteroid bursts, asthma symptom scores, and number of school days missed. RESULTS There were no significant differences between groups in time to first asthma-related event or health care utilization. Adult participants in the ADM group had greater improvement in QOL (P = .04) and a decrease in asthma symptoms (P = .001) compared with other groups. Of children not receiving controller medications at enrollment (13%), those in the intervention groups were more likely to have controller medications initiated than the control group (P = .01). Otherwise, there were no differences in outcomes. CONCLUSIONS Overall, participation in asthma DM did not result in significant differences in utilization or clinical outcomes. The only significant impact was a higher rate of controllermedication initiation in children and improvement in asthma symptoms and QOL in adults who received ADM.

Abstract
BACKGROUND Accurate assessment of asthma symptoms is critical in research and clinical settings. A multidimensional asthma control questionnaire could provide more accurate information about asthma symptoms than global assessments, which often overestimate asthma control. OBJECTIVE We sought to evaluate the efficacy of the Lara Asthma Symptom Scale (LASS) in adults with persistent asthma. METHODS Participants were 18 to 64 years of age with persistent asthma. Data were collected at baseline, 6 months, and 12 months. We described the construct and predictive validity of the LASS by comparing it with measures of pulmonary function (FEV(1)), asthma-specific quality of life (Juniper's Asthma Quality of Life Questionnaire [AQLQ]), and health care use (emergency department [ED] visits and hospitalizations). RESULTS Three hundred eighty-three participants provided baseline data. The LASS had high internal consistency reliability (Cronbach alpha = .84). LASS scores correlated significantly with baseline measures of FEV(1) (-0.20, P = .0002), AQLQ (-0.68, P < .0001), ED visits (0.17, P = .002), and hospitalizations (0.15, P = .008). Baseline LASS scores were associated significantly with ED visits (P = .03) and hospitalizations (P = .04) over the subsequent 12 months. Change in LASS scores over time correlated significantly with changes in FEV(1) (-0.22, P = .001) and AQLQ (-0.70, P < .001). CONCLUSIONS The LASS demonstrated good internal consistency, excellent validity based on concurrent criterion validity and longitudinal predictive validity, and good discriminatory properties in a heterogeneous sample of adults with persistent asthma. CLINICAL IMPLICATIONS This study validates a simple multidimensional asthma questionnaire as a clinical tool in the assessment of asthma control in adults.

Abstract
We explore the relationship between home-based triggers, asthma symptoms, and quality of life (QOL) with data from 177 adult and pediatric participants who received a home environmental assessment. Outcomes included the Asthma Quality of life Questionnaire, the Prediatric Asthma Quality of Life Questionnaire, the Paediatric Asthma Caregiver's Quality of Questionnaires and the Lara Asthma Symptom Scale. The absence of roaches and the use of dust mite covers were positively associated with QOL in pediatric and adult participants. Frequent bed sheet washing was associated with increased symptoms and decreased quality of life in adults and caregivers of pediatric participants. These findings confirm existing wisdom on roaches and dust mite covers and raise important questions about bed sheet washing recommendations.

Abstract
BACKGROUND For children younger than 12 years old with asthma, there are several quality-of-life instruments, clinical diaries, and questionnaires assessing symptoms; however, a validated tool for assessing asthma control is currently lacking. OBJECTIVE To develop and validate the Childhood Asthma Control Test (C-ACT), a self-administered tool for identifying children aged 4-11 years whose asthma is inadequately controlled. METHODS A 21-item questionnaire was administered to 343 patients with asthma and their caregivers, randomly assigning 75% (n = 257) for development and cross-sectional validation of the tool and 25% (n = 86) to a confirmatory sample. Stepwise logistic regression was used to reduce the 21 items to those best able to discriminate control as defined by the specialist's rating of asthma control. RESULTS Seven items were selected from regression analyses of the development sample to comprise the C-ACT. The scores of each item were summed for a total score (0-27), with lower scores indicating poorer control. Summed scores discriminated between groups of patients differing in the specialists' rating of asthma control (F = 36.89; P < .0001), the need for change in patients' therapy (F = 20.07; P < .0001), and % predicted FEV(1) (F = 2.66; P = .0494). A score of 19 indicated inadequately controlled asthma (specificity 74%, sensitivity 68%). These analyses were confirmed in the confirmatory sample. CONCLUSION The C-ACT is a validated tool to assess asthma control and identify children with inadequately controlled asthma. CLINICAL IMPLICATIONS The C-ACT can be valuable in clinical practice and research based on its validation, ease of use, input from the child and caregiver, and alignment with asthma guidelines.

Abstract
The authors report on the development and evaluation of a novel patient-centered technology that promotes capture of critical information necessary to drive guideline-based care for pediatric asthma. The design of this application, the asthma kiosk, addresses five critical issues for patient-centered technology that promotes guideline-based care: (1) a front-end mechanism for patient-driven data capture, (2) neutrality regarding patients' medical expertise and technical backgrounds, (3) granular capture of medication data directly from the patient, (4) formal algorithms linking patient-level semantics and asthma guidelines, and (5) output to both patients and clinical providers regarding best practice. The formative evaluation of the asthma kiosk demonstrates its ability to capture patient-specific data during real-time care in the emergency department (ED) with a mean completion time of 11 minutes. The asthma kiosk successfully links parents' data to guideline recommendations and identifies data critical to health improvements for asthmatic children that otherwise remains undocumented during ED-based care.

Abstract
OBJECTIVE Accurately measuring the health of the increasingly diverse population of US children requires instruments that are comparable and valid across cultures, economic background, and language. This paper asks: Has the field of pediatric health status measures reached this level of comprehensiveness? METHODS Children's health status and quality of life measures commonly used in the United States were reviewed to assess how they have included racial/ethnic minority and low-income groups. Four generic and 2 condition-specific instruments (asthma) were examined for total sample size, percent of sample from racial/ethnic and low-income groups, language availability, translation methods for US-Spanish, reading level, and separately reported psychometric findings and outcomes/scores. RESULTS Most measures have included minority groups, usually African American or Hispanic children, although with little information by Hispanic subgroup. Children's measures have generally been tested on relatively small samples, without separate analyses by subgroups. When done, tests of reliability and validity find few differences from the general population. Some studies report information on health by racial or ethnic group, but the findings are inconclusive. Economic status is usually measured in some way, but rarely are psychometric findings examined separately by income. When differences in health outcome are reported by income, lower income children usually have poorer health. CONCLUSIONS Much has been accomplished in advancing health status measures for children. Next-generation issues include the influence of race, ethnicity, and income on health and health reports.

Abstract
OBJECTIVES To assess the structural, convergent, discriminant, and criterion validity of the Spanish version of the Child Health and Illness Profile-Adolescent Edition (CHIP-AE) and to compare results with the U.S. version. SUBJECTS A sample of adolescents aged 12 to 19 attending schools and representative of the school-aged population in Barcelona, Spain (n = 902). MEASURES Exploratory factor analyses were performed, and results compared with the U.S. version. The Child Depression Inventory (CDI) and the State-Trait Anxiety Inventory (STAIC) were administered to a subgroup of adolescents to assess convergent and discriminant validity. Criterion validity was assessed by using receiver operating characteristic (ROC) curves to examine the ability of the CHIP-AE academic performance subdomain to predict school grades. RESULTS The Spanish version has 6 defined domains with a factor structure showing minor differences from the U.S. version. Higher correlations were found between the CDI and STAIC and CHIP-AE subdomains of emotional discomfort and self-esteem (range. 0.48-0.80, P<0.01) than with scales measuring dissimilar concepts. The area under the ROC curve was 0.83 (95% confidence interval, 0.75-0.92) for the number of failed subjects (none/one or more) related to academic performance. CONCLUSIONS The underlying theoretical model of the Spanish version of the CHIP-AE functions well in Spain, and the Spanish version has acceptable levels of convergent, discriminant, and criterion validity. Sensitivity to change and the use of the health profiles need to be assessed.

Abstract
AIM The Child Health and Illness Profile (CHIP-AE) is a generic health status instrument for adolescents aged 12-19 years adapted for use in Spain. The aim of this study was to obtain reference population values of the Spanish version of the CHIP-AE. METHODS The CHIP-AE was administered to a representative sample of adolescents from schools in Barcelona. The sample was selected by using cluster-sampling, stratified by type of school (public or private) and an ecological socioeconomic index (Indice de Capacidad Familiar: low, middle, and high). The CHIP-AE scores were standardized to a mean of 20 and a standard deviation (SD) of 5. Means and percentiles were computed. Means were compared by age, gender, and socioeconomic status using analysis of variance. RESULTS The response rate was 81% (n = 902). The distribution of the CHIP-AE scores presented a wide range with scores generally skewed toward positive health status. Nevertheless, the results suggest that the sample selected from a general population was not free of health problems. Twenty-five percent of adolescents presented scores below 17.2 in the domain of discomfort, indicating an effect size of 0.56 standardized SD units. The distribution of scores in the reference samples from Barcelona was similar to the original results in Baltimore (USA), with some marginal differences in individual risks. CONCLUSIONS The CHIP-AE systematically gathers information on health domains in adolescents. The results from this reference sample will allow comparisons with adolescents from other regions, and/or with different health problems, as well as description of inequalities in health during adolescence.

Abstract
Our objective was to explore, in a predominantly Latino inner-city population, why caregivers bring their children with asthma to the ED (emergency department). We conducted bilingual parent surveys and medical chart abstractions of a consecutive ED sample consisting of 234 children with asthma (69% Latino; 54% Spanish-speaking) and their caregivers. Outcome measures included: (1) the acute need for ED services based on objective physiological measures, (2) the extent to which these children experienced barriers to quality primary care for asthma before the ED visit, and (3) the relative importance caregivers assigned to worsening symptoms versus perceived barriers to non-ED care when deciding to bring their child to the ED. Most children had moderate or severe asthma attacks. In the prior month, only 33% went to a primary care provider, 83% had used a bronchodilator, and 63%, an age-appropriate spacer device. Seventy-five percent of caregivers cited perceived acute need, instead of barriers to primary care, as the most important reason for using the ED. This perception of acute need was associated with moderate or severe asthma attacks according to objective physiological measures, after controlling for health and sociodemographic characteristics. Children with asthma who use the ED encounter barriers to primary care, but caregivers' perception of acute need--validated by independent measures of attack severity--dominates caregivers' decision to use the ED. Ensuring continuity of care for children with asthma would involve not only improving various aspects of access to and quality of primary non-ED care--including parent education about early recognition and treatment of asthma attacks--but also providing families with practical low-cost alternatives for 24-hour care and assuring linkages between the ED and sources of primary care.

Abstract
BACKGROUND Because no validated "gold standard" for measuring asthma outcomes exists, asthma interventions are often evaluated using a large number of disease status measures. Some of these measures may be redundant, whereas others may be complementary. Use of multiple outcomes may lead to ambiguous results, increased type I error rates, and be an inefficient use of resources including caregiver and patient/participant time and effort. Understanding the relationship between these measures may facilitate more parsimonious and valid evaluation strategies without loss of information. OBJECTIVE To assess the relationships between multiple measures of asthma disease status over time. DESIGN/METHODS We used data from a randomized, controlled trial of a comprehensive disease management program involving 119 disadvantaged inner-city children aged 5 to 12 years with moderate to severe asthma. Spearman correlations were calculated between the following asthma disease status measures: parent-reported disease symptoms, parent-reported health care utilization, functional health status using the American Academy of Pediatrics' validated Child Health Survey for Asthma (CHSA), diary data (symptom scores, night wakings, and bronchodilator use), and pulmonary function tests at baseline, 32 weeks, 52 weeks, and changes from baseline to 52 weeks. RESULTS Ninety-four (79%) of randomized patients participated at baseline and 52 weeks. Completion rates for outcome measures ranged from 79% (CHSA, spirometry data) to 64% (diary data). At baseline, asthma symptoms, health care utilization, and individual domains from the CHSA were significantly correlated (r = 0.21-0.53). These correlations were stable over the 52-week follow-up. Forced expiratory volume in 1 second and diary data did not correlate to any other measures at baseline, and these measures correlated only inconsistently with other measures at 32 weeks and 52 weeks. Baseline to 52-week changes in asthma symptoms, utilization, and the CHSA domains were significantly correlated (0.22-0.56), as were baseline to 52-week changes in symptom days, night wakings, and the CHSA domains (r = 0.24-0.64). Baseline to 52-week changes in forced expiratory volume in 1 second and diary data did not correlate with other measures. CONCLUSIONS These results suggest that asthma status and change in asthma status over time after introduction of a disease management intervention are best characterized by parent-reported symptoms, parent-reported utilization, and functional health status measures. Asthma diaries and pulmonary function tests did not seem to provide additional benefit, although they may play an important role in individual patient management. Our findings suggest a parsimonious evaluation strategy would include collection of key data elements regarding symptoms, utilization, and functional health status only, without loss of vital response information.

Abstract
OBJECTIVE Racial/ethnic disparities in hospitalization rates among children with asthma have been documented but are not well-understood. Medicaid programs, which serve many minority children, have markedly increased their use of managed care in recent years. It is unknown whether racial/ethnic disparities in health care use or other processes of care exist in managed Medicaid populations. This study of Medicaid-insured children with asthma in 5 managed care organizations aimed to 1) compare parent-reported health status and asthma care processes among black, Latino, and white children and 2) test the hypothesis that racial/ethnic variations in processes of asthma care exist after adjusting for socioeconomic status and asthma status. METHODS This cross-sectional study collected data via telephone interviews with parents and computerized records for Medicaid-insured children with asthma in 5 managed care organizations in California, Washington, and Massachusetts. The American Academy of Pediatrics (AAP) Children's Health Survey for Asthma was used to measure parent-reported asthma status. We used multivariate models to evaluate associations between race/ethnicity and asthma status while controlling for other sociodemographic variables. We evaluated racial/ethnic variations in selected processes of asthma care while controlling for other demographic variables and asthma status. RESULTS The response rate was 63%. Of the 1658 children in the respondent group, 38% were black, 19% were Latino, and 31% were white. Black children had worse asthma status than white children on the basis of the AAP asthma physical and emotional health scores, symptom-days, and school days missed in the past 2 weeks. Latino children had equivalent AAP scores but missed more school days than white children. On the basis of the AAP asthma physical health score, the black-white disparity persisted after adjusting for other sociodemographic variables. After adjusting for sociodemographic variables and asthma status, black and Latino children were less likely to be using inhaled antiinflammatory medication than white children (relative risk for blacks: 0.69; relative risk for Latinos: 0.58). They were more likely to have home nebulizers. Other processes of asthma care, including ratings of providers and asthma care, use of written management plans, use of preventive visits and specialists, and having no pets or smokers at home, were equal or better for minority children compared with white children. CONCLUSIONS Black and Latino children had worse asthma status and less use of preventive asthma medications than white children within the same managed Medicaid populations. Most other processes of asthma care seemed to be equal or better for minorities in the populations that we studied. Increasing the use of preventive medications is a natural focus for reducing racial disparities in asthma.

Abstract
Accurate assessment of the value of asthma interventions in pediatric clinical trials is an essential step toward the improvement of the treatment of this disorder in children. Conventional pulmonary function measures can be infeasible and unreliable in younger children, particularly for use in multisite studies. As an alternative or supplemental approach, diary questionnaires completed by the patients or their caregivers may provide valuable data regarding the efficacy of asthma interventions in pediatric clinical trials. These questionnaires, however, have routinely not been validated for use in pediatric populations. Two pediatric diary questionnaires (the child-completed Pediatric Asthma Diary [PAD] and the parent/caregiver-completed Pediatric Asthma Caregiver Diary [PACD]) were designed to evaluate asthma symptoms in children aged 6 to 14 years and 2 to 5 years, respectively. The validity of these diary questionnaires was evaluated in 2 separate prospective studies that included children who were divided into 2 asthma groups: stable (requiring no additional asthma medication) and unstable (requiring either an increase in or the addition of asthma medication). Both scales displayed significant discriminant validity, construct validity, and responsiveness to change in asthma therapy. Only the PACD detected differences between groups in nighttime symptoms, such as awakenings caused by asthma. These validity studies suggest that diary questionnaires such as the PAD and PACD can be valuable as an alternative for the evaluation of interventions in pediatric asthma when pulmonary function testing is inappropriate or as an adjunct to such objective measures.
