Family emotional climate, depression, emotional triggering of asthma, and disease severity in pediatric asthma: examination of pathways of effect.

OBJECTIVES: (a) To assess emotional triggering of pediatric asthma and ascertain its contribution to disease morbidity and functional status; (b) to test whether negative family emotional climate (NFEQ) is associated with depressive and/or anxious symptoms and emotional triggering of asthma attacks in the child. METHOD: Children with asthma (N = 272, 56% male, age 7-17) and their primary caregivers answered together an Asthma Trigger Inventory (Ritz, Steptoe, Bobb, Harris, & Edwards, 2006). Children reported on anxious (STAIC) and depressive (CDI) symptoms and on asthma-related quality of life (PAQLQ). Parent(s) reported on their child's internalizing (CBCL-I) and depressive symptoms (CDI-P). A clinician also rated the child's depression using the structured CDRS-R. Asthma diagnosis was confirmed and disease severity rated according to NHLBI guidelines by an asthma clinician. RESULTS: Path analyses indicated that NFEQ was associated with depressive symptoms, which in turn were associated both directly and indirectly (by way of emotional triggering) with disease severity. Comparison of nested models indicated the possibility of differential roles and pathways for anxious versus depressive symptoms. CONCLUSION: Findings elucidate possible pathways of effect by which family emotional climate and child depressive symptoms may influence pediatric asthma disease severity by way of potentiating emotional triggering of asthma.

Cough variant asthma is associated with a higher wheezing threshold than classic asthma.

Cough variant asthma is an occult form of asthma in which the only sign or symptom is chronic cough. It is a common problem amongst all ages that frequently goes unrecognized, leading to underdiagnosis and undertreatment. To characterize the pathophysiological abnormalities in these patients, we performed bronchial provocation tests with methacholine using the stepwise doubling concentration technique, and measured the concentration of methacholine and the severity of airway obstruction when wheezing was first detected. Airway hyperresponsiveness, defined as PC20 in the cough variant asthma group was not significantly different from that of classic asthma. There was a good correlation between the PCW (the concentration of methacholine causing wheezing) and the PC20 with the PCW values higher than PC20 values in both groups. However, in the cough variant asthma group, the PCW:PC20 ratio was greater than that of the classic asthma group. Furthermore, the mean % fall in FEV1 at which wheezing was first detected in the former group was significantly larger than that of the latter group. The results indicated that the mechanism for the manifestation of cough without wheeze in the cough variant asthma may be a higher wheezing threshold, i.e. wheezing becomes audible at the greater degree of airway obstruction than classic asthma. They suggested that patients with cough variant asthma may represent a subset of asthmatic subjects whose airways are less able to produce a wheeze.

The associations between childhood asthma and atopy, and parental asthma, hay fever and smoking.

The aim of this analysis was to examine the degree to which a life time prevalence of asthma in a 7-year-old child is statistically associated with atopic conditions of the child, and with parental asthma, hay fever and smoking. In 1968, 8585 children who were born in 1961 and who were attending school in Tasmania were surveyed. This comprised 99% of the eligible population. The prevalence of a history of asthma in the 7-year-olds was 16.2% (males 19.0%, females 13.2%). Multiple logistic regression analysis showed that a history of asthma in a 7-year-old was associated with the child being male (odds ratio [OR] 1.56; 99% confidence interval 1.30-1.86), having a history of hay fever (3.86; 3.12-4.78), eczema (2.04; 1.63-2.55), hives (1.34; 1.09-1.65) or allergy to foods or medicines (1.70; 1.26-2.30), the child's mother or father having a history of asthma (2.63; 2.08-3.31 or 2.52; 1.99-3.19, respectively), and the mother being a smoker (1.26; 1.05-1.51). Parental hay fever and paternal smoking were not independently associated with childhood asthma. The strength of association between childhood asthma and parental asthma was independent of the sex of either the parent or the child, and of atopic conditions in the child. In the 133 children for whom both parents were asthmatic, 65 (49%) had a history of asthma.(ABSTRACT TRUNCATED AT 250 WORDS)

Prevalence of asthma and asthma symptoms in a general population sample from northern Italy. European Community Respiratory Health Survey--Italy.

The European Community Respiratory Health Survey is an international survey of the general population which aims to establish whether there are significant variations in the prevalence of asthma among European countries. The present paper reports the prevalence of asthma and asthma-like symptoms in a sample of subjects living in three areas of northern Italy: Turin, Pavia, and Verona. Samples of residents 20-44 years old (3000 subjects in Turin and Verona and 1000 in Pavia) stratified by sex (M:F = 1/1) were randomly selected from local health authority lists in the three participating areas. To correct the observed prevalence estimate for nonresponse bias, a method proposed by Drane was applied. Of the sampled subjects, 86% (6031) participated in the survey. Two different definitions of asthma were adopted: 1) prevalence of asthma attack in the last 12 months; 2) prevalence of asthma attack or treatment with antiasthmatic drugs, or both wheezing apart from the common cold and wheezing with shortness of breath. This combination of symptoms has been called current asthma. According to these definitions, the prevalence of asthma attack was 3.47% (3.74% in men and 3.14% in women), and the prevalence of current asthma was 5.01% (5.07% in men and 4.90% in women). The lowest prevalence was found in Pavia; the highest in Turin. Our findings support the hypothesis that the difference in prevalence reflects the difference in mortality.

The extracellular deposition of mast cell products is increased in hypertrophic airways smooth muscles in allergic asthma but not in nonallergic asthma.

BACKGROUND: Bronchial asthma is characterized by airways smooth muscle hypertrophy and infiltration of mast cells in the bronchial mucosa. The aim of this investigation was to study the distribution of mast cells in different compartments in the bronchial mucosa of allergic and nonallergic asthma in relation to airways remodeling. METHODS: Bronchial biopsies were obtained from 29 subjects with allergic and nonallergic asthma and healthy controls. The biopsies were stained for mast cells by means of the tryptase specific antibody AA1. Extracellular deposition of mast cell products were judged on a semi-quantitative scale. Mast cells per mm(2) were counted in epithelium, lamina propria and the smooth muscle compartment. Smooth muscle was visualized by actin antibodies and the proportion of staining of the biopsy estimated. Laminin and tenascin layers were visualized by their respective antibodies. RESULTS: Airways smooth muscle thickness was greater in allergic vs nonallergic asthma (P < 0.001). Mast cells were increased in all three compartments in both allergic and nonallergic asthma, with significantly higher numbers in smooth muscles in allergic asthma (P < 0.03). The extracellular deposition of mast cell products was more common in allergic than nonallergic asthma in lamina propria and smooth muscles (P = 0.025; P = 0.002, respectively). In patients with allergic asthma the numbers of mast cells with extracellular deposition of mast cell products were significantly correlated to the thickness of the laminin and tenascin layers. CONCLUSION: Our results suggest that there are large differences between allergic and nonallergic asthmatics as to mast cell activation and airways smooth muscle thickness. Our data implies that mast cells are causally involved in structural alterations in allergic asthma.

Asthma in middle schools: what students have to say about their asthma.

Preadolescence involves cognitive, social, and physiological changes along with changes in the child's environment. During this developmental stage, young adolescents are transitioning into middle school, forming a larger social network, and managing parental expectations for assuming more responsibility for self-care. The impact of these developmental changes on asthma management is not well understood. The purpose of this study was to better understand asthma and asthma management from the perspective of middle school students. A partnership was formed between the university researcher, several school nurses, and a representative of the health department, through the Orange County Asthma Coalition. Funds were secured from the American Lung Association. School nurses helped to identify and recruit 50 middle school students with asthma to participate in focus groups. The focus-group discussions centered on asthma management with implications for intervention development. Analyses sought to identify developmental issues that affect management. Results indicated that the transition to middle school represents a challenge to managing asthma. As compared with the elementary school environment, support structures are broader and more diffuse, physical education is more demanding, and peer pressure is greater. Nevertheless, the desire for greater autonomy and independence in self-care was strong, particularly among eighth graders. Most interventions are designed for either children or adults, without recognizing the important developmental changes that are occurring in preadolescents with implications for asthma management. A school-based intervention in middle school may help students with asthma transition to greater autonomy of care, while easing transition in other domains of life.

Specialist nurse intervention to reduce unscheduled asthma care in a deprived multiethnic area: the east London randomised controlled trial for high risk asthma (ELECTRA).

OBJECTIVE: To determine whether asthma specialist nurses, using a liaison model of care, reduce unscheduled care in a deprived multiethnic area. DESIGN: Cluster randomised controlled trial. SETTING: 44 general practices in two boroughs in east London. PARTICIPANTS: 324 people aged 4-60 years admitted to or attending hospital or the general practitioner out of hours service with acute asthma; 164 (50%) were South Asian patients, 108 (34%) were white patients, and 52 (16%) were from other, largely African and Afro-Caribbean, ethnicities. INTERVENTION: Patient review in a nurse led clinic and liaison with general practitioners and practice nurses comprising educational outreach, promotion of guidelines for high risk asthma, and ongoing clinical support. Control practices received a visit promoting standard asthma guidelines; control patients were checked for inhaler technique. MAIN OUTCOME MEASURES: Percentage of participants receiving unscheduled care for acute asthma over one year and time to first unscheduled attendance. RESULTS: Primary outcome data were available for 319 of 324 (98%) participants. Intervention delayed time to first attendance with acute asthma (hazard ratio 0.73, 95% confidence interval 0.54 to 1.00; median 194 days for intervention and 126 days for control) and reduced the percentage of participants attending with acute asthma (58% (101/174) v 68% (99/145); odds ratio 0.62, 0.38 to 1.01). In analyses of prespecified subgroups the difference in effect on ethnic groups was not significant, but results were consistent with greater benefit for white patients than for South Asian patients or those from other ethnic groups. CONCLUSION: Asthma specialist nurses using a liaison model of care reduced unscheduled care for asthma in a deprived multiethnic health district. Ethnic groups may not benefit equally from specialist nurse intervention.

Development of an asthma specific job exposure matrix and its application in the epidemiological study of genetics and environment in asthma (EGEA).

OBJECTIVES: To develop a method suitable for estimating exposure risks in population studies of asthma from job titles and international codes, by combining a new job exposure matrix (JEM) with the expert judgement approach. The method was applied in the French epidemiological study of the genetics and environment in asthma (EGEA). METHODS: The JEM contains 22 exposure groups including 18 high risk groups based on known risk factors for occupational asthma, divided into high molecular weight agents, low molecular weight agents, and mixed environments. After applying the JEM to job codes, exposure estimates for each subject were re-evaluated by examining job title texts. Three high risk exposure estimates for asthma were compared: firstly, applying the JEM to original codes (from different coders in each study centre); secondly, applying the JEM to revised codes (from one experienced coder); and thirdly, after reviewing JEM exposure estimates in the light of job title texts. RESULTS: The study comprised 173 cases with asthma and 285 controls (age 18-65). Odds ratios (ORs) for asthma for high risk jobs were 1.0 (95% confidence interval (95% CI) 0.6 to 1.7), applying the JEM to original codes; 1.4 (95% CI 0.8 to 2.3), applying the JEM to revised codes; and 1.7 (95% CI 1.1 to 2.7), applying the JEM and subsequently re-evaluating exposure estimates from job title texts. Asthma ORs were 1.4 (95% CI 0.6 to 2.9) for high molecular weight agents, 2.3 (95% CI 1.2 to 4.4) for low molecular weight agents, and 2.1 (95% CI 0.9 to 5.2) for mixed environments. CONCLUSIONS: This asthma JEM, when enhanced by expert re-evaluation of exposure estimates from job title texts, may be a useful tool in general population studies of asthma. In this study, a 1.7-fold increase in prevalence odds of high risk exposures was found among asthmatic workers compared with controls, with risk magnitude varying for different classes of exposure.

Outpatient management of childhood asthma by paediatrician or asthma nurse: randomised controlled study with one year follow up.

BACKGROUND: Until now, care provided by asthma nurses has been additional to care provided by paediatricians. A study was undertaken to compare nurse led outpatient management of childhood asthma with follow up by a paediatrician. METHODS: Seventy four children referred because of insufficient control of persistent asthma were randomly allocated to 1 year follow up by a paediatrician or asthma nurse. The main outcome measure was the percentage of symptom-free days. Additional outcome measures were airway hyperresponsiveness, lung function, daily dose of inhaled corticosteroids (ICS), number of exacerbations, number of additional visits to the general practitioner, absence from school, functional health status, and disease specific quality of life. RESULTS: There were no significant differences at the end of the 1 year study period between the two treatment groups in percentage of symptom-free days (mean difference 2.5%; 95% CI -8.8 to 13.8), airway hyperresponsiveness (log10 PD20 0.06; -0.19 to 0.32), functional health status (10.1; -0.3 to 19.8), disease specific quality of life of patients (0.08; -0.9 to 0.7), and disease specific quality of life of caregivers (0.09; -0.2 to 0.3), nor in any other outcome parameters. Most outcome parameters improved considerably over the 1 year study period. These improvements were achieved although the daily dose of ICS was reduced by a mean of 26% compared with the dose received by children at referral. All parents were satisfied with the asthma care received. CONCLUSIONS: After initial assessment in a multidisciplinary clinic, childhood asthma can be successfully managed by an asthma nurse in close cooperation with a paediatrician. During close follow up by paediatrician or asthma nurse, asthma control improved despite a reduction in ICS dose.

Repeaters count: a sentinel method for asthma outbreaks. Barcelona Soybean-Asthma Group.

BACKGROUND: Asthma outbreaks have not been detected in Barcelona, Spain since the epidemic of 1981-7. On 29 October 1994 several subjects attended a Barcelona hospital because of acute attacks of asthma and were identified as former soybean epidemic asthma patients (repeaters), raising the possibility of an asthma soybean-related episode. The usefulness of counting repeaters to evaluate small increases of acute asthma in a non-epidemic period is illustrated. METHODS: A retrospective identification of asthma admissions was performed, pollution filters collected before and after the index day were analysed for contents of low molecular weight soybean allergen, and soybean unloading activities were investigated. RESULTS: There was no epidemic increase of asthma patients during this day in the whole of Barcelona, but an unusually high number were repeaters (seven observed v 0.483 expected). A relationship with increased levels of low molecular weight soybean allergen (U/m3) was detected in the available pollution filters collected the day before and after the index day. Two ships were unloading soybean in the city harbour on the index day. CONCLUSION: Soybean unloading at the harbour of Barcelona released soybean dust and produced a small cluster of emergency room visits for asthma in patients formerly affected by soybean asthma epidemics. It is suggested that counting repeaters could provide the basis for a systematic epidemiological surveillance of sensitised populations.

Interrelationships between diagnosed asthma, asthma-like symptoms, and abnormal airway behaviour in adolescence: the Odense Schoolchild Study.

BACKGROUND: The diagnosis of asthma is based on several characteristics including symptoms and suitable tests of airway lability. However, it is neither clear to what degree various tests and symptoms identify the same subjects, nor how these characteristics are best combined to diagnose asthma. The interrelationships between physician-diagnosed asthma, asthma-like symptoms, and abnormal airway function, as defined by four commonly used tests, have therefore been assessed. METHODS: A population based sample of 495 Danish schoolchildren aged 12-15 years, comprising 292 randomly selected subjects and 203 subjects considered at risk of having or developing asthma, was examined. Symptoms and background information were recorded by questionnaire. The test panel consisted of baseline forced expiratory volume in one second (FEV1%), provocation with treadmill exercise (EXE) and with inhaled methacholine (PD15), and monitoring of peak expiratory flow (PEF) twice daily for two weeks. RESULTS: The sensitivity for diagnosed asthma was highest for PD15 followed by PEF monitoring, whereas specificity for asthma or asthma-like symptoms was marginally higher with the other two tests. Most symptomatic subjects with any positive test were identified by PD15 alone (75%) or in combination with PEF monitoring (89%). PEF variability was more susceptible to treatment with inhaled steroids than the PD15 index. Although inter-test agreement was weak (kappa < 0.40 for all pairs), significant associations were found between PD15 and EXE, PEF and EXE, and FEV1% and PD15. CONCLUSIONS: The agreement between the four tests was weak. In particular, PEF variability and methacholine responsiveness seem to identify different varieties of airway pathophysiology. The combined use of methacholine provocation testing and PEF monitoring may be helpful as an epidemiological screening tool for asthma.

The BC Community Pharmacy Asthma Study: A study of clinical, economic and holistic outcomes influenced by an asthma care protocol provided by specially trained community pharmacists in British Columbia.

OBJECTIVES: Despite advances in recent years, asthma morbidity and mortality have been noted to be on the increase in the past decade. The present study examined the failures and recommendations of past studies and introduced a new milieu for asthma care--the community pharmacy. The study incorporated a care protocol with the important ingredients of asthma education on medications, triggers, self-monitoring and an asthma plan, with pharmacists taking responsibility for outcomes, assessment of a patient's readiness to change and tailoring education to that readiness, compliance monitoring and physician consultation to achieve asthma prescribing guidelines. METHODS: Thirty-three pharmacists in British Columbia, specially trained and certified in asthma care, agreed to participate in a study in which experienced pharmacists would have asthma patients allocated to enhanced (pharmaceutical) care (EC) or usual care (UC). Pharmacists less experienced were clustered by geography and had their pharmacies randomized to two levels of care; each pharmacy then had patients randomized to EC versus control, UC versus control or EC versus UC depending on their pharmacy randomization. Six hundred thirty-one patients provided consent, of which 225 in EC or UC were analyzed for all outcomes. Patients were followed for one year. RESULTS: Compared with patients in the UC group, the results of those in the EC group were as follows: symptom scores decreased by 50%; peak flow readings increased by 11%; days off work or school were reduced by approximately 0.6 days/month; use of inhaled beta-agonists was reduced by 50%; overall quality of life improved by 19%, and the specific domains of activity limitations, symptoms and emotional function also improved; initial knowledge scores doubled; emergency room visits decreased by 75%; and medical visits decreased by 75%. A patient satisfaction survey revealed that the population was extremely pleased with their pharmacy services. Cost analysis reinforces the EC model, which is more cost effective than UC in terms of most direct and indirect costs in asthma patients. CONCLUSION: Specially trained community pharmacists in Canada, using a pharmaceutical care-based protocol, can produce impressive improvements in clinical, economic and humanistic outcome measures in asthma patients. The health care system needs to produce incentives for such care.

Asthma control in Canada remains suboptimal: the Reality of Asthma Control (TRAC) study.

BACKGROUND: Two Canadian studies showed that 55% of patients with asthma had daily symptoms (in 1996) and that 57% of patients suffered from poorly controlled asthma (in 1999). OBJECTIVES: To assess the state of asthma control of adult Canadians, and asthma knowledge and practices of Canadian physicians actively involved in the care of patients with asthma. METHODS: Telephone interviews were conducted with adults 18 to 54 years of age who had been diagnosed with asthma at least six months before the survey, who did not have chronic obstructive pulmonary disease and who had a smoking history of fewer than 20 pack-years. Physicians were surveyed by telephone and mail. The surveys took place between April and August 2004. RESULTS: Almost all (97%) of the 893 patients believed that they had controlled asthma; however, only 47% had controlled disease according to symptom-based guideline criteria. Just 39% of 463 physicians based their treatment recommendations on the Canadian asthma guidelines most or all of the time, despite having a high awareness of them. Only 11% of patients had written action plans, and one-half of patients with action plans did not use them regularly. Almost three-quarters of patients expressed concerns about taking inhaled corticosteroids. CONCLUSIONS: Since the last major national survey, guideline implementation has not resulted in significant changes in asthma-related morbidity. Effective means of knowledge transfer should be developed and implemented to improve the translation of guideline recommendations into care.

The risk of asthma attributable to occupational exposures. A population-based study in Spain. Spanish Group of the European Asthma Study.

The prevalence of occupational asthma has usually been estimated from registers of cases rather than population surveys. We examined the causes and derived estimates of the risk of asthma attributable to occupational exposures in a randomly selected population of five areas of Spain. The study is part of the EC Respiratory Health Survey and comprises 2,646 subjects age 20 to 44 yr. Bronchial reactivity was determined in 1,797 subjects and atopy in 2,164. Twenty-one occupational sets were defined using information on current occupation, or in subjects reporting change of occupation due to respiratory problems, their occupation at that time. The highest risk of asthma was observed for laboratory technicians, spray painters, bakers, plastics and rubber workers, welders, and cleaners. The risk of asthma attributed to occupational exposures after adjusting for age, sex, residence, and smoking status was 5.0% when asthma was defined as "bronchial reactivity and a report of wheezing or whistling in the chest during the last 12 mo," and 6.7% when asthma was defined as "bronchial reactivity and a report of asthma-related symptoms or medication." Estimates of the attributable risk for adult onset asthma were higher. Occupational exposures constitute a substantial cause of asthma in the young adult Spanish population.

Extended haplotype in the tumor necrosis factor gene cluster is associated with asthma and asthma-related phenotypes.

RATIONALE: Tumor necrosis factor is a proinflammatory cytokine found in increased concentrations in asthmatic airways. The TNF-alpha (TNF) and lymphotoxin-alpha (LTA) genes belong to the TNF gene superfamily located within the human major histocompatibility complex on chromosome 6p in a region repeatedly linked to asthma. The TNF position -308 and LTA NcoI polymorphisms are believed to influence TNF transcription and secretion, respectively. OBJECTIVES: This study sought to determine whether polymorphisms in TNF or LTA, or in TNF-LTA haplotypes, are associated with asthma and asthma phenotypes. METHODS: We genotyped the TNF -308 and LTA NcoI polymorphisms, and two other haplotype-tagging polymorphisms in the TNF and LTA genes, in 708 children with mild to moderate asthma enrolled in the Childhood Asthma Management Program and in their parents. Using an extension of the family-based association tests in the PBAT program, each polymorphism was tested for association with asthma, age at onset of asthma, and time series data on baseline FEV(1) % predicted, postbronchodilator FEV(1) % predicted, body mass index, and log of PC(20). MEASUREMENTS AND MAIN RESULTS: Although no associations were found for the individual single-nucleotide polymorphisms, the haplotype analysis found the LTA NcoI_G/LTA 4371T/TNF -308G/TNF 1078G haplotype to be associated with asthma and with all five phenotype groups. CONCLUSIONS: We conclude that it is unlikely that the TNF -308 or LTA NcoI polymorphisms influence asthma susceptibility individually, but that this haplotype of variants may be functional or may be in linkage disequilibrium with other functional single-nucleotide polymorphisms.

Bronchiolitis to asthma: a review and call for studies of gene-virus interactions in asthma causation.

Viral infections are important causes of asthma exacerbations in children, and lower respiratory tract infections (LRTIs), caused by viruses such as respiratory syncytial virus (RSV) and rhinovirus (RV), are a leading cause of bronchiolitis in infants. Infants hospitalized with bronchiolitis are at significantly increased risk for both recurrent wheezing and childhood asthma. To date, studies addressing the incidence of asthma after bronchiolitis severe enough to warrant hospitalization have focused almost exclusively on RSV, but a number of recent studies suggest that other respiratory pathogens, including RV, may contribute as well. It is not known whether viral bronchiolitis directly contributes to asthma causation or simply identifies infants at risk for subsequent wheezing, as from an atopic predisposition or preexisting abnormal lung function. Alternatively, the properties of the infecting virus may be important. Thus, many possible determinants exist that may contribute to the severity of bronchiolitis and the subsequent development of asthma. One such determinant is the potential involvement of genetic susceptibility loci to asthma after viral bronchiolitis, a critical area that is just beginning to be evaluated. By clarifying the roles of both host- (genetic) and virus- (environment) specific factors that contribute to the frequency and severity of viral LRTI, it may be possible to determine if severe LRTIs cause asthma, or if asthma susceptibility predisposes patients to severe LRTI in response to viral infection. Characterizing these relationships offers the potential of identifying at-risk hosts in whom preventing or delaying infection could alter the phenotypic expression of asthma.

The CGHA asthma management program and its effect upon pediatric asthma admission rates.

Asthma is the most common reason for admission to the hospital for children nationally. This hospitalization rate is stable despite availability of appropriate outpatient treatments. Our Cincinnati Group Health Associates (CGHA) asthma management program has evolved since 1989. We have measured our pediatric population along with asthma admissions since 1993. Our admission pattern is compared to the community in general and to our managed care population in particular. Our urban center's admission pattern is also studied. Our CGHA pediatric asthma admissions have been declining steadily over the 1993-2000 period by 60%. This decrease is in contrast to national trends in this time period. Comparison to total admissions from 1993 through 2000 still shows a 50% decline whether 0-18 years or 0-5 years is studied. Our urban pediatric center also had a fall in pediatric asthma admission rates of 80% in this time frame; all of these results are statistically significant. Our major managed care network also showed a decline of 55% in pediatric asthma admissions from 1996 to 1999. Our CGHA asthma management program has had a positive influence on our pediatric asthma admission rates. This effect is favorable in comparison to national trends in pediatric asthma admissions. This trend is independent of disease acuity, region of the city where patients live, insurance selection, or age.

Internet telehealth for pediatric asthma case management: integrating computerized and case manager features for tailoring a Web-based asthma education program.

This article reports on the development of a personalized, Web-based asthma-education program for parents whose 4- to 12-year-old children have moderate to severe asthma. Personalization includes computer-based tailored messages and a human coach to build asthma self-management skills. Computerized features include the Asthma Manager, My Calendar/Reminder, My Goals, and a tailored home page. These are integrated with monthly asthma-education phone calls from an asthma-nurse case manager. The authors discuss the development process and issues and describe the current randomized evaluation study to test whether the year-long integrated intervention can improve adherence to a daily asthma controller medication, asthma control, and parent quality of life to reduce asthma-related healthcare utilization. Implications for health education for chronic disease management are raised.
