[Relationship between asthma or asthma-related symptoms and school problems among French children attending kindergarden].

BACKGROUND: The impact of chronic respiratory symptoms on school performance has been studied less than its impact on children's health. Our survey explored the relationship between chronic respiratory symptoms and school problems among children attending kindergarten. It assessed the impact of school absenteeism, sport practise in a club and health care access for school problems among pupils with chronic respiratory symptoms. METHODS: A population-based study was carried out by school physicians on a representative sample of pupils attending third-year kindergarten, in Alsace - France. Assessments included school problems, sociodemographic and health care access characteristics. Health conditions, notably chronic respiratory symptoms, were asked to include the pupils in one of the three study groups: physician-diagnosed asthma, asthma-related symptoms not associated with diagnosed asthma, and without current health problems (controls). Logistic regression was used to compare the odds ratio of school problems for the three study groups, overall and stratified by income. RESULTS: The 2,632 included pupils aged 5 to 6 Years, were assigned to the three groups according to their respiratory status: 179 with diagnosed asthma, 176 with asthma related symptoms and 2,277 healthy pupils. Diagnosed asthma was not linked with school problems. The overall association between asthma related symptoms and school problems was significant (OR=1.5, 95% CI: 1.0-2.2). After adjustment, this association persisted among pupils whose mother's education level was intermediary (technical or vocational diploma) (OR=2.3, 95% CI: 1.2-4.6). Among the diagnosed asthma group, pupils practising a sport in a club had less school problems than those not taking part in sports (ORadjusted=0.2, 95% CI: 0.03-0.8). CONCLUSION: In our study, asthmatic children were not at higher risk of school problems. So developing programs preventing school problems which focus on asthmatic children is not needed. Among the pupils having a mother with an intermediary education level, asthma-related symptoms were associated with school problems. It is important to identify unknown asthmatics to institute to treatment for their respiratory symptoms in order to prevent the consequences of the functional impact of asthma on their scholarship.

Prevalence of asthma and asthma-like symptoms in Athens, Greece.

Asthma is a common chronic condition and there is evidence that its prevalence may be rising. The European Respiratory Health Survey (ECRHS) was planned to produce comparable data on asthma epidemiology in Europe. In Greece, in particular, a similar study has not been conducted previously and no epidemiological data are available on adult asthma prevalence. Furthermore, the role of air pollution in the pathogenesis of asthma is currently an issue of debate. Athens is a city with high air pollution, and a study of asthma epidemiology in this city may confirm or refute a possible link with the expression of asthma. A questionnaire developed by the ECRHS was sent to a random sample of 3533 households in Peristeri, an industrialized borough of Athens. Responses were received from 2774 households (response rate 78%). Of all the data on individual subjects, only those from 3325 adults aged 20-44 years were considered, according to the study protocol. The self-reported current prevalence of asthmatic attacks and asthma-like symptoms were as follows: asthma attack 2.4%, use of asthma medication 2.1%, awakening by shortness of breath 5.6%, awakening by cough 17.8%, wheezing 15.8% and nasal allergies 18.4%. It is concluded that the prevalence of asthma and related symptoms in this region of Athens is rather low, despite the high air-pollution levels in the city.

Correlation between nasal symptoms and asthma severity in patients with atopic and nonatopic asthma.

BACKGROUND: The association between allergic rhinitis and asthma has been well recognized, and it has been postulated that rhinitis may worsen asthma. OBJECTIVE: To investigate the severity of asthma among patients with atopic and nonatopic asthma with and without nasal symptoms. METHODS: Atopic asthmatic patients and nonatopic asthmatic patients were identified from the records of a university-based asthma clinic. A comparison of demographic clinical features was made within and between these 2 asthmatic groups, dichotomized according to the presence or absence of rhinitis. RESULTS: A total of 178 patients were classified as having atopic asthma and 218 as having nonatopic asthma. The atopic asthmatic patients with nasal symptoms compared with those without had a higher mean forced expiratory volume in 1 second (FEV1), a higher forced vital capacity (FVC), and a higher FEV1/FVC ratio, used fewer oral steroids, and had fewer hospitalizations. The nonatopic asthmatic patients with nasal symptoms compared with those without used more inhaled steroids (and they were also more likely to have nasal polyps on examination). Atopic, relative to nonatopic, asthmatic patients were younger, had a longer duration of asthma, had a higher FEV1/FVC ratio, and took fewer oral steroids. CONCLUSION: Contrary to current hypotheses, in this study the severity of asthma among atopic asthmatic patients was less in those with nasal symptoms. Conversely, among the nonatopic asthmatic patients, asthma was more severe among those with nasal symptoms than those without nasal symptoms.

Different airway responsiveness profiles in atopic asthma, nonatopic asthma, and Sjögren's syndrome. BHR Study Group. Bronchial hyperresponsiveness.

BACKGROUND: Different mechanisms may underlie bronchial hyperresponsiveness (BHR) in different diseases. The aim of this study was to investigate the bronchial responsiveness profile produced by three different challenge tests, methacholine, a direct stimulus, and two indirect stimuli, adenosine 5'-monophosphate (AMP) and cold air, in subjects with asthma and patients with Sjögren's syndrome. METHODS: The study population comprised 40 adult patients with asthma, 18 subjects with Sjögren's syndrome, and 20 controls. Blood samples were collected before each challenge for measurements of serum eosinophil peroxidase (S-EPO) and eosinophil cationic protein (S-ECP). The investigated subjects recorded peak expiratory flow and kept a symptom diary. RESULTS: Atopic subjects with asthma were significantly more hyperresponsive to AMP than nonatopic subjects with asthma (P=0.01) and subjects with Sjögren's syndrome (P=0.02). No difference was seen between atopic and nonatopic subjects with asthma in the case of challenges with methacholine or cold air. In atopic subjects with asthma, a significant correlation was found between challenges with methacholine and AMP (r=0.91, P=0.0001) and methacholine and cold air (r=0.83, P=0.004), but, in nonatopic subjects with asthma, no significant correlation was seen between methacholine and AMP or cold air challenges. In atopic subjects with asthma, the dose-response slope for AMP was correlated to S-EPO (r= -0.56; P = 0.01) and S-ECP (r= -0.51, P = 0.02), while no correlation between BHR and inflammation markers was found in the two other patient groups. CONCLUSIONS: The results of this study suggest that patients with asthma and subjects with Sjögren's syndrome display different bronchial responsiveness profiles for different challenge agents. Atopic subjects with asthma are more hyperresponsive to AMP than nonatopic subjects and patients with Sjögren's syndrome. More than one challenge may be required to detect different aspects of bronchial responsiveness.

Using Global Initiative for Asthma guidelines to assess asthma severity in populations.

The classification of asthmatics into severity categories is a crucial issue for assessing the asthma burden within a community, in which a proportion of patients is currently treated. There is no epidemiological method currently available. The Global Initiative for Asthma (GINA) was used to classify 4,362 patients aged 16-45 yrs (49% males, 42% taking inhaled corticosteroids), enrolled by 545 chest specialists in France with short standardized questionnaires including forced expiratory volume in one second (FEV1) measurements. Two independent GINA classifications were combined, one based only on symptoms and FEVI, and the other based only on current medication, to construct a final "symptom-FEV1 medication" classification. Almost 40% of the patients classed as step 1, 30% of those classed as step 2 and 13% of those classed as step 3 in the initial symptom-FEV1-classification, were allocated to categories of higher severity in the final classification. The approach was validated by showing that the proportions of: 1) patients considered by the physicians as having severe or moderately severe asthma; 2) patients with a history of hospital admission for asthma; and 3) patients with a history of emergency department visits for asthma, increased with severity steps in the final classification, for each step of the two initial independent classifications. The treatment manage plan in the Global Initiative for Asthma was not developed for assessing severity of asthma but rather to describe the recommended therapy for asthma with different severity. This is the first attempt to assess the severity of asthma in a large population of asthmatics mostly taking treatment, based on the Global Initiative for Asthma guidelines. The authors propose this simple and pragmatic procedure for a potential classification which should be put to the test in other studies.

Relationship between lung function and asthma symptoms in patients with difficult to control asthma.

Several studies have demonstrated a poor relationship between measures of asthma control and lung function in patients with asthma. We sought to examine this relationship in a cohort of difficult to control asthmatics attending a hospital outpatient clinic. FEV1 % and asthma control scores (ACSs) were measured at the first clinic visit and at a follow-up visit. A total of 59 patients took part in the study. At the initial visit, FEV1 % correlated with limitation of activity (p = 0.002), shortness of breath (p = 0.02), wheezing (p = 0.029), and ACS (p = 0.014). However, at follow-up, there was no correlation between FEV1 % and any measured index of asthma control. When patients with severe fixed airflow obstruction were excluded from the analysis (n = 16), FEV1 % at follow-up became significantly correlated with night waking (p = 0.02), wheezing (p = 0.05), and ACS (p = 0.036). The improvement in asthma control score at follow-up was significantly and strongly associated (r = 0.51 for total asthma control, p < 0.001) with the improvement in lung function in patients without severe fixed airflow obstruction. Lung function was not associated with any measure of asthma control in patients with severe fixed airflow obstruction. FEV1 % correlates well with asthma symptoms in difficult asthma patients with poor control but not when control improves. This loss of relationship is due to subjects with severe fixed airflow obstruction where good subjective control does not exclude the presence of significant obstruction. How severe fixed airflow obstruction should be prevented, delayed, or managed in asthma requires further research.

Gender differences in IgE-mediated allergic asthma in the epidemiology and natural history of asthma: Outcomes and Treatment Regimens (TENOR) study.

BACKGROUND: The TENOR study consists of a large cohort of subjects with severe or difficult-to-treat asthma. The objective of this analysis was to evaluate demographic and clinical characteristics of subjects 12 years of age or older with immunoglobulin E (IgE)-mediated allergic asthma (skin test positive with an IgE level = 30 to =700 IU/mL), and specifically, to assess gender differences in this cohort. METHODS: A total of 4,756 subjects were enrolled by 283 US study sites between January and October 2001. Of those subjects 12 years or older at baseline with an IgE measure and who were skin tested (n = 2,843), 1,783 (63%) were skin test positive and had an IgE level between = 30 to = 700 IU/mL. RESULTS: Compared to males, females reported significantly greater healthcare utilization (steroid bursts in previous 3 months: 50% vs 42%, p < 0.001; unscheduled office visits in previous 3 months: 50% vs 36%, p < 0.0001; missed 1+ days of work/school in previous 2 weeks: 14% vs 10%, p < 0.01). Females also reported significantly more asthma control problems and lower asthma-related quality of life (4.6 +/- 1.3 vs 5.2 +/- 1.2; p < 0.0001); the difference was clinically meaningful. Asthma triggers and allergic comorbidities, such as allergic rhinitis and atopic dermatitis, were more common in female subjects. Despite their overall worse health outcomes, female subjects demonstrated better lung function, had similar treatment patterns, and showed no differences in physician-assessed asthma severity when compared with males. CONCLUSIONS: The reasons for these gender differences in subjects with IgE-mediated allergic asthma are complex, but results from this analysis suggest that detailed evaluations of asthma patients, including symptom-related questions and asthma-related healthcare utilization, are needed to accurately assess asthma severity and control.

The relationship of frequency of follow-up visits to asthma outcomes in patients with moderate persistent asthma.

BACKGROUND: Although regular follow-up is recommended for patients with asthma, the optimal frequency of such follow-up has not been defined. The purpose of this study was to evaluate the relationship of the interval between routine physician visits to asthma outcomes in patients with moderate persistent asthma. METHODS: The study population was a volunteer sample of subjects aged 18 years or older with moderate persistent asthma requiring at least moderate doses of inhaled corticosteroids who were followed for at least 6 months by one of two allergists in a large staff model HMO. Subjects were randomized to one of three groups: 1) monthly physician visits, 2) semi-annual physician visits, and 3) semiannual physician visits and monthly nurse phone calls. All subjects were advised to call their physician for questions or increased symptoms. The primary outcome variable was total asthma quality of life measured at baseline, 6 months and 12 months. Other outcome variables included specific asthma quality of life domains; spirometry, global asthma rating, satisfaction with treatment rating, and asthma resource and medication utilization during the one year of follow-up. RESULTS: The final cohort included 29 patients per group. There were no significant differences between groups in baseline demographics, smoking history, spirometry, asthma quality of life, global rating, or satisfaction with treatment rating. As per the protocol, patients in the monthly physician visit group made significantly more routine visits during the study than other patients (P<.0001), but there were no other significant differences between groups in any of the other outcome variables at 6 months, 12 months, or during the year of the study. CONCLUSION: Patients with the characteristics of those in this study do not need routine follow-up visits more often than every 6 months. Further studies will be necessary to determine optimal follow-up intervals for patients with other degrees of asthma severity and for those followed in other settings.

Relation between breastfeeding and the prevalence of asthma : the Tokorozawa Childhood Asthma and Pollinosis Study.

Many risk factors for asthma have been proposed including age, gender (male), smoking, and family history of asthma. The importance of breastfeeding to childhood asthma is a controversial issue. The present study investigated the relation between breastfeeding and the prevalence of asthma among a childhood population. The subjects were 25,767 students, representing all public elementary and junior high schools in Tokorozawa, Japan (age range, 6--15 years). The study population included 2,315 students with asthma and 21,513 controls. Participants' parents completed the Japanese version of the American Thoracic Society and Division of Lung Diseases, National Heart, Lung, and Blood Institute, questionnaire for children adopted by the Japanese Environmental Agency in 1998. The authors added supplementary questions on the parental history of asthma and feeding patterns from the age of 0--3 months. The risk of breastfeeding for asthma was compared with that of artificial feeding. After adjustment for age, gender, parental smoking status, and parental history of asthma, a significantly higher prevalence of asthma was noted among children who had been breastfed (adjusted odds ratio = 1.198; 95% confidence interval: 1.054, 1.363; p for trend < 0.01). The results indicated that breastfeeding in infancy might be related to the higher prevalence of asthma during preadolescence.

A cross-sectional study evaluating the relationship between cortisol suppression and asthma control in patients with difficult asthma.

AIM: To examine the relationship between cortisol suppression and asthma symptoms in patients with difficult asthma. METHODS: Patients, referred to a specialist difficult asthma service and who fulfilled the criteria for difficult asthma, were recruited to the study in a sequential, unselected manner. At each clinic visit, all patients completed a validated asthma control questionnaire. For measuring cortisol suppression, early morning urinary cortisol [corrected for creatinine to give urinary cortisol creatinine ratio (UCC ratio)] was used. The urine samples were collected and stored at -70 degrees C until ready for analysis. Urinary cortisol was extracted (solid-phase extraction) and analysed using high-performance liquid chromatography. The Pearson correlation coefficient was used for correlation analysis while t-tests were used for between-group differences for normally distributed data. If the data were not normally distributed, nonparametric statistics were used. A P-value < 0.05 was considered statistically significant. RESULTS: During the study period all the patients who attended the difficult asthma clinic and fulfilled the criteria for difficult asthma (n = 66) agreed to take part in the study. There were moderate to strong and significant associations between several measures of asthma control and UCC ratio. The correlation coefficient with five indicators of asthma control ranged between 0.3 and 0.5 (P < 0.05). CONCLUSIONS: We have demonstrated a relationship between cortisol suppression and asthma control in difficult asthmatics on high-dose steroid therapy. We have proposed a model based on the relationship between symptom control and cortisol suppression, whereby both adherence and therapeutic adjustments could potentially be made. A properly controlled prospective clinical trial should examine the utility of this approach in clinical practice.

Early effects of Asthma Prevention Program on asthma diagnosis and hospitalization in urban population of Poland.

BACKGROUND: Asthma is one of the commonest public health problems in Poland and the commonest chronic disorder in children. Lodz Regional Health Insurance Fund was a sponsor of the Prevention Asthma Program in 2000-03, directed at increasing early detection and providing optimal treatment of allergies by specialists in children. METHODS: All funds were divided between 127 primary and 12 specialized care centres participated in the programme. Primary care centre goals were: anamnestic information, mapping of allergy-causing factors, repeated auscultation of the lungs, bronchial dilation test, peak expiratory flow (PEF) measurement at the clinic and at home for 2 weeks. After preliminary diagnosis patients have been send to specialized centres. Specialized care centre goals were as follows: skin testing, spirometry, repeated bronchial dilation test, determination of eosinophilic white blood cells and eosinophil cationic protein (ECP) in blood. RESULTS: Increasing trend of new asthma diagnosis, expressed per 1000 inhabitants, was observed from 0.99 in 2000 to 2.19 in 2003. In the first year of Asthma Prevention Program, we observed more hospital episodes because of asthma exacerbation in comparison with year 1999 but from the second year of programme we showed systematically decreasing number of hospital episodes as a result of asthma exacerbation from 1.48 in 2000 to 0.84 in 2003. We found significantly decreasing trend in duration of hospitalization due to asthma exacerbation (P = 0.001). CONCLUSIONS: Effects of this programmes are: early identification of allergic diseases, mainly asthma, reduced number and shorter duration of hospitalization because of asthma exacerbation and establishing new Asthma Schools Education.

Bronchial asthma and the short-term quality of life: follow-up study of childhood bronchial asthma in Hungary.

The aim of our study is to determine and describe the current short-term health-related quality of life of recent adult patients who had bronchial asthma in childhood. Our objective was to investigate if symptom control in bronchial asthma could be in conflict with general quality of life. We made a follow-up study of 152 patients (105 male, 47 female) over the age of 30 (31-55 yr) who were allergic asthmatics in childhood. The patients' current symptoms and short-term quality of life were evaluated by a questionnaire. The patients developed asthmatic symptoms by age 4.4 (0.5-13) years on the average. Now 60% (91 persons) have no symptoms. They became symptom-free between 3 and 41 yr of age (mean = 14.2 +/- 8.2). Amongst the currently asthmatic patients (58 patients, 38%), 34 patients (22%) belong to the Global Initiative for Asthma (GINA) I, nine patients (6%) to the GINA II, five patients (3.3%) to the GINA III, and five patients (3.3%) to the GINA IV classification. Five patients (3.3%) did not specify their own symptoms. Three persons (2%) did not answer this question. Symptomatic patients reached 5.28 on the Juniper Asthma Quality of Life Questionnaire, while their asymptomatic peers scored statistically higher with 6.8 on the scale. Amongst the symptomatic patients, the most limited areas were: 'bothered by heavy breathing', 'had to avoid a situation or environment because of dust', 'experienced difficulty breathing out as a result of asthma', 'experienced asthma symptoms as a result of the weather or air pollution outside'. They were least 'concerned about medication', 'frustrated as a result of their asthma', they were least limited in 'going outside because of the weather or air pollution'. The most problematic areas for the symptom-free patients were 'had to avoid a situation or environment because of dust', 'had to avoid a situation or environment because of cigarette smoke', 'experiencing asthma symptoms as a result of being exposed to dust and the 'need to clear throat'. It seems that having no asthma symptoms is not equal to having a good quality of life for asthmatic patients. Moreover, symptom control in bronchial asthma is in conflict with quality of life, as many prophylactic measures to prevent exposure to allergens also restrict the patient's life.

Addressing asthma in Texas: development of a school-based asthma surveillance program for Texas elementary schools.

To address asthma in the state, in October 2000, the Texas Department of State Health Services (DSHS) and the American Lung Association of Texas held a joint meeting of asthma professionals from across the state, with a primary purpose of identifying major issues and potential strategies and actions to be taken. These discussions became the basis of the 2001 Texas State Asthma Plan, which has since been adopted to guide state efforts in asthma surveillance, management, education, and advocacy. The primary purpose of this project, which was conducted with and funded by the DSHS and the Centers for Disease Control and Prevention, has been to develop and implement an asthma surveillance program for Texas school-aged children. The program has been implemented with a sample (n = 42,409) of students from the Texas Education Agency's region IV. An important goal has been to determine the feasibility of conducting school-based statewide asthma surveillance and assist with establishing a network for ongoing, systematic collection, analysis, interpretation, and dissemination of asthma data. This project is expected to become part of a wider asthma surveillance network that will include mortality, hospital discharge, and Behavioral Risk Factor Surveillance System (BRFSS) data. It will also provide information not typically captured by surveillance programs, including the BRFSS, which rely heavily upon a previous diagnosis of asthma to determine both lifetime and current prevalence of asthma. Results from this project indicate that such reliance on a previous diagnosis may considerably underestimate the prevalence of disease-particularly in the Latino population

Measurement of psychological distress in asthma and asthma management programmes.

The Asthma Bother Profile assesses one of the components of asthma experience: asthma distress. An initial questionnaire was constructed from the content of earlier asthma quality of life research and modified by comments of 32 asthmatics in focus groups. Psychometric analysis of responses of 131 asthmatics to the final questionnaire showed that the 15 ¿bother items' constitute a unidimensional measure of asthma distress with high internal consistency, and the seven ¿management items' assess the patient's confidence of asthma knowledge, perception of the quality of care and confidence in managing asthma attacks. Patients who had attended a self-management clinic reported more knowledge of asthma, more bother from treatment but not significantly less bother in other contexts. Knowledge about when to call the doctor but not knowledge about medicine or asthma was correlated with total bother. Self-management programmes that encourage problem-focused coping strategies may not reduce asthma distress unless distress reduction counselling is included within the education programme.

Screening a state middle school for asthma using the free running asthma screening test.

The free running asthma screening test (FRAST) was used to screen children in a state middle school during a normal physical education lesson. The test was conducted by the teachers with a general practitioner available via a radiopager. Of the 249 children attending the school, aged 8-12 years, 237 (95%) were tested. Twenty two (9%) children were known to have asthma, of whom 18 were tested. Thirty one children had a significant decrease (> 15%) in their peak expiratory flow rate (PEFR) after exercise. Six of these children were known to have asthma, indicating that their asthma treatment may be suboptimal. A further six children assessed clinically had false positive results. The 31 children with significant decreases in their PEFR were matched for age and sex with a control group of 30 children who were considered to have a normal result. Of the control group, one child had clinical asthma. In total, 19 (8%) new cases of asthma were identified, giving an overall prevalence of asthma in the school of 16%. These results indicate that it is feasible to screen schools for asthma using the FRAST. Children with undiagnosed asthma can be identified and the control of children with known asthma monitored.

Risk factors for death from asthma, chronic obstructive pulmonary disease, and cardiovascular disease after a hospital admission for asthma.

BACKGROUND: Patients with asthma have an increased risk of death from causes other than asthma. A study was undertaken to identify whether severity of asthma, its treatment, or associated co-morbidity were associated with increased risk of death from other causes. METHODS: Eighty five deaths from all causes occurring within three years of discharge from hospital in a cohort of 2242 subjects aged 16-64 years admitted for asthma were compared with a random sample of 61 controls aged <45 years and 61 aged >/=45 years from the same cohort. RESULTS: Deaths from asthma were associated with a history of clinically severe asthma (OR 6.29 (95% CI 1.84 to 21.52)), chest pain (OR 3.78 (95% CI 1.06 to 13.5)), biochemical or haematological abnormalities at admission (OR 4.12 (95% CI 1.36 to 12.49)), prescription of ipratropium bromide (OR 4.04 (95% CI 1.47 to 11.13)), and failure to prescribe inhaled steroids on discharge (OR 3.45 (95% CI 1.35 to 9.10)). Deaths from chronic obstructive pulmonary disease (COPD) were associated with lower peak expiratory flow rates (OR 2.56 (95% CI 1.52 to 4.35) for each 50 l/min change), a history of smoking (OR 5.03 (95% CI 1.17 to 21.58)), prescription of ipratropium bromide (OR 7.75 (95% CI 2.21 to 27.14)), and failure to prescribe inhaled steroids on discharge (OR 3.33 (95% CI 0.95 to 11.10)). Cardiovascular deaths were more common among those prescribed ipratropium bromide on discharge (OR 3.55 (95% CI 1.05 to 11.94)) and less likely in those admitted after an upper respiratory tract infection (OR 0.21 (95% CI 0.05 to 0.95)). Treatment with ipratropium bromide at discharge was associated with an increased risk of death from asthma even after adjusting for peak flow, COPD and cardiovascular co-morbidity, ever having smoked, and age at onset of asthma. CONCLUSIONS: Prescription of inhaled steroids on discharge is important even for those patients with co-existent COPD and asthma. Treatment with ipratropium at discharge is associated with increased risk of death from asthma even after adjustment for a range of markers of COPD. These results need to be tested in larger studies.

The costs of implementing the 1999 Canadian Asthma Consensus Guidelines recommendation of asthma education and spirometry for the family physician.

BACKGROUND: National and international asthma guidelines recommend that patients with asthma be provided with asthma education and spirometry as a component of enhanced asthma care. The cost of implementing these interventions in family physician practices is not known. OBJECTIVE: The objective of the present study was to determine the cost of providing recommended asthma care to adult patients in the family practice setting. METHODS: The present study was conducted using three scenarios of care in family practice. Small, medium and large asthmatic patient populations were used. The incremental costs of implementing enhanced asthma care based on the Canadian Asthma Consensus Guidelines, including the provision of spirometry and asthma education in both group and individual sessions, and the resources required for these interventions were calculated for each scenario. RESULTS: For a physician with 50 asthmatic patients, the cost of providing enhanced asthma care with spirometry and group education sessions was approximately 78 dollars per patient in the first year of implementation. For individual sessions, the cost increased to 100 dollars per patient for the first year. If the physician had 100 asthmatic patients, the per patient cost would decrease; however, the overall cost of the program would be 7,000 dollars. CONCLUSIONS: The costs of providing enhanced asthma care are significant. In most cases, physicians are inadequately reimbursed (or not reimbursed) for these interventions. In light of the evidence of the effectiveness of these interventions, health insurance plans should consider adding these services to fee schedules.

Influence on asthma morbidity of asthma education programs based on self-management plans following treatment optimization.

The objective of this study was to evaluate the effectiveness of an asthma education program on morbidity, knowledge, and compliance with inhaled corticosteroid treatment using a prospective, randomized, controlled, one-year-before/one-year-after protocol. After rigorous optimization of asthma therapy under the care of respirologists, patients were assigned to one of three groups: Group C (control group: no formal education), Group P (education and action plan based on peak-flow monitoring), and Group S (education with action plan based on monitoring of asthma symptoms). A total of 188 subjects with moderate to severe asthma were enrolled and 149 completed the study. Asthma morbidity decreased significantly in all groups (p = 0.001). Mean values one-year-before/one-year-after in Groups C, P, and S were: unscheduled medical visits, 2.4/0.8, 2.3/0.7, and 1.9/ 0.7; hospitalizations, 0.21/0.04, 0.24/0.04, and 0.40/0.09; oral steroid treatments; 1.3/0.5, 1.2/0.7, and 1.3/0.9; absenteeism from work/school, 9.6/5.2, 8.8/2.2, and 6.3/2.9. Between-group differences did not reach statistical significance (p > 0.05). Asthma knowledge increased in both educated groups compared with the control group (p < 0.001) as did short-term compliance with inhaled corticosteroids. These results confirm that treatment optimization coupled with sustained high quality care in motivated patients can lead to a significant decrease in asthma morbidity. In such clinical settings, structured asthma education significantly improved short-term compliance with treatment and knowledge about asthma, although it could not add extra benefit with regard to morbidity. Nevertheless, this study does not refute the potential benefit of educational interventions aimed at improving asthma-related morbidity over a longer time period or in patients with less optimal care or with high-risk factors.
