GINA Workshop Report Topics: Definition Burden of Asthma Risk Factors
Mechanisms Diagnosis and Classification Education and Delivery of Care Six Part Asthma Management Plan Research Recommendations

Definition of Asthma A chronic inflammatory disorder of the airways
Many cells and cellular elements play a role Chronic inflammation leads to an increase in airway hyperresponsiveness with recurrent episodes of wheezing, coughing, and shortness of breath Widespread, variable, and often reversible airflow limitation

Definition of Asthma Asthma is a chronic inflammatory disorder of the airways in which many cells and cellular elements play a role Chronic inflammation causes an associated increase in airway hyperresponsiveness that leads to recurrent episodes of wheezing, breathlessness, chest tightness, and coughing, particularly at night or in the early morning These episodes are usually associated with widespread but variable airflow obstruction that is often reversible either spontaneously or with treatment

Mechanisms Underlying the Definition of Asthma
Risk Factors (for development of asthma) INFLAMMATION Airway Hyperresponsiveness Airflow Obstruction Symptoms Risk Factors (for exacerbations)

Burden of Asthma Asthma is one of the most common chronic diseases worldwide Prevalence increasing in many countries, especially in children A major cause of school/work absence An overall increase in severity of asthma increases the pool of patients at risk for death

Burden of Asthma Health care expenditures very high
Developed economies might expect to spend 1-2 percent of total health care expenditures on asthma. Developing economies likely to face increased demand Poorly controlled asthma is expensive; investment in prevention medication likely to yield cost savings in emergency care

Risk Factors for Asthma
Host factors: predispose individuals to, or protect them from, developing asthma Environmental factors: influence susceptibility to development of asthma in predisposed individuals, precipitate asthma exacerbations, and/or cause symptoms to persist

Factors that Exacerbate Asthma
Allergens Air Pollutants Respiratory infections Exercise and hyperventilation Weather changes Sulfur dioxide Food, additives, drugs

Risk Factors that Lead to Asthma Development
Host Factors Genetic predisposition Atopy Airway hyperresponsiveness Gender Race/Ethnicity Environmental Factors Indoor allergens Outdoor allergens Occupational sensitizers Tobacco smoke Air Pollution Respiratory Infections Parasitic infections Socioeconomic factors Family size Diet and drugs Obesity

Is it Asthma? Recurrent episodes of wheezing
Troublesome cough at night Cough or wheeze after exercise Cough, wheeze or chest tightness after exposure to airborne allergens or pollutants Colds “go to the chest” or take more than 10 days to clear

Asthma Diagnosis History and patterns of symptoms Physical examination
Measurements of lung function Measurements of allergic status to identify risk factors

Clinical Features Before Treatment
Classification of Severity CLASSIFY SEVERITY Clinical Features Before Treatment Nocturnal Symptoms Symptoms FEV1 or PEF Continuous Limited physical activity STEP 4 Severe Persistent  60% predicted Variability > 30% Frequent % predicted Variability > 30% STEP 3 Moderate Persistent Daily Attacks affect activity > 1 time week STEP 2 Mild Persistent > 2 times a month  80% predicted Variability % > 1 time a week but < 1 time a day < 1 time a week Asymptomatic and normal PEF between attacks STEP 1 Intermittent  80% predicted Variability < 20%  2 times a month The presence of one feature of severity is sufficient to place patient in that category.

Six-Part Asthma Management Program
1. Educate Patients 2. Assess and Monitor Severity 3. Avoid Exposure to Risk Factors 4. Establish Medication Plans for Chronic Management: Adults and Children 5. Establish Plans for Managing Exacerbations 6. Provide Regular Follow-up Care

1. Educate patients to develop a partnership in asthma management 2. Assess and monitor asthma severity with symptom reports and measures of lung function as much as possible 3. Avoid exposure to risk factors 4. Establish medication plans for chronic management in children and adults 5. Establish individual plans for managing exacerbations 6. Provide regular follow-up care

Goals of Long-term Management
Six-part Asthma Management Program Goals of Long-term Management Achieve and maintain control of symptoms Prevent asthma episodes or attacks Maintain pulmonary function as close to normal levels as possible Maintain normal activity levels, including exercise Avoid adverse effects from asthma medications Prevent development of irreversible airflow limitation Prevent asthma mortality

Control of Asthma Minimal (ideally no) chronic symptoms
Six-part Asthma Management Program Control of Asthma Minimal (ideally no) chronic symptoms Minimal (infrequent) exacerbations No emergency visits Minimal (ideally no) need for “as needed” use of β2-agonist No limitations on activities, including exercise PEF circadian variation of less than 20 percent (Near) normal PEF Minimal (or no) adverse effects from medicine

. Six-Part Asthma Management Program
The most effective management is to prevent airway inflammation by eliminating the causal factors Asthma can be effectively controlled in most patients, although it can not be cured The major factors contributing to asthma morbidity and mortality are under- diagnosis and inappropriate treatment

Any asthma more severe than intermittent asthma is more effectively controlled by treatment to suppress and reverse airway inflammation than by treatment only of acute bronchoconstriction and symptoms

Six-part Asthma Management Program Part 1: Educate Patients to Develop a Partnership
Patient education involves a partnership between the patient and health care professional(s) with frequent revision and reinforcement Aim is guided self-management – giving patients the ability to control their asthma Interventions, including use of written action plans, have been shown to reduce morbidity in both children and adults

Six-part Asthma Management Program Part 1: Educate Patients to Develop a Partnership
Guidelines on asthma management should be available but adapted and adopted for local use by local asthma planning teams Clear communication between health care professionals and asthma patients is key to enhancing compliance

Provide information about asthma
Six-part Asthma Management Program Part 1: Educate Patients to Develop a Partnership Educate continually Include the family Provide information about asthma Provide training on self-management skills Emphasize a partnership among health care providers, the patient, and the patient’s family

Medication Usage Patient/Physician
Six-part Asthma Management Program Factors Associated with Non-Compliance in Asthma Care Medication Usage Difficulties associated with inhalers Complicated regimens Fears about, or actual side effects Cost Patient/Physician Misunderstanding/lack of information Underestimation of severity Attitudes toward ill health Cultural factors Poor communication

Six-part Asthma Management Program
Part 2: Assess and Monitor Asthma Severity with Symptom Reports and Measures of Lung Function Symptom reports Use of reliever medication Nighttime symptoms Activity limitations Spirometry for initial assessment. Peak Expiratory Flow for follow-up: Assess severity Assess response to therapy PEF monitoring at home Important for those with poor perception of symptoms Daily measurement recorded in a diary Assesses the severity and predicts worsening Guides the use of a zone system for asthma self-management Arterial blood gas for severe exacerbations

Six-part Asthma Management Program Part 3: Avoid Exposure to Risk Factors
Methods to prevent onset of asthma are not yet available but this remains an important goal Measures to reduce exposure to causes of asthma exacerbations (e.g. allergens, pollutants, foods and medications) should be implemented whenever possible

Six-part Asthma Management Program Part 4: Establish Medication Plans for Long-Term Asthma Management in Infants and Children At present, inhaled glucocorticosteroids are the most effective controller medications and are recommended for persistent asthma at any step of severity Long-term treatment with inhaled glucocorticosteroids markedly reduces the frequency and severity of exacerbations

Reduce exposure to indoor allergens Avoid tobacco smoke
Six-part Asthma Management Program Part 3: Avoid Exposure to Risk Factors Reduce exposure to indoor allergens Avoid tobacco smoke Avoid vehicle emission Identify irritants in the workplace Explore role of infections on asthma development, especially in children and young infants

Part 4: Establish Medication Plans for Long-Term Asthma Management
Six-part Asthma Management Program Part 4: Establish Medication Plans for Long-Term Asthma Management A stepwise approach to pharmacological therapy is recommended The aim is to accomplish the goals of therapy with the least possible medication Although in many countries traditional methods of healing are used, their efficacy has not yet been established and their use can therefore not be recommended

Stepwise Approach to Asthma Therapy
Part 4: Long-term Asthma Management Stepwise Approach to Asthma Therapy The choice of treatment should be guided by: Severity of the patient’s asthma Patient’s current treatment Pharmacological properties and availability of the various forms of asthma treatment Economic considerations Cultural preferences and differing health care systems need to be considered.

Allergen-specific Immunotherapy
Part 4: Long-term Asthma Management Allergen-specific Immunotherapy Greatest benefit of specific immunotherapy using allergen extracts has been obtained in the treatment of allergic rhinitis A number of questions must be addressed regarding the role of specific immunotherapy in asthma therapy Specific immunotherapy should be considered only after strict environmental avoidance and pharmacologic intervention, including inhaled glucocorticosteroids, have failed to control asthma Perform only by trained physician

Six-part Asthma Management Program Part 4: Establish Medication Plans for Long-Term Asthma Management in Infants and Children Childhood and adult asthma share the same underlying mechanisms. However, because of processes of growth and development, effects of asthma treatments in children differ from those in adults.

Six-part Asthma Management Program Part 4: Establish Medication Plans for Long-Term Asthma Management in Infants and Children Many asthma medications (e.g. glucocorticosteroids, β2- agonists, theophylline) are metabolized faster in children than in adults, and younger children tend to metabolize medications faster than older children

Six-part Asthma Management Program Part 4: Establish Medication Plans for Long-Term Asthma Management in Infants and Children Long-term treatment with inhaled glucocorticosteroids has not been shown to be associated with any increase in osteoporosis or bone fracture Studies including a total of over 3,500 children treated for periods of 1 – 13 years have found no sustained adverse effect of inhaled glucocorticosteroids on growth

Six-part Asthma Management Program Part 4: Establish Medication Plans for Long-Term Asthma Management in Infants and Children Rapid-acting inhaled β2- agonists are the most effective reliever therapy for children These medications are the most effective bronchodilators available and are the treatment of choice for acute asthma symptoms

Recommended Asthma Medications Step 1: Children

Treatment of exacerbations depends on: The patient
Six-part Asthma Management Program Part 5: Establish Plans for Managing Exacerbations Treatment of exacerbations depends on: The patient Experience of the health care professional Therapies that are the most effective for the particular patient Availability of medications Emergency facilities

Primary therapies for exacerbations:
Six-part Asthma Management Program Part 5: Establish Plans for Managing Exacerbations Primary therapies for exacerbations: Repetitive administration of rapid-acting inhaled β2-agonist Early introduction of systemic glucocorticosteroids Oxygen supplementation Closely monitor response to treatment with serial measures of lung function

Severe exacerbations are life-threatening medical emergencies
Six-part Asthma Management Program Part 5: Managing Severe Asthma Exacerbations Severe exacerbations are life-threatening medical emergencies Care must be expeditious and treatment is often most safely undertaken in a hospital or hospital-based emergency department

Emergency Department Management Acute Asthma
Initial Assessment History, Physical Examination, PEF or FEV1 Initial Therapy Bronchodilators; O2 if needed Incomplete/Poor Response Add Systemic Glucocorticosteroids Good Response Discharge Poor Response Admit to Hospital Good Response Observe for at least 1 hour If Stable, Discharge to Home Respiratory Failure Admit to ICU

Continual monitoring is essential to assure that
Six-part Asthma Management Program Part 6: Provide Regular Follow-up Care Continual monitoring is essential to assure that therapeutic goals are met. Frequent follow-up visits are necessary to review: Home PEF and symptom records Techniques in use of medications Risk factors and their control Once asthma control is established, follow-up visits should be scheduled (at 1 to 6 month intervals as appropriate)

Six-part Asthma Management Program Special Considerations
Special considerations are required to manage asthma in relation to: Pregnancy Surgery Physical activity Rhinitis, sinusitis, and nasal polyps Occupational asthma Respiratory infections Gastroesophageal reflux Aspirin-induced asthma

Six-part Asthma Management Program: Summary
Asthma can be effectively controlled, although it cannot be cured Effective asthma management programs include education, objective measures of lung function, environmental control, and pharmacologic therapy A stepwise approach to pharmacologic therapy is recommended. The aim is to accomplish the goals of therapy with the least possible medication

Six-part Asthma Management Program: Summary (continued)
Anything more than mild, occasional asthma is more effectively controlled by suppressing inflammation than by only treating acute bronchospasm The availability of varying forms of treatment, cultural preferences, and differing health care systems need to be considered
