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

Page 7: Update GINA 2006

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

Page 8: Update GINA 2006

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

5. Establish Plans for Managing

Exacerbations

6. Provide Regular Follow-up Care

The recommendations for asthma management are laid out in five interrelated components of therapy:

1. Develop Patient/Doctor Partnership

2. Identify and Reduce Exposure to Risk Factors

3. Assess, Treat, and Monitor Asthma

4. Manage Asthma Exacerbations

5. Special Considerations

Page 23: Update GINA 2006

Levels of Asthma ControlCharacteristic Controlled

(All of the following)

Partly Controlled

(Any measure present in any week)

Uncontrolled

Daytime symptoms None (twice or less/week)

More than twice/week Three or more features

of partly controlled

asthma present

Limitations of activities None Any

Nocturnal symptoms/awakening

None Any

Need for reliever/

rescue treatment

None (twice or less/week)

More than twice/week

Lung function (PEF or FEV1)‡

Normal < 80% predicted or personal best (if known)

Exacerbations None One or more/year* One in any week†

* Any exacerbation should prompt review of maintenance treatment to ensure that it is adequate.† By definition, an exacerbation in any week makes that an uncontrolled asthma week.‡ Lung function is not a reliable test for children 5 years and younger.
