  • Management
  • Strategy
  1. Written action plan
    1. Based on symptoms or Peak Expiratory Flow
  2. Long term use of Inhaled Corticosteroids (persistent Asthma)
    1. Decrease airway inflammation
    2. Most effective medication for long-term control
  3. Add long acting Bronchodilator for moderate to Severe Asthma
  4. Intermittent and cautious use of Inhaled Beta Agonist
    1. Avoid more than 4 times per day
    2. Regular use beyond Exercise-related should prompt reevaluation to step-up therapy (see below)
  5. Consider Asthma-contributers (Mnemonic: Air-Smog)
    1. Allergans (pets, Dust mites, molds, pollens)
    2. Irritants and Infections
    3. Rhinitis (allergic) or Sinusitis (acute or chronic)
    4. Smoking, Sleep Apnea or Stress
    5. Medications (Beta Blockers, Aspirin, NSAIDS)
    6. Occupational
    7. Gastroesophageal Reflux Disease
  6. Prevent Exercise-induced and cold-induced Asthma
    1. See Exercise Induced Asthma
    2. Consider sodium Cromoglycate
  • Management
  • Approach to Uncontrolled Symptoms
  1. Indicators of uncontrolled Asthma
    1. Frequent use and early refills of rescue Inhaler
    2. Rescue Inhaler use more than twice weekly
    3. Awakening with nighttime symptoms more than twice monthly (over age 5)
    4. Within last 12 months, two or more courses of oral Corticosteroids, or Asthma hospital admission
  2. Assessment
    1. Consider Asthma control test (see resources below)
    2. Review Asthma medication use and Asthma Action Plan
    3. Confirm compliance
    4. Patient should demonstrate use of their rescue Inhaler (and with spacer)
    5. Obtain Spirometry at time of diagnosis and and consider repeating at times of worsening Asthma control
  3. Protocol
    1. Advance medications per stepped care and Asthma grouping (see below)
    2. For more significant symptoms start at a higher step (e.g. step 3 or 4)
    3. Re-evaluate every 2-4 weeks and step-up or step down management
    4. Advance stepped care for short-acting Bronchodilator more than twice weekly for acute symptom control

    2. Combination agent (long acting Bronchodilator and Corticosteroid) tapering (e.g. Advair)
      1. Start taper by decreasing Corticosteroid strength
      2. Next, change combination agent to Corticosteroid only (e.g. Flovent only)
      3. Next, decrease CorticosteroidInhaler strength by 25-50%
      4. Next, discontinue if no exacerbations
    3. Corticosteroid agent
      1. Start taper by decreasing Corticosteroid strength
      2. Next, decrease number of doses per day (e.g. from 2 puffs AM and 2 puffs PM, to 2 puffs AM and 1 puff PM)
      3. Next, discontinue if no exacerbations
  4. Back-up plan
